Implementing Linux DRM drivers for DLPC3433 MIPI DSI Projectors


DLP-based projector technology has been evolved in multiple areas of applications since it provides sharp, high-quality projections with the potential for 3D capabilities.

Most of them are Texas Instrument chipsets based on optical micro-electro-mechanical technology that uses a digital micromirror device.

DLPC3433 is one of the newer DPL-based MIPI DSI projectors which uses most industrial and consumer electronics.


DLPC3433 block has three key sets of subsystems,

  1. DLPC3433, interfaced from front-end SoC or other chipsets via Parallel, DSI for video, and I2C, SPI for configurations.
  2. DLPA3000 is PMIC and High-CurrentLED driver
  3. DMD, digital mirror device for Sub-LVDS output optics generation.

All the above subsystems are required to implement on respective Linux DRM driver stacks to function properly.
