P‐51: A Novel Backlight Unit for LCD Used in Virtual Reality

Abstract

With the expansion of the markets about near‐eye display devices and other similar consumer devices, the highly optical efficiency and display performance of these devices have also received more and more attention and challenge. So in this paper, a novel backlight unit for liquid crystal display (LCD) is reported. The angle of the radiation can change with the position of the active area (AA) in two directions. The change range of the chief radiation angle can vary more than ±20°. In the meanwhile, with the same power consumption, the brightness of the backlight can achieve or exceed the existing brightness level of the backlight.
