DP677 / DP678 — Very Low Power 1 Lane eDP 1.2 Tcons

Embedded DisplayPort v1.2 Timing Controllers, Very Low Power

DP677 and DP678 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 1680×1050 with 18 bit color depth, or up to 1366×768 with 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 DP677 and DP678.
