43‐1: Automotive Autostereoscopic 3D Display

Abstract

The new S‐Class introduced a newly developed 3D instrument cluster display as one of its highlights. The display enables real depth perception without the need for glasses and without compromising visual quality. This paper describes the requirements, system design and technical realization of a fully position‐adaptive autostereoscopic display.

“…Among others, these factors led to the selection of LCD technology for the driver display application and further development of a RGBW-stripes notch-type LCD with direct matrix backlight [7]. It consists of a combination of a dedicated local dimming algorithm (44-block LEDs) with local boost and ambient light adaptive RGBW conversion.…”

“…1. Two different color spaces and the brightness-depended color shift of a RGBW LCD must be handled in order to achieve a uniform user experience: the proprietary automotive HMI-HDR algorithm (a-HDR) based on the light adaptive RGBW algorithm allows a dynamic color adjustment and white point shift to optimize image and information perception from driving at night to direct sunlight conditions [7].…”

“…Using an LCD RGBW pixel structure with a local dimming backlight can highly increase display brightness and reduce power consumption and heat in automotive displays 3 . Among other factors, this led to the selection of LCD technology for the driver display application and further development of a RGBW‐stripes notch‐type LCD with direct‐matrix backlight 4 . It consists of a combination of dedicated local dimming with local boost and ambient light‐adaptive RGBW conversion.…”

“…First, two different color spaces and the luminance‐dependent color shift of an RGBW LCD must be addressed to achieve a uniform user experience. Solving this, a proprietary automotive human‐machine interface (HMI)‐high dynamic range (HDR) algorithm (a‐HDR) based on the light‐adaptive RGBW algorithm was developed that allowed a dynamic color adjustment and white point shift to optimize image and information perception from driving at night to direct sunlight conditions 4 …”
