Abstract
An electronic display comprises a backlight unit and a liquid crystal (LC) layer, wherein the backlight combines and directs light from a plurality of light sources towards the LC layer, which controls an amount of light to be displayed. The light sources comprise at least two different types of light sources associated with different wavelength ranges, to provide improved spectrum intensity for a wider range of wavelengths. The intensity of the light sources may be adjusted based upon the input data for an image to be displayed. For example, the light sources may be dimmed based upon a determined amount of the received image data associated with a particular gray level.
