Abstract
A display device includes a first backlight, a viewing angle control assembly disposed on the first backlight, a second backlight disposed on the viewing angle control assembly, and a display panel disposed on the second backlight. In a security mode, only the first backlight may be operable with the viewing angle control assembly having light blocking areas that limit light transmission to the display panel to within a predetermined range to limit a viewing angle of images displayed on the display panel. In a sharing mode, the second backlight is operated and the viewing angle control assembly does not limit light transmission, thus widening the viewing angle of images on the display panel. The display device may also include an anti-condensation layer on the second backlight to improve durability in high temperature and high humidity environments.
