DETAILED DESCRIPTION

[0030] It should be understood that the terms used herein, the specific structures and functional details disclosed are only for describing specific embodiments and are representative, but the present application can be implemented in many alternative forms and should not be construed as being limited to only the embodiments described herein.

[0031] In addition, unless otherwise clearly specified or limited, "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internally connected between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] The present application is further described below with reference to the accompanying drawings and optional embodiments.

[0033] like Figure 1 As shown, the embodiment of the present application discloses a display device, wherein the display device 10 includes a driving circuit 200 and a display panel 100, wherein the driving circuit 200 includes a selector 210 and a power line 220, wherein the selector 210 is a switch and can be arranged on the display panel 100, or on a COF or a printed circuit board. The power line 220 is connected to the electromagnetic unit 130 through the selector 210 to provide a stable voltage to the electromagnetic unit 130, and the selector 210 controls the conduction between the power line 220 and the electromagnetic unit 130; wherein the selector 210 can be controlled by a program on the display panel 100, or by a mechanical structure on the display device 10, such as a button or knob arranged outside the housing of the display device 10.

[0034] For the detailed design of the display panel 100, please refer to the following specific embodiments:

[0035] like Figure 2 and Figure 3 As shown, Figure 2 This is a diagram of the display panel when the selector is not open. Figure 3It is a schematic diagram of the display panel when the selector is turned on. As a display panel provided in an embodiment of the present application, the display panel 100 includes a first substrate 110 and a second substrate 120 arranged relatively to each other. The display panel 100 also includes an anti-peeping structure located in the display area. The anti-peeping structure includes an electromagnetic unit 130 and a metal telescopic unit 140. The electromagnetic unit 130 is arranged on a side of the first substrate 110 facing the second substrate 120, and the metal telescopic unit 140 is arranged on a side of the second substrate 120 facing the first substrate 110, and is arranged directly opposite to the electromagnetic unit 130.

[0036] When the selector 210 is not turned on, so that the electromagnetic unit 130 is not powered, the metal expansion unit 140 is in a contracted state (also known as a normal state), the electromagnetic unit 130 and the metal expansion unit 140 are not in contact, and there is a gap between the two, and the light emitted by the pixel unit can pass through the gap between the two sides normally and irradiate the side of the display panel 100. When the electromagnetic unit 130 is powered, the metal expansion unit 140 is in an expanded state, and the electromagnetic unit 130 and the metal expansion unit 140 are attached to form a grating to block the light emitted by the pixel unit from irradiating the side of the display panel 100.

[0037] The present application sets an electromagnetic unit 130 and a metal telescopic unit 140 on two substrates of the display panel 100 respectively. When the display panel 100 selects the non-peeping mode, the electromagnetic unit 130 is not powered on. At this time, the metal telescopic unit 140 is in a contracted state, and light can pass through the gap between the electromagnetic unit 130 and the metal telescopic unit 140, so that the display content can be seen from the side of the display panel 100; when the display panel 100 selects the anti-peeping mode, the electromagnetic unit 130 is powered on. At this time, the metal telescopic unit 140 is in an expanded state, and the electromagnetic unit 130 and the metal telescopic unit 140 are attached to form a grating, blocking the light from passing to the side of the display panel 100, so that the display content cannot be seen from the side of the display panel 100, thereby achieving an anti-peeping effect. Since the display panel 100 in the present application can be freely switched between the anti-peeping and non-peeping states, different usage modes can be adjusted according to different scenarios, making the product more convenient to use and conducive to improving the market competitiveness of the product.

[0038] In the embodiment of the present application, the first substrate 110 may be a color filter substrate or an array substrate; correspondingly, the second substrate 120 may be an array substrate or a color filter substrate, which is not limited here.

[0039] In an embodiment of the present application, the metal telescopic unit 140 can be located only on one side of the display area, or on two sides, three sides, or even four sides of the display area, to achieve single-side anti-peeping, double-side anti-peeping, three-side anti-peeping, or full anti-peeping effects.

[0040] As one of the implementation methods, Figure 4 As shown, the display panel 100 includes a plurality of pixel units 170 . In the same row of the pixel units 170 , the anti-peeping structure 300 is disposed between two adjacent pixel units 170 .

[0041] In this embodiment, all the anti-peeping structures 300 in the display panel 100 form a plurality of strip-shaped grid structures; wherein the anti-peeping structures 300 may be on the left and right sides of the pixel unit 170, or on the upper and lower sides of the pixel unit 170. When the anti-peeping structures 300 are on the left and right sides of the pixel unit 170, the display panel 100 can achieve the anti-peeping on the left and right sides; when the anti-peeping structures 300 are on the upper and lower sides of the pixel unit 170, the display panel 100 can achieve the anti-peeping on the upper and lower sides; the specific selection and design is made according to actual needs.

[0042] Moreover, in this embodiment, the pixel unit 170 may represent a sub-pixel, and the anti-peeping structure 300 is disposed between two adjacent sub-pixels; thus, when the anti-peeping state is switched, the anti-peeping effect is better.

[0043] Alternatively, each pixel unit 170 may represent a plurality of sub-pixels arranged in an array, in which case a plurality of sub-pixels are spaced between two adjacent anti-peep structures 300. This method effectively reduces the number of anti-peep structures 300 in the display panel 100, making it easier to design and manufacture; moreover, since the anti-peep structures 300 block light, reducing the number of anti-peep structures 300 can also avoid reducing the aperture ratio of the display panel 100.

[0044] As another implementation method, Figure 5 As shown, the display panel 100 includes a plurality of pixel units 170 , and in the same row of the pixel units 170 , an anti-peeping structure 300 is provided between two adjacent pixel units 170 ; in the same column of the pixel units 170 , an anti-peeping structure 300 is provided between two adjacent pixel units 170 .

[0045] In this embodiment, all the anti-peeping structures 300 in the display panel 100 form a mesh grid structure, and when switched to the anti-peeping state, they can block light on four sides of the pixel unit 170 to achieve a full anti-peeping state.

[0046] Likewise, in this embodiment, the pixel unit 170 may be a sub-pixel or a plurality of sub-pixels arranged in an array.

[0047] Moreover, as a further implementation, all the electromagnetic units 130 in the display panel 100 are connected to the same control line 150, and the control line 150 simultaneously controls all the electromagnetic units 130 in the display panel 100 to be powered on. This method simplifies the switching process and directly realizes full anti-peeping switching with one click.

[0048] As another further implementation, the electromagnetic units 130 located on different sides of the pixel unit 170 are respectively connected to different control lines 150; wherein the electromagnetic units 130 correspond one-to-one to the metal expansion units 140, and each of the control lines 150 controls the electromagnetic units 130 on one side of the pixel unit 170 to be energized.

[0049] At this time, there are four control lines 150 in the display panel 100, the first control line 150 is connected to the electromagnetic unit 130 located on the left side of each pixel unit 170, the second control line 150 is connected to the electromagnetic unit 130 located on the right side of each pixel unit 170, the third control line 150 is connected to the electromagnetic unit 130 located on the front side of each pixel unit 170, and the fourth control line 150 is connected to the electromagnetic unit 130 located on the rear side of each pixel unit 170. Moreover, different control lines 150 are independently controlled, so that different sides of the display panel 100 can be individually controlled for privacy protection, realizing the switching of multiple privacy protection modes such as single-side privacy protection, double-side privacy protection, three-side privacy protection and four-side privacy protection, meeting various usage requirements.

[0050] Regarding the design of the metal expansion unit 140 , the present application provides the following two specific implementations.

[0051] like Figure 6 As shown, as an implementation mode of the metal telescopic unit 140, the metal telescopic unit 140 includes an elastic shading unit 141 and a metal unit 142, the two ends of the elastic shading unit 141 are respectively connected to the second substrate 120 and the metal unit 142, and the metal unit 142 is arranged between the elastic shading unit 141 and the electromagnetic unit 130; when the electromagnetic unit 130 is not powered on, the elastic shading unit 141 is in a contracted state, and there is a distance between the electromagnetic unit 130 and the metal unit 142; when the electromagnetic unit 130 is powered on, the elastic shading unit 141 is in an expanded state, and the electromagnetic unit 130 is in contact with the metal unit 142.

[0052] Specifically, the elastic shading unit 141 can be an elastic structure with shading materials added, the shading materials include carbon nanotubes, graphene, carbon black and other materials, and the constituent materials of the elastic structure include silicone rubber, natural rubber, nitrile rubber and other materials; after the shading material is added to the inside of the elastic structure, an elastic shading unit 141 with elasticity and ability to shield light is formed.

[0053] The metal unit 142 is generally made of a metal material that can be attracted by magnetic force, specifically iron, nickel, cobalt, alloys thereof, ferrite, etc.

[0054] Among them, one end of the elastic light shielding unit 141 is fixed on the second substrate 120 by bonding, clamping, embedding, etc., and the other end of the elastic light shielding unit 141 is fixed to the metal unit 142 by welding, bonding, etc. When the electromagnetic unit 130 is powered on, the electromagnetic unit 130 generates a magnetic field to attract the metal unit 142 to move toward the electromagnetic unit 130. At this time, the metal unit 142 drives the elastic light shielding unit 141 to stretch and unfold. When the metal unit 142 is attached to the electromagnetic unit 130, the elastic light shielding unit 141 is stretched to the longest, and the metal unit 142 and the elastic light shielding unit 141 form a grating. When the electromagnetic unit 130 is powered off, the magnetic field generated by the electromagnetic unit 130 disappears, and the metal unit 142 returns to its original position under the pulling force of the elastic light shielding unit 141, so that the light emitted by the pixel unit 170 passes through between the metal unit 142 and the electromagnetic unit 130, thereby realizing a shared state.

[0055] Of course, in this embodiment, the metal unit 142 may also be located inside the elastic light shielding unit 141 . When the electromagnetic unit 130 is powered on, the metal unit 142 pushes the top of the elastic light shielding unit 141 to abut against the electromagnetic unit 130 .

[0056] In this embodiment, since the elastic shading unit 141 has good elasticity and can be stretched or contracted quickly, it can quickly adjust the state when switching between the anti-peeping state and the non-anti-peeping state to avoid the problem of switching delay. In addition, since the elastic shading unit 141 is made of rubber material and has an insulating effect, it can prevent the metal unit 142 from transmitting current to the second substrate 120 after the electromagnetic unit 130 is energized when the electromagnetic unit 130 is energized, resulting in leakage current.

[0057] like Figure 7As shown, as a second embodiment of the metal telescopic unit 140, the metal telescopic unit 140 is a telescopic metal structure. In this case, the metal telescopic unit 140 is entirely made of metal material, and the metal telescopic unit 140 can be telescopically deformed under the action of magnetic force. Specifically, the metal telescopic unit 140 can be a multi-section sleeve structure similar to a telescopic rod, or a multi-section plate-like structure similar to a telescopic plate. When the electromagnetic unit 130 is powered on, the metal telescopic unit 140 is in an extended state; when the electromagnetic unit 130 is powered off, the metal telescopic unit 140 returns to a contracted state under the action of gravity or the tension of its own internal structure.

[0058] In this embodiment, since the metal telescopic unit 140 is made of metal material as a whole and has good strength, it can maintain a straight state during the stretching and contraction process, thereby ensuring the stability of the product when switching states.

[0059] In addition, when the metal expansion unit 140 is stretched, the cross section of the metal expansion unit 140 may be an isosceles trapezoid, that is, the width of the metal expansion unit 140 gradually decreases from the second substrate 120 to the first substrate 110. At this time, the connection area between the bottom of the metal expansion unit 140 and the second substrate 120 is large, and the stabilization effect is good; while the top area of ​​the metal expansion unit 140 is small, and the pressure is also small, so it is easier to stretch.

[0060] For the electromagnetic unit 130 in the embodiment of the present application, Figure 8 and Fig. 9 As shown, the electromagnetic unit 130 can adopt an electromagnetic coil 131 structure, and the electromagnetic coil 131 can be a square coil or a circular coil; because the magnetic field of the electromagnetic coil 131 is stronger toward the middle, when the electromagnetic coil 131 is energized, the metal expansion unit 140 can be extended toward the center to avoid the offset problem. Moreover, as an arrangement design of the electromagnetic unit 130, such as Fig.10 As shown, the number of the electromagnetic coils 131 corresponds to the number of the metal expansion and contraction units 140 , and both the electromagnetic coils 131 and the metal expansion and contraction units 140 are located on the side of the pixel unit 170 .

[0061] In this embodiment, for the control line 150 connected to the electromagnetic coil 131, the control line 150 can be formed synchronously with the metal line structure in the substrate, so as to reduce the process; for example, when the first substrate 110 is an array substrate, the control line 150 and the electromagnetic coil 131 are made on the array substrate, and the control line 150 is formed in the same process as the data line, scan line or common line on the array substrate, and then the control line 150 is connected to the electromagnetic coil 131 by punching. Of course, the control line 150 can also be made separately on the side of the first substrate 110 facing the second substrate 120, and set on the same layer as the electromagnetic coil 131.

[0062] Furthermore, a protective layer may be added outside the electromagnetic coil 131 and the metal expansion unit 140 as needed to avoid problems such as leakage and corrosion, thereby increasing the service life of the product.

[0063] like Fig.11 As shown, as another arrangement design of the electromagnetic unit 130, the electromagnetic unit 130 is an electromagnetic coil 131, and the anti-peep structure 300 includes one electromagnetic coil 131 and at least two metal telescopic units 140, the electromagnetic coil 131 is arranged around the pixel unit 170, and the metal telescopic unit 140 is arranged on the side of the pixel unit 170; the electromagnetic coil 131 corresponds to at least two of the metal telescopic units 140, and the electromagnetic coil 131 simultaneously controls at least two of the metal telescopic units 140.

[0064] In this embodiment, an electromagnetic coil 131 is directly surrounded outside each pixel unit 170, and the metal expansion unit 140 can be set on two sides, three sides or four sides of the pixel unit 170. When the electromagnetic coil 131 is energized, multiple metal expansion units 140 located below the electromagnetic coil 131 are stretched at the same time to achieve anti-peeping. Compared with the solution of setting the electromagnetic coil 131 on different sides of each pixel unit 170, this embodiment can effectively reduce the number of electromagnetic coils 131, make it more convenient to design the electromagnetic coil 131, and also reduce the arrangement of the control line 150.

[0065] In addition, since there will be a large number of support columns 160 (PS) structures in the display panel 100, and the support columns 160 are generally located between the pixel units 170, the embodiment of the present application can also combine the extended metal expansion unit 140 and the original support columns 160 to form a light-blocking structure to improve the shading effect.

[0066] As one of the implementation methods, Fig.12 As shown, the metal telescopic unit 140 is made into a hollow shape, similar to a spring structure, so that the metal telescopic unit 140 corresponds to the support column 160 one by one, and the metal telescopic unit 140 is sleeved and surrounded on the support column 160. In addition, the support column 160 is opaque, and when the electromagnetic coil 131 is energized, the metal telescopic unit 140 is stretched along the height direction of the support column 160. Since the metal telescopic units 140 are densely distributed and have a large width, the metal telescopic units 140 can form a grating.

[0067] In this embodiment, the support column 160 can be a main support interval or a secondary support interval in the original display panel 100. Since the metal telescopic unit 140 moves along the height direction of the support column 160, the stability of the metal telescopic unit 140 is ensured and it will not deviate.

[0068] Of course, as another implementation, the metal telescopic unit 140 and the support column 160 can also be arranged side by side. Since the support column 160 is not light-transmissive, when the metal telescopic unit 140 is extended, the metal telescopic unit 140 and the support column 160 form a double light-blocking structure to improve the anti-peeping effect.

[0069] In addition, the inventive concept of the present application can form a large number of implementation plans, but the length of the application document is limited and it is impossible to list them one by one. Therefore, under the premise of no conflict, the various implementation plans or technical features described above can be arbitrarily combined to form a new embodiment. After the various implementation plans or technical features are combined, the original technical effects will be enhanced.

[0070] The above content is a further detailed description of the present application in combination with specific optional implementation methods, and it cannot be determined that the specific implementation of the present application is limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, several simple deductions or substitutions can be made without departing from the concept of the present application, which should be deemed to fall within the scope of protection of the present application.
