Abstract

A display includes a plurality of pixel circuits, each pixel circuit including a first electrode, a second electrode, a reflective region, and a transmissive region. The reflective region reflects ambient light and includes a first portion of a liquid crystal layer and a polarization dependent reflector. The transmissive region transmits backlight and includes a second portion of the liquid crystal layer. A dielectric layer is between the first and second electrodes in one of the reflective region and the transmissive region, the dielectric layer configured such that when a pixel voltage is applied to the first and second electrodes, the percentage of the pixel voltage applied across the first portion of the liquid crystal layer is different from the percentage of the pixel voltage applied across the second portion of the liquid crystal layer. The display includes a backlight module to generate the backlight.
