  • So, most of the marketed "LED Displays" are LCD display with LED backlight

    @Cethavi@Cethavi Жыл бұрын

    • Yep. Its fun trying to tell people that your new led display is actually a lcd display with a different light source compared to older lcd display with florescent backlight. Unless its OLED or micro-led (if they decided to use micro led directly as the pixel source and not as a backlight for an lcd display), its all lcd.

      @warmon6@warmon6 Жыл бұрын

    • Soft of. Each individual gets its own independent brightness level, instead of having a solid backlight for the entire screen. You get better contrast and color accuracy, but typically at a much higher cost than traditional LCD technology.

  • Great video ✌🏼 Small detail: when unpolarised light goes through a vertical filter, I think only the horizontal component will be transmitted (not the vertical) 😃

    @jerem_fl@jerem_fl Жыл бұрын

    • Yeah, probably a nomenclature mistake: if only the vertical component is passing, then it's because it's filtering the horizontal component; therefore it's a "horizontal filter"... but because the slits of the "horizontal filter" are actually vertically oriented, it's easy to call it a "vertical filter" because it looks vertically oriented. This stuff was easy to get confused with when studying the properties of light in high-school physics way back in my time, and I guess it still continues...

    • @@joseville yeah but like, how does it work? Like, according to this video, it would seem that just for a single pixel you'd have to manage hundreds of different inputs. It surprises me that TVs don't just glitch out randomly. We don't really think of our TVs having the same calculation power as our computers. We just see them as another appliance. But it really feels like you'd need a super computer to run all the calculations just for the display alone.

  • Regarding the LED backlight, just to get accurate black, why not make the LED backlight to also operate like old school LED screen, where dark pictures don't illuminate or partially illuminate?Granted, this doesn't solve the size limite of LED where they can only be a portion of a millimetr, but it should allow distinct blackness compared to what the usual LED shows. Is this system been done before or is not feasible?

  • OLED is by far the best display I've seen and used. by using samsung s20+ now, if I went back to using vivo y20 which has lcd 720p panel, it clearly visualize the difference between oled and lcd. The blacks are 99% black and you really can't see blacks in dark room. Colour accuracy is correct for most of daily workflow. Professional editors also use oled laptops and monitor to fullfill their accuracy demand.
