Title:
TOUCH LIQUID CRYSTAL PANEL AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2016/106849
Kind Code:
A1
Abstract:
A touch liquid crystal panel and a manufacturing method therefor. The touch liquid crystal panel comprises a sensing layer and a wiring layer. The sensing layer comprises a plurality of electrode areas (210) that are arranged in an array mode. The electrode areas (210) are electrically isolated from one another and respectively correspond to a plurality of pixel units in a display area. The wiring layer comprises a plurality of wire harnesses (230) that are electrically connected to a control chip. Each electrode area (210) is in electrical contact with the corresponding wire harness (230) in the wiring layer through a via hole (220) formed at some sub-pixels in the corresponding pixel unit, so that the control chip can obtain sensing signals in each electrode area (210). The electrode areas (210) in the sensing layer are in electrical contact with the wire harnesses (230) in the wiring layer by arranging the via holes (220) only near some sub-pixels, and the aperture ratio of a self-capacitance display screen is increased by reducing the number of the via holes (220), and meanwhile the transmittance of the whole panel can be improved.
