Abstract
An example embodiment includes a continuity testing method of a pixel in a liquid crystal on silicon integrated circuit. The method includes writing a first voltage to a pixel. The pixel is isolated and a wire that is selectively coupled to the pixel is discharged. The method also includes enabling a sensing amplifier configured to sense voltage on the wire. The pixel is electrically coupled to the wire and a resultant voltage on the wire is sensed.
