Samsung displayed their latest development in OLED display technology with a 40-inch Full HD OLED display and a flapping 0.05mm thick OLED at IMID Korea. Samsung claims that it is the world’s first company to show a prototype 40-inch OLED display capable of 1920 x 1080 (1080p) resolution. Samsung started development of the 40-inch OLED in 2005 and showcased an OLED display with 1280 x 800 resolution and 5,000:1 contrast ratio. The new panel has a 1,000,000:1 contrast ratio. Along with 40-inch screen, Samsung also showed 14-inch and 31-inch OLED prototypes.
The other important prototype that Samsung showed was a 0.05mm thick, 4-inch OLED panel. Samsung named it “flapping display” because the display was flexible enough to flutter in breeze of air. To achieve the thinness Samsung developed a new membrane sealing technology that replaces glass substrate normal used in OLED displays. The display has 480 x 272 resolution, 100,000:1 contrast ratio, 200cd/m2 brightness and is capable of displaying 100 percent NTSC color gamut. To manufacture the display Samsung used low-molecular organic EL materials and a low temperature polysilicon TFT control circuit. Samsung didn’t announce when these technologies will come to the market, but said larger size OLED manufacturing should start getting economically feasible after 2009.
