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.

Application Information

The DLP7000UV devices require they be coupled with the DLPC410 controller to provide a reliable solution for many different 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 a projection collection optic. Each application is derived primarily from the optical architecture of the system and the format of the data coming into the DLPC410. Applications of interest include lithography, 3D Printing, medical systems, and compressive sensing.

DMD Reflectivity Characteristics

TI assumes no responsibility for end-equipment reflectivity performance. Achieving the desired end-equipment reflectivity performance involves making trade-offs between numerous component and system design parameters. DMD reflectivity characteristics over UV exposure times are represented in Figure 18.

2.3 W/cm2, 363 to 400 nm
Figure 18. Nominal DMD Relative Reflectivity Percentage and Exposure Hours

DMD reflectivity includes micromirror surface reflectivity and window transmission. The DMD was characterized for DMD reflectivity using a broadband light source (200-W metal-halide lamp). Data is based off of a 2.3-W/cm2 UV exposure at the DMD surface (363-nm peak output) using a 363-nm high-pass filter between the light source and the DMD. (Contact your local Texas Instruments representative for additional information about power density measurements and UV filter details.)

Design Considerations Influencing DMD Reflectivity

Optimal, long-term performance of the digital micromirror device (DMD) can be affected by various application parameters. Below is a list of some of these application parameters and includes high level design recommendations that may help extend relative reflectivity from time zero:

  • Illumination spectrum – using longer wavelengths for operation while preventing shorter wavelengths from striking the DMD
  • Illumination power density – using lower power density
  • DMD case temperature – operating the DMD with the case temperature at the low end of its specification
  • Cumulative incident illumination – limiting the total hours of UV illumination exposure when the DMD is not actively steering UV light in the application. For example, a design might include a shutter to block the illumination or LED illumination where the LEDs can be strobed off during periods not requiring UV exposure.
  • Micromirror landed duty cycle – applying a 50/50 duty cycle pattern during periods where operational patterns are not required.

Design Requirements

All applications using the DLP7000UV chipset require both the controller and the DMD components for operation. The system also requires an external parallel flash memory device loaded with the DLPC410 Configuration and Support Firmware. The chipset has several system interfaces and requires some support circuitry. The following interfaces and support circuitry are required:

  • DLPC410 system interfaces:
    • Control interface
    • Trigger interface
    • Input data interface
    • Illumination interface
    • Reference clock
  • DLP7000UV interfaces:
    • DLPC410 to DLP7000UV digital data
    • DLPC410 to DLP7000UV control interface
    • DLPC410 to DLP7000UV micromirror reset control interface
    • DLPC410 to DLPA200 micromirror driver
    • DLPA200 to DLP7000UV micromirror reset

Device Description:

The DLP7000UV XGA chipset offers developers a convenient way to design a wide variety of industrial, medical, telecom and advanced display applications by delivering maximum flexibility in formatting data, sequencing data, and light patterns.

The DLP7000UV XGA chipset includes the following four components: DMD Digital Controller (DLPC410), EEPROM (DLPR410), DMD Micromirror Driver (DLPA200), and a DMD (DLP7000UV).

DLPC410 Digital Controller for DLP Discovery 4100 chipset

  • Provides high speed LVDS data and control interface to the DLP7000UV.
  • Drives mirror clocking pulse and timing information to the DLPA200.
  • Supports random row addressing.

DLPR410 PROM for DLP Discovery 4100 chipset

  • Contains startup configuration information for the DLPC410.

DLPA200 DMD Micromirror Driver

  • Generates Micromirror Clocking Pulse control (sometimes referred to as a Reset) of DMD mirrors.

DLP7000UV DLP 0.7XGA 2xLVDS UV Type-A DMD

  • Steers light in two digital positions (+12° and –12°) using 1024 × 768 micromirror array of aluminum mirrors.

Reliable function and operation of DLP7000UV XGA chipsets require the components be used in conjunction with each other. This document describes the proper integration and use of the DLP7000UV XGA chipset components.

The DLP7000UV XGA chipset can be combined with a user programmable Application FPGA (not included) to create high performance systems.

Detailed Design Procedure

The DLP7000UV DMD is designed with a window which allows transmission of Ultra-Violet (UV) light. This makes it well suited for UV applications requiring fast, spatially programmable light patterns using the micromirror array. UV wavelengths can affect the DMD differently than visible wavelengths. There are system level considerations which should be leveraged when designing systems using this DMD.
