Problems solved by technology

[0010] The disadvantages of this method are: high cost, poor realizability
Because the manufacturing process of liquid crystal is very complicated and requires a high degree of accuracy, to realize this solution, it is necessary to change the manufacturing process of liquid crystal, the investment cost is huge, and the operability is not strong.

Abstract

The invention discloses a visual angle adjustment device, which comprises a crystal layer, a control unit, and an absorption unit, wherein the crystal layer installed on the external surface of the display device is composed of acousto-optic crystal units in pre-determined matrix array and the acousto-optic crystal unit is made from acousto-optic material, and the pre-determined matrix array is corresponding to RGB matrix of the pixel of the display device; the control unit installed on one side of the crystal layer is employed to produce ultrasonic wave, control the frequency of the produced ultrasonic wave, and impose the ultrasonic wave on the crystal layer; the absorption unit installed on the other side of the layer crystal is employed to absorb the ultrasonic wave. The invention also discloses a display device and a visual angle adjustment method. This invention can adjust the visible angle of the display device conveniently and flexibly at all times and places.

Description

technical field [0001] The invention relates to display technology, in particular to a viewing angle adjusting device, a display and a viewing angle adjusting method. Background technique [0002] Wide viewing angle is one of the main parameters pursued by current display technology. For example, the current wide viewing angle liquid crystal display has a very wide viewing angle, and basically the content displayed on the liquid crystal display can be seen clearly within the range of 178 degrees. [0003] However, in some specific scenarios, the user does not want others to see the content on the display in order to protect privacy. For example, when a user uses online banking on his computer, he does not want the content on the monitor to be seen by the people next to him. [0004] In order to solve the above problems, there are currently several solutions: [0005] 1. The liquid crystal display can be rotated by the user to an angle that others cannot see. [0006] Thi...
