Claim:
1. A system for patterning on a substrate comprising a light source, a light patterning device, and a controller coupled to a computer to control said light patterning device, wherein said light patterning device comprises a transparent glass substrate as a negative electrode facing said light source, a transparent glass substrate as positive electrode, and an array of liquid crystals, each of said liquid crystals having an on and off status digitally controlled by said computer, wherein when a liquid crystal's status is on, light from said light source passes through said liquid crystal, and when said liquid crystal's status is off, light from said light source is blocked from passing through said liquid crystal, and wherein said array of liquid crystals' configuration is determined by a digital file for one or more particular patterns such that light beam after passing through said light patterning device represents said one or more particular patterns.
