What They Say
I had put aside a Digitimes article about a new 8K 32″ panel for professional monitors from AUO. I was just about to dig into it when I saw that Chris, with his 8K Association hat on, had dug into it. AUO gave him these specification details.
| Resolution (pixel) | 8K (7680 x 4320) |
| Frame rate | 60 Hz |
| Brightness | 720 cd/m2 (typical) |
| Color Gamut | Adobe RGB 100%, DCI-P3 99% |
| Contrast | 1,000 : 1 |
| Viewing Angle (U/D/L/R) | 89° / 89° / 89° / 89° |
AUO also said that the backplane of the monitor is based on LTPS and uses AUO’s A.R.T. (Advanced Reflectionless Technology) non-glare and non-reflection process.
In its article, Chris discusses the measurement of contrast in different ambient conditions and points out that IDMS 1.03 defines how to measure the contrast, but doesn’t define the environment for testing.
What We Think
The use of LTPS is interesting. As far as I know, this is the biggest LTPS panel that has been put into mass production (if a reader knows otherwise, please let me know). I would assume that the technology was used to maximise the aperture ratio as otherwise, the power consumption of the display would probably be excessive. The 8KA expressed surprise that refresh rates above 60Hz were not supported. I’m not sure that there are currently graphics cards that could drive much higher refresh rates (but again, I’m happy to be updated).
The discussion about viewing conditions reminds me that in the TV world, ‘standard viewing conditions’ were defined for testing purposes and I remember many (many) years ago that a UK University (Bradford if I remember correctly) had a suite that could be used for testing. It would be a move forward for the industry if there were such standard conditions for the measurement of ambient contrast for desktop monitors, but establishing those conditions would not be trivial.
Chris asked if ViewSonic was the lead customer for the panel as it announced a monitor at CES. We were approached and offered an interview about this a few weeks ago. However, things have gone quiet since we sent some questions about the monitor. It’s time to remind them!
In digging back about Bradford, I was reminded that the National Media Museum is based in Bradford. I must arrange a visit when lockdown is over as I don’t think I have ever visited it. (BR)
