7 Detailed Description
7.1 Overview
The DLPC3421 part is a display controller for the DLP160CP (0.16 nHD) DMD. The DLPC3421 controller is part
of the chipset composed of the controller, DLP160CP (0.16 nHD) DMD, and DLPAxxxx PMIC (which includes
an LED driver). To ensure reliable operation of the DLP chipset, the DLPC34xx must always be used with the
supported devices shown in Table 6-1.
The DLPC34xx display controller provides interfaces along with data and image processing functions that
are optimized for small form factor and power-constrained display applications. Applications include projection
within mobile projectors, smart displays, smartphones, tablets, augmented reality glasses, mobile accessories,
smart home displays, and Pico projectors. The DLPC3421 is not a front-end processor; therefore, standalone
projectors must include a separate front-end chip to interface to the outside world (for example, a video decoder,
HDMI receiver, or USB I/F chip).
