Plain area P. The shape of the pixel area P in the illustration depends on the design of the light-emitting diode display depending on different application considerations or display characteristic specifications. Here, the shape of the pixel area P is only an example, and is not for the embodiment of the present invention. limited. In addition, in order to clearly show the arrangement of the light-emitting elements in the sub-pixels 140, part of the illustration omits the drawing of the substrate 110, the first signal line 120, the second signal line 130, the circuit element E1 and the circuit element E2.

In an embodiment, the following takes two adjacent pixel regions P (first pixel region P1 and second pixel region P2) as an example.

The first sub-pixel 141 and the second sub-pixel 142 are arranged adjacent to each other. The first sub-pixel 141 is located in the first pixel area P1 of the substrate 110, and the second sub-pixel 142 is located in the second pixel area P2 of the substrate 110. As shown in FIG. 2, the first edge D1 of the first pixel area P1 is adjacent to the second edge D2 of the second pixel area P2. As shown in FIG. 2, the first edge D1 and the second edge D2 are separated by one interval. It should be noted that since the pixel area P refers to the area defined by the intersection of any two adjacent first signal lines 120 and any two adjacent second signal lines 130, the edges of the pixel area P (for example, The first edge D1, the second edge D2, the third edge D3, the fourth edge D4, etc.) refer to the edges of the plural first signal lines and plural second signal lines, or are repeated by plural similar elements or other lines The edge under the repeating periodic unit caused by the arrangement. For ease of explanation, the first edge D1, the second edge D2, and the third edge D3 shown in FIG. 2 are indicated by solid lines.

The first sub-pixel 141 includes a plurality of first light-emitting elements L1, and the first light-emitting elements L1 are respectively located in a plurality of first corners A1 of the first pixel area P1. Among the first light emitting elements L1, two adjacent first light emitting elements L1 are separated by a first distance H1 along the first extension axis EX1. In one embodiment, as shown in FIGS. 1 and 2, the first sub-pixel 141 includes two first light-emitting elements L1, here are a first light-emitting element L11 and a first light-emitting element L12, and are located in the first A first corner A1 of two opposite corners of a pixel area P1, and the first light-emitting elements L11 and L12 are separated by a first distance H1 along a first extension axis EX1.

The second sub-pixel 142 includes a plurality of second light-emitting elements L2, and the second light-emitting elements L2 are respectively located in a plurality of second corners A2 of the second pixel area P2. Among the second light-emitting elements L2, two adjacent second light-emitting elements L2 are separated by a second distance H2 along the second extension axis EX2. In one embodiment, as shown in FIGS. 1 and 2, the second sub-pixel 142 includes two second light-emitting elements L2, here are second light-emitting elements L21 and second light-emitting elements L22, and are respectively located at two second corners A2 of two opposite corners of the second pixel area P2, and the two second light-emitting elements The elements L21 and L22 are separated by a second distance H2 along the second extension axis EX2. It should be noted that the number of the first light-emitting element L1 and the second light-emitting element L2 shown depends on the electrical design of the applied light-emitting diode display, so the number of the first light-emitting element L1 and the second light-emitting element L2 It is only an example, not a limitation of the embodiments of the present invention.

The positions of the first light emitting elements L1 in the first pixel area P1 and the positions of the second light emitting elements L2 in the second pixel area P2 are in a mirror relationship with the first mirror axis MA1. The first mirror axis MA1 is located between the first edge D1 of the first pixel area P1 and the second edge D2 of the adjacent second pixel area P2, that is, the first mirror axis MA1 is located at the above-mentioned interval Inside. That is, with respect to the first mirror axis MA1, the two sub-pixels 140 (here, the first sub-pixels of the adjacent two-pixel area P (here, the first pixel area P1 and the second pixel area P2)) The configuration of the light-emitting elements (here, the plurality of first light-emitting elements L1 and the plurality of second light-emitting elements L2 of the pixel 141 and the second sub-pixel 142) are mirrors of each other. In other words, each vertical distance of each first light-emitting element L1 of the first sub-pixel 141 relative to the first mirror axis MA1 is respectively opposite to each second light-emitting element L2 of the corresponding second sub-pixel 142 Each vertical distance of the first mirror axis MA1 is equal. In one embodiment, the first mirror axis MA1 and the first extension axis EX1 have a first included angle θ ₁ , and the first included angle θ _{1 is} between 18 ° and 72 °. 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 .

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.

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.

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.

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.

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 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.

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.

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.

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.

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.

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.

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.

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 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).

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.
