Patent ID: 8614772

Claim:
A multi-functional liquid crystal parallax barrier device, being a liquid crystal device comprising an upper linear polarizer, an upper transparent substrate, an upper common electrode layer, an upper insulation layer, an upper barrier electrode layer, an upper alignment layer, a liquid crystal molecular layer, a lower alignment layer, a lower barrier electrode layer, a lower insulation layer, a lower common electrode layer, a lower transparent substrate, and a lower linear polarizer; wherein a double-view vertical strip parallax barrier is disposed on the liquid crystal device when a display in the liquid crystal device is oriented in a first direction and a multi-view slant-and-step parallax barrier is disposed on the liquid crystal device when the display is oriented in a second direction, so as to display a double-view 3D image in the first direction and a multi-view 3D image in the second direction, in addition to displaying a 2D image, through the control of an appropriate driving voltage; or wherein the multi-view slant-and-step parallax barrier is disposed on the liquid crystal device when the display is oriented in the first direction and the double-view vertical strip parallax barrier is disposed on the liquid crystal device when the display is oriented in the second direction, so as to display the multi-view 3D image in the first direction and the double-view 3D image in the second direction, in addition to displaying the 2D image, through the control of the appropriate driving voltage.
