The DLPC120-Q1 DMD display controller for automotive applications is part of a chipset compatible with one of three digital micromirror devices (DMDs), DLP3030-Q1, DLP3020-Q1, or DLP3021-Q1. The core DLPC120-Q1 logic is responsible for accepting video input and formatting the data to display on the DMD while simultaneously controlling RGB LEDs in order to create a real-time image. The DLPC120-Q1 is also responsible for controlling the power-up and power-down events of the DMD, based on external system control or temperature input from the DMD. Combined with an external dimming circuit and microcontroller, the DLPC120-Q1 supports a wide dimming range > 5000:1 for HUD applications. Typically, the DLPC120-Q1 is a peripheral device in an I2C interface with a host processor.
