Embodiment Construction

[0012] see figure 2 , is a schematic plan view of the micromirror projector of the present invention. The micromirror projector 2 of the present invention includes a light source 100 , a converging lens 200 , a color wheel 300 , a trimming lens 400 , a micromirror chip 500 , a diffraction component 600 and a projection component 700 . The color wheel 300 includes three color regions of red, green and blue, and can rotate at high speed. The micromirror chip 500 includes a micromirror component (not shown) with a plurality of micromirrors and a processor (not shown). The plurality of micromirrors receive signals from the processor to perform rapid switching actions.

[0013] The light emitted by the light source 100 is converged to the color wheel 300 through the converging lens 200, and the high-speed rotation of the color wheel makes the passing light turn into three monochromatic colors of red, green and blue in a very short time. The light is incident on the micromirror p...

Abstract

The invention relates to a micro-lens projector that includes a light source, a concourse component, a color wheel, a finishing component, a micro-lens chip and a projecting component. The micro-lens projector also contains a diffraction component that is located between the micro-lens chip and the projecting component to make the light more precision.

Description

【Technical field】 [0001] The invention relates to a micromirror projector. 【Background technique】 [0002] Micromirror projector is a digital projection display system developed by Texas Instruments, also known as DLP (Digital Light Processing) technology. It uses the aluminum mirror surface on the digital micromirror device DMD (Digital Micromirror Device) to reflect light, and controls whether the light enters the display optical path by controlling the angle of the mirror surface. The digital micromirror component is provided with a plurality of mirror support posts (Mirror Support Post), torsion hinges (Torsion Hinge) and yoke (Yoke), etc. on the semiconductor substrate. The torsion hinges are connected to the micromirror posts and operated by electrical signals. Twisting the hinge will drive the micromirror to deflect through the micromirror pillar. One micromirror assembly that Texas Instruments has built includes more than one million micromirrors, each 16 microns o...
