6.4 The sequence of power on and off
To prevent a latch-up phenomena or the DC operation of the LCD Module, the power on/off sequence should
be accorded with the settings described in the diagram below.
The supply voltage of the external system for the Module input should be the same as the definition of VDD.
Apply the lamp voltage within the LCD operation range. When the back light turns on before the LCD
operation or the LCD turns off before the back light turns off, the display may momentarily show abnormal
screen.
In case of V
DD
= off level, please keep the level of input signals low or keep a high impedance.
T4 should be measured after the Module has been fully discharged between power off and on period.
Interface signal should not be kept at high impedance when the power is on.
While the V
DD
is off level, please keep the level of input signals low or keep a high impedance condition.
The figure of T4 should be measured after the module has been fully discharged between the periods
when the power is on and off.
