Abstract
A 2D/3D switching system is provided. The 2D/3D switching system includes a 2D/3D switching device for selectively processing lights from 2D images and 3D images. The 2D/3D switching device includes a plurality of first electrodes, a plurality of second electrodes arranged corresponding to the plurality of first electrodes and separated with a distance, and a liquid crystal layer placed between the plurality of first electrodes and the plurality of second electrodes. The 2D/3D switching system also includes a driving unit coupled to the plurality of first electrodes and the plurality of second electrodes to provide driving voltages to the plurality of first electrodes and the plurality of second electrodes, and to provide at least one voltage adjustment signal to adjust corresponding driving voltages of at least one of plurality of first electrodes and the plurality of second electrodes.
