    Abstract: A liquid crystal display may have upper and lower polarizers (22, 24). A color filter layer (12) and a thin film transistor layer (14) may be located between the upper and lower polarizers. A liquid crystal layer (16) may be interposed between the color filter layer and the thin film transistor layer. A first optical film layer (18) that includes a birefringent compensating layer (62) may be located between the upper polarizer and the color filter layer. A second optical film layer (20) that may be devoid of birefringent compensating layers may be located between the thin film transistor layer and the lower polarizer. A grid of metal signal lines (66) may be used to distribute signals to thin film transistors on the thin film transistor layer. A black mask (68) may be interposed between the grid of signal lines and the thin film transistor layer.

    Abstract: One embodiment describes an electronic display that displays image frames with a first refresh rate or a second refresh rate, in which the second refresh rate is lower than the first refresh rate; a display driver that writes the image frames by applying voltage to a display panel; and a timing controller that receives first image data from an image source, in which the first image data describes a first image frame and a first desired refresh rate equal to the second fresh rate; and that instructs the display driver to apply a first set of voltage polarities to the display panel to display first image frame at the first refresh rate and to apply a second set of voltage polarities to the display the first image frame at the second refresh rate when polarity of inversion imbalance accumulated is equal to polarity of the first set of voltage polarities.

    Abstract: A method and system for temporal dithering of pixels in a display 14. The dithering of the pixels may allow for simulation of 8-bit color from a 6-bit display. Moreover, the dithering of the pixels may be selected to follow a specific pattern to minimize display artifacts, which might otherwise result from interference generated by pixel inversion techniques performed during the pixel dithering. Through application of selective dithering techniques, including utilization of specific dithering patterns, the generation of display artifacts via interference from pixel inversion techniques during the display of an image may be minimized.
