[0113] Reference Figure 1-2 The diagram shows a related display panel structure. The display panel 100 includes a substrate 1 and an isolation structure 2 disposed on one side of the substrate 1. The isolation structure 2 forms an isolation opening 21 for accommodating light-emitting devices 3. Adjacent light-emitting devices 3 are separated by the isolation structure 2.

[0114] In this process, by setting an isolation structure 2 at the gap between the light-emitting devices 3, the functional film layers of adjacent light-emitting devices 3 are separated. Thus, in the evaporation process of multiple functional film layers, it is only necessary to perform evaporation on the entire display panel 100, without using a mask to perform evaporation on the area where the light-emitting devices 3 are located to form functional film layers. Therefore, the process of using the isolation structure 2 for evaporation does not need to consider the alignment accuracy problem during evaporation, thereby allowing the gap between the light-emitting devices 3 to be designed to be smaller, so as to increase the pixel density.

[0115] However, with the increase of PPI (pixel density unit), the pixel aperture of the display panel 100 with the above structure will decrease, and the inability to increase the pixel aperture ratio will result in low brightness of the display panel.

[0116] Based on this, this application provides a display panel solution, as detailed in the following embodiments.

[0117] Reference Figure 3 and 4 As shown, one embodiment of this application provides a display panel 100, which includes a substrate 1, a driving circuit layer 4, a pixel defining layer 6, and a plurality of light-emitting devices 3.

[0118] The driving circuit layer 4 is disposed on one side of the substrate 1. The driving circuit layer 4 is provided with a plurality of pixel driving units and a plurality of vias 51.

[0121] The first via 511 has a first shortest distance a between its orthographic projection on the substrate 1 and the orthographic projection of its corresponding first pixel opening 611 on the substrate 1, and the second via 512 has a second shortest distance b between its orthographic projection on the substrate 1 and the orthographic projection of its corresponding second pixel opening 612 on the substrate 1. The first shortest distance a and the second shortest distance b are not equal.

[0122] The display panel 100 provided in this application has a first shortest distance a between the orthographic projection of the first via 511 on the substrate 1 and the orthographic projection of the corresponding first pixel opening 611 on the substrate 1, and a second shortest distance b between the orthographic projection of the second via 512 on the substrate 1 and the orthographic projection of the corresponding second pixel opening 612 on the substrate 1. The first shortest distance a and the second shortest distance b are not equal, which is beneficial to compressing the space outside the pixel opening, thereby increasing the pixel aperture ratio, increasing the brightness of the display panel, and improving the display performance of the display panel.

[0123] Please continue to refer to Figure 4 As shown, in one embodiment, the first shortest distance a is not greater than the second shortest distance b, which is beneficial for compressing the space outside the first pixel opening 611, thereby improving the pixel aperture ratio.

The recessed portion 62 includes a second straight portion C2 close to the first straight portion C1 in a second direction (X direction in the figure). The orthographic projection of the first via 511 on the substrate 1 is located on the side where the orthographic projection of the corresponding second straight portion C2 on the substrate 1 is away from the orthographic projection of the corresponding first straight portion C1 on the substrate 1. The first direction and the second direction intersect, wherein the shortest distance between the orthographic projection of the first via 511 on the substrate 1 and the orthographic projection of the corresponding second straight portion C2 on the substrate 1 is a first shortest distance a. The recessed portion 63 is used to avoid the corresponding first via 511, which is beneficial for compressing the space outside the first pixel opening 611 and improving the pixel aperture ratio.

[0125] The second direction can be at an angle of 70 degrees, 80 degrees, 85 degrees, etc., to the first direction. Preferably, the second direction is at an angle of 90 degrees to the first direction, that is, the second direction is perpendicular to the first direction.

[0127] Preferably, the length of the second straight section C2 is less than the length of the first straight section C1.

[0128] Preferably, the first straight section C1 is parallel to the second straight section C2.

[0129] In one embodiment, the emission color of the first light-emitting device is different from the emission color of the second light-emitting device to enhance the richness of the display.

Each pixel includes a first light-emitting device, a second light-emitting device, and a third light-emitting device. In the same pixel, the orthographic projections of the second via 512 corresponding to the second light-emitting device and the third via 513 corresponding to the third light-emitting device on the substrate 1 are located between the orthographic projections of the second pixel opening 612 corresponding to the second light-emitting device and the third pixel opening 613 corresponding to the third light-emitting device on the substrate 1, which is beneficial to improving the pixel aperture ratio.

[0178] Please refer to Figure 7 As shown, in one embodiment, the display panel 100 further includes an isolation structure 2. The isolation structure 2 is disposed on the side of the driving circuit layer 4 away from the substrate 1. The isolation structure 2 encloses and forms a plurality of isolation openings 21, which are connected to the corresponding pixel openings 61. By setting the isolation structure 2 between the light-emitting devices 3, the functional film layers of adjacent light-emitting devices 3 are separated. Thus, in the evaporation process of multiple functional film layers, it is only necessary to perform evaporation on the entire surface of the display panel 100, without using a mask to evaporate the area where the light-emitting devices 3 are located to form functional film layers. Therefore, the evaporation process using the isolation structure 2 does not need to consider the alignment accuracy problem during evaporation, thereby allowing the gap between the light-emitting devices 3 to be designed to be smaller, thereby increasing the pixel density.

The orthographic projection of the end of the first support portion 23 near the second support portion 24 on the substrate 1 is located within the orthographic projection of the second support portion 24 on the substrate 1, so that the first support portion 23 of the isolation structure 2 connects the upper electrode 33, thereby making the first support portion 23 and the upper electrode 33 form a common electrode for driving.

[0181] Please refer to Figure 8 and 9 As shown, in one embodiment, the first support portion 23 includes a first sub-support portion 231 and a second sub-support portion 232.
