Epson Announces Projector Light Control System with Major Performance Gains Jointly-Developed with Philips
Contrast improved by approx. 500% and energy consumption reduced up to half
TOKYO, Japan, Seiko Epson Corporation (“Epson”, TSE: 6724) today announced it has collaborated with Royal Philips Electronics, Inc. (“Philips”, NYSE: PHG, AEX: PHI) on core modules for projectors to develop a new light control system for 3LCD projectors. The new system uses Epson’s high-temperature polysilicon (“HTPS”) TFT LCD drive technology and Philips’ lamp technology, and achieves improvements in both projector image contrast and energy consumption. The two companies are now shipping samples of the new system to projector manufacturers.
In recent times, projectors for both business and home have faced increasing demands for improvements in core projector capabilities such as image quality, contrast, brightness, and low energy consumption and the new system was designed to meet these requirements.
The new light control system comprises a projector lamp and lamp drive circuits and is compatible with Philips’ ImageCare*1 lamp control technology and Epson’s HTPS panel light control technology, which makes use of Epson’s long experience of developing HTPS panel driving technologies, achieving high image quality and superb color reproduction by automatically adjusting in real time the white balance deviations that occur due to changes in lamp power. 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 have resulted 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*2.
“We have been able to realize the new system by combining the HTPS technology we have developed over the years and Philips’ excellent lamp technology,” said Nobuyuki Shimotome, chief operating officer of Epson’s TFT Operations Division. “I am convinced this system meets projector market demands for high quality and environmentally-conscious products. Epson’s TFT business continues to contribute to the development of the projector market both through innovations in HTPS technology and by optimizing the advantages of optical systems.”
“Based upon a deep understanding of customers and end-users, Philips believes that innovations in UHP*3 lamp systems can meet market needs such as long lamp life and energy saving,” said Peter van Berkel, chief executive officer of Philips Digital Projection Lighting. “ImageCare technology is based on the successful and much admired UHP system, and meets urgent and basic requirements that exist in the mainstream projector market. This is a superb example of how we have developed meaningful solutions for end-users by combining Epson’s state-of-the-art HTPS panel systems with our advanced technologies.”
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.
With over 20 years of experience in meeting projector market demands for superior image quality and high contrast, Epson has leading share in the market for core projector devices*4. Epson will continue to develop HTPS panels as it seeks to provide improved added value solutions for projectors.
