Computex show in the latest VESA DisplayPort 1.2 version released details of the new specifications

Order to improve the performance of next-generation display interface standards, Video Electronics Standards Association (VESA) today at the Taipei International Computer Show (Computex 2009) released the latest version of the new DisplayPort 1.2 specification details. The new version 1.2 upgrade will not only greatly enhance the transfer rate, and UC3525AN datasheet and can support four times 4K2K ultra high resolution and UC3525AN price and 3D digital signal transmission. VESA is expected to be completed before the end of this year to develop new specifications, certified in 2011 to see related products listed.

VESA says that at first to replace DVI, VGA and UC3525AN suppliers and LVDS display interface such as PC digital interface and the development of DisplayPort, after PC market applications in the growth, the future will be more into the currently dominant HDMI flat panel display and DVD player and other consumer appliances markets. HDMI 1.3 support

10.2Gbps than the maximum transfer rate, the current version of bandwidth to support DisplayPort 1.1a to 10.8Gbps, and other peripheral devices and have a higher compatibility; In addition, the latest version 1.2 transfer rate will also be increased to 5.4Gbps per channel bandwidth, the maximum support 4-channel 21.6Gbps rate.

DisplayPort 1.2 version also supports 3D display, and four times the 3,840 × 2,160 high-resolution video signal. Through a daisy chain (daisy-chain) cable configuration, using a single controller can support multiple simultaneous display of data streams between devices; higher auxiliary (AUX) channel bandwidth speeds up to 480Mbit / s, fully supports USB 2.0 data transfer and protocol.

For audio and video signals in the content encryption protection, HDMI and HDCP are used DispalyPort both content protection mechanism; However, the biggest difference between the two is that the right to payment, certification. As a fully open and extensible standard, DisplayPort does not need to pay licensing fees required for HDMI interface, and, therefore, well received by the controller IC and other vendors.

In addition, the new standard will also provide a new mini DisplayPort 1.2 connector. VESA said Apple (Apple) of the MacBook to use this mini DP connector. In addition, DisplayPort has received Intel (Intel), AMD, Dell (Dell), Hewlett-Packard (HP), IDT, LG, Philips (Philips) and Samsung (Samsung) and other manufacturers for their support.

Certification in testing, testing lab Allion (Allion) Standard Test Engineering Services Division, said director Li Changzong, VESA DisplayPort also set out the consistency of the test (compliance test) standards, in order to achieve the best DP devices best interoperability. In addition to the jitter tolerance, eye diagram and the slope compensation and other physical layer testing and link layer tests EDID outside the 1.1a version of the future after the DP products will also add compatibility testing voice signals.
