摘要
The invention discloses a touch sensor, an in-cell touch liquid crystal display panel and a liquid crystal display, where the touch sensor includes a plurality of drive electrodes and a plurality of sense electrodes intersecting each other and having mutual capacitances formed between them ; and a plurality of virtual electrodes is disposed in a remaining area other than an area occupied by the drive electrodes and the sense electrodes, and wherein the virtual electrodes are located in a same layer as the drive electrodes and the sense electrodes. The liquid crystal display panel with an in-cell touch screen according to this technical solution has better transmissivity and high screen brightness; and together with reduced parasitic capacitances between the touch sensor and the other electrodes in the liquid crystal panel than the drive electrodes and the sense electrodes, sufficiently large mutual capacitances can be obtained for detection of a touch sense signal while electrostatic effects caused by a touch of the liquid crystal display panel by an object (e.g., a finger) are eliminated.
