Abstract
A capacitive in-cell touch screen panel and a display apparatus are disclosed in present disclosure. At least one touch control inducting electrode is disposed on the color film substrate and at least one touch control driving electrode is disposed on the TFT array substrate. Each of the touch control driving electrodes overlaps with multiple sets of gate lines in the TFT array substrate, respectively, and each of the touch control driving electrodes comprises touch control driving sub-electrodes disposed along the row direction and a driving control unit is disposed at the connection of each of the touch control driving sub-electrodes and each set of gate lines. Since the driving control unit is able to release the display driving signal delivered by the gate line after it is loaded to the touch control driving sub-electrodes, which is equivalent to the situation where a driving pulse is loaded on the touch control driving sub-electrodes, so that the multiple sets of gate lines overlapping with the touch control driving electrodes input the touch control driving signal sequentially to the touch control driving electrodes through the driving control unit, and thus a plurality of dr…
