Description

Technical Field

[0001] This application relates to the field of display device technology, and in particular to a display screen structure and display device. Background Technology

[0002] Traditional screen display electronic products, such as laptops, tablets, and smartphones, have the following drawbacks: fixed screen size that cannot be adjusted according to user needs; poor portability, especially when the screen size is large, making them heavy or uncomfortable to carry; and limited scalability, making it difficult for users to upgrade the required functions by replacing the screen or other components in certain situations. Summary of the Invention

[0003] In view of this, it is necessary to provide a display screen structure in order to solve at least one of the above technical problems.

[0004] In addition, this application also needs to provide a display device that uses the above-described display screen structure.

[0005] In a first aspect, this application provides a display screen structure, including: a support component, a plurality of first telescopic components, and a flexible display component. The support component has a first surface and is extendable or retractable along a first direction, where the first direction is an extension direction of the first surface. A plurality of first telescopic components are spaced apart on one side of the support component along the first direction, and each first telescopic component is extendable or retractable along a second direction perpendicular to the first surface. The flexible display component is located on the first surface and extends to the side of the support component away from the first surface, bypassing the plurality of first telescopic components. The display screen structure can be in an unfolded state and a retracted state. In the unfolded state, the support component extends along the first direction, and the plurality of first telescopic components retract along the second direction, thereby increasing the length of the flexible display component on the first surface and decreasing the length bypassing the first telescopic components. In the retracted state, the support component retracts along the first direction, and a plurality of first telescopic components extend along the second direction, thereby decreasing the length of the flexible display component on the first surface and increasing the length bypassing the first telescopic components.

[0006] Secondly, embodiments of this application also provide a display device, including the display screen structure and circuit board described above. The circuit board is located on the side of the first telescopic component away from the support component. The circuit board has a groove corresponding to each of the first telescopic components, and a support wall is provided between two adjacent grooves. The flexible display component is electrically connected to the circuit board, and the first telescopic component can extend into or retract from the groove along the second direction.

[0007] The display device provided in this application embodiment, by employing a stretchable display screen structure, offers greater flexibility and elastic expansion capabilities. The screen size can be adjusted as needed, making it suitable for various scenarios. Because the display screen structure can extend and retract, it is highly portable, effectively improving the user experience. Furthermore, since the display screen structure can freely extend and bend, it can be easily converted into different usage modes. Additionally, the lighting and shutdown of different display areas can be independently controlled during use; unused areas can be turned off, resulting in greater energy savings.

[0055] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0056] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0057] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. When a component is said to be "set on" another component, it can be directly set on the other component or there may be an intervening component.

[0058] Please see Figure 1 and Figure 2 As shown, this application provides a display device 100, which includes a display screen structure 10 and a circuit board 20. Specifically, the display screen structure 10 includes at least one support component 1, a plurality of first telescopic components 2, and a flexible display component 3. The support component 1 has a first surface 101, and the support component 1 can extend or retract along a first direction X, where the first direction X is an extension direction of the first surface 101. The plurality of first telescopic components 2 are spaced apart along the first direction X on the side of the support component 1 away from the first surface 101, and each of the first telescopic components 2 can extend or retract along a second direction Y perpendicular to the first surface 101. The flexible display component 3 is located on the first surface 101 and can extend to the side of the support component 1 away from the first surface 101 and bypass the plurality of first telescopic components 2. The display screen structure 10 is disposed on the surface of the circuit board 20, and the flexible display component 3 is electrically connected to the circuit board 20.

[0059] The display screen structure 10 can be in an unfolded state and a retracted state. For example... Figure 2 As shown, in the unfolded state, the support component 1 extends along the first direction X, and the plurality of first telescopic components 2 retract along the second direction Y, so that the length of the flexible display component 3 on the first surface 101 increases, and the length around the first telescopic components 2 decreases. Figure 1As shown, in the contracted state, the support component 1 retracts along the first direction X, and the plurality of first telescopic components 2 extend along the second direction Y, so that the length of the flexible display component 3 on the first surface 101 is reduced, and the length around the first telescopic components 2 is increased.

[0060] Please refer to both together. Figure 3 and Figure 4 As shown, the support assembly 1 includes a support body 11 and a first driving member 12. The support body 11 has the first surface 101, and the first driving member 12 is used to drive the support body 11 to extend or retract along the first direction X.

[0061] In some embodiments, the support body 11 includes a telescopic component 13 and a plurality of support members 14, the plurality of support members 14 being spaced apart on the telescopic component 13 along the first direction X. The first driving member 12 provides a driving force, and the telescopic component 13 can extend or retract along the first direction X under the action of the driving force. When the telescopic component 13 extends, the length of the first gap a between two adjacent support members 14 increases; when the telescopic component 13 retracts, the length of the first gap a decreases. Here, the telescopic component 13 can provide a supporting plane for the flexible display assembly 3 and can also realize the telescopic function, while the support members 14 can provide a supporting force for the flexible display assembly 3, reducing the deformation of the flexible display assembly 3 during telescopic or use.

[0062] The specific scaling process is as follows: Figure 3 As shown, the first driving member 12 can provide driving force to the telescopic member 13. Under the action of the driving force, the telescopic member 13 can extend along the first direction X, thereby increasing the length of the first gap a between two adjacent support members 14 on the telescopic member 13, and realizing the extension of the support body 11. Figure 4 As shown, the first driving member 12 can also provide another driving force to the telescopic member 13. Under the action of this other driving force, the telescopic member 13 can retract along the first direction X, thereby shortening the length of the first gap a between two adjacent support members 14. It can be understood that the other driving force here can be 0, that is, when the elongation driving force is removed, the telescopic member 13 can automatically retract.

[0063] In some embodiments, the first driving member 12 may be disposed at at least one end of the retractable member 13. The first driving member 12 may be electrically connected to the circuit board 20, and the control of the first driving member 12 may be realized through the circuit board 20. It is understood that the control of the first driving member 12 may also be realized by setting a control circuit independently.

[0064] In some embodiments, the telescopic component 13 includes a telescopic piece 15 and a plurality of support portions 16, the plurality of support portions 16 being spaced apart along the first direction X on the telescopic piece 15. The telescopic piece 15 is made of a stretchable material. This stretchable material can deform under external force, causing its length to elongate, and can automatically return to its original shape after the external force is removed. When the driving force provided by the first driving member 12 is applied, the telescopic piece 15 is stretched along the first direction X, at which point the length of the second gap b between two adjacent support portions 16 increases; when the driving force is removed, the telescopic piece 15 returns to its original shape, its length shortens, at which point the length of the second gap b between two adjacent support portions 16 shortens. It is understood that the support portions 16 can also be made of a stretchable material, but the material should be harder than that of the telescopic piece 15 to provide better support; the support portions 16 may also not be made of a stretchable material.

[0065] In some embodiments, the first gap a and the second gap b are misaligned, which can further improve the support strength of the support body 11 after it is extended, and provide better support for the flexible display component 3.

[0066] Please refer to both together. Figures 5 to 7 As shown, the support body 11 has a first part 111 and a second part 112 connected to each other. In the unfolded state, the first part 111 is located on a plurality of first telescopic components 2. The second part 112 can be horizontal with the first part 111, or it can be bent relative to the first part 111 so that the second part 112 and the first part 111 form an angle, the angle being 0° to -180°, thereby realizing the bending function of the display screen structure 10. Specifically, the first part 111 and the second part 112 can be located on the same plane and be horizontal, such as... Figure 2 As shown; Figure 5 and Figure 6 As shown, when the second part 112 is bent relative to the first part 111 towards the side of the first telescopic component 2, the second part 112 can be attached to the side of the circuit board 20, realizing sidewall display, increasing the display area, and expanding application scenarios. Figure 6 The second part 112 can be further flattened; it can also be further bent so that part of the second part 112 is attached to the side of the circuit board 20, while the remaining part of the second part 112 is attached to the back of the circuit board 20, such as... Figure 7 As shown. Specifically, as can be seen from the structure of the aforementioned support body 11, there is a first gap a between two adjacent support members 14, which provides the support body 11 with the possibility of bending.

[0067] like Figure 1 and Figure 2As shown, the display structure 10 includes a support component 1, thereby enabling the display structure 10 to have a unidirectional telescopic function. Specifically, in the retracted state, the support component 1 includes a fixed end 102 and a free end 103 disposed opposite to each other. The free end 103 can move away from or towards the fixed end 102 in one direction. At this time, one end of the flexible display component 3 is fixed to the fixed end 102, and the other end bypasses the free end 103 and extends to the underside of the support component 1, bypassing all the first telescopic components 2, and is further electrically connected to the circuit board 20.

[0068] Please refer to it again. Figure 1 and Figure 2 As shown, the first telescopic component 2 includes a first telescopic portion 21 disposed near the support component 1, a second telescopic portion 22 disposed opposite to the first telescopic portion 21 along the second direction Y, a telescopic member 23 located between the first telescopic portion 21 and the second telescopic portion 22, and a second driving member 24. The second driving member 24 is used to drive the telescopic member 23, thereby causing the second telescopic portion 22 to extend or retract along the second direction Y. The flexible display component 3 is wrapped around the first telescopic component 2, and will contact the first telescopic portion 21 and the second telescopic portion 22, and can move relative to the first telescopic portion 21 and the second telescopic portion 22. When the telescopic member 23 extends and becomes longer, the length of the flexible display component 3 wrapped around the first telescopic component 2 can be increased, so that the flexible display component 3 can be stored. When the telescopic member 23 retracts and becomes shorter, the flexible display component 3 is lengthened under the drive of the support component 1, thereby shortening the flexible display component 3 wrapped around the telescopic member 23. In some embodiments, the second driving member 24 may be disposed at one end of the first telescopic portion 21.

[0069] In some embodiments, the outer surfaces of the first telescopic portion 21 and the second telescopic portion 22 are smooth and rounded, so that the flexible display component 3 experiences less resistance and smoother sliding when sliding around the first telescopic component 2, reducing damage to the flexible display component 3 caused by sliding. Specifically, the cross-sections of the first telescopic portion 21 and the second telescopic portion 22 can both be semi-circular or arc-shaped, giving the first telescopic portion 21 and the second telescopic portion 22 rounded surfaces. Further, the cross-sections of the first telescopic portion 21 and the second telescopic portion 22 can be semi-circular, so that after the telescopic member 23 retracts, the first telescopic portion 21 and the second telescopic portion 22 can form a circle, which on the one hand provides a smooth surface, and on the other hand better protects the internal telescopic member 23.

[0070] Specifically, the structure of the telescopic component 23 is basically the same as that of the support body 11. Please refer to the aforementioned details of the support body 11; further elaboration will not be repeated here. It is understood that the telescopic component 23 can also employ other telescopic structures (such as telescopic rods) to achieve the telescopic function of the first telescopic assembly 2.

[0071] In some embodiments, when the display structure 10 is in the aforementioned retracted state, a plurality of the first telescopic components 2 are arranged side by side and spaced apart along the first direction X. At this time, one end of the flexible display component 3 is fixed to the fixed end 102, and the other end extends around the free end 103 and between the support component 1 and the row of first telescopic components 2 to the fixed end 102, and then around the first telescopic components 2 near the fixed end 102, and further returns to the free end 103, so that all the first telescopic components 2 are enclosed inside the flexible display component 3.

[0072] Please refer to it again. Figure 1 and Figure 2 As shown, the flexible display assembly 3 includes a flexible display screen 4 and a flexible circuit board 5 electrically connected to the flexible display screen 4. The flexible display screen 4 and the flexible circuit board 5 are interconnected along the length of the flexible display assembly 3. The flexible display screen 4 is located on the first surface 101 and extends to the side of the support assembly 1 away from the first surface 101 (i.e., below the support assembly 1) and wraps around multiple sets of the first telescopic components 2. The flexible circuit board 5 is located below the support assembly 1 and is wound around the multiple sets of the first telescopic components 2.

[0073] The flexible display screen 4 includes a first end 41 and a second end 42 disposed opposite to each other. The first end 41 is fixed to the fixed end 102 of the support component 1, and the second end 42 extends beyond the free end 103 of the support component 1 to the underside of the support component 1 and bypasses a portion of the first telescopic component 2. The flexible circuit board 5 includes a third end 51 and a fourth end 52 disposed opposite to each other. The third end 51 is connected to the second end 42, and the fourth end 52 bypasses another portion of the first telescopic component 2 and is electrically connected to the side of the circuit board 20 near the free end 103.

[0074] In some embodiments, the connection method between the flexible display screen 4 and the flexible circuit board 5 includes, but is not limited to, ACF bonding, flip chip technology, hot bar bonding, etc.

[0075] The flexible display screen 4 comprises a flexible substrate, thin-film electronic devices, a driving circuit, and a protective layer. Specifically, the flexible substrate can be made of materials such as polyimide or polyester film, possessing flexibility and plasticity, allowing deformation without damaging the circuit structure. Thin-film electronic devices can be, for example, thin-film transistors or OLEDs (including but not limited to fluorescent OLEDs, phosphorescent OLEDs, and dual-layer or multi-layer stacked tandem OLEDs). These thin-film electronic devices offer good flexibility, low power consumption, and good stability, making them suitable for flexible substrate fabrication. The driving circuit needs to be designed to be flexible or stretchable to adapt to the deformation of the display screen, ensuring display quality and stability. Covering the surface of the flexible display screen 4 with a flexible protective layer increases its wear resistance and water resistance.

[0076] In some embodiments, the flexible display screen 4 includes a first portion 43 and a second portion 44 connected to each other, wherein, in the contracted state and the extended state, the first portion 43 is located on the first surface 101 of the support component 1; in the contracted state, the second portion 44 is located on the side of the support component 1 away from the first surface 101 and is wrapped around the first telescopic component 2; in the extended state, at least a portion of the second portion 44 is movable onto the first surface 101.

[0077] In some embodiments, the lighting and turning off of the first portion 43 and the second portion 44 are independently controlled. The flexible display screen 4 may have multiple driver ICs to enable the lighting and turning off of different areas of the screen. That is, when the screen is in the retracted state, the flexible display screen 4 below the support component 1 (i.e., below the support component 1) is turned off. When the screen is unfolded, the second portion 44, which was originally below the support component 1, moves above the support component 1 and the screen lights up.

[0078] Please participate again. Figure 1 and Figure 2 As shown, the display screen structure 10 also includes multiple sets of second telescopic components 6. The first telescopic component 2 and the second telescopic component 6 are alternately arranged. The flexible display component 3 simultaneously passes over the first telescopic component 2 and the second telescopic component 6, which can increase the winding length of the flexible display component 3 and thus expand the size of the screen after unfolding.

[0079] In some embodiments, when in the retracted state, multiple sets of the first telescopic components 2 are located in the same row, multiple sets of the second telescopic components 6 are located in the same row, and the first telescopic components 2 are close to the support component 1. At this time, the flexible display component 3 passes between a row of first telescopic components 2 and the support component 1, bypasses the first telescopic component 2 near the fixed end 102 of the support component 1, then passes between the first telescopic components 2 and the second telescopic components 6 and extends to the free end 103 of the support component 1, finally being fixed to the circuit board 20. At this time, the telescopic directions of the first telescopic components 2 and the second telescopic components 6 are opposite. For example, along the second direction Y, the first telescopic component 2 extends downwards, and the second telescopic component 6 extends upwards. In this case, the retracted length of the flexible display component 3 can be wrapped around the first telescopic components 2 and the second telescopic components 6, which can effectively increase the length that can accommodate the flexible display component 3, thereby increasing the size of the screen in the unfolded state.

[0080] It is understandable that the structure of the second telescopic component 6 is basically the same as that of the first telescopic component 2. Please refer to the foregoing for details, and we will not go into too much detail here.

[0081] Please participate again. Figure 1 and Figure 2 As shown, the circuit board 20 has a groove 7 for each of the first telescopic components 2, and a support wall 8 is provided between two adjacent grooves 7. The flexible display component 3 is electrically connected to the circuit board 20, and the first telescopic component 2 can extend into or out of the groove 7 along the second direction Y.

[0082] The circuit board 20 has multiple grooves 7, which provide space for the extension of the first telescopic component 2, thereby effectively reducing the overall volume of the display device 100. In addition, the width of the grooves 7 is greater than the outer diameter of the first telescopic component 2, so that the sidewalls of the grooves 7 can reduce damage to the surface of the flexible display component 3 during the extension and retraction of the first telescopic component 2.

[0083] When only the first telescopic component 2 is set, the flexible display component 3 needs to be stored in the retracted state. Each first telescopic component 2 pushes a part of the flexible display component 3 into the groove 7. At this time, the upper surface of the support wall 8 of the circuit board 20 can serve as the support part of the flexible display component 3, so that the flexible display component 3 can be repeatedly wound around multiple first telescopic components 2 and multiple support walls 8, effectively extending the length of the flexible display component 3 stored.

[0084] When the first telescopic component 2 and the second telescopic component 6 are provided, each second telescopic component 6 is disposed on a support wall 8. In this case, as mentioned above, a longer flexible display component 3 can be accommodated. Furthermore, the smooth surface of the second telescopic component 6 helps to further reduce surface damage to the flexible display component 3. In some embodiments, one or more connecting pads 81 can be provided on the support wall 8, and the second telescopic component 6 can be attached to the connecting pad 81. Specific connection methods include, but are not limited to, ACF crimping, flip chip, hot bar, etc.

[0085] The circuit board 20 also includes a connecting pad 9, on which the flexible display component 3 is connected. In some embodiments, the connecting pad 9 is located on the side of the circuit board 20 near the free end 103 of the support component 1. In this case, one end of the flexible display component 3 is fixed to the fixed end 102, and the other end extends around the free end 103 to the underside of the support component 1, and passes around all the first telescopic components 2, passing between the first telescopic components 2 and the second telescopic components 6, and is further electrically connected to the connecting pad 9 on the circuit board 20. In some embodiments, the fourth end 52 of the flexible circuit board 5 in the flexible display component 3 is electrically connected to the connecting pad 9, and the specific connection method includes, but is not limited to, ACF crimping, flip chip, hot bar, etc. In addition, in order to increase the bonding force, polygonal prisms, petals, cylinders, grooves, etc. can also be used on the surface of the connecting pad 9.

[0086] Please see Figure 8 As shown, please refer to the following: Figure 1 and Figure 2 This application also provides a display device 200, which has a structure that is basically the same as the aforementioned display device 100. The main difference is that the display device 200 includes a display screen structure 10a and a circuit board 20a. The display screen structure 10a can be unfolded in both directions, that is, the display screen structure 10a can be unfolded to the left and to the right.

[0087] The display screen structure 10a includes two support components 1, two sets of first telescopic components 2, and two sets of second telescopic components 6. The two support components 1 are arranged side-by-side and can extend or retract in opposite directions. Each set of first telescopic components 2 includes multiple first telescopic components 2, and each set of second telescopic components 6 includes multiple second telescopic components 6. The structures of the support components 1, first telescopic components 2, and second telescopic components 6 are basically the same as in the previous embodiments; please refer to the foregoing, and further details will not be elaborated here.

[0088] The display structure 10a includes a flexible display component 3a, which is located on the surfaces of two support components 1. The opposite ends of the flexible display component 3a bypass the support components 1 and the first telescopic component 2 on the same side, allowing the flexible display component 3a to unfold towards the opposite sides. Specifically, the flexible display component 3a includes a flexible display screen 4a and two flexible circuit boards 5 connected to the opposite ends of the flexible display screen 4a. The flexible display screen 4a covers the first surface 101 of the two support components 1, enhancing the overall integrity of the screen display.

[0089] The circuit board 20a has a set of grooves 7 for each group of first telescopic components 2 and a set of support walls 8 for each group of second telescopic components 6.

[0090] In addition, the display structure 10a has a cavity 201 between the two support components 1. This cavity 201 can be filled with a rigid support to support the flexible display component 3a, or it can be filled with a material with a certain degree of flexibility. In this way, the display device 200 can be bent at the cavity 201, and finally realize a foldable screen.

[0091] The display device 100 (200) provided in this application embodiment can be applied to rollable and retractable screen electronic devices, and has the following beneficial effects:

[0092] 1. Flexibility: The display device 100 (200) has a flexible expansion function, and the screen size can be adjusted as needed, making it suitable for various scenarios such as home entertainment, office and study.

[0093] 2. Portability: Since the screen of display device 100 (200) can be extended and retracted, it is very easy to carry. Users can use the same device in different situations without worrying about the screen size being unsuitable.

[0094] 3. Innovation: The emergence of the display device 100 (200) has opened up entirely new possibilities for electronic device design. This innovative design concept makes these devices highly attractive in the market.

[0095] 4. Visual experience: The screen of the display device 100 (200) can be rolled up or unfolded, which makes the screen have a larger visual area when unfolded, thus improving the user's visual experience.

[0096] 5. Versatility: Since the display device 100 (200) can be freely extended and bent, it can be easily converted into different usage modes. For example, the screen can be unfolded to watch videos, or it can be folded up for easy carrying.

[0097] 6. Energy saving and environmental protection: When using the display device 100 (200), the lighting and shutdown of different display areas can be controlled independently, and areas that are not needed can be turned off. Compared with traditional tablets and mobile phones, this results in better battery life. This allows these devices to run for a long time, reducing the demand for batteries and contributing to environmental protection.
