Description

Technical Field

[0001] The present disclosure relates to the field of electronic technologies, and particularly to a display screen and an electronic device. Background Art

[0002] Folding-screen mobile phones and folding-screen computers have gradually become popular electronic products among people. To improve the user experience, the size of the folding screen is getting larger and larger. When the folding screen is in the folded state, it is difficult to keep the first display part and the second display part of the folding screen in close contact only by the acting force of the rotating shaft. Therefore, relevant technicians set magnets on the first display part and the second display part. When the folding screen is in the folded state, the first display part and the second display part are kept in close contact by the magnetic force of the magnets. However, when the folding screen is in the unfolded state, the magnetic force of the magnets is likely to attract magnetic foreign objects. Since the folding screen is a flexible screen, when the folding screen is in the folded state and the foreign object is clamped between the first display part and the second display part, it is likely to cause colored bright spots or black masses to appear on the folding screen. When the magnetic force is relatively large, it may even directly damage the folding screen. Summary of the Invention

[0003] The present disclosure provides a display screen and an electronic device.

[0004] In a first aspect, an embodiment of the present disclosure provides a display screen, including:

[0005] A first display screen;

[0006] A second display screen;

[0007] A magnetic component, at least one of the magnetic components is respectively provided on the first display screen and the second display screen. When the first display screen and the second display screen are in the folded state, the positions of the magnetic poles of the magnetic components provided on the first display screen and the second display screen are opposite and the polarities are opposite;

[0008] Wherein, the magnetic component includes a first magnetic pole, a second magnetic pole, a connecting part connecting the first magnetic pole and the second magnetic pole, and a magnetic conductor, and the polarities of the first magnetic pole and the second magnetic pole are opposite;

[0009] When the first display screen and the second display screen are in the unfolded state, the magnetic conductor confines the magnetic lines of force between the first magnetic pole and the second magnetic pole in the magnetic component;

[0010] When the first display screen and the second display screen are in the folded state, the magnetic conductor confines the magnetic lines of force between the first magnetic pole in the magnetic component of the first display screen and the second magnetic pole in the magnetic component of the second display screen opposite thereto, and between the second magnetic pole in the magnetic component of the first display screen and the first magnetic pole in the magnetic component of the second display screen opposite thereto.

[0011] In a second aspect, embodiments of the present disclosure provide an electronic device, including a display screen, wherein the display screen includes any one of the display screens provided by the embodiments of the present disclosure.

[0012] For the display screen provided by the embodiments of the present disclosure, a connecting portion connects a first magnetic pole and a second magnetic pole, and a magnetic conductor is used to adjust the distribution of magnetic field lines of the first magnetic pole and the second magnetic pole. When the first display screen and the second display screen are in an unfolded state, the magnetic conductor confines the magnetic field lines between the first magnetic pole and the second magnetic pole in the magnetic component, reducing the number of magnetic field lines radiated outward by the first magnetic pole and the second magnetic pole, thereby reducing the ability of the first magnetic pole and the second magnetic pole to adsorb foreign objects, and further reducing the probability of damage when the first display screen and the second display screen are in a folded state; when the first display screen and the second display screen are in a folded state, the magnetic conductor confines the magnetic field lines between the first magnetic pole in the magnetic component of the first display screen and the second magnetic pole in the magnetic component of the opposite second display screen, and between the second magnetic pole in the magnetic component of the first display screen and the first magnetic pole in the magnetic component of the opposite second display screen, improving the field strength between two relatively arranged magnetic components, so that the first display screen and the second display screen maintain close contact.

[0031] The present disclosure is not limited to the embodiments shown in the drawings, but includes modifications to the configurations formed based on the manufacturing process. Therefore, the regions illustrated in the drawings have schematic properties, and the shapes of the regions shown in the figures illustrate the specific shapes of the regions of the components, but are not intended to be restrictive.

[0032] In some related technologies, a first magnet is provided on a first display screen, and a second magnet is provided on a second display screen. When the first display screen and the second display screen are in an unfolded state, since the magnetic field lines of the first magnet and the second magnet are perpendicular to the first display screen and the second display screen respectively, a relatively large magnetic field exists on the surfaces of the first display screen and the second display screen. This magnetic field easily adsorbs magnetic foreign objects on the surfaces of the first display screen and the second display screen. When the first display screen and the second display screen are in a folded state, foreign objects with spikes are likely to pierce the surfaces of the first display screen and the second display screen, causing damage to the first display screen and the second display screen.

[0033] In a first aspect, embodiments of the present disclosure provide a display screen that can reduce the damage caused by magnetic foreign objects to the display screen.

[0034] Figure 1 It is a schematic structural diagram of a display screen provided by an embodiment of the present disclosure. Figure 3 It is a schematic structural diagram of a magnetic component provided by an embodiment of the present disclosure. The arrowed line segments in the figure indicate the directions of the magnetic field lines. As Figure 1 and Figure 3 shown, the display screen provided by the embodiments of the present disclosure includes a first display screen 1, a second display screen 2, and a magnetic component 5. When the display screen is in a folded state, the first display screen 1 and the second display screen 2 are stacked together. When the first display screen 1 and the second display screen 2 are folded, the display surfaces of the first display screen 1 and the second display screen 2 face each other.

[0035] In some embodiments, the first display screen 1 and the second display screen 2 are flexible screens or other screens capable of realizing a display function.

[0036] In some embodiments, the first display screen 1 and the second display screen 2 are of an integral structure or a split structure. The embodiments of the present disclosure are introduced by taking the integral structure as an example.

[0037] In some embodiments, as Figure 1 and Figure 4 shown, at least one magnetic component 5 is respectively provided on the first display screen 1 and the second display screen 2. When the first display screen 1 and the second display screen 2 are in a folded state, the positions of the magnetic poles of the magnetic components 5 provided on the first display screen 1 and the second display screen 2 are opposite and the polarities are opposite to each other. Figure 4 The arrowed line segments in

[0038] AsFigure 2 As shown, when a plurality of magnetic components 5 are respectively arranged on the first display screen 1 and the second display screen 2, the plurality of magnetic components 5 can be arranged at intervals or closely arranged on the first display screen 1 and the second display screen 2. Moreover, the positions of the plurality of magnetic components 5 arranged on the first display screen 1 and the plurality of magnetic components 5 arranged on the second display screen 2 correspond one by one.

[0039] As Figure 1 and Figure 4 shown, in order to ensure that the first display screen 1 and the second display screen 2 remain in the folded state for a long time, the magnetic components 5 can be arranged at one end of the first display screen 1 and the second display screen 2 far from the rotation axis. Among them, the rotation axis is the rotation axis during the folding and unfolding process of the first display screen 1 and the second display screen 2.

[0040] In some embodiments, the magnetic component 5 includes a first magnetic pole 51, a second magnetic pole 52, a connecting portion 53 connecting the first magnetic pole 51 and the second magnetic pole 52, and a magnetic conductor 54. The first magnetic pole 51, the second magnetic pole 52, and the connecting portion 53 form a U-shaped structure, and the polarities of the first magnetic pole 51 and the second magnetic pole 52 are opposite.

[0041] In some embodiments, the materials of the first magnetic pole 51, the second magnetic pole 52, and the connecting portion 52 are all magnetic materials, such as made of magnets or other materials that can generate magnetic attraction.

[0042] The embodiments of the present disclosure do not limit the polarities of the first magnetic pole 51 and the second magnetic pole 52. For example, the first magnetic pole 51 is an N pole, the second magnetic pole 52 is an S pole, or the first magnetic pole 51 is an S pole, and the second magnetic pole 52 is an N pole.

[0043] In some embodiments, the connecting portion 53 includes a magnetic thin sheet, that is, in the thickness direction of the display screen, the thickness of the connecting portion 53 is less than the thicknesses of the first magnetic pole 51 and the second magnetic pole 52. This can reduce the overall thickness of the magnetic component 5, and the magnetic component can also be embedded in the first display screen 1 or the second display screen 2 when the thickness of the display screen is limited.

[0044] In the embodiments of the present disclosure, as Figure 1 and Figure 4 shown, the first magnetic pole 51 and the second magnetic pole 52 in the magnetic component 5 arranged on the first display screen 1 are arranged on the side close to the second display screen 2, that is, the first magnetic pole 51 and the second magnetic pole 52 in the magnetic component 5 arranged on the first display screen 1 are arranged facing the second display screen 2, and the connecting portion 53 is arranged away from the second display screen 2. The magnetic conductor 54 is stacked on one end of the first magnetic pole 51 and the second magnetic pole 52 close to the second display screen 2.

[0045] In the embodiments of the present disclosure, the first magnetic pole 51 and the second magnetic pole 52 in the magnetic assembly 5 provided on the second display screen 2 are provided on the side close to the first display screen 1, that is, the first magnetic pole 51 and the second magnetic pole 52 in the magnetic assembly 5 provided on the second display screen 2 are arranged facing the first display screen 1, and the connecting portion 53 is arranged away from the first display screen 1. The magnetic conductor 54 in the magnetic assembly 5 provided on the second display screen 2 is stacked on one end of the first magnetic pole 51 and the second magnetic pole 52 close to the first display screen 1.

[0046] In the embodiments of the present disclosure, when the magnetic conductor 54 is provided at the ends of the first magnetic pole 51 and the second magnetic pole 52, the magnetic conductor 54 can constrain the magnetic field lines of the first magnetic pole 51 and the second magnetic pole 52.

[0047] Figure 5 FIG. is a schematic diagram of the distribution of magnetic field lines when no magnetic conductor is provided at the ends of the first magnetic pole and the second magnetic pole, where the arrowed line segment is the direction of the magnetic field line. As Figure 5 shown, assuming that the first magnetic pole 51 is an N pole and the second magnetic pole 52 is an S pole, when no magnetic conductor 54 is provided at the ends of the first magnetic pole 51 and the second magnetic pole 52, the magnetic field lines at the end of the first magnetic pole 51 diverge outward, and the magnetic field lines at the end of the second magnetic pole 52 converge from the outside to the inside, that is, the magnetic field lines of the first magnetic pole 51 and the second magnetic pole 52 leak out. Therefore, the first magnetic pole 51 and the second magnetic pole 52 are likely to adsorb magnetic substances.

[0048] As Figure 3 shown, assuming that the first magnetic pole 51 is an N pole and the second magnetic pole 52 is an S pole, when the magnetic conductor 54 is provided at the ends of the first magnetic pole 51 and the second magnetic pole 52, the magnetic field lines emitted by the first magnetic pole 51 are constrained within the magnetic conductor 54, reducing the leakage of the magnetic field lines of the first magnetic pole 51 and the second magnetic pole 52. When the first display screen 1 and the second display screen 2 are in the unfolded state, the magnetic conductor 54 constrains the magnetic field lines between the first magnetic pole 51 and the second magnetic pole 52 in the magnetic assembly 5.

[0049] As Figure 3 shown, assuming that the first magnetic pole 51 is an N pole and the second magnetic pole 52 is an S pole, inside the magnetic assembly, the magnetic field lines reach the first magnetic pole 51 from the second magnetic pole 52 through the connecting portion 53. Outside the magnetic assembly, the magnetic field lines reach the second magnetic pole 52 from the first magnetic pole 51 through the magnetic conductor 54. Since the magnetic conductor 54 is provided at the ends of the first magnetic pole 51 and the second magnetic pole 52, the magnetic field lines perpendicular to the ends of the first magnetic pole 51 and the second magnetic pole 52 are basically constrained within the magnetic conductor 54, reducing the probability of the first magnetic pole 51 and the second magnetic pole 52 adsorbing magnetic foreign objects.

[0050] When the first display screen 1 and the second display screen 2 are in the folded state, the magnetic conductor 54 confines the magnetic field lines between the first magnetic pole 51 in the magnetic assembly 5 of the first display screen 1 and the second magnetic pole 52 in the magnetic assembly 5 of the opposite second display screen 2, and confines the magnetic field lines between the second magnetic pole 52 in the magnetic assembly 5 of the first display screen 1 and the first magnetic pole 51 in the magnetic assembly 5 of the opposite second display screen 2. Therefore, the magnitude of the magnetic force exerted by the magnetic assembly 5 on the outside varies with the unfolded state and the folded state. When the first display screen 1 and the second display screen 2 are in the folded state, the magnetic force exerted by the magnetic assembly 5 on the outside is relatively large, which can ensure that the first display screen 1 and the second display screen 2 always remain in the folded state. When the first display screen 1 and the second display screen 2 are in the unfolded state, the magnetic force exerted by the magnetic assembly 5 on the outside is relatively small, reducing the probability that magnetic foreign objects are adsorbed on the surfaces of the first display screen 1 and the second display screen 2.

[0051] As Figure 4 shown, for the convenience of description, the magnetic assembly provided on the first display screen 1 is referred to as the first magnetic assembly 5a, and the magnetic assembly provided on the second display screen 2 is referred to as the second magnetic assembly 5b. When the first display screen 1 and the second display screen 2 are in the folded state, the magnetic conductor 54 in the first magnetic assembly 5a confines the magnetic field lines between the first magnetic pole 51 in the first magnetic assembly 5a and the second magnetic pole 52 in the second magnetic assembly 5b, and confines the magnetic field lines between the second magnetic pole 52 in the first magnetic assembly 5a and the first magnetic pole 51 in the second magnetic assembly 5b.

[0052] For the display screen provided by the embodiments of the present disclosure, the connecting portion connects the first magnetic pole and the second magnetic pole, and uses the magnetic conductor to adjust the distribution of the magnetic field lines of the first magnetic pole and the second magnetic pole. When the first display screen and the second display screen are in the unfolded state, the magnetic conductor confines the magnetic field lines between the first magnetic pole and the second magnetic pole in the magnetic assembly, reducing the magnetic field lines radiated outward by the first magnetic pole and the second magnetic pole, thereby reducing the ability of the first magnetic pole and the second magnetic pole to adsorb foreign objects, and further reducing the probability of damage when the first display screen and the second display screen are in the folded state; when the first display screen and the second display screen are in the folded state, the magnetic conductor confines the magnetic field lines between the first magnetic pole in the magnetic assembly of the first display screen and the second magnetic pole in the magnetic assembly of the opposite second display screen, and confines the magnetic field lines between the second magnetic pole in the magnetic assembly of the first display screen and the first magnetic pole in the magnetic assembly of the opposite second display screen, increasing the field strength between the two relatively arranged magnetic assemblies, so that the first display screen and the second display screen maintain close contact.

[0053] In some embodiments, as Figure 4 and Figure 6As shown, the magnetic conductor 54 includes a cavity 541 and a ferrofluid 542. The ferrofluid 542 is disposed within the cavity 541 and flows within the cavity 541 under the action of the first magnetic pole 51 and the second magnetic pole 52. The ferrofluid 542 has both the fluidity of a liquid and the magnetism of a solid magnetic material, just like a flowing "magnet". The ferrofluid 542 includes magnetic particles, a base carrier liquid (liquid medium), and a surfactant. In other words, the ferrofluid 542 is a special material formed by dispersing magnetic particles in the base carrier liquid. The magnetic particles are usually made of materials such as ferrite, nickel, or cobalt. When an external magnetic field is applied, these magnetic particles will be arranged in an orderly manner according to the direction of the magnetic field, causing the entire ferrofluid to exhibit the behavior of a magnetic solid.

[0054] In some embodiments, the cavity 541 includes a first cavity 541a, a second cavity 541b, and a connection channel 541c connecting the first cavity 541a and the second cavity 541b. The connection channel 541c communicates the first cavity 541a and the second cavity 541b, and the ferrofluid 542 can flow freely in the first cavity 541a, the second cavity 541b, and the connection channel 541c. When there are magnetic fields at the positions of the first cavity 541a and the second cavity 541b, the ferrofluid 542 accumulates towards the first cavity 541a and the second cavity 541b, which can increase the magnetic field strength at the positions of the first cavity 541a and the second cavity 541b.

[0055] In some embodiments, the cross-sectional area of the connection channel 541c in the flow direction is smaller than the projected areas of the first cavity 541a and the second cavity 541b on the display screen, forming a cavity 541 that is large at both ends and small (narrow) in the middle. Herein, the flow direction of the connection channel 541c refers to the direction connecting the first cavity 541a and the second cavity 541b, and can also be understood as the length direction of the connection channel 541c. The smaller cross-sectional area of the connection channel 541c in the flow direction helps to reduce the magnetic field lines within the connection channel 541c, causing the magnetic field lines to accumulate at the positions of the first cavity 541a and the second cavity 541b, thereby increasing the magnetic field strength at the positions of the first cavity 541a and the second cavity 541b.

[0056] In some embodiments, the projected area of the first cavity 541a on the first display screen 1 is greater than, equal to, or less than the projected area of the first magnetic pole 51 on the first display screen 1, and the projected area of the second cavity 541b on the first display screen 1 is greater than, equal to, or less than the projected area of the second magnetic pole 52 on the display screen. When the projected area of the first cavity 541a on the first display screen 1 is greater than the projected area of the first magnetic pole 51 on the first display screen 1, and the projected area of the second cavity 541b on the first display screen 1 is greater than the projected area of the second magnetic pole 52 on the display screen, in the case where the display screen is in a folded state, more magnetic fluid 542 can be gathered in the first cavity 541a and the second cavity 541b, increasing the density of magnetic field lines, thereby increasing the magnetic field strength at the positions of the first cavity 541a and the second cavity 541b.

[0057] In some embodiments, the shape of the projections of the first cavity 541a and the second cavity 541b on the first display screen 1 is one or more of a circle, a square, and a rhombus. Figure 6 In (a) is a top view, and in (b) is a side view. Figure 6 In the shown magnetic component, the shape of the projections of the first cavity and the second cavity on the first display screen 1 is a square. Figure 7 This is a schematic structural diagram of another magnetic conductor in an embodiment of the present disclosure, where (a) is a top view and (b) is a side view. Figure 6 In the shown magnetic component, the shape of the projections of the first cavity and the second cavity on the first display screen 1 is a circle.

[0058] In some embodiments, the material of the cavity includes a rigid material and a flexible material. Among them, the rigid material includes, but is not limited to, metal materials such as ferrite, and the flexible material includes, but is not limited to, plastics, rubbers, etc. The cavity made of the rigid material is a rigid cavity, and the cavity made of the flexible material is a flexible cavity. When the magnetic component 5 is disposed in the first display screen 1 and the second display screen 2, the flexible cavity can increase the deformation ability of the magnetic component 5, improve the adaptability of the magnetic component 5, thereby increasing the adaptation range of the display screen.

[0059] In some embodiments, the distance between the first magnetic pole 51 and the second magnetic pole 52 of any one magnetic component 5 is greater than the distance between the first magnetic pole 51 of the magnetic component disposed in the first display screen 1 and the second magnetic pole 52 of the opposite magnetic component disposed in the second display screen 2, and is also greater than the distance between the second magnetic pole 52 of the magnetic component disposed in the first display screen 1 and the first magnetic pole 51 of the opposite magnetic component disposed in the second display screen 2.

[0060] Such as Figure 4As shown, the distance h1 between the first magnetic pole 51 and the second magnetic pole 52 in the first magnetic component 5a is greater than the distance h2 between the first magnetic pole 51 in the first magnetic component 5a and the second magnetic pole 52 in the second magnetic component 5b, and the distance h2 between the second magnetic pole 52 in the first magnetic component 5a and the first magnetic pole 51 in the second magnetic component 5b.

[0061] It should be noted that the distance h2 herein refers to the distance between the first magnetic pole 51 in the first magnetic component 5a and the second magnetic pole 52 in the second magnetic component 5b, and the distance between the second magnetic pole 52 in the first magnetic component 5a and the first magnetic pole 51 in the second magnetic component 5b when the first display screen 1 and the second display screen 2 are in the folded state.

[0062] To reduce the influence of the magnetic component 5 on the display screens of the first display screen 1 and the second display screen 2, in the embodiments of the present disclosure, the magnetic component 5 can be arranged on the back of the first display screen 1 and the second display screen 2, that is, when the first display screen 1 and the second display screen 2 face the user, the magnetic component 5 is arranged on the side away from the user, and the first magnetic pole 51 and the second magnetic pole 52 face the first display screen 1 and the second display screen 2, and the connecting portion 53 is away from the first display screen 1 and the second display screen 2.

[0063] In some embodiments, the lengths of the first magnetic pole 51 and the second magnetic pole 52 in the thickness direction of the display screen are the same or different.

[0064] As Figure 8 shown, in the thickness direction of the display screen, the lengths of the first magnetic pole 51 and the second magnetic pole 52 are the same.

[0065] As Figure 9 shown, in the thickness direction of the display screen, the lengths of the first magnetic pole 51 and the second magnetic pole 52 are different. The outer dimensions of the first magnetic pole 51 and the second magnetic pole 52 can be determined according to the space reserved in the display screen. When the reserved space is large,

[0066] It should be noted that Figure 8 and Figure 9 the arrowed line segments in

[0067] In some embodiments, the specific lengths of the first magnetic pole 51 and the second magnetic pole 52 in the thickness direction of the display screen can be determined according to the space of the display screen, and the embodiments of the present disclosure do not limit this.

[0068] In a second aspect, the embodiments of the present disclosure provide an electronic device.

[0069] Figure 10 The structural schematic diagram of an electronic device provided by the embodiments of the present disclosure is shown. As Figure 10As shown, an electronic device provided by an embodiment of the present disclosure includes a display screen 10. The display screen 10 includes the display screen provided by the embodiment of the present disclosure. For the sake of saving space, it will not be elaborated here.

[0070] For the electronic device provided by the embodiment of the present disclosure, the display screen includes a first display screen, a second display screen, and a magnetic component. Among them, the connecting portion in the magnetic component connects the first magnetic pole and the second magnetic pole, and a magnetic conductor is used to adjust the magnetic field lines of the first magnetic pole and the second magnetic pole. When the first display screen and the second display screen are in the unfolded state, the magnetic conductor confines the magnetic field lines between the first magnetic pole and the second magnetic pole in the magnetic component, reducing the number of magnetic field lines radiated outward by the first magnetic pole and the second magnetic pole, thereby reducing the ability of the first magnetic pole and the second magnetic pole to adsorb foreign objects, and further reducing the probability of damage when the first display screen and the second display screen are in the folded state, thus improving the service life of the electronic device; the polarities of the first magnetic pole and the second magnetic pole are opposite. When the first display screen and the second display screen are in the folded state, the magnetic conductor confines the magnetic field lines between the first magnetic pole in the magnetic component and the second magnetic pole in the opposite magnetic component, and between the second magnetic pole in the magnetic component and the first magnetic pole in the opposite magnetic component, increasing the field strength between the two relatively arranged magnetic components, so that the first display screen and the second display screen maintain close contact.

[0071] The present disclosure has disclosed exemplary embodiments, and although specific terms are used, they are used only and should be construed only as general illustrative meanings and not for the purpose of limitation. In some instances, it will be apparent to those skilled in the art that, unless otherwise expressly stated, the features, characteristics, and / or elements described in connection with a particular embodiment may be used alone or in combination with the features, characteristics, and / or elements described in connection with other embodiments. Accordingly, those skilled in the art will understand that various changes in form and detail may be made without departing from the scope of the present disclosure as set forth by the appended claims.
