DP676 / 679 — Very Low Power 2 Lane eDP 1.2 Tcons

Embedded DisplayPort v1.2 Timing Controllers, Very Low Power

DP676 and DP679 were developed with emphasis on very low power consumption, while supporting all of the necessary features of a timing controller for mobile and AIO PC applications. The devices support eDP 1.2 allowing backlight and other panel functions to be controlled through the eDP AUX Channel. They support a display resolution up to 1920×1200 with up to 24 bit color depth. Back-side interface support to the LCD Source Drivers include mini-LVDS, Parade’s own SIPI® (Scalable Intra Panel Interface) CoG interface, and the support of other common CoG interface types that differentiate the DP676 and DP679.
