The volume of possible and necessary information for the driver is increasing continuously, both in road traffic and in the vehicle itself. The global targets for reducing CO2 emissions and consumption apply more than ever before to all vehicle components, including display systems. The driver information systems in the BMW 7 Series all offer maximum image quality and are optimally tailored to the driver and the occupants.
The technologies for driver information systems in the consumer sector are developing at a rapid pace. The requirements pertaining to future display systems are increasing accordingly: For example, accessing new display areas in ergonomically favorable sections, variable and situation-related display contents, scalability in terms of size and costs, low weight and energy consumption plus high-quality depiction.
Top priority in integrating the displays into the vehicle was given to meeting the requirements for maximum image quality plus a harmonious effect and appearance in the overall interior.

All information which is shown in the Head-Up Display is generated in the instrument cluster.
The instrument cluster display to welcome the driver deserves particular attention. Whilst the instrument cluster is asleep, only the trim rings hint at the four tubes. Once the driver's door has been opened, the instrument cluster wakes up. The four tubes are initially illuminated by means of special, white corona lighting. Once the driver has taken his seat, the digits are gradually faded in.
