Abstract
In one embodiment, a method for controlling a liquid crystal display (LCD) is provided. The method receives a first light from a light source structure at a light emitting layer and emits from the light emitting layer a first color component, a second color component, and a third color component. The method then receives a second light through a first polarizer layer of a first polarization state positioned above the light emitting layer, a liquid crystal layer positioned above the first polarizer layer, and a second polarizer layer of a second polarization state positioned above the liquid crystal layer and converts the second light into the first color component, the second component, and the third color component in the light emitting layer. An intensity of the first light is dynamically controlled based on the converting of the second light.
