Abstract

A conductive layer of a touch sensor and a pixel electrode conductive layer of a display panel are integrated to a touch display panel during the same fabrication. The touch sensor defines a plurality of sensor groups that are insulated from each other in a same conductive layer, and each of the sense groups is divided into a plurality of mutually-coupled first electrodes, a plurality of mutually-coupled second electrodes and a plurality of mutually-coupled third electrodes. The first electrodes and the third electrodes are insulated from each other and are horizontally interlaced. The first electrodes and the second electrodes are insulated from each other and are located on opposite sides of a horizontal symmetry axis. A gain for compensating a vertical coordinate of a touch position is introduced according to capacitance variances of the first electrodes and the second electrodes.
