Principle analysis

Taking the resolution of 1024×768 as an example, there are a total of 1024×768 small mirrors

on a DMD, each mirror represents a pixel, and each small mirror has the ability to independently

control the light on and off. The angle of the small mirror reflecting the light is controlled by the

video signal, the video signal is modulated by the digital optical processor DLP, the video signal

is modulated into a pulse width modulation signal of equal amplitude, and the pulse width size is

used to control the time of the small mirror to open and close the light path, and produce grayscale

images of different brightness on the screen.
