Abstract: A driving control method is disclosed. The method includes steps of sequentially turning on the first color sub-pixel, the second color sub-pixel, the third color sub-pixel and the white color sub-pixel respectively in the first time period, the second time period, the third time period, and the fourth time period in order to respectively input grayscale values of the sub-pixels using the source driver. Wherein, when using the source driver to input the grayscale vale of the white color sub-pixels, the source driver decreases a preset value of gamma voltages of the white color sub-pixels such that the preset value of gamma voltages when inputting grayscale values of the white color sub-pixels is less than a preset value of gamma voltages when inputting grayscale values of the first color sub-pixels, the second color sub-pixels and/or the third color sub-pixels. Through the above way, the display quality can be increased.

Abstract: The present invention proposes a touch panel display device and an array substrate. A touch panel display device includes a touch detecting circuit, touch detecting electrodes, and transmission paths. One terminal of each of the transmission paths is connected to one of the touch detecting electrodes, and the other terminal of each of the transmission paths is connected to the touch detecting circuit, for transmitting a touch signal of the touch detecting electrode to the touch detecting circuit. A difference of variation for each touch signal of the touch detecting electrodes is smaller than a first predetermined value after being transmitted through each of the transmission paths. The first predetermined value is a threshold by which false identification occurs among the touch signals from the touch detecting electrodes. The present invention improves sensitivity of touch.
