Abstract
The present disclosure provides a backplate and a flexible display panel thereof. Wherein the backplate includes a polyethylene terephthalate (PET) layer, and a graphene layer disposed on the PET layer. The present disclosure provides a backplate, which adopts a novel hierarchical structure design of graphene material, so that it realizes function of a current backplate while adding new heat dissipation functions. Compared with the current flexible display panel, the flexible display panel reduced a corresponding heat dissipation function layer, therefore having an effectively reduced thickness, and improved folding performance.
Claims5
A backplate, comprising:
- a polyethylene terephthalate (PET) layer;
- a graphene layer disposed on the PET layer;
- a pressure sensitive adhesive layer disposed on the graphene layer;
- a first release film layer disposed on the pressure sensitive adhesive layer and is an easy release film layer;
- and
- a second release film layer disposed under the PET layer and is a heavy release film layer, wherein a release force on the heavy release film layer is greater than a release force of the easy release film layer.
