Sony Demonstrates 13-Inch, Full-Color OEL Display Prototype

Sony Corp. disclosed a prototype of a 13-inch, full-color organic electroluminescent (OEL) display at CEATEC JAPAN 2001, an annual trade show of electronic and telecommunications products that opened on Oct. 2.

The display is one of the largest of its kind for an active-matrix organic electroluminescent displays using low-temperature polysilicon thin-film transistors. Sony plans to commercialize its display by the end of 2003.

An OEL display is a next-generation display that can be thinner and more energy-saving than a liquid-crystal display because its sensors are self-luminous. Sony exhibited a 13inch, or 1.5mm-thick, display with a resolution of 800 x 600 pixels and a 10-in. display with a resolution of 864 x 480 pixels. The luminance of the both models is 300cd per square meter.

The Sony booth attracted the largest number of visitors at the exhibition.

At CEATEC, Pioneer Electronic Corp. and Sanyo Electric Co., Ltd. also exhibited innovative OEL displays.

Pioneer introduced an ultra-thin electroluminescence film display. The display adopts 0.2mm thick, bendable film. Pioneer said it assumes the display will be used for cellular phone handsets and clothes. At its booth, the company exhibited a costume with the display attached to it.

The 3-in. display has a resolution of 160 x 120 pixels. Although only single-color displays in red, blue and green were shown at the booth, a company spokesperson said the maker can also technically produce a full-color model. Pioneer has not announced when it will commercialize the model.

Sanyo Electric showcased a prototype model of a wireless television that uses an OEL display. The 5.5-in., battery-operated TV has a resolution of 320 x 240 pixels. The company separately sells a tuner to receive television waves, via which the TV can receive images wirelessly.

Although Sanyo did not disclose the outer dimensions, it said it hopes to commercialize a 5.5-in. TV, as exhibited at the booth.
