By using a graphene film in both conductive and non-conductive states as a protective layer in OLED devices to cover the sidewalls and bottom of the opening area, and combining this with a second pixel delimiting layer to block adjacent light-emitting devices, the cavity length variation and short-circuit problems caused by thin sidewall materials are solved, thereby improving luminous brightness and reliability.

AI Technical Summary
In the process of improving the brightness of existing OLED devices, the thin sidewall material leads to changes in cavity length, which affects light emission. Furthermore, the thin sidewall material is prone to short circuit problems, and the low resolution of the resin material limits the anode light emission area.
Semiconductor films, especially graphene films, in both conductive and non-conductive states are used to cover the sidewalls and bottom of the opening area as a protective layer, which improves the problem of thin sidewall materials and blocks adjacent light-emitting devices through a second pixel delimiting layer.
It improves the brightness and reliability of OLED light-emitting devices, reduces the restriction of the protective layer on the light-emitting area, avoids short circuits, and enhances the area utilization of the light-emitting area.
