[0187] 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.

[0188] 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.

[0189] 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.
