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

(3)

The active area of the DLP4710 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 aperture is sized to anticipate several optical conditions. Overfill light illuminating the

area outside the active array can scatter and create adverse effects to the performance of an end application using the DMD. The

illumination optical system should be designed to limit light flux incident outside the active array to less than 10% of the average flux

level in the active area. Depending on the particular system's optical architecture and assembly tolerances, the amount of overfill light on

the outside of the active array may cause system performance degradation.

6.13 Chipset Component Usage Specification

The DLP4710 device is a component of one or more DLP chipsets. Reliable function and operation of the device

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 DLP4710 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 will result in failure at

power up.
