TI New DLP Chipset for HUDs Enables Wider LED Applications

Texas Instruments (TI) today introduced the first DLP® chipset engineered and qualified for automotive head-up display (HUD) applications. Combining the award-winning imaging qualities of DLP technology with automotive reliability, the new chipset enables head-up displays with the industry's widest field of view (FOV) up to 12 degrees. It also enables high brightness, color and contrast levels and provides manufacturers with a scalable platform. For more information, seewww.ti.com/headupdisplay.

The DLP3000-Q1 chipset consists of a DLP 0.3-inch wide video graphics array (WVGA) digital micromirror device (DMD) and DLPC120 controller and enables a new generation of HUD with benefits that include:

The widest FOV in the industry:

·         The flexibility of the DLP3000-Q1 allows for the industry's widest FOV HUD range, up to 12 degrees. A wide FOV HUD of this range allows augmented-reality elements such as navigational indicators and real-time landmark details to be displayed in the driver's line of sight – with a depth perception of 2 to 20 meters ahead – to help keep the driver focused on the road.

Outstanding brightness, dynamic range and color accuracy:

·         A HUD based on the DLP3000-Q1 features the same core technology that powers more than eight out of 10 digital movie theater screens worldwide. This results in a HUD capable of producing 15,000 candela per square meters (cd/m2) of brightness, a dynamic dimming range of 5,000:1, high contrast >1,000:1 full on/full off (FOFO) and 125 percent National Television System Committee (NTSC) color-gamut performance that will not degrade over temperature for clear images in various viewing scenarios over the typical life of the vehicle.

·         In addition, DLP technology does not require polarization of light which helps automotive original equipment manufacturers (OEMs) design in HUDs with displays that are visible while wearing polarized eye-wear.

Scalability:

·         Because DLP technology is light source-agnostic, it can leverage reliable light-emitting diodes (LEDs) while providing a future path to using lasers once they are available for automotive-qualified HUD applications.

·         In addition, with the DLP3000-Q1 as the core component of the HUD picture generation unit (PGU), the whole system can be integrated into a variety of mechanical form factors such as a windshield or combiner HUDs. This is possible, across vehicle model lines, potentially resulting in greater returns on manufacturers' investments.

To accelerate end-product development, TI maintains an extensive ecosystem of design houses. The DLP Design Network provides developers a diverse network to support their hardware and software integration, optics design, system integration, prototyping, manufacturing services, and turnkey solutions to support current and evolving customer needs.

Availability and package
The DLP3000-Q1 chipset for automotive HUD applications is sampling now with automotive manufacturers and tier-one suppliers. The DLP 0.3-inch WVGA DMD will be offered in a Type A package and the DLPC120 will be available in a ZXS package.
