The display area A10 is a place where the organic light emitting diode display panel 100 generates an image, but the image is not generated in the first non-display area N11.

在圖1B所示的實施例中，控制基板110包括元件陣列基板111與絕緣層112，其中絕緣層112形成在元件陣列基板111上，並覆蓋元件陣列基板111的上表面。元件陣列基板111可以具有多個開關元件（未繪示）以及多個導電層（未繪示），其中導電層位於元件陣列基板111的上表面，並且被絕緣層112覆蓋，而這些開關元件電性連接這些導電層。In the embodiment shown in FIG. 1B, the control substrate 110 includes an element array substrate 111 and an insulating layer 112, wherein the insulating layer 112 is formed on the element array substrate 111 and covers the upper surface of the element array substrate 111. The element array substrate 111 may have a plurality of switching elements (not shown) and a plurality of conductive layers (not shown). The conductive layer is located on the upper surface of the element array substrate 111 and is covered by the insulating layer 112, and these switching elements are electrically conductive.

Silicon or silicon oxide, and the insulating layer 112 can be formed by chemical vapor deposition (CVD).

有機發光二極體顯示面板100還包括平坦層120b以及畫素定義層130。平坦層120b設置於控制基板110上，並分布於顯示區A10與第一非顯示區N11。以圖1B為例，平坦層120b可以從顯示區A10沿著控制基板110的上表面110u而延伸至第一非顯示區N11。畫素定義層130設置於平坦層120b上，並且分布於顯示區A10。另外，控制基板110的絕緣層112可以設置在元件陣列基板111以及平坦層120b之間。The organic light emitting diode display panel 100 further includes a flat layer 120 b and a pixel definition layer 130. The flat layer 120b is disposed on the control substrate 110 and distributed in the display area A10 and the first non-display area N11. Taking FIG. 1B as an example, the flat layer 120b may extend from the display area A10 along the upper surface 110u of the control substrate 110 to the first non-display area N11. The pixel definition layer 130 is disposed on the flat layer 120b and distributed in the display area A10. In addition, the insulating layer 112 of the control substrate 110 may be disposed between the element array substrate 111 and the flat layer 120b.

在圖1B所示的實施例中，畫素定義層130主要分布於顯示區A10，其中畫素定義層130的一部分可以分布於第一非顯示區N11內，但畫素定義層130沒有分布於整個第一非顯示區N11。另外，在其他實施例中，畫素定義層130也可以僅分布於顯示區A10，不分布於第一非顯示區N11。所以，圖1B僅供舉例說明，並不限制畫素定義層130的分布區域。In the embodiment shown in FIG. 1B, the pixel definition layer 130 is mainly distributed in the display area A10. A part of the pixel definition layer 130 may be distributed in the first non-display area N11, but the pixel definition layer 130 is not distributed in the first non-display area N11. The entire first non-display area N11. In addition, in other embodiments, the pixel definition layer 130 may also be distributed only in the display area A10 and not in the first non-display area N11. Therefore, FIG. 1B is for illustration only, and does not limit the distribution area of the pixel definition layer 130.

畫素定義層130具有多個畫素開口130h，而有機發光二極體顯示面板100還包括多個有機發光二極體160。這些畫素開口130h皆位於顯示區A10內，而這些有機發光二極體160分別設置於這些畫素開口130h內。以圖1B為例，這些有機發光二極體160可以一對一地設置於這些畫素開口130h內。The pixel definition layer 130 has a plurality of pixel openings 130 h, and the organic light emitting diode display panel 100 further includes a plurality of organic light emitting diodes 160. The pixel openings 130h are all located in the display area A10, and the organic light emitting diodes 160 are respectively disposed in the pixel openings 130h.

絕緣層112與平坦層120b內可以存有多個接觸窗（未繪示），其為貫孔（through hole），而各個接觸窗的側壁可被金屬層覆蓋，以形成內連線結構（intersection structure）。內連線結構連接有機發光二極體160的電極（例如陽極）與元件陣列基板111的導電層。因此，元件陣列基板111的開關元件能經由導電層與內連線結構而電性連接有機發光二極體160，以控制有機發光二極體160發光。當開關元件為薄膜電晶體時，開關元件具有閘極、汲極與源極，而開關元件的汲極經由導電層與內連線結構而電性連接有機發光二極體160，以使開關元件能控制有機發光二極體160發光。A plurality of contact windows (not shown) may be stored in the insulating layer 112 and the flat layer 120b, which are through holes, and the sidewalls of each contact window may be covered by a metal layer to form an interconnect structure (intersection structure). The interconnect structure connects the electrode (for example, the anode) of the organic light emitting diode 160 and the conductive layer of the element array substrate 111. Therefore, the switching elements of the element array substrate 111 can be electrically connected to the organic light-emitting diode 160 through the conductive layer and the interconnection structure to control the organic light-emitting diode 160 to emit light. When the switching element is a thin film transistor, the switching element has a gate, a drain, and a source, and the drain of the switching element is electrically connected to the organic light emitting diode 160 through the conductive layer and the interconnection structure, so that the switching element The organic light emitting diode 160 can be controlled to emit light.

在本實施例中，這些有機發光二極體160可發出不同顏色的光。例如，這些有機發光二極體160可以是多個紅光發光二極體、多個綠光發光二極體以及多個藍光發光二極體，並能發出紅光、綠光與藍光。如此，這些位於畫素開口130h內的有機發光二極體160每一者可視為有機發光二極體顯示面板100的子畫素（sub-pixel），而這些有機發光二極體160所發出的紅光、藍光與綠光能形成影像，讓有機發光二極體顯示面板100能顯示影像。In this embodiment, these organic light emitting diodes 160 can emit light of different colors. For example, the organic light-emitting diodes 160 may be multiple red light-emitting diodes, multiple green light-emitting diodes, and multiple blue light-emitting diodes, and can emit red light, green light, and blue light. In this way, each of the organic light-emitting diodes 160 located in the pixel opening 130h can be regarded as a sub-pixel of the organic light-emitting diode display panel 100, and the organic light-emitting diodes 160 emit Red light, blue light and green light can form images, so that the organic light emitting diode display panel 100 can display images.

須說明的是，在其他未繪示的實施例中，這些有機發光二極體160可發出實質上相同顏色的光線。例如，這些有機發光二極體160皆可發出白光，而有機發光二極體顯示面板100可以還包括彩色濾光基板（未繪示），其中彩色濾光基板設置於控制基板110的對面，並能過濾從有機發光二極體160而來的白光，以產生紅光、綠光與藍光。如此，利用彩色濾光基板，這些發出白光的有機發光二極體160也能讓有機發光二極體顯示面板100顯示影像。It should be noted that in other embodiments not shown, the organic light emitting diodes 160 can emit light of substantially the same color. For example, these organic light-emitting diodes 160 can emit white light, and the organic light-emitting diode display panel 100 may further include a color filter substrate (not shown), wherein the color filter substrate is disposed on the opposite side of the control substrate 110, and The white light from the organic light emitting diode 160 can be filtered to generate red light, green light and blue light. In this way, by using the color filter substrate, these organic light emitting diodes 160 that emit white light can also enable the organic light emitting diode display panel 100 to display images.

有機發光二極體顯示面板100還包括多道圍牆，其中這些圍牆圍繞顯示區A10。以圖1A與圖1B為例，有機發光二極體顯示面板100可以包括兩道圍牆：第一圍牆140a與第二圍牆140b，其中第一圍牆140a與第二圍牆140b皆設置於第一非顯示區N11內的平坦層120b上，並且圍繞顯示區A10。第二圍牆140b圍繞第一圍牆140a，所以第一圍牆140a會較靠近畫素定義層130，而第二圍牆140b會較遠離畫素定義層130。The organic light emitting diode display panel 100 further includes a plurality of walls, wherein the walls surround the display area A10. Taking FIGS. 1A and 1B as an example, the organic light emitting diode display panel 100 may include two enclosure walls: a first enclosure wall 140a and a second enclosure wall 140b, wherein the first enclosure wall 140a and the second enclosure wall 140b are both set in the first non-display The area N11 is on the flat layer 120b and surrounds the display area A10. The second wall 140b surrounds the first wall 140a, so the first wall 140a is closer to the pixel definition layer 130, and the second wall 140b is farther away from the pixel definition layer 130.

由於第一圍牆140a與第二圍牆140b兩者皆設置於平坦層120b上，因此第一圍牆140a與第二圍牆140b兩者相對於平坦層120b的高度H14皆高於顯示區A10內的畫素定義層130相對於平坦層120b的高度H13，以使第一圍牆140a與第二圍牆140b具有較高的高度H14，其可以介於0.1微米至100微米之間。Since both the first fence 140a and the second fence 140b are disposed on the flat layer 120b, the height H14 of the first fence 140a and the second fence 140b relative to the flat layer 120b are both higher than the pixels in the display area A10 The height H13 of the layer 130 relative to the flat layer 120b is defined so that the first fence 140a and the second fence 140b have a higher height H14, which may be between 0.1 micrometers and 100 micrometers.

在圖1B所示的實施例中，第一圍牆140a與第二圍牆140b兩者相對於平坦層120b的高度H14實質上相等，但在其他實施例中，第一圍牆140a與第二圍牆140b兩者的高度H14可以不相等。不過，即使第一圍牆140a與第二圍牆140b兩者的高度H14不同，第一圍牆140a與第二圍牆140b任一者的高度H14會大於畫素定義層130的高度H13。In the embodiment shown in FIG. 1B, the height H14 of the first fence 140a and the second fence 140b relative to the flat layer 120b is substantially equal, but in other embodiments, the first fence 140a and the second fence 140b are two The height H14 of the persons may not be equal. However, even if the height H14 of the first fence 140a and the second fence 140b are different, the height H14 of any one of the first fence 140a and the second fence 140b will be greater than the height H13 of the pixel definition layer 130.

在本實施例中，第一圍牆140a可包括第一壁體141a與第一頂部142a，其中第一壁體141a設置於平坦層120b上，而第一頂部142a設置於第一壁體141a上方，並沿第一壁體141a延伸。所以，第一壁體141a會位在第一頂部142a與平坦層120b之間。與第一圍牆140a相同，第二圍牆140b可包括第二壁體141b與第二頂部142b，其中第二壁體141b設置於平坦層120b上，而第二頂部142b設置於第二壁體141b上方，並沿著第二壁體141b延伸。因此，第二壁體141b也位在第二頂部142b與平坦層120b之間。In this embodiment, the first wall 140a may include a first wall 141a and a first top 142a, wherein the first wall 141a is disposed on the flat layer 120b, and the first top 142a is disposed above the first wall 141a, And extend along the first wall 141a. Therefore, the first wall 141a is located between the first top 142a and the flat layer 120b. Same as the first wall 140a, the second wall 140b may include a second wall 141b and a second top 142b, wherein the second wall 141b is disposed on the flat layer 120b, and the second top 142b is disposed above the second wall 141b , And extend along the second wall 141b. Therefore, the second wall 141b is also located between the second top portion 142b and the flat layer 120b.

第一圍牆140a與第二圍牆140b之間會形成第一溝槽T11。由於第一圍牆140a與第二圍牆140b皆設置在平坦層120b上，所以第一溝槽T11會形成於平坦層120b的上方，並圍繞顯示區A10與第一圍牆140a。此外，第一溝槽T11的寬度W11可以介於3微米至100微米之間，但此寬度W11的範圍不用於限制本發明。A first trench T11 is formed between the first fence 140a and the second fence 140b. Since the first fence 140a and the second fence 140b are both disposed on the flat layer 120b, the first trench T11 is formed above the flat layer 120b and surrounds the display area A10 and the first fence 140a. In addition, the width W11 of the first trench T11 may be between 3 μm and 100 μm, but the range of the width W11 is not used to limit the present invention.

第一圍牆140a與第二圍牆140b可以採用高分子材料製成。例如，第一壁體141a、第二壁體141b、第一頂部142a以及第二頂部142b皆可採用光阻來製成，其中第一壁體141a與第二壁體141b兩者可採用一層光阻來製成，而第一頂部142a與第二頂部142b兩者可採用另一層光阻來製成。The first enclosure wall 140a and the second enclosure wall 140b may be made of polymer materials. For example, the first wall 141a, the second wall 141b, the first top 142a, and the second top 142b can all be made of photoresist, and the first wall 141a and the second wall 141b can both use a layer of light. The first top portion 142a and the second top portion 142b can be made by using another layer of photoresist.

形成第一壁體141a、第二壁體141b、第一頂部142a與第二頂部142b的方法可以包括曝光與顯影，其中第一壁體141a、第二壁體141b以及畫素定義層130可以由同一層光阻經曝光與顯影之後而形成。因此，第一壁體141a與第二壁體141b兩者厚度實質上彼此相同，並且可以實質上相同於高度H13。The method of forming the first wall 141a, the second wall 141b, the first top 142a and the second top 142b may include exposure and development. The first wall 141a, the second wall 141b and the pixel definition layer 130 may be formed by The same layer of photoresist is formed after exposure and development. Therefore, the thicknesses of the first wall body 141a and the second wall body 141b are substantially the same as each other, and may be substantially the same as the height H13.

有機發光二極體顯示面板100還包括模封層150，而模封層150設置於控制基板110上，並且全面性地覆蓋平坦層120b、畫素定義層130、第一圍牆140a以及第二圍牆140b，其中模封層150能阻擋外界氧氣與水氣滲入，而第一圍牆140a與第二圍牆140b能阻礙氧氣與水氣的滲入。因此，第一圍牆140a、第二圍牆140b與模封層150能保護顯示區A10內的有機發光二極體160，防止有機發光二極體160遭受氧氣及/或水氣破壞。The organic light emitting diode display panel 100 further includes a mold sealing layer 150, and the mold sealing layer 150 is disposed on the control substrate 110, and comprehensively covers the flat layer 120b, the pixel definition layer 130, the first fence 140a, and the second fence 140b, wherein the mold sealing layer 150 can block the penetration of external oxygen and moisture, and the first enclosure wall 140a and the second enclosure 140b can block the penetration of oxygen and moisture. Therefore, the first enclosure wall 140a, the second enclosure wall 140b and the molding layer 150 can protect the organic light emitting diode 160 in the display area A10, and prevent the organic light emitting diode 160 from being damaged by oxygen and/or moisture.

模封層150可包括有機密封層151，而有機密封層151設置於平坦層120b上，並分布於顯示區A10。在圖1B所示的實施例中，有機密封層151分布於顯示區A10，而且一部分有機密封層151可分布於部分第一非顯示區N11，但有機密封層151沒有分布於整個第一非顯示區N11。The molding layer 150 may include an organic sealing layer 151, and the organic sealing layer 151 is disposed on the flat layer 120b and distributed in the display area A10. In the embodiment shown in FIG. 1B, the organic sealing layer 151 is distributed in the display area A10, and a part of the organic sealing layer 151 may be distributed in a part of the first non-display area N11, but the organic sealing layer 151 is not distributed in the entire first non-display area. District N11.

第一圍牆140a圍繞有機密封層151。具體而言，有機密封層151可利用印刷或噴塗的方式形成，而有機密封層151可由有機的液態材料經固化或乾燥之後而形成。第一圍牆140a會早於有機密封層151形成。在第一圍牆140a形成之後，第一圍牆140a會圍繞出一個容置空間（未標示），而顯示區A10位於此容置空間內（如圖1A所示）。接著，將用於形成有機密封層151的液態材料填入於容置空間中。之後，固化或乾燥此液態材料，形成被第一圍牆140a圍繞的有機密封層151。The first wall 140 a surrounds the organic sealing layer 151. Specifically, the organic sealing layer 151 can be formed by printing or spraying, and the organic sealing layer 151 can be formed by curing or drying an organic liquid material. The first enclosure wall 140a may be formed earlier than the organic sealing layer 151. After the first enclosure wall 140a is formed, the first enclosure wall 140a surrounds an accommodating space (not labeled), and the display area A10 is located in the accommodating space (as shown in FIG. 1A). Next, the liquid material used to form the organic sealing layer 151 is filled in the accommodating space. Afterwards, the liquid material is cured or dried to form the organic sealing layer 151 surrounded by the first wall 140a.

在本實施例中，用於形成有機密封層151的液態材料會被完全侷限在第一圍牆140a所圍繞的容置空間內。然而，在其他實施例中，當填入上述液態材料於容置空間時，一些液態材料可能會進入第一溝槽T11內。例如，容置空間內的液態材料太多，以至於一部分液態材料從第一圍牆140a溢流到第一溝槽T11。或者，當利用噴嘴將液態材料填入於容置空間時，噴嘴不慎將少部分液態材料滴入或噴入至第一溝槽T11內，因此用於形成有機密封層151的液態材料也可以部分分布在第一溝槽T11內。In this embodiment, the liquid material used to form the organic sealing layer 151 is completely confined in the accommodating space surrounded by the first wall 140a. However, in other embodiments, when the above-mentioned liquid material is filled in the accommodating space, some liquid material may enter the first trench T11. For example, there is too much liquid material in the accommodating space, so that part of the liquid material overflows from the first wall 140a to the first trench T11. Or, when a nozzle is used to fill the accommodating space with a liquid material, the nozzle accidentally drops or sprays a small part of the liquid material into the first groove T11, so the liquid material used to form the organic sealing layer 151 can also be used. Partly distributed in the first trench T11.

模封層150還可包括無機密封層152。無機密封層152設置於控制基板110上，並且覆蓋有機密封層151、第一圍牆140a以及第二圍牆140b，其中無機密封層152更可以填滿第一溝槽T11，如圖1B所示。此外，無機密封層152可以採用化學氣相沉積（CVD）來形成。The molding layer 150 may further include an inorganic sealing layer 152. The inorganic sealing layer 152 is disposed on the control substrate 110 and covers the organic sealing layer 151, the first enclosure wall 140a, and the second enclosure wall 140b. The inorganic sealing layer 152 can further fill the first trench T11, as shown in FIG. 1B. In addition, the inorganic sealing layer 152 may be formed using chemical vapor deposition (CVD).

在本實施例中，第一圍牆140a具有鄰近顯示區A10的第一壁面S11b，而第二圍牆140b具有遠離顯示區A10的第二壁面S12b，其中第一壁面S11b與第二壁面S12b皆位在第一溝槽T11外。換句話說，第一壁面S11b與第二壁面S12b都不是第一溝槽T11的側壁。此外，第一溝槽T11圍繞第一壁面S11b，而第二壁面S12b圍繞第一溝槽T11與第一壁面S11b。In this embodiment, the first wall 140a has a first wall surface S11b adjacent to the display area A10, and the second wall 140b has a second wall surface S12b away from the display area A10, wherein the first wall surface S11b and the second wall surface S12b are both located Outside the first trench T11. In other words, neither the first wall surface S11b nor the second wall surface S12b is a side wall of the first trench T11. In addition, the first groove T11 surrounds the first wall surface S11b, and the second wall surface S12b surrounds the first groove T11 and the first wall surface S11b.

由於第一圍牆140a與第二圍牆140b具有較高的高度H14，因此由第一圍牆140a圍繞而成的容置空間能容納較多用於形成有機密封層151的液態材料，以增加有機密封層151的體積。即使縮小第一壁面S11b與第二壁面S12b之間的距離140w，例如讓距離140w介於3微米至1000微米之間，有機密封層151的體積依然可以增加。Since the first wall 140a and the second wall 140b have a relatively high height H14, the accommodating space surrounded by the first wall 140a can accommodate more liquid materials for forming the organic sealing layer 151 to increase the organic sealing layer 151 volume of. Even if the distance 140w between the first wall surface S11b and the second wall surface S12b is reduced, for example, the distance 140w is between 3 μm and 1000 μm, the volume of the organic sealing layer 151 can still be increased.

另外，第一圍牆140a、第一溝槽T11以及第二圍牆140b三者會在第一非顯示區N11內佔據一塊環形區域，而距離140w代表此環形區域的粗細。由於距離140w可介於3至1000微米之間，因此上述環形區域可以具有較細的寬度。換句話說，第一圍牆140a、第一溝槽T11與第二圍牆140b三者在第一非顯示區N11內會佔據較小的面積，以使有機發光二極體顯示面板100有利於製作成窄邊框型顯示器，滿足現今窄邊框化的發展趨勢。In addition, the first fence 140a, the first trench T11, and the second fence 140b occupy an annular area in the first non-display area N11, and the distance 140w represents the thickness of the annular area. Since the distance 140w can be between 3 and 1000 microns, the above-mentioned annular region can have a narrower width. In other words, the first enclosure wall 140a, the first trench T11, and the second enclosure wall 140b occupy a relatively small area in the first non-display area N11, so that the organic light emitting diode display panel 100 can be easily manufactured. Narrow bezel displays meet the current development trend of narrow bezels.

圖1C是本發明至少一實施例的有機發光二極體顯示面板的剖面示意圖。請參閱圖1C，有機發光二極體顯示面板100C與前述有機發光二極體顯示面板100相似，而有機發光二極體顯示面板100C唯一不同於有機發光二極體顯示面板100的特徵在於：有機發光二極體顯示面板100C的平坦層120c具有外圍凹槽121c。FIG. 1C is a schematic cross-sectional view of an organic light emitting diode display panel according to at least one embodiment of the invention. 1C, the organic light emitting diode display panel 100C is similar to the aforementioned organic light emitting diode display panel 100, and the organic light emitting diode display panel 100C is only different from the organic light emitting diode display panel 100 in that it is organic The flat layer 120c of the light emitting diode display panel 100C has a peripheral groove 121c.

外圍凹槽121c位於第一非顯示區N11內，並且圍繞顯示區A10，而第一圍牆140a圍繞外圍凹槽121c。在本實施例中，外圍凹槽121c的深度等於平坦層120c的厚度，所以外圍凹槽121c延伸至平坦層120c的相對兩表面。例如，在圖1C中，外圍凹槽121c是從平坦層120c的上表面延伸至平坦層120c的下表面。換句話說，外圍凹槽121c是貫穿平坦層120c而形成。The peripheral groove 121c is located in the first non-display area N11 and surrounds the display area A10, and the first wall 140a surrounds the peripheral groove 121c. In this embodiment, the depth of the peripheral groove 121c is equal to the thickness of the flat layer 120c, so the peripheral groove 121c extends to two opposite surfaces of the flat layer 120c. For example, in FIG. 1C, the peripheral groove 121c extends from the upper surface of the flat layer 120c to the lower surface of the flat layer 120c. In other words, the peripheral groove 121c is formed through the flat layer 120c.

由於第一圍牆140a圍繞外圍凹槽121c，因此有機密封層151能填滿外圍凹槽121c，以使有機發光二極體顯示面板100C能透過外圍凹槽121c而容納較多的有機密封層151，以提升模封層150阻擋外界氧氣與水氣滲入的能力，保護有機發光二極體160免於遭受氧氣及/或水氣破壞。Since the first wall 140a surrounds the peripheral groove 121c, the organic sealing layer 151 can fill the peripheral groove 121c, so that the organic light emitting diode display panel 100C can pass through the peripheral groove 121c to accommodate more organic sealing layer 151. In order to improve the ability of the mold sealing layer 150 to block the penetration of external oxygen and moisture, the organic light emitting diode 160 is protected from oxygen and/or moisture damage.

圖1D是本發明至少一實施例的有機發光二極體顯示面板的剖面示意圖。請參閱圖1D，圖1D所示的有機發光二極體顯示面板100D與圖1B所示的有機發光二極體顯示面板100相似，其中有機發光二極體顯示面板100D的俯視外觀實質上相同於有機發光二極體顯示面板100，如圖1A所示。因此，這裡省略繪製有機發光二極體顯示面板100D的俯視示意圖。FIG. 1D is a schematic cross-sectional view of an organic light emitting diode display panel according to at least one embodiment of the invention. Please refer to FIG. 1D. The organic light emitting diode display panel 100D shown in FIG. 1D is similar to the organic light emitting diode display panel 100 shown in FIG. The organic light emitting diode display panel 100 is shown in FIG. 1A. Therefore, drawing the schematic top view of the organic light emitting diode display panel 100D is omitted here.

而有機發光二極體顯示面板100D唯一不同於有機發光二極體顯示面板100的特徵在於：有機發光二極體顯示面板100D所包括的第一圍牆149a與第二圍牆149b在結構上不同於前述實施例中的第一圍牆140a與第二圍牆140b，而且有機發光二極體顯示面板100D還包括前述實施例所沒有的墊層170。The only feature of the organic light emitting diode display panel 100D that is different from the organic light emitting diode display panel 100 is that the first wall 149a and the second wall 149b included in the organic light emitting diode display panel 100D are different in structure from the foregoing The first enclosure wall 140a and the second enclosure wall 140b in the embodiment, and the organic light emitting diode display panel 100D further includes a cushion layer 170 that is not included in the foregoing embodiment.

墊層170設置於第一非顯示區N11內，並且位於平坦層120b上，而第一圍牆149a與第二圍牆149b設置於墊層170上，以使位於第一圍牆149a與第二圍牆149b之間的第一溝槽T12形成於墊層170的上方。第一溝槽T12的寬度W12可以介於3微米至100微米之間，所以第一溝槽T12的寬度W12可以等於圖1B中的寬度W11。不過，寬度W12並不限制在3微米至100微米之間，即寬度W12的數值可以落在上述範圍以外。The cushion layer 170 is arranged in the first non-display area N11 and on the flat layer 120b, and the first fence 149a and the second fence 149b are arranged on the cushion layer 170 so as to be located between the first fence 149a and the second fence 149b. The first trench T12 is formed above the cushion layer 170. The width W12 of the first trench T12 may be between 3 μm and 100 μm, so the width W12 of the first trench T12 may be equal to the width W11 in FIG. 1B. However, the width W12 is not limited to between 3 microns and 100 microns, that is, the value of the width W12 may fall outside the above range.

墊層170可以採用高分子材料製成，例如光阻。墊層170與畫素定義層130可以由同一層光阻經曝光與顯影之後而形成，所以墊層170與畫素定義層130兩者厚度可以實質上彼此相同，並可實質上相同於高度H13。第一圍牆149a與第二圍牆149b兩者的構成材料與形成方法皆可相同於圖1B中的第一頂部142a與第二頂部142b兩者的構成材料與形成方法，而第一圍牆149a與第二圍牆149b兩者可由同一層光阻經曝光與顯影之後而形成。The cushion layer 170 may be made of a polymer material, such as photoresist. The cushion layer 170 and the pixel definition layer 130 can be formed by the same layer of photoresist after exposure and development, so the thickness of the cushion layer 170 and the pixel definition layer 130 can be substantially the same as each other, and can be substantially the same as the height H13 . The constituent materials and forming methods of both the first wall 149a and the second wall 149b can be the same as those of the first top 142a and the second top 142b in FIG. 1B, and the first wall 149a and the second wall 149a Both walls 149b can be formed by the same layer of photoresist after exposure and development.

第一圍牆149a具有鄰近顯示區A10的第一壁面S11d，而第二圍牆149b具有遠離顯示區A10的第二壁面S12d，其中第一壁面S11d與第二壁面S12d皆位在第一溝槽T12外。與前述實施例相似，第一溝槽T12圍繞第一壁面S11d，而第二壁面S12d圍繞第一溝槽T12與第一壁面S11d。The first wall 149a has a first wall surface S11d adjacent to the display area A10, and the second wall 149b has a second wall surface S12d away from the display area A10, wherein the first wall surface S11d and the second wall surface S12d are both located outside the first groove T12 . Similar to the previous embodiment, the first groove T12 surrounds the first wall surface S11d, and the second wall surface S12d surrounds the first groove T12 and the first wall surface S11d.

第一壁面S11d與第二壁面S12d之間的距離149w可以介於3微米至1000微米之間，所以距離149w可以實質上等於圖1B中的距離140w。此外，在圖1D所示的實施例中，距離149w可以實質上等於墊層170的寬度，而且第一圍牆149a、第一溝槽T12與第二圍牆149b三者在第一非顯示區N11內所佔據的區域可以相同於墊層170在第一非顯示區N11內所佔據的區域。The distance 149w between the first wall surface S11d and the second wall surface S12d may be between 3 μm and 1000 μm, so the distance 149w may be substantially equal to the distance 140w in FIG. 1B. In addition, in the embodiment shown in FIG. 1D, the distance 149w may be substantially equal to the width of the cushion layer 170, and the first fence 149a, the first trench T12, and the second fence 149b are in the first non-display area N11 The occupied area may be the same as the area occupied by the cushion layer 170 in the first non-display area N11.

由於第一壁面S11d與第二壁面S12d之間的距離149w可介於3微米至1000微米之間，因此第一圍牆149a、第一溝槽T12與第二圍牆149b三者在第一非顯示區N11內佔據較小的面積，以使有機發光二極體顯示面板100D有利於製作成窄邊框型顯示器，滿足現今窄邊框化的發展趨勢。此外，在圖1D所示的實施例中，有機發光二極體顯示面板100D的平坦層120b可替換成圖1C中的平坦層120c，即圖1D中的平坦層120b可具有外圍凹槽121c。Since the distance 149w between the first wall surface S11d and the second wall surface S12d may be between 3 μm and 1000 μm, the first wall 149a, the first trench T12, and the second wall 149b are in the first non-display area N11 occupies a relatively small area, so that the organic light-emitting diode display panel 100D can be made into a narrow bezel display, which meets the current development trend of narrow bezels. In addition, in the embodiment shown in FIG. 1D, the flat layer 120b of the organic light emitting diode display panel 100D may be replaced with the flat layer 120c in FIG. 1C, that is, the flat layer 120b in FIG. 1D may have a peripheral groove 121c.

圖2是本發明另一實施例的有機發光二極體顯示面板的俯視示意圖。請參閱圖2，有別於前述實施例，圖2中的有機發光二極體顯示面板200的形狀實質上可以是三角形。具體而言，有機發光二極體顯示面板200包括控制基板210，其邊緣210e圍繞成三角形，其中控制基板210的顯示區A20的形狀實質上也是三角形，如圖2所示。2 is a schematic top view of an organic light emitting diode display panel according to another embodiment of the invention. Please refer to FIG. 2. Different from the foregoing embodiments, the shape of the organic light emitting diode display panel 200 in FIG. 2 can be substantially triangular. Specifically, the organic light emitting diode display panel 200 includes a control substrate 210, the edge 210e of which is surrounded to form a triangle, wherein the shape of the display area A20 of the control substrate 210 is also substantially a triangle, as shown in FIG. 2.

由於有機發光二極體顯示面板200的形狀實質上為三角形，因此有機發光二極體顯示面板200所包括的第一圍牆240a與第二圍牆240b也沿著邊緣210e而圍繞成三角形。此外，覆蓋第一圍牆240a、第二圍牆240b與控制基板210的模封層250，其外邊緣250e也是沿著邊緣210e而圍繞成三角形，如圖2所示。Since the shape of the organic light emitting diode display panel 200 is substantially a triangle, the first wall 240a and the second wall 240b included in the organic light emitting diode display panel 200 also surround the edge 210e to form a triangle. In addition, the outer edge 250e of the mold sealing layer 250 covering the first fence 240a, the second fence 240b and the control substrate 210 is also surrounded into a triangle along the edge 210e, as shown in FIG. 2.

須說明的是，雖然圖2中的有機發光二極體顯示面板200的形狀明顯不同於前述實施例中的有機發光二極體顯示面板100、100C與100D的形狀，但有機發光二極體顯示面板200的剖面結構卻實質上相同於有機發光二極體顯示面板100、100C或100D的剖面結構。也就是說，有機發光二極體顯示面板200實質上可具有如圖1B至圖1D所示的任一種剖面結構，故在此省略繪製有機發光二極體顯示面板200的剖面示意圖。It should be noted that although the shape of the organic light emitting diode display panel 200 in FIG. 2 is obviously different from the shape of the organic light emitting diode display panels 100, 100C, and 100D in the foregoing embodiment, the organic light emitting diode display panel 200 The cross-sectional structure of the panel 200 is substantially the same as the cross-sectional structure of the organic light emitting diode display panel 100, 100C, or 100D. In other words, the organic light-emitting diode display panel 200 can substantially have any cross-sectional structure as shown in FIGS. 1B to 1D, so the schematic cross-sectional view of the organic light-emitting diode display panel 200 is omitted here.

此外，第一圍牆240a、第二圍牆240b以及模封層250的剖面結構、構成材料以及形成方法皆相同於前述實施例中的第一圍牆140a（或149a）、第二圍牆140b（或149b）以及模封層150的剖面結構、構成材料以及形成方法，故這裡不再重複贅述。In addition, the cross-sectional structure, constituent materials, and forming method of the first enclosure wall 240a, the second enclosure wall 240b, and the molding layer 250 are the same as those of the first enclosure wall 140a (or 149a) and the second enclosure wall 140b (or 149b) in the foregoing embodiment. As well as the cross-sectional structure, constituent materials, and forming method of the molding layer 150, the details will not be repeated here.

在本發明多個實施例中，有機發光二極體顯示面板的形狀實質上不僅可以是矩形（如圖1A所示的有機發光二極體顯示面板100）或三角形（如圖2所示的有機發光二極體顯示面板200），而且有機發光二極體顯示面板的形狀實質上可以是圓形，如圖3A所示。In many embodiments of the present invention, the shape of the organic light-emitting diode display panel can be substantially not only a rectangle (the organic light-emitting diode display panel 100 shown in FIG. 1A) or a triangle (the organic light-emitting diode display panel 100 shown in FIG. 2). The light emitting diode display panel 200), and the shape of the organic light emitting diode display panel may be substantially circular, as shown in FIG. 3A.

圖3A是本發明另一實施例的有機發光二極體顯示面板的俯視示意圖。請參閱圖3A，不同於前述矩形的有機發光二極體顯示面板100以及三角形的有機發光二極體顯示面板200，圖3A所示的有機發光二極體顯示面板100的形狀實質上為矩形，而有機發光二極體顯示面板300A所包括的控制基板310的邊緣310e可圍繞成圓形。3A is a schematic top view of an organic light emitting diode display panel according to another embodiment of the invention. Referring to FIG. 3A, unlike the rectangular organic light emitting diode display panel 100 and the triangular organic light emitting diode display panel 200, the shape of the organic light emitting diode display panel 100 shown in FIG. 3A is substantially rectangular. The edge 310e of the control substrate 310 included in the organic light emitting diode display panel 300A may be rounded.

有機發光二極體顯示面板300A所包括的第一圍牆340a與第二圍牆340b會沿著邊緣310e而圍繞成圓形，其中第二圍牆340b圍繞第一圍牆340a。此外，有機發光二極體顯示面板300A還包括覆蓋第一圍牆340a、第二圍牆340b與控制基板310的模封層350，其中模封層350具有外邊緣350e，而外邊緣350e也沿著邊緣310e而圍繞成圓形，如圖3A所示。The first wall 340a and the second wall 340b included in the organic light emitting diode display panel 300A are rounded along the edge 310e, and the second wall 340b surrounds the first wall 340a. In addition, the organic light emitting diode display panel 300A further includes a mold sealing layer 350 covering the first enclosure wall 340a, the second enclosure wall 340b and the control substrate 310. The mold sealing layer 350 has an outer edge 350e, and the outer edge 350e is also along the edge. 310e is surrounded into a circle, as shown in FIG. 3A.

圖3B是圖3A中沿線3B-3B剖面而繪示的剖面示意圖。請參閱圖3A與圖3B，與圖1B所示的實施例相似，控制基板310包括元件陣列基板311與絕緣層312。元件陣列基板311的內部結構與前述元件陣列基板111的內部結構實質上相同，即元件陣列基板311也可具有多個開關元件（未繪示）與多個導電層（未繪示），其中元件陣列基板311與111兩者的開關元件與導電層皆可相同。3B is a schematic cross-sectional view along the line 3B-3B in FIG. 3A. Referring to FIGS. 3A and 3B, similar to the embodiment shown in FIG. 1B, the control substrate 310 includes an element array substrate 311 and an insulating layer 312. The internal structure of the element array substrate 311 is substantially the same as the internal structure of the aforementioned element array substrate 111. That is, the element array substrate 311 may also have a plurality of switching elements (not shown) and a plurality of conductive layers (not shown). The switching elements and conductive layers of both the array substrates 311 and 111 can be the same.

元件陣列基板311與111之間的主要差異在於形狀不同，其中元件陣列基板111的形狀為矩形，而元件陣列基板311的形狀為圓形。同樣地，絕緣層312的構成材料可以相同於前述絕緣層112的構成材料，但絕緣層312與112兩者形狀也不相同。絕緣層112的形狀為矩形，而絕緣層312的形狀為圓形。The main difference between the element array substrates 311 and 111 is the shape. The shape of the element array substrate 111 is rectangular, and the shape of the element array substrate 311 is circular. Similarly, the constituent material of the insulating layer 312 may be the same as the constituent material of the aforementioned insulating layer 112, but the shapes of the insulating layers 312 and 112 are different. The shape of the insulating layer 112 is a rectangle, and the shape of the insulating layer 312 is a circle.

控制基板310還具有開口310h，其延伸至控制基板310的相對兩表面。例如，開口310h是從控制基板310的上表面延伸至控制基板310的下表面，如圖3B所示。換句話說，開口310h為貫穿控制基板310而形成的貫孔。另外，開口310h的形狀可為圓形，如圖3A所示。The control substrate 310 also has an opening 310h, which extends to two opposite surfaces of the control substrate 310. For example, the opening 310h extends from the upper surface of the control substrate 310 to the lower surface of the control substrate 310, as shown in FIG. 3B. In other words, the opening 310h is a through hole formed through the control substrate 310. In addition, the shape of the opening 310h may be circular, as shown in FIG. 3A.

控制基板310還具有顯示區A30、第一非顯示區N31與第二非顯示區N32，其中第一非顯示區N31與第二非顯示區N32皆位於顯示區A30外，未與顯示區A30重疊。第一非顯示區N31圍繞顯示區A30與第二非顯示區N32，而第二非顯示區N32圍繞開口310h，並沿著開口310h的邊緣310w而延伸。The control substrate 310 also has a display area A30, a first non-display area N31, and a second non-display area N32. The first non-display area N31 and the second non-display area N32 are both located outside the display area A30 and do not overlap with the display area A30. . The first non-display area N31 surrounds the display area A30 and the second non-display area N32, and the second non-display area N32 surrounds the opening 310h and extends along the edge 310w of the opening 310h.

由於開口310h的形狀為圓形，且控制基板310邊緣310e（外邊緣）圍繞成圓形，因此顯示區A30形狀實質上可以是甜甜圈形，如圖3A所示。開口310h的邊緣310w為控制基板310的內邊緣，因此第二非顯示區N32鄰近控制基板310的內邊緣（邊緣310w），而第一非顯示區N31鄰近控制基板310的外邊緣（邊緣310e）。Since the shape of the opening 310h is a circle, and the edge 310e (outer edge) of the control substrate 310 is surrounded in a circle, the shape of the display area A30 may be substantially a doughnut shape, as shown in FIG. 3A. The edge 310w of the opening 310h is the inner edge of the control substrate 310, so the second non-display area N32 is adjacent to the inner edge (edge 310w) of the control substrate 310, and the first non-display area N31 is adjacent to the outer edge (edge 310e) of the control substrate 310 .

與前述實施例相似，有機發光二極體顯示面板300A也包括平坦層320b、畫素定義層330與多個有機發光二極體160，其中畫素定義層330相似於前述實施例中的畫素定義層130，而畫素定義層130與330之間主要差異在於形狀。具體而言，由於顯示區A30形狀實質上為甜甜圈形，所以畫素定義層330的形狀實質上也是甜甜圈形，以配合顯示區A30的形狀。Similar to the previous embodiment, the organic light emitting diode display panel 300A also includes a flat layer 320b, a pixel defining layer 330, and a plurality of organic light emitting diodes 160, wherein the pixel defining layer 330 is similar to the pixels in the previous embodiment The definition layer 130, and the main difference between the pixel definition layers 130 and 330 lies in the shape. Specifically, since the shape of the display area A30 is substantially a doughnut shape, the shape of the pixel definition layer 330 is also a substantially doughnut shape to match the shape of the display area A30.

平坦層320b相似於圖1C中的平坦層120c。例如，平坦層320b也分布於顯示區A30與第一非顯示區N31，並且也具有圍繞顯示區A30的外圍凹槽321b。不過，與平坦層120c不同的是，平坦層320b更分布於第二非顯示區N32，而且還具有圍繞開口310h的內圍凹槽322b，其中內圍凹槽322b位於第二非顯示區N32內，並沿著開口310h的邊緣310w而延伸。The flat layer 320b is similar to the flat layer 120c in FIG. 1C. For example, the flat layer 320b is also distributed in the display area A30 and the first non-display area N31, and also has a peripheral groove 321b surrounding the display area A30. However, unlike the flat layer 120c, the flat layer 320b is more distributed in the second non-display area N32, and also has an inner groove 322b surrounding the opening 310h, wherein the inner groove 322b is located in the second non-display area N32 , And extend along the edge 310w of the opening 310h.

須說明的是，在圖3B所示的實施例中，平坦層320b具有外圍凹槽321b與內圍凹槽322b，但在其他實施例中，平坦層320b也可以具有外圍凹槽321b與內圍凹槽322b其中一個。例如，平坦層320b可具有外圍凹槽321b，但不具有內圍凹槽322b，以使平坦層320b從顯示區A30延伸至第二非顯示區N32。或者，平坦層320b可具有內圍凹槽322b，但不具有外圍凹槽321b，以使平坦層320b從顯示區A30延伸至第一非顯示區N31。因此，圖3B所示的內圍凹槽322b與外圍凹槽321b僅供舉例說明，並非限制平坦層320b的結構特徵。It should be noted that in the embodiment shown in FIG. 3B, the flat layer 320b has a peripheral groove 321b and an inner groove 322b, but in other embodiments, the flat layer 320b may also have a peripheral groove 321b and an inner groove. One of the grooves 322b. For example, the flat layer 320b may have a peripheral groove 321b but not an inner groove 322b, so that the flat layer 320b extends from the display area A30 to the second non-display area N32. Alternatively, the flat layer 320b may have an inner peripheral groove 322b but not a peripheral groove 321b, so that the flat layer 320b extends from the display area A30 to the first non-display area N31. Therefore, the inner groove 322b and the outer groove 321b shown in FIG. 3B are for illustration only, and do not limit the structural features of the flat layer 320b.

不同於前述實施例的有機發光二極體顯示面板100、100C、100D與200，有機發光二極體顯示面板300A不僅包括第一圍牆340a與第二圍牆340b，而且還包括第三圍牆340c與第四圍牆340d。第三圍牆340c與第四圍牆340d皆設置於第二非顯示區N32內的平坦層320b上，其中第三圍牆340c與第四圍牆340d皆圍繞開口310h，而第三圍牆340c圍繞第四圍牆340d。此外，內圍凹槽322b圍繞第三圍牆340c與第四圍牆340d。Different from the organic light-emitting diode display panels 100, 100C, 100D, and 200 of the foregoing embodiment, the organic light-emitting diode display panel 300A includes not only a first wall 340a and a second wall 340b, but also a third wall 340c and a third wall 340c. Four surrounding walls 340d. The third fence 340c and the fourth fence 340d are both disposed on the flat layer 320b in the second non-display area N32, wherein the third fence 340c and the fourth fence 340d both surround the opening 310h, and the third fence 340c surrounds the fourth fence 340d . In addition, the inner groove 322b surrounds the third wall 340c and the fourth wall 340d.

第三圍牆340c與第四圍牆340d會沿著開口310h的邊緣310w而圍繞成圓形，而圍繞成圓形的第一圍牆340a與第二圍牆340b也圍繞第三圍牆340c與第四圍牆340d，以使第一圍牆340a、第二圍牆340b、第三圍牆340c以及第四圍牆340d可以呈同心圓排列，如圖3A所示。相鄰的第一圍牆340a與第二圍牆340b之間會形成第一溝槽T31，而相鄰的第三圍牆340c與第四圍牆340d之間會形成第二溝槽T32，其中第一溝槽T31與第二溝槽T32皆形成於平坦層320b的上方。此外，第一溝槽T31圍繞第一圍牆340a與顯示區A30，而第二溝槽T32圍繞第四圍牆340d與開口310h。The third fence 340c and the fourth fence 340d surround the edge 310w of the opening 310h into a circle, and the first fence 340a and the second fence 340b that surround the circle also surround the third fence 340c and the fourth fence 340d. In this way, the first enclosure wall 340a, the second enclosure wall 340b, the third enclosure wall 340c, and the fourth enclosure wall 340d can be arranged in concentric circles, as shown in FIG. 3A. A first trench T31 is formed between the adjacent first fence 340a and the second fence 340b, and a second trench T32 is formed between the adjacent third fence 340c and the fourth fence 340d, wherein the first trench Both T31 and the second trench T32 are formed above the flat layer 320b. In addition, the first trench T31 surrounds the first fence 340a and the display area A30, and the second trench T32 surrounds the fourth fence 340d and the opening 310h.

第一溝槽T31的寬度W31可以等於第一溝槽T11的寬度W11（請參考圖1B），所以寬度W31可以介於3微米至100微米之間，但不受此範圍的限制。第二溝槽T32的寬度W32可以相同於第一溝槽T31的寬度W31，所以寬度W32也可介於3微米至100微米之間，但不受此範圍的限制。The width W31 of the first trench T31 may be equal to the width W11 of the first trench T11 (please refer to FIG. 1B), so the width W31 may be between 3 μm and 100 μm, but is not limited by this range. The width W32 of the second trench T32 can be the same as the width W31 of the first trench T31, so the width W32 can also be between 3 microns and 100 microns, but is not limited by this range.

第一圍牆340a具有鄰近顯示區A30的第一壁面S31b，而第二圍牆340b具有遠離顯示區A30的第二壁面S32b。第一壁面S31b與第二壁面S32b皆位在第一溝槽T31外，其中第一溝槽T31圍繞第一壁面S31b，而第二壁面S32b圍繞第一溝槽T31與第一壁面S31b。此外，第一壁面S31b與第二壁面S32b之間的距離341w可以相等於圖1B中的距離140w，所以距離341w可以介於3微米至1000微米之間。The first wall 340a has a first wall surface S31b adjacent to the display area A30, and the second wall 340b has a second wall surface S32b away from the display area A30. The first wall surface S31b and the second wall surface S32b are both located outside the first groove T31, wherein the first groove T31 surrounds the first wall surface S31b, and the second wall surface S32b surrounds the first groove T31 and the first wall surface S31b. In addition, the distance 341w between the first wall surface S31b and the second wall surface S32b may be equal to the distance 140w in FIG. 1B, so the distance 341w may be between 3 micrometers and 1000 micrometers.

相似地，第三圍牆340c具有鄰近顯示區A30的第三壁面S33b，而第四圍牆340d具有遠離顯示區A30的第四壁面S34b。第三壁面S33b與第四壁面S34b皆位在第二溝槽T32外，其中第二溝槽T32圍繞第四壁面S34b，而第三壁面S33b圍繞第二溝槽T32與第四壁面S34b。第三壁面S33b與第四壁面S34b之間的距離342w可以相等於距離341w，所以距離342w可以介於3微米至1000微米之間。Similarly, the third wall 340c has a third wall surface S33b adjacent to the display area A30, and the fourth wall 340d has a fourth wall surface S34b away from the display area A30. The third wall surface S33b and the fourth wall surface S34b are both located outside the second groove T32, wherein the second groove T32 surrounds the fourth wall surface S34b, and the third wall surface S33b surrounds the second groove T32 and the fourth wall surface S34b. The distance 342w between the third wall surface S33b and the fourth wall surface S34b may be equal to the distance 341w, so the distance 342w may be between 3 microns and 1000 microns.

由於距離341w與342w每一者可以介於3微米至1000微米之間，因此第一圍牆340a、第一溝槽T31與第二圍牆340b三者在第一非顯示區N31內佔據較小的面積，而第三圍牆340c、第二溝槽T32與第四圍牆340d三者在第二非顯示區N32內也佔據較小的面積。如此，有機發光二極體顯示面板300A有利於製作成窄邊框型顯示器，以滿足現今窄邊框化的發展趨勢。Since each of the distances 341w and 342w can be between 3 μm and 1000 μm, the first fence 340a, the first trench T31, and the second fence 340b occupy a relatively small area in the first non-display area N31 , And the third fence 340c, the second trench T32, and the fourth fence 340d also occupy a relatively small area in the second non-display area N32. In this way, the organic light emitting diode display panel 300A is beneficial to be manufactured into a narrow-frame display to meet the current development trend of narrow-frame display.

第一圍牆340a、第二圍牆340b、第三圍牆340c以及第四圍牆340d四者的剖面結構可以實質上彼此相同，並且與圖1B所示的第一圍牆140a與第二圍牆140b兩者的剖面結構相似。以圖3B為例，第一圍牆340a包括第一壁體341a與第一頂部342a，第二圍牆340b包括第二壁體341b與第二頂部342b，第三圍牆340c包括第三壁體341c與第三頂部342c，而第四圍牆340d包括第四壁體341d與第四頂部342d。The cross-sectional structures of the first enclosure wall 340a, the second enclosure wall 340b, the third enclosure wall 340c, and the fourth enclosure wall 340d may be substantially the same as each other, and are the same as the cross-sections of the first enclosure wall 140a and the second enclosure wall 140b shown in FIG. 1B The structure is similar. Taking Figure 3B as an example, the first wall 340a includes a first wall 341a and a first top 342a, the second wall 340b includes a second wall 341b and a second top 342b, and the third wall 340c includes a third wall 341c and a first wall 341c. There are three tops 342c, and the fourth wall 340d includes a fourth wall 341d and a fourth top 342d.

第一壁體341a、第二壁體341b、第三壁體341c以及第四壁體341d皆設置於平坦層320b上。第一頂部342a設置於第一壁體341a上方，並沿著第一壁體341a延伸。第二頂部342b設置於第二壁體341b上方，並沿著第二壁體341b延伸。第三頂部342c設置於第三壁體341c上方，並沿著第三壁體341c延伸。第四頂部342d設置於第四壁體341d上方，並沿著第四壁體341d延伸。The first wall 341a, the second wall 341b, the third wall 341c, and the fourth wall 341d are all disposed on the flat layer 320b. The first top portion 342a is disposed above the first wall 341a and extends along the first wall 341a. The second top portion 342b is disposed above the second wall 341b and extends along the second wall 341b. The third top portion 342c is disposed above the third wall 341c and extends along the third wall 341c. The fourth top 342d is disposed above the fourth wall 341d and extends along the fourth wall 341d.

第一壁體341a、第二壁體341b、第三壁體341c以及第四壁體341d四者的構成材料與形成方法可以彼此相同。例如，第一壁體341a、第二壁體341b、第三壁體341c、第四壁體341d以及畫素定義層330可以由同一層光阻經曝光與顯影之後而形成。同理，第一頂部342a、第二頂部342b、第三頂部342c與第四頂部342d也可由同一層光阻經曝光與顯影之後而形成，所以第一頂部342a、第二頂部342b、第三頂部342c與第四頂部342d四者的構成材料與形成方法可以彼此相同。The constituent materials and forming methods of the first wall 341a, the second wall 341b, the third wall 341c, and the fourth wall 341d may be the same as each other. For example, the first wall 341a, the second wall 341b, the third wall 341c, the fourth wall 341d, and the pixel definition layer 330 can be formed by the same layer of photoresist after exposure and development. In the same way, the first top 342a, the second top 342b, the third top 342c, and the fourth top 342d can also be formed by the same layer of photoresist after exposure and development, so the first top 342a, the second top 342b, and the third top The constituent materials and forming methods of the 342c and the fourth top 342d may be the same as each other.

圖3B中的模封層350與圖1B中的模封層150相似，而模封層350也包括有機密封層351與無機密封層352，其中有機密封層351的構成材料與形成方法皆相同於有機密封層151的構成材料與形成方法，而無機密封層352的構成材料與形成方法皆相同於無機密封層152的構成材料與形成方法，故在此不再重複贅述。The mold sealing layer 350 in FIG. 3B is similar to the mold sealing layer 150 in FIG. 1B, and the mold sealing layer 350 also includes an organic sealing layer 351 and an inorganic sealing layer 352, wherein the organic sealing layer 351 is composed of the same material and forming method as The constituent material and forming method of the organic sealing layer 151, and the constituent material and forming method of the inorganic sealing layer 352 are the same as the constituent material and forming method of the inorganic sealing layer 152, so they will not be repeated here.

有機密封層351設置於平坦層320b上，並分布於顯示區A30，其中有機密封層351填滿外圍凹槽321b與內圍凹槽322b。無機密封層352設置於控制基板310上，並且覆蓋有機密封層351、第一圍牆340a、第二圍牆340b、第三圍牆340c與第四圍牆340d，其中無機密封層352更可以填滿第一溝槽T31與第二溝槽T32。The organic sealing layer 351 is disposed on the flat layer 320b and distributed in the display area A30. The organic sealing layer 351 fills the outer groove 321b and the inner groove 322b. The inorganic sealing layer 352 is disposed on the control substrate 310 and covers the organic sealing layer 351, the first wall 340a, the second wall 340b, the third wall 340c, and the fourth wall 340d. The inorganic sealing layer 352 can even fill the first groove. The groove T31 and the second groove T32.

有機發光二極體顯示面板300A可以應用於穿戴裝置或設備的儀表板。例如，有機發光二極體顯示面板300A可應用於手錶，其中開口310h可位於有機發光二極體顯示面板300A的中央，而用於轉動指針的轉軸可設置在開口310h內。或者，有機發光二極體顯示面板300A可應用於車輛的儀表板，其中開口310h可位於有機發光二極體顯示面板300A的中央或中央偏下的位置，而用於轉動儀表板指針的轉軸可設置在開口310h內。The organic light emitting diode display panel 300A may be applied to the dashboard of a wearable device or equipment. For example, the organic light-emitting diode display panel 300A may be applied to a watch, wherein the opening 310h may be located in the center of the organic light-emitting diode display panel 300A, and the rotating shaft for rotating the pointer may be provided in the opening 310h. Alternatively, the organic light-emitting diode display panel 300A can be applied to the dashboard of a vehicle, wherein the opening 310h can be located at the center or a position lower than the center of the organic light-emitting diode display panel 300A, and the shaft for rotating the pointer of the dashboard can be Set in the opening 310h.

特別一提的是，雖然圖3A僅繪示一個開口310h、一個第三圍牆340c以及一個第四圍牆340d，但在其他實施例中，控制基板310可以具有至少兩個開口310h與至少兩個第二非顯示區N32，而各個開口310h周圍設置兩道圍牆：第三圍牆340c與第四圍牆340d。因此，控制基板310可以具有多個開口310h，而有機發光二極體顯示面板300A可包括多個第三圍牆340c以及多個第四圍牆340d，以分別圍繞這些開口310h。In particular, although FIG. 3A only shows one opening 310h, one third wall 340c, and one fourth wall 340d, in other embodiments, the control substrate 310 may have at least two openings 310h and at least two second walls. The second non-display area N32, and each opening 310h is surrounded by two fences: a third fence 340c and a fourth fence 340d. Therefore, the control substrate 310 may have a plurality of openings 310h, and the organic light emitting diode display panel 300A may include a plurality of third walls 340c and a plurality of fourth walls 340d to respectively surround the openings 310h.

其次，雖然圖3A所示的開口310h的形狀為圓形，但在其他實施例中，開口310h可以是圓形以外的其他形狀，例如矩形、三角形、五邊形、六邊形、星形或心形，因此圖3A所示的開口310h的形狀僅供舉例說明，並非限制只能是圓形。Secondly, although the shape of the opening 310h shown in FIG. 3A is a circle, in other embodiments, the opening 310h may be a shape other than a circle, such as a rectangle, a triangle, a pentagon, a hexagon, a star, or Heart shape, therefore, the shape of the opening 310h shown in FIG. 3A is for illustration only, and it is not limited to being circular.

圖3C是本發明至少一實施例的有機發光二極體顯示面板的剖面示意圖。請參閱圖3C，本實施例的有機發光二極體顯示面板300B與前述實施例的有機發光二極體顯示面板300A相似，其中有機發光二極體顯示面板300B與300A兩者的俯視外觀實質上可以彼此相同，如圖3A所示。因此，這裡省略繪製有機發光二極體顯示面板300B的俯視示意圖，而有機發光二極體顯示面板300B與300A兩者相同特徵原則上不再重複贅述。3C is a schematic cross-sectional view of an organic light emitting diode display panel according to at least one embodiment of the invention. Referring to FIG. 3C, the organic light emitting diode display panel 300B of this embodiment is similar to the organic light emitting diode display panel 300A of the previous embodiment, and the top view appearances of both the organic light emitting diode display panels 300B and 300A are substantially They can be the same as each other, as shown in Figure 3A. Therefore, drawing the schematic top view of the organic light emitting diode display panel 300B is omitted here, and the same features of the organic light emitting diode display panels 300B and 300A are not repeated in principle.

有別於前述有機發光二極體顯示面板300A，有機發光二極體顯示面板300B所包括的平坦層320c不同於平坦層320b。具體而言，平坦層320c不僅從顯示區A30沿著控制基板310的上表面310u而延伸至第一非顯示區N31，而且還從顯示區A30沿著上表面310u而延伸至第二非顯示區N32。因此，平坦層320c並不具有外圍凹槽321b與內圍凹槽322b。Different from the aforementioned organic light emitting diode display panel 300A, the organic light emitting diode display panel 300B includes a flat layer 320c different from the flat layer 320b. Specifically, the flat layer 320c not only extends from the display area A30 to the first non-display area N31 along the upper surface 310u of the control substrate 310, but also extends from the display area A30 to the second non-display area along the upper surface 310u. N32. Therefore, the flat layer 320c does not have the outer groove 321b and the inner groove 322b.

其次，有機發光二極體顯示面板300B還包括兩個墊層370a與370b、第一圍牆349a、第二圍牆349b、第三圍牆349c與第四圍牆349d。墊層370a與370b皆位於平坦層320c上，其中墊層370a設置於第一非顯示區N31內，而墊層370b設置於第二非顯示區N32內。第一圍牆349a以及第二圍牆349b皆設置於墊層370a上，而位於第一圍牆349a與第二圍牆349b之間的第一溝槽T41形成於墊層370a的上方。第三圍牆349c以及第四圍牆349d設置於墊層370b上，而位於第三圍牆349c與第四圍牆349d之間的第二溝槽T42形成於墊層370b的上方。Secondly, the organic light emitting diode display panel 300B further includes two cushion layers 370a and 370b, a first wall 349a, a second wall 349b, a third wall 349c, and a fourth wall 349d. The cushion layers 370a and 370b are both located on the flat layer 320c, wherein the cushion layer 370a is disposed in the first non-display area N31, and the cushion layer 370b is disposed in the second non-display area N32. The first fence 349a and the second fence 349b are both disposed on the cushion layer 370a, and the first trench T41 between the first fence 349a and the second fence 349b is formed above the cushion layer 370a. The third fence 349c and the fourth fence 349d are disposed on the cushion layer 370b, and the second trench T42 between the third fence 349c and the fourth fence 349d is formed above the cushion layer 370b.

墊層370a、370b與畫素定義層330可以由同一層光阻經曝光與顯影之後而形成，所以墊層370a、370b與畫素定義層330三者厚度實質上彼此相同。第一圍牆349a、第二圍牆349b、第三圍牆349c與第四圍牆349d的構成材料與形成方法皆可相同於圖3B中的第一頂部342a、第二頂部342b、第三頂部342c與第四頂部342d的構成材料與形成方法，因此第一圍牆349a、第二圍牆349b、第三圍牆349c與第四圍牆349d可以由同一層光阻經曝光與顯影之後而形成。The cushion layers 370a, 370b and the pixel definition layer 330 can be formed by the same layer of photoresist after exposure and development. Therefore, the thickness of the cushion layers 370a, 370b and the pixel definition layer 330 are substantially the same as each other. The constituent materials and forming methods of the first enclosure wall 349a, the second enclosure wall 349b, the third enclosure wall 349c, and the fourth enclosure wall 349d can all be the same as the first top 342a, the second top 342b, the third top 342c, and the fourth top in FIG. 3B. The material and forming method of the top 342d, so the first wall 349a, the second wall 349b, the third wall 349c, and the fourth wall 349d can be formed by the same layer of photoresist after exposure and development.

第一圍牆349a具有鄰近顯示區A30的第一壁面S31c，而第二圍牆349b具有遠離顯示區A30的第二壁面S32c。第一壁面S31c與第二壁面S32c皆位在第一溝槽T41外，其中第一溝槽T41圍繞第一壁面S31c，而第二壁面S32c圍繞第一溝槽T41與第一壁面S31c。此外，第一壁面S31c與第二壁面S32c之間的距離343w可以相等於圖3B中的距離341w，所以距離343w可以介於3微米至1000微米之間。The first enclosure wall 349a has a first wall surface S31c adjacent to the display area A30, and the second enclosure wall 349b has a second wall surface S32c away from the display area A30. The first wall surface S31c and the second wall surface S32c are both located outside the first groove T41, wherein the first groove T41 surrounds the first wall surface S31c, and the second wall surface S32c surrounds the first groove T41 and the first wall surface S31c. In addition, the distance 343w between the first wall surface S31c and the second wall surface S32c may be equal to the distance 341w in FIG. 3B, so the distance 343w may be between 3 micrometers and 1000 micrometers.

相似地，第三圍牆349c具有鄰近顯示區A30的第三壁面S33c，而第四圍牆349d具有遠離顯示區A30的第四壁面S34c。第三壁面S33c與第四壁面S34c皆位在第二溝槽T42外，其中第二溝槽T42圍繞第四壁面S34c，而第三壁面S33c圍繞第二溝槽T42與第四壁面S34c。第三壁面S33c與第四壁面S34c之間的距離344w可相等於距離343w，所以距離344w可介於3微米至1000微米之間。如此，有機發光二極體顯示面板300B有利於製作成窄邊框型顯示器，以滿足現今窄邊框化的發展趨勢。Similarly, the third wall 349c has a third wall surface S33c adjacent to the display area A30, and the fourth wall 349d has a fourth wall surface S34c away from the display area A30. The third wall surface S33c and the fourth wall surface S34c are both located outside the second groove T42, wherein the second groove T42 surrounds the fourth wall surface S34c, and the third wall surface S33c surrounds the second groove T42 and the fourth wall surface S34c. The distance 344w between the third wall surface S33c and the fourth wall surface S34c may be equal to the distance 343w, so the distance 344w may be between 3 micrometers and 1000 micrometers. In this way, the organic light-emitting diode display panel 300B is advantageous for manufacturing a narrow-frame display to meet the current development trend of narrow-frame display.

特別一提的是，在圖3C所示的實施例中，有機發光二極體顯示面板300B的平坦層320c可替換成圖3B中的平坦層320b，所以圖3C中的平坦層320c可具有外圍凹槽321b與內圍凹槽322b。此外，圖3C中的平坦層320c可具有外圍凹槽321b與內圍凹槽322b其中一者。也就是說，平坦層320c可具有外圍凹槽321b，但不具有內圍凹槽322b。或是，平坦層320c可具有內圍凹槽322b，但不具有外圍凹槽321b。In particular, in the embodiment shown in FIG. 3C, the flat layer 320c of the organic light emitting diode display panel 300B can be replaced with the flat layer 320b in FIG. 3B, so the flat layer 320c in FIG. 3C may have a periphery The groove 321b and the inner groove 322b. In addition, the flat layer 320c in FIG. 3C may have one of a peripheral groove 321b and an inner peripheral groove 322b. That is, the flat layer 320c may have the peripheral groove 321b but not the inner groove 322b. Alternatively, the flat layer 320c may have an inner groove 322b but not a peripheral groove 321b.

另外，圖3C中的第一圍牆349a、第二圍牆349b、第三圍牆349c、第四圍牆349d、墊層370a與370b可替換成圖3B中的第一圍牆340a、第二圍牆340b、第三圍牆340c與第四圍牆340d。所以，圖3B中的第一圍牆340a、第二圍牆340b、第三圍牆340c與第四圍牆340d也可設置在圖3C中的平坦層320c上。In addition, the first fence 349a, the second fence 349b, the third fence 349c, the fourth fence 349d, the cushion layers 370a and 370b in FIG. 3C can be replaced with the first fence 340a, the second fence 340b, and the third fence in FIG. 3B. The fence 340c and the fourth fence 340d. Therefore, the first enclosure wall 340a, the second enclosure wall 340b, the third enclosure wall 340c, and the fourth enclosure wall 340d in FIG. 3B can also be arranged on the flat layer 320c in FIG. 3C.

綜上所述，上述多道圍牆（例如第一圍牆與第二圍牆）以及模封層能阻礙及阻擋外界氧氣與水氣滲入，以保護顯示區內的多個有機發光二極體免於遭受氧氣及/或水氣破壞，進而提升有機發光二極體顯示面板的使用壽命。In summary, the above-mentioned multiple enclosure walls (such as the first enclosure wall and the second enclosure wall) and the mold sealing layer can hinder and block the infiltration of external oxygen and water vapor, so as to protect the multiple organic light-emitting diodes in the display area from suffering Oxygen and/or moisture damage, thereby increasing the service life of the organic light emitting diode display panel.
