Sony successfully developed ultra-thin screens that can bend

In the race to produce ultra-thin screens for TVs, mobile phones and other devices, Sony probably developed a product that beat all other products - it's a thin screen. like a razor can bend like paper while showing a colorful video footage.

Although flat-panel TVs are getting thinner and thinner, a display that is thin and bendable in people's hands marks a breakthrough. Sony said it decided to choose commercial products using this technology.

'In the future, this screen can roll around a lamp post or a person's wrist, can even be worn like clothes,' said Sony spokesman Chisato Kitsukawa. 'Perhaps it can be displayed as a wallpaper.'

Tatsuo Moru, professor of computer science and engineering at Nagoya University, said the race still exists, including making this screen bigger, ensuring durability and lowering costs. But he said it was extremely difficult to mimic the flexibility of the screen with liquid crystal displays and plasma screens - two major display technologies currently on the market.

'To create a flexible screen that image quality is groundbreaking,' said Mori. ' You can drop it, and it won't break because it's as thin as paper.'

This new screen combines two technologies: TFT technology (thin film transistor), the technology required to create flexible displays, and Sony's OLED organic electroluminescent display technology.

Other companies, including LG Group. Philips LCD and Seiko Epson Corporation, are also working on another type of ' electronic paper ' technology, but Sony said, OLED technology displays better color images and is more suitable for video.

Sony president Ryoji Chubachi said the film-like screen is the main technology his company is working on to boost its position as a major manufacturer of technology.

At a press conference more than a year ago, Chubachi boasted that Sony was working on a production technology that produced screens that were so thin that it could be rolled up like paper. He predicted that the world would have to stand up and pay attention to it.

Some analysts say Sony, which has created the Walkman portable player and PlayStation 3 video game player, has slipped behind other competitors in flat-screen technology, including corporations. South Korea's Samsung Electronics and Japan's Sharp Group.

But Sony marked a turning point under the management of Mr. Chubachi and chief executive Howard Stringer, the first foreigner to lead Sony, by reducing jobs, closing companies that did not make a profit. and promote its flat-panel TV products.
