[0063] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. Like reference numerals in the figures represent identical or similar structures, and thus their detailed descriptions will be omitted. Furthermore, the figures are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale.

[0064] The terms "a", "an", "the", "said" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express open-ended inclusion and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.; the terms "first", "second", etc. are used only as labels and are not intended to limit the quantity of their objects.

[0065] An embodiment of the present disclosure provides a display device, as shown in FIG1 and FIG2 , which may include a display panel PNL and a driving part DP. The display panel PNL may include an inner panel PNL1, an outer panel PNL2, and a driving part DP, wherein:

[0066] The inner panel PNL1 has a first display area AA1 and a first peripheral area WA1 located outside the first display area AA1.

[0067] The outer panel PNL2 surrounds the inner panel PNL1 and has a gap between it and the inner panel PNL1. The outer panel PNL2 is a ring structure with a gap GA, which cuts through the outer panel PNL2. The outer panel PNL2 has a second display area AA2 and a second peripheral area WA2 located outside the second display area AA2. The outer panel PNL2 extends toward the non-luminous side of the inner panel PNL1.

[0068] The driving part DP is connected to the first peripheral area WA1 and the second peripheral area WA2 and is used to drive the first display area AA1 and the second display area AA2 to display images. The driving part DP is a bendable flexible structure.

[0069] The display device of the disclosed embodiment utilizes two panels, inner and outer, to achieve display. The outer panel PNL2 extends toward the non-luminous side of the inner panel PNL1, forming a slope extending toward the non-luminous side. The inner panel PNL1 can be used as the primary display area, while the outer panel PNL2, corresponding to the area at the edge of the display device, serves as the secondary display area. When used in a terminal device, this allows the originally non-luminous edge area to display images, thereby increasing the display area without increasing the overall size. Specifically, the first display area AA1 can be driven to emit light by the driver unit DP and the first peripheral area WA1, while the second display area AA2 can be driven to emit light by the driver unit DP and the second peripheral area WA2. Furthermore, the driver unit DP can be bent toward the non-luminous side of the inner panel PNL1, reducing the space occupied by the driver unit DP in the edge area, which helps to increase the screen-to-body ratio.

[0070] The following is a detailed description of the display device disclosed herein:

[0071] As shown in FIG. 2 , the display device may include a display panel PNL and a driving part DP connected to each other. The driving part DP may drive the display panel PNL to display an image.

[0072] The display panel PNL has multiple light-emitting devices, which can be OLEDs (organic light-emitting diodes) using organic light-emitting materials, or LEDs (light-emitting diodes) using inorganic light-emitting materials, such as Micro LEDs (micrometer light-emitting diodes) and Mini LEDs (sub-millimeter light-emitting diodes). The light-emitting devices can also be devices such as QLEDs (quantum dot diodes).

[0073] The display panel PNL may include a driving backplane and a light-emitting device located on one side of the driving backplane. The light-emitting side of the display panel PNL may be the side from which light is emitted, that is, the side of the light-emitting device away from the driving backplane. The non-light-emitting side of the display panel PNL may be the side opposite to the light-emitting direction, that is, the side of the driving backplane away from the light-emitting device.

[0074] The driver backplane contains a driving circuit that drives the light-emitting devices to emit light and display images. For example, the driver backplane may include a substrate and a circuit layer located on one side of the substrate. The substrate may be a flat plate and made of a hard material such as glass or a soft material such as polyimide. The substrate may be a single-layer or multi-layer structure. The circuit layer may be located on one side of the substrate.

[0075] The circuit layer may include a driving circuit, which can drive the light-emitting device to emit light. The driving circuit may include a pixel circuit and a peripheral circuit. The pixel circuit may be a 7T1C, 3T1C, or other pixel circuits, as long as it can drive the light-emitting device to emit light. No special limitation is made to its structure herein. Among them, nTmC means that a pixel circuit includes n transistors (represented by the letter "T") and m capacitors (represented by the letter "C"). The number of pixel circuits may be the same as the number of light-emitting devices, and they are connected to each light-emitting device in a one-to-one correspondence so as to control each light-emitting device to emit light separately. Of course, the number of pixel circuits may also be less than the number of light-emitting devices. For example, the same pixel circuit may be connected to multiple light-emitting devices and drive multiple light-emitting devices to emit light simultaneously. No special limitation is made herein. Alternatively, the number of pixel circuits may be more than the number of light-emitting devices. There may be dummy pixel circuits that are not connected to the light-emitting devices. These dummy pixel circuits may be distributed in areas without light-emitting devices, which is beneficial to improving the uniformity of the circuit layer.

[0076] The peripheral circuit is connected to the pixel circuit and is used to input a drive signal to the pixel circuit to control the light-emitting device to emit light. The peripheral circuit may include a gate drive circuit and a light-emitting control circuit, depending on the configuration of the pixel circuit. The peripheral circuit may also include thin-film transistors and capacitors. The specific structure of the peripheral circuit is not particularly limited here.

[0077] The above-mentioned circuit layer may include multiple thin film transistors and capacitors, wherein the thin film transistors may be top-gate or bottom-gate thin film transistors, and each thin film transistor may include an active layer and a gate. The active layer of each thin film transistor is arranged in the same semiconductor layer, and the gate may be arranged in the same gate layer to simplify the process.

[0078] The light-emitting device may include a first electrode, a second electrode, and a light-emitting layer located between the first and second electrodes. Applying an electrical signal to the first and second electrodes can excite the light-emitting layer to emit light. To prevent crosstalk and define the position of the light-emitting device, the display panel PNL may also include a pixel definition layer. This layer and the light-emitting device may be located on the same side of the driver backplane as the display panel PNL, for example, with the circuit layer away from the substrate surface.

[0079] The first electrodes of each light-emitting device are spaced apart, and the pixel definition layer is provided with pixel openings that expose each first electrode. That is, each pixel opening exposes one first electrode. The area corresponding to each pixel opening corresponds to the area of ​​each light-emitting device. The light-emitting layer is at least partially located within the pixel opening and is stacked with the first electrode. The light-emitting layer of each light-emitting device can be a continuous, single layer structure, or the light-emitting layers of different light-emitting devices can be spaced apart from each other.

[0080] The second electrode can cover the light-emitting layer and can be a continuous, full-layer structure, allowing each light-emitting device to share the same second electrode. The second electrode can be the cathode of the light-emitting device and can adopt a light-transmitting structure, allowing the light-emitting device to emit light in a direction away from the driving backplane.

[0081] In addition, the display panel PNL may further include an encapsulation layer, which may cover each light-emitting device and be used to block external water and oxygen from corroding the light-emitting device. For example, the encapsulation layer may be a thin film encapsulation method, which may include a first inorganic layer, an organic layer, and a second inorganic layer, wherein:

[0082] The first inorganic layer can cover each light-emitting device. The organic layer can be provided on the surface of the first inorganic layer away from the driver backplane, and the boundary of the organic layer can be confined to the inside of the boundary of the first inorganic layer by a barrier dam or other structure surrounding the light-emitting device. The second inorganic layer can cover the organic layer and the first inorganic layer not covered by the organic layer, and the second inorganic layer can block the intrusion of water and oxygen, and achieve flattening by the organic layer having fluidity before curing. The materials of the first and second inorganic layers can include inorganic insulating materials such as silicon nitride and silicon oxide.

[0083] In some embodiments of the present disclosure, the display device may further include a functional layer FL, which may be disposed on a side of the encapsulation layer away from the driver backplane. The functional layer FL may include a touch layer for sensing touch operations. The touch layer may employ a self-capacitive, mutual-capacitive, or resistive touch structure, without particular limitation. Of course, the functional layer FL may also not include a touch layer.

[0084] As shown in Figures 3 and 4 , the functional layer FL may also include a color filter layer having multiple filter sections. For a monolithic light-emitting layer, the filter sections can filter light to achieve color display. For spaced light-emitting layers, the color filter layer can filter ambient light and reduce reflection. Of course, for spaced light-emitting layers, the color filter layer can be omitted and replaced with a circular polarizer.

[0085] As shown in Figures 3 and 4, in some embodiments of the present disclosure, the display device of the present disclosure may further include a transparent cover CG, which may be glass or other transparent materials, and may be arranged on the side of the functional layer FL away from the display panel PNL. For example, the transparent cover CG may be bonded to the surface of the functional layer FL away from the display panel PNL through an adhesive layer OC.

[0086] As shown in Figures 3 and 4, in some embodiments of the present disclosure, the display panel PNL may further include a buffer heat dissipation layer SL, which may be provided on the backlight surface of the display panel PNL, that is, the surface of the driving backplane away from the light-emitting device. The buffer heat dissipation layer SL may include a back film and a support layer, and the back film may be attached to the surface of the driving backplane away from the light-emitting device. The support layer may be attached to the surface of the back film away from the light-emitting device. The support layer may include an adhesive layer, a buffer layer and a heat dissipation layer stacked in a direction away from the display panel PNL, wherein the adhesive layer may be made of mesh adhesive, etc., the buffer layer may be made of foam and other materials, and the heat dissipation layer may be made of copper or other metal materials with good thermal conductivity. At the same time, the heat dissipation layer made of metal material may also play a role in improving strength. In addition, the display panel PNL may also not be provided with a back film, and the heat dissipation layer may be directly provided on the surface of the driving backplane away from the light-emitting device.

[0087] As shown in FIG2 , the display panel PNL of the present disclosure can be divided into at least an inner panel PNL1 and an outer panel PNL2 which are independent of each other. Both the inner panel PNL1 and the outer panel PNL2 have the above-mentioned light emitting devices and driving circuits.

[0088] The light emitting sides of the inner panel PNL1 and the outer panel PNL2 are the light emitting sides of the display panel PNL, and the non-light emitting sides of the inner panel PNL1 and the outer panel PNL2 are the non-light emitting sides of the display panel PNL.

[0089] The inner panel PNL1 may include a first display area AA1 and a first peripheral area WA1 located outside the first display area AA1. The first peripheral area WA1 may be a closed or open annular area surrounding the first display area AA1. The first display area AA1 includes a light-emitting device and a pixel circuit connected thereto, namely, a first light-emitting device and a first pixel circuit. The first peripheral area WA1 also includes a peripheral circuit, namely, a first peripheral circuit. The first peripheral circuit can output control signals to the first pixel circuit to control the light-emission timing and grayscale of the first light-emitting device, thereby enabling the inner panel PNL1 to display an image.

[0090] As shown in Figure 2, the outer panel PNL2 can surround the inner panel PNL1 with a gap between them, meaning that the inner panel PNL1 and the outer panel PNL2 do not directly contact each other. The outer panel PNL2 can be annular and include a gap GA that radially divides the outer panel PNL2 from the inner panel PNL1, rendering the outer panel PNL2 circumferentially open. The gap between the inner and outer panels PNL1 can be formed by dividing the inner and outer panels PNL2 using the same display panel PNL. Alternatively, the inner and outer panels PNL1 and PNL2 can be manufactured separately.

[0091] As shown in Figures 1-4, the outer panel PNL2 can be a flexible panel and can extend toward the non-luminous side of the inner panel PNL1, forming a slope extending toward the non-luminous side of the inner panel PNL1. The angle α between the outer panel PNL2 and the inner panel PNL1 can be an obtuse angle. In this state, the display panel PNL is in a deformed state. In the expanded state, the outer panel PNL2 and the inner panel PNL1 can lie along the same plane. By deforming the outer panel PNL2, the aforementioned slope can be formed, and during the slope formation process, the gap GA can gradually decrease. In other words, the expanded state is when the outer panel PNL2 has no slope, while the deformed state is when the outer panel bends into a slope. During the transition from the expanded state to the deformed state, the circumferential dimension of the outer panel PNL2 decreases due to the presence of the gap GA. Specifically, the gap GA provides space for the contraction of the outer panel PNL2 during deformation. If the outer panel PNL2 were a completely closed annular structure, wrinkling would inevitably occur during bending. The gap GA can prevent this wrinkling. The display panel PNL of the present disclosure may be in a deformed state when applied to a terminal device, and the expanded state may exist during the manufacturing and assembly processes before leaving the factory.

[0092] The outer panel PNL2 includes a second display area AA2 and a second peripheral area WA2 located outside the second display area AA2. The second peripheral area WA2 and the second display area AA2 may be annular areas concentrically surrounding the outer surface of the inner panel PNL1. Consistent with the shape of the outer panel PNL2, the second display area AA2 and the second peripheral area WA2 are discontinuous at the gap GA. The second display area AA2 includes a light-emitting device and a pixel circuit connected thereto, namely, a first light-emitting device and a first pixel circuit. The second peripheral area WA2 includes a peripheral circuit, namely, a second peripheral circuit. The second peripheral circuit can output control signals to the second pixel circuit to control the light-emission timing and grayscale of the second light-emitting device, thereby enabling the outer panel PNL2 to display an image.

[0093] As shown in Figures 1 and 2, in some embodiments of the present disclosure, the outline of the inner panel PNL1 is circular, the outline of the outer panel PNL2 is an open circular ring, and the shape of the display panel PNL composed of the sloped outer panel PNL2 and the inner panel PNL1 can be a truncated cone.

[0094] As shown in Figures 16 and 17, in some embodiments of the present disclosure, the inner panel PNL1 can have a rectangular or other polygonal outline, while the outer panel PNL2 can have an open polygonal ring structure. The display panel PNL formed by the sloped outer panel PNL2 and inner panel PNL1 can have a prism-shaped shape. Figure 16 shows a top view of the expanded state, while Figure 17 shows a top view of the deformed state. Of course, the aforementioned polygons, including corners, can be rounded.

[0095] As shown in Figures 2, 5, and 19, the driver unit DP can be provided with a driver chip DC, and the peripheral circuits of the display panel PNL can be connected to the driver chip DC, so that the driver chip DC can control the peripheral circuits to output drive signals, causing the display panel PNL to display images. The aforementioned internal display unit and external display unit can be controlled by the same driver unit DP and the driver chip DC thereon. In this case, the inner panel PNL1 and the outer panel PNL2 need to be connected together and then connected to the driver unit DP. Alternatively, the driver unit DP can be divided into two independent sub-driver units DP, each of which can be provided with a driver chip DC. The two driver units DP can drive the inner panel PNL1 and the outer panel PNL2 respectively. In this case, the sub-driver units DP can drive the inner panel PNL1 and the outer panel PNL2 respectively, and the inner panel PNL1 and the outer panel PNL2 can be completely disconnected.

[0096] As shown in Figures 4 and 20 , the driver DP can be a flexible structure. In a deformed state, it can bend toward the non-luminous side of the display panel PNL. In an extended state, the driver DP can extend along the extension direction of the display panel PNL. For example, the driver DP and the display panel PNL can be an integrated flexible structure, allowing the driver DP and the display panel PNL to be formed simultaneously, which helps simplify the structure. Of course, the driver DP can also be a flexible circuit board provided independently of the display panel PNL, as long as it can be connected to the display panel PNL.

[0097] First type of implementation

[0098] As shown in Figures 2-4 , the display panel PNL may include a connection portion CP that connects the inner panel PNL1 and the outer panel PNL2. The connection portion CP includes a trace that connects the first peripheral area WA1 to the second peripheral area WA2. Furthermore, the connection portion CP is a flexible, bendable structure. When the display panel PNL is deformed from an expanded state to a deformed state, the connection portion CP bends accordingly, ensuring a connection without hindering the change in state.

[0099] In some embodiments, the driver portion DP may be connected to the second peripheral area WA2 of the outer panel PNL2. In the expanded state, the driver portion DP is connected to a side of the outer panel PNL2 away from the inner panel PNL1 and extends away from the inner panel PNL1. The driver portion DP may be connected to the first peripheral area WA1 via the second peripheral area WA2 and the connection portion CP. Specifically, the first peripheral circuit within the first peripheral area WA1 of the inner panel PNL1 and the second peripheral area WA2 may be connected to the driver portion DP via the connection portion CP. Specifically, the first peripheral area WA1 and the second peripheral area WA2 may be provided with traces connecting the first peripheral circuit. These traces may be connected via traces within the connection portion CP and connected to the driver chip DC via traces within the driver portion DP, thereby forming a path connecting the first peripheral circuit and the driver chip DC. Simultaneously, the second peripheral circuit in the second peripheral area WA2 of the outer panel PNL2 may be directly connected to the driver chip DC via traces within the driver portion DP.

[0100] The connection portion CP can be an integral flexible structure with the inner panel PNL1 and the outer panel PNL2, allowing the connection portion CP to be formed simultaneously with the display panel PNL, thereby simplifying the structure and eliminating the need for a dedicated connection process. Alternatively, the connection portion CP can be a flexible circuit board provided independently of the display panel PNL, as long as it can be used to connect the first peripheral circuit and the driver portion DP.

[0101] In some embodiments, as shown in FIG2 , the connection portion CP and the gap GA may be distributed along a radial straight line, namely, along a straight line S passing through the center of the inner panel PNL1. Simultaneously, the outer panel PNL2 may be symmetrical about this straight line S, i.e., the outer panel PNL2 may have an axisymmetric profile. Because the connection portion CP connects the inner panel PNL1 and the outer panel PNL2, the connection portion CP can be symmetrical about this straight line S, resulting in balanced forces on the outer panel PNL2 on both sides of the connection portion CP.

[0102] Furthermore, as shown in Figure 2, in one embodiment, the driving portion DP, the connecting portion CP and the gap GA can be distributed along a radial straight line S, that is, along a straight line S passing through the center of the inner panel PNL1, so that the driving portion DP and the connecting portion CP are connected on both sides of the same area of ​​the outer panel PNL2, so that the force points of the outer panel PNL2 are concentrated, and other areas are not easily affected during deformation.

[0103] Of course, in other embodiments of the present disclosure, the driving portion DP and the connecting portion CP may also be distributed along the circumference of the outer panel PNL2. As shown in Figure 5, the connecting portion CP and the notch GA may be distributed along a straight line S1, and the driving portion DP and the center of the inner panel PNL1 may be distributed along a straight line S2. The angle α between the straight line S1 and the straight line S2 is greater than 0° and less than 180°. Except for the notch GA, the driving portion DP may be provided at any position on the outer side of the outer panel PNL2. The specific position of the driving portion DP is not specifically limited here.

[0104] Furthermore, in some embodiments, since the driver portion DP is located outside the outer panel PNL2, the inner panel PNL1 does not need to be equipped with a dedicated driver portion DP, nor does it need to utilize a gap GA to avoid the driver portion DP. This allows the gap GA to be minimized. For example, as shown in FIG2 , in the expanded state, the angle θ between the ends of the gap GA and the center of the inner panel PNL1 can be no greater than 30°, for example, 30°, 20°, etc. This angle can be the angle between the centers of the two ends of the gap GA and the center of the inner panel PNL1. Furthermore, the width L of the gap GA can be no greater than 8 mm, for example, 8 mm, 6 mm, etc., to minimize the loss of the outer panel PNL2 at the gap GA. The width of the gap GA is the distance between the two segments. In the deformed state, the ends of the gap GA can either touch or have a gap.

[0105] As shown in FIG2 , taking the distribution of the driving portion DP, connecting portion CP, and gap GA along a straight line S passing through the center of the inner panel PNL1 as an example, the connecting portion CP and the driving portion DP can be bent toward the non-luminous side of the inner panel PNL1. By bending the connecting portion CP, the outer panel PNL2 can be extended toward the non-luminous side of the inner panel PNL1, forming an obtuse angle with the inner panel PNL1. By completing the driving portion DP, the driving portion DP can be extended to a corresponding position on the inner panel PNL1.

[0106] As shown in Figure 3, in the deformed state, the driving part DP may include a first bent portion BP1, a first extension portion FP1, a second bent portion BP2 and a second extension portion FP2; the first bent portion BP1 connects the outer panel PNL2 and the first extension portion FP1, and the second bent portion BP2 connects the first extension portion FP1 and the second extension portion FP2.

[0107] The first bent portion BP1 can bend toward the non-light-emitting side of the outer panel PNL2, and the first extension portion FP1 can extend along the extension direction of the outer panel PNL2, such that the first extension portion FP1 is parallel to the outer panel PNL2. The second bent portion BP2 can bend in the same direction as the connection portion CP, that is, the two can bend about parallel straight lines. At the same time, the second extension portion FP2 can extend along the extension direction of the inner panel PNL1, such that the second extension portion FP2 is arranged parallel to the inner panel PNL1.

[0108] Furthermore, as shown in Figure 3, a gasket SG can be set between the second extension portion FP2 and the inner panel PNL1 and between the first extension portion FP1 and the outer panel PNL2. For example, a first gasket can be set between the second extension portion FP2 and the inner panel PNL1, and the first gasket plays a role in supporting the second extension portion FP2; the first gasket can be clamped between the buffer heat dissipation layer SL at the second extension portion FP2 and the buffer heat dissipation layer SL at the inner panel PNL1, and can be bonded to the second extension portion FP2 through the adhesive layer GL.

[0109] A second gasket may be provided between the first extension portion FP1 and the outer panel PNL2, and the second gasket serves to support the first extension portion FP1; the second gasket may be clamped between the buffer heat dissipation layer SL at the first extension portion FP1 and the buffer heat dissipation layer SL at the outer panel PNL2, and may be bonded to the first extension portion FP1 through another adhesive layer GL.

[0110] Of course, in other embodiments of the present disclosure, the gasket SG may be provided only between the second extension portion FP2 and the inner panel PNL1 , or only between the first extension portion FP1 and the outer panel PNL2 .

[0111] The gasket SG can be made of metal or alloy, or of non-metallic material, as long as it can play a supporting role.

[0112] In addition, as shown in Figures 3 and 4, for the solution in which the driving part DP, the connecting part CP and the display panel PNL can be an integrated structure, in order to facilitate bending, the buffer heat dissipation layer SL can be disconnected in the areas corresponding to the first bending part BA1 and the second bending part BA2. Furthermore, the functional layer FL can also be disconnected in at least one corresponding area of ​​the first bending part BA1 and the second bending part BA2.

[0113] As shown in Figures 3 and 4 , in some embodiments of the present disclosure, when the display panel PNL is in a deformed state, the transparent cover plate CG can be attached to the display panel PNL accordingly. For example, the transparent cover plate CG is bonded to the surface of the functional layer FL away from the driving backplane via an adhesive layer OC. The transparent cover plate CG may include a central portion CG1, a transition portion CG2 surrounding the central portion CG1, and an edge portion CG3 surrounding the transition portion CG2. Specifically:

[0114] The center portion CG1 can cover the inner panel PNL1, and the boundaries of the center portion CG1 and the inner panel PNL1 can be aligned in a direction perpendicular to the inner panel PNL1. The transition portion CG2 can cover the area between the inner panel PNL1 and the outer panel PNL2 and bend toward the non-luminous side of the display panel PNL. In the area corresponding to the connection portion CP, it can conform to the connection portion CP and bend synchronously. The area between the inner panel PNL1 and the outer panel PNL2 without the connection portion CP does not contact the display panel PNL. The edge portion CG3 can cover the outer panel PNL2 and conform to the outer panel PNL2. Of course, it can also not conform to the outer panel PNL2, but the edge of the outer panel PNL2 is located within the edge of the edge portion CG3, and the outer panel PNL2 does not protrude from the transparent cover plate CG.

[0115] As shown in Figures 3, 4, and 15, to shield the non-luminous areas, such as the peripheral areas of the inner and outer panels PNL1 and PNL2, as well as the area between the inner and outer panels PNL1 and PNL2, the display device further includes a light absorbing layer BM, at least partially disposed between the transparent cover plate CG and the display panel PNL. The light absorbing layer BM can be made of black resin or other light absorbing materials, and can include a first light absorbing portion BM1 and a second light absorbing portion BM2 surrounding the first light absorbing portion BM1. The following are the details:

[0116] The first light absorbing portion BM1 can cover the area between the inner panel PNL1 and the outer panel PNL2. It can be a ring-shaped structure, and the distance between the inner and outer boundaries of the first light absorbing portion BM1 can be greater than the distance between the inner panel PNL1 and the outer panel PNL2, and also greater than the length of the connecting portion CP in the radial direction of the inner panel PNL1; ensuring that the first light absorbing portion BM1 can block the area between the inner panel PNL1 and the outer panel PNL2.

[0117] The orthographic projection of the second light absorbing portion BM2 on the transparent cover plate CG may extend along the edge of the transparent cover plate CG toward the first light absorbing portion BM1 , but may not contact the first light absorbing portion BM1 . The second light absorbing portion BM2 may also be an annular structure.

[0118] At least one of the first light absorbing portion BM1 and the second light absorbing portion BM2 can be a continuous annular structure that spans the area corresponding to the gap GA. Alternatively, one or both of the first and second light absorbing portions BM1 and BM2 can be discontinuous annular structures, interrupted at the location corresponding to the gap GA. Furthermore, to shield the gap GA, the light absorbing layer BM can further include a third light absorbing portion BM3, which can shield the gap GA and is integral with the first and second light absorbing portions BM1 and BM2.

[0119] By matching the range of the first light absorbing portion BM1 and the second light absorbing portion BM2 with the range of the first display area AA1 and the second display area AA2, the first display area AA1 is located within the range surrounded by the first light absorbing portion BM1, and the boundary of the first display area AA1 can be aligned with the inner boundary of the first light absorbing portion BM1 in a direction perpendicular to the inner panel PNL1; the second display area AA2 can be located between the first light absorbing portion BM1 and the second light absorbing portion BM2, and the inner boundary of the second display area AA2 can be aligned with the outer boundary of the first light absorbing portion BM1 in a direction perpendicular to the outer panel PNL2, and the outer boundary of the second display area AA2 can be aligned with the inner boundaries of the two light absorbing portions in a direction perpendicular to the outer panel PNL2.

[0120] As shown in Figures 3, 4, and 15, based on the aforementioned light absorbing layer BM, two black annular structures can be visually seen on the display device. The outer portion corresponds to the area of ​​the second light absorbing portion BM2, and the inner portion corresponds to the area of ​​the first light absorbing portion BM1. Figure 15 is a top view of the light absorbing layer BM of the display device in Figure 2 in a deformed state, i.e., a top view of the light absorbing layer BM of the display device in Figures 3 and 4. Meanwhile, referring to Figure 18, which is a top view of the light absorbing layer BM of the display device in Figure 17, it can be seen that two black annular structures can be visually seen on the display device. The outer portion corresponds to the area of ​​the second light absorbing portion BM2, and the inner portion corresponds to the area of ​​the first light absorbing portion BM1. These annular structures are not circular rings, but rather square rings with rounded corners.

[0121] In some embodiments, the light absorbing layer BM may be disposed on the surface of the transparent cover plate CG close to the display panel PNL, and the first light absorbing portion BM1 may be conformally bonded to the transition portion of the transparent cover plate CG.

[0122] As shown in FIG8 , in some embodiments, the light absorbing layer BM may further include a fourth light absorbing portion BM4 , which may be provided on the outer peripheral surface of the transparent cover plate CG to absorb light leakage from the edge. The fourth light absorbing portion BM4 and the second light absorbing portion BM2 may be an integrated structure.

[0123] As shown in Figure 9, to reduce resistance from the deployed state to the deformed state, an opening HO can be provided in at least one of the connecting portion CP and the driving portion DP. This opening HO improves flexibility and facilitates bending. The opening HO can be a through hole that penetrates the connecting portion CP and the driving portion DP, or a blind hole that does not penetrate, as long as it improves flexibility and facilitates deformation.

[0124] The shape of the opening HO is not particularly limited herein. For example, the opening HO may be circular (as shown in FIG. 12 ), elliptical, arc-shaped, polygonal, or rounded (as shown in FIG. 10 ). The polygonal shape may be rectangular (as shown in FIG. 11 ), rhombus-shaped, or the like. Of course, other shapes may also be used. Using a shape with a curved area, such as a circular, elliptical, or rounded shape, can reduce or avoid sharp edges and corners, thereby preventing stress concentration and reducing the risk of rupture of the connecting portion CP and the driving portion DP.

[0125] As shown in Figures 10 to 12, in some embodiments of the present disclosure. The connecting part CP and the driving part DP are both provided with a plurality of openings HO. Taking one of the connecting part CP and the driving part DP as an example: each opening HO can be divided into a plurality of hole groups distributed along the first direction X, and each hole group may include a plurality of openings HO distributed at intervals along the second direction Y. The first direction X and the second direction Y are directions that intersect with each other. For example, the first direction X and the second direction Y are perpendicular. Furthermore, the driving part DP, the connecting part CP and the gap GA can be distributed along a straight line extending in the second direction Y. Therefore, it is conducive to designing the routing path of the connecting part CP and the driving part DP. The routing can pass through the area between the two hole groups without having to make the routing have more bending parts in order to avoid the openings HO.

[0126] As shown in Figures 10 to 12, in two adjacent hole groups in the first direction X, any opening HO of one hole group corresponds to the area between two adjacent openings HO of the other hole group, that is, the openings HO of the two adjacent hole groups are staggered, so that the distance between two adjacent openings HO distributed along the same straight line in the first direction X (there are no other openings HO between the two openings HO) is enlarged, which is beneficial to improving the strength of the connecting part CP and the driving part DP while meeting the flexibility requirements, so that they are not easily broken due to bending.

[0127] As shown in Figures 9 and 10, in one embodiment, the opening HO is in the shape of an oval circle, and the above-mentioned staggered arrangement can be adopted, which can avoid stress concentration and reduce the risk of rupture. In other embodiments of the present disclosure, the connection part CP and the driving part DP are each provided with a plurality of openings HO, and on one of the connection part CP and the driving part DP. As shown in Figures 11 and 12, the openings HO can also be distributed in an array such as a rectangle or a circle. Alternatively, the openings HO can be distributed along a straight line extending in the first direction X (as shown in Figure 13) or the second direction Y. Alternatively, if the openings HO are arc-shaped, the plurality of openings HO can be distributed concentrically around the inner panel PNL1 in a direction away from the inner panel PNL1. In addition, as shown in Figures 9 and 14, the openings HO can be rectangular and can be distributed radially around the inner panel PNL1. Of course, other distribution methods can also be adopted, which are not listed here one by one.

[0128] The shapes and arrangements of the openings HO described above may be combined in various ways, and the shapes and arrangements of the openings HO of the connecting portion CP and the driving portion DP may be different.

[0129] Furthermore, in some embodiments, as shown in Figures 3 and 9, the driving part DP may include an opening area DPa and a non-opening area DPb, the openings HO of the driving part DP are all the opening areas DPa, the non-opening area DPb may not have openings HO, and the driving chip DC may be arranged in the non-opening area DPb.

[0130] In some embodiments of the present disclosure, as shown in Figures 10-14 , the maximum dimension W of the opening HO is no less than 0.005 mm and no greater than 2 mm, for example, 0.005 mm, 0.015 mm, 0.1 mm, 1 mm, 2 mm, etc. This maximum dimension can be the distance between the two points on the contour of the opening HO that are farthest apart. For example, as shown in Figure 10 , if the opening HO is a round shape, the maximum dimension W is the length of the round shape; as shown in Figures 11 and 13 , if the opening HO is a rectangle, the maximum dimension W is the length of the rectangle. As shown in Figure 12 , if the opening HO is a circle, the maximum dimension W is the diameter of the circle.

[0131] In some embodiments of the present disclosure, in the deformed state, the radius of curvature of the connection portion CP is not less than 0.5 mm and not greater than 5 mm, for example, 0.5 mm, 1.5 mm, 2.5 mm, 3.5 mm, and 5 mm. The radius of curvature of the opening area DPa is not less than 0.1 mm and not greater than 2 mm, for example, 0.1 mm, 0.5 mm, 1 mm, 1.5 mm, and 2 mm, and is not particularly limited herein.

[0132] The second embodiment of the present disclosure

[0133] As shown in Figures 19 and 20, the inner and outer panels PNL1 and PNL2 of the display panel PNL can be driven independently, and are not connected by the connection portion CP described above, but can be completely disconnected. The outer panel PNL2 has a flexible structure that can extend toward the non-luminous side of the inner panel PNL1, forming a truncated cone or prism-shaped structure with the inner panel PNL1. In this state, the display panel PNL is in a deformed state. In the expanded state, the outer panel PNL2 and the inner panel PNL1 extend along the same plane.

[0134] As shown in FIG19 , the driving part DP may include a first sub-driving part DP1 and a second sub-driving part DP2 that are independent of each other, wherein:

[0135] The first sub-driver DP1 can be connected to the first peripheral area WA1 of the inner panel PNL1. It can be a flexible structure. When the display panel PNL is in the unfolded state, the first sub-driver DP1 can extend along the extension direction of the inner panel PNL1. The first sub-driver DP1 and the display panel PNL can be an integrated flexible structure, or the first sub-driver DP1 can be a flexible circuit board provided independently of the inner panel PNL1. In the deformed state, the first sub-driver DP1 can bend toward the non-luminous side of the inner panel PNL1.

[0136] The first sub-driving part DP1 may include a first driving chip DC1, and the first peripheral circuit of the inner panel PNL1 may be connected to the first driving chip DC1, so that the first peripheral circuit may be controlled by the first driving chip DC1 to output a driving signal, so that the inner panel PNL1 displays an image.

[0137] The second sub-driver DP2 is connected to the second peripheral area WA2 of the outer panel PNL2. It can be a flexible structure. When the display panel PNL is in the unfolded state, the second sub-driver DP2 can extend along the extension direction of the inner panel PNL1. The second sub-driver DP2 and the display panel PNL can be an integrated flexible structure, or the second sub-driver DP2 can be a flexible circuit board provided independently of the inner panel PNL1. In the deformed state, the second sub-driver DP2 can bend toward the non-luminescent side of the outer panel PNL2.

[0138] The second sub-driving part DP2 may include a second driving chip DC2, and the second peripheral circuit of the outer panel PNL2 may be connected to the second driving chip DC2, so that the second peripheral circuit may be controlled by the second driving chip DC2 to output a driving signal, so that the outer panel PNL2 displays an image.

[0139] As shown in Figure 19, in some embodiments, the first sub-driving part DP1, the second sub-driving part DP2 and the gap GA are distributed along a straight line passing through the center of the inner panel PNL; alternatively, the first sub-driving part DP1, the second sub-driving part DP2 and the gap GA may also be distributed along the circumference of the inner panel PNL, and at most two of the first sub-driving part DP1, the second sub-driving part DP2 and the gap GA are distributed along a straight line passing through the center of the inner panel PNL.

[0140] Furthermore, as shown in FIG19 , the first sub-driver DP1 can extend into the gap GA, fully utilizing the space within the gap GA to accommodate the first sub-driver DP1, thereby reducing the gap between the inner panel PNL1 and the outer panel PNL2. Alternatively, the first sub-driver DP1 and the gap GA can be spaced apart along the circumference of the inner panel PNL1, such that the first sub-driver DP1 is located between the inner panel PNL1 and the outer panel PNL2. The gap between the inner panel PNL1 and the outer panel PNL2 should be sufficient to accommodate the first sub-driver DP1.

[0141] In some embodiments, as shown in FIG. 20 , in a deformed state, the first sub-driving portion DP1 bends toward the non-luminescent side of the inner panel PNL1. The first sub-driving portion DP1 may include a third bent portion BP3 and a third extending portion FP3. The third bent portion BP3 may connect the inner panel PNL1 and the third extending portion FP3. The third bent portion BP3 bends toward the non-luminescent side of the inner panel PNL1 and may have an arc shape. The third extending portion FP3 may extend along the extension direction of the inner panel PNL1. A gasket SG may be disposed between the third extending portion FP3 and the inner panel PNL1 to support the third extending portion FP3. Furthermore, the gasket SG may be bonded to the third extending portion FP3 via a glue layer GL.

[0142] In the deformed state, as shown in Figure 21, the second sub-driving part DP2 bends toward the non-luminous side of the outer panel PNL2 and includes a first bent portion BP1 and a first extending portion FP1. The first bent portion BP1 connects the outer panel PNL2 and the first extending portion FP1. The first bent portion BP1 may bend toward the non-luminous side of the outer panel PNL2 and may have an arc shape. The first extending portion FP1 extends along the extending direction of the outer panel PNL2.

[0143] As shown in Figure 21, the second sub-driving unit DP2 may further include a second bent portion BP2 and a second extending portion FP2. The second bent portion BP2 connects the first extending portion FP1 and the second extending portion FP2. The second bent portion BP2 corresponds to the area between the inner panel PNL1 and the outer panel PNL2 and may bend toward the non-luminescent side of the display panel PNL. The second extending portion FP2 may extend in the direction of extension of the inner panel PNL1, extending the second sub-driving unit DP2 to the non-luminescent side of the inner panel PNL1. Furthermore, a gasket SG may be provided between the second extending portion FP2 and the outer panel PNL2, and between the second extending portion FP2 and the inner panel PNL1. The gasket SG supports the second sub-driving unit DP2. Furthermore, the gasket SG may be bonded to the second extending portion FP2 via an adhesive layer GL, and the gasket SG corresponding to the first extending portion FP1 may be bonded to the first extending portion FP1 via another adhesive layer GL.

[0144] Of course, in other embodiments, the second sub-driving part DP2 may not have the second bent portion BP2 and the second extending portion FP2, and the first extending portion FP1 may extend along the extending direction of the inner panel PNL1.

[0145] Based on the second embodiment described above, in some embodiments of the present disclosure, the transparent cover plate CG may include a central portion CG1 covering the inner panel PNL1, a transition portion CG2 covering the area between the inner panel PNL1 and the outer panel PNL2, and an edge portion CG3 that curves toward the non-luminous side of the display panel PNL. The specific structure can be referenced above with respect to the transparent cover plate CG in the first embodiment and will not be described in detail here. In the deformed state, the first sub-driver DP1 is not in contact with the transition portion CG2 and the edge portion CG3, but remains covered. Specifically, the orthographic projection of the first sub-driver DP1 on a plane parallel to the central portion CG1 lies within the range of the orthographic projection of the transparent cover plate CG on the same plane. The second extension portion FP2 of the second sub-driver DP2 may be attached to the edge portion CG3.

[0146] In some embodiments of the present disclosure, a light absorbing layer BM may be provided between the transparent cover plate CG and the display panel PNL. The light absorbing layer BM may include a first light absorbing portion BM1, a second light absorbing portion BM2, and further include a third light absorbing portion BM3 and a fourth light absorbing portion BM4. The specific structure of the light absorbing layer BM can refer to the light absorbing layer BM of the first embodiment. As long as it covers the area between the inner panel PNL1 and the outer surface and the edge of the outer panel PNL2, it will not be described in detail here.

[0147] The present disclosure also provides a terminal device, which may include a display device of any of the above-mentioned embodiments. The specific structure of the display device can refer to the first and second embodiments above, which will not be repeated here. At the same time, the terminal device may also include a control mainboard, which can be connected to the driving unit DP, and is used to control the display panel PNL to display images through the driving unit DP. The control mainboard may include a processor and a memory, etc. The processor may include an image processing circuit, which can transmit data to the driving chip DC of the driving unit DP. Of course, the image processing circuit can also be an independent chip provided on the control mainboard, which can be connected to the processor. For the second embodiment above, the control mainboard can be connected to the first sub-driving unit DP1 and the second sub-driving unit DP2 at the same time.

[0148] The terminal device disclosed in the present invention can be a wearable device such as a smart watch or smart glasses. Of course, it can also be other devices that can display images. Its application scenarios are not particularly limited here.

[0149] Those skilled in the art will readily appreciate other embodiments of the present disclosure after considering the specification and practicing the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art not disclosed herein.
