11 6.3 Power ON/OFF Sequence : To prevent a latchup or DC operation of the LCD module, the power on/off sequence should be as the diagram below. Power Supply VDD 0V 0.9 VDD 0.9 VDD 0.1 VDD 0.1 VDD 0.5 T1 10 msec 0 T2 50 msec 0 T3 50 msec T1 T2 T3 T4 500 msec T4 Signals VALID 0 V Power On Power Off Backlight 200 msec T5 200 msec T6 50% 50% T5 T6 Power ON/OFF Sequence 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. NOTE. (1) The supply voltage of the external system for the module input should be the same as the definition of VDD. (2) Apply the lamp voltage within the LCD operation range. When the backlight turns on before the LCD operation or the LCD turns off before the backlight turns off, the display may momentarily become white. (3) In case of VDD = 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 discharged between power off and on period. (5) Interface signal shall not be kept at high impedance when the power is on.
