Patent ID: 8866979

Claim:
A 2D/3D display device, comprising: a liquid crystal parallax barrier comprising a light transmission region and a light blocking region; a backlight unit; and a transflective film disposed between the parallax barrier and the backlight unit, wherein the transflective film has a variable transmission/reflection state with respect to a brightness on an opposite side of the transflective film relative to incident light from the backlight unit, such that the transflective film is transmissive if the opposite side of the transflective film relative to incident light from the backlight unit is bright, and the transflective film is reflective if the opposite side of the transflective film is dark, wherein, in a 3D display mode, stripes consisting of alternating light transmissive regions and light blocking regions being generated on the liquid crystal parallax barrier, and the transflective film being reflective at positions corresponding to the light blocking regions; and in a 2D display mode, an entirety of the liquid crystal parallax barrier being transmissive, and an entirety of the transflective film being transmissive.
