Samsung Creates First LCD with DisplayPort Video Interface

Samsung Electronics announced 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.

The DisplayPort interface technology supports both internal (e.g. for notebook PCs) and external (box-to-box) connector links between PCs and monitors. DisplayPort has a scalable AUX channel for two-way communications, embedded clocking for higher speed, fewer wires, reduced electromagnetic emissions, and a micro-packet architecture for flexible design configurations. Its transmission range is wider than that of other interface standards and can be easily expanded. Besides Samsung, Display Port also is supported through VESA by many PC integrators, graphics chip makers, timing controller silicon makers, and the world's leading producers of digital connection devices.

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 color 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 Genesis Microchip (Santa Clara, California), Samsung developed its 30" 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 color depth or 1.07 billion colors, a feat that would normally require at least three DVI or four LVDS interface chips.

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

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