A three-dimensional (3D) display module, a 3D display system and a 3D display method are provided. The 3D display module includes a first plane mirror, a second plane mirror disposed correspondingly to the first plane mirror. A side of the first plane mirror coincides with a side of the second plane mirror to form a dihedral angle between the first plane mirror and the second plane mirror. The 3D display module also includes a first display screen and a second display screen disposed correspondingly to the first display screen. The first display screen and the second display screen are disposed outside the dihedral angle and at two sides of an angle bisecting plane of the dihedral angle, respectively. A first virtual image of the first display screen is overlapped with a second virtual image of the second display screen to form a first 3D virtual image.

A device is disclosed. The device includes a substrate, and a plurality of spacers arranged on one side of the substrate. Each spacer has a cross section taken in a direction parallel with the substrate, where a size of the cross section of each spacer in a length direction is greater than a size of the cross section of each spacer in a width direction. In addition, an angle between the length direction of the cross section of the spacer and an X-direction of the substrate is greater than about 0&#xb0; and less than about 90&#xb0;, or greater than about 90&#xb0; and less than about 180&#xb0;.

A liquid crystal grating module () and a two dimension-three dimension switchable liquid crystal display device using the same. The liquid crystal grating module () comprises a first transparent electrode layer () and a second transparent electrode layer (). The first transparent electrode layer () and the second transparent electrode layer () are provided with interval. The first transparent electrode layer () comprises a plurality of lateral electrode bars (). The second transparent electrode layer () comprises a plurality of vertical electrode bars (). The lateral electrode bars () and the vertical electrode bars () are alternately superposed on each other with interval to form a grating structure. The vertical electrode bars () have three different widths in the direction vertical to the liquid crystal display pixels.

A lens display device is disclosed. The device includes an optical thin film layer, a polarized switch unit, and a display unit emitting light. The optical thin film layer includes a single-refringent film layer, and first and second liquid crystal lens arrays on the single-refringent film layer. The arrays are positioned such that the lens elements of the first array are misaligned from the lens elements of the second array by half of the lens period. The polarized switch unit, when operative, polarizes the light emitting from the display unit into ordinary light entering the first liquid crystal lens array and into unordinary light entering the second liquid crystal lens array. In addition, when inoperative, the polarized switch unit polarizes the light emitting from the display unit into unordinary light entering the first liquid crystal lens array and into ordinary light entering the second liquid crystal lens array.
