Embodiment 1

[0032] An embodiment of the present invention provides a display structure, the composition of the display structure, such as figure 1 As shown, including screen 1 and film body 2;

[0033] In an optional embodiment, the screen 1 is configured to project the first light 10 generated by itself to the film body 2 at a first angle.

[0034] Here, the first light 10 can be generated by the light source (such as a backlight) of the screen itself, and the first angle is within the preset incident angle threshold range; the preset angle threshold means that the light is projected to the film body, inside the film body 2 The angle at which total reflection can occur.

[0035] The film body 2 is used for receiving a first light 10 incident at a first angle and projecting a second light 20 at a second angle.

[0036] Here, the amount of light of the second light 20 is the same as that of the first light 10, and the first angle is different from the second angle; wherein, the differenc...

Embodiment 2

[0052] Based on the above Figure 1 to Figure 5 As shown in the screen and film body, Embodiment 2 of the present invention provides a display structure, and a schematic diagram of another optional composition structure of the display structure, as shown in Figure 6 As shown, including screen 1 and film body 2; where,

[0053] The screen 1 is configured to project the first light 10 generated by itself to the film body 2 at a first angle.

[0054] Here, the first angle is within a preset threshold angle of incidence; the preset angle threshold refers to an angle at which light rays are projected onto the film body and total reflection can occur inside the film body.

[0055] The screen 1 at least includes: a color filter substrate 11 and a polarizer 12 ; the size of the film body 2 is smaller than or equal to the size of the polarizer 12 . Here, the size refers to the area, that is, the area of ​​the film body 2 is smaller than or equal to the area of ​​the polarizer 12 . ...

Embodiment 3

[0068] Based on the above Figure 1 to Figure 5 As shown in the screen and film body, Embodiment 3 of the present invention provides a display structure, and a schematic diagram of another optional composition structure of the display structure, as shown in Figure 7 As shown, including screen 1 and film body 2; where,

[0069] The screen 1 is configured to project the first light 10 generated by itself to the film body 2 at a first angle.

[0070] Here, the first angle is within a preset threshold angle of incidence; the preset angle threshold refers to an angle at which light rays are projected onto the film body and total reflection can occur inside the film body.

[0071] The screen 1 at least includes: a color filter substrate 11 and a polarizer 12 ; the size of the film body 2 is smaller than or equal to the size of the polarizer 12 . Here, the size refers to the area, that is, the area of ​​the film body 2 is smaller than or equal to the area of ​​the polarizer 12 . ...

Abstract

The invention discloses a display structure, a display method and an electronic device. The display structure comprises a screen and a film body; the screen is used for projecting a first light generated itself to the film body at a first angle; the first angle is within the preset threshold value of incident angle; the film body is used for receiving the first light emitted at the first angle andprojecting a second light at a second angle; the amount of light of the second light is the same as that of the first light, and the first angle is different from the second angle.

Description

technical field [0001] The present invention relates to display technology, in particular to a display structure, method and electronic equipment. Background technique [0002] Most current electronic devices display content in a wide viewing angle mode. However, in public places, you do not want the content displayed on the electronic device to be seen by others; Display content in small viewing angle mode, that is, only the user of the electronic device can clearly see the display content in the front-facing direction, and can only see the display content with a very low contrast in other directions, or even cannot see the display content. [0003] In related technologies, users of electronic equipment usually purchase a piece of anti-peeping film by themselves, and manually paste the anti-peeping film on the outside of the display screen of the electronic equipment to realize the anti-peeping function. However, the anti-peeping film is not only costly, but also thick, an...
