Problems solved by technology

However, in the case of a narrow bezel design (such as figure 2 As shown), when the frame glue partially covers the GOA Busline, the width from the edge of the GOA Busline to the frame glue is significantly reduced, and the protective effect of the frame glue on the GOA Busline is obviously weakened. When the display panel is subjected to high temperature and high humidity tests, it is easy to The intrusion of water vapor caused the corrosion of the via hole on the far side of the GOA Busline, and the line failed

Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0027] see image 3 A preferred embodiment of the present invention provides a display panel, which is a narrow frame display panel, such as a liquid crystal display panel (LCD, Liquid Crystal Display) or an organic light-emitting diode panel (OLED, Organic Light-Emitting Diode). The display panel includes a display area and a non-display area. In the non-display area, the display panel includes two parts, a GOA circuit and a GOA Busline. The GOA circuit is used to...

Abstract

The invention provides a display panel, which comprises a display area and a non-display area surrounding the display area. In the non-display area, the display panel comprises a substrate base plate,a line layer and frame glue; the line layer is arranged on the surface of the substrate base plate; the line layer comprises a first surface facing away from the substrate base plate and a side surface connected between the first surface and the substrate base plate; the frame glue comprises a first portion which at least partially covers the first surface and a second portion which covers the side surface; the first portion and the second portion are mutually connected, and both the first portion and the second portion comprise a protective material; and the protective material is used for preventing water and oxygen from invading the line layer. The display panel in the invention, by covering a protective material on the line layer, effectively prevents the phenomenon that the moistureand oxygen infiltrate into the display panel due to a narrow bezel design of the display panel, resulting in the line layer being corroded and breaking down. The invention further provides a display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] With the improvement of the performance of TFT (Thin Film Transistor, thin film transistor), GOA (Gata On Array, gate drive unit disposed on the array substrate) technology has been widely used in current display panels. GOA technology has a series of advantages such as saving Gate IC (Gate Integrated Circuit, gate drive), improving product yield, and realizing the narrow frame design of the display panel. The general GOA wiring structure is as follows: figure 1 shown. GOA includes two parts: GOA circuit and GOA Busline (route). The frame glue is located outside the GOA Busline and has a certain distance from the GOA circuit. [0003] However, when industry researchers are pursuing display panels with narrow borders and coating the border adhesive on the GOA Busline to effectively reduce the border wid...
