Abstract

The invention provides a micro-mirror display which comprises a substrate, a first reflector, a second reflector and a third reflector, wherein the first reflector can rotate along a first axis and is used for reflecting first spectral band light in incident light by diffraction or interference between two conductive reflecting layers of the first reflector; the second reflector can rotate along a second axis and is used for reflecting second spectral band light in the incident light by diffraction or interference between the two conductive reflecting layers of the second reflector; the third reflector can rotate along a third axis and is used for reflecting third spectral band light in the incident light by diffraction or interference between the two conductive reflecting layers of the third reflector; the first reflector, the second reflector and the third reflector are separately arranged in a array mode, and the first axis, the second axis and the third axis are parallel with the substrate. The micro-mirror display provided by the invention can display with various colors, has simple optical path design, and does not need to carry out complex control for light beam with different colors.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to a micromirror display (MicroMirror Display). Background technique [0002] The Micromirror Device (Digital Mirror Device, MMD for short) used in projection equipment was originally proposed by Hornbeck in the US patent document US5600383. The DMD includes deflectable isomorphic mirrors (isomorphic mirrors) array. All mirrors are identical in that they reflect and modulate incoming light (eg, visible light). Accordingly, if different spectral bands of light need to be processed, for example, different colors need to be produced, a color image display is required. A color image display can be obtained through sequential processing by a single DMD. It is also possible to obtain a color image display through DMDs corresponding to each wavelength or color, that is, to combine three kinds of DMDs with a prism, and to process the light of each main color as...
