Display device for controlling display angle and manufacturing method thereof

Abstract

The invention provides a display device for controlling a display angle and a manufacturing method thereof. The display device comprises a pixel unit array composed of a plurality of pixel units, wherein each pixel unit comprises a sub-pixel unit array composed of sub-pixel units capable of emitting light with different colors; each sub-pixel unit comprises a sub-pixel layer for emitting light with pre-set color corresponding to the sub-pixel unit and a light refraction layer arranged above the sub-pixel layer and composed of a micro-nano structure array; and each micro-nano structure array in the light refraction layers has the equivalent refraction rate aiming at the light with the pre-set color, and the light with the pre-set color, which is emitted from the sub-pixel layers, is refracted b the light refraction layers. By virtue of the display device and the manufacturing method thereof, provided by the invention, the display angle can be changed, and the problems that the resolution ratio of the display device is reduced and the display brightness is not uniform can be effectively avoided.

Description

technical field [0001] The present invention generally relates to a display device, and more particularly, to a display device capable of controlling a display angle and a manufacturing method thereof. Background technique [0002] The display angles of the screens of existing electronic devices (such as smart phones, notebook computers, tablet computers, desktop computers, game consoles, personal digital terminals, and game consoles) are generally relatively large (the maximum display angle of a general screen can reach 120 degrees. ~140 degrees), this is because the light emitted by each pixel of the screen is scattered forward. Therefore, when a user checks the displayed content on the screen of the electronic device, other people located on both sides of the user may also peek at the displayed content on the screen from the side, which is not conducive to the privacy protection of the user. [0003] In the prior art, in order to prevent other people from peeking at the ...

AI Technical Summary

Problems solved by technology

[0005] 1. Attach a layer of anti-peeping film on the top of the screen of the electronic device. At this time, the blades of the louvers will block the pixels on the screen. Therefore, this method will lead to uneven display brightness of the screen

[0006] 2. The anti-peeping film is integrated with the screen of the electronic device for production. At this time, the blades of the louvers are set between pixels. Therefore, the blades of the louvers will occupy the area of ​​​​the pixels in this way, resulting in a decrease in the resolution of the screen.

[0007] In addition, although the above two methods can reduce the display angle of the screen, they cannot adjust the display angle, and cannot meet the requirements when a large display angle is required
