Description
本揭露是有關於一種顯示面板。 The disclosure relates to a display panel.
因應行動裝置面板的發展趨勢，目前顯示面板的解析度(Resolution)和畫素密度(Pixels per inch；PPI)都愈來愈高。由於畫素密度愈來愈高，導致每個子畫素(Sub pixel)的尺寸愈來愈小。然而子畫素中主動元件的尺寸無法因應子畫素縮小而微縮的情況之下，會導致子畫素中的透光區域下降，進而使得面板的開口率(Aperture ratio；AR)下降，而開口率下降會導致面板的穿透率下降，進而嚴重影響顯示器的亮度。 In response to the trend of mobile device panels, the resolution and pixel density (PPI) of display panels are increasing. As the pixel density becomes higher and higher, the size of each subpixel is getting smaller and smaller. However, in the case where the size of the active component in the sub-pixel cannot be reduced in accordance with the reduction of the sub-pixel, the light-transmitting region in the sub-pixel is lowered, and the aperture ratio (AR) of the panel is lowered, and the opening is opened. A drop in the rate will result in a decrease in the transmittance of the panel, which in turn will seriously affect the brightness of the display.
在降低面板開口率的因素中，其中一個具有代表性的因素就是黑色矩陣圓角(Black matrix rounding；BM rounding)對面板開口率所帶來的衝擊。在黑色矩陣的微影製程(Photolithography process)時，由於光學繞射和製程限制，會導致黑色矩陣於圖案化後在開口區域的角落無法形成直角，而會在開口區域的角落形成圓角區域(Rounding area)。當有圓角區域形成時，會降低開口率。當畫素密度提高時，黑色矩陣圓角區域占開口區域的比例會 愈來愈高，進而降低面板開口率。 Among the factors that reduce the panel aperture ratio, one of the representative factors is the impact of the black matrix rounding (BM rounding) on the panel aperture ratio. In the black matrix photolithography process, due to optical diffraction and process limitations, the black matrix cannot form a right angle at the corner of the open area after patterning, and a rounded area is formed at the corner of the open area ( Rounding area). When a rounded area is formed, the aperture ratio is lowered. When the pixel density is increased, the ratio of the black matrix fillet area to the open area will Increasingly higher, which in turn reduces the panel opening rate.
先前技術解決圓角區域的方式，是利用光罩及曝光補償的方式來降低圓角區域的影響，透過光學模擬來決定補償的範圍和程度。然而此種解決方式常因黑色矩陣材料與製程的限制，使得光學模擬的結果與實際產品有相當大的差異，因此需要透過不斷的模擬及試作，以確認符合產品設計的規格。這個過程需要耗費大量的成本及時間。因此，如何有效的降低成本及時間，實為一重要的課題。 The prior art solves the rounded area by using a mask and exposure compensation to reduce the effect of the fillet area, and optical simulation to determine the extent and extent of compensation. However, such a solution is often limited by the limitations of the black matrix material and the process, so that the results of the optical simulation are quite different from the actual products. Therefore, it is necessary to confirm the specifications of the product design through continuous simulation and trial production. This process requires a lot of cost and time. Therefore, how to effectively reduce costs and time is an important issue.

以下將以圖式揭露本發明之複數個實施方式，為明確說明起見，許多實務上的細節將在以下敘述中一併說明。然而，應瞭解到，這些實務上的細節不應用以限制本發明。也就是說，在本發明部分實施方式中，這些實務上的細節是非必要的。此外，為簡化圖式起見，一些習知慣用的結構與元件在圖式中將以簡單示意的方式繪示之。 The embodiments of the present invention are disclosed in the following drawings, and the details of However, it should be understood that these practical details are not intended to limit the invention.

第1圖繪示依照本發明一實施方式之顯示面板100的局部俯視圖。第2圖繪示沿第1圖之線段2-2的剖面圖。如第1~2圖所示，顯示面板100包括主動元件陣列基板110、複數個子畫素120、黑色矩陣圖案130、遮光金屬層、對向基板140與顯示介質150。子畫素120設置於主動元件陣列基板110上。對向基板140相對主動元件陣列基板110設置。顯示介質150設置於主動元件陣列基板110與對向基板140之間。 FIG. 1 is a partial plan view of a display panel 100 in accordance with an embodiment of the present invention. Figure 2 is a cross-sectional view taken along line 2-2 of Figure 1. As shown in FIGS. 1 to 2, the display panel 100 includes an active device array substrate 110, a plurality of sub-pixels 120, a black matrix pattern 130, a light-shielding metal layer, a counter substrate 140, and a display medium 150. The sub-pixel 120 is disposed on the active device array substrate 110. The opposite substrate 140 is disposed relative to the active device array substrate 110. The display medium 150 is disposed between the active device array substrate 110 and the opposite substrate 140.
在本實施方式中，每一子畫素120包括切換元件122與畫素電極124，畫素電極124電性連接切換元件122。黑色矩陣圖案130位於對向基板140並具有複數個開口區域O，每一開口區域O與每一畫素電極124至少部分相對應，使得穿過受畫素電極124影響之顯示介質150的光線，能夠進一步穿過開口區域O，而顯示各子畫素120對應的畫素資料。 In the present embodiment, each sub-pixel 120 includes a switching element 122 and a pixel electrode 124, and the pixel electrode 124 is electrically connected to the switching element 122. The black matrix pattern 130 is located on the opposite substrate 140 and has a plurality of opening regions O, each of the opening regions O correspondingly at least partially corresponding to each of the pixel electrodes 124 such that the light passing through the display medium 150 affected by the pixel electrodes 124 is It is possible to further pass through the opening area O and display the pixel data corresponding to each sub-pixel 120.
在本實施方式中，顯示面板100另包括掃描線126與數據線128位於主動元件陣列基板110上，而上述之切換元件122可為薄膜電晶體。更具體地說，上述之切換元 件122可包括閘極G、閘介電層GI、通道層C、源極S與汲極D。閘極G電性連接掃描線126。閘介電層GI至少部分位於閘極G與通道層C之間。源極S與汲極D位於通道層C的兩側。源極S電性連接數據線128。畫素電極124電性連接汲極D。應了解到，雖然本實施方式將切換元件122繪示為底閘型薄膜電晶體，但此並不限制本發明，實際上切換元件122亦可為其他形式的主動元件，例如頂閘型薄膜電晶體，本發明所屬技術領域中具有通常知識者，應視實際需要，彈性選擇切換元件122的實施方式。 In the embodiment, the display panel 100 further includes a scan line 126 and a data line 128 on the active device array substrate 110, and the switching element 122 may be a thin film transistor. More specifically, the above switching element The device 122 can include a gate G, a gate dielectric layer GI, a channel layer C, a source S, and a drain D. The gate G is electrically connected to the scan line 126. The gate dielectric layer GI is at least partially located between the gate G and the channel layer C. The source S and the drain D are located on both sides of the channel layer C. The source S is electrically connected to the data line 128. The pixel electrode 124 is electrically connected to the drain D. It should be understood that although the switching element 122 is illustrated as a bottom gate type thin film transistor, the present invention does not limit the present invention. In fact, the switching element 122 may also be other types of active components, such as a top gate type thin film. Crystals, which are generally known in the art to which the present invention pertains, should be flexibly selected for implementation of the switching element 122, depending on actual needs.
本實施方式之黑色矩陣圖案130包含本體部132以及與本體部132不相連的複數個島部134，島部134與前述數據線128具有實質相同的長度延伸方向(如雙箭頭LD所標示)，並分別與對應的數據線128部分重疊。由於先前技術的黑色矩陣圖案在經過圖案化製程後，所形成的圓角(Rounding)區域佔開口區域的比例過高，因此本實施方式將黑色矩陣圖案130斷開為本體部132與島部134。由於黑色矩陣圖案130被斷開為本體部132與島部134，因此在製程中，黑色矩陣圖案130可以被過度曝光(over dosing)或過度蝕刻(over etching)，讓後續黑色矩陣圖案130的圓角區域R可大幅減少，並讓開口區域O的面積增加，進而提升顯示面板100的開口率。 The black matrix pattern 130 of the present embodiment includes a body portion 132 and a plurality of island portions 134 that are not connected to the body portion 132. The island portion 134 and the data line 128 have substantially the same length extension direction (as indicated by the double arrow LD). And partially overlapping with the corresponding data line 128, respectively. Since the ratio of the rounded area formed by the prior art black matrix pattern to the open area is too high after the patterning process, the black matrix pattern 130 is broken into the body portion 132 and the island portion 134 in the present embodiment. . Since the black matrix pattern 130 is broken into the body portion 132 and the island portion 134, the black matrix pattern 130 may be over-dosed or over-etched in the process to make the circle of the subsequent black matrix pattern 130 The corner area R can be greatly reduced, and the area of the opening area O is increased, thereby increasing the aperture ratio of the display panel 100.
但是，由於本體部132與島部134分開，因此本體部132與島部134之間會存在斷開區域L。從另一個角度來看，由於斷開區域L會連通兩相鄰的開口區域O，所以斷 開區域L也可以被視為連通兩相鄰之開口區域O的連通區域。由於斷開區域L會漏光，因此為了防止斷開區域L漏光，本實施方式進一步利用遮光金屬層來遮蔽斷開區域L。在本實施方式中，數據線128可應用來作為遮光金屬層。更具體的說，數據線128在主動元件陣列基板110上的正投影I1，會與斷開區域L在主動元件陣列基板110上的正投影I2至少部分重疊，以避免光線透過斷開區域L漏光。 However, since the body portion 132 is separated from the island portion 134, there is a disconnected region L between the body portion 132 and the island portion 134. From another point of view, since the disconnected region L will connect two adjacent open regions O, The open area L can also be regarded as a connected area that connects two adjacent open areas O. Since the disconnection region L leaks light, in order to prevent light leakage in the disconnection region L, the present embodiment further shields the disconnection region L by the light shielding metal layer. In the present embodiment, the data line 128 can be applied as a light-shielding metal layer. More specifically, the orthographic projection I1 of the data line 128 on the active device array substrate 110 at least partially overlaps with the orthographic projection I2 of the broken region L on the active device array substrate 110 to prevent light from leaking through the disconnected region L. .
在本實施方式中，遮光金屬層的寬度可大於或等於島部134的寬度WI。更具體地說，數據線128具有一部分P與斷開區域L重疊，且此部分P的寬度WP可大於或等於島部134的寬度WI，以完整遮蔽斷開區域L。至於數據線128的其他部分，例如與本體部132重疊的部分，若是考慮到製程上線寬與線距的限制，則其寬度可小於部分P的寬度WP。 In the present embodiment, the width of the light shielding metal layer may be greater than or equal to the width WI of the island portion 134. More specifically, the data line 128 has a portion P overlapping the broken region L, and the width WP of this portion P may be greater than or equal to the width WI of the island portion 134 to completely shield the broken region L. As for the other portions of the data line 128, for example, the portion overlapping the body portion 132, the width may be smaller than the width WP of the portion P in consideration of the limitation of the line width and the line pitch on the process.
在本實施方式中，單一數據線128將一併遮蔽複數個斷開區域L。或者說，單一數據線128可一併與複數個斷開區域L重疊。如第2圖所繪示，複數個斷開區域L在主動元件陣列基板110上的正投影I2，會與單一數據線128在主動元件陣列基板110上的正投影I1至少部分重疊。 In the present embodiment, a single data line 128 will collectively shield a plurality of disconnected regions L. Alternatively, the single data line 128 may overlap with a plurality of disconnected regions L. As shown in FIG. 2, the orthographic projection I2 of the plurality of disconnected regions L on the active device array substrate 110 at least partially overlaps with the orthographic projection I1 of the single data line 128 on the active device array substrate 110.
在本實施方式中，本體部132至少與掃描線126以及切換元件122重疊，以遮蔽切換元件122。島部134至少與數據線128部分重疊，且島部134的長度延伸方向(如雙箭頭LD所標示)可與數據線128的長度延伸方向(如雙箭頭LD所標示)大致平行。但此不並限制本發明，實際上黑色矩陣圖案130也可以是其他形狀，只要存在斷開區域L即可。 In the present embodiment, the body portion 132 overlaps at least the scanning line 126 and the switching element 122 to shield the switching element 122. The island portion 134 at least partially overlaps the data line 128, and the length extension direction of the island portion 134 (as indicated by the double arrow LD) may be substantially parallel to the length extension direction of the data line 128 (as indicated by the double arrow LD). However, this does not limit the present invention. Actually, the black matrix pattern 130 may have other shapes as long as the disconnection region L exists.
