Abstract: The present disclosure relates to a display panel and an array substrate including a plurality of pixel cells including colorful sub-pixels and one white sub-pixel. Each of the sub-pixels includes at least one sub-pixel electrode and at least one sub-pixel transistor corresponding to each of the sub-pixel electrode. The sub-pixel transistors are configured within the white sub-pixel to enhance an aperture rate of the colorful sub-pixels. As the sub-pixel transistors are configured within the same white sub-pixel, the brightness of the white sub-pixel may be decreased. At the same time, the aperture rate of the colorful sub-pixels may be greatly enhanced so as to enhance the performance of colorful images.

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.
