Why not sandwich two LCDs together — one B&W lower resolution, and then the 4K color one? Align them so one B&W pixel switches for the three sub pixels of RGB.

- randyrand 6y agoPeople want HDR. hard to make a brighter display by removing more light.
- TheAdamist 6y agoThey also want better black levels that oled provides. Its relatively easy to get lcds bright, but then the black level suffers. But yeah, ive read these dual layer lcds are horribly inefficient power wise.
- dungdang 6y agohow do you get blacker than 'no light emitted' when the oled pixel is off? in other words, how does a light bulb in your desk lamp produce less light than zero?
- phonypc 6y agoThese exist, called dual-layer LCD. IIRC mostly reserved for professional applications, with some consumer stuff on the horizon.
- TheAdamist 6y agoHi-sense has one coming to market. Dual layer lcd. Ive read somewhere that i cant find currently that due to the second layer its much worse energy efficiency wise than current backlit tvs and may fail energy standards from various organizations and may not be able to be sold. (EU maybe). Oled is coming down in price though, itll be interesting to see if its price competitive. https://www.cnet.com/news/look-out-oled-hisense-unveils-dual-lcd-tv-tech-aimed-at-lower-price/ https://www.cnet.com/news/look-out-oled-hisense-unveils-dual... Great idea, but i dont think id buy first gen.
