Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0030] In the display panel, by setting a break on the gate signal line, the gate signal line no longer runs through the display area in a horizontal direction, so that the display area at the lower left of the dotted line (within half the area of ​​the display area of ​​the entire display panel) is invalid. The abnormality in the line area will not affect the gate signal, reducing the defective rate of products, and by repairing the connection between the line and the f...

Abstract

The invention relates to a display panel and a display device. The display panel comprises a display area, a non-display area and a grid signal source; the display area comprises a grid signal layer, the grid signal layer comprises a grid signal line connected with the grid signal source, and a fracture is formed in the grid signal line; the grid signal line is divided into a first signal line segment and a second signal line segment, and the first signal line segment is connected with the grid signal source and electrically connected with the corresponding scanning line through the first via hole. According to the display panel, the fractures are formed in the grid signal lines, so the grid signal lines do not transversely penetrate through the display area any more, transmission of grid signals is not affected by abnormity of an invalid grid line area in the range of the display area corresponding to the lower left portion of a dotted line formed by connecting the fractures, and the reject ratio of products is reduced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device including the display panel. Background technique [0002] OLED (Organic Light-Emitting Diode) display technology has the characteristics of self-illumination. It uses very thin organic material coating and glass substrate. When current passes through, these organic materials will emit light, and the OLED display screen has a large viewing angle. And it can significantly save power. It has been widely used on mobile phone screens. In terms of medium and large sizes, it is also striving to move towards the mass production stage, and the realization of flexible and foldable functions is the key direction of future development. [0003] The current design schematic diagram of a medium-sized flexible OLED product is as follows: figure 1 As shown, in order to realize the rollable function, the directional wiring of the gate line 211 is su...
