TFT LCD screen welding precautions


Since the viewing angle of TFT LCD screen display is changed with VLCD, we should adjust VLCD so as to display the optimum contrast. Driving an TFT LCD screen within a specified voltage limit range is essential for higher voltages and then limiting leads to shorter TFT LCD screen lifetimes. Since the electrochemical reaction of direct current leads to the adverse deterioration of TFT LCD screen, the use of DC current should be avoided driving.

When the temperature is lower than when running, the response time will be extremely delayed in the temperature range and on the other hand at higher temperatures the TFT LCD screen shows darker colors for them. However, these phenomena do not mean that the TFT LCD screen breakdown or out of order, it will return at the specified operating temperature.

If you press the display area hard during the operation, the display becomes abnormal. However, if it is closed and then turned on, it will return to normal. A slight dew on the terminals can cause the electrochemical reaction terminal to open circuit. Use at maximum operating temperature, 50%RH or lower.

The TFT LCD screen drive voltage is turned on when an analog high voltage is applied before the input logic voltage is applied. When the module is powered off, the analog high voltage is removed before the logic voltage. Each signal is input after the positive/negative voltage is stabilized. Please keep the temperature within the specified use and storage range. Polarization may degrade at high and high temperatures, bubbles are generated or the polarizer peels off high humidity.

Safety recommendations crush damaged or unnecessary TFT LCD screen into pieces and rinse them clean using solvents such as acetone and ethanol, which should be incinerated later. If any liquid leaks out of the damaged glass pool and comes into contact with hands, wash and dry thoroughly with soap and water.
