Parade Announces 4K eDP Tcon for Monitor and All-in-One Panels

First 4K eDP timing controller for monitor panels that utilizes SST (Single Stream Transport)

San Jose, Calif.— 22 October 2014 —Parade Technologies, Ltd. (Taiwan OTC: 4966.TWO), a leading video display and interface IC supplier, today announced a new eDP Tcon device for 4K LCD panels designed for computer monitor and all-in-one applications. This new device, the DP667, is the first Tcon (timing controller) for such applications that supports the use of the standard DisplayPort SST protocol for 4K resolution.

The DP667 supports resolutions up to 3840 x 2160 (UHD) using standard 24-bit or extended 30-bit color, at refresh rates up to 60 frames per second. This performance is supported through a single eDP (Embedded DisplayPort) interface operating at the HBR2 link rate (5.4 Gbit/sec) utilizing all four Main Link lanes. Parade developed the DP667 specifically to support 4K using the standard DisplayPort SST (Single Stream Transport) protocol, reducing the system complexity associated with tiled array approaches that require the more complex DisplayPort MST (Multi Stream Transport) protocol.

“Traditionally only used between a GPU and embedded display, eDP is now making inroads as the panel interface within a computer monitor,” said Jimmy Chiu, Executive VP of Marketing at Parade Technologies. “As monitors move towards higher resolution such as 4K and beyond, the pin and wire count to support the existing LVDS interface, or even MIPI, is simply not practical. And enabling the DP667 with an SST interface means it can be supported by various monitor controller devices, in addition to a direct GPU interface with an AIO device. The use of SST ensures improved compatibility and interoperability, and can also reduce display enabling latency.”

The DP667 is compliant to eDP v1.3 and includes backlight control capability through the eDP AUX Channel. The output of the DP667, which interconnects to the LCD column drivers, supports various point-to-point COF/COG interface types including Parade’s SIPI™ interface standard. The DP667 supports eDP power management features including variable frame rate control protocols compatible with all popular GPUs, and supports the DisplayPort Adaptive Sync feature. Device configuration capability includes programmable Tcon control signal generation, row / column driver I/Os, and a programmable Gamma look-up table.

Parade is the leading supplier of eDP Tcon devices worldwide, working in partnership with leading LCD manufacturers and system OEMs.


The DP667 is in production now, and is available in both a DRQFN and WFBGA package.
