[0050] In the current technical solutions, for electronic fabrics, light-emitting devices such as light-emitting diodes are mainly fabricated on the fabric surface through methods such as patch welding, or the display of the fabric is achieved by mixing and weaving light-emitting fibers and conductive fibers. Since the display is a passive array, the image resolution is low and the refresh rate is slow.

[0051] A woven display device and a preparation method thereof provided by the present application aim to solve the above technical problems in the prior art. The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific embodiments.

[0052] In a first aspect, an embodiment of the present application provides a woven display device. As Figure 1 shown, Figure 1 is a schematic structural diagram of a woven display device in an embodiment of the present application.

[0053] A woven display device includes:

[0054] A flexible substrate 101, including at least two strip structures 101a located in the display area; the strip structure includes a stacked substrate layer and a transistor layer;

[0055] Light-emitting fibers 201, electrically connected to the transistor layer;

[0056] Wherein, the light-emitting fibers 201 are interwoven with at least part of the strip structures 101a to form a shape.

[0057] By providing a transistor layer and light-emitting fibers in the embodiment of the present application, the flexible substrate and the light-emitting fibers are interwoven to form a shape, and an active light-emitting array is used to replace the passive array display in the prior art, improving the display quality of the woven display device, displaying dynamic images on the woven display device, increasing the amount of information displayed by the woven display device, and improving the personalization and customization of the woven display device.

[0058] As Figure 2 and Figure 3 shown, Figure 2 is Figure 1 the cross-sectional view of A-A' in Figure 3 is Figure 1 the cross-sectional view of B-B' in

[0059] In some embodiments of the present invention, the light-emitting fibers 201 include: a first sub-fiber 201a, a first conductive coating 201b coated on the surface of the first sub-fiber 201a, and a light-emitting structure 201c coated on at least part of the surface of the first conductive coating 201b.

[0060] In some embodiments, the first sub-fiber 201a is a fabric fiber, which is both flexible and tough, but generally an insulating material. To make the light-emitting fiber 201 conductive, a first conductive coating 201b is coated or ink-jet printed on the surface of the fabric fiber. The material of the first conductive coating 201b includes at least one of copper, aluminum, silver, nickel, conductive plastic, conductive rubber, and conductive glass.

[0061] In one embodiment, the material of the first conductive coating 201b includes metallic elements such as copper, aluminum, silver, nickel or alloy materials. The first conductive coating 201b has excellent electrical conductivity, fast signal transmission speed, and the woven display device responds quickly;

[0062] In another embodiment, the material of the first conductive coating 20b includes conductive glass. The first conductive coating 201b has a higher light transmittance, the light-emitting efficiency of the woven display device is higher, and the display effect is better.

[0063] To enable the woven display device to have a display function, the light-emitting fiber 201 needs to have a light-emitting function. A light-emitting structure 201c is prepared on a part or all of the surface of the first conductive coating 201b. The light-emitting structure 201c includes an electron injection layer, an electron transport layer, a light-emitting material layer, a hole transport layer, and a hole injection layer.

[0064] In some embodiments of the present invention, the light-emitting structure includes an organic light-emitting diode or a quantum dot light-emitting diode.

[0065] In one embodiment, the light-emitting material layer includes a fluorescent material and a phosphorescent material; in another embodiment, the light-emitting material layer includes a light-emitting material doped with quantum dots. The light-emitting structure 201c is electrically connected to the transistor layer through an electrode, so as to realize the self-luminescence of the light-emitting fiber 201 and the active display of the woven display device.

[0066] In some embodiments of the present invention, the woven display device further includes a signal fiber 202, and the signal fiber 202 is interwoven with at least a part of the strip-shaped structure 101a.

[0067] In some embodiments of the present invention, the signal fiber 202 includes: a second sub-fiber 202a and a second conductive coating 202b coated on the surface of the second sub-fiber 202a. The second conductive coating 202b is electrically connected to the transistor layer.

[0068] In some embodiments, similar to the light-emitting fiber 201, the second sub-fiber 202a is a fabric fiber. A second conductive coating 202b is coated or ink-jet printed on the surface of the fabric fiber. The material of the first conductive coating 202b includes at least one of copper, aluminum, silver, nickel, conductive plastic, conductive rubber, and conductive glass.

[0069] However, different from the light-emitting fiber 201, in some other embodiments, the signal fiber 202 is a nanofiber material, and the second sub-fiber 202a wraps a nanoscale conductive core to synthesize a conductive signal fiber 202.

[0070] The second conductive coating 202b or the nanoscale conductive core is electrically connected to the transistor layer, and the transistor layer indirectly transmits data signals or scan signals to the light-emitting fiber 201 through the signal fiber 202 to control the light-emitting fiber 201.

[0071] In this embodiment, the signal fiber 202 is parallel to the light-emitting fiber 201, and the signal fiber 202 also interweaves with at least part of the strip structure.

[0072] In some embodiments of the present invention, the woven display device further includes a positive power supply line (VDD) and a negative power supply line (VSS);

[0073] The positive power supply line is connected to the flexible substrate 101, and the negative power supply line is connected to the first conductive coating 201b; or, the positive power supply line is connected to the first conductive coating 201b, and the negative power supply line is connected to the flexible substrate 101.

[0074] In one embodiment, the transistor layer includes a source electrode and a drain electrode. The positive power supply line is directly connected to the drain electrode of the transistor layer on the flexible substrate 101, and the negative power supply line is indirectly connected to the source electrode of the transistor layer on the flexible substrate 101 through the first conductive coating 201b of the light-emitting fiber 201.

[0075] In another embodiment, the transistor layer includes a source electrode and a drain electrode. The negative power supply line is directly connected to the source electrode of the transistor layer on the flexible substrate 101, and the positive power supply line is indirectly connected to the drain electrode of the transistor layer on the flexible substrate 101 through the first conductive coating 201b of the light-emitting fiber 201.

[0076] In some embodiments of the present invention, the woven display device further includes a signal line (not shown in the figure), the signal line is disposed on the strip structure 101a, and the signal fiber 201 intersects with the signal line;

[0077] The signal fiber 202 carries a scan signal, and the signal line carries a data signal; or, the signal fiber 202 carries a data signal, and the signal line carries a scan signal.

[0078] Such as Figure 4 and Figure 5 shown, Figure 4 is a schematic diagram of a pixel array in an embodiment of the present invention, Figure 5 is a schematic diagram of a pixel array in another embodiment of the present invention.

[0079] In one embodiment, the number of signal lines is half the number of strip structures 101a. The strip structures 101a are divided into a pixel region and a non-pixel region, and the pixel region and the non-pixel region are arranged alternately. Among them, the strip structures 101a provided with signal lines are pixel regions, and the strip structures 101a without signal lines are non-pixel regions. The light-emitting sides of the pixel regions are on the same side of the flexible substrate 101, so the woven display device is a single-sided display.

[0080] In another embodiment, the number of signal lines is equal to the number of strip structures 101a, and signal lines are provided on each strip structure 101a. Then, all the strip structures 101a are pixel regions, but they can be classified according to the different light-emitting sides of the pixel regions. The pixel regions with the light-emitting sides on the first side of the flexible substrate 101 are the first pixel regions, and the pixel regions with the light-emitting sides on the second side of the flexible substrate 101 are the second pixel regions. The first pixel regions and the second pixel regions are arranged alternately. The woven display device can display on both the first side and the second side, thus realizing double-sided display.

[0081] As Figure 2 and Figure 3 shown, in some embodiments of the present invention, a part of the light-emitting fibers 201 and another part of the light-emitting fibers 201 are respectively arranged on both sides of the flexible substrate 101; and / or, a part of the signal fibers 202 and another part of the signal fibers 202 are respectively arranged on both sides of the flexible substrate 101.

[0082] In this embodiment, the first part 2011 of the light-emitting fiber 201 and the first part 2021 of the signal fiber 202 are the first pixel regions, and emit light and display on the first side of the flexible substrate 101; the second part 2012 of the light-emitting fiber 201 and the second part 2022 of the signal fiber 202 are the second pixel regions, and emit light and display on the second side of the flexible substrate 101.

[0083] In some embodiments of the present invention, the woven display device further includes a signal input electrode and a voltage output electrode. The signal input electrode is in contact with the signal fiber 202, and the voltage output electrode is in contact with the light-emitting fiber 201;

[0084] Among them, the contact points between a part of the signal fibers 202 and the signal input electrode are located between the signal fibers 202 and the flexible substrate 101, and the contact points between a part of the light-emitting fibers 201 and the voltage output electrode are located between the light-emitting fibers 201 and the flexible substrate 101; and / or, the contact points between another part of the signal fibers 202 and the signal input electrode are located on the side of the flexible substrate 101 away from the signal fibers 202, and the contact points between another part of the light-emitting fibers 201 and the voltage output electrode are located on the side of the flexible substrate 101 away from the light-emitting fibers 201.

[0085] In this embodiment, the first part 2011 of the light-emitting fiber 201 and the second part 2012 of the light-emitting fiber 201 disposed on different sides of the flexible substrate 101 have similar structures and share part of the structure, but the differences at least include that the contact points of the two with the voltage output electrode 302 are different. On the first side of the flexible substrate 101, the voltage output electrode 302 at the contact point is on the upper surface of the flexible substrate 101, the first part 2011 of the light-emitting fiber 201 is on the voltage output electrode 302 at this position, and the first conductive coating 201b in the first part 2011 of the light-emitting fiber 201 that is not covered by the light-emitting structure is in direct contact with the voltage output electrode 302; on the second side of the flexible substrate 101, the voltage output electrode 302 at the contact point is on the upper surface of the flexible substrate 101, the second part 2012 of the light-emitting fiber 201 is on the lower surface of the flexible substrate 101, that is, on the second side of the flexible substrate 101, the second part 2012 of the light-emitting fiber 201 and the voltage output electrode 302 are respectively located on both sides of the flexible substrate 101, and the conductive coating of the second part 2012 of the light-emitting fiber 201 needs to be electrically connected to the voltage output electrode 302 through the through hole on the flexible substrate 101 or the side surface of the flexible substrate 101. Sharing part of the structure can reduce the repeated arrangement of devices and is beneficial to the thinning of the woven display device, and the different contact points on different sides of the flexible substrate 101 are beneficial to enhancing the stability of the contact points. It can be understood that only the contact points of the light-emitting fiber 201 and the voltage output electrode 302 are taken as examples here. In fact, in some embodiments, the contact points of the first part 2021 of the signal fiber 202, the second part 2022 of the signal fiber 202 and the signal input electrode 301, and the contact points of some of the insulating fibers 203 and the pixel circuit 303 are the same as above and will not be elaborated.

[0086] In some embodiments of the present invention, the woven display device further includes insulating fibers 203, and at least one signal fiber 202 or at least one light-emitting fiber 201 is located between two adjacent insulating fibers 203.

[0087] In this embodiment, in order to avoid interference between the signal fiber 202 and the signal fiber 202, the signal fiber 202 and the light-emitting fiber 201, and the light-emitting fiber 201 and the light-emitting fiber 201, insulating fibers 203 are provided between the signal fiber 202 and the signal fiber 202, the signal fiber 202 and the light-emitting fiber 201, and the light-emitting fiber 201 and the light-emitting fiber 201, and the insulating fibers 203 are also interwoven with the strip structure 101a to form a shape.

[0088] In a specific embodiment, the shape of the strip structure 101a is rectangular, and the shapes of the light-emitting fiber 201, the signal fiber 202, and the insulating fiber 203 are also rectangular. The insulating fiber 203 is parallel to the signal fiber 202 and the light-emitting fiber 201 and perpendicular to the strip structure 101a. The strip structure 101a extends in the horizontal direction in the figure, and the light-emitting fiber 201, the signal fiber 202, and the insulating fiber 203 extend in the vertical direction in the figure, intersecting with each other to form a mesh structure.

[0089] In other embodiments, the shape of the strip structure 101a can be wavy or W-shaped.

[0090] In some embodiments, the light-emitting fiber 201 includes a red light-emitting fiber, a green light-emitting fiber, and a blue light-emitting fiber. By adjusting the contact area between the voltage output electrode 302 and the light-emitting fiber 201, parameters such as the brightness of the light-emitting fiber 201 can be controlled. In a specific embodiment, the light-emitting fiber 201 uses a fluorescent light-emitting material. Since the decay of the blue fluorescent material is faster than that of the green fluorescent material and the red fluorescent material, the contact area between the blue light-emitting fiber and the voltage output electrode 302 is larger than the contact areas between the red light-emitting fiber, the green light-emitting fiber and the voltage output electrode 302. Thus, there is always enough blue light in the mixed white light.

[0091] As Figure 6 shown, Figure 6 is a schematic structural diagram of a bonding area in an embodiment of the present invention.

[0092] In some embodiments of the present invention, the woven display device further includes a driving chip 401, and the driving chip 401 is electrically connected to the flexible substrate 101 through a flexible circuit board 402 and a flexible terminal 403 in sequence.

[0093] In this embodiment, the packaging method of the driving chip 401 is a flip chip on film. The driving chip 401 is bent to the back of the flexible substrate 101 to ensure the front screen ratio of the woven display device and achieve a narrow border effect.

[0094] Based on the same inventive concept, in a second aspect, an embodiment of the present application provides a preparation method of a woven display device, as Figure 7 and Figures 8A to 8E shown, Figure 7 is a flowchart of the preparation method in an embodiment of the present invention, Figures 8A to 8E is a step-by-step schematic diagram of the preparation method in an embodiment of the present invention.

[0095] A preparation method of a woven display device includes the following steps:

[0097] S2. Cut the flexible substrate 101 to form at least two strip structures 101a, as Figure 8B shown;

[0098] S3. Coat a first conductive coating 201b and a light-emitting structure 201c on the first sub-fiber 201a to form a light-emitting fiber 201, as Figure 8C and Figure 8D shown;

[0099] S4. Interweave the light-emitting fiber 201 with at least part of the strip structures 101a and electrically connect the light-emitting fiber 101 to the transistor layer of the strip structure 101a, as Figure 8E shown.

[0100] In one embodiment, in step S2 of cutting the flexible substrate 101 to form at least two strip structures 101a, at least one removal part is cut out in the display area of the flexible substrate 101 by laser cutting, and then the removal part is removed by laser lift-off. A through hole is formed in the area corresponding to the removal part, and the other areas in the display area are separated into at least two strip structures 101a by the through holes.

[0101] In some embodiments of the present invention, in step S4 of interweaving the light-emitting fiber 201 with at least part of the strip structures 101a and electrically connecting the light-emitting fiber 201 to the transistor layer of the strip structure 101a, it further includes:
