TOUCH LIQUID CRYSTAL DISPLAY DEVICE

摘要

A touch liquid crystal display device, comprising a first substrate (51) and a second substrate (52) arranged opposite to each other. The first substrate (51) is formed thereon with a touch layer (54), the touch layer (54) is provided thereon with a plurality of drive electrodes (61) and sensing electrodes (62), and the drive electrodes (61) and the sensing electrodes (62) are constituted by a plurality of transverse metal wires (71) and vertical metal wires (72) in a staggered arrangement; and the second substrate (52) is provided thereon with a plurality of transverse drive wires and vertical drive wires, the number of the transverse metal wires (71) is smaller than that of the transverse drive wires, or the number of the vertical metal wires (72) is smaller than that of the vertical drive wires, so as to reduce a parasitic capacitance between the touch layer (54) and the drive wires, and a parasitic capacitance between the touch layer (54) and a common electrode (57), and improve the touch control sensitivity of a touch liquid crystal display device.
