All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "first," "second," "third," "fourth," and the like in the description and in the claims, as well as in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
As shown in fig. 1, the present embodiment provides a privacy film 100, where the privacy film 100 includes:
the driving layer 101 and the retaining wall structures 102, and a plurality of retaining wall structures 102 are arranged on the driving layer 101.
In the embodiment of the invention, when the privacy film 100 is applied, that is, when the privacy film is attached to the display screen, a voltage is applied to the driving layer 101, and the privacy film 100 can change the viewing angle of the display screen. It should be noted that the magnitude and the electrical property of the applied voltage both have an influence on the viewing angle of the display screen changed by the privacy film 100.
The barrier structure 102 is a transparent cavity, and the transparent cavity is filled with a transparent filling liquid 1021 and non-transparent particles 1022, and the non-transparent particles 1022 carry charges of the same polarity.
In an embodiment of the present invention, the transparent filling liquid 1021 may be a transparent and non-corrosive solution, which is not limited herein. In the embodiment of the present invention, the non-transparent particles may be pure black particles, white particles, or mixed colors, and may be made of other materials as long as they are non-transparent and chargeable particles, and the material is not limited herein. The shape of the opaque particles 1022 may be spherical or cubic, and is not limited herein, as long as the particles are sufficiently small and can flow in the transparent filling liquid 1021. The material of the non-transparent particles 1022 may be a charged metal, or may be other materials capable of carrying charges, and is not limited herein. It is common knowledge to charge the non-transparent particles 1022, and the detailed description thereof is omitted here.
In the embodiment of the present invention, the retaining wall structure 102 determines the size of the viewing angle of the display screen changed by the peep-proof film 100. In some possible embodiments, when the privacy film 100 is attached to a display panel, a wall structure 102 is beside a pixel of the display panel, and typically, the wall structure 102 is vertically disposed on the driving layer 101, although the wall structure 102 may also be obliquely disposed on the driving layer 101. The retaining wall structure 102 is filled with transparent filling liquid 1021 and non-transparent particles 1022, and the non-transparent particles 1022 can be distributed in a changed manner under the driving of the driving layer 101.
Specifically, when the driving layer 101 is not applied with voltage, the non-transparent particles 1022 are retained at the bottom of the retaining wall structures 102 close to the driving layer 101, and when the driving layer 101 is applied with voltage, the distribution of the non-transparent particles 1022 is changed, for example, the non-transparent particles 1022 are driven to the middle, top or uniformly distributed on the retaining wall structures 102 of the retaining wall structures 102, so as to block some angles of the display screen, thereby achieving the anti-peeping effect.
In the embodiment of the present invention, a plurality of wall structures 102 are disposed on one side of the driving layer 101, and the distribution of the non-transparent particles 1022 in the wall structures 102 can be driven by the driving layer 101. Specifically, when the driving layer 101 is applied with a voltage, the distribution of the non-transparent particles 1022 in the retaining wall structure 102 is directly affected, so as to determine the size of the viewing angle of the privacy film 100. Since the voltage applied to the driving layer 101 can flexibly control the distribution of the non-transparent particles 1022 in the retaining wall structure 102, the viewing angle of the privacy film 100 can also be flexibly controlled. It should be noted that the retaining wall structure 102 generally needs to be plural, and preferably, when it is applied, it is exactly distributed in the non-pixel area of the display screen, i.e. the pixel black area, so that it will not block any pixel in the wide-angle mode, and can control the angle well in the narrow-angle mode. In other possible embodiments, the retaining wall structures 102 may be disposed only in the longitudinal pixel black area stripes, or the retaining wall structures 102 may be disposed only in the transverse pixel black area stripes, or the arrangement distribution of the retaining wall structures may be set according to other requirements, which is not limited herein.
The driving layer 101 includes a transparent carrier 1011 and a circuit layer 1012, the circuit layer 1012 is disposed inside the transparent carrier 1011, and when the circuit layer 1012 is applied with a voltage, the distribution of the non-transparent particles 1022 in the retaining wall structure 102 is changed.
In the embodiment of the present invention, the driving layer 101 is composed of a transparent carrier 1011 and a circuit layer 1012. The material of the transparent carrier 1011 may be Polyethylene terephthalate (abbreviated as PET), or glass, as long as it is electrically nonconductive and transparent, and is not limited herein. The circuit layer 1012 is made of a conductor, which may be a metal or other non-metallic conductor material, and is not limited herein.
The circuit layer 1012 is disposed inside the transparent carrier 1011, the circuit layer 1012 is disposed inside the transparent carrier, and when the circuit layer 1012 is applied with a voltage, the distribution of the non-transparent particles 1022 in the retaining wall structure 102 is changed.
In the embodiment of the present invention, the transparent carrier 1011 is mainly used for carrying the circuit layer 1012. When the circuit layer 1012 is energized, the distribution of the charged opaque particles 1022 in the wall structure 102 can be influenced by electromagnetic induction, so as to change the size of the viewing angle of the privacy film 100. In some possible embodiments, the lines distributed in the line layer 1012 may correspond to the retaining wall structures 102 one to one, or may overlap a portion of the retaining wall structures 102, which is not limited herein. But generally not in the pixel region because it has no meaning if the line distribution in the line layer 1012 cannot affect the dam structures 102, and the dam structures 102 are generally not in the pixel region because they are in the pixel region and are not in the meaning of the present invention.
The barrier structure 102 is a transparent cavity, the transparent cavity is filled with a transparent filling liquid 1021 and a plurality of non-transparent particles 1022 are disposed therein, and all the non-transparent particles 1022 carry charges of the same polarity.
In the embodiment of the present invention, the non-transparent particles 1022 may freely move in the transparent filling liquid 1021, so that when the non-transparent particles 1022 receive an external force due to electricity, the distribution manner thereof may be determined as needed.
It should be noted that the non-transparent particles 1022 function to block other directions from view for the adjacent pixels, so that the privacy film 100 can function as intended. Therefore, under other conditions, the higher the non-transparency of the non-transparent particles 1022, the better the peep-proof effect thereof.
In some possible embodiments, fig. 5 is a schematic view of a process for manufacturing the privacy film 100, wherein the process is as follows: using optical transparent adhesive to make a layer of transparent base film; one surface of the transparent base film is provided with a plurality of grooves; filling transparent filling liquid 1021 into all the grooves; placing a plurality of non-transparent particles 1022 in a transparent filling liquid 1021, the non-transparent particles 1022 carrying like charges; a layer of transparent bearing body is made of transparent solid materials; laying a circuit layer in the transparent bearing body; and attaching the transparent bearing body to one surface of the transparent base film, which is provided with the groove.
In some possible embodiments, the transparent base film is made of an optically clear adhesive OCA, and one surface of the transparent base film is a groove in the shape of the retaining wall structure 102, and may also be a transparent resin OCR. The groove is filled with transparent filling liquid 1021 to allow the contents to move freely, and the privacy film 100 can function. In some possible embodiments, the groove may be a rectangular parallelepiped or a cylinder, and in a top view, the groove may be a groove, or may have another shape, as long as the groove is located in the pixel black area when in use, and the shape is not limited herein. It should be noted that, when other conditions are determined, the more pixel black regions provided with the retaining wall structures 102, the better the peep-proof effect is. In the embodiment of the present invention, the transparent base film serves as an adhesive, and serves as a cavity for accommodating the transparent filling liquid 1021 and the opaque particles 1022, and other materials may be used as long as they can serve the above functions, and are not limited herein.
In the transparent filling liquid 1021, a plurality of the non-transparent particles 1022 are disposed, and the non-transparent particles 1022 carry charges of the same polarity, i.e. either positive or negative, which is not limited herein. The groove is filled with filling liquid 1021, and the filling liquid 1021 is filled with charged opaque particles 1022, which is called a retaining wall structure 102 in the embodiment of the invention. In some possible embodiments, the transparent solid material may be a PET material, and may also be a glass material, as long as it is transparent and can be insulated, and is not limited herein.
In the embodiment of the present invention, the circuit layer 1012 is a conductor, and may be made of a metal or other non-metallic conductor material, which is not limited herein. When a voltage is applied to the wiring layer 1012, the non-transparent particles 1022 react accordingly according to the voltage. That is, when the applied voltage is the same as the non-transparent particles 1022 carrying charges, the non-transparent particles 1022 are driven away from the driving layer 101, and are attracted to the driving layer 101.
It should be noted that the circuit layer 1012 in the driving layer 101 can be loaded with an alternating current to control the position of the non-transparent particles 1022 in the wall structures 102 on the wall structures 102. In other possible embodiments, the circuit layer may be divided into two layers, one layer is loaded with charges that are the same as the charges of the non-transparent particles 1022, and the other layer is loaded with charges that are opposite to the charges of the non-transparent particles 1022, so as to control the positions of the non-transparent particles 1022 in the wall structures 102 on the wall structures 102, which is not limited herein.
In some possible embodiments, when the circuit layer is loaded with the charges carried by the non-transparent particles 1022 in the same electrical manner, the non-transparent particles 1022 are far away from the driving layer, and the charges carried by the non-transparent particles 1022 are opposite to each other, until the non-transparent particles 1022 are driven to the corresponding positions, so that the non-transparent particles 1022 are located at the required positions.
In an embodiment of the present invention, the driving layer 101 may be attached to the grooved surface to seal the grooves.
The user can freely set the viewing angles of different display screens according to different use scenes without the trouble of tearing down and sticking the peep-proof film 100. Moreover, when the anti-peeping film 10 is attached to the display screen, each of the retaining wall structures 102 is overlapped with one pixel black area of the display screen, so that the influence of overlapping with a pixel light emitting area on resolution and brightness is avoided.
The privacy film 100 in the present embodiment is described above, and the display device 200 including the privacy film 100 in the present embodiment is described below.
As shown in fig. 2, an embodiment of the present application provides a display device 200, where the display device 200 includes:
the display screen 202 is attached with the peep-proof film 100, and the retaining wall structures 102 of the peep-proof film 100 are correspondingly overlapped with the pixel black areas of the display screen 201 one by one.
In the embodiment of the present invention, the Display screen 201 may be configured in the form of a Liquid Crystal Display (LCD), an Organic Light-Emitting Diode (OLED), and the like, which is not limited herein. In the display panel 201, pixels are distributed, and a place where no pixel exists among the pixels is called a pixel black area. In the embodiment of the present invention, the retaining wall structures 102 of the privacy film 100 may overlap the pixel black regions, and preferably, as shown in fig. 3, the retaining wall structures 102 of the privacy film 100 may overlap the pixel black regions in a one-to-one correspondence, that is, any pixel black region has the retaining wall structure 102 overlapping it, and vice versa.
In some possible embodiments, privacy film 100 and display screen 201 may be bonded by an optically clear adhesive, also referred to as a layer of clear adhesive. The optically Clear adhesive referred to herein may be an Optically Clear Adhesive (OCA) or an Optically Clear Resin (OCR), and is not limited herein.
In some possible embodiments, fig. 6 is a schematic diagram of a process for manufacturing a display device by using the privacy film 100: obtaining a privacy film 100; a transparent adhesive layer is coated on the display screen 201; one side of the driving layer in the anti-peeping film 100 is attached to the transparent adhesive layer, and the retaining wall structures 102 of the anti-peeping film 100 are overlapped with the pixel black regions of the display screen 201 in a one-to-one correspondence manner.
In the embodiment of the present invention, the optically transparent adhesive serves as an adhesive between the display screen 201 and the privacy film 100. In some possible embodiments, the optically clear adhesive may have a buffering effect when pressed or vibrated due to the flowing liquid property of the optically clear adhesive.
The user can freely set the viewing angles of the different display screens 201 according to different use scenes without the trouble of tearing down and attaching the privacy film 100. Moreover, when the privacy film 100 is attached to the display screen 201, each of the retaining wall structures 102 overlaps with one pixel black region of the display screen 201, so that the influence of the overlapping with a pixel light emitting region on the resolution and brightness is avoided.

The user can freely set the visual angle of different display screens according to different use scenes, and the trouble of tearing down the peep-proof film and attaching the peep-proof film is avoided. And because the peep-proof membrane is attached on the display screen, each retaining wall structure is overlapped with one pixel black area of the display screen, and the influence on resolution and brightness caused by the overlapping of the retaining wall structure and a pixel light emitting area is avoided.
The terminal 300 in the embodiment of the present application is described above, and the method for manufacturing the privacy film 100 in the embodiment of the present application is described below.
As shown in fig. 7, the terminal display method includes:
601. and acquiring a visual angle adjusting instruction.
In the embodiment of the present invention, the execution subject is the terminal 300 in the embodiment, and a processor in the terminal may obtain and execute the view angle adjusting instruction. In some possible embodiments, the instruction may be from a user operating on a screen, or may be based on an externally received instruction, which is not limited herein.
602. And adjusting the voltage of the line layer according to the visual angle adjusting instruction to control the distribution mode of the plurality of non-transparent particles in the transparent filling liquid, wherein the distribution mode of the non-transparent particles in the transparent filling liquid determines the size of the display visual angle of the terminal.
In some possible embodiments, if the terminal receives the command to reduce the display viewing angle, the circuit layer is powered on, so that the circuit layer is loaded with a voltage having the same electrical property as the electrical charges carried by the non-transparent particles to drive the non-transparent particles to move in the transparent filling liquid in a direction away from the driving layer, so that the retaining wall structure forms a non-transparent retaining wall with a certain height, and the height determines the size of the display viewing angle of the terminal.
It should be noted that when the circuit layer is loaded with the same electrical charge as the non-transparent particles, the non-transparent particles can be close to the driving layer, so that the height of the retaining wall structure is zero. Control of the retaining wall structure is ensured even when the terminal is turned over.
If the terminal receives an instruction to enlarge the display viewing angle, a voltage with an electric property opposite to that of the electric charge carried by the non-transparent particles or no voltage is loaded on the road layer to drive the non-transparent particles to move in the transparent filling liquid in a direction away from the driving layer, or the non-transparent particles automatically fall on the surface of the driving layer, so that the height of the non-transparent retaining wall of the retaining wall structure is reduced or has no height, and the size of the display viewing angle is determined.
As shown in fig. 8, in other possible embodiments, when the terminal is powered on the driving layer, if the electrical property of the powered voltage is the same as the electrical property of the non-transparent particles, the non-transparent particles are far away from the driving layer due to the principle of like-polarity repulsion, and the non-transparent particles can be intensively distributed in a small segment in the retaining wall structure to achieve the effect of shielding the pixel, shielding the light with a large angle, and achieving the purpose of reducing the viewing angle. In this case, the non-transparent particles can achieve some degree of privacy under the drive of the drive layer.
Specifically, when the voltage is the same as the electrical property of the non-transparent particles and the voltage is larger, the considerable viewing angle of the pixel can reach the minimum theta 3; when the voltage is the same as the electrical property of the non-transparent particles and the voltage is smaller, the considerable viewing angle of the pixel may be the minimum θ 1, and in some possible embodiments, θ 1 may be 180 °, i.e., there is no peeping prevention effect, which is not limited herein; when the electric property of the loaded voltage is the same as that of the non-transparent particles and is opposite to that of the non-transparent particles, the considerable visual angle of the pixel can be controlled to be theta 2 because the voltage with different electric properties is controllable, wherein theta 1 is more than or equal to theta 2 and more than or equal to theta 3.
However, the angle θ 2 'and the angle θ 3' are not actually effective in preventing peeking as shown in fig. 8. In order to achieve a better peeping prevention effect, the non-transparent particles can carry different electric quantities, so that when the driving layer applies voltage, the non-transparent particles can be relatively uniformly distributed in the retaining wall structure, as shown in fig. 9, when the terminal is powered on at the driving layer, the non-transparent particles can be relatively uniformly distributed in the retaining wall structure, a non-transparent retaining wall is formed in the retaining wall structure, and large-angle light is shielded, so that the purpose of reducing the visual angle is achieved. When the electricity is not conducted or the electricity property of the electricity is opposite to the electricity property of the non-transparent particles, the traditional direction of light rays cannot be changed by the transparent wall body, namely, a larger visual angle is recovered, and the purpose of controlling the visual angle can be achieved by the trend of the height of the charged small balls.
The user can freely set the visual angle of different display screens according to different use scenes, and the trouble of tearing down the peep-proof film and attaching the peep-proof film is avoided. And because the peep-proof membrane is attached on the display screen, each retaining wall structure is overlapped with one pixel black area of the display screen, and the influence on resolution and brightness caused by the overlapping of the retaining wall structure and a pixel light emitting area is avoided.
