A few years ago it seemed Pixel Qi was just about to blow the marked wide open (see e.g. stories on slashdot), but not much have been heard from them lately (perhaps because Mary Lou Jepsen moved to Google X). But looking at their site (although it seems to have technical problems currently), it seems that they do have products. I seem to remember that they also sold kits, so you could replace the screen on your existing laptop.
