Abstract: This paper presents a dynamic single-pixel dynamic liquid crystal lens and uses it for three-dimensional display technology. With this structure and the corresponding driving method, the autostereoscopic display system can achieve high resolution and low crosstalk, thereby improving the autostereoscopic display performance. In this paper, the influence of the divergence angle of the light source on the crosstalk of single-pixel stereo display technology is discussed.
1 Introduction
Recently, 3D display technology has received great attention and is likely to bring a considerable market in the future. The three-dimensional display is divided into various types according to the implementation method, for example, a polarized glasses method, a helmet type, a barrier type, a prism type, a body three-dimensional shape, a holographic three-dimensional shape and the like. At present, stereoscopic display technology still has many problems, such as low resolution, large crosstalk, and uniformity to be improved. It is precisely because of these problems that stereoscopic 3D displays have not yet been widely promoted.
Among the three-dimensional display, the liquid crystal lens technology is widely used. The main reason is that it has high flexibility. It only needs to control the voltage distribution of the corresponding electrode in the liquid crystal layer, and the refractive index distribution of the liquid crystal lens will change accordingly. Thus, the distribution of the light emitted by the pixel is controlled, and most of the 2D/3D conversion is realized by using a liquid crystal lens. The basic principle of the three-dimensional display realized by the conventional liquid crystal lens is to change the voltage distribution on the electrode of the liquid crystal layer, so that the distribution of the refractive index is similar to the distribution of the solid lens, and control the distribution of the light emitted by a group of pixels, thereby achieving a three-dimensional effect. The disadvantage is that the cell thickness of the liquid crystal lens is large, which may cause a manufacturing process problem and seriously affect the switching speed; at the same time, it still causes a decrease in the resolution of the display.
In this paper, we propose a way to form a separate liquid crystal lens on a single pixel, as shown in Figure 1. By dynamically driving the electrodes of the liquid crystal layer, all the rays emitted by all the screen pixels point to the same field of view at a certain time (for example, field of view 1), and point to another field of view (for example, field of view N) at the next time, so that The use of timing signals enables three-dimensional display without reducing spatial resolution.
The three-dimensional stereoscopic display method based on single pixel lens proposed in this paper can solve the problem of resolution reduction brought by the traditional method. Since a liquid crystal lens controls the light of one pixel, more precise control can be realized, thereby improving the crosstalk and uniformity of the 3D display.
