Abstract

The invention provides a touch-control liquid crystal display device, which comprises a liquid crystal display screen and a touch-control screen, wherein the touch-control screen is arranged at one side of the liquid crystal display screen in an overlapping mode, and comprises a plurality of inductance units; each inductance unit corresponds to a coordinate on the touch-control screen; when a magnetic line of force passes through the inductance unit, the inductance unit generates a plurality of induced current; and the touch-control determines the coordinate of the inductance unit through theinduced current to achieve touch-control display. The touch-control liquid crystal display device has the advantages of good anti-interference performance. The invention also provides a touch-controlmethod for the touch-control liquid crystal display device.

Description

Touch control liquid crystal display device Technical field The invention relates to a touch-control liquid crystal display device. Background technique In recent years, with the development of humanization and simplicity of operation, touch display devices with touch panels, especially touch liquid crystal display devices, have been more and more widely used in production and life. Since the user can directly touch the touch liquid crystal display device with his hand or other objects to input information, the user's dependence on other input devices (such as keyboard, mouse, remote control, etc.) is reduced or even eliminated, and the user's operation is convenient. Please refer to FIG. 1, which is a schematic structural diagram of a prior art touch-control liquid crystal display device. The touch liquid crystal display device 9 includes a first substrate 91, a second substrate 92 disposed opposite to the first substrate 91, and a liquid crystal layer 93 sandwiched between ...
