Abstract
A display device using a micro light modulator that is capable of applying to various display apparatus. The display device has a plurality of fixed members installed parallel to each other over a substrate, the member being apart from each other; and a plurality of moveable members being driven with the fixed members by a statically electric force to switch a path of lights incident from the substrate.
Claims36
A display device using a micro light modulator, comprising:
- a plurality of fixed members installed parallel to each other over a substrate, the fixed members being apart from each other;
- a plurality of moveable members being driven with the fixed members by a statically electric force to switch a path of lights incident from the substrate;
- a back light unit installed opposite to an incident plane of the substrate to irradiate lights at a predetermined angle for the incident plane of the substrate;
- and
- a diffusing sheet, opposite to an output plane of the substrate, for diffusing the lights being incident thereto.
