7.2.5 Detailed Design Procedure

For a complete DLP system, an optical module or light engine is required that contains the DLP3944-Q1 DMD, associated illumination sources, optical elements, and necessary mechanical components.

To ensure reliable operation, the DMD must always be used with DLPC431 display controller and DLPA3085 / DLPA3082 PMIC driver.
