7.1 Application Information

Digital micromirror devices (DMDs) are spatial light modulators that 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 two DLPC4420 display controllers. Typical applications using the DLP781TE DMD include smart projectors, enterprise projectors, large venue projectors, and digital signage.

The DLPC4420 display controller controls DMD power-up and power-down sequencing through the DLPA300 DMD. Refer to Section 7.4 for power-up and power-down specifications. For reliable operation, always use the DLP781TE DMD with two DLPC4420 display controllers, a DLPA100 PMIC/motor driver, and a DLPA300 micromirror driver.
