Lens, display device and display processing method of display device

Abstract

The embodiments of the present invention disclose a lens, a display device and a display processing method of the display device. The display device includes a display device layer, at least one lens,and a control module, wherein the display device layer is provided with a plurality of light emitting units, and the control module is connected with each lens; a light emitting unit is disposed at the light entering side of each lens; the control module is used for applying control signals to the lenses; the lenses correspondingly deform according to the control signals, the focal lengths of thedeformed lenses decrease or increase, so that the relative positions of the light-emitting units at the light entering sides of the lenses and the focal lengths of the corresponding lenses change; and light emitted by the light-emitting units passes through the lenses so as to form parallel or scattered light. With the lens, the display device and the display processing method of the display device provided by the embodiments of the present invention adopted, problems such as the problem of the sharp decrease of the brightness of an existing peep-proof display device and the problem of the increase of hardware cost and production difficulty of products which are caused by adding a peep-proof device for blocking light so as to realize a narrow viewing angle can be solved.

Description

technical field [0001] The present application relates to but not limited to the field of display technology, especially a lens, a display device and a display processing method of the display device. Background technique [0002] With the development of the display technology field, displays have been widely used in various aspects of people's daily life, and users have higher and higher functional requirements for displays, for example, users have different requirements for viewing angles of displays in different applications. [0003] When the user is in an environment that requires sharing, such as watching a program with others, the display needs to have a wider viewing angle to achieve the purpose of sharing; and when the user is in an open environment that requires privacy, such as the user passes When the display enters various online payment passwords, and when viewing private or confidential information in a public environment, the display needs to have a narrow vi...
