Could an E-ink screen behind the backlight of an LCD screen be used to enhance the dynamic range of the screen? The idea being to modulate the local brightness of the screen by changing the color of the e-ink.
- luka-birsa 6y agoThe screen really does not let a lot of light shine through. There is a reflective coating (imagine aluminum foil) that reflects back. We did try to use the opacity of screen with high power leds for some usecases but it did not work. I think you need to look at E Paper optical characteristics as you would look at 1 mm thick cardboard. The best way to fix optical characteristics is to play with the substrate and layers in front. Like adding a very good frontlight really helps with contrast even in non-dark conditions.
