(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 turn on)becomes longer. 4) be careful for condensation at sudden temperature change. condensation make damage to polarizer or electrical contact part. and after fading condensation, smear or spot will occur. 5) when fixed pattern are displayed at long times, remnant image is likely to occur. 6) module has high frequency circuit. if you need to shield the electromagnetic noise. please do in yours. datasheet 4 .com u

(tft/lcd and lamp are made of glass) please wash hands sufficiently when you touch the liquid crystal coming out from broken lcds. 2) as it is possible for pcb or other electronic parts of module to small to smoke and to take fire becauseof the short circuit. please design the circuit of your instrument not to flow the electric current to tft/lcd module more than 500ma. (by apply the fuse for example) 3) as back-light unit has high voltage circuit internal, do not open the case and do not insert foreign materials in the case. datasheet 4 .com u
