8 Application and Implementation

Note

Information in the following applications sections is not part of the TI component specification,

and TI does not warrant its accuracy or completeness. TI’s customers are responsible for

determining suitability of components for their purposes, as well as validating and testing their design

implementation to confirm system functionality.

8.1 Application Information

The DLPC34xx controller is used with the DLP160AP DMD to provide a reliable display solution for many data

and video display applications. The DMDs are spatial light modulators which reflect incoming light from an

illumination source to one of two directions, with the primary direction being into projection or collection optics.

The optical architecture of the system and the format of the image digital data coming into the DLPC34xx are

what primarily determine the application requirements.

Mobile projector, Smart display, Smartphone, Tablet (multimedia), Augmented reality glasses, Smart home

display, or Pico projector.

8.2 Typical Application

A common application when using the DLPC34xx controller with the DLP160AP DMD and the DLPAxxxx

PMIC/LED driver is to create a pico projector embedded in a handheld product. For example, a pico projector

may be embedded in a smartphone, a tablet, or a camera. The controller in the pico projector embedded module

typically receives images from a host processor within the product.
