The invention relates to the technical field of display, and particularly discloses an array substrate and a display device. The array substrate comprises grid lines and a display area, wherein the grid lines are divided into first grid lines and second grid lines, the display area comprises a plurality of common electrodes distributed on the substrate in an array mode, the common electrodes are reused as touch electrodes, the two touch electrodes are provided with first conductive parts and second conductive parts which are distributed in a staggered mode in a second direction interval area, the first conductive part is connected with one touch electrode, the second conductive part is connected with the other touch electrode, the orthographic projection of the first conductive part and the orthographic projection of the second conductive part are overlapped with the orthographic projection of the first grid line, and the orthographic projection of the second grid line is overlapped with the orthographic projection of the touch electrode. According to the invention, the first grid lines are overlapped with the first conductive parts and the second conductive parts, so that when the first grid lines are charged, the closing or opening pulling influence of the first grid lines on the edges of the touch electrodes is opposite, the charging rate influence directions are also opposite, mutual counteracting is achieved visually, and the cross grain problem is solved.
Description
technical field [0001] The present application generally relates to the field of display technology, and in particular, discloses an array substrate and a display device. Background technique [0002] In the existing TDDI (Touch and Display Driver Integration) product touch electrode design, the pixel electrode film layer on the surface of the substrate is used not only as the common electrode during display, but also as the touch electrode during scanning, while the touch electrode in the conventional display area usually uses Rectangular blocks are designed to detect and receive touch signals at different positions, and different rows of touch electrodes overlap with different rows of gate touch scanning lines. In the existing CLK GOA drive design, due to the influence of the physical division between adjacent touch electrodes, there is a difference in charging rate between the edge row of the touch electrodes and the middle row of the touch electrodes, resulting in the pr...
