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, and belongs to the technical field of display. The display panel comprises a substrate, a display area, a non-display area and a fan-out area. The display area comprises a plurality of pixel units, a plurality of grid line sets, a plurality of data lines and a plurality of touch lines. Each grid line set includes two adjacent grid lineslocated between adjacent two rows of pixel units. The grid lines are located on a grid metal layer, the data lines and the touch lines are all located in a source / drain metal layer. The fan-out areaincludes a plurality of first fan-out lines and a plurality of second fan-out lines, the first fan-out lines are located on the grid 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 display panel. The display panel and the display device can save cost and make the impedance of all the touch lines consistent, thereby improving the display quality of the display panel.

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...
