Mitsubishi'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.
The company says that 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, Mitsubishi also 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. The display also incorporates a plastic screen that absorbs light to maintain great visibility in bright environments.
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. 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.
Mitsubishi Electric did not announce when it planned to commercialize the new system.
