Re: Low-persistence OLED in latest Oculus Rift prototype

Their rumored price point(s) are craaazy. I hope they offer a deluxe system with the most expensive display they can source. I'd easily pay $1000+ for it on day one.

Re: Moddable LED Backlight [for brighter strobing]

I've not read any research papers about having a max bright fast strobe and another peroid of time of dimmer lit pixels,... The Turbo240 systems double-flash with a second dimmer strobe don't they? In your Panasonic TV scanning thread I posted a paper (Video Processing for LCD-TVs) that includes a ...

Re: Panasonic pushing motion portrayal [scanning backlights]

Ah OK. ;) That forum link was a good call because the same-ish idea popped up here: I wonder if the image being distorted in real time to follow the inputs would be better (you could push the hypothesis to the point where there are as many frames as there are pixel ie "racing the beam" as Abrash or ...

Re: Panasonic pushing motion portrayal [scanning backlights]

The topic is relevant to a scanning vs strobe so no new thread really needed. The scanning I'm referring to is blanking not simply rendering output. More specifically I'm interested in how blanking the backlight can hide the tearing/shutter roll effect. Instead of rendering a whole frame and then bl...

Re: Panasonic pushing motion portrayal [scanning backlights]

Ohhhh I just had an idea regarding scanning. Need a new post for it. What if a frame was actually segmented into multiple bands and each was rendered as a slice of a unique frame and flashed as a type of sub-frame? If there are 10 bands a complete frame would be rendered like a shutter roll (if view...

Re: We need sub-millisecond persistence (<1ms) strobe backli

Dolby's HDR Dolby Vision system is pushing the number of LEDs not just for micro-dimming contrast but also for total luminance output. This is a good example of convergence as the raw resource of massive LED lighting headroom can also be used for strobing. Appropriate valuation of trade offs (light/...

Re: Panasonic pushing motion portrayal [scanning backlights]

Yep, the "240 Hz" scanning was added to a 120 Hz 2x interpolated display hence the flames about being "fake 240 Hz" displays.

Re: Charles Poynton [display visionary] - do you know who he

His website is a treasure trove of freebie tech education. I'm still trudging along digesting his papers on color/gamma science. Along with Poynton, another person that I appreciate is Alvy Ray Smith. His advocacy for progressive scan was the first to drive home the issues of display speed on pictur...

Re: Why 4k? Why not call it 2160p?

It's the non-integer scaling ratio that gets ya! This is one reason why I like the chosen Rec. 2020 resolutions. Just as one can display low framerate content on a high Hz monitor without interpolation but rather simple frame repeating, one can display lower spatial resolution content on higher reso...

Re: Panasonic pushing motion portrayal [scanning backlights]

Backlight scanning for TVs has been around for a while. About the time "240 Hz" was starting to be the buzzterm it either meant actual 4x frame interpolation or "backlight blinking" "clear motion" etc. As usual, haters at the time merely brushed it off as a "fake" gimmick. In the original Dolby Visi...
