Liquid crystal display comprising liquid crystal lens driven at a first time period and a second time period

摘要

A display device including a liquid crystal lens and a display panel is provided. The liquid crystal lens is disposed above the display panel and includes a first substrate, a second substrate opposite to the first substrate, a liquid crystal layer between the first and the second substrates, driving electrodes located between the first substrate and the liquid crystal layer and arranged in a pitch, and an opposite electrode layer located between the second substrate and the liquid crystal layer. The display panel has display units arrange in the pitch. In a 3D display mode, two adjacent driving electrodes in the liquid crystal lens are respectively driven at a first time period and a second time period. The liquid crystal lens and the display panel are switched synchronically so that each display unit respectively displays images with different parallax at the first and the second time periods.

1. A display device comprising:
a liquid crystal lens comprising:
a first substrate;a second substrate opposite to the first substrate in a top-bottom manner;a liquid crystal layer disposed between the first substrate and the second substrate, wherein the liquid crystal layer of the liquid crystal lens defines a plurality of first lens units at a first time period and defines a plurality of second lens units at a second time period, each first lens unit and one second lens unit are arranged alternately in space and a transversal distance between the each first lens unit and the one second lens unit is substantially equivalent to a pitch;a plurality of driving electrodes located between the first substrate and the liquid crystal layer and arranged in the pitch;an opposite electrode layer located between the second substrate and the liquid crystal layer; and a display panel having a plurality of display units arranged in the pitch, the liquid crystal lens being located above the display panel, wherein under a stereo-display mode, two adjacent driving electrodes in the liquid crystal lens are driven respectively at the first time period and the second time period and the display panel is switched synchronically with the liquid crystal lens so that each display unit displays images with different parallax respectively at the first time period and the second time period, wherein the display units comprises a first display unit, a second display unit and a third display unit arranged sequentially and closely, such that at the first time period, the first display unit and the second display unit are corresponding to one of the first lens units and the third display unit is corresponding to another of the first lens units adjacent to the one of the first lens units to which the first display unit and the second display unit are corresponding.
