 DLP projector DLP Digital Light Processor English acronym translated digital light processor. DLP with DMD (Digital Micromirror Device) is used as a digital micromirror light valve imaging device. A DLP computer board from analog to digital decoder, memory chips, an image processor and a few digital signal processor (DSP), all of the text image is through this board to produce a digital signal light projectors offer, treated , a digital signal to the DLP system heart --DMD. After the light beam passes through the tri-color and a high-speed rotation of the lens, is projected on the DMD, and then complete the image projected on a large screen projected by an optical lens. A DMD is composed of many tiny square lens reflex (the microscope), closely arranged in rows and columns with nodes attached to the electronic formed of a silicon wafer, each micromirror corresponds to a pixel for generating an image. Therefore, the number of DMD micromirror device determines a physical resolution DLP projector, such as a projector has a resolution of 600X800, referring to the number on the DMD micromirror devices have 600x800 = 480000 个. Vertical scanning electron beam in the horizontal scanning frequency, while Nanshan projectors offer, and from the downward movement, this process is called vertical scan. Forming an image scanned once every Baoan projector purchase, the number of scans per second is called the vertical scanning frequency, also called vertical scan frequency refresh rate, which represents the number of times per second refresh this image. Vertical scanning frequency is generally not less than 50Hz, otherwise the image will light flashes. The total bandwidth of the video projector video channel bandwidth, which is defined in the video signal amplitude decreased to 0.707 times the upper limit of the corresponding signal frequency. 0.707 times the corresponding increment is -3db, it is also called the -3db bandwidth.
