8.2.1 Design Requirements

A pico-projector is created by using a DLP chip set comprised of a DLP4710 DMD, two DLPC3439 controllers and a DLPA3000/DLPA3005 PMIC/LED driver. The DLPC3439 controllers do the digital image processing, the DLPA3000/DLPA3005 provides the needed analog functions for the projector, and the DLP4710 DMD is the display device for producing the projected image.

In addition to the three DLP chips in the chip set, other chips are needed. At a minimum a Flash part is needed to store the software and firmware to control each DLPC3439 controller.

The illumination light that is applied to the DMD is typically from red, green, and blue LEDs. These are often contained in three separate packages, but sometimes more than one color of LED die may be in the same package to reduce the overall size of the pico-projector.

For connecting the DLPC3439 controllers to the multimedia front end for receiving images, a 24-bit parallel interface is used. An I2C interface should be connected to the multimedia front end for sending commands to one of the DLPC3439 controllers for configuring the DLPC3439 controller for different features.
