TOUCH SCREEN AND DRIVING METHOD THEREFOR, AND DISPLAY DEVICE

WIPO Patent Application WO/2017/067318

A1

A touch screen and a driving method therefor, and a display device. The touch screen comprises a fixed electrode (4) arranged on one side of an array substrate (1) away from a colour film substrate (2); the array substrate (1) comprises an underlayment (11), a plurality of sensing lines (12) arranged on the underlayment (11) and a plurality of common electrodes (13) arranged in a matrix; orthographic projections of the sensing lines (12) and the fixed electrode (4) on the underlayment (11) are overlapped on orthographic projections of the common electrodes (13) on the underlayment (11); an extension direction of the sensing lines (12) is parallel to a column direction of the arrangement of the common electrodes (13); some of the common electrodes (13) are used as first driving electrodes when pressure sensing touch control is performed; sensing lines (12) corresponding to the remaining common electrodes (13) are used as sensing electrodes when the pressure sensing touch control is performed; and the fixed electrode (4) is used for assisting the first driving electrodes and the sensing electrodes to detect a touch control pressure when the pressure sensing touch control is performed.
