Abstract
A liquid crystal display (LCD) device includes a LCD panel and a source driver. The LCD panel includes pixel data inputs and a failure sensing circuit. The pixel data inputs are coupled to columns of pixel elements. The failure sensing circuit provides a failure indication on an output of the LCD panel. In a test mode, the source driver drives a first voltage onto all of the first pixel data inputs. The failure indication includes the first voltage when the LCD panel has no failures on any of the first pixel elements, and the failure indication includes any other second voltage when the LCD panel has at least one failing pixel element.
