ABSTRACT:
A video display system having an electrically insulative substrate with a top surface, a bottom surface, and an M.times.N array of holes between the top and bottom surfaces. The M.times.N array of holes corresponds to an M.times.N array of pixels. The system further includes piezoelectric members, each piezoelectric member disposed on the top surface adjacent to each of the holes. Each of the piezoelectric members has two metallized faces and a mirror mounted to the member. An integrated circuit electronic switch matrix is mounted to the bottom surface of the substrate. One of the metallized faces is electrically connected through the holes to the piezoelectric members. The other metallized face is electrically connected to ground. The switch matrix develops electrical signals, with each signal corresponding to an intensity of one of the pixels. The electrical signals are applied to each of the piezoelectric members, each of the piezoelectric members in response thereto changing an orientation of the mirror mounted thereto. Each of the mirrors therefore effects modulation of light intensity reflected from the mirror, and the modulated light intensity from each of the mirrors corresponds to one of the pixels.
