Abstract

The invention provides a peep-proof panel, a display device and a control method of the peep-proof panel, and relates to the technical field of display, and when the peep-proof panel is applied to the display device, peep prevention in the horizontal direction and the vertical direction can be achieved at the same time. The peep-proof panel comprises a first substrate, a second substrate and a liquid crystal layer, the first substrate comprises a first substrate and a first polarization unit; the second substrate comprises a second substrate and a second polarization unit; the transmission axis of the first polarization unit is parallel to the transmission axis of the second polarization unit; the included angle between the transmission axis of the first polarization unit and the first substrate is a first included angle, the included angle between the transmission axis of the second polarization unit and the second substrate is a second included angle, and the first included angle and the second included angle are the same and are acute angles; the liquid crystal layer is configured to be capable of changing the polarization direction of light rays emitted to the second substrate in the peep-proof state and not changing the polarization direction of the light rays emitted to the second substrate in the non-peep-proof state. The method is suitable for manufacturing the peep-proof panel.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an anti-peeping panel, a display device and a control method thereof. Background technique [0002] With the development of technology, the anti-peep function is applied to various display devices, such as bank cash machines, high-end anti-peep notebooks, etc., to prevent information leakage. [0003] However, the current display devices with anti-peeping function can only realize anti-peeping in the horizontal direction, and the display device cannot prevent peeping in the vertical direction, resulting in poor anti-peeping effect. Contents of the invention [0004] Embodiments of the present invention provide an anti-peeping panel, a display device and a control method thereof. When the anti-peeping panel is applied to a display device, the display device can realize anti-peeping in the horizontal direction and vertical direction at the same time, thereby improving th...
