DisplayPort 1.1; Single Connector Replace All
News Posted 05/04/07
|The Video Electronics Standards Association (VESA) announced today that its membership has approved version 1.1 of the DisplayPortâ¢ interface standard for use in new designs of flat panel displays, projectors, PCs and CE devices.
DisplayPort 1.1 gives manufacturers of LCD panels, monitors, graphics cards, PC chipsets, projectors, peripherals, components, and consumer electronics a next generation digital interface that is designed to replace LVDS, DVI, and eventually VGA. DisplayPort provides the ability to connect to both internal and external displays with a common digital interface. This common interface capability means that DisplayPort can carry pixels directly from any display source to any LCD panel, simplifying the design complexity that is present today. As presented at CES 2007, a DisplayPort Interoperability Guideline is nearing completion that recommends best practices for providing DVI and HDMI connectivity via the DisplayPort connector and simple cable adapters.
DisplayPort 1.1 adds support for High Bandwidth Digital Content Protection (HDCP) version 1.3. HDCP support enables viewing of protected content from Blu-ray and HD-DVD optical media over DisplayPort 1.1 connections.
DisplayPort 1.1 provides for low voltage and low power operation, and enables improved interoperability and reduced EMI through its unique embedded clock architecture. Significant advantages over DVI and VGA include a small USB-sized connector with available latching, two-way display connectivity, optional audio support, higher performance than dual link DVI at 10.8 Gigabits per second, and a unique micro-packet architecture that enables new display features.
âThe benefits of version 1.1 are significant, and will encourage adoption of DisplayPort in new generations of computers and consumer electronics equipment,â said Bill Lempesis, VESA executive director. âOur task groups and committees within VESA worked very hard to ensure that DisplayPort 1.1 satisfies the important objectives it is designed for, and as a result, this new version has widespread support among all the leading computer and consumer electronics suppliers.â
Available throughout the industry as a free to use, open and extensible standard, DisplayPort is expected to accelerate adoption of secure digital outputs on PCs, enable higher levels of display performance, and introduce high volume digital displays that are simpler, thinner, and easier to use than VGA.
