The system’s three LED free-form screen responds flexibly to the increasing use of curves and other design features in car interiors. It uses display technologies from rear-projection TVs as well as car electronics that withstand severe operating conditions, ensuring high quality and reliability, and the company has 11 Japanese patents and three international patents pending.
The ‘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 input.
To ensure steady performance and extended product life, Mitsubishi has also developed a hybrid cooler that combines 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.Free form screen
The display system (above) 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.
