The way I thought LCD/LED displays worked was by RGB filtering a uniform white backlight. Is it only this design that does fosforescence per subpixel? Sounds way more energy efficient.
- usrusr 2y agoOh, phosphorescence per subpixel (instead of flooding all in "white" that was created through phosphorescence from blue in a central place) sounds like an awesome power optimization for where you still want/need subtractive LCD instead of some *LED with additive per-(sub)pixel emitter. For those following outdoor sports tech, I wonder if this might be the secret sauce that allowed Garmin to abandon transflective screens in the Edge 1050, which unlike their post-transflective watches is still technically an LCD. (the not secret at all meat of the change is a depressingly massive battery and big loss in runtime, but I suspect that the battery alone isn't enough to explain that the loss isn't even bigger)
