Parade Announces New Tcons Compliant To New VESA eDP 1.4b Standard
Posted October 27th, 2015
First Embedded DisplayPort panel timing controllers designed to eDP 1.4b enable reduced power and BOM cost, and increased system compatibility
San Jose, Calif.— 27 October 2015 —Parade Technologies, Ltd. (Taiwan OTC: 4966.TWO), a leading video display and interface IC supplier, today announced two new eDP Tcon devices that comply to the newly released eDP 1.4b Standard. Systems utilizing eDP version 1.4b will begin production in 2016, and Parade’s new devices target the main-stream, high-volume system market. The DP691 supports display resolutions up to 2560×1700, and the DP693 supports up to 1920×1200. Both devices support up to 24-bit RGB color format.
Since the introduction of eDP (Embedded DisplayPort) over five years ago, Parade has remained the leading supplier of eDP Tcons (display timing controllers) and continues to make major contributions to the Standard through VESA (the Video Electronics Standards Association). eDP has become the standard video interface for internal display panels in mobile personal computers, All-in-One system, high-end tablets, and increasingly within desktop monitors. The DP691 and DP693 support the latest iteration of Panel Self Refresh (PSR), defined as PSR2 in eDP 1.4, that includes selective update capability of the display’s local frame buffer. Refinements included in the new eDP 1.4b release, many contributed by Parade, include the ability to implement PSR2 without added BOM cost to the display panel. The new DP691 and DP693 devices also support the use of VESA DSC (Display Stream Compression), as per the new eDP 1.4b spec implementation, to enable further reduction in BOM cost and power. The devices offer backward compatibility with eDP 1.3 and earlier Source devices.
“Within the personal computer industry, the eDP 1.4b release is considered to be the final production version of the eDP 1.4 Standard,” said Jimmy Chiu, Executive VP of Marketing at Parade Technologies. “eDP 1.4 represents a major improvement in power reduction, display performance, and general system optimization. For the eDP ecosystem, Parade continues to contribute substantially as a display-side integrator, working actively with the major chip set, panel, and system OEMs.”
The DP691 and DP693 are fully programmable devices enabling compatibility with various panel configurations. The panel-side interface to the column drivers supports various point-to-point COF/COG interface types including Parade’s SIPI™ interface standard. Special media playback modes are supported and complemented by accurate color capability through a programmable color engine and gamma correction, in addition to Parade’s exclusive Smart-Backlight™ feature for additional color and power optimization. The DisplayPort Adaptive Sync feature is supported along with other eDP power management features including other variable frame rate control protocols.
Packaging and Availability
The DP691 is packaged in a 76 pin, 5x12mm QFN package. The DP693 is packaged in a 66 pin, 5x10mm QFN package. Samples are available now.
