This application is capable of embodiments in many different forms than those described herein and that modifications may be made by one skilled in the art without departing from the spirit and scope of the application and it is therefore not intended to be limited to the specific embodiments disclosed below.
In the description of the present application, it is to be understood that the terms "central," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," and the like are used in the orientations and positional relationships indicated in the drawings for convenience in describing the present application and to simplify the description, but are not intended to indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, and are not to be construed as limiting the present application.

The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as the case may be.
In this application, unless expressly stated or limited otherwise, a first feature is "on" or "under" a second feature such that the first and second features are in direct contact, or the first and second features are in indirect contact via an intermediary. Also, a first feature "on," "above," and "over" a second feature may be directly on or obliquely above the second feature, or simply mean that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

In the display field, in order to meet the requirement of a user on a large-size display screen, a sliding screen, a folding screen, and the like based on an Organic Light Emitting Diode (OLED) flexible display panel are developed, so that the portability of the display screen is ensured while the size of the display screen is increased.
However, the inventor of the present application has found that the OLED display panel has a problem of large thickness due to its structural characteristics. Specifically, the overall thickness of a Liquid Crystal Display panel (LCD) is 2.845mm, the overall thickness of an Active Matrix Organic Light Emitting Diode (AMOLED) is 1.896mm, the overall thickness of a plastic AMOLED is 0.98mm, and the overall thickness of a Micro Light Emitting Diode (Micro LED) is 0.15mm. The thickness of the AMOLED is reduced by 30% compared with that of the LCD, and the Plastic AMOLED uses Polyimide (PI) instead of the glass substrate, so that the thickness of the Plastic AMOLED is reduced by 70% compared with that of the LCD, while the Micro LED has a simple composition structure, and generally only includes a substrate and LEDs stacked on the substrate, so that the thickness of the Micro LED is reduced by 95% compared with that of the LCD.
Based on this, the inventor of the present application proposes an inventive concept, by making the Micro LED display panel into a display panel with flexibility, a display panel with a small thickness and a large screen size can be obtained, and meanwhile, due to the flexible characteristic, the portability can be improved by curling, folding and the like.
Fig. 1 shows a schematic structural diagram of a display panel in an embodiment of the present application. Fig. 2 is a top view illustrating a partial structure of a display panel according to an embodiment of the present application. Fig. 3 showsbase:Sub>A schematic sectional view along the directionbase:Sub>A-base:Sub>A in fig. 2.
Referring to fig. 1 to 3, a display panel 1 according to an embodiment of the present disclosure includes a substrate 10, a plurality of LED light emitting elements 20, and a deformation element 30. The substrate 10 has a first rolled state and a first rolled state, and the substrate 10 may specifically be an LED Light bar (Light bar), such as a Flexible Printed Circuit (FPC), a Flexible Flat Cable (FFC), or a Printed Circuit Board (PCB). When the substrate 10 is made of a hard plate material, a plurality of small substrates 10 made of a hard plate material may be combined to form the substrate 10 having a desired size by using, for example, a wrist-watch wrist-band connection method, so that the obtained substrate 10 can have flexibility, and the substrate 10 can be adjusted to the first rolled state as needed. A plurality of LED light emitting elements 20 are arranged on the surface of the substrate 10, and the LED light emitting elements 20 are Micro LEDs for example, so as to obtain a better display effect. The deforming assembly 30 is provided on the substrate 10, and the deforming assembly 30 is configured for switching the substrate 10 between a first curled state and a first unfolded state. Wherein the plurality of LED light emitting elements 20 may be arranged in a row and in a column, respectively, in two directions crossing each other on the substrate 10. For example, for a substrate 10 formed by combining a plurality of small substrates 10, a plurality of LED light emitting elements 20 may be arrayed on each small substrate 10, respectively; for a substrate 10 formed of an integral piece of flexible sheet material, a plurality of LED light emitting elements 20 may be arrayed on the substrate 10; a plurality of sub-regions 11 may also be divided on the substrate 10, the LED light emitting elements 20 in each sub-region 11 are arranged in an array, and a gap exists between two adjacent sub-regions 11, so as to ensure that the LED light emitting elements 20 in two adjacent regions do not interfere with each other in the process of switching the substrate 10 between the first rolled state and the first rolled state.
Based on this, by providing the deforming member 30 on the substrate 10, the substrate 10 can be switched between the first rolled state and the first unrolled state by the deforming member 30. When a user needs to use the display panel 1, the substrate 10 may be switched to the first unfolded state, and the LED light emitting elements 20 arranged on the surface of the substrate 10 provide light sources for the display panel 1, so as to meet the user requirements; when a user needs to carry the display panel 1, the substrate 10 can be switched to the first rolled state, thereby improving its portability.
In some embodiments, the deformation element 30 includes a layer of piezoelectric material or a layer of memory metal that is attached to the substrate 10 or at least partially embedded within the substrate 10. The substrate 10 is switched between a first curled state and a first unfolded state by utilizing the characteristic that the piezoelectric material can generate mechanical deformation under the action of an electric field; or the memory metal material can recover the original macroscopic shape in another temperature range after being subjected to plastic deformation in a certain temperature range, so that the substrate 10 is switched between the first coiling state and the first unfolding state.
Fig. 4 is a schematic diagram illustrating a partial structure of a display panel according to an embodiment of the present application.
Referring to fig. 3 and 4, in other embodiments, the deformation assembly 30 includes a first magnetic attraction layer and a second magnetic attraction layer that can attract the first magnetic attraction layer; the first magnetic layer comprises a plurality of first magnetic pieces 31 arranged on the substrate 10 at intervals, and the second magnetic layer comprises a plurality of second magnetic pieces 32 arranged on one side of the substrate 10 at intervals; the orthographic projection of the plurality of first magnetic pieces 31 on the surface of the substrate 10 is partially overlapped with the orthographic projection of the plurality of second magnetic pieces 32 on the surface of the substrate 10, and the orthographic projection of the plurality of second magnetic pieces 32 on the surface of the substrate 10 covers the gaps between the orthographic projections of the plurality of first magnetic pieces 31 on the surface of the substrate 10; one of the first magnetic member 31 and the second magnetic member 32 is an electromagnet, and the other is a permanent magnet. Accordingly, the electromagnet is energized to generate magnetism, so that the first magnetic member 31 and the second magnetic member 32 can generate magnetic force attracting each other; meanwhile, the orthographic projections of the plurality of first magnetic members 31 on the surface of the substrate 10 are partially overlapped with the orthographic projections of the plurality of second magnetic members 32 on the surface of the substrate 10, and the orthographic projections of the plurality of second magnetic members 32 on the surface of the substrate 10 cover gaps between the orthographic projections of the plurality of first magnetic members 31 on the surface of the substrate 10, so that after the first magnetic attraction layer and the second magnetic attraction layer are attracted with each other, the formed laminated structure is rigid. After the electromagnet is stopped to be electrified, the attraction force between the second magnetic attraction layer and the first magnetic attraction layer is removed, and the plurality of first magnetic pieces 31 on the substrate 10 are arranged at intervals, so that the substrate 10 can be deformed at the gap between the adjacent first magnetic pieces 31, and the flexible state is represented. In this way, the substrate 10 can be rendered rigid by energizing the electromagnets, and the substrate 10 can be rendered flexible by de-energizing the electromagnets, thereby enabling a user to maintain the substrate 10 in the first rolled state or the first unrolled state as desired for use.
Optionally, a filling layer is disposed in a gap between adjacent second magnetic members 32, and the filling layer may be specifically an adhesive layer, so as to limit the plurality of second magnetic members 32, and enable the plurality of second magnetic members 32 to be orderly arranged.
Exemplarily, the orthographic projections of the plurality of first magnetic members 31 on the surface of the substrate 10 are respectively arranged in a row and a column along two mutually intersecting directions, two adjacent rows of the first magnetic members 31 are arranged in a staggered manner, and two adjacent columns of the first magnetic members 31 are arranged in a staggered manner; the orthographic projections of the plurality of second magnetic members 32 on the surface of the substrate 10 are respectively arranged in rows and columns along two mutually-crossed directions, two adjacent rows of second magnetic members 32 are arranged in a staggered manner, and two adjacent columns of second magnetic members 32 are arranged in a staggered manner; meanwhile, the orthographic projection of the plurality of first magnetic members 31 on the surface of the substrate 10 partially overlaps with the orthographic projection of the plurality of second magnetic members 32 on the surface of the substrate 10, and the orthographic projection of the plurality of second magnetic members 32 on the surface of the substrate 10 covers the gap between the orthographic projections of the plurality of first magnetic members 31 on the surface of the substrate 10. In this way, when the electromagnet is energized, the respective regions of the first and second magnetic attraction layers can be attracted uniformly, thereby ensuring the flatness of the substrate 10 in the first unfolded state. The two mutually crossed directions comprise two mutually perpendicular directions, two directions with acute included angles and two directions with obtuse included angles.
Illustratively, the ratio of the arrangement density of the plurality of LED light emitting elements 20 to the arrangement density of the plurality of first magnetic members 31 is 1. In other embodiments, the coverage area of the LED light emitting element 20 on the substrate 10 may be further set to be greater than 66.7% to obtain better display effect.
In some embodiments, the plurality of first magnetic members 31 are attached to the surface of the substrate 10 or at least partially embedded in the substrate 10, and the plurality of second magnetic members 32 are disposed on one side of the substrate 10. Because one of the first magnetic member 31 and the second magnetic member 32 is an electromagnet, in order to prevent the electromagnet from short-circuiting with the metal trace on the substrate 10, it is preferable that the electromagnet is disposed on a surface of the substrate 10 away from the metal trace or embedded in the substrate 10, so that the electromagnet is insulated from the metal trace on the substrate 10.

Fig. 6 is a schematic structural diagram illustrating a protective cover layer of a display panel in a second unfolded state according to an embodiment of the present application.
Referring to fig. 5 and 6, in some embodiments, the display panel 1 further includes a protective shell layer 40, and the protective shell layer 40 has a second rolled state and a second unrolled state; in the second curled state, the protective shell layer 40 forms a cylindrical structure for accommodating the combined structure of the substrate 10, the plurality of LED light emitting elements 20 and the deformation component 30 in the first curled state; in the second unfolded state, the protective cover 40 forms a flat plate structure for supporting the combined structure of the substrate 10, the plurality of LED light emitting elements 20, and the deformable member 30 in the first unfolded state. In this way, when the substrate 10 is in the first curled state, the cylindrical structure formed by the protective shell layer 40 can protect the combined structure of the substrate 10, the plurality of LED light-emitting elements 20 and the deformation assembly 30, so that the display panel 1 can be reduced in risk of damage while being convenient to carry; when the substrate 10 is in the first unfolded state, the protective shell 40 of the flat plate structure can support the combined structure of the substrate 10, the plurality of LED light-emitting elements 20 and the deformation component 30, so that the display panel 1 has better flatness and higher rigidity after being unfolded.
Optionally, the protective shell layer 40 includes a magnetic layer, and the magnetic layer includes a plurality of magnetic blocks 42 arranged at intervals; in the second unfolded state, the orthographic projections of the plurality of magnetic blocks 42 on the surface of the substrate 10 partially overlap with the orthographic projections of the plurality of second magnetic members 32 on the surface of the substrate 10, and the orthographic projections of the plurality of magnetic blocks 42 on the surface of the substrate 10 cover gaps between the orthographic projections of the plurality of second magnetic members 32 on the surface of the substrate 10. The magnetic block 42 may be an electromagnet or a permanent magnet. The interaction principle between the magnetic layer and the second magnetically attractive layer may refer to the interaction principle between the second magnetically attractive layer and the first magnetically attractive layer. In this manner, switching of the protective shell layer 40 between the second rolled state and the second unrolled state is achieved.
Optionally, the protective shell 40 includes a protective layer 41 and a magnetic layer, and the magnetic layer is disposed on the surface of the protective layer 41 or embedded in the protective layer 41. When the magnetic layer is disposed on the surface of the protection layer 41, the magnetic layer and the protection layer 41 are fixed to each other or can be separated from each other, and the material of the magnetic layer may be a metal capable of being attracted by magnetic force, an electromagnet with magnetic force after being energized, or a silica gel (i.e., a silica gel) containing a metal or an electromagnet therein. Illustratively, the protective shell layer 40 has a thickness of 0.05mm to 0.75mm.
In some embodiments, the protective shell 40 includes a protective layer 41 and a magnetic layer disposed on the protective layer 41, and the magnetic layer forms a second magnetically attractive layer, so that the protective shell 40 can serve as both a protective function and an unfolding support function.
In some embodiments, the substrate 10 comprises a flexible substrate layer. Illustratively, the Flexible substrate layer is a Flexible Printed Circuit (FPC) or a Flexible Flat Cable (FFC). In this way, when the deformation assembly 30 removes the rigid support for the substrate 10, the substrate 10 can be flexibly curled, thereby improving portability.

In other embodiments, the substrate 10 includes a plurality of rigid portions, the plurality of rigid portions are arranged in a row along a first direction, arranged in a column along a second direction, and any two adjacent rigid portions of the plurality of rigid portions arranged in a row along the first direction are connected by a hinge; wherein the first direction intersects the second direction.

Based on this, even when the deformation unit 30 removes the rigid support for the substrate 10, the substrate 10 can be flexibly curled, thereby improving the portability thereof.

Optionally, the shape of the convex portion is a triangle, a quadrangle, a pentagon, a semicircle or a combination of at least two thereof.
