Seiko Epson Corporation has developed what it’s claiming is the world’s first 40-inch full-colour display based on organic light-emitting diode (OLED) technology.
Self-luminescent OLED displays, which offer outstanding viewing characteristics, including high contrast, wide viewing angle, and fast response times, are widely seen as the leading candidate for the next generation of thin, lightweight displays.
But one of the major obstacles to their realisation, however, has been the perceived difficulty of forming organic layers on large-sized TFT (thin film transistor) substrates.
To solve that issue, Epson developed an original inkjet process for depositing organic layers on large-size TFT substrates. And it was using this adapted inkjet technology to form organic layers on large-size substrates in a simple process, that Epson was able to build the OLED display prototype.
The company is gearing up towards full OLED production by 2007.
