Abstract: The present invention provides a scan method of a touch signal. The different scan pulse signals with an amount corresponding to a plurality of driving lines are employed to perform scan simultaneously, and a corresponding coding is performed to each scan pulse signal; meanwhile, each of a plurality of receiving lines synchronously receives all the scan pulse signals, and a control chip is employed to decode the receiving signal received by each receiving line to determine the sources of the different signal segments in the receiving signal; as the finger touches, it is determined that the driving line corresponding to the number of the scan pulse signal is touched by the finger, and with combination of the receiving line corresponded with the receiving signal of the signal segment, of which the signal value becomes smaller, an touch position is acquired. The method can decrease an occupied period of performing scan to a touch signal by an In Cell touch control display device to increase the period of display signal scan for urging the In Cell touch control display device to be developed with higher resolution.

Abstract: A liquid crystal display device and a backlight control method thereof are provided. In response to that average pixel brightness of image data is less than a threshold, a first backlight driving signal is generated based on gray level information of the image data and a second backlight driving signal is generated based on saturation information of the image data. A convolution operation is performed on the first and the second backlight driving signal to output a backlight driving signal. The backlight driving signal is modulated and provided to a backlight module for producing backlight to a liquid crystal panel. Power consumption of the backlight module is lowered and meanwhile a dark effect caused in displaying images of a pure color is improved.

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.
