7.2.1 Design Requirements

Other core components of the display system include an illumination source, an optical engine for the illumination and projection optics, other electrical and mechanical components, and software. The type of illumination used and desired brightness have a major effect on the overall system design and size.

The display system uses the DLP472TE as the core imaging device and contains a 0.47-inch array of micromirrors. The DLPC7540 controller is the digital interface between the DMD and the rest of the system, taking digital input from the front-end receiver and driving the DMD over a high-speed interface. The DLPA100 PMIC serves as a voltage regulator for the controller, and color filter wheel and phosphor wheel motor control. The TPS65145 provides the DMD reset, offset, and bias voltages. The LMR33630C provides 1.8V power to the DLP472TE.
