6.2 POWER ON/OFF SEQUENCE
To prevent a latch-up or DC operation of 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 Vcc.
(2) Apply the lamp voltage within the LCD operation range. When the backlight turns on before the LCD
operation of the LCD turns off before the backlight turns off, the display may momentarily become abnormal
screen.
(3) In case of Vcc = 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.
(6) CMO won’t take any responsibility for the products which are damaged by the customers not following the
Power Sequence.
(7) There might be slight electronic noise when LCD is turned off (even backlight unit is also off). To avoid this
symptom, we suggest "Vcc falling timing" to follow "t7 spec".
