    摘要: A method and apparatus are provided for correcting burn-in in a flat screen display. The method includes the steps of determining a maximum cumulative luminance of each pixel (15) within the display (14) based upon a usage of the pixel, providing a modulation map (40) of the display (14) from the maximum cumulative luminance of each pixel (15) within the display (14), transforming the modulation map (40) based upon the maximum cumulative luminance of groups of adjacent pixels to provide a modulation index for each pixel location of the map (40), comparing the modulation indexes with a set of threshold values and adjusting a luminosity of associated pixels (15) of the display (40) when the modulation index exceeds the threshold.

    摘要: An electronic device (200) includes a display (202) and an LC shutter (204), at least a portion of which is operatively positioned over the display (202). The LC shutter (204) provides switching between a transparent state and a diffusive state with high image integrity, and high transmission in the transparent state. In one embodiment, the electronic device (200) further includes control logic (206) operatively coupled to the LC shutter (204) to provide control signals (212) to the LC shutter (204) to effect the transparent state. The LC shutter (204) includes a first dichroic polarizer (300), such as a broadband dichroic polarizer, an LC cell (304), and a diffusive reflective polarizer (307). The LC cell (304) is interposed between the first dichroic polarizer (300) and the diffusive reflective polarizer (307). Related methods are also set forth.
