The chipset gives high brightness, colour and contrast levels and provides manufacturers with a scalable platform. 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, says TI, a new generation of HUD.
The 12-degrees FOV 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 metres ahead – to help keep the driver focused on the road.
A HUD based on the DLP3000-Q1 features the same core technology that powers more than eight out of 10 digital movie theatre screens worldwide. This results in a HUD capable of producing 15,000 candela per square meters (cd/m ²) of brightness, a dynamic dimming range of 5,000:1, high contrast >1,000:1 full on/full off (FOFO) and 125% NTSC colour-gamut performance that will not degrade over temperature, for clear images in various viewing scenarios over the typical life of the vehicle.
DLP technology does not require polarisation of light which helps automotive original equipment manufacturers (OEMs) design in HUDs with displays that are visible while wearing polarised eye-wear.
DLP technology is light source-agnostic, so it can employ reliable LEDs while providing a future path to using lasers once they are available for automotive-qualified HUD applications.
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 windscreen or combiner HUDs. This is possible across vehicle model lines, potentially resulting in greater returns on manufacturers' investments.
The DLP3000-Q1 chipset for automotive HUD applications is sampling now to 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.
