Problems solved by technology

Usually, the display panel is provided with a plurality of sub-pixel units, and when the display area of ​​the display panel has a special shape, the number of sub-pixel units contained in the special-shaped area will be different from the number of sub-pixel units contained in the non-special-shaped area, thus As a result, the load value of the special-shaped area is different from that of the non-special-shaped area, which in turn leads to uneven brightness of the display panel

Abstract

The invention discloses a display panel and a display device, and relates to the technical field of display. The display panel comprises a display area, a non-display area and a plurality of gate lines. The display area comprises a first edge, the first edge comprises a first concave section, and the first concave section is concave towards the inner part of the display area; the display area comprises a first display area and a second display area; the gate lines include a first gate line located in the first display area and a second gate line located in the second display area; the number of pixels electrically connected with the first gate line is less than the number of pixels electrically connected with the second gate line; the non-display area comprises a plurality of first vertical shift registers and second vertical shift registers, the driving signal output end of each first vertical shift register is electrically connected with the first gate line, the driving signal outputend of each second vertical shift register is electrically connected with the second gate line, the output current of each first vertical shift register is not equal to the output current of each second vertical shift register. This is advantageous for balancing the loads of the first display area and the second display area.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel and a display device. Background technique [0002] Common display devices, such as monitors, televisions, mobile phones, tablet computers, etc., usually have a display area that is a regular rectangle, and a plurality of sub-pixels distributed in an array are arranged in the display area. [0003] In recent years, with the development of science and technology, the use of display devices with display panels has become more and more extensive, making people's requirements for display panels more and more diverse, and they are no longer satisfied with large-size, high-definition display panels. Conventional performance indicators such as high temperature also have more diverse requirements for the shape of the display panel, so there are special-shaped display panels. [0004] The emergence of special-shaped display panels breaks through the limi...
