Then assemble the backlight assembly, after completing the production of the whole touch display screen, the touch control function needs to be tested for the last time to ensure the availability of the touch control function of the finished product.

[0032] Wherein, the pseudo piezoelectric test, also known as pre-press, is a process used in the manufacturing process of the touch screen 22 or display screen module. It is mainly used for charge-coupled device (CCD) alignment, that is, to ensure the precise alignment between the touch screen 22 and the display screen or other components during the manufacturing process. The pseudo pressure process does not involve the compression of conductive particles, so it does not directly affect the electrical performance of the product.

[0033] Based on the above structure, the conductive body 1 is provided, and the silicone conductor 11 simulating the function of finger touch is required in the conductive body 1. The shape of the silicone conductor 11 is completely suitable for all touch bridge points 21 on the touch display 2. Taking a round touch display screen of vehicle one-key start as an example, if the touch display 2 is round, the silicone conductor 11 is arranged on the circular area with the same area.
