Power sequence for Backlight
timing difference between LVDS input and Backlight input as shown above.
If the Backlight lights on before LCD starting, or if the Backlight is kept on after LCD stopping, the 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 the damage to the LCD module.
