    Abstract: A liquid crystal display includes a backlight that provides light and selectively modifies the transmission of light from the backlight to the front of the display. The backlight includes a plurality of spaced apart light waveguides and a plurality of selection elements associated with the light waveguides that change the characteristics of the material of the light waveguides to selectively direct the transmission of light toward the liquid crystal layer. The combination of the waveguides and the selection elements provide light to the front of the display in a non-uniform temporal manner and a non-uniform spatial manner during a frame.

    Abstract: A system for influencing a state of a user includes a display with a light source for emitting light influencing the state of the user. A light controller selectively controls the emission of the light including at least one of; (1) the spectrum of the light; (2) the duration of the light; 3) the distribution of the light; (4) the intensity of the light; and (5) the timing of the light. An analysis engine capable of providing a signal to the light controller indicating a desired emission of the light based upon selectively illuminating one or more of a plurality of different blue light sources, each of which having a different peak spectrum.

    Abstract: Aspects of the present invention relate to systems and methods for performing white balance operations for an LED display backlight. One method comprises obtaining display parameters and capturing sensor data for a display. Geometrical calibration between the captured sensor data and the display is performed. Color conversion matrices for the display backlight may also be calculated. The backlight is displayed at a selected white value and measurement of the actual color of the backlight is then performed. Next a target luminance is determined based on the measured backlight color and minimization of visible luminance variation. A target color is then determined and used to determine a color difference between the measured backlight color and the target color. From this a normalized RGB color difference and RGB color difference driving values are determined. New RGB driving values based on the RGB color difference values and original driving values are then determined.
