DLPS099B February 2018 – May 2022 DLP3010
A pico-projector is created by using a DLP chip set comprised of DLP3010 DMD, a DLPC3433/DLPC3438 controller and a DLPA200x/DLPA3000 PMIC/LED driver. The DLPC3433/DLPC3438 controller does the digital image processing, the DLPA200x/DLPA3000 provides the needed analog functions for the projector, and DLP3010 DMD is the display device for producing the projected image.
In addition to the three DLP chips in the chip set, other chips may be needed. At a minimum a Flash part is needed to store the software and firmware to control the DLPC3433/DLPC3438 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 DLPC3433/DLPC3438 controller to the multimedia front end for receiving images, parallel interface is used. When the parallel interface is used, I2C should be connected to the multimedia front end for sending commands to the DLPC3433/DLPC3438 controller and configuring the DLPC3433/DLPC3438 controller for different features.
