Holographic 3D display is a true 3D display technology, which can provide realistic 3D images without any special eyewear for observers. It will be ultimately developed into holographic 3D TV. However, dynamic holography has not been applied in 3D video display because of limitations of current holographic display devices-spatial light modulators and slow-response dynamic holographic materials with hologram refresh rate, less than 25 Hz. Recently, we achieved real-time dynamic holographic 3D display in a super-fast response liquid crystal films. The hologram formation time and self-erasable time can both reach ~ 1 ms in the films. Holographic 3D video display with refresh rate, at least 60Hz,was realized using it without any cross talk. Moreover, any SLMs or other holographic display devices resulting from these materials need not to be pixilated. It is easier to fabricate large-size color video-rate holographic 3D displays by using these materials. We have designed holographic 3D video display systems and are trying to build a holographic 3D TV using the liquid crystal screen. This paper will focus on holographic 3D video display of liquid crystal films, and present their potential applications in a large-size, high-definition, and color holographic 3D video display-holographic 3D TV.

Viewing depth is usually limited in integral imaging system and must be improved for practical applications. A proposed way of image reconstruction with depth enhancement via sequential double lens arrays is investigated and demonstrated in this study.

The time-multiplexed system is an excellent choice when considering full-resolution three-dimension(3D) images and 2D/3D switchable functionality. However, the current directional sequential backlight system can allow only one observer at a time to watch the 3D image. Under the circumstances, we proposed multi-user 3D film to increase the number of observers. Not only it can increase the observer from one to three, but also easy to carry and simple to align.

This system was basically a camera-based system and overcome the issue of inactive region in near field by using direct-flective sensors. Finally, the concept was verified on a virtual 8-inch display. The maximum working range and the mean error in near field is 50 cm and 1.2 cm.

Traditional color mapping is using red, green, and blue three channels independently for adjustment on device. However, it will make some errors. In this paper, we use RGB without independence for color mapping. Finally, realizing it on FPGA and using a movie to demonstrate by changing specific color with other colors unchanged.
