Please do not input Vsync/Hsync to this module,it is recommend to be used by the pull-down
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
