Precaution
Please pay attention to the followings when you use this TFT LCD module.
1. OPERATING PRECAUTIONS
(1)The spike noise causes the mis-operation of circuits. It should be lower than following voltage :
V=±200mV(Over and under shoot voltage)
(2)Response time depends on the temperature. (In lower temperature, it becomes longer.)
(3)Brightness depends on the temperature. (In lower temperature, it becomes lower.)And in lower temperature, response time (required time that brightness is stable after turned on) becomes longer.
(4)Be careful for condensation at sudden temperature change. Condensation makes damage to polarizer or electrical contacted parts. And after fading condensation, smear or spot will occur.
(5)When fixed patterns are displayed for a long time, remnant image is likely to occur.
