Description

  The present invention relates to the field of optical protective film technology, and more particularly to a peep prevention film, a display device, a terminal, and a method of manufacturing the peep prevention film.

  Current terminal devices such as mobile phones and tablet computers generally use display screens with wide viewing angles. Large viewing angles can provide a very good viewing effect for reading or viewing. However, while the user enjoys the display effect of the screen, surrounding people can also clearly see the content displayed on the display screen. This greatly increases the potential risk of privacy.

  Currently, in the market, a solution for narrowing the viewing angle of the display screen of a terminal device such as a mobile phone or tablet is to attach a peeping prevention film to the terminal device, for example, attach a peeping prevention film to a notebook computer. It is. The anti-peep film is also mounted on the surface of the screen of most ATM machines in order to narrow the viewing angle of the display screen, and the displayed content can be clearly seen only at the viewing angle of the operator, It protects privacy. The principle of the anti-peep film is the polarization effect, and although the viewing angle can be narrowed, the viewing angle has only one range. Also, when the anti-peep film is mounted on the surface of the display screen, only this range can be used unless the anti-peep film is peeled off, which wastes cost and increases the difficulty of operation.

As shown in FIG. 1, an embodiment of the present application provides a peep prevention film 100, which comprises:
A plurality of retaining wall structures 102 are provided on the driver layer 101 including the driver layer 101 and the retaining wall structure 102.

  In this embodiment of the present invention, when a peeping prevention film 100 is used, ie, a peeping prevention film is mounted on the display screen and a voltage is applied to the distribution method driver layer 101, the viewing angle of the display screen Can be changed by using the anti-peep film 100. It should be noted that both the magnitude of the applied voltage and the electrical properties affect the change of the viewing angle of the display screen by the anti-peep film 100.

  The holding wall structure 102 is a transparent cavity, and the transparent cavity is filled with the transparent filling liquid 1021 and the opaque particles 1022, and the opaque particles 1022 carry an electric charge.

  In this embodiment of the invention, the clear fill liquid 1021 may be a clear non-corrosive solution, which is not limited herein. In this embodiment of the invention, the opaque particles may be pure black particles, white particles, or mixed particles, provided that the particles are opaque active particles. And may be of any material, which is not limited herein. Also, the shape of the opaque particles 1022 may be spherical or cubic, and is not limited herein as long as the opaque particles 1022 are sufficiently small to flow in the clear fill liquid 1021. . The material of the opaque particles 1022 may be an active metal or another material capable of carrying an electrical charge, which is not limited herein. It is noted that it is common knowledge that the opaque particles 1022 can be activated, and details are not described herein.

  In this embodiment of the invention, the retaining wall structure 102 determines the change in the viewing angle of the display screen by the anti-peep film 100. In some possible embodiments, when the peep protection film 100 is attached to the display screen, the retaining wall structure 102 is next to the pixels of the display screen. In general, the retaining wall structure 102 is disposed perpendicular to the driver layer 101. Of course, the retaining wall structure 102 may also be disposed obliquely to the driver layer 101. The holding wall structure 102 is filled with the transparent filling liquid 1021 and the opaque particles 1022, and the distribution method of the opaque particles 1022 may be changed by the driving of the driver layer 101.

  Specifically, when no voltage is applied to the driver layer 101, the opaque particles 1022 remain at the bottom of the holding wall structure 102 close to the driver layer 101, and the voltage is applied to the driver layer 101. The distribution of the particles 1022 changes, for example, the opaque particles 1022 are driven to move to the middle or upper part of the holding wall structure 102 in order to block the view from an angle of the display screen, or the holding wall It is evenly distributed within the structure 102, thereby providing a peep prevention effect.

  In this embodiment of the present invention, a plurality of retaining wall structures 102 may be disposed on one side of the driver layer 101 and changes in the distribution method of the opaque particles 1022 in the retaining wall structure 102 may be driven by the driver layer 101 . Specifically, when a voltage is applied to the driver layer 101, the distribution method of the opaque particles 1022 in the retaining wall structure 102 is directly affected to determine the viewing angle of the anti-peep film 100. The opaque particles 1022 can be flexibly controlled according to the magnitude of the voltage applied to the driver layer 101. Therefore, the viewing angle of the anti-peep film 100 can also be flexibly controlled. In general, a plurality of retaining wall structures 102 are required, and preferably, when applied, the retaining wall structures are accurately distributed to non-pixel areas of the display screen, ie, black pixel areas, so that they are The wide angle mode does not block any pixels, and the angle is well controlled in the narrow angle mode. In other possible embodiments, if desired, the retaining wall structure 102 may be disposed only in the strip of the longitudinal black pixel area, or the retaining wall structure 102 may be arranged in the lateral black pixel area The holding wall structure 102 may be arranged according to other requirements, which is not limited herein.

  The driver layer 101 includes a transparent carrier 1011 and a wiring layer 1012. The wiring layer 1012 is disposed in the transparent carrier 1011, and the distribution state of the opaque particles 1022 in the holding wall structure 102 changes when a voltage is applied to the wiring layer 1012.

  In this embodiment of the invention, the driver layer 101 comprises a transparent carrier 1011 and a wiring layer 1012. The material of the transparent carrier 1011 may be polyethylene terephthalate (English: Polyethylene terephtalate, PET for short) or may be glass, limited herein if the material is non-conductive and transparent I will not. The wiring layer 1012 is a conductor and may be formed of metal or another non-metallic conductor material, which is not limited herein.

  The wiring layer 1012 is disposed in the transparent carrier 1011, and the wiring layer 1012 is disposed in the transparent carrier, and the distribution of the opaque particles 1022 in the holding wall structure 102 changes when a voltage is applied to the wiring layer 1012. Do.

  In this embodiment of the invention, the transparent carrier 1011 is primarily configured to carry the wiring layer 1012. When the power is turned on, the wiring layer 1012 may affect the distribution of the opaque active particles 1022 in the holding wall structure 102 in response to electromagnetic induction, whereby the viewing angle of the anti-see-through film 100 Change. In some possible embodiments, the wires distributed to the wiring layer 1012 may correspond to the retaining wall structure 102 one by one or may overlap the retaining wall structure 102, which There is no limitation in the specification. However, when the line distributed to the wiring layer 1012 can not affect the holding wall structure 102, the wiring is not used in general, so the wiring is not generally arranged in the pixel area, and the holding wall structure is arranged in the pixel area If so, in the present invention, the retaining wall structure 102 is generally not disposed in the pixel area, as the retaining wall structure is also useless.

  The holding wall structure 102 is a transparent cavity, and the transparent cavity is filled with a transparent filling liquid 1021 and a plurality of opaque particles 1022, all of which carry an electric charge.

  In this embodiment of the invention, the opaque particles 1022 move freely in the transparent fill liquid 1021 so that when external force is applied to the opaque particles 1022 by voltage, the distribution method of the opaque particles 1022 can be determined according to requirements. It can.

  It should be noted that the function of the opaque particles 1022 is to block the view from the other direction for the pixels adjacent to the opaque particles 1022 so that the anti-peep film 100 can play a proper role. Thus, the higher opacity of the opaque particles 1022 indicates a better anti-see-through function when the other conditions are constant.

  As shown in FIG. 5, in some possible embodiments, the manufacturing technology of the anti-peep film 100 uses an optical clear adhesive to create a layer of a transparent base film, one of the transparent base films A plurality of grooves are arranged on the surface, all the grooves are filled with the transparent filling liquid 1021, a plurality of opaque particles 1022 are arranged in the transparent filling liquid 1021, the opaque particles 1022 carry an electric charge, and transparent solid material is used. The transparent carrier layer is formed, the wiring layer is disposed in the transparent carrier, and the transparent carrier is mounted on the side of the transparent base film on which the groove is provided.

  In some possible embodiments, the optical transparent adhesive OCA is used as the material of the transparent base film, and the groove of the holding wall structure 102 may be provided on one side of the transparent base film to form an optical transparent resin OCR. Since the transparent filling liquid 1021 is filled in the groove, the object in the transparent filling liquid can move freely, and the anti-seeing film 100 can act. In some possible embodiments, the grooves may be rectangular or cylindrical, and from the top view the grooves may be trenches, or the grooves may be black pixels in use It may be another shape that assumes to be in the area. This is not limited herein. It should be noted that if the other conditions are constant, the more black pixel areas in which the retaining wall structure 102 is disposed indicate a better anti-see-through effect. In this embodiment of the present invention, the transparent base film acts as an adhesive, and the transparent base film is used as a cavity and serves to contain the transparent filling liquid 1021 and the opaque particles 1022. The transparent base film may be any other material as long as it can play the above-mentioned role, and is not limited herein.

  A plurality of opaque particles 1022 are disposed in the transparent fill liquid 1021 and the opaque particles 1022 may carry charge, ie, but not limited to carrying a positive charge or a negative charge. In the present embodiment of the invention, the groove is a retaining wall structure 102 when the groove is filled with the filling liquid 1021 and the opaque active particles 1022 are arranged in the filling liquid 1021. In some possible embodiments, the transparent solid material may be polyethylene terephthalate PET, or it may be glass if the material is clear and thermally insulated, which is not limited herein.

  In this embodiment of the invention, the wiring layer 1012 is a conductor and may be formed of metal or other non-metallic conductor material, which is not limited herein. When a voltage is applied to the line wiring layer 1012, the opaque particles 1022 react correspondingly in response to the voltage. That is, if the electrical properties of the applied voltage are the same as the electrical properties of the charge carried by the opaque particles 1022, the opaque particles 1022 are driven away from the driver layer 101, and conversely, the opaque particles 1022 are It is adsorbed as it approaches layer 101.

  It should be noted that an alternating current may be applied to the wiring layer 1012 of the driver layer 101 to control the position of the opaque particles 1022 in the retaining wall structure 102. In another possible embodiment, the wiring layer may be divided into two layers. A charge having the same electrical properties as the opaque particles 1022 is applied to one layer, and a charge having the opposite electrical properties to the opaque particles 1022 is applied to the other layer, and the opaque particles in the retaining wall structure 102 are Control the position of 1022. This is not limited to the present specification.

  In some possible embodiments, the opaque particles 1022 are spaced from the driver layer when the same electrical charge is applied to the wiring layer as the electrical properties are carried by the opaque particles 1022, and the opaque particles 1022 are opaque. A charge opposite to that of the charge carried by the opaque particles 1022 may be applied such that the particles 1022 are in the required position.

  No groove is provided on one side of the transparent base film, a groove is provided on the other side, and the filling liquid 1021 is present in the groove. In this case, it is necessary to seal the other side, otherwise the liquid in the groove may leak. In this embodiment of the invention, the driver layer 101 may be attached to the side with the groove so as to seal the groove.

  The user can peel off the peep protection film and then freely set different viewing angles of the display screen according to different usage scenarios without attaching the peep protection film. In addition, when the peeping prevention film is mounted on the display screen, each holding wall structure completely overlaps the black pixel area of the display screen, so the holding wall structure does not overlap with the pixel light emitting area, and the resolution and brightness are affected. Absent.

  As mentioned above, although terminal 300 in an embodiment of this application was explained, a manufacturing method of peep prevention film 100 in an embodiment of this application is explained below.

  As shown in FIG. 7, the terminal display method includes the following steps.

  601. Acquire the viewing angle adjustment instruction.

  In this embodiment of the present invention, the execution body is the terminal 300 in the embodiment, and the processor of the terminal may obtain and execute the view angle adjustment command. In some possible embodiments, the instructions may be operations performed by the user on the screen or may be received instructions, which is not limited herein.

  602. The voltage of the wiring layer is adjusted according to the view angle adjustment instruction to control the distribution method of the plurality of opaque particles in the transparent filling liquid, and the distribution method of the plurality of opaque particles in the transparent filling liquid decide.

  In some possible embodiments, if the command received by the terminal reduces the viewing angle, the wiring layer is turned on and a voltage having the same electrical characteristics as the electrical characteristics of the charge carried by the opaque particles is transparent. Applied to the wiring layer to drive the opaque particles in the fill liquid away from the driver layer. Thus, the retaining wall structure forms an opaque retaining wall with a specific height, the height of the retaining wall determining the display viewing angle of the terminal.

  When the same charge as that of the opaque particles is applied to the wiring layer, the opaque particles can be close to the driver layer so that the height of the holding wall structure becomes zero. Control of the retaining wall structure can be ensured even if the terminal is rotated.

  If the command received by the terminal causes the viewing angle to be wide, it is transparent since a voltage opposite to the electrical properties of the charge carried by the opaque particles is applied to the wiring layer or no voltage is applied. The opaque particles in the filling liquid separate from the driver layer, or the opaque particles automatically fall on the surface of the driver layer. In this way, the height of the opaque retaining wall of the retaining wall structure is reduced or zero, thereby determining the viewing angle of view.

  As shown in FIG. 8, in some other possible embodiments, when the terminal is powered on at the driver layer, the electrical characteristics of the voltage for powering up are the same as the electrical characteristics of the non-transparent particles In the case where similar charges are separated from the driver layer on the principle that they repel each other, the opaque particles are intensively distributed to a small part in the retaining wall structure and serve to block the pixels, and the viewing angle is It becomes narrow. In this case, driven by the driver layer, the opaque particles can play a role in preventing some snooping.

  Specifically, if the voltage and the opaque particles have the same electrical characteristics and the voltage is relatively large, the minimum viewing angle at which the pixel can be seen may be θ3, and the voltage and the non-transparent particles have the same electrical characteristics If the voltage is relatively small, the minimum viewing angle at which the pixel can be viewed may be θ1. In some possible embodiments, θ 1 may be 180 degrees, ie there is no peep prevention effect, which is not limited herein. If a portion of the applied voltage has the same electrical characteristics as the opaque particles and another portion of the applied voltage has the opposite electrical characteristics, it may control the magnitude of the voltage with different electrical characteristics, θ 1 It is θθ2 ≧ θ3.

  However, the angle θ2 'and the angle θ3' shown in FIG. 8 do not have a peeping prevention effect in practice. The opaque particles may carry different amounts of electricity to achieve a better anti-see-through effect. In this way, when voltage is applied to the driver layer, the opaque particles can be evenly distributed within the retaining wall structure. As shown in FIG. 9, when the driver layer is turned on, the opaque particles may be evenly distributed within the retaining wall structure to narrow the viewing angle to block light from large angles, and the opacity retention The wall may be formed into a retaining wall structure. If the power of the terminal is not turned on, or if the electrical characteristics of the voltage at power on are opposite to the electrical characteristics of the opaque particles, the transparent retaining wall does not change the direction of the conventional light and the height of the small live ball Control the viewing angle.

  The user can freely set different viewing angles of the display screen according to different usage scenarios without peeling off the peeping prevention film and then wearing the peeping prevention film. In addition, when the peeping prevention film is mounted on the display screen, each holding wall structure completely overlaps the black pixel area of the display screen, so the holding wall structure does not overlap with the pixel light emitting area, and the resolution and brightness are affected. Absent.

  Current terminal devices such as mobile phones and tablet computers generally use display screens with wide viewing angles. Large viewing angles can provide a very good viewing effect for reading or viewing. However, while the user enjoys the display effect of the screen, surrounding people can also clearly see the content displayed on the display screen. This greatly increases the potential risk of privacy.

  Currently, in the market, a solution for narrowing the viewing angle of the display screen of a terminal device such as a mobile phone or tablet is to attach a peeping prevention film to the terminal device, for example, attach a peeping prevention film to a notebook computer.

As shown in FIG. 1, an embodiment of the present application provides a peep prevention film 100, which comprises:
A plurality of retaining wall structures 102 are provided on the driver layer 101 including the driver layer 101 and the retaining wall structure 102.

  In this embodiment of the present invention, when a peeping prevention film 100 is used, ie, a peeping prevention film is mounted on the display screen and a voltage is applied to the distribution method driver layer 101, the viewing angle of the display screen Can be changed by using the anti-peep film 100. It should be noted that both the magnitude of the applied voltage and the electrical properties affect the change of the viewing angle of the display screen by the anti-peep film 100.

  The holding wall structure 102 is a transparent cavity, and the transparent cavity is filled with the transparent filling liquid 1021 and the opaque particles 1022, and the opaque particles 1022 carry an electric charge.

  In this embodiment of the invention, the clear fill liquid 1021 may be a clear non-corrosive solution, which is not limited herein. In this embodiment of the invention, the opaque particles may be pure black particles, white particles, or mixed particles, provided that the particles are opaque active particles. And may be of any material, which is not limited herein. Also, the shape of the opaque particles 1022 may be spherical or cubic, and is not limited herein as long as the opaque particles 1022 are sufficiently small to flow in the clear fill liquid 1021 . The material of the opaque particles 1022 may be an active metal or another material capable of carrying an electrical charge, which is not limited herein. It is noted that it is common knowledge that the opaque particles 1022 can be activated, and details are not described herein.

  In this embodiment of the invention, the retaining wall structure 102 determines the change in the viewing angle of the display screen by the anti-peep film 100. In some possible embodiments, when the peep protection film 100 is attached to the display screen, the retaining wall structure 102 is next to the pixels of the display screen. In general, the retaining wall structure 102 is disposed perpendicular to the driver layer 101. Of course, the retaining wall structure 102 may also be disposed obliquely to the driver layer 101. The holding wall structure 102 is filled with the transparent filling liquid 1021 and the opaque particles 1022, and the distribution method of the opaque particles 1022 may be changed by the driving of the driver layer 101.

  Specifically, when no voltage is applied to the driver layer 101, the opaque particles 1022 remain at the bottom of the holding wall structure 102 close to the driver layer 101, and the voltage is applied to the driver layer 101. The distribution of the particles 1022 changes, for example, the opaque particles 1022 are driven to move to the middle or upper part of the holding wall structure 102 in order to block the view from an angle of the display screen, or the holding wall It is evenly distributed within the structure 102, thereby providing a peep prevention effect.

  In this embodiment of the present invention, a plurality of retaining wall structures 102 may be disposed on one side of the driver layer 101 and changes in the distribution method of the opaque particles 1022 in the retaining wall structure 102 may be driven by the driver layer 101 . Specifically, when a voltage is applied to the driver layer 101, the distribution method of the opaque particles 1022 in the retaining wall structure 102 is directly affected to determine the viewing angle of the anti-peep film 100. The opaque particles 1022 can be flexibly controlled according to the magnitude of the voltage applied to the driver layer 101. Therefore, the viewing angle of the anti-peep film 100 can also be flexibly controlled. In general, a plurality of retaining wall structures 102 are required, and preferably, when applied, the retaining wall structures are accurately distributed to non-pixel areas of the display screen, ie, black pixel areas, so that they are The wide angle mode does not block any pixels, and the angle is well controlled in the narrow angle mode. In other possible embodiments, if desired, the retaining wall structure 102 may be disposed only in the strip of the longitudinal black pixel area, or the retaining wall structure 102 may be arranged in the lateral black pixel area The holding wall structure 102 may be arranged according to other requirements, which is not limited herein.

  The driver layer 101 includes a transparent carrier 1011 and a wiring layer 1012. The wiring layer 1012 is disposed in the transparent carrier 1011, and the distribution state of the opaque particles 1022 in the holding wall structure 102 changes when a voltage is applied to the wiring layer 1012.

In this embodiment of the invention, the driver layer 101 comprises a transparent carrier 1011 and a wiring layer 1012. The material of the transparent carrier 1011 may be polyethylene terephthalate ( polyethylene terephthalate, or PET for short) or may be glass, and is not limited herein as long as the material is nonconductive and transparent. . The wiring layer 1012 is a conductor and may be formed of metal or another non-metallic conductor material, which is not limited herein.

Wiring layer 1012 is disposed on the transparent carrier 1011, when the voltage is applied to the wiring layer 1012, the allocation state of the opaque particles 1022 retaining wall structure 102 is changed.

  In this embodiment of the invention, the transparent carrier 1011 is primarily configured to carry the wiring layer 1012. When the power is turned on, the wiring layer 1012 may affect the distribution of the opaque active particles 1022 in the holding wall structure 102 in response to electromagnetic induction, whereby the viewing angle of the anti-see-through film 100 Change. In some possible embodiments, the wires distributed to the wiring layer 1012 may correspond to the retaining wall structure 102 one by one or may overlap the retaining wall structure 102, which There is no limitation in the specification. However, when the line distributed to the wiring layer 1012 can not affect the holding wall structure 102, the wiring is not used in general, so the wiring is not generally arranged in the pixel area, and the holding wall structure is arranged in the pixel area If so, in the present invention, the retaining wall structure 102 is generally not disposed in the pixel area, as the retaining wall structure is also useless.

  The holding wall structure 102 is a transparent cavity, and the transparent cavity is filled with a transparent filling liquid 1021 and a plurality of opaque particles 1022, all of which carry an electric charge.

  In this embodiment of the invention, the opaque particles 1022 move freely in the transparent fill liquid 1021 so that when external force is applied to the opaque particles 1022 by voltage, the distribution method of the opaque particles 1022 can be determined according to requirements. It can.

  It should be noted that the function of the opaque particles 1022 is to block the view from the other direction for the pixels adjacent to the opaque particles 1022 so that the anti-peep film 100 can play a proper role. Thus, the higher opacity of the opaque particles 1022 indicates a better anti-see-through function when the other conditions are constant.

  As shown in FIG. 5, in some possible embodiments, the manufacturing technology of the anti-peep film 100 uses an optical clear adhesive to create a layer of a transparent base film, one of the transparent base films A plurality of grooves are arranged on the surface, all the grooves are filled with the transparent filling liquid 1021, a plurality of opaque particles 1022 are arranged in the transparent filling liquid 1021, the opaque particles 1022 carry an electric charge, and transparent solid material is used. The transparent carrier layer is formed, the wiring layer is disposed in the transparent carrier, and the transparent carrier is mounted on the side of the transparent base film on which the groove is provided.

  In some possible embodiments, the optical transparent adhesive OCA is used as the material of the transparent base film, and the groove of the holding wall structure 102 may be provided on one side of the transparent base film to form an optical transparent resin OCR. Since the transparent filling liquid 1021 is filled in the groove, the object in the transparent filling liquid can move freely, and the anti-seeing film 100 can act. In some possible embodiments, the grooves may be rectangular or cylindrical, and from the top view the grooves may be trenches, or the grooves may be black pixels in use It may be another shape that assumes to be in the area. This is not limited herein. It should be noted that if the other conditions are constant, the more black pixel areas in which the retaining wall structure 102 is disposed indicate a better anti-see-through effect. In this embodiment of the present invention, the transparent base film acts as an adhesive, and the transparent base film is used as a cavity and serves to contain the transparent filling liquid 1021 and the opaque particles 1022. The transparent base film may be any other material as long as it can play the above-mentioned role, and is not limited herein.

  A plurality of opaque particles 1022 are disposed in the transparent fill liquid 1021 and the opaque particles 1022 may carry charge, ie, but not limited to carrying a positive charge or a negative charge. In the present embodiment of the invention, the groove is a retaining wall structure 102 when the groove is filled with the filling liquid 1021 and the opaque active particles 1022 are arranged in the filling liquid 1021. In some possible embodiments, the transparent solid material may be polyethylene terephthalate PET, or it may be glass if the material is clear and thermally insulated, which is not limited herein.

  In this embodiment of the invention, the wiring layer 1012 is a conductor and may be formed of metal or other non-metallic conductor material, which is not limited herein. When a voltage is applied to the line wiring layer 1012, the opaque particles 1022 react correspondingly in response to the voltage. That is, if the electrical properties of the applied voltage are the same as the electrical properties of the charge carried by the opaque particles 1022, the opaque particles 1022 are driven away from the driver layer 101, and conversely, the opaque particles 1022 are It is adsorbed as it approaches layer 101.

  It should be noted that an alternating current may be applied to the wiring layer 1012 of the driver layer 101 to control the position of the opaque particles 1022 in the retaining wall structure 102. In another possible embodiment, the wiring layer may be divided into two layers. A charge having the same electrical properties as the opaque particles 1022 is applied to one layer, and a charge having the opposite electrical properties to the opaque particles 1022 is applied to the other layer, and the opaque particles in the retaining wall structure 102 are Control the position of 1022.

  The user can peel off the peep protection film and then freely set different viewing angles of the display screen according to different usage scenarios without attaching the peep protection film. In addition, when the peeping prevention film is mounted on the display screen, each holding wall structure completely overlaps the black pixel area of the display screen, so the holding wall structure does not overlap with the pixel light emitting area, and the resolution and brightness are affected. Absent.

  As mentioned above, although terminal 300 in an embodiment of this application was explained, a manufacturing method of peep prevention film 100 in an embodiment of this application is explained below.

  As shown in FIG. 7, the terminal display method includes the following steps.

  601. Acquire the viewing angle adjustment instruction.

  In this embodiment of the present invention, the execution body is the terminal 300 in the embodiment, and the processor of the terminal may obtain and execute the view angle adjustment command. In some possible embodiments, the instructions may be operations performed by the user on the screen or may be received instructions, which is not limited herein.

  602. The voltage of the wiring layer is adjusted according to the view angle adjustment instruction to control the distribution method of the plurality of opaque particles in the transparent filling liquid, and the distribution method of the plurality of opaque particles in the transparent filling liquid decide.

In some possible embodiments, if the command received by the terminal narrows the viewing angle, the wiring layer is turned on and a voltage having the same electrical characteristics as the electrical characteristics of the charge carried by the opaque particles is The opposite direction to the wiring layer is to drive the opaque particles in the clear fill liquid away from the driver layer. Thus, the retaining wall structure forms an opaque retaining wall with a specific height, the height of the retaining wall determining the display viewing angle of the terminal.

  When the same charge as that of the opaque particles is applied to the wiring layer, the opaque particles can be close to the driver layer so that the height of the holding wall structure becomes zero. Control of the retaining wall structure can be ensured even if the terminal is rotated.

If the command received by the terminal causes the viewing angle to be wide, it is transparent since a voltage opposite to the electrical properties of the charge carried by the opaque particles is applied to the wiring layer or no voltage is applied. The opaque particles in the filling liquid move in contact with the driver layer, or the opaque particles automatically fall on the surface of the driver layer. In this way, the height of the opaque retaining wall of the retaining wall structure is reduced or zero, thereby determining the viewing angle of view.

  As shown in FIG. 8, in some other possible embodiments, when the terminal is powered on at the driver layer, the electrical characteristics of the voltage for powering up are the same as the electrical characteristics of the non-transparent particles In the case where similar charges are separated from the driver layer on the principle that they repel each other, the opaque particles are intensively distributed to a small part in the retaining wall structure and serve to block the pixels, and the viewing angle is It becomes narrow. In this case, driven by the driver layer, the opaque particles can play a role in preventing some snooping.

  Specifically, if the voltage and the opaque particles have the same electrical characteristics and the voltage is relatively large, the minimum viewing angle at which the pixel can be seen may be θ3, and the voltage and the non-transparent particles have the same electrical characteristics If the voltage is relatively small, the minimum viewing angle at which the pixel can be viewed may be θ1. In some possible embodiments, θ 1 may be 180 degrees, ie there is no peep prevention effect, which is not limited herein. If a portion of the applied voltage has the same electrical characteristics as the opaque particles and another portion of the applied voltage has the opposite electrical characteristics, it may control the magnitude of the voltage with different electrical characteristics, θ 1 It is θθ2 ≧ θ3.

  However, the angle θ2 'and the angle θ3' shown in FIG. 8 do not have a peeping prevention effect in practice. The opaque particles may carry different amounts of electricity to achieve a better anti-see-through effect. In this way, when voltage is applied to the driver layer, the opaque particles can be evenly distributed within the retaining wall structure. As shown in FIG. 9, when the driver layer is turned on, the opaque particles may be evenly distributed within the retaining wall structure to narrow the viewing angle to block light from large angles, and the opacity retention The wall may be formed into a retaining wall structure. If the power of the terminal is not turned on, or if the electrical characteristics of the voltage at power on are opposite to the electrical characteristics of the opaque particles, the transparent retaining wall does not change the direction of the conventional light and the height of the small live ball Control the viewing angle.

  The user can freely set different viewing angles of the display screen according to different usage scenarios without peeling off the peeping prevention film and then wearing the peeping prevention film. In addition, when the peeping prevention film is mounted on the display screen, each holding wall structure completely overlaps the black pixel area of the display screen, so the holding wall structure does not overlap with the pixel light emitting area, and the resolution and brightness are affected. Absent.
