UK display firm teams up with HP to address consumer market

Cambridge Display Technology (CDT) and Hewlett-Packard have formed a joint programme to develop light-emitting polymers for consumer applications. The two companies have signed a cross-license agreement that gives each company access to the other’s technology.
Joint research is intended to combine HP’s technology expertise in silicon and optoelectronics with the UK firm’s light-emitting-polymer technology to make a high-density display with more vibrant colors, wider viewing angles and lower manufacturing costs than today’s conventional liquid crystal displays, both firms said in a statement.
“Our joint development program with HP is another sign that light-emitting- polymer displays will have a substantial impact on the display market. HP is a well-respected technology company that is active in many of the markets that LEP will impact,” said Danny Chapchal, chief executive officer of CDT.
Light-emitting polymers are organic polymer materials that actually emit light when a voltage is applied to electrodes on both sides of the material. In contrast, liquid crystals do not emit light and require a backlight to be seen in the dark.
“We think that light-emitting polymers could eventually result in applications in a wide variety of consumer products, including printers, cellular phones and personal digital assistants,” said Gary Baldwin, director of the Solid-State Technology Laboratory at HP Laboratories in Palo Alto, Calif.
