How to operate LCD Module?

- May 16, 2019-

The LCD module must be driven within the specified voltage range, higher than the specified driving voltage will shorten the life of the LCD module.


DC current will cause LCD degradation, so avoid using DC drive.


When the temperature is lower than the operating temperature range, the response time of the LCD will be significantly longer. When the temperature is higher than the operating temperature range, the LCD color will become darker.


The above phenomenon will return to normal when the working temperature is restored, and it is not a product quality problem.


If the display area is strongly pressed under working conditions, some characters will be displayed incorrectly, but they will return to normal after being closed once.


Condensation on the electrode terminals will cause an open circuit due to electrochemical reactions.


At the highest operating temperature, the humidity should be less than 50%RH.
