TI's DLP technology, used in 85% of digital cinema displays, utilizes a matrix of tiny articulated mirrors, one for each pixel. Each of these mirrors has two controllable positions (for example +17 degrees and -17 degrees). A separate light source (LED, laser, etc.) shines on the matrix, and the mirrors within the matrix at one of the orientations reflect light at the target. These devices have been used in projection systems since 1997. See [1] and [2].
The advantage in automotive applications is that the light can be bright enough for automotive applications while allowing the illuminated area to be controlled through software. Illumination levels and regions can be modulated in response to the car's speed, steering, location, recognition of oncoming cars, etc. [3]
