By improving blue | efficiency it could become 45%+35%+20%=100% and require only | ~2/3 of the original power and total display power efficiency | by ~50% (ignoring all the computation, RC losses, coms, etc). | | White balanced power is independent of the number of pixels (or | pixel arrangement) such as RGB vs RGGB, but RGBW or RGBY or | RGBC can improve efficiency (and reduce this relative | improvement %). | loufe wrote: | This video is a great primer on the state of the art of display | technology right now and seriously changed how I view each tech. | Seems like there is a lot of convergence between the main | technologies and they all borrow from each other in different | ways in their pursuit of the ideal display. | | https://www.youtube.com/watch?v=TyUA1OmXMXA&pp=ygUjZGlzcGxhe... | | IIRC talks about PHOLED as one of the upcoming technologies to | get to the pinnacle. | Dolototo wrote: | I'm still waiting for my affordable microled displays. | | But the last few years they became noticable used. | | This year in a outdoor it event I had to check the display wall | behind the speaker to check it out. | | It was full color, fast, bright (we are talking no cloud hot | bright summer day and that display was in the sun and it was | LEDs! | | Crazy impressive | amelius wrote: | I'm still waiting for my light field displays. | | https://www.holoxica.com/light-field-displays | | Review: | | https://www.youtube.com/watch?v=W0touQFIwns | zimpenfish wrote: | I've got a Looking Glass Portrait and it is spooky how | effective it is (although it depends a lot on the quality | of your depth map.)
