ZHCSIP9C July 2018 – May 2022 DLP230KP
A pico projector is created by using a DLP chipset comprised of a DLP230KP DMD, a DLPC3434 controller, and a DLPA2000/2005/3000 PMIC/LED driver. The DLPC3434 controller performs the digital image processing, the DLPA2000/2005/3000 provides the needed analog functions for the projector, and the DLP230KP DMD is the display device for producing the projected image.
In addition to the three DLP chips in the chipset, other chips are needed. At a minimum a flash part is needed to store the DLPC3434 controller software.
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.
The DLPC3434 controller receives image data from the multimedia front end over a 24-bit parallel interface. An I2C interface should be connected from the multimedia front end for sending commands to the DLPC3434 controller for configuring the chipset for different features.
