The main tools for LCD screen assembly are hammers and wrenches, which are used to tighten the frame feet. The sequence of assembly operations is to place all tools and raw materials on the workbench in an orderly manner. Secondly, place the shell correctly on the workbench according to the instructions on the process card. If there is assembly tooling, place it on the tooling as required. Pay attention to the correct direction of the shell. Next, remove the protective film of the LCD screen and wipe the electrodes clean with dust-free paper. After confirming the direction, follow the instructions on the process card and put them into the case correctly. Take out the circuit board. If you want to add a backlight, fix the backlight on the PCB first.

Align the circuit board to the frame position according to the instructions on the process card, install it into the shell and press the zebra strip, and use assembly tools to fix the shell and circuit board. Be careful to twist the frame legs to a 45° angle, do not chew the board or break the wires, and make the frame and PCB board in parallel contact. Remove the assembled finished product from the workbench, apply a protective film, and place it on the turnover tray. Pay attention to make the screens face each other and the boards face each other to avoid scratches. After the product is assembled, submit it to the inspector for inspection. If it fails, reassemble it.

LCD The purpose of LCD screen assembly is to make the screen and circuit board electrodes correspond one to one so that they can complete the electrical performance matching. However, since the screen is not in direct contact with the circuit board, and the conductive tape is used as a medium, the screen and the board cannot visually correspond, so that the corresponding electrodes cannot correspond to each other, causing misalignment. The corresponding electrode connections between the screen and the circuit board during the assembly process are called alignment. During assembly, the correspondence between the screen and the board during assembly is mainly achieved through the alignment of the screen and the board, and the alignment of the shell and the board. . As an intermediate medium and as the corresponding standard between the screen and the shell, the shell plays a big role in alignment. Alignment methods mainly include side alignment, alignment and middle alignment.
