The invention provides a touch-control liquid crystal display device comprising a sensing electrode, a first scanning line, a touch-control line, a transistor and a control electrode, wherein the transistor comprises a grid electrode, a source electrode and a drain electrode, the grid electrode is electrically connected with the first scanning line so as to receive a scanning signal, the source electrode is electrically connected to a contract electrode, the drain electrode is electrically connected with the touch-control line, and the sensing electrode and the contact electrode together define a pressure control switch which responds the external pressure to electrically connect the contact electrode and the sensing electrode so as to electrically connect the source electrode and the sensing electrode. The touch-control liquid crystal display device has the advantages of thin thickness, light weight, high permeability and good display effect. The invention also provides a driving method of the touch-control liquid crystal display device.
Description
technical field [0001] The invention relates to a touch liquid crystal display device and a driving method thereof. Background technique [0002] In recent years, with the development of humanization and simplification of operation, touch liquid crystal display devices with touch screens are more and more widely used in production and life. Since the user can directly touch the touch-sensitive liquid crystal display device with hands or other objects to input information, thereby reducing or even eliminating the user's dependence on other input devices (such as keyboard, mouse, remote control, etc.), which greatly facilitates the user's operation. [0003] At present, touch screens usually include resistive, capacitive, acoustic, infrared and other types, which are generally in the form of rectangular transparent panels, which are arranged on the display side of the liquid crystal display device in a stacked manner, and are connected through a flexible circuit board.
