Display panel, control method thereof and display device

The invention discloses a display panel, a control method thereof and a display device. The display panel comprises a display function layer and a visual angle control layer located on the light emitting side of the display function layer. The visual angle control layer comprises a first electrode, a second electrode and a liquid crystal layer, the liquid crystal layer is located between the first electrode and the second electrode, at least partial areas in the first electrode and the second electrode are graphical hollow areas, and the first electrode and the second electrode are used for controlling the deflection direction and angle of liquid crystal molecules in the liquid crystal layer. The deflection degrees of the liquid crystal molecules corresponding to the hollowed-out areas and the non-hollowed-out areas in the first electrode and the second electrode are different. According to the technical scheme of the embodiment of the invention, the peep-proof effect can be improved. 本发明公开了一种显示面板及其控制方法和显示装置。
