Title: IN-CELL TOUCH SCREEN AND DISPLAY DEVICE
Abstract:
An in-cell touchscreen and a display device, comprising alternately arranged first touch electrodes (02) and second touch electrodes (03). The second touch electrodes (03) consist of first subelectrodes (31) and second subelectrodes (32) alternating in a first direction, arranged in an orthogonal connection, and serially connected head-to-tail, the first subelectrodes (31) extend in the first direction, the second subelectrodes (32) extend in the direction perpendicular to the first direction, and the orthographic projections of the second electrodes (32) on the array substrate (1) fall within the orthographic projections of the first touch electrodes (02) on the array substrate (1). Therefore, equivalent to arranging the second touch electrodes (03) into the shape of folded lines, this increases the area of opposite arrangements between the first touch electrodes (02) and the second touch electrodes (03), thus increasing the mutual capacitance between the first touch electrodes (02) and the second touch electrodes (03) in a unit area, and increasing the inductive sensitivity of the in-cell touchscreen when being touched.
