EMBEDDED TOUCH SCREEN, DISPLAY APPARATUS AND TOUCH DRIVE METHOD

摘要

An embedded touch screen, a display apparatus and a touch drive method. A common electrode layer (120) in an array substrate (100) is segmented into a plurality of sub-electrodes arranged in an array. Various sub-electrodes arranged at intervals in each row of sub-electrodes serve as touch control drive sub-electrodes (a) to form a touch control drive electrode (121), and the remaining sub-electrodes serve as common sub-electrodes (b). A touch control sensing electrode (210), a projection of which is located in an area where the common sub-electrodes (b)are located, is arranged on an opposite substrate (200). When gate lines (110) covered by each row of sub-electrodes are scanned row by row, the row of sub-electrodes are loaded with a common voltage signal (Vcom), and the touch control drive electrode (121) in the other rows of sub-electrodes is loaded with a touch control drive signal (Touch).
