How does DLP technology work?
At the heart of every DLP chipset is an array of highly reflective aluminum micromirrors known as the digital micromirror device (DMD). The DMD is an electrical input, optical output micro-electrical-mechanical system (MEMS) that allows developers to perform high speed, efficient, and reliable spatial light modulation. Using TI's proven semiconductor manufacturing capabilities, each DMD contains up to 8 million individually controlled micromirrors built on top of an associated CMOS memory cell.
During operation, the DMD controller loads each underlying memory cell with a '1' or a '0'. Next, a mirror reset pulse is applied, which causes each micromirror to be electrostatically deflected about a hinge to the associated +/- degree state. The deflection angle of these two valid states is very repeatable due to a physical stop against two spring tips.
- In a projection system, the + degree state corresponds to an 'on' pixel, and the - degree state corresponds to an 'off' pixel. Grayscale patterns are created by programming the on/off duty cycle of each mirror, and multiple light sources can be multiplexed to create full RGB color images.
- In other applications, the +/- degree states offer two general purpose output ports with a pattern and its inverse.
The TI DLP portfolio offers chips with +/-12° states as well as +/-17° states. The newest TRP micromirror architecture, with +/- 17° states, is an exciting addition as it enables smaller DMDs that are well suited for more portable end equipment needing good brightness and power efficiency.

What’s included in a DLP chipset?
DLP chipsets allow users to obtain the maximum pattern rates for the associated DMD(s), as well as the ability to synchronize pattern display with external sensors, cameras, motors, or other devices. Furthermore, developers also benefit from TI's extensive knowledge about how to reliably drive the micromirrors across a wide range of operating conditions.
The DLP chipset includes:
- DMD – Digital micromirror device
- DMD Controller – provides the convenient interface for reliable, high speed control of the micromirrors
- DMD Micromirror Drivers – deliver analog clocking and reset signals
- Configuration PROM – configures select DMD Controllers (sold as a programmed IC or offered as downloadable firmware)
