摘要：
A dual view zone backlight and dual-mode display employ a first backlight region to provide directional emitted light toward a first view zone and a second backlight region to provide broad-angle emitted light toward the first and a second view zone in a first mode. The dual-mode display includes a second backlight to provide broad-angle light toward both the first view zone and the second view zone in a second mode.
