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. Customers should

validate and test 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 a projection or collection optic. Each application is derived

primarily from the optical architecture of the system and the format of the data coming into the dual DLPC3439 or

DLPC3479 controllers. The new high tilt pixel in the bottom-illuminated DMD increases brightness performance

and enables a smaller system footprint for thickness constrained applications. Applications of interest include

projection embedded in display devices like smartphones, tablets, cameras, and camcorders. Other applications

include wearable (near-eye) displays, battery powered mobile accessory, interactive display, low-latency gaming

display, and digital signage.

DMD power-up and power-down sequencing is strictly controlled by the DLPA3000/DLPA3005. Refer to Power

Supply Recommendations for power-up and power-down specifications. To ensure reliable operation, the

DLP4710 DMD must always be used with two DLPC3439 or DLPC3479 controllers and a DLPA3000 or

DLPA3005 PMIC/LED driver.

8.2 Typical Application

A pico-projector that can be used as an accessory to a smartphone, tablet or a laptop is a common application

when using a DLP4710 DMD and two DLPC3439 or DLPC3479 devices. The two DLPC3439 or DLPC3479

devices in the pico-projector receive images from a multimedia front end within the product as shown in

Figure 20.
