1. When the lcd display module is used to connect and disconnect the power supply, it must be carried out according to the sequence shown in the figure. That is, the signal level must be input at the positive power supply (5±0.25V). The lcd display module manufacturer tells you that if the signal level is input before the power supply is stably connected, or after it is disconnected, the integrated circuit in the module will be damaged and the module will be damaged.
2. The dot matrix module is a high-channel liquid crystal display device, and the display contrast, viewing angle, temperature, and driving voltage are closely related. Therefore, Vee should be adjusted to the optimum contrast ratio and viewing angle. If Vee is set too high, it will not only affect the display, but also affect the life of the display device.
3. The lcd display module manufacturer tells you that the display response is very slow when it is used at the lower limit of the specified operating temperature range. When the upper limit of the specified working temperature range is used, the entire display surface will turn black. This is not a damage. If the temperature range is restored, it can return to normal.
4. Press the display part hard, an abnormal display will occur, just cut off the power and reconnect it to restore.
5. When the surface of the liquid crystal display device or module is fogged, do not energize and work, because the electrode chemical reaction will occur at this time, resulting in disconnection.
6. When used in sunlight and strong light for a long time, the shaded part will produce residual image.
The above is the use and maintenance of lcd display module, I hope it can help you.
