Problems solved by technology

[0003] The traditional anti-spy display is to attach an anti-spy film on the surface of the display. The anti-spy film adopts ultra-fine louver technology. The principle is similar to that of a vertical louver. The anti-spy film allows light from a specific angle of view to pass through, while light from other angles of view is blocked, causing the display to The brightness is greatly reduced

Abstract

The application provides a display panel and a control method thereof and a display device. The display panel includes a control module, a display substrate and an adjustment device arranged on the light output side of the display substrate. The adjustment device includes a first electrode, a first insulating layer, an electrostrictive layer and a second electrode, which are stacked together. Thecontrol module is connected with the first electrode and the second electrode, and is used for controlling the voltages of the first electrode and the second electrode and adjusting the electric fieldgenerated between the first electrode and the second electrode so as to deform the electrostrictive layer under the action of the electric field and adjust the propagation direction of light incidenton the electrostrictive layer. The adjustment device is arranged on the light output side of the display substrate. The electrostrictive layer in the adjustment device is deformed to form a lens structure under the action of the electric field, so as to change the propagation direction of incident light and the size of visual angle of display. Thus, the display panel achieves an anti-peep (reducing the angle of view) or sharing (increasing the angle of view) effect.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a control method thereof, and a display device. Background technique [0002] In the existing technology, mobile phones, tablet computers, TVs and other display devices mostly use wide viewing angle screens, and few manufacturers have added anti-peeping related technologies, which cannot meet the privacy needs of users, and information leakage incidents have increased frequently in recent years. With the enhancement of corporate and personal confidentiality protection awareness, there is a great market demand for the anti-peeping technology of display equipment. [0003] The traditional anti-spy display is to attach an anti-spy film on the surface of the display. The anti-spy film adopts ultra-fine louver technology. The principle is similar to that of a vertical louver. The anti-spy film allows light from a specific angle of view to pass through, while ...
