However, as will be understood by those skilled in the art, the present invention may be practiced without these specific details.
Example 1:
as shown in fig. 1 to 6, wherein fig. 4 to 6 are schematic sectional views along a-a of fig. 3. The present embodiment provides a peep-proof structure, including:
peep-proof layer 1, including a plurality of light-transmitting portions 11 and a plurality of opaque portion 12, every light-transmitting portion 11 and opaque portion 12 all are cyclic annularly, all light-transmitting portions 11 and opaque portion 12 distribute concentrically, and distribute an opaque portion 12 between arbitrary two adjacent light-transmitting portions 11, the light of shooting to first surface 13 of peep-proof layer 1 can see through light-transmitting portion 11, and can not see through opaque portion 12 to make at least some light follow second surface 14 of peep-proof layer 1 with predetermineeing the angle and shoot out.
In which, that is, the privacy layer 1 is formed by the light-transmitting portion 11 and the light-non-transmitting portion 12, and the light-transmitting portion 11 and the light-non-transmitting portion 12 are separately divided, for example, as shown in fig. 3, the light-non-transmitting portion 12, the light-transmitting portion 11, the light-non-transmitting portion 12, and the like (similar to an annular grating structure) are sequentially arranged from the center of the privacy layer 1 to the outside, so that the first surface 13 and the second surface 14 of the privacy layer 1 are respectively formed by a plurality of rings.
When light is directed to the first surface 13 of the privacy layer 1, the light directed to the transparent portion 11 is transmitted through the transparent portion 11, and the light directed to the opaque portion 12 is absorbed by the opaque portion 12, wherein the light first transmitted through the transparent portion 11 and then directed to the opaque portion 12 is also absorbed by the opaque portion 12. This allows a portion of the light directed to the first surface 13 to be absorbed by the opaque portion 12, another portion of the light to pass through the privacy layer 1, and the light passing through the privacy layer 1 to emerge from the second surface 14 at a predetermined angle, i.e., the light passing through the privacy layer 1 is at an angle to the second surface 14, as shown by the arrows in fig. 4-6, wherein the arrows in fig. 4-6 indicate the light passing through the privacy layer 1. When human eyes are located within the range of the preset angle, the light emitted from the second surface 14 of the peep-proof layer 1 can be seen, and when the human eyes are no longer within the range of the preset angle, the light emitted from the second surface 14 of the peep-proof layer 1 can not be seen, so that the peep-proof effect is achieved.
As shown in fig. 1, the light-transmitting portion (the non-shaded portion in fig. 1) and the light-proof portion (the shaded portion in fig. 1) of a peep-proof structure in the prior art are respectively in a strip shape, so that the peep-proof structure in the prior art can only perform a peep-proof function on two sides (as shown by arrows in fig. 1) parallel to the light-transmitting portion or the light-proof portion, and cannot perform a peep-proof function on the other directions. In the peep-proof structure of the present embodiment, since the opaque portion 12 is in a concentric ring shape, the light emitted to the opaque portion in each direction can be emitted from the second surface 14 of the peep-proof layer 1 at a predetermined angle, that is, the light emitted from the second surface 14 is in a state of converging from a divergent state to the center of the peep-proof layer 1. The event is for prior art's peep-proof structure, the peep-proof structure of this embodiment can play the peep-proof effect (360 peeps) to all directions to this peep-proof structure's peep-proof effect is better, and then improves the display device peep-proof performance that utilizes this peep-proof structure to form.
Preferably, the light-transmitting portion 11 and the light-opaque portion 12 are each circular or elliptical rings.
Wherein, that is to say, each of the light-transmitting portion 11 and the light-non-transmitting portion 12 has a similar annular shape. Meanwhile, each of the light-transmitting portions 11 and the light-opaque portions 12 may have an annular shape, which may be adjusted according to actual needs. The privacy range of privacy layer 1 can be adjusted by changing the shape of light-transmitting portions 11 and light-opaque portions 12.
When each of the light-transmitting portions 11 and the non-light-transmitting portions is a regular circular ring or an elliptical ring, the peeping prevention range of the peeping prevention layer 1 can be relatively regular, the manufacturing process of the peeping prevention layer 1 can be simple and convenient, and the manufacturing cost can be reduced.
Preferably, in a plane parallel to the privacy layer 1, the size of the light-transmitting portion 11 near the center of the privacy layer 1 is larger than the size of the light-transmitting portion 11 away from the center of the privacy layer 1.
As shown in fig. 3, the larger the size of the light-transmitting portion 11 in a plane parallel to the privacy layer 1, the larger the range of light emitted from the second surface 14, that is, the smaller the privacy range. Since a user of the ordinary peep-proof layer 1 is almost facing the peep-proof layer 1, the peep-proof requirement for the peep-proof layer 1 close to the center is smaller than the peep-proof requirement for the peep-proof layer 1 far from the center, so that the peep-proof capability of the peep-proof layer 1 close to the center can be smaller than the peep-proof capability far from the center, that is, the size of the light-transmitting portion 11 close to the center of the peep-proof layer 1 is larger than the size far from the center of the peep-proof layer 1.
The arrangement of the above-mentioned structure of the light-transmitting portion 11 can ensure the normal use of the device by the user of the device having the peep-proof layer 1 on the premise of ensuring the peep-proof effect of the peep-proof layer 1, and can reduce the absorption of the light-proof portion 12 of the peep-proof layer 1 to light, thereby ensuring the amount of light penetrating through the peep-proof layer 1, and further ensuring the display brightness of the device having the peep-proof layer 1.
Preferably, a case of the present embodiment is that the cross section of the light-transmitting portion 11 in a specific plane is a rectangle, and the specific plane is a plane perpendicular to the privacy layer 1 and parallel to the radial direction of the light-transmitting portion 11.
Here, as shown in fig. 4, that is, when the section of the light-transmitting portion 11 in a specific plane is rectangular, the section of the light-impermeable portion 12 located between the two light-transmitting portions 11 in the specific plane is also rectangular.
Preferably, another case of the present embodiment is that the cross section of the light-transmitting portion 11 in a specific plane is a trapezoid, and the specific plane is a plane perpendicular to the privacy layer 1 and parallel to the radial direction of the light-transmitting portion 11.
Here, as shown in fig. 5 and 6, that is, when the cross section of the light-transmitting portions 11 in a specific plane is a trapezoid, the cross section of the light-non-transmitting portion 12 located between two light-transmitting portions 11 in a specific plane is a trapezoid in the opposite direction.
Specifically, the base of the trapezoid on the first surface 13 is larger than the base of the trapezoid on the second surface 14, or the base of the trapezoid on the first surface 13 is smaller than the base of the trapezoid on the second surface 14.
In other words, the section of the light-transmitting portion 11 perpendicular to the privacy layer 1 is a trapezoid, and the side of the trapezoid on the first surface 13 is larger than the side of the trapezoid on the second surface 14; another is that the sides of the trapezoid at the first surface 13 are smaller than the sides at the second surface 14.
By changing the shape of the cross section of the light transmitting portion 11 in a specific plane, the range of light exiting the second surface 14 of the privacy layer 1 can be adjusted. Specifically, as shown in fig. 5, when the section of the light-transmitting portion 11 in a specific plane is a trapezoid, and the side of the trapezoid on the first surface 13 is larger than the side on the second surface 14, the peep-proof effect of the peep-proof layer 1 is the best; as shown in fig. 4, when the section of the light-transmitting portion 11 in a specific plane is rectangular, the privacy effect of such privacy layer 1 is inferior; as shown in fig. 6, when the section of the light-transmitting portion 11 in a specific plane is a trapezoid whose side located at the first surface 13 is smaller than that located at the second surface 14, the peep-proof effect of such a peep-proof layer 1 is at best poor. In the practical application process of the privacy layer 1, the shape of the cross section of the light-transmitting portion 11 in a specific plane may be determined according to the requirements of the actual situation.
The shape of the cross section of the light transmitting portion 11 in a specific plane may be any other suitable shape, and is not limited to the above shape.
In the privacy layer 1 of the present embodiment, the privacy effect of the privacy layer 1 can be adjusted by only changing the shape of the cross section of the light-transmitting portion 11 in the specific plane, which is not only simple to prepare, but also can expand the application range of the privacy layer 1.

Specifically, the first transparent protective layer 4 and the second transparent protective layer 5 may be formed of a polyethylene terephthalate (PET) material, or may be formed of other suitable materials.
