The application is developed by a Chinese researcher and relates to the technical field of touch display screens, in particular to a touch sensor. The newly developed touch sensor incorporates a sensing electrode, sub-sensing electrodes arranged in an array, and a sensing electrode leads arranged between two adjacent sub-sensing electrodes and attached to the sub-sensing electrodes. The projecting portion of one of the two adjacent sub-sensing electrodes and the recessed part of the other of the two adjacent sub-sensing electrodes are arranged in an equal manner. The touch sensor does not require a complex process such as bridging, which can efficiently decrease the risk of breakage of the sensing electrode pattern and its leads during bending while improving touch sensitivity and overcoming the distinctness of the sensing electrode design.
