PCWorld: OLED and 4K at CES 2013: The fantasy and the reality
On an OLED HDTV, colors pop like nothing you've seen before. There is no blacker black than the black you'll see on an OLED TV, and colors look vivid and twinkly against that pitch-black background. You also get ultra-wide viewing angles. Because of the display's fast response rate, fast motion looks fluid on the screen, and 3D content looks amazing. OLED TVs don't need a backlighting system, so they're the thinnest HDTVs on the planet; LG's first OLED set is less than 0.16 inches thick. An OLED display can also be malleable; both Samsung and LG showed off curved prototype OLED sets at CES 2013.
if you want to thoughtfully examine the intricacies of a high-resolution image or read a book on your TV screen, you want a 4K TV. If you want your face pleasantly melted off by a majestic festival of light, OLED is the way to go.
A TV can be both a 4K and an OLED set, just like a 1080p TV can also be a plasma or LCD set. In fact, there were two 56-inch 4K OLED prototypes at the show: one from Sony, and one from Panasonic. The combination of tack-sharp 4K resolution, outstanding contrast, vibrant colors, and smooth motion exhibited by these prototype sets made my shoes fall off.
Universal Display (UDC) is an OLED research company, and one of the field's pioneers. UDC is involved in OLED IP, and holds many patent related to the commercialization of phosphorescent based OLEDs and also flexible, transparent and stacked OLEDs - for both display and lighting applications. The company offers both emitting and host materials.
UDC licenses its OLED production IP, and also sells OLED chemicals. UDC lists Samsung, CMEL, LG, Pioneer, Panasonic Idemitsu OLED lighting and Konica Minolta as its licensees. UDC is working with many other companies, including Sony, DuPont and Novaled. Back in 2009 UDC claimed that "virtually All AMOLEDs on the market use our technology".
