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.

Abstract: The present invention provides a touch scan drive method. The discrete touch scan is implemented as the touch display panel is in the standby state or the normal display without touch state. Namely, the touch scan pulse signal is merely transmitted to a portion of the emitting electrode in one touch scan, and the signal transmission number is decreased. As the complete touch scan is implemented as the touch display panel is in the touch state, the power consumption of the touch display panel can be reduced under the premise without influencing the normal work and scan precision of the touch display panel.

Abstract: A driving controlling method of liquid crystal panel pixels and a liquid crystal panel are disclosed. The method includes: a charging period being configured for switching one frame of the liquid crystal panel, and at least one charging period comprises a high-voltage charging phase and a voltage correction phase. Voltage amplitude within the high-voltage charging phase is larger than a predetermined voltage amplitude such that the liquid crystal panel pixels accumulate an amount of electricity within a shorter time period. The voltage amplitude within the voltage correction phase equals to a default voltage such that the voltage is precisely configured to be the default voltage. In this way, the liquid crystal panel pixels may quickly reach a default voltage so as to enhance the display performance of the liquid crystal panel.
