ABSTRACT:
A display device includes an illuminating device having an optical waveguide plate for introducing light thereinto, a drive assembly having a planar array of actuators disposed in facing relation to the optical waveguide plate, a displacement transmitter assembly disposed between the optical waveguide plate and the drive assembly, and a light scattering layer disposed on the displacement transmitter assembly. The actuators are selectively displaceable to bring the light scattering layer into and out of contact with the optical waveguide plate, for controlling light that leaks from the optical waveguide plate as emitted light. The display device also includes an optical modulator for modulating the emitted light from the illuminating device to display an image. The illuminating device has a light reflecting layer disposed on at least a portion of the displacement transmitter assembly that confronts the optical waveguide plate.
