Texas Instruments DLPC120-Q1 Automotive DMD Display Controller
Texas Instruments DLPC120-Q1 Automotive Digital Micromirror Devices (DMD) Display Controller is part of a chipset compatible with one of three DMDs (DLP3030-Q1, DLP3020-Q1, or DLP3021-Q1). The core DLPC120-Q1 logic accepts video input and formats the data to display on the DMD while simultaneously controlling RGB LEDs to create a real-time image. The DLPC120-Q1 is also responsible for controlling the power-down and power-up events of the DMD based on external system control or temperature input from the DMD. With a microcontroller and an external dimming circuit, the DLPC120-Q1 supports a wide dimming range > 5000:1 for HUD applications. Typically, the Texas Instruments DLPC120-Q1 is a peripheral device in an I2C interface with a host processor.
