LCD projector: It is a high-tech product brought by the development of LCD technology, lighting technology and integrated circuit.
The projector uses the photoelectric effect of liquid crystal, that is, the arrangement of liquid crystal molecules changes under the action of electric field, which affects the transmittance or reflectivity of its liquid crystal unit, thus affecting its optical characteristics, generating signals with different grayscales and colors and displaying output images.
LCD projectors are divided into: 1: LCD flat panel projectors.
2. LCD light valve projector
Technical characteristics of DLP projector:
Digital optical processor
Digital optical path processor-a projector developed by DLP patented technology developed by Texas Instruments.
DMD digital micromirror is mainly used as imaging equipment. It is very different from LCD projector, and its imaging is realized by thousands of tiny lenses reflecting light.
