Detailed Description
The following detailed description of embodiments of the invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
Fig. 1 is a schematic structural view of a conventional peep-proof display module reflecting peep-proof light in a shared state; fig. 2 is a schematic structural view of the conventional peep-proof display module reflecting peep-proof light in a peep-proof state. The researchers found that: as shown in fig. 1 and 2, the conventional privacy display module includes a privacy unit 10 and a module frame 20, the module frame 20 is disposed at an edge of the privacy unit 10, the module frame 20 extends to a light-emitting side of the privacy unit 10 to form a side surface 201, and the side surface 201 is perpendicular to a surface of the privacy unit 10. The peep prevention unit 10 can be switched between a peep prevention state and a sharing state. When the peeping prevention unit 10 is in the sharing state, the light angle of view of the peeping prevention unit 10 is large, and the user can reflect the light emitted by the peeping prevention unit 10 due to the large intensity of the light displayed by the peeping prevention unit 10 at the side angle, so that a white line cannot exist between the module frame 20 and the display area, as shown in fig. 1, because the side surface 201 of the module frame 20 reflects the light emitted by the peeping prevention unit 10. When the peeping prevention unit 10 is in the peeping prevention state, the peeping prevention angle 101 of the peeping prevention unit 10 is small, and since the light intensity of the peeping prevention light in the peeping prevention angle 101 in the peeping prevention unit 10 is large, and the light intensity of the light outside the peeping prevention angle 101 in the peeping prevention unit 10 is small. When the side surface 201 of the module frame 20 reflects the peeping preventing light in the peeping preventing view 101 to the region outside the peeping preventing view 101, an edge white line phenomenon occurs, that is, there is a light reflected by the module frame 20 between the module frame 20 and the display region, the picture is brighter for the display region, the contrast between the light and the display region is obvious, and the display quality is affected, as shown in fig. 2.
The problem that white lines appear at the edge of the display module is solved. The embodiment of the invention provides an anti-peeping display module, which comprises an anti-peeping unit and a module frame, wherein the module frame is arranged at the edge of the anti-peeping unit, the module frame extends to the light-emitting side of the anti-peeping unit to form a side surface exceeding the light-emitting side of the anti-peeping unit, and when the anti-peeping unit is in an anti-peeping state, the side surface avoids the anti-peeping light of the anti-peeping unit.

For example, the peep-proof viewing angle may be an area with a central brightness of more than 2% of the normal viewing angle, and the peep-proof viewing angle is 60-80 °, as shown in fig. 4.
As shown in fig. 3, the side surface 201 of the module frame 20 is an inclined surface, and an included angle between the inclined surface and the surface of the peep-proof unit 10 is smaller than 90 ° -peep-proof angle/2, so that the side surface 201 can effectively avoid the peep-proof light 102 in a peep-proof state, and the reflection of the peep-proof light 102 is avoided. The angle between the side surface 201 and the surface of the peep-proof unit 10 in the embodiment is determined by the peep-proof angle 101 of the peep-proof unit 10. For example, the peep-proof viewing angle 101 is 60 to 80 °, and the included angle between the side surface 201 and the surface of the peep-proof unit 10 is less than 50 to 60 °.
As shown in fig. 3, the privacy display module of the present embodiment further includes a transparent cover plate 30 disposed above the privacy unit 10, and an air gap 40 is formed between the transparent cover plate 30 and the privacy unit 10.

The module frame 20 includes a first frame portion 202, one end of the first frame portion 202 extends into the air gap 40, and an end surface of the first frame portion 202 on the side close to the air gap 40 forms a side surface 201.
As shown in fig. 3, the module frame 20 further includes a second frame portion 203 perpendicularly connected to the first frame portion 202, and the second frame portion 203 is located outside the edge of the peep preventing unit 10.
As shown in fig. 3, the transparent cover 30 is fixed to the first frame portion 202, the buffer 50 is provided between the transparent cover 30 and the first frame portion 202, and the buffer 50 has a buffer function to prevent the transparent cover 30 from colliding with the first frame portion 202. Wherein, the buffer 50 may be made of foam.
In some embodiments, the privacy-preserving display module can also reduce privacy-preserving light reflected by the module frame in other ways. For example, a light-shielding tape or a printed black border is attached to a display area near the module frame to shield the module frame from light.
Fig. 5 is a schematic structural view of a peep-proof unit in the peep-proof display module according to the first embodiment of the present invention. As shown in fig. 5, the privacy protecting unit 10 includes a backlight module 60, a privacy protecting film 70 disposed on the backlight module 60, and a privacy protecting liquid crystal layer 80 disposed on the privacy protecting film 70. The backlight module 60 includes a substrate 601, a light guide plate 602, a diffusion sheet 603, and a prism structure 604 stacked in sequence.
Second embodiment
The peep-proof display module of the present embodiment is substantially the same as the peep-proof display module of the first embodiment, except that the mold splitting position 204 of the module frame 20 is located at a side of the first frame portion 202 close to the peep-proof unit 10, so as to facilitate smooth demolding of the module frame 20.
In order to prevent burrs on the parting position 204 of the module frame 20 from scratching and scratching the privacy unit 10. In this embodiment, a corner formed by the side surface 201 of the module frame 20 and the bottom surface of the first frame portion 202 is provided with the scratch-proof chamfer 90.
