Abstract:
Disclosed are a touch panel, a method for driving the same, and a display device, where patterns for performing a touch function are integrated into a transparent touch electrode pattern layer to thereby lower in effect a research and development cost of the product, and the transparent touch electrode pattern layer can be fabricated using only an photomask, so the research and development cost is very low, and the good yield of the product is very high, thus improving the competitiveness of the product. In the transparent touch electrode pattern layer, a plurality of third touch detection electrodes are arranged among touch elements to thereby make up for a blind area of touch between the touch elements, so that both the sensitivity and the uniformity throughout the touch panel can remain constant to thereby support in effect the touch panel with an active pen. Accordingly in an active pen touch detection stage, respective first touch detection electrodes, respective second touch detection electrodes, and respective third touch detection electrodes operate as touch sense electrodes to detect a touch signal transmitted by the active pen.
