It is recommended to consider some 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.
