ABSTRACT:
An improved stereoscopic display apparatus and methodology includes an array of liquid-crystal-based transmissive pixels are cleared (i.e., placed in a “dark” state) before being loaded with the desired analog voltage potential signal for display during both left perspective image display periods and right perspective image display periods. In this manner, cross-frame image interference between the left and right perspective images is avoided and the quality of the stereoscopic viewing experience is improved. In another aspect, an improved stereoscopic display apparatus and methodology includes an array of liquid-crystal-based transmissive pixels. During right perspective image display periods, the pixels of the array are loaded with analog voltage potential signals corresponding to a left perspective image while displaying the preceding right perspective image. Likewise, during left perspective image display periods, the pixels of the array are loaded with analog voltage potential signals corresponding to a right perspective image while displaying the preceding left perspective image. In this manner, cross-frame image interference is avoided and the left and right perspective image display periods can be expanded.
