Abstract

The invention provides a touch screen, a drive method thereof and a touch screen display device by applying the touch screen. The touch screen comprises a first conducting layer and a second conducting layer that are arranged correspondingly. The first conducting layer is provided with a first electrode and a second electrode correspondingly to the two side edges along the first direction; the second conducting layer is provided with a third electrode and a fourth electrode correspondingly to the second direction that is vertical to the first direction at the two side edges; the first electrode is electrically connected to a first electrode wire; the second electrode is oppositely connected with a diode in series and then is electrically connected to a second electrode wire; the third electrode is connected with a second diode in series in positive direction and then is electrically connected to the second electrode wire; and the fourth electrode is electrically connected to a third electrode wire. The touch screen of the invention has the advantages of simple structure and drive and low cost.

Description

technical field [0001] The invention relates to a touch screen, a driving method of the touch screen and a touch screen display device using the touch screen. Background technique [0002] A touch screen is set on the display to form a touch screen display device, so that the user can touch the touch screen with hands or other objects so as to input information to the display, which can reduce or eliminate the user's need for other input devices (for example, keyboard, mouse, remote control) etc.) to facilitate the user's operation. [0003] Please refer to FIG. 1 , which is a schematic structural diagram of a prior art touch screen display device. The touch screen display device 1 includes a display 16 having a display surface 160 and a touch screen 10 disposed on the display surface 160 . The touch screen 10 is adhered to the display surface 160 of the display 16 through the sealant 18 . [0004] The touch screen 10 includes a first substrate 11 and a second substrate 1...
