  Mitsubishi Electric Develops Car Display System with Free-form Screen

Projects images on curve-, oval- or triangle-shaped screens to match interior

Business Wire

TOKYO -- February 6, 2013

Mitsubishi Electric Corporation (TOKYO:6503) announced today that it has
developed a prototype car display system with an optical engine that can
project images on curved, oval or triangular screens to suit a wide range of
car interiors.

The system's free-form screen responds flexibly to the increasing use of
curves and other design features in car interiors. At the same time, its easy
visibility helps to promote driving safety. The system incorporates display
technologies that Mitsubishi Electric fostered through its development of
rear-projection TVs as well as car electronics that withstand severe operating
conditions, ensuring high quality and reliability.

Key Developments

1) In-vehicle display flexibly matches car interiors

Mitsubishi Electric's original curve-variable optical system projects images
on screens of various shapes to minimize blur in screen areas with deep
curves. The prototype system's single optical engine adapts to a wide range of
surfaces, unlike conventional displays that require a designated optical
engine designed for a screen's specific curves or shape.

Natural, distortion-free images are projected on curved, oval or triangular
surfaces through a screen distortion adjustment process that predicts the
distortion of images caused by complex curves, and adjusts visual signal

2) Excellent resistance to high temperature, vibration and shock

To ensure steady performance and extended product life, Mitsubishi Electric
developed a hybrid cooler that combines systems for highly efficient radiation
and natural and forced-air cooling. In addition, the overall structure
minimizes distortion of the optical engine and chassis due to vibration or
shock while driving, ensuring that images remain crisp and clear. The display
also incorporates a plastic screen that absorbs light to maintain excellent
visibility in bright environments.

3) Rich colors in high-temperature conditions

The display system incorporates red, green and blue LEDs for its light source
to achieve a color gamut 1.5-times wider than conventional displays that use
white LED backlights. The three different LEDs produce brighter colors and
increased visibility. In addition, a light sensor separately controls light
emissions from the different LEDs, each having its own temperature
characteristics, and maintains color balance to stabilize color reproduction
in a wide range of temperatures.


The technologies announced in this news release encompass 11 Japanese and
three international patents pending.
