Abstract

The invention provides a flexible display panel. The flexible display panel comprises a substrate, a cathode layer, a pixel definition layer, a light emitting layer and an anode layer, wherein the cathode layer is arranged on the substrate and provided with a first through hole, the pixel definition layer is arranged on the cathode layer and used for defining a pixel region, the pixel definition layer is provided with a second through hole, the light emitting layer is arranged in the pixel region defined by the pixel definition layer, the anode is arranged on the light emitting layer, the anode layer passes through the first through hole and the second through hole and is connected to a target position, and the anode layer is insulated from the cathode layer. The anode layer is arranged onthe light emitting layer, and the cathode layer is arranged below the light emitting layer, thereby being capable of thickening the cathode layer, thus reducing the impedance of the cathode layer, and solving a technical problem that the cathode layer of the existing flexible display panel is high in impedance.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a flexible display panel. Background technique [0002] Existing flexible display panels adopt top emission to improve the resolution of the panel, so top emission flexible display panels are widely used, such as figure 1 As shown, the light emitted in the existing top-emitting flexible display panel needs to be transmitted through the cathode layer, so the thickness of the cathode will be reduced to achieve better light transmittance, but the reduction of the thickness of the cathode will lead to an increase in the resistance of the cathode , resulting in a significant pressure drop. [0003] Therefore, the existing flexible display panel has a technical problem of relatively high impedance of the cathode layer. Contents of the invention [0004] The invention provides a flexible display panel, which is used to solve the technical problem of relatively large cathode...
