DLP is the abbreviation of English Digital Light Processor, translated as Digital Light Processor. DLP uses DMD (Digital Micromirror Device) as a light valve imaging device. A DLP computer board is composed of an analog-digital decoder, a memory chip, an image processor and several digital signal processors (DSP). All text images are generated through this board to generate a digital signal. After processing, the digital signal is converted To the heart of the DLP system-DMD. After the light beam passes through a high-speed rotating three-color lens, it is projected on the DMD, and then projected on the large screen through an optical lens to complete the image projection. A piece of DMD is formed by a number of tiny square reflecting mirrors (micromirrors for short) arranged closely together in rows and columns on the electronic nodes of a silicon wafer, and each micromirror corresponds to a pixel of the generated image. Therefore, the number of micromirrors of the DMD device determines the physical resolution of a DLP projector. For example, the resolution of a projector is 600X800, which means that the number of micromirrors on the DMD device is 600x800=480,000.
Each micro-mirror in the DMD device corresponds to a memory, which can control the micro-mirror to switch and rotate at two positions of ±10 degrees. Moreover, the area of each pixel on the DMD block is 16 μm×16, and the interval is 1 μm. According to the number of DMD slices used, DLP projectors can be divided into: single-chip microcomputer, two-chip machine, and three-chip machine. The red, green and blue of the DMD digital signal rotate in order, and the small mirror is turned on or off according to the position of the pixel and the number of colors. At this time, DLP can be regarded as a simple light path system consisting of only one light source and a set of projection lenses, and the lens is magnified. The reflected image of the DMD is directly projected on the screen, so that a vivid and bright presentation effect is shown in front of us.
