Problems solved by technology

However, after the binding electrode is transferred, it will flow into the display panel. If the gap between the upper and lower substrates of the display panel is too large, the binding layer will flow too much into the display panel, which will cause the impedance of the binding electrode to be too large. or risk of disconnection
[0003] Therefore, the problems of excessive impedance or risk of disconnection in the binding electrodes of the existing display panels need to be solved

Abstract

The present disclosure provides a display panel and a display device. A binding area of the display panel comprises a first metal layer, a first insulating layer, a second metal layer, a second insulating layer, a heightening layer, a transparent electrode layer and a binding electrode which are arranged in a stacked manner. The heightening layer is used to reduce a gap between a first substrate and a second substrate corresponding to the binding area. Increase of impedance or risk of wire breakage caused by the fact that the binding electrode flows too much into the display panel can be avoided. The binding electrode is connected with the first metal layer and the second metal layer through the transparent electrode layer, so that the signal attenuation risk is reduced.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] With the development of large-sized display panels, splicing screen technology has been widely used in panel production. In the manufacturing process of traditional display panels, the frame area of ​​the array substrate needs to reserve an Outer Lead Bonding (OLB) area for bonding Chip On Film (COF), resulting in the frame area of ​​the display panel It is usually wide, which causes the picture of the splicing screen to be divided, which destroys the continuity and integrity of the image, seriously affects the overall effect of the splicing display screen, and cannot achieve high-quality seamless splicing display. To solve this problem, COF side bonding (side bonding) technology can narrow the frame of the panel, thereby narrowing the seam. In the COF side bonding technology, the COF is bonded t...
