Good news: In order to achieve a consistent uniformity across the entire surface of the screen, Panasonic performs a Mura correction / Factory calibration of each flagship GZ2000 panel.

"The de-mura system includes a signal generation unit, an image pickup unit and a control unit. The signal generation unit display test pattern on the OLED screen. The image pickup unit including a high resolution 2D matrix chromameter can capture CIE 1934 XYZ of each OLED pixels and distinguish the uneven light output of each pixels. The control unit control the entire system procedure and generate luma correction data to make screen uniform and color correction data to let screen output true color. Both brightness correction data and color correction data will be compressed and save inside the display memory. Display control circuit uses these correct data to realize de-mura function.
Such kind of technique is based on the idea of capturing the images of the panel in different colors and grayscale, followed by the calculation of the intensity distribution of Mura. And then it is converted into the compensation data which TCON can read, and finally the TCON restores the images in real-time."

Apparently, Sony also performs a factory calibration on its Master Series TVs.

This factory calibration, currently perfectible, must become common practice!
No more panel lottery!

[Geoff D]

It should be "common practice" if you're paying 4 grand a time, sure. For anything that's moderately priced then it's not going to happen.

[DanBa]

Agreed! The cost of the factory calibration process will come down with time.

Pretty cool. We all love scientific data; and no, Blu-ray forum* didn't make it in that top group.
But the HDR Discussion Thread might one day ...

Someone on AVS also put one up. Maybe he was second.

It's not 8K? That means it's practically worthless, amirite folks?

3 days to install? Lol

And that's exactly why Samsung display is moving towards Quantum Dot Oled instead of micro led.

In other words, some of those mosquitos people may be seeing in their favorite old movies on home deliverables may not only be attributable to grain (good), but also film scanner noise (bad, as in completely needless).
