    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: Disclosed is reflective morphable display with multi-layered depth viewing, low power consumption and few components and a method of activating various features thereof. The disclosed display includes a bi-stable reflective cholesteric liquid display crystal (ChLCD) layered in combination with a display device such as an LCD and a quarter lambda (λ/4) retardation film layer. Linearly polarized light emerging from the front surface of a display device is circularly polarized by the λ/4 layer before entering the ChLCD layer. In its reflective state, the ChLCD layer receiving a portion of the ambient light having the same handedness of the ChLCD is reflected in a mirror-like manner. Also in its reflective state, when it receives light that is circularly polarized by the λ/4 retardation film layer, the ChLCD layer acts as a shutter. A display device with depth viewing is provided as the ChLCD layer pixelated so it is configured to display font and/or other indicia.

    摘要: An multi-touch detection system (100) separately determines each of the coordinates of multiple touches and is able to correctly pair the coordinates, the touch panel includes multiple (e.g., two or four) separate sections (104, 106, 404, 406, 504, 506, 508, 510) to detect touches in different areas. The system (100) is able to operate at high refresh rates allowing speed sensitive applications to be supported.

    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.
