I have some experience with this sort of thing. The panel is likely eDP and not lvds. With the data sheet, it is definately feasable to put together a custom Displayport or HDMI -> panel circuit board. Said board would also provide the power for the panel.

Looking at the link, it does mention LVDS, but I would still not believe it until I saw the data sheet

Check taobao which can easily be ordered from via yobuy.

Assuming this could be done, what are the advantages this monitor would have over available offerings?

Cool idea, if this panel is really available for only a few hundred dollars.... I'm puzzled why there isn't an existing product in the ~$1000 range you can buy. This SOUNDS like the panel that Sony uses in their http://www.bhphotovideo.com/c/product/1015238-REG/sony_pvma250_25_professional_oled.html which is obviously MUCH more expensive. If you can really source this for under $1000.... this is totally a kickstarter waiting to happen. But that's a GIANT "IF".

Infinite contrast, since the pixels in OLED go completely off.. That's the main advantage of a 60hz OLED panel.

I would buy one.
Why haven't they build one already ? Who gives a F what is costs?

A few issues off the top of my head...

The controller board needs to be programmed to be compatible with the panel.
Contact the controller mfr/supplier to see if it is suitable and can be programmed to support your panel.
Also contact the panel mfr/supplier for information on how the panel should be driven in case there are some gotchas.

The controller board needs to be HDCP compliant otherwise some equipment wont allow it to connect.
It will also prevent playback of protected media if not compliant.
Get as new a HDCP protocol board as you can to prevent the display becoming obsolete if older protocols are burned.

Maybe using vga its not need to program.

The PC connection method has no bearing on whether the panel and controller are compatible.
Whether VGA connections are available is purely down to what the control board exposes.
You wouldnt want to use VGA anyway because you will be putting the signal through a DAC and then an ADC which will reduce quality and uniformity. VGA cables can also introduce noise and timing skew.

HDCP is TRASH. It is DRM in the monitor. DRM in the monitor is BAD. HDCP should be avoided.

I agree that the world would be better without it but...

If you dont have compliance it prevents you playing protected media.
Whether that matters to you is a different matter, but the point needs addressing.
If you intend on playing back legal blu ray disks via legitimate methods, it needs to be HDCP compliant or it will error out.

Also some equipment will not allow a connection to a non HDCP display.
When I got my first HDTV, it would not connect to my 8800GT gfx card because the card lacked HDCP.
I upgraded to dual ATI 5770s and they connected fine.
Granted thats the other way round but the point stands.
It may matter to some if they ever want to connect the display to a media player that plays protected content.

Having HDCP compliance has no negative aspect unless the version is too low and they strictly enforce it with new films or hardware it connects to.

By buying a HDCP-encumbered driver board, you fill the pockets of the DRM pushers. That's a pretty major negative aspect. The movie studios chose to encumber their content and they had laws passed prohibiting consumers from removing the restrictions. They deserve $0. Complying with their HDCP lets them get away with it. There are plenty of sources for pirate movies, pirate movies will nearly always outperform online shit streams and often will be equal or better than blu-ray discs.

Look, have your own problem with it, I stated what people need to know.
Regardless of how you feel, the situation is the situation.
Take your battle to the movie studios, this isnt the place for it.

To play protected media you need an HDCP display.
That includes from streaming services.
The inclusion of HDCP support in a display is transparent to the user, it has no impact on performance or usability.

If someone is going to helm this project, then why not go all the way and contact nVIDIA for a G-Sync module?

Make the monitor super bare bones for ultra low latency and firmware simplicity.

I am actually shocked folks from BlurBusters havent built a display yet. I would definitely contribute and buy one via kickstarter if it meant the first OLED computer monitor with G-Sync.

The controller/feature/gsync/hdcp talk is all totally irrelevant until someone demonstrates you can actually source this panel from Sony in small quantities for a fraction of the cost of their professional monitor.

Why not buy 10000 units and start manufacturing "HardForum" branded AMOLED monitors marketed for enthusiasts?
Just need $50million capital to get started.

How long do AMOLED panels last now? I read an article showing how phone AMOLED screens have a rather large drop off in blue intensity after about 18 months of regular use.

This sounds like a fun project though.

I've been hearing that about blues for years, and i mean YEARS. This would be the only thing i can think of that would prevent the production of an oled monitor. If it is indeed "rather large" it could easily be the reason.

If I find a source, I will make a DVI-only unit, free from DRM and possibly 120hz+, I will also try to get black frame insertion working to kill motion blur. You all can take your DRMed up, sinked, blurry LCDs with better contrast.

Rabidz, do you think OLED can be better than your CRT?
Are all OLED screens flicker free(PWM free)?

Technology-wise: OLEDs can't change resolution or refresh rate. They are fixed-pixel and don't have the natural anti-aliasing effect. They also don't last as long. Other than that, OLED and CRT are very close. CRTs are still better; the only downside is geometry.

Monitor vs monitor: My CRT can go to 2560x1920 @ 120, which is far better than this thing. My CRT is 4:3 (proper) but this is 16:9 (excessively wide). That's in addition to the inherent technology benefits of CRTs.

Flicker is a good thing as long as it's a rolling scan or inter-frame strobe; you+need to enable black frame insertion to get it to strobe. They don't have PWM. If you don't want flicker, turn off the strobe, but be prepared for the horrible post-hold LCD blur.

25" is so small though. I would at least want a 30 or 34" screen.
