Abstract
A system for detecting errors in a source driver for an electronic display includes an upstream logic device, a comparator, and a source driver. The source driver has a number of driven channels which transmit active signals for generating an image on the electronic display and one or more dummy channels which transmit dummy signals to the comparator. The comparator receives and compares signals from at least some of the driven channels with the dummy channels and generates an alert for transmission to the upstream logic device if a mismatch is detected.
