“…[1] Nevertheless, the existing conventional lenticular and barrier based autostereoscopy do not provide satisfying viewing experience since they suffer from reduced resolution, high crosstalk and small viewing volume. [2][3][4][5] On the contrary, the technology of directional backlight undoubtedly has unique potential for commercial application prospects with the advantages of high resolution, low crosstalk and large viewing volume. [6] Generally, the directional backlight autostereoscopy is essentially working as an optical system where the backlight, the focusing lens, and the human retina form an imaging system while the deviation of the backlight in respective to the retina will result in an intensity fluctuation felt by the human eyes.…”

Flicker is one of the most prominent issues in directional backlight autostereoscopic displays. This work studies the flicker characterization over the entire screen with a high‐speed camera. The characterization method shows that it works well to adapt with the practical visual experience and it gives a global quantitative description of the flicker. An artificial intelligent scheme with motion prediction is established to reduce the flicker, which is proved to be effective.

“…As shown in Fig. 1, the usual approach is to put a parallax barrier [19][20][21] or lenticular lens [22] as a spatial-multiplexing component. In these systems, the pixels colored as blue on the LCD will display the left eye image, and the right eye image will be loaded simultaneously by the pixels colored as red.…”

Abstract-Illumination optics in emerging naked-eye 3D display, especially in time-spatial multiplexing, or directional backlight naked-eye 3D display system, is systematically examined. Key issues in directional backlight system include: 1) Directional transmission of the left-and right-eye images to the corresponding viewing zone with small crosstalk; 2) The luminance on the screen should be homogeneous even for the viewers moving around. In this paper, we propose an adaptive optimization solution based on root mean square (RMS) for the design of illumination optics of the naked-eye 3D system. Based on the designed free-form backlight illumination, the overall design schemes for both single-user and multi-user naked-eye 3D display are proposed and demonstrated. By utilizing the novel dynamic synchronized backlight technique, the temporal crosstalk is effectively brought into control. The display defects such as the dark bands appearing at the joints of the lens array or at the middle of the Fresnel lens are simulated numerically and tested experimentally, hence providing effective design guidelines for the optical components as well as their fabrication error tolerance. Additionally, we propose a continuous backlight technique to improve the luminance homogeneity. Furthermore, a quantitative evaluation mechanism for the moiré pattern based on the Fourier analysis method, by introducing the contrast sensitivity function (CSF), is presented. A novel arrangement of a quasirandom RGB sub-pixel array is proposed to reduce the visibility of moiré pattern. As a result, full HD glassless 3D display suitable for glassless virtual and augmented realities is demonstrated with an unprecedented display quality.

“…Nevertheless, glass-assisted 3D displays are inconvenient for users and are expected to be obsolescent and replaced by auto-stereoscopic display. On the other hand, the general auto-stereoscopic techniques involving the use of parallax barrier and lenticular 3D techniques [10]- [12] are Manuscript [14]- [17] has been successful to tackle the issues related to the display resolution, homogeneity in the viewing volume. The crosstalk is also reduced to an unprecedented low level which is close to a glass-assisted stereoscopic display system, significantly increasing the possibility to adopt the backlight illumination scheme for practical applications.…”

A full resolution, low crosstalk and wide viewing angle auto-stereoscopic display is demonstrated with the use of a novel free-form surface backlight (FFSB) technique, in conjunction with a hybrid spatial and temporal control scenario. The overall crosstalk coming from adjacent channels is shown to be lower than 5% even at a wide viewing angle, and minimum achievable crosstalk can be as small as 2.41%. The key element design giving rise to achieving the full viewing angle greater than 45 degrees is also presented.
