Epson, Philips Co-Develop Projector Light Control System.

Seiko Epson Corporation collaborates with Royal Philips Electronics on core modules for projectors to develop a new light control system for 3LCD projectors. The two companies are now shipping samples to projector makers.


The new system uses Epson's high-temperature polysilicon (HTPS) TFT LCD drive technology and Philips’s ImageCare lamp control technology. Based on the results of image analysis performed by Epson's panel drive circuits, lamp drive circuits compatible with Philips' ImageCare continually adjust the lamp brightness according to the image being projected. The combination of the two companies' technologies, say the makers, results in a light control system that improves contrast by approximately 500% and energy consumption by up to half compared to conventional systems used in 3LCD projectors.

Both Epson and Philips plan to sell the core modules they have developed. The new system is compatible with all Epson HTPS panels currently being supplied to projector manufacturers.
