Similarly, the first mirror having a second axis MA1 and the angle θ 2 between the second extension shaft EX2, a second angle θ 2 of between 18 ° ~ 72 °, and the second angle θ 2 is equal to the first angle θ 1 .
第一子畫素141與第二子畫素142中最接近的第一發光 元件L11與第二發光元件L21之間相距第一間距S1,且第一距離H1大於第一間距S1。換言之,第一子畫素141中最接近第二子畫素142中第二發光元件L21的第一發光元件L11與最接近第二子畫素142中第二發光元件L21之間的距離(第一間距S1)小於同一第一子畫素141內的兩第一發光元件L11、L12之間的距離(第一距離H1)。同理,第二距離H2大於第一間距S1。需說明的是,發光元件之間的距離及間距(例如是第一距離H1、第二距離H2、第一間距S1、第二間距S2等)之定義係指自一發光元件至另一發光元件之間的最短距離,例如是自一發光元件的邊緣或表面至另一發光元件的邊緣或表面之間的間距。 The first luminescence of the first sub-pixel 141 and the second sub-pixel 142 that are closest The element L11 and the second light emitting element L21 are separated by a first distance S1, and the first distance H1 is greater than the first distance S1. In other words, the distance between the first light-emitting element L11 closest to the second light-emitting element L21 in the second sub-pixel 142 and the second light-emitting element L21 closest to the second sub-pixel 142 (the first A distance S1) is smaller than the distance between the first light-emitting elements L11 and L12 in the same first sub-pixel 141 (first distance H1). Similarly, the second distance H2 is greater than the first distance S1. It should be noted that the definition of the distance and spacing between the light emitting elements (such as the first distance H1, the second distance H2, the first distance S1, the second distance S2, etc.) refers to from one light emitting element to another The shortest distance between them is, for example, the distance from the edge or surface of one light-emitting element to the edge or surface of another light-emitting element.
於此,對同一子畫素140來說,此些發光元件位於此畫素區域P的不相鄰的角落,且子畫素140中至少一發光元件與相鄰的子畫素140中至少一發光元件最接近,使得分別位於相鄰的畫素區域P的最相鄰的發光元件之間的距離相較於位於同一畫素區域P內的相鄰的發光元件之間的距離來得近,進而分別位於相鄰的畫素區域P的相鄰的發光元件的出光混色更均勻,且倘使製程變異時的色偏影響或雲狀條紋也可以因此設計而更為減緩。 Here, for the same sub-pixel 140, the light-emitting elements are located at non-adjacent corners of the pixel area P, and at least one of the light-emitting elements in the sub-pixel 140 and at least one of the adjacent sub-pixels 140 The light emitting elements are closest to each other, so that the distance between the nearest neighboring light emitting elements located in adjacent pixel regions P is closer than the distance between adjacent light emitting elements located in the same pixel region P, and The light emission and color mixing of the adjacent light-emitting elements located in the adjacent pixel regions P are more uniform, and if the color variation effect or the cloud-like stripes when the manufacturing process is changed, the design can be more slowed down.
於一實施例中,第一畫素區域P1的第一邊緣D1與第三邊緣D3相連以形成此些第一角落A1其中之一,且第一邊緣D1與第三邊緣D3之長度的比例介於1至2。於此,相較於習知畫素區域的短邊緣與長邊緣之間的比例來說,本發明之第一畫素區域P1的第一邊緣D1與第三邊緣D3之間的比例較小,亦即,本發明之第一畫素區域P1的 第一邊緣D1與第三邊緣D3之間的長度差異較小。因此,分別位於相鄰的畫素區域P的最相鄰的發光元件之間的距離更佳地較於位於同一畫素區域P內的相鄰的發光元件之間的距離來得近,使得分別位於相鄰的畫素區域P的相鄰的發光元件的出光混色更佳地均勻,且倘使製程變異時的色偏影響或雲狀條紋也可以因此設計更為減緩。 In one embodiment, the first edge D1 and the third edge D3 of the first pixel area P1 are connected to form one of the first corners A1, and the ratio of the length of the first edge D1 and the third edge D3 is From 1 to 2. Here, compared with the ratio between the short edge and the long edge of the conventional pixel area, the ratio between the first edge D1 and the third edge D3 of the first pixel area P1 of the present invention is smaller, That is, the first pixel area P1 of the present invention The difference in length between the first edge D1 and the third edge D3 is small. Therefore, the distance between the nearest neighboring light-emitting elements in the adjacent pixel regions P is better than the distance between adjacent light-emitting elements in the same pixel region P, so that The light emission and color mixing of the adjacent light-emitting elements in the adjacent pixel area P are more uniform, and the color shift effect or cloud stripes when the manufacturing process is changed can also be designed to be slower.
於另一實施態樣中,當第一邊緣D1與第三邊緣D3之長度的比例介於1至2時,第一夾角θ1大於等於26°且小於等於63°。第二夾角θ2與第一夾角θ1相等,因此第二夾角θ2亦可以是大於等於26°且小於等於63°。於此,發光元件的配置在此角度範圍內的設計尤佳,空間使用上亦具備優勢,更可達到相鄰的畫素區域P的相鄰的發光元件的出光混色更佳地均勻,且倘使製程變異時的色偏影響或雲狀條紋更為減緩。 In another embodiment, when the ratio of the length of the first edge D1 and the third edge D3 is between 1 and 2, the first included angle θ 1 is greater than or equal to 26 ° and less than or equal to 63 °. The second included angle θ 2 is equal to the first included angle θ 1 , so the second included angle θ 2 may also be 26 ° or more and 63 ° or less. Here, the design of the arrangement of the light-emitting elements in this angle range is better, and the space is also advantageous, and the light mixing of the adjacent light-emitting elements of the adjacent pixel area P can be more uniformly uniform, and if The influence of color shift or cloud stripes when the process is mutated is more slowed down.
因應位於畫素區域P內的發光元件的排列方式,各子畫素的電路元件亦可以具有不同的配置方式。於一實施例中,如圖1所繪示,第一子畫素141可以包括一第一電路元件E1。對基板110的垂直投影上,第一電路元件E1位於第一畫素區域P1內之此些第一發光元件L1之間。由於此些第一發光元件L1位於第一畫素區域P1的複數個第一角落A1上,因此第一畫素區域P1的中心空間可用以設置第一電路元件E1。於此,第一畫素區域P1的空間利用率提高,同時亦減少將線路或電性元件配置於第一畫素區域P1之外的情況。於一實施態樣中,如圖1所繪示,第一電路元件E1未與此些第一發光元件L1重疊。於另一實施態樣(未繪示)中,第一電路元件E1可部分地與 至少其中之一第一發光元件L1重疊。於一實施態樣(未繪示)中,第一電路元件E1與此些第一發光元件L1電性連接以提供電源或其他訊號。第一電路元件E1可以是但不限於一個或複數個薄膜電晶體、電容、晶片、走線、導孔及/或其他線路或電性元件等。 Depending on the arrangement of the light-emitting elements in the pixel area P, the circuit elements of each sub-pixel may also have different arrangements. In one embodiment, as shown in FIG. 1, the first sub-pixel 141 may include a first circuit element E1. In the vertical projection of the substrate 110, the first circuit element E1 is located between the first light-emitting elements L1 in the first pixel area P1. Since these first light-emitting elements L1 are located on the plurality of first corners A1 of the first pixel area P1, the central space of the first pixel area P1 can be used to set the first circuit element E1. Here, the space utilization rate of the first pixel area P1 is improved, and at the same time, the situation that lines or electrical elements are arranged outside the first pixel area P1 is reduced. In one embodiment, as shown in FIG. 1, the first circuit element E1 does not overlap with the first light-emitting elements L1. In another embodiment (not shown), the first circuit element E1 may be partially At least one of the first light emitting elements L1 overlaps. In an embodiment (not shown), the first circuit element E1 and the first light-emitting elements L1 are electrically connected to provide power or other signals. The first circuit element E1 may be, but not limited to, one or more thin film transistors, capacitors, chips, traces, vias, and / or other wiring or electrical elements.
於另一實施例中,如圖1所繪示,第二子畫素142可以包括第二電路元件E2。對基板110的垂直投影上,第二電路元件E2位於第二畫素區域P2內之此些第二發光元件L2之間。由於此些第二發光元件L2位於第二畫素區域P2的複數個第二角落A2上,因此第二畫素區域P2的中心空間可用以設置第一電路元件E1。於此,第二畫素區域P2的空間利用率提高,同時亦減少將線路或電性元件配置於第二畫素區域P2之外的情況。於一實施態樣中,如圖1所繪示,第二電路元件E2未與此些第二發光元件L2重疊。於另一實施態樣(未繪示)中,第二電路元件E2可部分地與至少其中之一第二發光元件L2重疊。於一實施態樣中,第二電路元件E2與此些第二發光元件L2電性連接以提供電源或其他訊號。第二電路元件E2可以是但不限於一個或複數個薄膜電晶體、電容、晶片、走線、導孔及/或其他線路或電性元件等。 In another embodiment, as shown in FIG. 1, the second sub-pixel 142 may include a second circuit element E2. In the vertical projection of the substrate 110, the second circuit element E2 is located between the second light-emitting elements L2 in the second pixel area P2. Since these second light-emitting elements L2 are located on the plurality of second corners A2 of the second pixel area P2, the central space of the second pixel area P2 can be used to set the first circuit element E1. Here, the space utilization rate of the second pixel area P2 is improved, and at the same time, the situation that lines or electrical elements are arranged outside the second pixel area P2 is reduced. In one embodiment, as shown in FIG. 1, the second circuit element E2 does not overlap with the second light-emitting elements L2. In another embodiment (not shown), the second circuit element E2 may partially overlap at least one of the second light-emitting elements L2. In one embodiment, the second circuit element E2 is electrically connected to the second light-emitting elements L2 to provide power or other signals. The second circuit element E2 may be, but is not limited to, one or more thin film transistors, capacitors, chips, traces, vias, and / or other wiring or electrical components.
於又一實施例中,如圖1所繪示,第一電路元件E1於第一畫素區域P1的位置與第二電路元件E2於第二畫素區域P2的位置以第一鏡射軸MA1呈鏡射關係。也就是說,相對於第一鏡射軸MA1,位於相鄰二畫素區域P(於此為第一畫素區域P1和第二畫素區域P2)的二電路元件(於此為第一電路元件E1和第二電路元件E2)的配置 互為鏡射。換句話說,即,第一電路元件E1及二電路元件E2中各元件位置的相對關係以第一鏡射軸MA1呈鏡射關係配置。 In yet another embodiment, as shown in FIG. 1, the position of the first circuit element E1 in the first pixel area P1 and the position of the second circuit element E2 in the second pixel area P2 take the first mirror axis MA1 Mirrored relationship. In other words, relative to the first mirror axis MA1, the two circuit elements (here, the first circuit are located in the adjacent two pixel areas P (here, the first pixel area P1 and the second pixel area P2) Configuration of element E1 and second circuit element E2) Mirror each other. In other words, that is, the relative relationship between the positions of the first circuit element E1 and the two circuit elements E2 is arranged in a mirror relationship with the first mirror axis MA1.
於另一實施例中,以下以其中三個相鄰的畫素區域P(第一畫素區域P1、第二畫素區域P2及第三畫素區域P3)作為示例來說明。於此,第一畫素區域P1及第二畫素區域P2的結構、角度及位置等關係大致上相同於前述實施例,故相同或相似之處不再贅述。 In another embodiment, three adjacent pixel areas P (first pixel area P1, second pixel area P2, and third pixel area P3) are taken as an example for description below. Here, the relationship among the structure, angle, and position of the first pixel area P1 and the second pixel area P2 are substantially the same as those in the foregoing embodiment, so the same or similarities will not be repeated.
於此實施例中,如圖1至圖2所繪示,第三子畫素143與第一子畫素141係相鄰設置。第三子畫素143位於基板110的第三畫素區域P3,而第三畫素區域P3的第四邊緣D4鄰近第一畫素區域P1的第三邊緣D3。 In this embodiment, as shown in FIGS. 1 to 2, the third sub-pixel 143 and the first sub-pixel 141 are adjacent to each other. The third sub-pixel 143 is located in the third pixel area P3 of the substrate 110, and the fourth edge D4 of the third pixel area P3 is adjacent to the third edge D3 of the first pixel area P1.
第三子畫素143包括複數第三發光元件L3。此些第三發光元件L3分別位於第三畫素區域P3的複數第三角落A3。此些第三發光元件L3中之二相鄰第三發光元件L3之間沿第三延伸軸EX3相距第三距離H3。在一實施態樣中,如圖1、圖2所繪示,第三子畫素143包括二第三發光元件L31、L32,且分別位於第三畫素區域P3的二個位於對角的第三角落A3,且此二第三發光元件L31、L32之間沿第三延伸軸EX3相距第三距離H3。 The third sub-pixel 143 includes a plurality of third light-emitting elements L3. The third light emitting elements L3 are respectively located in the third corners A3 of the third pixel area P3. Among the third light-emitting elements L3, two adjacent third light-emitting elements L3 are separated by a third distance H3 along the third extension axis EX3. In one embodiment, as shown in FIGS. 1 and 2, the third sub-pixel 143 includes two third light-emitting elements L31 and L32, and two of the third pixel regions P3 are located diagonally Three corners A3, and the two third light emitting elements L31, L32 are separated by a third distance H3 along the third extension axis EX3.
於一實施例中,如圖1至圖2,第一子畫素141與第三子畫素143中最接近的第一發光元件L11與第三發光元件L31之間相距第二間距S2,且第一距離H1大於第二間距S2。換言之,第一子畫素141中最接近第三子畫素143中其中一第三發光元件L31的第一發光元件L11,其與最接近第三子畫素143中第三發光元件L31之間的距離 (第二間距S2)小於同一第一子畫素141內的兩第一發光元件L11、L12之間的距離(第一距離H1)。同理,第三距離H3大於第二間距S2。如此,使得分別位於相鄰的畫素區域P的最相鄰的兩發光元件之間的距離相較於位於同一畫素區域P內的相鄰的兩發光元件之間的距離來得近,進而分別位於相鄰的畫素區域P的相鄰的發光元件的出光混色更佳地均勻,且使製程變異時的色偏影響或雲狀條紋更為減緩。 In an embodiment, as shown in FIGS. 1 to 2, the first light-emitting element L11 and the third light-emitting element L31 that are closest to the first sub-pixel 141 and the third sub-pixel 143 are separated by a second distance S2, and The first distance H1 is greater than the second distance S2. In other words, the first light-emitting element L11 in the first sub-pixel 141 closest to one of the third light-emitting elements L31 in the third sub-pixel 143 is closest to the third light-emitting element L31 in the third sub-pixel 143 distance (Second pitch S2) is smaller than the distance between the first light-emitting elements L11 and L12 in the same first sub-pixel 141 (first distance H1). Similarly, the third distance H3 is greater than the second distance S2. In this way, the distance between the two nearest neighboring light-emitting elements located in the adjacent pixel area P is shorter than the distance between the two neighboring light-emitting elements located in the same pixel area P, and then respectively The light emission and color mixing of the adjacent light-emitting elements located in the adjacent pixel area P are more uniform, and the influence of color shift or cloud stripes when the process is mutated is further reduced.
一實施例中,如圖1、圖2、圖6、圖7,第一距離H1於平行於沿第一間距S1的延伸方向的一分量C1大於第一間距S1,且第一距離H1於平行於沿第二間距S2的延伸方向的一分量C2大於第二間距S2。其中,分量C1即為第一距離H1垂直投影至沿第一間距S1的延伸方向的投影線上的投影分量,而分量C2即為第一距離H1垂直投影至沿第二間距S2的延伸方向的投影線上的投影分量。如此,使得分別位於相鄰的畫素區域P的最相鄰的發光元件之間的距離更佳地較於位於同一畫素區域P內的相鄰的發光元件之間的距離來得近,進而分別位於相鄰的畫素區域P的相鄰的發光元件的出光混色更佳地均勻。第三發光元件L3的配置方式視應用之發光二極體顯示器的設計而定。於其中一些實施例中,如圖1至圖2,此些第一發光元件L1於第一畫素區域P1的位置與此些第三發光元件L3於第三畫素區域P3的位置以第二鏡射軸MA2呈鏡射關係。其中,第二鏡射軸MA2位於第一畫素區域P1的第三邊緣D3與相鄰的第三畫素區域P3的第四邊緣D4之間。也就是說,相對於第二鏡射軸MA2,位於相鄰二畫素區域P(於此為第一畫素區域P1和第三畫素區域P3)的二子畫素140(於此 為第一子畫素141和第三子畫素143)的此些發光元件(於此為多個第一發光元件L1和多個第三發光元件L3)的配置互為鏡射。換言之,第一子畫素141的每一第一發光元件L1相對於第二鏡射軸MA2的每一垂直距離分別與所對應的第三子畫素143的每一第三發光元件L3相對於第二鏡射軸MA2的每一垂直距離大致相等。值得一提的是,距離大致相等之意係包括設計上相等或相似、或具有相同或相似概念、或具有相同或相似結構但可能於製程過程中產生的些微誤差。因此,距離大致相等之意可以包括預期中因製造條件或技術而產生公差的結果。於一實施態樣中,第二鏡射軸MA2與第三延伸軸EX3之間具有第三夾角θ3,第三夾角θ3介於18°~72°。於其中一實施態樣中,第一邊緣D1與第三邊緣D3的長度比例可以等於第二間距S2與第一間距S1的比例,使得位於不同畫素區域(於此為第一畫素區域P1、第二畫素區域P2和多個第三發光元件L3)的此些發光元件(於此為多個第一發光元件L1和多個第三發光元件L3)。 In one embodiment, as shown in FIG. 1, FIG. 2, FIG. 6, and FIG. 7, a component C1 of the first distance H1 parallel to the extending direction of the first distance S1 is greater than the first distance S1, and the first distance H1 is parallel A component C2 along the extending direction of the second interval S2 is larger than the second interval S2. The component C1 is the projection component of the first distance H1 perpendicularly projected onto the projection line along the extension direction of the first distance S1, and the component C2 is the projection of the first distance H1 vertically projected along the extension direction of the second distance S2 The projected component on the line. In this way, the distance between the nearest neighboring light-emitting elements in the adjacent pixel areas P is better than the distance between the adjacent light-emitting elements in the same pixel area P, and then respectively The light emission and color mixing of the adjacent light emitting elements located in the adjacent pixel area P are more uniform. The arrangement of the third light-emitting element L3 depends on the design of the light-emitting diode display used. In some embodiments, as shown in FIGS. 1 to 2, the positions of the first light-emitting elements L1 in the first pixel area P1 and the positions of the third light-emitting elements L3 in the third pixel area P3 are the second The mirror axis MA2 has a mirror relationship. The second mirror axis MA2 is located between the third edge D3 of the first pixel area P1 and the fourth edge D4 of the adjacent third pixel area P3. In other words, with respect to the second mirror axis MA2, the two sub-pixels 140 (here the first) are located in the adjacent two-pixel area P (here the first pixel area P1 and the third pixel area P3) The configuration of the light-emitting elements (here, the plurality of first light-emitting elements L1 and the plurality of third light-emitting elements L3 of the sub-pixel 141 and the third sub-pixel 143) mirror each other. In other words, each vertical distance of each first light-emitting element L1 of the first sub-pixel 141 relative to the second mirror axis MA2 is respectively opposite to each third light-emitting element L3 of the corresponding third sub-pixel 143 Each vertical distance of the second mirror axis MA2 is approximately equal. It is worth mentioning that the meaning that the distances are substantially equal includes the design is equal or similar, or have the same or similar concepts, or have the same or similar structure, but may cause slight errors in the manufacturing process. Therefore, the meaning that the distances are approximately equal may include the expected result of tolerance due to manufacturing conditions or technology. In one embodiment, the second mirror axis MA2 and the third extension axis EX3 have a third included angle θ 3 , and the third included angle θ 3 is between 18 ° and 72 °. In one embodiment, the length ratio of the first edge D1 and the third edge D3 may be equal to the ratio of the second pitch S2 and the first pitch S1, so that they are located in different pixel areas (here, the first pixel area P1 , The second pixel area P2 and the plurality of third light-emitting elements L3) of the light-emitting elements (here, the plurality of first light-emitting elements L1 and the plurality of third light-emitting elements L3).

FIG. 4 is a partial schematic diagram of FIG. 3. Please refer to FIG. 3 and FIG. 4. The light emitting diode display of this embodiment is similar to the light emitting diode display of the previous embodiment. The similar components are denoted by the same reference numerals. Only the differences between the two are described below. The same Or similar points will not be repeated. Specifically, the schematic diagram of the light-emitting diode display shown in FIG. 3 omits the illustration of the substrate 110, the first signal line 120, and the second signal line 130. The biggest difference between the LED display of FIG. 3 and FIG. 4 and the LED display of the previous embodiment is that each pixel area P has a hexagonal configuration, and each pixel area P has six other adjacent pixels Area P, below Taking three adjacent pixel regions P (first pixel region P1, second pixel region P2, and third pixel region P3) as an example. In this embodiment, the first sub-pixel 141, the second sub-pixel 142 and the third sub-pixel 143 are arranged adjacent to each other. The first sub-pixel 141 is located in the first pixel area P1 of the substrate 110, the second sub-pixel 142 is located in the second pixel area P2 of the substrate 110, and the third sub-pixel 143 is located in the third pixel area of the substrate 110 P3. The first sub-pixel 141 includes three first light-emitting elements L1, and is located at three non-adjacent first corners A1 of the first pixel area P1, respectively, and two adjacent first light-emitting elements L1 are separated by a first Distance H1. The second sub-pixel 142 includes three second light-emitting elements L2, and is respectively located in two non-adjacent second corners A2 of the second pixel area P2, and the two adjacent second light-emitting elements L2 are separated by a second Distance H2. The third sub-pixel 143 includes three third light-emitting elements L3, and is respectively located in three non-adjacent third corners A3 of the third pixel area P3, and the adjacent two third light-emitting elements L3 are separated by a third Distance H3.
於一實施例中,如圖3所繪示,可以多個子畫素140共用同一電路元件E,例如三個子畫素140(如以圖3為例是第一子畫素141、第三子畫素143及第四子畫素144)共用同一電路元件E。在對基板110的垂直投影上,電路元件E位於三個畫素區域P內之多個發光元件之間。由於各子畫素140的各發光元件可以位於其對應的畫素區域P的其中部分的角落上,因此電路元件E可設置於此些相鄰的子畫素140的未配置有發光元件的角落的空間。於此,相鄰的畫素區域P之間的剩餘空間利用率提高。於一實施態樣中,所述電路元件E分別與三個相鄰子畫素140中至少一發光元件電性連接以提供電源或其他訊號。所述電路元件E可以是但不限於一個或複數個薄膜電晶體、 電容、晶片、走線、導孔及/或其他線路或電性元件等。 In one embodiment, as shown in FIG. 3, multiple sub-pixels 140 may share the same circuit element E, for example, three sub-pixels 140 (such as the first sub-pixel 141 and the third sub-picture in FIG. 3 as an example) The pixel 143 and the fourth sub-pixel 144) share the same circuit element E. In the vertical projection on the substrate 110, the circuit element E is located between the plurality of light emitting elements in the three pixel regions P. Since each light-emitting element of each sub-pixel 140 may be located at a corner of a portion of its corresponding pixel area P, the circuit element E may be disposed at the corner of these adjacent sub-pixels 140 where no light-emitting element is disposed Space. Here, the remaining space utilization rate between adjacent pixel regions P is improved. In one embodiment, the circuit element E is electrically connected to at least one light-emitting element in three adjacent sub-pixels 140 to provide power or other signals.

於一實施例中,如圖4所示,第一子畫素141與第二子畫素142中最接近的第一發光元件L11與第二發光元件L21之間相距第一間距S1,且第一距離H1大於第一間距S1。第一子畫素141與第三子畫1素143中最接近的第一發光元件L11與第三發光元件L31之間相距第二間距S2,且第一距離H1大於第二間距S2。第二子畫素142與第三子畫素143中最接近的第二發光元件L21與第三發光元件L31之間相距第三間距S3,第二距離H2大於第三間距S3且第二距離H2大於第一間距S1。同理,第三距離H3大於第三間距S3且第三距離H3大於第二間距S2。如此,使得分別位於相鄰的畫素區域P的最相近的三個發光元件之間的距離相較於位於同一畫素區域P內的相鄰的兩發光元件之間的距離來得近,進而分別位於相鄰的畫素區域P的相鄰的發光元件的出光混色更佳地均勻,且使製程變異時的色偏影響或雲狀條紋更為減緩。 In one embodiment, as shown in FIG. 4, the first light-emitting element L11 and the second light-emitting element L21 that are closest to the first sub-pixel 141 and the second sub-pixel 142 are separated by a first distance S1, and the first A distance H1 is greater than the first distance S1. The first sub-pixel 141 and the third sub-pixel 1 143 are closest to the first light-emitting element L11 and the third light-emitting element L31 by a second distance S2, and the first distance H1 is greater than the second distance S2. The second sub-pixel 142 and the third sub-pixel 143 that are closest to the second light-emitting element L21 and the third light-emitting element L31 are separated by a third distance S3, the second distance H2 is greater than the third distance S3 and the second distance H2 Greater than the first pitch S1. Similarly, the third distance H3 is greater than the third interval S3 and the third distance H3 is greater than the second interval S2.

綜上所述,本發明實施例之所提供的發光二極體顯示器,其畫素區域為多邊形,利用將發光元件配置於同一畫素區域的角落,而各發光元件係與相鄰的畫素區域內的至少其中一發光元件最接近,因此,分別位於相鄰的畫素區域的最相鄰的發光元件之間的距離相較於位於同一畫素區域內的相鄰的發光元件之間的距離來得近。如此,分別位於相鄰的畫素區域的相鄰的發光元件的出光混色可以更佳地均勻,且因製程變異下的色偏影響或雲狀條紋可以更為減少。與一般有機發光二極體顯示器不同的地方在於將發光元件 配置於同一畫素區域的不同角落且與發光元件相鄰的畫素區域內的至少其中一發光元件更為接近時,可再將電路元件置於同一畫素區域的兩發光元件之間或相鄰兩畫素區域的發光元件之間時,可以促使畫素區域的空間利用率更加提高。 In summary, the light-emitting diode display provided by the embodiment of the present invention has a pixel area that is polygonal. The light-emitting elements are arranged at the corners of the same pixel area, and each light-emitting element is adjacent to the adjacent pixel At least one of the light-emitting elements in the area is the closest. Therefore, the distance between the nearest neighboring light-emitting elements in the adjacent pixel areas is compared to that between the adjacent light-emitting elements in the same pixel area The distance is close. In this way, the light emission and color mixing of the adjacent light-emitting elements located in the adjacent pixel regions can be more uniform, and the influence of color shift or cloud stripes due to process variation can be further reduced. The difference from the general organic light emitting diode display is that the light emitting element When at least one of the light-emitting elements in the pixel area adjacent to the light-emitting element is arranged in different corners of the same pixel area, the circuit element can be placed between two light-emitting elements in the same pixel area or in phase When the light-emitting elements are adjacent to two pixel regions, the space utilization rate of the pixel regions can be further improved.
