Abstract
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.
