Abstract: A touch sensing device is provided. A shielding plate is provided for covering and shielding wires that route sensing electrodes to a flexible circuit board. Alternatively, a conductive layer of the circuit board is applied for shielding a plurality of contacts of the electrodes and wires. Wires that couple two same typed electrodes extend as a shielding plate for shielding contacts of another type of electrodes. An auxiliary electrode bordering outside the sensing electrodes can be provided to compensate fringe effects of the sensing electrodes.

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.
