Problems solved by technology

[0003] In order to increase the screen-to-body ratio, the current common practice is to reduce the size of the bezel area, but the signal traces in the bezel area will be too dense, and capacitive coupling between signal traces will easily occur, resulting in various mura on the display device.

Abstract

The invention discloses a display panel and a display device, which comprises a device-setting zone, a first non-display zone and a display zone. The first non-display zone is set around the device-setting zone, and the display zone is set around the first non-display zone. The display zone comprises a plurality of data lines, a public electrode layer and a plurality of thin-film transistors arranged on a substrate, wherein a plurality of data lines comprise a plurality of first data lines and a plurality of second data lines. The first data lines comprise a conventional part and a connectionpart, and the conventional part is in the display zone. The connection part is in the first non-display zone, which bypasses the device-setting zone and then is set up. The thin-film transistors include a gate, a semiconductor part, a source electrode and a drain electrode, wherein the source electrode, the drain electrode, the second data lines and the conventional part are in the same layer andmade from the same material. The first non-display zone comprises at least one shielding layer, and at least a shielding layer and the connection part are in different layers. Compared with the priorart, the display panel and the display device are beneficial to improve the mura caused by the coupling of the display panel, and can increase the screen proportion of the display device.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] Display devices such as mobile phones and tablet computers need to reserve installation areas for devices such as cameras and photoelectric sensors. These installation areas are usually set at the top of the display area of ​​the display device, and the signal lines that originally passed through the installation area need to bypass the installation area. , so that the frame area between the installation area and the display area for signal routing can only be used as a non-display area, reducing the screen ratio of the display device. [0003] In order to increase the screen-to-body ratio, the current common practice is to reduce the size of the bezel area, but the signal traces in the bezel area will be too dense, and capacitive coupling between signal traces will easily occur, resulting in va...
