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.
