I’m a very currious person and need to kill time waiting for my Pimax headset. I extracted the strings from the firmware (p2.dfu) found in PiTool 0.90 install folder. Here is what I found:
@Heliosurge
So both 5k+ and 8k has a 5.5“ LCD.
You did not want to believe me when I told you that it makes no logical sense to me that the 5k+ panel to be much smaller than the 8k panel. Even though Robin said 10% smaller panel…
I calculate from pixel pitch.
8k = 806 ppi
5k+ = 537 ppi(5k is 490 ppi, so 9.7% increased, oculus go =538 ppi)
5k be = 518 ppi (vive 448 ppi, vive pro 615, so I don’t hope that this oled will look great like vive pro, acer mixed = 706 ppi)
my axon7 is around 538 ppi at 5.5" display, so I can assume some pixel size, but up to the lenses magnification too (very bad on daydream2, good on mojing s1 and great on wearality).
Hold up. ANX7530 | www.analogix.com according to this it says it supports two 4k screens at 60hz. Sooo, is a 60hz native 4k mode actually feasible after all?
Interesting findings this display seems to be using RGBW matrix, but even then it would not give full QHD res.
What confuses me is the reference to SHARP LS055D1SX02, which the reference you posted suggests is used in Pimax 4K, since it has been kind of proven (by pixel shot comparisons) that the displays in 4K and 8K are not the same.
So this finally confirms that the CLPL panel is just a myth (just guessing…) , and all these panels listed, at least the ones using LCD are common LCD panels available on the market and are all working at 60Hz by default, of course Pimax could have been overdriving these to a little higher values, like in the case of the Tianma panel…but… ah ! If I now recall back all the past bitching and bullshitting about these type of panel’s refresh values that some forum people made here…puah…
I don’t think it’s 4k x 2 @ 60Hz, I think it’s 4k x 2k@60Hz… I suspect the datasheet is listed this way (pixels x pixels @ refresh) to avoid ambiguity around resolution names (i.e. 720p, 1440p, 2.5k, 4k, 5k, etc…).
Interestingly there is a chip from analogics that supports 4k x 2k @ 120hz with dual screen output: the ANX7539 (www.analogix.com). Can anybody who has a physical device and who is willing to open said device, confirm which ANX____ chip is actually on the Pimax board in the device?
We’d need to wait for someone like @Sjef to confirm the 5k+ size as pimax stated smaller panel. Which might not require tge firmware to change inside. Remember they said they were still going to sell original 5k in some markets if which case we are missing a 5k panel type.
But is interesting that the 8k is some kind if rainbow panel & doesn’t seem to look right compared to the old p4k. But this might be related to optics.
Just looking at 5k+ panel -Tiamna brand http://www.panelook.com/TL055BDXP03_Tianma_5.5_LCM_overview_32560.html
there is also 2 older iteration of this panel, but here is my question if Tiamna develop next version let say with better colors palette than can we just replace thouse panels in our homes? Will it work with current electronic ?
If it’s just a new revision it should be a drop in replacement. When a constructor makes a new revision of some component they usually stop producing the old one.
However, as you can clearly see by the screw in the upper right corner, the outer shell is not wide enough to get the inner part out. In other words, I’m pretty sure you have to split the shell open itself. That outer shell consists of 2 parts but it seems they’re just glued together. Not sure yet if I’m brave enough to try to open that part
Ok, making progress with the shell, it seems it’s not glued … In the name of science I’m going to see if I can open it without destroying my pimax 5k+, lol
