Abstract
A dual liquid crystal barrier includes a first substrate having space-division electrodes, the space-division electrodes including first electrodes and second electrodes, a second substrate having time-division electrodes, the time-division electrodes including third electrodes and fourth electrodes, and a liquid crystal layer between the first substrate and the second substrate. The dual liquid crystal barrier is configured to selectively operate as a space-division liquid crystal barrier based on the space-division electrodes, or a time-division liquid crystal barrier based on the time-division electrodes.
Claims20
A dual liquid crystal barrier, comprising:
- a first substrate having space-division electrodes, the space-division electrodes including first electrodes and second electrodes;
- a second substrate having time-division electrodes, the time-division electrodes including third electrodes and fourth electrodes;
- and
- a liquid crystal layer between the first substrate and the second substrate,
- wherein the dual liquid crystal barrier is configured to selectively operate as a space-division liquid crystal barrier based on the space-division electrodes, or a time-division liquid crystal barrier based on the time-division electrodes.
A stereoscopic image display device, comprising:
- a dual liquid crystal barrier configured to selectively operate as a space-division liquid crystal barrier based on space-division electrodes, or as a time-division liquid crystal barrier based on time-division electrodes;
- a display panel configured to fix positions of pixels for outputting a left image and positions of pixels for outputting a right image when the dual liquid crystal barrier operates as the space-division liquid crystal barrier, and configured to alternately change the positions of the pixels for outputting the left image and the positions of the pixels for outputting the right image when the dual liquid crystal barrier operates as the time-division liquid crystal barrier;
- and
- a peripheral circuit configured to control operations of the dual liquid crystal barrier and operations of the display panel.
