Hi,

I am using the RDB1768V2 development board with the Sitronix ST637 controller and trying to blank the display during long testing periods. Currently I am using the SLPIN command to turn it OFF and SLPOUT to re-display. This works, but not completely. It seems that a backlight voltage is still applied.

Also tried the following extended sequences, but still backlight seems to be left on:

Sleep:
DISPOFF
VopSet(0,0)
SLPIN

Wake:
DISPON
VopSet(4,1)
SLPOUT

Does anyone know how this display can be completely turned off, or is this feature unavailable for this board?

Thanks
