DLP is an abbreviation for "Digital Light Processing", which means that make a digital processing for the video signal and then project it. DLP is the technology that based on DMD (Digital Micro mirror Device) technology produced by TI (Texas Instruments) to complete the visual display of digital information. Specifically, the DLP projection technology take DMD as the primary key of the optical processing element to implement the digital processing. And Toumei C800 smart projector utilize the DLP technology to make the projection more vivid.
