System and method for two-dimensional (2d) and three-dimensional (3d) display

A driving method for 2D/3D display applied to a 2D/3D display system including a liquid crystal layer, a first electrode section and a second electrode section arranged on a first side of the liquid crystal layer, a third electrode section arranged on a second side of the liquid crystal layer, comprising:

• receiving, by voltage output modules, image display adjustment signals, wherein the image display adjustment signals includes at least one of 2D display area position information and 3D display area position information;
• and
• based on the received image display adjustment signals, providing, by the voltage output modules, one or more driving voltages for the first electrode section, the second electrode section and the third electrode section, wherein:
• when the liquid crystal molecules in a 3D display area corresponding to the 3D display area position information form multiple lens units with refractive indexes of the liquid crystal molecules distributed in a gradient, a 3D image is displayed;
• and
• when the refractive indexes of the liquid crystal molecules in the 2D display area corresponding to the 2D display area position information are not distributed in a gradient, a 2D image is displayed.

A liquid crystal lens, comprising:

• a first substrate;
• a second substrate arranged facing the first substrate with a distance from the first substrate;
• a liquid crystal layer, including liquid crystal molecules having birefringence and anisotropy, placed between the first substrate and the second substrate;
• a first electrode group, including a plurality of first electrodes separated with a certain distance, arranged on a surface of the first substrate;
• a second electrode group, including a plurality of second electrodes separated with a certain distance, arranged on the first electrode group;
• an insulating layer disposed between the first electrode group and the second electrode group, wherein the first electrode group, the second electrode group, and the insulating layer face the second substrate;
• and
• a third electrode group, including a plurality of third electrodes separated with a certain distance, arranged on the surface of the second substrate, facing the first substrate and along a first direction.
