The use and maintenance of the LCD module

(1) module to access the power and disconnect the power must be in the positive supply (5 ± 0.25V) stable access to the input signal level. Such as the power supply is stable then in front of people, or disconnected after the input signal level will damage the integrated circuit module, the module damage.dot matrix LCD module

(2) dot matrix liquid crystal display device module high ones, the display contrast, viewing angle and temperature, the drive voltage relationship. So should be adjusted the Vee to best contrast, viewing angle stops. If the Vee adjustment is too high, will not only affect the display, but also shorten the life of the liquid crystal display devices.

(3) when the specified operating temperature range below the lower limit, the display response is slow, but when used in the upper limit of specified operating temperature range, the entire display surface will be darkened, which is not damaged, just restore the predetermined temperature range, everything will resume summer normal.QVGA LCD module

(4) push hard parts, will produce abnormal display. Then cut off the power to re-access can be restored to normal.

(5) When the liquid crystal display device or module surface fogging, do not energize work, because it will cause the electrode chemical reactions, resulting in disconnection.

(6) Long-term for the sun and bright light will cover parts of residual images.
