I apologize for not reading those papers first, but I don't see how this is possible. With miniLEDs you have a small area of the screen which has a single backlight - if half of that area is 100% white and half 100% black, you'll need the backlight 100% on.
How can that black be as black as in the neighboring area where the backlight is off?
- ericlewis 4y agoI read the papers - it can't, they just seem to have novel ways of controlling the zones available. I supposed the smaller the miniLED array the more control you can have over the zones and the better it works. But there doesn't seem to be anything that really solves the bleeding issue.
- opwieurposiu 4y agoThe human eye perceives colors relative to their surroundings, so a black pixel next to a white pixel will look blacker. You can exploit this effect to enhance the perceived contrast ratio. How well this works in practice varies. https://en.wikipedia.org/wiki/Checker_shadow_illusion https://en.wikipedia.org/wiki/Checker_shadow_illusion
