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.

Abstract: The present application discloses a touch substrate including a base substrate; a black matrix layer on the base substrate in a black matrix area of the touch substrate; and a touch electrode layer on a side of the black matrix layer distal to the base substrate in a touch electrode area of the touch substrate. The touch electrode area partially overlaps with the black matrix area thereby forming an overlapping area. The touch electrode layer includes a plurality of touch electrode blocks at least partially in the overlapping area. A touch electrode block at least partially in the overlapping area is spaced apart from adjacent touch electrode blocks by a first gap. The black matrix layer in at least a portion of a region on a side of the first gap proximal to the base substrate has a reduced thickness relative to a thickness of a remaining portion of the black matrix layer.
