ZHCSJ26 November 2018 DLP3310
A pico-projector is created by using a DLP chip set comprised a DLP3310 DMD, two DLPC3437 controllers, a XC7Z020-1CLG484I4493 FPGA, and a DLPA3000/DLPA3005 PMIC/LED driver. The XC7Z020-1CLG484I4493 FPGA and DLPC3437 controllers do the digital image processing, the DLPA3000/DLPA3005 provides the needed analog functions for the projector, and the DLP3310 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 the XC7Z020-1CLG484I4493 FPGA, and each of the DLPC3437 controllers.
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 XC7Z020-1CLG484I4493 FPGA to the multimedia front end for receiving images, either a 24-bit parallel interface can be used, or the dual FPD-Link interface can be used. An I2C interface should be connected from the multimedia front end for sending commands to one of the DLPC3437 controllers for configuring the chipset for different features.
