Some technical info about 8k/5k extracted from the firmware

I wouldn’t give too much on CLPL technology. Chinese firms love to throw around such words. Brainwarp anyone?

I don’t really care either. We got LCD panels without ghosting and with good refresh rates. They deliver what’s promised. Let them call it CLPL or whatever. Unless proven wrong I am sure they use simply off the shelf displays and overclock them. Who would produce a new revolutionary technology for a small firm that manages to produce 30 to 40 HMDs a day?

Samsungs blur filter on the Odyssey + would’ve been called ULTRA OLED in chana for sure.

I wish people here would just call them what they are: LCD panels (with a firmware tweak to achieve low persistence).

You prefer “1233 PPI level” over CLPL?:joy:

You mean like Led Tv vs lcd? :beers::wink::+1::sparkles:

Quoting your post:

In fact it sounded a bit mismatch and confusionary to me too :slight_smile: Maybe you was intending pixel refresh or pixel persistence, so be sure to not mix or interchange terms because any of these has a completely different meaning :smiley:

It’s nothing new mate…it’s the same that has been used with Lightboost or other techniques to reduce various artifacts and blurring, nothing to do with CLPL panels, that in reality are just overdriven Lcd panels like I already mentioned, panel overdrive could be done easily even on recent Pc monitors with just an utility and knowing what you are doing.

But again, if you overdrive a panel, or use some software algorithm, only some aspects can be improved, while other will worsen out, it’s a complex situation, and only future faster panel tech could solve this, certainly not these CLPL or anything existing currently.

Like @Thoemse said, it’s very possible that the term has just been invented by Pimax, Chinese merketing…ah !..

Or Samsung’s anti sde displays. :wink: Sony already used a similar technique & didn’t name it.

As Oculus too did (the Rift have a diffusion filter)

Not really, that Oculus filter is on the lens and is not part of the OLED panel assembly.

Regarding pixel density not my comments but it’s a comment In the link pasted . Seems like my comment tought

How can you say that since we do not know what is a CLPL panel? The point was saying it seems pimax is not doing really much with those commun panels that they all claim to be CLPL. So VBI=CLPL even if it’s not new in general. Seem new in VR has analogix just officially include this feature in their last chips

So …

  • How will colors and blacks/whites improve in 5K + if this is limited by screens?

Gamut color:
5k+: 70% NTCS (100% NTCS = 90% sRGB)
8k: 130% sRGB

Contrast ratio:
5k+: 800:1
8k: 1200:1

  • Why is there no information about the components (or screens) of the 5K BE in the firmware?

  • Why (according to Pimax) the 5K BE only arrives up to 83-85Hz, it has 15ms or more of input lag and nothing is mentioned of BrainWarp if it is handling the same resolution as the 5K+?

I know that the input lag in OLED panels is higher than in the LED panels (LCD, IPS, QLED…) but the difference is not much (20ms vs 15ms) for the year 2017 but they have been improving year after year exceeding the 15ms barrier as indicated, but the response time is incredibly lower in the OLED panels than in the LEDs.
Could not mount AMOLED high PPI/PPD screens with local dimming (albeit with few LEDs) to improve the color volume as well as the levels of brightness and black? Or mount QLED screens?

If there was a way to change the screens by the Samsung Odyssey+ (or mount an extra layer to eliminate the SDE of the screens), the ideal HMD would be the 5K BE by high FOV, SDE eliminated, wide colors and contrast, absolutely trampling all the HMDs that there is in the market. It would be a VR HMD killer.

I personally have been following this project for years but I have not been a baker. I wanted to get the 8K but the issue of the bad climber that leads (or the bandwidth) that reduces image quality pulls me back.
The 5K+ seems a good option if it were not because the levels of color and contrast do not even reach the sole of the 8K shoes. The only option that I see valid is the 5K BE, but without anti SDE layer… Or an 8K with 4K OLED screens that would give the option to use a native scaler or resolution (as a conventional 4K TV does).

I do not even mention the subject of the dirtorsiones of the lenses in the highest FOV (we can ignore it), but the theme of the screens, colors, contrast and SDE does have me doubtfully.

Colours can improve with customization settings. You can buy a TV for example, and customize it the way you like it. Better blacks, but overall dimmer? Warmer tones but loose some of the contrast? Higher saturation setting on colours, but the odd ‘off’ colour or tone? Like the difference between a home theatre projector, a home theatre projector after professional calibration, and then the same after the owner tweaks it to their liking.

That having been said, you won’t ever be able to close the gap if certain aspects of the specs are inherently higher with the 8K over the 5K+, at least not without a large compromise to another aspect of visual quality, but unless you’re sitting side by side comparing the two, after you’ve had one or the other on your head a while, you are unlikely to be focusing on such things.

I think the SAMSUNG AMS567JD09 is the 5k BE screen.

Then no wonder Rift has so much godrays, lol.

the relevant questions are whats the panel in the 8k and whats the scaler, the first one is also important to judge/estimate if the panel is a option for the 8k-x, if the subpixel count is to low (like rgbg) then the 8k-x is no good from the start (the 8k-x might be pointless anyway as there is no single gpu capable of using a 2x4k hmd)
the 5k+ is fine and the only thing to be done is the color adjustment (if possible) and maybe night mode

anyone with a 8k brave enough to open the housing and have a look about the panel(s)?

One of the members here has taken it down partially. But it was labor intense to get to the part numbers on the panel. Unfortunately they couldnt be seen from a partial tear down

8kx will be similar to 8k, it’s 80hz and both headsets work with resolution close to 4k (supersampled Vs native). The difference may be the clarity, although 8k compensates through supersampling - it won’t have same clarity as 5k or 8kx.

With proper asw or brainwarp 8kx will become superior.

The panel info as per @Sjef teardown compare to firmware poke suggests panel model is unlikely to help. As his 5k+ panel doesn’t seem to match & searches yield no results in searches.

Suggesting custom panels not listed.

My understanding is that the panel is 90 Hz and that the scaler chip in the 8K is what limits it to 80 Hz (so the 8KX should be able to run at 90 Hz).
