PROBLEM TO BE SOLVED: To generate a high resolution full color with saved power. SOLUTION: Light in the visible spectrum is modulated by using an array of modulation elements (501), and control circuit connected to the array for controlling each of the modulation elements independently, each of the modulation elements has a surface (506) which is caused to exhibit a predetermined impedance characteristic to particular frequencies of light. The amplitude of light delivered by each of the modulation elements is controlled independently by pulse code modulation. Each modulation element has a deformable portion (508) held under tensile stress, and the control circuit controls the deformation of the deformed portion. Each deformable element has a deformation mechanism and an optical portion, the deformation mechanism and the optical portion independently impart to the element respectively a controlled deformation characteristic and a controlled modulation characteristic. The elements are made by forming a sandwich of two layers and a sacrificial layer between them, the sacrificial layer having a thickness related to the final resonator dimension, and using chemical (e.g., water) or a process based on plasma to remove the sacrificial layer.
