It should be understood that the specific embodiments described herein are only configured to explain the present application and are not configured to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present application by illustrating the examples of the present application.

[0035] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0037] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0038] Wearable devices are portable devices that can be worn directly on the human body. These devices include flexible sensing and display devices. Their flexibility allows them to conform to the human body, making them comfortable to wear and easy to carry. Flexible sensing and display devices in related technologies can collect information such as physical and biological parameters. However, existing flexible sensing and display devices cannot simultaneously generate light and display information, limiting their application scenarios.

[0039] To solve the above problems, the present application proposes a flexible sensing display device and a wearable device. The flexible sensing display device of an embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0040] like Figure 1 As shown, a flexible sensing display device includes a display line 1 and a sensing line 2. The display line 1 includes a flexible conductive core line 11, at least one conductive winding 12 and at least one flexible light-emitting element 13. The conductive winding 12 is spirally wound on the outside of the flexible conductive core line 11. The flexible light-emitting element 13 is electrically connected to the flexible conductive core line 11 and the conductive winding 12 respectively; the sensing line 2 is connected to the flexible conductive core line 11.

[0041] Both the flexible conductive core 11 and the conductive winding 12 are flexible, allowing the conductive winding 12 to be spirally wound around the outside of the flexible conductive core 11. The flexible conductive core 11 and the conductive winding 12 can be bent as needed. The conductive winding 12 is wound around the outside of the flexible conductive core 11, so that the flexible conductive core 11 can serve as a support for the conductive winding 12. In the case of multiple conductive windings 12, multiple conductive windings 12 can be wound around the flexible conductive core 11. The outside of the conductive winding 12 and / or the flexible conductive core 11 can be coated with an insulating material to insulate the conductive winding 12 and the flexible conductive core 11 that are in contact with each other.

[0042] The flexible light-emitting element 13 is a device that can be bent and can perform photoelectric conversion. The flexible light-emitting element 13 can be set as an organic light-emitting diode (OLED). Alternatively, the flexible light-emitting element 13 can be set as a micro light-emitting diode (Micro-LED) or a quantum dot light-emitting diode (QLED). The flexible light-emitting element 13 is electrically connected to the flexible conductive core 11 and the conductive winding 12 respectively, so that the flexible conductive core 11 and the conductive winding 12 can control whether the flexible light-emitting element 13 is powered and the power-on duration, so as to realize the light display of the flexible light-emitting element 13.

[0043] The sensing line 2 is a flexible linear structure provided with a sensing material. One or more sensing structures can be provided in the sensing line 2 so that the sensing line 2 can collect the required physical information or biological information.

[0044] In the embodiment provided in the present application, by setting a display line 1 and a sensing line 2, the flexible sensing display device can perform luminous display and information collection; by setting a flexible conductive core line 11 and a conductive winding 12 wound around the flexible conductive core line 11, the display line 1 is made flexible; by setting a flexible light-emitting element 13 electrically connected to the flexible conductive core line 11 and the conductive winding 12 respectively, the flexible light-emitting element 13 can be controlled to emit light by controlling whether the flexible conductive core line 11 and the conductive winding 12 are energized.

[0045] See also Figure 2 and Figure 3 In some embodiments, the flexible conductive core wire 11 includes a first conductive core 111 and a first insulating layer 112 wrapped around the outside of the first conductive core 111, the conductive winding 12 includes a second conductive core 121 and a second insulating layer 123 wrapped around the outside of the second conductive core 121, and the flexible light-emitting element 13 is connected to the first conductive core 111 and the second conductive core 121.

[0046] like Figure 2As shown, the area where the flexible conductive core 11 contacts the conductive winding 12 is separated by the first insulating layer 112 and the second insulating layer 123, so that the first conductive core 111 and the second conductive core 121 can be insulated from each other in the area where the flexible conductive core 11 contacts the conductive winding 12. Figure 3 As shown, the first insulating layer 112 has at least one first opening exposing the first conductive core 111, the second insulating layer 123 has at least one second opening exposing the second conductive core 121, and the flexible light-emitting element 13 is connected to the first conductive core 111 exposed in the first opening and the second conductive core 121 exposed in the second opening.

[0047] Both the first conductive core 111 and the second conductive core 121 are made of a conductive material, such as a metal conductive material, a carbon fiber conductive material, or a polymer conductive material. Optionally, the first conductive core 111 is a bundle of conductive silver wires composed of multiple conductive fibers, and the second conductive core 121 is a bundle of conductive silver wires composed of multiple conductive fibers. The first insulating layer 112 and the second insulating layer 123 are both made of an insulating material. Optionally, both the first insulating layer 112 and the second insulating layer 123 are polyurethane resin.

[0048] In some embodiments, the flexible light-emitting member 13 is an electroluminescent film, which is sandwiched between the first conductive core 111 and the second conductive core 121 .

[0049] The electroluminescent film is a thin-film layer made of electroluminescent materials. Opposite sides of the electroluminescent film are connected to the first conductive core 111 and the second conductive core 121, respectively. Under the influence of the electric field generated by the first and second conductive cores 111 and 121, the electroluminescent film emits light waves. The electroluminescent film is flexible, allowing it to be bent as needed.

[0050] In some embodiments, the electroluminescent film includes a substrate 131 and electroluminescent particles 132 . The electroluminescent particles 132 are distributed in the substrate 131 . The substrate 131 adheres the flexible conductive core 11 and the conductive winding 12 .

[0051] The substrate 131 is used to support the electroluminescent particles 132 and bond the flexible conductive core 11 and the conductive winding 12, thereby eliminating the need for additional conductive material to connect the electroluminescent film to the flexible conductive core 11, and vice versa. The substrate 131 can be a transparent polymer material to allow the electroluminescent particles 132 to be evenly dispersed in the substrate 131. Alternatively, the substrate 131 is a polyurethane resin, and the electroluminescent particles 132 are zinc sulfide mixed in the polyurethane resin.

[0052] In some embodiments, the diameter of the flexible conductive core wire 11 is greater than the diameter of the conductive winding wire 12 .

[0053] The diameter of the flexible conductive core 11 is larger than that of the conductive winding 12, which provides the flexible conductive core 11 with better support than the conductive winding 12. The diameter of the flexible conductive core 11 is smaller than that of the conductive winding 12, which provides the conductive winding 12 with better bendability than the flexible conductive core 11, making it more suitable for the conductive winding 12 to be wound around the flexible conductive core 11.

[0054] In some embodiments, the thickness H3 of the first insulating layer 112 is the same as the thickness H4 of the second insulating layer 123. The diameter H1 of the first conductive core 111 is 100D to 400D, and the diameter H2 of the second conductive core 121 is 40D to 200D. Optionally, the diameter H1 of the first conductive core 111 is 200D, and the diameter H2 of the second conductive core 121 is 70D.

[0055] See also Figure 4 In some embodiments, there are multiple conductive windings 12 and multiple flexible light-emitting components 13. The multiple conductive windings 12 are sequentially wound around the outside of the flexible conductive core wire 11. The multiple conductive windings 12 are alternately arranged along the length direction of the flexible conductive core wire 11. The multiple flexible light-emitting components 13 are electrically connected to the multiple conductive windings 12 one by one.

[0056] When there are multiple conductive windings 12, the multiple conductive windings 12 are wound around the flexible conductive core 11 starting from one end of the flexible conductive core 11. A first conductive winding 12R among the multiple conductive windings 12 is spirally wound around the flexible conductive core 11 to form first curved segments spaced apart along the length of the flexible conductive core 11. A second conductive winding 12G among the multiple conductive windings 12 is spirally wound around the flexible conductive core 11 to form second curved segments spaced apart along the length of the flexible conductive core 11, with the second curved segments located between two adjacent first curved segments. A third conductive winding 12B among the multiple conductive windings 12 is spirally wound around the flexible conductive core 11 to form third curved segments spaced apart along the length of the flexible conductive core 11, with the third curved segments located between adjacent first and second curved segments. A fourth conductive winding 12 among the multiple conductive windings 12 is spirally wound around the flexible conductive core 11 to form fourth curved segments spaced apart along the length of the flexible conductive core 11, with the fourth curved segments located between adjacent first and third curved segments. If the plurality of conductive windings 12 further include a fifth conductive winding, a sixth conductive winding, a seventh conductive winding, etc., and so on, the conductive windings 12 formed are alternately arranged along the length direction of the flexible conductive core wire 11, which will not be repeated here.

[0057] Multiple flexible light-emitting elements 13 are electrically connected to multiple conductive windings 12 one by one, so that by controlling whether each conductive winding 12 is energized, the flexible light-emitting elements 13 connected one by one to the conductive winding 12 can be controlled to emit light, so that the display line 1 can achieve complex display lighting.

[0058] In some embodiments, at least two flexible light-emitting members 13 among the plurality of flexible light-emitting members 13 emit light waves with different wavelengths.

[0059] By setting the wavelengths of light waves emitted by at least two flexible light-emitting members 13 to be different, the flexible light-emitting members 13 capable of emitting light waves of different wavelengths can be controlled to emit light waves of different colors by controlling whether the conductive winding 12 is energized, so that the display line 1 can achieve complex display lighting.

[0060] In some embodiments, the plurality of flexible light-emitting elements 13 include a first light-emitting element 13R capable of emitting a first color light wave, a second light-emitting element 13G capable of emitting a second color light wave, and a third light-emitting element 13B capable of emitting a third color light wave. The plurality of conductive windings 12 include a first conductive winding 12R, a second conductive winding 12G, and a third conductive winding 12B. The first conductive winding 12R, the second conductive winding 12G, and the third conductive winding 12B are alternately spirally wound around the flexible conductive core 11. The end of the first conductive winding 12R is connected to the first light-emitting element 13R, the end of the second conductive winding 12G is connected to the second light-emitting element 13G, and the end of the third conductive winding 12B is connected to the third light-emitting element 13B. The first light-emitting element 13R, the second light-emitting element 13G, and the third light-emitting element 13B are arranged sequentially along the length of the flexible conductive core 11.

[0061] See also Figure 5 In another embodiment, the multiple flexible light-emitting members 13 include multiple first light-emitting members 13R, multiple second light-emitting members 13G, and multiple third light-emitting members 13B. The multiple first light-emitting members 13R are arranged at intervals along the length direction of the flexible conductive core 11 and are respectively electrically connected to the same first conductive winding 12R. The multiple second light-emitting members 13G are arranged at intervals along the length direction of the flexible conductive core 11 and are respectively electrically connected to the same second conductive winding 12G. The multiple third light-emitting members 13B are arranged at intervals along the length direction of the flexible conductive core 11 and are respectively electrically connected to the same third conductive winding 12B. The order of arrangement of the multiple first light-emitting members 13R, the multiple second light-emitting members 13G, and the multiple third light-emitting members 13B along the length direction of the flexible conductive core 11 can be set as needed in the art.

[0062] When the flexible line and the display line 1 are connected end to end in a ring shape, multiple first light-emitting elements 13R, multiple second light-emitting elements 13G and multiple third light-emitting elements 13B are provided, so that light-emitting elements of any color among the multiple first light-emitting elements 13R, multiple second light-emitting elements 13G and multiple third light-emitting elements 13B can emit light at the same time, so that the ring-shaped flexible sensing display device emits light in a ring shape.

[0063] Optionally, the first light-emitting element 13R is a red light-emitting element capable of emitting red light, the second light-emitting element 13G is a green light-emitting element capable of emitting green light, and the third light-emitting element 13B is a blue light-emitting element capable of emitting blue light. The first light-emitting element 13R, the second light-emitting element 13G, and the third light-emitting element 13B can be configured to have different luminous areas as needed. Optionally, the luminous surfaces of the first light-emitting element 13R, the second light-emitting element 13G, and the third light-emitting element 13B are all rectangular, 2 mm long and 1 mm wide. Adjacent flexible light-emitting elements 13 are spaced 1 cm apart.

[0064] In some embodiments, the sensing line 2 includes at least one of the following:

[0065] Temperature sensors, humidity sensors, pressure sensors, stress sensors, biological information collection devices, and gas detection devices.

[0066] Those skilled in the art can determine which sensing elements to include in the sensing cable 2 based on the information to be collected by the flexible sensing display device. For example, the sensing cable 2 includes a biometric information collection element for collecting heart rate information, which includes a photoelectric sensor. The flexible light-emitting element 13 emits light waves, which are reflected by the skin and then reflected by the photoelectric sensor. The photoelectric sensor converts the received light signal into an electrical signal, which is then analyzed to obtain heart rate information.

[0067] Please refer to Figure 5 、 Figure 6 and Figure 7 In some embodiments, the sensing line 2 includes an elastic core 21, a sensing layer 22, an electrical connection part 23 and a packaging layer 24. The sensing layer 22 is coated on the outside of the elastic core 21. The electrical connection part 23 connects the sensing layer 22 and the flexible conductive core line 11. The packaging layer 24 is coated on the outside of the sensing layer 22 and the electrical connection part 23.

[0068] The elastic core 21 is not only elastic but also flexible, so that the elastic core 21 can be stretched and bent. Optionally, the elastic core 21 is made of elastic spandex yarn.

[0069] Sensing layer 22 is the primary functional layer for signal acquisition. Depending on the information being collected, sensing layer 22 may have different materials and structures. Optionally, sensing layer 22 may be made of one or more of a carbonaceous material, a MXene material, or a metal material.

[0070] The electrical connector 23 connects the sensing layer 22 and the flexible conductive core 11, thereby providing power to the sensing layer 22 through the electrical connector 23. The electrical connector 23 can be linear, and those skilled in the art can adjust the length of the electrical connector 23 based on the desired length of the sensing line 2. The electrical connector 23 can be connected to both ends of the first conductive core using a fiber joint method such as a woven knot, a self-tightening knot, a single shackle, or a double shackle. The diameter of the electrical connector 23 can be consistent with the diameter of the elastic core 21 covering the sensing layer 22 to ensure a smooth outer surface of the prepared sensing line 2.

[0071] Encapsulation layer 24 is made of an elastic, flexible, and insulating material, allowing it to stretch and bend along with elastic core 21. Furthermore, encapsulation layer 24 prevents electrical connection between sensing layer 22 and electrical connection portion 23 and undesired conductive structures. Optionally, encapsulation layer 24 is made of polydimethylsiloxane (PDMS).

[0072] For example, the sensing line 2 includes a stress sensor for collecting stress. This stress sensor is a carbon nanotube sensing layer 22. When the sensing line 2 is attached to the user's skin, the user's movements cause the sensing layer 22 to stretch or contract with the skin, causing the resistance of the carbon nanotubes to change. This changes the electrical signal generated by the sensing line 2, and analysis of this signal can reveal stress information.

[0073] In a second aspect, an embodiment of the present application further provides a wearable device, comprising: a control chip and a flexible sensing display device as provided in the first aspect; the control chip is electrically connected to the flexible sensing display device.

[0074] The driving chip may include a data transmission unit and a control unit. The data transmission unit is electrically connected to the sensing line and configured to receive the electrical signal collected by the sensing line; the control unit is signal-connected to the data transmission unit and configured to process the electrical signal sent by the data transmission unit and control the display line 1 to emit light according to the electrical signal.

[0075] In the case where the display line 1 has a plurality of flexible light-emitting devices, the control unit is configured to control each flexible light-emitting device to perform independent display according to the electrical signal.

[0076] In the wearable device provided in the embodiment of the present application, the relevant structure of the flexible sensing display device described above can be referred to the flexible sensing display device provided in the above embodiments. It has all the beneficial effects of the flexible sensing display device described above and will not be repeated here.

[0077] In one embodiment, the wearable device is a textile, and the wearable device further includes a braided wire, which may be a cotton wire, a wool wire, etc. The braided wire and the linear flexible sensing display device may be connected together by braiding, knitting, sewing, etc.

[0078] Experimental Example 1: Preparation of display lines.

[0079] A conductive silver wire with a diameter of 200D is provided as a first conductive core, and a 50 μm layer of polyurethane resin is coated on the outside of the conductive silver wire to form a first insulating layer covering the outside of the first conductive core, thereby preparing a flexible conductive core wire;

[0080] Providing a conductive silver wire with a diameter of 70D as the second conductive core, coating the outer side of the conductive silver wire with a 50 μm thickness of polyurethane resin to form a second insulating layer covering the outer side of the second conductive core, thereby preparing a conductive winding;

[0082] Providing a polyurethane resin and zinc sulfide (ZnS) powder, and mixing the polyurethane resin and the zinc sulfide powder in a mass ratio of 2:1 to obtain an electroluminescent solution;

[0083] An electroluminescent solution is coated on the end of the conductive winding where the second conductive core is exposed. The viscosity of the polyurethane resin in the electroluminescent solution is used to bond the second conductive core of the conductive winding and the first conductive core of the flexible conductive core wire together to form a stacked structure of the second conductive core, the electroluminescent layer, and the first conductive core to prepare a display line.

[0084] See also Figure 8 , is an electron microscope image of the second conductive core spirally wound on the outer side of the flexible conductive core wire prepared in Example 1.

[0085] Experimental Example 2: Preparation of sensing wires.

[0086] 0.12 g of sodium dodecylbenzenesulfonate was dissolved and dispersed in 29.7 mL of deionized water, and 0.3 g of multi-walled carbon nanotubes was added to the solution and mixed to prepare a carbon nanotube (CNT) dipping solution;

[0087] Providing a spandex yarn with a diameter of 420D, placing the spandex yarn in a carbon nanotube dipping solution, dipping and drying the solution, and repeating this process three times;

[0088] Provide a conductive silver wire, cut the spandex yarn coated with carbon nanotubes into 2 cm long segments, and use conductive silver paste to bond and solidify the two ends of the segment to the two ends of the conductive silver wire respectively;

[0089] Polydimethylsiloxane is encapsulated on the spandex yarn, the cured conductive silver paste and the outside of the conductive silver wire to prepare a sensing wire.

[0090] See also Figure 9 , is a cross-sectional electron microscope image of the sensor wire prepared in Example 2.

[0091] Experimental Example 3: Preparation of a flexible sensing display device.

[0092] Processing the prepared display lines and sensing lines so that the ends of the first conductive cores are exposed and the conductive silver wires in the sensing lines are exposed;

[0093] The exposed first conductive core and the exposed conductive silver wire are knotted into a woven knot, so that the exposed first conductive core and the exposed conductive silver wire are electrically connected, thereby preparing a ring-shaped flexible sensing display device.

[0094] The following experiments were conducted using the flexible sensing display device prepared in Experimental Example 3:

[0095] The flexible sensor display device is stretched to change the stress of the sensing line and detect the resistance change of the sensing layer. Figure 10 As shown in the figure, the horizontal axis is the strain value of the sensing line, and the vertical axis is the resistance change rate of the sensing layer. The strain value is the stretched length of the sensing line divided by the initial length. The resistance change rate is the resistance change value of the sensing layer divided by the initial resistance value.

[0096] from Figure 10 It can be seen that as the stress of the sensing line gradually increases, the resistance of the sensing layer gradually increases. Therefore, the flexible sensing display device prepared in Experimental Example 3 has good sensing performance when the stress change of the sensing line is within 40%.

[0097] The flexible sensor display device is stretched and contracted back and forth, causing the stress of the sensing line to alternately increase and decrease, and detecting the resistance change of the sensing layer. Figure 11 As shown in the figure, the horizontal axis is time, the vertical axis is the resistance change rate of the sensing layer, and the strain value is marked in the dashed box. The strain value is the initial length of the sensing wire divided by the length after stretching. The resistance change rate is the resistance change value of the sensing layer divided by the initial resistance value.

[0098] from Figure 11 It can be seen from the graph that under the alternating stress changes of the sensing line, the resistance of the sensing layer can change stably and cyclically.
