Panel Specification
5.7 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 below.
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 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 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 discharged between power
off and on period.
(5) Interface signal shall not be kept at high impedance when the power is on.
