Digital Frames---full screen off light sensor

I didn't know where else to post this. There was no category for this.

I am wondering if anybody knows of a digital picture frame that doesn't just turn the screen to a black image when a light sensor detects that it is dark, but actually FULLY TURNS OFF THE SCREEN. The reason for this is that a so called black screen is still very bright in a dark room if one is trying to sleep. That "black" is not all that dark if the "monitor" is still displaying it.
