Abstract
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.
