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 temporal manner during a frame.

Abstract: A method for displaying an input image on a display includes receiving the input image to be displayed on the display. The image is modified with a first process to determine a driving signal for a two-dimensional backlight array of independently selectable light emitting elements of the display. The first modified image is modified with a second noise reducing process to determine a driving signal for a two-dimensional liquid crystal layer defining pixels of the display. The two-dimensional backlight array has a different density of light emitting elements than the two-dimensional liquid crystal layer defining the pixels of the display.

Abstract: Elements of the present invention relate to systems and methods for determining device white point and gamma correction curve characteristics.

Abstract: A display device is provided that includes a plurality of pixels, where each pixel includes a single subpixel. In a first aspect, a single subpixel is able to sequentially generate a plurality of (e.g., at least three) primary colors. As a result of the single subpixel, the display is able to supply a gamut of colors including at least 3 primaries colors. For example, the sequential generation of the 3 primary colors may involve operating the subpixel in a time division multiplex (TDM) mode, and a primary combination color is supplied in response to the subpixel generating 2 primary colors in respective TDM subframes. When the pixel includes at least two neighboring subpixels, the pixel may additionally be operated in a spatial division multiple (SDM) mode or in the TDM mode.

Abstract: A backlight display has improved display characteristics. An image is displayed on the display which includes a liquid crystal material with a light valve. The display receives an image signal, modifies the light valve with an overdrive for a first region of the image based upon the timing of the illumination of the region, and modifies the light valve with an overdrive for a second region of the image based upon the timing of the illumination of the second region.

Abstract: A backlit display with improved dynamic range. The disclosed display illuminates a pixel of the display at respective non-zero illumination levels during each of a first frame and a second frame and decreases the illumination level of the pixel during the interval between the first frame and the second frame.

Abstract: A display system includes a building, a wall enclosed within the building, and a light guide directing light from the exterior of the building to the wall within the building. A display is supported proximate the wall where the display includes a liquid crystal layer and not including a backlight. The light guide directing the light to the liquid crystal layer is in such a manner that the combination of the light and the liquid crystal layer results in an image displayed thereon.

Abstract: Aspects of the present invention relate to systems and methods for performing white balance operations for an LED display backlight. Some aspects related to an iterative process wherein display backlight luminance and color are sampled at an intermediate resolution between the resolution of the LED backlight and the resolution of the LCD display. Some aspects relate to a process wherein r, g and b driving value differences are determined using a deconvolution technique.

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.
