Abstract
A digital lighting process (DLP) projection device is provided. The DLP projection device includes a laser, a digital micromirror device (DMD), a projection lens, and a lens array. The laser emits laser light. The DMD receives the laser light emitted from the laser. The DMD includes a plurality of micromirrors arranged in an array, each of which reflects the laser light. The projection lens receives the laser light reflected from the micromirror, and projects the received laser light. The lens array is arranged between the laser and the DMD, and makes the laser light emitted from the laser uniform.
