Sony's organic screens get bigger

CRT killers which don't need backlight

Sony says it has made the world's largest full colour organic Electroluminescence display that it says will eventually replace Cathode Ray Tube displays.

The company is claiming an edge in the race to produce a commercially viable large OEL screen and says it expects it to be in production by 2003.

Development of large-scale OEL displays has been beset with problems. Although highly luminous, and in no need of backlighting, Sony says that conventional driving systems "induce a non uniformity of luminance."

Sony thinks it has found a way round these problems with its Top Emission Adaptive Current (TAC) technology. Sony says this produces high luminance and high resolution

At 13 inches across diagonally, and at a resolution of 800 by 600 pixels, it is probably not a serious threat to your TV set just yet, but give it a couple of years. IDC reckons that the OEL market will be worth a cool $1.7 billion by 2005.

There is no question of Sony stopping producing CRT screens, it said it just expects the OEL market to grow faster.

And manufacturers are expecting plenty of demand for smaller screens. Sanyo, for example, has developed a full colour OEL screen for mobile phones. Other likely initial targets include in-car navigation systems and PDAs. ®
