I am inclined to agree.Chamber wrote: ↑17 Jul 2022, 14:44The last Hybrid display, the Hisense U9DG (A Duel Cell LCD TV that had 1080p IPS white and black display behind a 4k IPS colored screen) didn't last very long and has already been discontinued, so display manufacturers are going to be more reluctant to develop hybrid displays. I'm sure there would be a lot of added cost to hybridizing OLED+LCD and with NanoLED being cheaper to produce than OLED, I just can't see it working out.
I have seen the industry start rapidly tooling up for increased OLED mass manufacture, and some LCD factories shut down, so 2020s will be the Decade Of Direct-Emissive LED (OLED/MicroLED).
LCD will still be important for a long time, OLED is more motion blur efficient per Hz. While OLED Still Has Motion Blur, sample-and-hold OLED has approximately a 1.5x refresh rate advantage. This is witnessed by the fact that the brand new 170 Hz ultrawide OLEDs on the market is roughly as clear as a 240 Hz LCD. In fact, some argue slightly clearer (becuase of lack of GtG ghosting/coronas).
LCD GtG has a throttling effect on non-strobed LCD motion clarity which becomes worse as you go beyond roughly 240 Hz. The 360Hz-500Hz LCDs, while technically impressive, start falling behind Blur Busters Law (i.e. more motion blur than Blur Busters Law predicts, where for every 1ms of pixel visibilty time (MPRT100%) translates to 1 pixel of motion blur per 1000 pixels/sec.
At these 500Hz+ refresh rates, OLED/MicroLED probably now start to have a 2x sample-and-hold refresh rate advantage where a 500 Hz OLED will look preferable than a 1000 Hz LCD, when comparing the two at maximum framerate=Hz in sample-and-hold operation. This is 100% all LCD GtG’s fault, if LCD GtG doesn’t speed up any further from today.
By the end of the decade, the refresh rate race will see quadruple-digit Hz LCDs and emissive-pixeł xLED displays, but further continuance of the refresh rate race (to multi quadruple digit Hz) will probably no longer be LCD in the 2030s+.
Software-based rolling scan can then instead be done (piggybacking on a HDR framebuffer), to simulate retro displays (CRT electron beam simulation), with no more logic absolutely necessary in the display to do strobing.
A retina-Hz HDR display can utilize all kinds of software-based simulations of retro diplays (even temporal dithering simulators to mimic a DLP or plasma!), when you’ve got quadruple digit refresh rates with per-pixel HDR capability! So a 4000Hz+ LED display can simulate a CRT electron gun, plasma subfields, and DLP colorwheel + binary pixel temporal dithering.
1000Hz will get us close, but 4000Hz+ will be better because today’s DLP modulate pixels at 2880Hz, and some high end plasmas modulated at ~1440Hz (instead of 600Hz), so once we got such global refresh rates, we can simply use software based framebuffers (at the GPU end) to do the work in a GPU shader to simulate whatever display we want to simulate.
Fascinating how brute Hz can make a chamelon display possible (ability to mimic any past display). Go sample and hold and do your Windows. Go CRT electron beam simulation and play MAME. Go DLP simulation (both realtime modes and slo-mo modes, with speedup/slowdown to blend the two) to teach a classroom how DLP works. Etc. Etc.
So in the ultra-long-term, hardware-based algorithms (strobing) is destined to be obsolete. The algorithms can even be implemented as a filter in a Windows Indirect Display Driver, in a “SweetFX’ style manner.
