Display panel

The present invention relates to a display panel, and more particularly to a display panel having a viewing angle switching function.

At present, wide viewing angle display technology is generally divided into two categories according to its technical principle. One is to change in the alignment direction, such as vertical alignment (VA) liquid crystal panel technology, and the other is to achieve by adjusting the electric field. For example, fringe field switching (FFS) technology and in-direction switching (IPS) technology, both FFS technology and IPS technology are configured with pixel electrodes and common electrodes on the panel, and the electric field generated between the electrodes is utilized. The deflection of the liquid crystal molecules is controlled, except that the two electrodes are arranged differently, the FFS technique produces a fringing electric field, and the IPS technique produces a horizontal or transverse electric field.

In addition to the needs of the wide viewing angle display, the user sometimes does not want a third party other than himself to view the displayed content. Therefore, in order to cope with such demands, a viewer-based controllable display angle is gradually developed. Display device. The display device having the controllable viewing angle function can provide a wide viewing angle display for viewing from the side, and also allows the user to adjust the viewing angle to a narrow viewing angle to meet the confidentiality requirement.
