Problems solved by technology

However, since the touch traces are on different metal layers, this layout method may cause uneven distribution of touch trace resistance, because the film thickness and resistivity between the gate line metal layer and the data line metal layer are different. , the resistance of two adjacent touch traces is different, and the impedance of the metal layer of the gate line is relatively large, and the impedance of the metal layer of the gate line and the metal layer of the data line is greatly different, resulting in the difference between the touch traces of different metal layers. The impedance between them is not easy to match, thus affecting the display quality

Abstract

The invention discloses a display panel and a display device, which belong to the field of display technology. The display panel includes a base substrate, a display area, a non-display area, and a fan-out area; the display area includes a plurality of pixel units, a plurality of gate line groups, a plurality of One data line and multiple touch lines, the gate line group includes two adjacent gate lines, the two gate lines are located between two adjacent rows of pixel units; the gate lines are located on the gate metal layer, the data lines and The traces are located on the source / drain metal layer; the fan-out area includes multiple first fan-out traces and multiple second fan-out traces, and the first fan-out traces are located on the gate metal layer and / or the source / drain metal layer , and each second fan-out line is located on the source / drain metal layer. The display device includes the above-mentioned display panel. The present invention can save cost, and can also make the impedances of all traces used for touch control consistent, so that the display quality of the display panel can be further improved.

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] In the prior art, display devices can be classified into cathode ray tube display CRT, plasma display PDP, liquid crystal display LCD, light emitting diode display LED, active light emitting diode display OLED, etc. according to different manufacturing materials. At present, flat panel displays such as liquid crystal display LCD and light emitting diode display LED have gradually replaced traditional displays such as cathode ray tube display CRT, etc., are widely used in various industries, and become an indispensable component of most electronic equipment. [0003] The current mainstream display device generally adopts the scan driving method, that is, the gate driving circuit sequentially applies signals to the gate lines connected to the sub-pixels in each row to turn on the sub-pixels in eac...
