LG said on January 6 that this year it will launch a 55-inch flat-panel TV with a weight of only 7.5 kilograms and a thickness of less than 0.2 inches. Samsung also expects to release similar products at the CES show in early January. A city-adjusting agency estimates that the listed unit price is expected to be around US$8,000. Since then, the sales volume has increased and is expected to drop to US$4,000 by the end of next year.
This year, Samsung and LG are focusing on the new ultra-thin flat-panel TVs, mainly due to technological breakthroughs in organic light-emitting diodes (OLEDs). At present, flat-panel TVs on the market still use LCD TVs as the bulk, followed by plasma TVs. The advantage of OLED display technology lies in the self-illumination of the panel, so that the TV screen can be made lighter and thinner without the need of a backlight. However, due to various technical problems, the OLED is mostly applied to a small-sized screen such as a mobile phone or a car stereo. In the past, major manufacturers have tried to produce large-size OLED TVs, but they have never found a cost-effective production technology. Until LG bought Eastman Kodak's OLED technology patent in 2009, it successfully broke through the technical problems.
LG expects to launch 55-inch OLED TVs this year and reach maximum capacity next year, while OLED panels will be supplied by LG Display of the same group. Samsung also produces 55-inch OLED TVs through improved technology, while panels are supplied by Samsung Action Display.
