When different modes are selected in the ESD test process, the touch display integrated module is placed in different modes, sometimes the cover plate is required to face upwards, sometimes the cover plate is required to face downwards, and different module placing modes lead to different angles of the electrostatic gun discharge head. The ESD test specification requires contact discharge and air discharge, and the contact discharge requires that the electrostatic gun head needs to contact an object to be tested; air discharge requires that the electrostatic gun head is at a certain distance from the object to be tested, so that the height of the electrostatic gun head from the object to be tested needs to be changed along with different test modes. In the process of carrying out ESD test on a display module in the prior art, the following problems exist: 1. the tester needs to hold the static gun for a long time, and the labor intensity is high; 2. because the static holding mode is adopted, the shaking problem exists in the testing process, and the problem of testing potential deviation can occur; 3. there are many ineffective actions in the test process, such as placing the electrostatic gun, picking up the electrostatic gun, etc., so that the test efficiency is low.
