Serial Lcd Display Module

When the temperature decreases , the threshold voltage of theTsingtek china lcd color lcd display module will rise, increasing the drive voltage of graphic lcd display module , liquid crystal display can be realized at a low temperature . The main components of this method that the temperature sensor and adjustable output voltage and the drive voltage of the liquid crystal Serial Lcd Display Module according to the ambient temperature to allow the display to achieve the display at a low temperature , this method can make the liquid crystal display of the operating temperature range of -20 ℃ ~ +50 ℃. But the drive voltage can not raise unlimited ended , when the drive voltage is increased to a certain extent, the display contrast will be significantly decreased , resulting in a black screen monitor can not even use .
