ABSTRACT:
A membrane light modulator contains a substrate, the substrate contains a first face and a second face. A plurality of first electrodes is arranged in a matrix of p rows and q columns. Each first electrode is affixed to the substrate by a suitable means. Each column of first electrodes is overlapped by a respective deformable reflective column conductor. Each column conductor is affixed to the first face by a suitable means. Each first electrode is electrically connected to a respective third switch terminal of a respective switching element. Each switching element is affixed to the second face by a suitable means. Each first electrode overlapps the respective switching element. A suitable potential control means is provided to control the potential difference between each first electrode and the respective column conductor in accordance with a input signal. Affixing switching elements to the second face and column conductors to the first face provides fabrication flexibility to enhance commercial viability. A no crossover switch matrix addressing configuration further enhances reliability and commercial viability of the modulator.
