Power ON/OFF Sequence

Note (1) The supply voltage of the external system for the assembly input should follow the definition of Vcc.

Note (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

abnormal screen.

Note (3) In case of Vcc is in off level, please keep the level of input signals on the low or keep a high

impedance.

Note (4) T4 should be measured after the assembly has been fully discharged between power off and on period.

Note (5) Interface signal shall not be kept at high impedance when the power is on.
