Abstract

The invention relates to the technical field of display, and provides a touch sensor, the touch sensor is provided with a binding area used for binding a circuit board, and the binding area is provided with at least one test pin group used for detecting the binding state of the touch sensor and the circuit board; the test pin group comprises two test pins, the two test pins are in short circuit connection through a short circuit line, and the short circuit line extends out of the binding area. The test pin group can detect the binding state of the touch sensor and the circuit board, and can also detect whether cracks occur around the binding area of the touch sensor or not.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular to a touch sensor, a touch module, and a crack detection method for the touch sensor. Background technique [0002] The touch module generally includes a touch sensor and a circuit board provided with a touch integrated circuit. The touch sensor is usually connected to the circuit board provided with a touch integrated circuit through a bonding technique. [0003] During the bonding process between the touch sensor and the circuit board, cracks are prone to occur around the bonding area on the touch sensor, and the cracks on the touch sensor are likely to cause problems such as breakage of the edge traces of the touch sensor, thus causing a series of problems in the touch sensor. Fault. [0004] In the related art, it is only possible to observe whether cracks appear around the bonding area of ​​the touch sensor through a microscope, and this detection method is time-...
