THE WALL 2 MODULE DIMENSIONS PREDICTED BY ME FIRST

[Peter CINERAMAX]

because i am the worlds leading expert on the subject matter conducting the most spectacular installation of Samsung the wall that will take years to replicate elsewhere....


i predict that it is if perfectly squared  300mm or 11" 13/16"

If not perfectly squared it is 276 mm wide by 311 mm high, or 10.87" wide by 12.23.

I bet a lifestyle subwoofer that it is indeed 300mm square.

AND FOR SOLFAR IN SAN DIEGO...

This is the new Samsung 8k Wall ...

I do not see anything here

Sorry Mat, I was referring to the above size calculation, what it would work at for The San Diego Omni PH..


As stated elsewhere, my impressions having vetted LED Walls for 3 years is such extreme hdr (5000 nits) needs to be throttled unless an outdoor application. 1200 nits is really more than enough indoors, whereas 2,000 nits is already too much. More important is the color volume, how much of rec 2020. The wall is not so good there, reaching for 8k and 16k has a color bandwidth cost on the send box. Namely the intro of color dithering.


Samsung needs to focus in making these things calibrate-able, like the SONY C-LED and the secret code name Miami Screen.


Eventually they will get it right.


Each C-LED cabinet module gets made up of 8 or 10? rectangular imager tiles. Each one of those has to be individually calibrated with a quality spectrum-radiometer. That is a lot of passes.

One must note that in principe the LED Walls are quoted at full screen brightness, like the Christe Eclipse projector, not at an 10% window or less. Being considered commercial devices they are not limited by Consumer TV energy consumption limits, yet. 5000 nits, one must consider if that is for half or a single procent of the image in specular highlights, it will not be as taxing to the human vision as full black to full white and back.

Till this year the brightness levels haven't been available to fine pitch LED displays, the thousands of nits limited to let's say 20 mm pitch and up, heat and powerdraw being the primary issues it being limited to wide pitches, application needs limiting high brightness to outdoor applications.

But in the run up to next weeks ISE show in Amsterdam  two vendors have said to show ultra high brightness at the show Danish company Expromo has developed its own Flip Chip arrangement, combined with Common Cathode, is claimed to offer 4000 nits. US Daktronics is stepping up to the plate with a whopping 6000 nits, enabled by Common Cathode and COB LED packaging.

Of course LED has always looked beautiful with bright and colourful images, the question to be answered it how they handle low voltages to the  LEDs,does the display retain its colour, contrast at the low control/addressing levels.

[Peter CINERAMAX]

The term according to the person i respect the most in the field. Is greater F-stops at the lowest levels.

[donaldk]

Yeah non-lineair remapping probably is involved I saw this in an HDR demo by LANG AG at ISE a few years ago. Remapping the 10 bit video signal to the 16 bits signal of the LED display.

[donaldk]

I should try and re-find my IBC notes. As Samsung was showing a 103 nits 1.5mm pitch led wall with camera. Standard Samsung LED wall, but dedicated control box for broadcast applications matching the LED with the rest of the studio light that they claim are around 100-103 nits. If i find them I will do an IBC report after all. With pictures.

awful panel uhd only not that clean.

[Peter CINERAMAX]

The problem is not the abundabcy of different LED panels, the problem is with over 60 of tyhem witht the satin shine, mostly made in China are not videophile grade.

[donaldk]

Satin sheen is the epoxy embedded ones From what I understand flip chips have their emitting on the front ony covered by a silicon color layer, so no or little opportunity for focussing. And fip chips, and COB or ESP, where the packaging is the size of the LEDs. Is one of the ways LED is going. There are also some vendors claiming mini-led.But in the past the term was aso misappropraited by vendors of regular fine pitch LED walls. But some now definitely will be mini-led. So we wil see.

But if they are showing that famous demoloop with all the bright reds, gold and blue they all look nice on a showfloor.

[Peter CINERAMAX]

No epoxy embedding, that is flat. I beg to differ that regular led not embedded (satin shine) look any decent. Planar, Digital Projection all other Chinese are on my Scheissen list
