1. The LCD screen should not be stacked.
Most dot matrix LCDs have high voltage circuits stacked behind them. On the back, dots, lines, and planes work together to form the display, but if the LCDs are stacked together, some bits and pieces may crack or be damaged. Therefore, in order to prevent the adverse reaction of the LCD screen, do not stack the LCD screen.
2. Avoid high voltage when connecting the LCD screen.
According to market research, dot-matrix LCD displays have many advantages, such as low energy consumption, accurate image restoration, and zero radiation. Therefore, it has been widely used in many fields, but it is necessary to avoid heavy pressure in the actual disassembly and connection operation, because the heavy pressure will be transmitted to the fragile TCP part of the LCD, causing the TCP part to break or other accidental damage.
3. Disassembly and assembly should not be carried out when the power is turned on.
The backlight connection line of the dot matrix LCD liquid crystal display is usually in front of the LCD, and the connector of the backlight sometimes scratches the surface of the polarizer during disassembly and assembly. Therefore, many professional manufacturers remind users not to disassemble the LCD screen when starting up.

The powerful dot-matrix display function of the dot-matrix LCD screen has been widely recognized and verified by more and more consumers and sales markets. Especially those dot-matrix LCD displays with low energy consumption are expanding their application range. The disassembly and assembly of dot-matrix LCD displays should not only avoid stacking, but also avoid greater stress when connecting LCD displays. Remove and install when connected.
