摘要： A liquid crystal panel and the array substrate thereof are disclosed. The array substrate includes a switch controller respectively connects with the first scanning line and the second scanning line. In the 2D displaying mode, the switch controller turns on the first scanning line and the second scanning line in turn. In the 3D displaying mode, the switch controller turns on the first scanning line, and turns off the second scanning line. With such configuration, the flicker issues in the 3D displaying mode may be improved and the manufacturing cost is prevented from getting higher.

摘要： A monocular stereoscopic camera according to the present invention uses a macro lens capable of performing proximity expansion shooting as a third image formation lens assembly or a telephoto lens having, in combination with a second image formation lens assembly, the characteristics of a macro lens. Thus, the monocular stereoscopic camera has an advantage in that the camera can use various first image formation lens assemblies, reduce a vignetting phenomenon, reduce the entire length thereof, remove n adjustment parameter, which is repetitive and replaceable, from among parameters requiring adjustment of an optical axis, and distinguish a parameter to be adjusted during shooting and an adjustment parameter which may be fixed during shooting once after adjustment, from each other. Thus, the camera can be easily and simply manipulated and operated and has a simple structure.

摘要： Dual-direction collimation and a dual surface collimator provide dual-direction collimated light at a non-zero propagation angle. The dual surface collimator includes an entrance surface and a reflector surface each having a curved shape. The entrance surface is configured to refract incident light and the reflector surface is configured to reflect the refracted light back toward the entrance surface. The entrance surface is further configured to re-reflect the reflected light by total internal reflection toward an output aperture. Curved shapes and relative orientation of the entrance and reflector surfaces, in combination, are configured to convert the incident light into dual-direction collimated light having the non-zero propagation angle. A three-dimensional (3D) display includes the dual surface collimator, a plate light guide and an array of multibeam diffraction gratings to provide a plurality of light beams corresponding to different 3D view of the display.

摘要： A display device includes a display panel, a first polarizer, a liquid crystal lens, a first quarter-wave plate, and a second quarter-wave plate. The display panel displays an image. The first polarizer disposed on the display panel reflects a first light having a polarization direction parallel to a reflection axis of the first polarizer. The liquid crystal lens includes liquid crystal molecules and changes a phase of the first light or a second light according to a driving signal applied to the liquid crystal lens. The second and first lights travel in opposite directions with respect to each other. The first quarter-wave plate is disposed between the first polarizer and the liquid crystal lens. The second quarter-wave plate is disposed between the liquid crystal lens and a second polarizer. The display device operates in a mirror mode, a three-dimensional mode, and a two-dimensional mode according to the driving signal.

摘要： An embodiment of the present invention provides a 3D panel. The 3D panel includes a first substrate, a second substrate, and liquid crystals configured to be filled between the first substrate and the second substrate, wherein both the first substrate and the second substrate are provided with a common electrode and a signal electrode. Since the substrates at two sides of the 3D panel of the present invention have electrodes which can be independently controlled, the switching of a grating electrode function between the upper and lower substrates can be achieved by switching the signal to the two substrates, thereby improving the application range of the 3D panel and the compatibility and versatility of the 3D panel. In addition, the embodiments of the present invention also disclose a method for producing the 3D panel and a 3D display apparatus having the 3D panel.
