(1)

See the package mechanical characteristics for details regarding the size and location of the window aperture.

(2)

The active area of the device is surrounded by an aperture on the inside of the DMD window surface that masks structures of the DMD

device assembly from normal view. The window aperture is sized to anticipate several optical operating conditions. Overfill light directly

illuminating the window aperture can create adverse imaging effects, and additional device heating leading to reduced device lifetime.

Direct incident illumination should be prevented from striking the DMD window aperture.

SPACER

6.13 Chipset Component Usage Specification

requires that it be used in conjunction with the other components of the applicable DLP chipset, including

those components that contain or implement TI DMD control technology. TI DMD control technology is the TI

technology and devices for operating or controlling a DLP DMD.

Note

TI assumes no responsibility for image quality artifacts or DMD failures caused by optical system

operating conditions exceeding limits described previously.

6.14 Software Requirements

CAUTION

The DMD has mandatory software requirements. Refer to Software Requirements for TI DLP®Pico®

TRP Digital Micromirror Devices application report for additional information. Failure to use the

specified software results in failure at power up.
