INTERNATIONAL. Samsung Electronics Co, the world’s largest provider of thin-film transistor liquid crystal display (TFT-LCD) panels, announced today that it has developed the world’s first LCD panel using the next-generation video interface 'DisplayPort'. Sanctioned by VESA (the Video Electronics Standards Association), DisplayPort will serve as a replacement for DVI, LVDS and eventually VGA.

For Samsung’s new 30-inch LCD, the DisplayPort interface transmits graphics data at a total data rate of 10.8Gbps.  This speed enables 2560x1600 resolution without any colour smear. By using a transmission speed more than double that of today’s interfaces, Samsung’s new LCD only requires a single DisplayPort interface, instead of the two DVI (Digital Visual Interface) ports now used. 

In a joint undertaking with US firm Genesis Microchip, Samsung developed its 30-inch panel using a new four-lane, 2.7Gbps/lane interface chip. The interface technology processes 2560x1600 pixels of graphics data at up to 10 bits of colour depth or 1.07 billion colours, a feat that would normally require at least three DVI or four LVDS interface chips.

“We are pleased to be the first LCD manufacturer in the world to create a panel with a DisplayPort interface,” said Brian Berkeley, Vice President, Samsung LCD Business, who is leading the company’s DisplayPort development efforts.

“We have received many inquiries from computer integrators interested in DisplayPort-based LCD panels, which prompted an acceleration of our R&D for this first DisplayPort LCD panel.” 

Samsung was the only LCD panel maker participating in the original DisplayPort working (standards) group formed in 2004.

Samsung’s new 30-inch LCD also offers the company’s proprietary Super Patterned Vertical Alignment (S-PVA) liquid crystal technology for 180 degree viewing angle, and 300nits brightness.

Mass production of the 30-inch panel is scheduled to begin in the second quarter of 2008.
