RiTdisplay selects AIXTRON’s OVPD technology for OLED Display Production

Aachen / Hsinchu, Taiwan R.O.C., May 7 2003- AIXTRON is delighted to announce the sale and joint testing of AIXTRON’s 2 generation Organic Vapour Phase Deposition (OVPD) equipment with RiTdisplay Corporation, one of the world’s leading OLED manufacturers, situated in Hsinchu, Taiwan. RiTdisplay has successfully developed OLED main and sub-displays for mobile phones, instrument front panel displays, E-books, games, and personal digital assistants (PDA). AIXTRON and RiTdisplay will enter into a joint -testing agreement with the aim of qualifying the OVPD 2 generation tool for the mass production of RiTdisplay OLED displays. AIXTRON’s development of this highly sophisticated OVPD tool, suitable for 2 generation mother glass size (~370 x 470 mm) OVPD displays, began in 2002 as part of the OVPD joint development program with the Universal Display Corporation (UDC). The delivery of the OVPD system to RiTdisplay is planned before the end of this year.

Yih Chang, General Manager at RiTdisplay describes: “We hope that AIXTRON’s OVPD equipment technology will enable us to strengthen our market position. The potential of quality and cost saving performance of AIXTRON’s equipment is attractive to us. We wish the -testing will enable us to make a smooth introduction into production. We look forward to a successful co-operation with AIXTRON whose equipment expertise in this field is complementing our thorough knowledge of OLED mass production in an excellent way.“

Tim McEntee, Executive Vice President of AIXTRON’s Semiconductor Equipment Unit states: ”RiTdisplay’s decision to choose AIXTRON’s OVPD equipment technology is proving us right in advancing the production technology of the emerging OLED display business. We are pleased that a renowned company like RiTdisplay opts for AIXTRON’s OVPD equipment and have no doubt that our product will exceed their expectations. We believe that AIXTRON’s OVPD tool will be the future choice for OLED display production.”

The OVPD module is equipped with a separate shadow mask storage module to allow a fast access and transfer of shadow masks needed for display production. An In-situ Mask Alignment system inside the OVPD deposition chamber allows the full deposition and patterning of all organic layers and pixels required for full-color display production. The main unique features of this technology are: High organic material deposition efficiency, high thickness and doping uniformities and the capability to deposit all organic layers to form all required colors in one chamber thus giving advantage in production in terms of cost and quality. As reported in September 2000 AIXTRON secured the exclusive license from UDC for OVPD technology and stepped into a development agreement for OVPD equipment with the New Jersey based company. Within the scope of work a 1 demonstration pre-production OVPD tool was delivered to UDC in 2002. After the initial ‘proof of concept’ of AIXTRON’s OVPD equipment technology last year based on the beneficial and complementing collaboration of the two companies, AIXTRON and UDC continued to develop and to scale this technology towards today’s market needs.
