7.2 Typical Application

The DLP991UUV DMD is a 4096 × 2176 resolution DLP digital micromirror device. When combined with the TI DLPC964 Industrial Controller and other electrical, optical, and mechanical components, the DLP991UUV DMD provides a superior system for industrial direct imaging and 3D Printer applications. A typical single-chip system application using the DLP991UUV DMD is shown in Figure 7-1.
