[0030] The embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings and examples. The detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of this disclosure by way of example, but should not be used to limit the scope of this disclosure.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0033] Furthermore, the terms "first," "second," and similar words used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different parts.

Words such as "including" or "contains" mean that the element preceding the word encompasses the element listed after the word, and do not exclude the possibility of encompassing other elements as well.

[0034] Example 1

[0035] like Figure 1-5 As shown, a first aspect of this disclosure provides a display device, which includes: a panel 1 and a filler 2; a target area A is disposed on the panel 1; the filler 2 is disposed on the panel 1 to support the target area A, and there is a gap between the filler 2 located in the target area A and the panel 1 to form a target space D.

[0036] Specifically, panel 1 can be a composite panel of flexible glass and organic light-emitting diodes, or a composite panel of transparent polyimide film and liquid crystal display panel, etc. Panel 1 may also include drive board support components, etc., without specific limitations. Target area A can be the part of the foldable screen device that bends during the bending process. Taking a foldable screen mobile phone as an example, the foldable screen mobile phone can be divided into a first part and a second part. The display panel 1 of the foldable screen mobile phone is disposed on the first part and the second part. When the first part and the second part are flattened, the various parts of panel 1 used for display are coplanar. When the first part and the second part are bent, panel 1 bends, and the bent area can be target area A. The display device provided in this disclosure is not limited to foldable screen mobile phones, but can also be installed on electronic devices such as foldable screen tablets and foldable screen laptops, without specific limitations.

[0037] The filler 2 can be a fluid material that flows onto the panel 1 and, after curing, provides support for the panel 1. The filler 2 can be made of plastic; in this embodiment, it can be made of adhesive. Adhesive is dripped onto the panel 1 and can bond with other parts of the panel 1 to fix the position of the filler 2 relative to the panel 1. After curing, the filler 2 provides support for the target area A of the panel 1. The gap between the filler 2 and the panel 1 in the target area A can be understood as the filler 2 not directly contacting the corresponding part of the panel in the target area A. The target area A and the filler 2 are spaced apart. The specific implementation can be achieved by isolating the filler 2 from the target area A using a separator, or by controlling the amount of filler 2 used to prevent direct contact between the filler 2 and the target area A of the panel 1; no specific limitation is made. The target space D can be formed by the filler 2 and the portion of the panel 1 corresponding to the target area A, or it can be formed by the filler 2, other components of the panel 1, and the portion of the panel 1 corresponding to the target area A; no specific limitation is made.

[0038] The first aspect of this disclosure provides a display device, comprising: a panel 1 and a filler 2; the filler 2 is disposed on the panel 1, which supports a target area A, and a gap exists between the filler 2 and the panel 1 in the target area A, forming a target space D. The presence of the target space D prevents the filler 2 from contacting the portion of the panel 1 corresponding to the target area A. When the filler 2 solidifies, due to the existence of the target space D, the filler 2 cannot pull the portion of the panel 1 corresponding to the target area A when its volume changes, thus preventing creases from forming on the panel 1 due to the pull of the filler 2. Furthermore, since the filler 2 loses its adhesiveness after solidification, when the panel 1 is bent or pressed, the panel 1 only undergoes a small deformation before contacting the filler 2, allowing the filler 2 to effectively support the panel 1 and effectively reduce creases.

[0039] like Figure 1 , 2 As shown, in some embodiments, panel 1 includes: display component 11 and support component 12; display component 11 has a display surface and a connecting surface facing away from each other; support component 12 is connected to the connecting surface so that the display surface can be bent based on target area A, filler 2 is connected to support component 12, and filler 2, connecting surface and support component 12 form target space D.

[0040] like Figure 4 , 5 As shown, specifically, the display component 11 can be a flexible screen, such as an LED flexible screen or an OLED flexible screen, etc., without specific limitation. The display component 11 has opposing display surfaces and connecting surfaces along its thickness direction. The surface of the display component 11 used to display content can be the display surface, and the connecting surface opposite to the display surface is used to connect the display component 11 driving component or other parts of the electronic device, without specific limitation. For example... Figure 4 As shown, the support component 12 can be two support blocks, spaced apart on the connection surface of the display component. The area enclosed by the two support blocks and the connection surface of the display component 11 can be the target area A of the panel 1. Because there is a gap between the two support blocks in the target area A, the display surface can be bent based on the target area A. The connection method between the display component 11 and the support component 12 can be by adhesive bonding or by a slot connection, without specific limitations. Figure 5 As shown, the support component 12 can also be a support block with multiple slots, and the positions of the multiple slots can be deformed. The support component 12 is set on the display component 11, and the corresponding positions of the multiple slots can be the target area A. The specific structure of the support component 12 is not limited. This setting allows the display component 11 to be bent while maintaining a simple structure and convenient installation.

[0041] like Figure 1 , 2 As shown, in some embodiments, the display device further includes a functional component 3, which is disposed in the target area A, connected to the panel 1, and located between the filler 2 and the panel 1.

[0042] Specifically, the functional component 3 is not specifically limited and can be ceramic or a coating, etc. The functional component 3 is a component that does not adhere to the filler 2 or can deform as the filler 2 cures, and is not specifically limited in this regard. The connection between the functional component 3 and the panel 1 can be by bonding or by connecting through components such as slots. It can be understood that the functional component 3 is set in the target space D. During the assembly of the display device, a fluid-like filler 2 is placed on the panel 1. The filler 2 is bonded to the panel 1 and is in contact with the functional component 3. During the curing process of the filler 2, the volume of the filler 2 decreases. Since the filler 2 is not bonded to the display component 11, and the functional component 3 isolates the filler 2 from the panel 1 within the target area A, the filler 2 will not pull the panel 1 during the curing process or as a component that can deform with the curing of the filler 2. This effectively avoids creases on the panel 1 caused by the panel 2 being pulled due to the curing of the filler 2. Furthermore, the setting of the functional component 3 can effectively reduce the difficulty of setting the filler 2, thereby improving the production efficiency of the display device.

[0043] like Figure 1-3 As shown, in some embodiments, the panel 1 has at least one first through groove 4, which corresponds to the target area A, and the filler 2 seals the first through groove 4 at the opening of the first through groove 4.

[0044] Specifically, the first through-slot 4 on panel 1 can be designed according to the structure of panel 1 and is not specifically limited thereto. The first through-slot 4 can be a groove structure formed by the connecting surfaces of the support component 12 and the display component 11, so that the first through-slot 4 corresponds to the target area A. The support component 12 can also be a support block set on the display component 11, and multiple first through-slots 4 can be formed on the support block, without limiting the specific structure of the first through-slot 4. The first through-slot 4 makes the bending of the display device easier and smoother, and has a simple structure and simple process. During the assembly of the display device, the fluid filler 2 can flow into the groove through the opening of the first through-slot 4 and adhere to the first through-slot 4. After the fluid filler 2 solidifies, it can support the target area A.

[0045] like Figure 1-3 As shown, in some embodiments, the first through groove 4 and the filler 2 form a sealed target space D, and the bottom of the first through groove 4 is provided with a second through groove 5 surrounding the target space D, and the target space D communicates with the internal space of the second through groove 5.

[0046] Specifically, the filler 2 is disposed at the opening of the first through groove 4, and completely seals the interior of the first through groove 4 to form a sealed target space D. The second through groove 5 can be a groove formed on the support component 12, without specific limitations. The second through groove 5, which surrounds the target space D, can be formed by a chamfered structure or a rounded transition structure on the side of the support component 12 near the display component 11, so that the chamfered structure or rounded transition structure on the support component 12 and the connecting surface of the display component 11 form the second through groove 5. In this embodiment, the chamfered structure can be formed on the support component 12 near the display component 11. Specifically, the chamfered structure can be made on the support component 12 using an asymmetric etching process to facilitate precise control of the chamfered structure's dimensions. In this embodiment, the included angle R between the chamfered structure bevel and the connecting surface of the display component 11 can be controlled to be less than 30°, specifically 25° or 20°. The specific angle can be set according to the actual amount of filler used. In this embodiment, controlling the included angle R to be less than 30° can prevent the interior of the second through groove 5 from being wetted by the fluid filler.

[0047] During the assembly of the display device, the fluid filler 2 flows into the first channel section 4, compressing the gas originally present in the first channel section 4 into the second channel section 5. After the fluid filler 2 solidifies, its volume shrinks and forms the target area A with the panel 1. At this time, the gas compressed into the second channel section 5 flows into the target space D to form a gas support structure in the target space D. The gas support structure, together with the filler 2, supports the panel 1, further reducing the creases on the panel 1.

[0048] In some embodiments, the functional element 3 and the filler 2 are spaced apart. Alternatively, the functional element 3 is connected to the filler 2, and the functional element 3 can deform along with the filler 2.

[0049] like Figure 1 , 3 As shown, specifically, when the functional component 3 and the filler 2 are spaced apart, the functional component 3 can be a material that does not adhere to the filler 2, that is, a material that is not easily bonded by adhesive, such as carbon fiber composite material, wax material, etc., without specific limitations. In this embodiment, an anti-fingerprint coating can be provided on the target area A, that is, an anti-fingerprint coating can be provided at the bottom of the groove of the first through groove 4. The anti-fingerprint coating can isolate the display component 11 from the filler 2, prevent the filler 2 from adhering to the display component 11, and effectively prevent the filler 2 from pulling the display component 11 due to volume reduction during curing.

[0050] like Figure 2As shown, when the functional component 3 is connected to the filler 2, and the functional component 3 can deform along with the filler 2, the functional component 3 can be a soft rubber pad or an air bladder, without specific limitations. The functional component 3 can be connected to the display assembly 11 via adhesive or via a slot, without specific limitations. The functional component 3 can be bonded to the filler 2. During the curing process of the filler 2, the filler 2 can pull the functional component 3 to deform, thereby preventing the filler 2 from pulling on the display assembly 11. At the same time, the functional component 3 is disposed in the target space D and fills the interior of the target space D to provide certain support for the display assembly 11, effectively reducing creases in the display device.

[0051] like Figure 1-3 As shown, in some embodiments, a drainage structure 6 is provided at the opening of the first through groove 4.

[0052] Specifically, the flow guiding structure 6 can be a chamfered structure or an arc transition structure at the slot opening. It can be obtained by asymmetric etching or by hand engraving. Its specific dimensions can be designed according to the amount of filler used and are not specifically limited. During the assembly of the display device, the flow guiding structure 6 can guide the filler 2 to flow along a specific path, allowing the filler 2 to drip more accurately into the first through slot 4, effectively preventing the filler 2 in a fluid state from overflowing out of the slot opening, thus ensuring the quality of the display device.

[0053] Example 2

[0054] A second aspect of this disclosure provides an electronic device, including a first body, a second body, and a display device connected to the first body and the second body. The display device includes a panel 1 and a filler 2. The panel 1 has a target area A located at the junction of the first body and the second body. The filler 2 is disposed on the panel 1 to support the target area A. A gap exists between the filler 2 and the panel 1 in the target area A to form a target space D. The panel 1 remains flat when the first body and the second body rotate relative to each other to switch between a folded state and an unfolded state.

[0055] Specifically, the first and second bodies can be a collection of electronic components used to drive the display device, including a motherboard, battery, and storage components, etc., without specific limitations. The connection between panel 1 and the first and second bodies can be an electrical connection, so that the content processed by the first and second bodies can be displayed on the display device. Panel 1 also needs to be fixedly connected to the first and second bodies. The fixed connection can be through a slot connection or through adhesive bonding, without specific limitations. The target area A is set between the first and second bodies and is located at the connection between the first and second bodies. The first and second bodies can be connected by a hinge, so that when the electronic device is bent, panel 1 can be bent or flattened based on the target area A, and the first and second bodies can also be bent or flattened relative to each other, so that when the first and second bodies rotate relative to each other to switch between folded and unfolded states, panel 1 remains flat. With this configuration, due to the existence of the target space D, the volume change of the filler 2 cannot pull the part of panel 1 corresponding to the target area A, preventing creases from appearing on panel 1 due to the pull of the filler 2. It can effectively enhance the display effect of electronic devices, thereby increasing the user's comfort in using electronic devices.

[0056] like Figure 4 , 5 As shown, in some embodiments, panel 1 is provided with a first region B and a second region C. The first region B is connected to a first body, and the second region C is connected to a second body. The target region A is located between the first region B and the second region C. When in a folded state, the target region A is bent and smoothly transitions with the first region B and the second region C. When in an unfolded state, the target region A is coplanar with the first region B and the second region C.

[0057] Specifically, the first region B and the second region C of panel 1 can be two regions arranged along the length direction of panel 1 or two regions arranged along the width direction of panel 1, without specific limitation. The first region B can correspond to the cross-sectional shape in the thickness direction of the first body, and the second region C can correspond to the cross-sectional shape in the thickness direction of the second body. The first body and the second body can have the same shape. The target region A is located between the first region B and the second region C, and the target region A can correspond to the hinge position used to connect the first body and the second body. When in the folded state, the target region A is bent and smoothly transitions with the first region B and the second region C, which can be understood as the target region A, the first region B, and the second region C can have an arc-shaped transition. When in the unfolded state, the target region A, the first region B, and the second region C are coplanar, which can be understood as the target region A, the first region B, and the second region C can form a relatively flat plane.

[0058] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure.
