In order to improve the privacy protection of personal information for electronic devices, the display devices are required to have the function of switching between wide and narrow view angle, especially in many public places. In this paper, a four-ways view angle controllable liquid crystal display technique is investigated with a specially designed pixel by dividing a sub-pixel into two domains, which realizes the wide and four-ways narrow view angle switchable with a single liquid crystal alignment direction. The display device described in this paper includes a view angle controllable electrode in the top substrate, the pixel and common electrodes are placed in the bottom substrate. When the view angle controllable electrode is set as common voltage, the fringe field is formed between pixel and common electrodes make the liquid crystal rotate horizontally toward different directions, so the wide view angle mode is realized. When the alternating voltage is applied to the view angle controllable electrode, the liquid crystal molecules rotate and have a large tilted angle under the action of horizontal and vertical electric fields, the liquid crystal molecules have a large phase delay at off-axis direction, and induce the light leakage in the dark state, so the four-ways narrow view angle effect is achieved. The experiment results show that the wide view angle can reach more than 60° in vertical and horizontal direction and the pictures are clearly visible. In the narrow view angle mode, it is perfect blocked in the view angle at 60° of polar angle in vertical direction and 45° in horizontal direction. The technical structure is simple, without any extra components, and the four-ways view angle switchable structure can be realized with one liquid crystal cell and one backlight.
