Abstract
The invention provides a parallax barrier automatic three-dimensional display, which includes multiple first electrodes that are arranged on a first base plate and extends in the first direction, multiple second electrodes that are arranged on a second base plate and extends in the second direction parallel with the extending direction of a scanning line, and a liquid crystal layer that is arranged between the first and the second base plates and rotates through the voltage difference between the first electrodes and the second electrodes, so as to shield the light or allow the light to penetrate through, wherein the multiple first electrodes are divided into odd electrodes and even electrodes; the multiple second electrodes are divided into odd electrodes and even electrodes; and the images of the neighboring viewing fields are switched through the voltage potential change of the second odd electrodes and the second even electrodes. By adopting the parallax barrier automatic three-dimensional display, as only the respective voltage potentials of the odd electrodes and the even electrodes of the second electrodes are changed to switch the images of the neighboring viewing fields without the need of controlling the first electrodes one by one, the three-dimensional image can be displayed without reducing the resolution of the display.
