When the power is off, LVDS input must be kept at either low level or high impedance.
Power sequence for Lamp(backlight) is not specified especially, however it is
recommended to consider some timing difference between LVDS input as shown above.
If backlight lights on before LCD starts function, or if backlight is kept on after LCD
stopped function, screen may look white for a moment or abnormal image may be
displayed.
This is caused by variation in output signal from timing generator at LVDS input on or
off. It does not cause damage to liquid crystal molecule and driving circuit.
