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

Texas Instruments DLP technology is a micro-electro-mechanical systems (MEMS) technology that modulates light using a digital micromirror device (DMD). DMDs vary in resolution and size and can contain over 8 million micromirrors. Each micromirror of a DMD can represent either one or more pixels on the display and is independently controlled, synchronized with color sequential illumination, to create stunning images on any surface. DLP technology enables a wide variety of display products worldwide, from tiny projection modules embedded in smartphones to high powered digital cinema projectors, and emerging display products such as digital signage and laser TV.

In display applications using the DLP660TE DMD the DLPA100 provides all needed analog functions including the analog power supplies and the color wheel motor driver to provide a robust and efficient display solution.

8.2 Typical Application

When the DLPA100 power management device is combined with two display controllers (DLPC4422), an FPGA, and other electrical, optical and mechanical components the chipset enables bright, affordable, full 4K UHD display solutions. The DLPA100 power management and motor driver provides power supply sequencing and controls the color wheel motors, laser and LED currents as required by the application. A typical 4K UHD system application is shown in Figure 4.

8.2.1 Design Requirements

At the high level, DLP660TE DMD systems will include an illumination source, a light engine, electronic components, and software. The designer must first choose an illumination source and design the optical engine taking into consideration the relationship between the optics and the illumination source. The designer must then understand the electronic components of a DLP660TE DMD system. A display projector is created by using a DLP chipset comprised of DLP660TE DMD, DLPC4422 controller and DLPA100 power and motor driver. The DLPC4422 does the digital image processing, the DLPA100 provides the needed analog functions for the projector, and the DMD is the display device for producing the projected image.

8.2.2 Detailed Design Procedure

For connecting together the DLPC4422 digital display controller, the DLP660TE DMD, and the DLPA100, see the reference design schematic. Layout guidelines should be followed to achieve a reliable projector. To complete the DLP system an optical module or light engine is required that contains the DLP660TE DMD, associated illumination sources, optical elements, and necessary mechanical components.
