Digital Light Processing (DLP) is a display technology that utilizes a digital micromirror device (DMD) to project images, often found in projectors and 3D printers. It works by reflecting light off microscopic mirrors, with each mirror representing a pixel, to create a sharper, brighter image compared to other projection technologies. DLP is also a 3D printing method that uses a digital projector to cure a liquid photopolymer resin layer by layer, resulting in highly accurate and detailed 3D objects.
