Title: MULTI-SCREEN PROJECTION DEVICE AND METHOD
Abstract:
Disclosed are a multi-screen projection device and method. The multi-screen projection device disclosed in the present invention comprises: a signal processing system, a lens assembly, a number N of digital micromirror devices (DMD), and a DMD driver circuit; N is a positive integer greater than or equal to 2; said number N of DMDs are arranged, not overlapping one another, within the field of view of said lens assembly; said signal processing system is used for converting a to-be-projected image corresponding to the DMD to obtain a DMD drive signal; the DMD driver circuit is used for driving, according to the received DMD drive signal, the corresponding DMD to project. The projections of different DMDs are imaged to different regions on a screen by means of the lens assembly, such that the present invention enables multi-screen projection.
