A 2D/3D compatible display is proposed. The proposed 2D/3D compatible display can make viewers freely choose to view 2D or 3D images, and do not interact with each other. The proposed 2D/3D compatible display consists of a 2D display panel, a polarization modulator, and a pair of polarizing glasses. The 2D display panel is used to display a 2D synthetic image. The 2D synthetic image can be used to show the first parallax image. The polarization modulator can change the polarization directions of 2D synthetic image. Therefore, the component of the 2D synthetic image on specific polarization direction can be used to show the second parallax image. The polarizing glasses have only one lens covered with polarizer. This lens is used to view the second parallax image. And another lens without polarizer is used to view the first parallax image included in the original 2D synthetic image. Therefore, 3D image is displayed. A prototype of the proposed display is developed. Experimental results agree well with the theory. We believe it will be a potential application in 2D/3D compatible display.

We propose a crosstalk-free integral imaging three-dimensional (3D) display using a pinhole array. It consists of a back light unit, a pinhole array and a liquid crystal panel. The pinhole array, which is attached to the back light unit, is located between the back light unit and the liquid crystal panel. Three imaging models of the integral imaging 3D display with different pinhole arrays are analyzed to reveal the relationship between the aperture width of the pinhole array and the crosstalk. The optimal value of the aperture width of the pinhole array is also obtained to eliminate the crosstalk. A prototype using the optimal pinhole array is developed, and the experiment results agree well with the theory.

A dual-view one-dimensional integral imaging (DV1DII) display with large viewing angle is proposed. It is composed of a display panel, a polarizer, a lenticular lens array and two pairs of polarized glasses. The elemental images 1 and 2, which are captured from the 3D scenes 1 and 2, are respectively displayed on the left and right half of the display panel. The lights emitted from the elemental images 1 are sequentially polarized and modulated by the sub-polarizer 1 and the corresponding lenticular lenses. The orthoscopic 3D image 1 is observed in the right viewing direction by wearing the polarized glasses 1. In a similar way, the orthoscopic 3D image 2 is seen in the left viewing direction by wearing the polarized glasses 2. A prototype of the proposed DV1DII display is developed, and good experimental results agree well with the theory.

We propose a dual-view one-dimensional integral imaging 3D display using a barrier array. It is composed of an organic light emitting diode (OLED), a barrier array and a liquid crystal panel. The OLED and the liquid crystal panel are used to present an element image array and a parallax barrier. The barrier is located at the middle of adjacent slits. The gap between adjacent barriers is equal to the pitch of the slit. The element image array consists of the left and right elemental images which are alternately arranged. The left and right elemental images located between adjacent barriers are only modulated by the corresponding slit between those. A prototype is developed, and the viewing ranges of the left and right viewing zones are increased along with the increase of the viewing distance.

Retro-reflection based projection 3D display with low crosstalk is proposed. The 3D display consists of a retro-reflective sheet, an image projector array, a vertical scattering layer, and two optical noise sources projectors. The image projector array is used to provide parallax images. The retro-reflective sheet is used to reflect parallax images to different horizontal viewpoints to form 3D images. The vertical scattering layer is used to scatter the reflected light in the vertical directions, and form viewing areas in the vertical projection area of each corresponding projector. The optical noise source projector provides salt and pepper noise to reduce crosstalk. A prototype of the proposed 3D display is developed, and the experiment results agree well with the theory.

We propose a tri-view integral imaging (TVII) three-dimensional (3D) display which presents three different 3D images in the left, middle and right viewing directions simultaneously. The element image array (EIA) of the TVII 3D display consists of three sub-EIAs. The three sub-EIAs captured from three different scenes are responsible for three different 3D images in the left-, middle- and right-view, respectively. A prototype of the TVII display is developed, and the experimental results verify the correctness of the theory. The TVII 3D display is easily convertible to mono-view or dual-view II 3D display.

A parameter design of a parallax barrier is one of the most important keys to design a one-dimensional integral imaging (1DII) display using parallax barrier. The relationship between the thickness of the parallax barrier and the viewing angle of the 1DII display is studied, and the maximal value of the thickness is also obtained. When the thickness of the parallax barrier is greater than the maximal value, the viewing angle of the 1DII display is decreased with increasing the thickness of the parallax barrier. A prototype of the 1DII display using parallax barrier is developed, and the experimental results agree well with the theory.

The parallax barrier 3D display is an autostereoscopic display with low cost. However, the conventional parallax barrier 3D display has a disadvantage of low brightness. Therefore, a parallax barrier 3D display based on shared pixels is proposed. The shared pixels have adapted pixel values which limit crosstalk in a low level, so that they can be displayed simultaneously in both two parallax images. These pixels increase aperture ratio of the parallax barrier. Therefore, they can bring high brightness. A prototype of the proposed 3D display is developed and it has higher brightness than those based on the conventional one.

A one-dimensional integral imaging (1DII) display with large viewing angle is proposed in this paper. The proposed 1DII display is composed of a display panel, a barrier array and a parallax barrier. The barriers, which are located at the junction of adjacent elemental images on the display panel, are perpendicular to the display panel and the parallax barrier. It is different from the previous 1DII display using the barrier array that the aperture centers of the slits aren’t aligned with the centers of the corresponding element images. Moreover, the most important difference is that the pitch of the slit is small than that of the elemental image. The widths of all viewing zones reconstructed by elemental images are identical at the optimal viewing distance. Thus, the viewing angle of the proposed 1DII display isn’t affected by the number of the slits and the elemental images. A prototype of the proposed 1DII display is developed, and good experimental results are obtained.
