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.

System and method for detecting errors in a source driver

An electrical assembly for detecting failures in an LCD source driver includes a plurality of active channels on the source driver which communicate electronically with an LCD. A split active channel on the source driver is provided with an original signal and splits the original signal into an active split channel and a dummy split channel. The active split channel is sent to the LCD. A microprocessor receives the dummy split channel and compares the received dummy split channel signal to the original signal.

LCD source driver feedback system and method

An electrical assembly and method for detecting failures in an LCD source driver is disclosed herein. A plurality of active channels are placed on the source driver which communicate electronically with an LCD. At least one dummy channel may be placed on the source driver which is driven with an original signal. A microprocessor may then receive the dummy channel and compare the received dummy channel signal to the original signal. An error message may be transmitted when the received dummy channel signal does not match the original signal. Alternatively, the source driver may be provided with a split active channel which is provided with an original signal that is split into an active split channel and a dummy split channel. While the active split channel is sent to the LCD, the dummy split channel is sent to the microprocessor for comparison with the original signal.
