Title:
TOUCH PANEL AND DRIVING METHOD THEREFOR AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/192597
Kind Code:
A1
Abstract:
A touch panel, comprising a touch control unit (10), a plurality of driving electrodes (20) and a plurality of sensing electrodes (30). The plurality of driving electrodes (20) and the plurality of sensing electrodes (30) are all electrically connected to the touch control unit (10). The touch control unit (10) provides a driving signal to each driving electrode (20) and can also provide a sensing signal to each sensing electrode (30). The driving electrodes (20) and the sensing electrodes (30) are disposed in an insulated manner. The plurality of driving electrodes (20) and the plurality of sensing electrodes (30) extend in the same direction. Resistances at different positions of the driving electrodes (20) are different in the extending direction of the driving electrodes (20). The sensing electrodes (30) can output sensing signals to the touch control unit (10). Also provided is a display device comprising the touch panel. Because the driving electrodes (20) and the sensing electrodes (30) extend in the same direction, lead wires of the driving electrodes (20) and lead wires of the sensing electrodes (30) are located on the same side, and therefore narrow bezel display of the display device comprising the touch panel can be achieved.
