7.1 Application Information

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 DLPC8445 controller. The high tilt pixel in the bottom-illuminated DMD increases brightness performance and enables a smaller system footprint for thickness-constrained applications. Typical applications using the DLP472TP include mobile smart TVs and digital signage.

DMD power-up and power-down sequencing is strictly controlled by the DLPA3085. Refer to Section 8 for power-up and power-down specifications. To ensure reliable operation, the DLP472TP DMD must always be used with the DLPC8445 controller and a DLPA3085 PMIC.
