Abstract:
1. An image projection system implemented with a spatial light modulator for modulating an illumination light projected from a light source wherein said spatial light modulator having a plurality of modulating elements wherein each modulating element further comprising: at least two electrically conductive layers functioning as two different electrical wirings and said conductive layers having respectively a first and a second longitudinal directions overlapping and crossing each other; and a fixed electric potential layer electrically connected to a fixed electric potential, wherein the two different conductive layers and the fixed electric potential layer constituting multiple overlapping layers of flat plates each having irregular non-rectangular shapes for complimentarily to one another for covering an entire horizontal surface of the modulating element to totally block the illumination light emitted from the light source to enter into areas below a modulating surface of each of the modulating elements.
