Optical system of display

摘要

There is provided an optical system of a display constituted of: a light conducting plate introduced with light; and a panel portion provided to oppose to one plate surface of the light conducting plate; the panel portion including a driving part arranged with actuator parts each corresponding to a plurality of pixels so as to control displacement motions of the actuator parts in the contacting/separating directions to/from the light conducting plate correspondingly to attributions of input image signals, thereby controlling leaked light-beams in predetermined regions of the light conducting plate, to thereby cause the light conducting plate to display an image corresponding to the image.
