Autostereoscopic display with bicylindrical lens based on temporal-spatial multiplexing
Xueling Li, and Yuanqing Wang
An autostereoscopic display system with a bicylindrical lens based on temporal-spatial multiplexing technique is introduced in this paper. The system comprises a directional scanning backlight, a liquid crystal display panel with high refreshing rate, and an eye tracking device. The directional scanning backlight consists of an LED board, two lenticular lens arrays with matching periods, a parallax barrier film, and other optical films. One of the lenticular lenses is a bicylindrical lens designed to reduce aberration, hence achieving better image quality. A prototype is set up based on the proposed structure. A series of experiments are conducted, and the overall performance of the prototype is evaluated. The LEDs are divided into 10 groups that form 10 view zones. On the one hand, it achieves full resolution in both 2D and 3D display modes. On the other hand, the viewing angle is increased to ±26 deg. Most importantly, the crosstalk is low. The minimum crosstalk is 6%, and the maximum crosstalk is 8.8% at a viewing angle of ±22 deg.

Passive patterned polymer dispersed liquid crystal transparent display
Jing Yan, Xiangwen Fan, Yifan Liu, Ying Yu, Yuming Fang, and Ruo-Zhou Li
A patterned polymer dispersed liquid crystal transparent display using one-time UV exposure is demonstrated. The device is fabricated by exposing the cell with a uniform UV light through a mask with selective attenuation of the UV light. The voltage-transmittance response of the device is different for the corresponding regions. Thus, three different states of total scattering, patterned transparent, and total transparent can be realized by controlling the applied voltages. The proposed device used in shutter mode as smart windows and in projected display mode is demonstrated, which shows great potential for smart windows with customized patterns or logos and has potential application in the field of projected transparent displays.

High-speed playback of spatiotemporal division multiplexing holographic 3D video stored in a solid-state drive using a digital micromirror device
Kohei Suzuki, Minori Tao, Yuki Maeda, Hirotaka Nakayama, Ren Noguchi, Minoru Oikawa, Yuichiro Mori, Takashi Kakue, Tomoyoshi Shimobaba, Tomoyoshi Ito, and Naoki Takada
We propose a high-speed playback method for the spatiotemporal division multiplexing electroholographic three-dimensional (3D) video stored in a solid-state drive (SSD) using a digital micromirror device. The spatiotemporal division multiplexing electroholography prevents deterioration in the reconstructed 3D video from a 3D object comprising many object points. In the proposed method, the stored data is remarkably reduced using the packing technique, and the computer-generated holograms are played back at high speed. Consequently, we successfully reconstructed a clear 3D video of a 3D object comprising approximately 1,100,000 points at 60 frames per second by reducing the reading time of the stored data from an SSD.

Immersive autostereoscopic display based on curved screen and parallax barrier
Junda Guo, Zhihui Diao, Shufeng Yan, Enqi Zhang, and Lingsheng Kong
In this Letter, we present a display system based on a curved screen and parallax barrier, which provides stereo images with a horizontal field of view of 360° without wearing any eyewear, to achieve an immersive autostereoscopic effect. The display principle and characteristics of this display system are studied theoretically in detail. Three consecutive pixels on a curved screen and parallax barrier form a display unit, which can generate separate viewing zones for the left and right eyes, respectively. Simulation and experimental results show that the non-crosstalk effect can be obtained in the viewing zones, which proves the effectiveness of this display system. This study provides some new ideas for the improvement of the autostereoscopic display and to enable envisioned applications in virtual reality technology.
