You could try, but I think it will be much too dark, it may be usable in direct sunlight but not in normal room lighting. I'm having trouble understanding the difference between looking at a light source and looking at a source of reflected light, it's still going to be light passing through the display and entering your eyes. Perhaps a warmer colored and dimmer flicker-free backlight would work? Perhaps washing the wall behind the display with soft indirect light would help? I find that reduces eyestrain for me.
