AI Technical Summary
The short lifespan of existing display panels is mainly due to the accumulation of Joule heat at the interface of the light-emitting functional layer during the light-emitting process, which leads to severe heat generation and affects luminous efficiency and lifespan.
A dual-layer pixel-defining layer structure is adopted, with a heat-conducting layer distributed on the sidewalls of the first and second sub-pixel-defining layers, connected to the same side facing the pixel opening. This layer is used to dissipate Joule heat and transfer heat from the light-emitting area to the non-light-emitting area through the heat-conducting layer.
It effectively improves the resolution of the display panel and the lifespan of the device, and can better dissipate Joule heat, thereby improving device performance.
