Dots on the 5K+ screen

[Frc]

@jojon

…none of which seems to be what we see here, which, as somebody said above, looks more something that reveals something about like a manufacturing process. It appears to be a tiny thing, that occur between pixels, as if the mask is thicker twixt some pixels, in periodic intervals – maybe directly relatable to routing/addressing, or possibly like some subpixels, in like intervals, fade more from the edges, with decreasing intensity, than others.

Your right it’s not mura because it’s uniform across the panel, I’ve look very closely and it’s a 2 dots dark space in a 5x5 pixel a part pattern. we can’t see them in Sebastien and voodoo captures because there too zoomed out. The image must be 100% focused to see them

The dots on the 5K+ are clearly visible.

What is strange it’s that there are not so visible on Sweviver Unit see my post, Oscar had a really bad time with his 5K+ unit

@FatalXception

They’re definitely there, visible faintly on highly zoomed pictures (and not on the 8k simmilar pics). However, as the 1 of 3 dual testers who saw them mentioned, you won’t see them in normal use, you have to be trying to find them. They’re not an issue, really more like a interesting factoid about how the panels must be manufactured.

Swivever said there are annoying in movies : “bother-me a lot, very annoying” so it’s a issue in some case.

Pimax 8K or 5K+ For Watching Movies & Videos? 3D Blu-Ray, SBS, 360 and VR Adult entertainment tested

I have checked the close up shots from @SweViver comparison video and the “dark dots” form the regular “wave” pattern. They are 5 pixels apart and 1 pixel up and down. See the pic below (taken from text readability part).

The dark spot is always on vertical line which forms the matrix substrate and it looks like what actually suffers the most are the red (or possibly blue - hard to say here) subpixels. So it is hard to impossible to spot on pure green area.

[dustyearlobe]

Would these be contributing to the blue black that there is with the 5+ maybe a shot of black screen ?

Moire and mura are distinct; Moire is the interference of layered regular patterns, while mura is unevenness within a pattern that should have been regular. For instance, the Pimax 8K’s diagonal pattern lining up with the diagonal pattern of a camera’s Bayer filter is Moire. A car queue moving in fits and starts traversing down the queue length is mura, as each driver reacts to those in front, not the overall flow. If e.g. this pattern is actually caused by some subtle overlaid pattern, like the wires in Trinitron monitors, then it could be Moire. But it looks to me more like manufacturing unevenness, the sort of thing that might lead to dead pixels in some panels.

The regularity suggests that it could also be part of the matrix, some important spots in the overall routing.

Maybe it’s emf leak?

Mura is used by the LCD industry as a synonym of moire because a lot of the manufacturers are japanese and they didn’t have a word for moire in japanese. Mura means moire, they don’t use it to mean anything else in that setting.

Using mura in english in reference to an LCD is incorrect because we do have a word for moire, its moire.

ut it looks to me more like manufacturing unevenness, the sort of thing that might lead to dead pixels in some panels.

Hum it’s seems now we have to wait and see if it’s a feature of the first batch of panels ( Engineering samples?) that can be improved by the manufacturer on the next batch or some kind of manufacturing defect/feature with this LCD in particular…

[flobv]

If they fix the dots pattern and the colors on 5K+ I am leaning towards 5K+, otherwise it’s really hard for me to digest the 5K+ or the 8K. Sebastian says the 8K is better in movies only because of better colors. I though from SweViver that the 8K is better also for the better SDE. But if SveViver says the dots pattern is very annoying in movies …

I’ve had a good hunt around the web to see if any other consumer devices have a LCD panel that displays the same pattern. Nothing. I’d be very surprised if a manufacturer would accept a panel with such a flaw. Hopefully it’s not a fundamental design issue and Pimax either somehow missed it or accepted them for preproduction units due to the time pressures. (I hope they’ve just not settled on them because they are cheap due to no other manufacturer wanting to use them!)

[flobv]

Inside a VR headset is the worst use case for a panel with such dark dots. Those dots would be practically invisible on a smartphone display.

[flobv]

By the time they reach backer number ~6000 (when I should get my Pimax) I hope they will fix this pattern.

We’ll get rev.3 versions

I had the same idea last week but didn’t take time to search thank you

[flobv]

How did you discovered that not other consumer LCD displays that pattern ?

@deletedpimaxrep1 xunshu, could you please ensure that your dev team is aware this “little” problem is making hard for some of us to really choose the 5K+ without after thoughts.

[flobv]

@deletedpimaxrep1 Please fix the dots pattern in 5K+

[NickDBaker]

Yes please stop all work on the headsets as 1 person thinks he might have possibly seen with his times 4 billion electron microscope what appears to possibly be a pattern of what might be yellow or red or green or black or maybe blank or blue or really missing dots.
