Projection technology in car headlights

Projection technology has been applied to the headlights of some new energy vehicles, such as displaying animations such as pedestrian paths and turn prompts. This is mainly achieved through DLP modules or Microled modules. The pixels of DLP modules are in the millions, and the cost is relatively high. Currently, only TI has mass-produced DLP solutions. MicroLED modules are provided by Osram and Nichia. Their solutions have similar architectures, both of which are based on receiving data from the MCU and forwarding it to the driving circuit inside the light source, and then the light source displays according to the received data.
