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 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. Each application is derived

primarily from the optical architecture of the system and the format of the data coming into the the DLPC2607

controller. Applications of interest include internet of things (IoT) devices such as control panels, and security

systems and thermostats, as well as projection embedded in display applications like smartphones, tablets,

cameras, and artificial intelligence (AI) assistance. Other applications include wearable (near-eye) displays,

micro digital signage, and ultra-low power smart accessory projectors.

DMD power-up and power-down sequencing is strictly controlled by the DLPA1000. Refer to Section 9 for

power-up and power-down specifications. The DLP2000 DMD reliability is only specified when used with the

DLPC2607 controller and the DLPA1000 PMIC/LED Driver.

8.2 Typical Application

A common application for the DLP2000 chipset is creating a pico-projector embedded in a handheld product. For

example, a pico-projector embedded in a smart phone, camera, battery powered mobile accessory, micro digital

signage or IoT application. The DLPC2607 controller in the pico-projector receives images from a multimedia

front end within the product as shown below.

8.2.1 Design Requirements

A pico-projector is created by using a DLP chip set comprised of the DLP2000 DMD, a DLPC2607 controller,

and a DLPA1000 PMIC/LED driver. The DLPC2607 controller does the digital image processing, the DLPA1000
