Display panel and manufacture method thereof

Abstract

The invention discloses a display panel and a manufacture method thereof. The display panel comprises a display area and a border area. The display panel comprises a cover plate and a display substrate, wherein the cover plate and the display substrate are oppositely arranged. The cover plate comprises a first conductive layer. The display substrate comprises a TFT substrate and a pixel definition layer which is arranged on one side, which faces the cover plate, of the TFT substrate. The pixel definition layer comprises an opening area and an opening-free area. The opening area is provided with a light-emitting function layer. A first electrode is arranged between the light-emitting function layer and the TFT substrate. The opening-free area is provided with a raised structure facing the cover plate. A second electrode layer is arranged on the light-emitting function layer and the surface of the raised structure. The second electrode layer is electrically connected with the first conductive layer at a position corresponding to the raised structure. Wiring is arranged in a preset area, which is corresponding to the border area, of the display substrate. The wiring is used for providing the work voltage of the second electrode layer. The first conductive layer is electrically connected with the wiring. According to the display panel, the width of the border area is reduced, and the problem of voltage drop of the second electrode layer is avoided.

Description

technical field [0001] The present invention relates to the technical field of display devices, and more particularly, to a display panel and a manufacturing method thereof. Background technique [0002] With the continuous development of science and technology, more and more electronic devices with display function are widely used in people's daily life and work, which brings great convenience to people's daily life and work, and has become an indispensable part of the current people. important tool that is missing. The main component of the electronic device to realize the display function is the display panel, and the OLED display panel is one of the current mainstream display panels. [0003] refer to figure 1 , figure 1 It is a schematic structural diagram of a common OLED panel in the prior art. The OLED display panel includes: a cover plate 12 and an array substrate 11 which are arranged oppositely. The OLED display panel has a display area A and a frame area B. ...

AI Technical Summary

Problems solved by technology

[0004] Depend on figure 1 It can be seen that in the existing OELD display panel, the second via hole Via2 needs to be provided on the pixel definition layer 116 in the frame area B, so as to connect the cathode 114 to the wiring 115, the manufacturing process is complicated, and the setting of the second via hole Via2 It is not convenient for the design of narrow frame of OLED display panel

Moreover, as the size of the display panel continues to increase, the number of pixel units in the display panel is increasing. In the prior art, the entire cathode layer is only connected to the wiring that provides the cathode voltage in the frame area, resulting in a drop in the voltage of the cathode ( IRdrop) is significantly increased, affecting the display effect
