doc.no. issued date page / 13 ltn141wd-l05 11 17/oct/2007 product information 6.3 power on/off sequence : to prevent a latch-up or dc operation of the lcd module, the power on/off sequence should be as the diagram be low. (vesa recommendation) note. (1) the supply voltage of the external system for the module input should be the same as the definition of v dd . (2) apply the lamp voltage wi thin the lcd operat ion range. when t he back-light turns on before the lcd operation or the lcd turns off before the back-light turns off, the display may momentarily become white. (3) in case of v dd = off level, please keep the level of input signals on the low or keep a high impedance. (4) t4 should be measured after the module has been fully discha rged between power off and on period. (5) interface signal shall not be kept at high impedance when the power is on. power supply v dd 0.9 v dd 0.9 v dd 0v 0 v valid signals t 3 0.5 < t 1 10 msec 0 < t 2 50 msec 0 < t 3 50 msec 500 msec t 4 t 1 t 2 t 4 0.1 v dd 0.1 v dd power on/off sequence back-light 200 msec t 5 200 msec t 6 power on power off t 5 t 6 50% 50% t1 : vdd rising time from 10% to 90% t2 : the time from vdd to valid data at power on. t3 : the time from valid data off to vdd off at power off. t4 : vdd off time for windows restart t5 : the time from valid data to b/l enable at power on. t6 : the time from valid data off to b/l disable at power off.
