PARALLAX BARRIER BASED STEREOSCOPIC DISPLAY DEVICE AND METHOD

摘要

A parallax barrier device includes a first electrode, a second electrode, a liquid crystal layer, a polarizer, and a controller. The first electrode includes a plurality of first sub-electrodes, and the second electrode includes a plurality of second sub-electrodes arranged intersecting the plurality of first sub-electrodes. The liquid crystal layer is disposed between the first electrodes and the second electrode, and the liquid crystal layer forms respective display windows corresponding to regions formed by the intersections of the first sub-electrodes and the second sub-electrodes. The polarizer is disposed on the first electrode or the second electrode on a side away from the liquid crystal layer. Further, the controller is coupled to the first electrodes and the second electrode and configured to control voltages on the plurality of first sub-electrodes and the plurality of second sub-electrodes to form a parallax barrier.

1. A parallax barrier device, comprising:
a first electrode including a plurality of first sub-electrodes; a second electrode including a plurality of second sub-electrodes arranged intersecting the plurality of first sub-electrodes; a liquid crystal layer disposed between the first electrodes and the second electrode, the liquid crystal layer forming respective display windows corresponding to regions formed by the intersections of the first sub-electrodes and the second sub-electrodes; a polarizer disposed on the first electrode or the second electrode on a side away from the liquid crystal layer; and a controller coupled to the first electrode and the second electrode and configured to control voltages on the plurality of first sub-electrodes and the plurality of second sub-electrodes to cause the display windows of the liquid crystal layer to have different voltage differences, such that some of incident linearly polarized light passing through the display windows passes through the polarizer and some other incident polarized light passing through the display windows does not pass through polarizer, displaying a pattern of transparent and opaque display windows to form a parallax barrier.
