  • Patent number: 8199100
    Abstract: Desirable control of displays is facilitated. According to an example embodiment of the present invention, a light arrangement provides light to form an image using a plurality of light sources (e.g., light generating or producing elements), a control arrangement and an attenuation arrangement. Each light source provides light for a portion of the image and the control arrangement independently controls the amount of light generated by each source according to a brightness of the portion of the image for which each source is providing light and, for certain embodiments, facilitating desirable power savings and/or contrast. The attenuation arrangement selectively passes light from the light sources to form the image.
