LG Electronics plans to commercialize a 20-inch OLED TV model this year, with 30-inch and 40-inch models to folow in 2011 and 2012.
Won Kim, LG's vide president, expects that the price of the OLED TVs will fall by 2012, making a 40-inch OLED TV model more affordable for consumers.
The company has been already offering a a 15-inch AM-OLED TV priced at $2500.
The high price of the active-matrix organic light-emitting diodes has kept it from becoming a mass-produced technology in the TV panels. Sony launched the world's first OLED TV in late 2007 but has not followed with new models yet.
Average pricing for an 11-inch AM-OLED television is presently about $2,500, compared to $704 for a 42- to 44-inch LCD television. Due to manufacturing challenges and limited production, OLED-TVs are expectd to remain small in size and high in price in the coming years, consigning them to small niche of the global television market.
Currently there is a small investment in fabs capable of producing larger AM-OLED panels that can compete directly with the most popular LCD-TV sizes. Because of this, it is unknown whether high-volume manufacturing of large-sized AM-OLED panels can generate yields that are competitive with other display technologies. OLED panels are based on a current-driven backplane technology that offers poor stability and a lack of uniformity.
Lifetime issues are also a concern, with large-sized AM-OLED TV sets operational life constrained by the OLED material performance and differential aging of the various materials in the display.
AM-OLEDs also suffer from "image sticking," a phenomenon that leaves an artifact on a screen after a static image is displayed too long.
On the other hand, OLEDs are offering higher brigthness and sharper colors compared to LCDs, while they remain more power-efficient.
