IN-CELL TOUCH PANEL AND DISPLAY DEVICE

摘要

The present disclosure provides an in-cell touch panel and a display device. An entire common electrode layer on an array substrate is divided so as to form a plurality of touch driving sub-electrodes and a plurality of common sub-electrodes spaced apart from each other and arranged alternately. The touch driving sub-electrodes are electrically connected to each other via a touch driving signal line so as to form a touch driving electrode, and the common sub-electrodes are electrically connected to each other via a common electrode signal line to form a common electrode. Touch sensing electrodes are arranged on an opposite substrate and cross the touch driving electrodes.

主权项

1. An in-cell touch panel, comprising an array substrate having a common electrode layer, and an opposite substrate arranged opposite to the array substrate, wherein
the common electrode layer of the array substrate comprises a plurality of touch driving sub-electrodes and a plurality of common sub-electrodes arranged in a matrix form and spaced apart from each other, and the touch driving sub-electrodes and the common sub-electrodes are arranged alternately in both a row direction and a column direction of the matrix; a plurality of touch driving signal lines and a plurality of common electrode signal lines are arranged on the array substrate, in the row or column direction of the matrix, the touch driving sub-electrodes at both sides of the common sub-electrode are electrically connected to each other via the touch driving signal line, so as to form a touch driving electrode, and in the row or column direction of the matrix, the common sub-electrodes at both sides of the touch driving sub-electrode are electrically connected to each other via the common electrode signal line, so as to form a common electrode; and a plurality of touch sensing electrodes are arranged on the opposite substrate and cross the touch driving electrodes, and an orthographic projection of the touch sensing electrode onto the array substrate is located at a region where the common sub-electrode is located.
