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.
