Dual-view integral imaging display using a polarizer.

We propose a dual-view integral imaging display using a polarizer. It consists of a display panel, a polarizer, a microlens array, and two pairs of polarizer glasses. The polarizer comprises the left and right subpolarizers whose polarization directions are orthogonal. Two kinds of elemental images are captured from different three-dimensional scenes and located on the left and right half of the display panel. The lights emitting from two kinds of elemental images are polarized by the left and right subpolarizers. The polarization directions of the two pairs of polarizer glasses used in the left and right viewing zones are the same as those of the right and left subpolarizers, respectively. Two different three-dimensional images are simultaneously viewed in the left and right viewing directions by wearing two pairs of polarizer glasses. A prototype of the proposed dual-view integral imaging display is developed, and the experimental results verify the hypothesis.

Dual-view integral imaging three-dimensional display using polarized glasses.

We propose a dual-view integral imaging (DVII) three-dimensional (3D) display using polarized glasses. The DVII 3D display consists of a display panel, a polarized parallax barrier, a microlens array, and two pairs of polarized glasses. Two kinds of elemental images, which are captured from two different 3D scenes, are alternately arranged on the display panel. The polarized parallax barrier is attached to the display panel and composed of two kinds of units that are also alternately arranged. The polarization directions between adjacent units are perpendicular. The polarization directions of the two pairs of polarized glasses are the same as those of the two kinds of units of the polarized parallax barrier, respectively. The lights emitted from the two kinds of elemental images are modulated by the corresponding polarizer units and microlenses, respectively. Two different 3D images are reconstructed in the viewing zone and separated by using two pairs of polarized glasses. A prototype of the DVII 3D display is developed and two 3D images can be presented simultaneously, verifying the hypothesis.

Autostereoscopic 3D display with high brightness and low crosstalk.

An autostereoscopic 3D display with high brightness and low crosstalk is proposed. This display consists of a liquid crystal display (LCD) panel, a reflective light source (RLS), and a parallax barrier or lenticular lens. The RLS behind the LCD panel consists of a light source, a light guide plate, and a reflection cavity. The RLS can make light reflect continuously in the reflection cavity and exit from the slits on the cavity surface. The widths of these slits are narrower than those of the subpixels, so they can provide a low aperture ratio, which is helpful in obtaining low crosstalk. Because of the reflection cavity, the optical efficiency is higher than that using a single barrier. The parallax barrier or lenticular lens can project parallax images on the LCD panel into different directions. Then 3D images are formed. A prototype of the proposed 3D display having high brightness 3D images and low crosstalk is developed. The experimental results agree well with the theory.

Reflected-light-source-based three-dimensional display with high brightness.

A reflected-light-source (RLS)-based 3D display is proposed. This display consists of an RLS and a 2D display panel. The 2D display panel is located in front of the RLS. The RLS consists of a light source, a light guide plate (LGP), and a reflection cavity. The light source and the LGP are located in the reflection cavity. Light from the light source can enter into the LGP and reflect continuously in the reflection cavity. The reflection cavity has a series of slits, and light can exit only from these slits. These slits can work as a postpositional parallax barrier, so when they modulate the parallax images on the 2D display, 3D images are formed. Different from the conventional 3D display based on a parallax barrier, this RLS has less optical loss, so it can provide higher brightness. A prototype of this display is developed. Experimental results show that this RLS-based 3D display can provide higher brightness than the conventional one.

Orthogonal-polarized directional backlight-based three-dimensional display with high horizontal resolution and low crosstalk.

An orthogonal-polarized directional backlight-based three-dimensional (3D) display is proposed. This backlight consists of an orthogonal-polarized backlight and a parallax barrier, so it can project light with different polarized directions to different spatial directions. The backlight can project the pixels with different polarized directions on the two-dimensional display in different directions and form 3D images. With this backlight, the proposed display can provide double horizontal resolution. A prototype of this display is developed. Experiment results show that this display with double horizontal resolution can provide a better display effect than the conventional one, and it can decrease crosstalk to a low level.

3D display based on parallax barrier with multiview zones.

A 3D display based on a parallax barrier with multiview zones is proposed. This display consists of a 2D display panel and a parallax barrier. The basic element of the parallax barrier has three narrow slits. They can show three columns of subpixels on the 2D display panel and form 3D pixels. The parallax barrier can provide multiview zones. In these multiview zones, the proposed 3D display can use a small number of views to achieve a high density of views. Therefore, the distance between views is the same as the conventional ones with more views. Considering the proposed display has fewer views, which bring more 3D pixels in the 3D images, the resolution and brightness will be higher than the conventional ones. A 12-view prototype of the proposed 3D display is developed, and it provides the same density of views as a conventional one with 28 views. Experimental results show the proposed display has higher resolution and brightness than the conventional one. The cross talk is also limited at a low level.

Special subpixel arrangement-based 3D display with high horizontal resolution.

A special subpixel arrangement-based 3D display is proposed. This display consists of a 2D display panel and a parallax barrier. On the 2D display panel, subpixels have a special arrangement, so they can redefine the formation of color pixels. This subpixel arrangement can bring about triple horizontal resolution for a conventional 2D display panel. Therefore, when these pixels are modulated by the parallax barrier, the 3D images formed also have triple horizontal resolution. A prototype of this display is developed. Experimental results show that this display with triple horizontal resolution can produce a better display effect than the conventional one.

Three-dimensional display based on dual parallax barriers with uniform resolution.

The 3D display based on a parallax barrier is a low-cost autostereoscopic display. However, the vertical and horizontal resolution of the 3D images displayed on it will be seriously nonuniform as this display has a large number of views. It will worsen the display quality; therefore, a 3D display that consists of a 2D display panel and dual parallax barriers is proposed. With a 2D display panel, the proposed 3D display provides the synthetic images with square pixel units in which the arrangement of pixels can make the 3D image have uniform resolution. With the dual parallax barriers, the proposed 3D display shows the pixels in square pixel units for different horizontal views. Therefore, this display has uniform resolution of 3D images. A four-view prototype of the proposed 3D display is developed, and it provides uniform 3D resolution in the vertical and horizontal directions.
