Sony’s shift to large 4K TVs follows consumer demand
Publication Date : 28-05-2014
Sony Corp. will withdraw from the development of organic electroluminescence displays for home use and shift to the development of liquid crystal display TVs, according to company President Kazuo Hirai.
However, Hirai said in an interview Monday that Sony would continue developing OEL displays for industrial use.
“Taking into account consumer satisfaction, I think they will choose LCD TVs,” Hirai said.
OEL has been considered a pro-mising next-generation TV technology, and panels using the technology are believed to have clearer images than LCDs. OEL works through the application of voltage to organic materials in each pixel to emit light.
Sony began development of OEL displays in 1994 and sold the world’s first OEL TV with an 11-inch model in 2007.
But the company struggled to mass-produce OEL displays and make larger OEL TV screens. In 2012, Sony launched joint development of large-scale OEL TVs with Panasonic Corp., but they failed to find a method to mass-produce them. Cooperation between the two companies ended last year.
Meanwhile, LCD TVs have been produced in larger sizes. Since 2012, the so-called 4K ultra-high-definition TVs, which have four times more pixels than full high-definition TVs, have been on the market.
“LCD is available for 4K TVs, and can provide beautiful images at reasonable prices to consumers,” Hirai said, adding that the company intends to concentrate on 4K TVs made with LCD.
Sony has sold OEL TVs for professional use, including film editing and medicine. Hirai said the company hoped to continue selling such OEL displays.
