Since today's trend in automotive displays is toward more, larger and better, LCD backlights have a large potential to play an important role in terms of high‐brightness, high‐contrast and power saving. In this paper, we present an efficient backlight which allows high‐luminance, high‐contrast and low power consumption utilizing our novel collimating control technology.
