Samsung Develops First LCD Panel Using DisplayPort

SK writes "Samsung has developed the world's first LCD panel using the next-generation video interface — DisplayPort. Sanctioned by VESA (the Video Electronics Standards Association), DisplayPort will serve as a replacement for DVI, LVDS and eventually VGA. By using a transmission speed more than double that of today's interfaces, Samsung's new LCD only requires a single DisplayPort interface, instead of the two DVI (Digital Visual Interface) ports now used. The speed enables 2560x1600 resolution without any color smear."

      Good point. I've seen multiple posts on the internet where confused people think "dual link" DVI means it requires both of the DVI ports on your graphics card. If you look at the plug-ends of that single "dual link" cable, you realize it actually has a lot more pins packed in there than standard DVI cables!

      That was my first reaction as well. And if you're only using 8 bits per color, then yes one dual-link cable will do.
      However the display port panel in question uses 10 bits per color, which would require another cable even with dual-link DVI. As I understand DVI's handling of high bit depth displays, cable#1 would carry the most significant bits for it's half of the screen on link#1, and the least significant bits on link#2, while cable#2 does the same for it's half of the screen.

Apparently it can transmit audio data as well, so why doesn't the name at least give some sort of impression of that ability.

    The technical advantages of DisplayPort are minimal. Dual-link DVI can already do most of the things that DisplayPort does, and it has the advantage of already having decent market penetration. At first glance, I thought DisplayPort was doomed to become another in a long line of digital video standards that never caught on (LDI, OpenLDI, PanelLink, etc.). On closer examination, I think it might have a shot though.

    The importance of DisplayPort is two-fold. First, unlike DVI, it's an open standard, thus requiring no license. Second, although DisplayPort's capabilities don't have much over DVI, the way it implements capabilities does. Namely, it requires less electronics and simpler/smaller cabling, potentially making it significantly cheaper to produce DisplayPort products.

    1. Re:Hype... sort of. by bomanbot · · Score: 2, Insightful

      AFAIK Another advantage is that the actual DisplayPort connector is a good bit smaller than a DVI connector, which makes it easier to build DisplayPorts into small portable devices.

      It also helps on graphics cards, where two DVI connectors take up a lot of space and do not leave much room for other connectors. Maybe with DisplayPort it would be possible to get graphics cards with more connectors for Multiscreen Environments.

    You can quite clearly see the difference. When the screens get up to 1000 DPI, then maybe we'll have a reason to stop increasing resolution. Until then, the pixels are still way too large. Look at how much effort goes into font rendering (and it still pretty much sucks). If we had 1000 DPI screens, or even 300 DPI screens for that matter, we wouldn't need sub-pixel anti-aliasing, font hinting, etc. And things would look super crystal clear.

    I used to say the same thing about HDTV. "TV looks fine now. How much better could it be?" Then I actually saw some HDTV programs. Then I said the same thing about HD-DVD/Bluray. "DVDs are sharp, like HDTV! How much better could it be?" Then I saw some HD-DVD movies on a 1080p TV.

    It's going to be a long time before we stop having a need to increase resolution.

    We also these days have a color problem. 24-bit (8-bit per component) color seems like a lot, but it doesn't compare to even 10-bit per component color. I can't imagine what a monitor with 12-bit per component color would look let, but I'm willing to bet it'll look better than what we've got now.

    The bad news is that DisplayPort supports DRM. Both HDCP and DPCP (DisplayPort Content Protection). Like you said, it isn't mandatory yet, but future revisions of the standard will almost surely make it so, which is why I'm not in a hurry to upgrade.

    So why not just use HDMI. Here DisplayPort has a huge advantage: it doesn't require licensing fees. This means that every manufacturer in China and Taiwan could implement this overnight.

    However... implementing HDCP/DPCP does require a license fee, so if it becomes mandatory there will be a fee to pay anyway, thus negating the biggest advantage DisplayPort has over HDMI. Don't you just love DRM?

  17. It's about removing Silicon Image's lockhold by StandardCell · · Score: 5, Informative

    The short history is that VESA became a political organization unable to get anything passed through to replace analog VGA (e.g. NAVI). The Digital Display Working Group, led by Silicon Image, defined the DVI standard and never looked back, eventually defining HDCP encryption and adding onto DVI by defining HDMI. The only meaningful thing prior to DisplayPort and after analog VGA that VESA contributed to was the mounting hardware for monitors. You'll also notice that Samsung was not part of the original HDMI working group.

    The problem was that consumer electronics and computer manufacturers didn't want to pay Silicon Image skim for its patents on TMDS that's used in DVI, HDMI and the now-dead UDI. Samsung, having been left out in the cold, led the charge to DisplayPort alongside HP and a few others. They defined the open standard using PCI-Express PHY and a new link layer with lots of resolutions, audio support, and anything you could imagine. They were ready to put it out the market with its own proprietary encryption scheme called DPCP when Intel led the Hollywood charge against it. They basically said DisplayPort had to use HDCP, which was about the only concession VESA made to them. Ironically, HDCP is far weaker than the AES-128 used in the original DPCP, but they wanted it anyway and got it. Bear in mind that VESA is essentially the DisplayPort working group today. This is also the primary reason why Samsung is the first one out the gate with it.

    So, this is the product that we have today. Intel has pretty much left Silicon Image to twist in the wind. However, DisplayPort has one other use, and that's to protect the video links on a system board. Today, virtually all LCD panels use LVDS signaling, which is power hungry and requires big wide wiring harnesses between the board output and the panel input. DisplayPort was also designed for a chip-to-chip and board-to-board link so that people couldn't bypass copy protection by taking their TV's LVDS output to the LCD and building a converter board to unencrypted digital format. DisplayPort solves all of these problems plus allows for modes such as 120Hz and 240Hz panel refresh rates to combat motion blur and judder (which would require quad-link LVDS just for 120Hz at current 85MHz LVDS raw transmission rates). As a side note, Silicon Image touts iTMDS for a similar purpose, but it will never gain mass acceptance for the reasons already stated.

    It's my guess that, in the next 4-5 years, LVDS will be supplanted by DisplayPort in all the "big 5" LCD manufacturers (LG/Philips, Sony/Samsung, CMO, AUO, and Sharp). AMD/ATI, nVidia and Intel mobos/GPUs will likely adopt this on a bigger scale starting next year. The one thing that's for sure is that all of the manufacturers not aligned to Silicon Image (read: everyone) are hell-bent on pushing through DisplayPort, no matter how painful or how long it takes. And all of us will get dragged along with it.
