1. A system for lighting an electronic display, the system comprising:

  • an electronic display with a viewing surface and a backlight;

    a power source operatively connected to said backlight such that the result of an increase in power to said backlight is an increase in the amount of illumination output from the backlight, and the result of a decrease in power to said backlight is a decrease in the amount of illumination output from said backlight;

    a sensor adapted to measure ambient light;

    a sensor adapted to measure light emitted by said backlight; and

    a software driver in operative communication with said sensors and said power source;

    wherein the software driver is configured to access a database indicating a range of a preferred amount of backlight illumination for a given amount of ambient light, to automatically increase the power of said power source when the amount of backlight illumination is below said preferred illumination range for the sensed amount of ambient light at a given time, and to decrease the power of said power source when the amount of backlight illumination is above said preferred illumination range for the sensed amount of ambient light at a given time.
