Claim Text:
1. A method for controlling a liquid crystal display (LCD), the method comprising: receiving a first light from a light source structure at a first side of a light emitting layer that includes a photo-luminescent material that emits light with different wavelengths upon excitation by the first light; emitting from the light emitting layer a first color component based on receiving the first light, a second color component based on receiving the first light, and a third color component based on receiving the first light, wherein the first, second, and third components are emitted from a second side, opposite the first side, of the light emitting layer; receiving ambient 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, wherein the ambient light is received at the second side of the light emitting layer, wherein the light emitting layer, the liquid crystal layer, and the first polarizer layer are all disposed between a bottom glass and a top glass without a glass layer intervening between the first polarizer layer and the liquid crystal layer; converting the ambient light into the first color component, the second component, and the third color component in the light emitting layer; and dynamically controlling an intensity of the first light based on the converting of the ambient light, wherein controlling the intensity comprises dynamically adjusting between a transmissive mode, a reflective mode, and a transflective mode, wherein: the reflective mode is when the first light source is in an OFF state and the liquid crystal layer is controlled to allow ambient light to be selectively incident upon the second side of the light emitting layer to convert the ambient light into the first color component, the second color component, and the third color component in the light emitting layer.
