  • Patent number: 9196203
    Abstract: A sequential color LCD device for displaying a color image using at least four different primary colors, with back illumination system comprising of at least three color LEDs. The device is capable of activating at least two color LEDs simultaneously, thus obtaining additional display colors. A method is disclosed for displaying more than three colors using an LCD device having three color LEDs, in which the LED back illumination system sequentially illuminates the LC array with only a first single LED color, a simultaneous operation of first and second LED colors, and then only the second LED color. The device may drive the LC cells from a first color data value directly to a subsequent color data value directly, without driving the LC cell to zero transmittance prior to loading of the subsequent color data value. The device may correct for color phase shift and for the dependency of apparent color intensity.

  • Patent number: 8531372
    Abstract: Embodiments of the present invention provide an apparatus, system, and method of reproducing a sequence of at least first and second color image frames by controllably activating an array of liquid crystal elements, the array including at least a first liquid crystal element to reproduce first and second sub-pixel values in the first and second frames, respectively. Some demonstrative embodiments may include estimating the first sub-pixel value based on a third sub-pixel value to be reproduced in the second frame by a second liquid crystal element of the array which is shifted in relation to the first liquid crystal element by a location shift value associated with the first liquid crystal element; and generating an overdrive signal for activating the first liquid crystal element based on a combination of the first and second sub-pixel values. Other embodiments are described and claimed.
