Abstract

The invention discloses a display device. The display device comprises a display screen and an optical diffraction film arranged on the display screen, the optical diffraction film comprises an optical diffraction device for changing the viewing angle of the display screen. The optical diffraction device is arranged with different patterns on the upper surface of the optical diffraction film, thedirection of light transmission can be changed, and thus the viewing angle of the display screen can be changed. Compared with an existing way of changing the viewing angle of a liquid crystal displaythrough display devices and polaroids, the display device takes the liquid crystal display as a surface light source, the optical diffraction film is adhered to the upper surface of the surface lightsource, through the optical diffraction device of the optical diffraction film with different patterns, the purpose of changing the viewing angle of the display screen can be achieved, the complexityof the production process is simplified, and meanwhile, the production cost is reduced.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly to a display device. Background technique [0002] Existing liquid crystal display screens are widely used in life and work, and require different viewing angles due to different requirements. For example, when a laptop is used in public, a small viewing angle is required to prevent peeping, and when many people in a family use a laptop to watch videos, the LCD screen of the laptop needs to have a larger viewing angle to facilitate multiple people to use. [0003] Based on this requirement, in the prior art, the viewing angle of the liquid crystal display is usually changed through display devices and polarizers. However, this will increase the complexity of the manufacturing process and increase the cost. Contents of the invention [0004] In order to solve the disadvantages of the prior art, the present invention provides a display device. [0005] The technic...
