Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the related art, a microcapsule temperature-controlled color-changing layer is disposed on an outer fabric layer of the clothes, the microcapsule temperature-controlled color-changing layer displays different colors at different external temperatures, and the whole color-changing process is reversible. Because the external temperature is not controlled by the user, the pattern displayed by the temperature control color changing layer is not controlled by the user; the display color is determined after the microcapsule is encapsulated, and the type of the displayed color is fixed. As another example, in the related art, there is provided a multifunctional color-changing garment, in which a zipper is provided, and when the zipper is unzipped, a hidden fluorescent cloth can be displayed without intelligence. Further illustratively, in the related art, there is provided an intelligent color-changing garment, by a method of providing a photothermal color-changing antibacterial layer outside a garment body, since colors of the photothermal color-changing antibacterial layer show different colors at different external temperatures and light, since the external temperatures and light are not controlled by a user, patterns shown by the temperature-controlled color-changing layer are also not controlled by the user.

In order to solve the above problem, an embodiment of the present invention provides a fiber tube 1, as shown in fig. 1A to 2B, including: a transparent fiber tube 12, a closed cavity 13 and electronic ink 14 filled in the closed cavity.

A plurality of closed chambers 13 are located inside the fiber tube body 12. The plurality of closed cavities 13 are distributed along the length direction of the fiber pipe body 12; electronic ink 14 filled in the closed cavity 13, wherein the electronic ink 14 includes: positive electrophoretic particles 141, negative electrophoretic particles 142, and a transparent filling liquid 143; wherein the colors of the positive electrophoretic particles 141 and the negative electrophoretic particles 142 are different.

Wherein, the number of the positive electrophoretic particles 141 and the negative electrophoretic particles 142 in each of the closed cavities 13 is plural. The shape of the sealed cavity 13 is not limited, and for example, as shown in fig. 1A and 1B, the sealed cavity 13 has a cylindrical shape, or as shown in fig. 2A and 2B, the sealed cavity 13 has a spherical shape.

On this basis, the migration directions of the positive electrophoretic particles 141 and the negative electrophoretic particles 142 in the transparent filling liquid 143 are controlled by the electric field, and since the fiber tube 12 is transparent, the positive electrophoretic particles 141 and the negative electrophoretic particles 142 are accumulated on the surface of the transparent fiber tube 12 in different amounts inside the fiber tube 12 to present different colors, so that the color presented by the fiber tube 1 can be controlled by applying different electric fields around the fiber tube 12, that is, the color displayed by the fiber tube 1 can be controlled and can include multiple colors, wherein the different electric fields mean that at least one of the directions and magnitudes of the electric fields are different.

Optionally, as shown in fig. 3, the fiber tube body 12 further includes: a plurality of inner chamber walls 15 are arranged at intervals along the length direction of the fiber tube 12, and each inner chamber wall 15 is connected to the inner surface 12a of the fiber tube 12 to form a plurality of closed chambers 13.

Alternatively, as shown in fig. 4A and 4B, the fiber tube 1 further includes: the fiber tube comprises at least two strip electrodes 16 arranged outside a fiber tube body, wherein the strip electrodes 16 extend along the length direction of the fiber tube 1, the at least two strip electrodes 16 are distributed at intervals along the circumferential direction of the fiber tube 1, and the at least two strip electrodes 16 are mutually insulated.

Wherein, in order to ensure that the electronic ink 14 in the fiber tube 1 can be used for displaying colors normally, the material of the strip-shaped electrodes 16 is transparent or semitransparent material. In addition, when the fiber tube body 12 in the fiber tube 1 is used for flexible display, the material of the fiber tube body 12 is flexible, and in this case, in order to ensure that the performance of the fiber tube body 12 is not affected when the strip-shaped electrode is manufactured on the outer surface of the fiber tube body 12, a low-temperature process is used for manufacturing the strip-shaped electrode. For example, aluminum-doped zinc oxide (AZO) may be used to fabricate the strip electrodes 16, the AZO may be fabricated at a low temperature (150-325 ℃) and the minimum bending radius may be up to 7 mm.

Illustratively, the number of the stripe electrodes 16 in fig. 4A is 2, and the number of the stripe electrodes 16 in fig. 4B is 4. The following examples of the present invention are all described with 4 strip electrodes 16.

Optionally, as shown in fig. 5, the fiber tube 1 further includes an insulating layer 17, the insulating layer 17 covers the at least two strip-shaped electrodes 16 and the first portion 121 of the fiber tube body 12, and the first portion 121 of the fiber tube body 12 is a portion of the fiber tube body 12 exposed between the at least two strip-shaped electrodes 16.

The insulating layer 17 is used to ensure the mutual insulation between the adjacent strip electrodes 16, and can protect the strip electrodes 16 from the surface of the fiber tube body 12 and the first portion 121 of the fiber tube body 12, and meanwhile, the insulating layer 17 is used to provide the supporting strength for the fiber tube 1. Illustratively, the material of the insulating layer 17 is a transparent resin.

On the other hand, as shown in fig. 6, the embodiment of the present invention provides a textile thread 2, including: at least two fibre tubes 1 twisted together, the fibre tubes 1 being fibre tubes 1 as described hereinbefore.

The kinking of the at least two fiber tubes 1 means that the at least two fiber tubes 1 are combined together in a mutually intertwined manner, or the at least two fiber tubes 1 are combined together by means of bonding with an adhesive.

Alternatively, in the textile thread 2, each fiber tube includes negative electrophoretic particles and positive electrophoretic particles, wherein one of the electrophoretic particles has a background color and the other electrophoretic particle has a primary color.

Different fiber tubes contain electrophoretic particles with different primary colors and the same electric property.

Different colors can be displayed on one side of the fiber tube 1 by combining two kinds of the positive-type electrophoretic particles 141 and the negative-type electrophoretic particles 142 of different colors in different amounts for the same fiber tube 1. When at least two fiber tubes 1 are twisted together, different colors of the fiber tubes 1 may be mixed together to display another color, in which case the kind of color displayed by the textile thread 2 can be increased.

Alternatively, in the textile thread 2, the background color is white, and in the case where the color of the negative electrophoretic particles 142 in different fiber tubes is the same, the negative electrophoretic particles 142 are white.

In the case where the colors of the positive electrophoretic particles 141 in different fiber tubes are the same, the positive electrophoretic particles 141 are white.

For example, the negative electrophoretic particles in different fiber tubes have the same color, which is the background color; and the colors of the positive electrophoretic particles in different fiber tubes are different and are respectively different primary colors. Taking an example that one textile thread comprises 3 fiber tubes, the negative electrophoretic particles of the 3 fiber tubes are all white, and the colors of the positive electrophoretic particles in the 3 fiber tubes are red, green and blue respectively. On one side of the same fiber tube 1, the white electrophoretic particles and the primary electrophoretic particles are matched in different quantities to display different gray scales of the same primary color. For example, when the textile thread 2 is formed by twisting 3 fibers 1, for the first fiber tube 1, in the case where the negative electrophoretic particles 142 are white and the positive electrophoretic particles 141 are red, red with different gray scales (i.e., different brightness) may be displayed on one side of the fiber tube 1; for the second fiber tube 1, when the negative electrophoretic particles 142 are white and the positive electrophoretic particles 141 are green, green with different gray scales (i.e. different brightness) can be displayed on one side of the fiber tube 1; for the third fiber tube 1, when the negative electrophoretic particles 142 are white and the positive electrophoretic particles 141 are blue, blue with different gray scales (i.e., different brightness) can be displayed on one side of the fiber tube 1. The red of different gray levels, the green of different gray levels and the blue of different gray levels can be combined to form a plurality of colors.

In a further aspect, the present invention provides a textile fabric 3, which is woven by textile threads 2, wherein the textile threads 2 are textile threads as described above.

The textile 3 provided by the embodiment of the invention is woven by the textile threads 2, and the textile 3 can display various colors because the textile threads 2 can display different colors. Further, the textile 3 may be used to display different patterns.

In another aspect, as shown in fig. 7, an embodiment of the invention provides a display device. The method comprises the following steps: the textile 3, the pixel circuit layer 4, the common electrode layer 5 and the drive circuitry 6 as described hereinbefore.

As shown in fig. 8, the pixel circuit layer 4 includes a plurality of gate lines 43 and a plurality of data lines 44, switching devices connected to the plurality of gate lines 43 and the plurality of data lines 44, and a plurality of pixel electrodes 41. Wherein the plurality of gate lines 43 and the plurality of data lines 44 are disposed to cross, e.g., perpendicular to each other. The switching device may be, for example, a Thin Film Transistor (TFT).

The common electrode layer 5 is located on the side of the textile 3 remote from the pixel circuit layer 4. The common electrode layer 5 and the plurality of pixel electrodes 41 are disposed to face each other.

The driving circuit comprises a grid driving circuit and a source driving circuit, and all grid lines are connected with the grid driving circuit. All the data lines are connected with the source electrode driving circuit.

The driving circuit also comprises a strip electrode driving circuit, and strip electrodes on all the fiber tubes are connected with the strip electrode driving circuit.

In some embodiments, the display device may further include a first substrate on which the pixel circuit layer may be disposed; illustratively, the first substrate may be a flexible substrate. The display device may further include a second substrate, and the common electrode layer may be disposed on the second substrate; illustratively, the second substrate may be a flexible substrate.

On this basis the textile 3 is used for displaying the pattern and the drive circuit is used for controlling the textile 3, the pixel circuit layer 4 and the common electrode layer 5 for controlling the textile 3. The operation of the display device is described as follows.

The textile thread 2 comprises three fiber tubes 1, the negative electrophoresis particles 141 in the three fiber tubes 1 are in the same color, the negative electrophoresis particles 141 in the three fiber tubes 1 are all white, the positive electrophoresis particles 142 in the three fiber tubes 1 are in different colors, for example, the electrophoresis particles in the three fiber tubes 1 are in the first color, the second color and the third color respectively. The first color may be the three primary colors for display, e.g., red R, green G, and blue B.

The plurality of gate lines 43 and the plurality of data lines 44 intersect to define a plurality of pixels, so that the plurality of pixel electrodes 41 in the array substrate 4 are arranged in an array, and the pixel electrodes 41 are electrically connected to the first electrodes of the TFTs. The grid electrodes of the TFTs in the same row of pixels are electrically connected with the grid lines, and the second poles of the TFTs gathered in Jiangsu in the same column are electrically connected with the data lines. The color of each pixel is determined by the first, second and third colors and their gray scale.

Since the textile thread 2 is formed by kinking the fiber tubes 1 of the first color R, the fiber tubes 1 of the second color G and the fiber tubes 1 of the third color B, the fiber tubes 1 of the first color R, the fiber tubes 1 of the second color G and the fiber tubes 1 of the third color B are interlaced together, and thus the gray levels of the first color, the second color and the third color in each pixel cannot be controlled separately by the driving circuit. However, the gray scales of the first color, the second color, and the third color in each pixel can be controlled together by the driving circuit, and at this time, the color of each pixel can be controlled by the driving circuit, so that the screen displayed by the display device can be controlled.

Alternatively, as shown in fig. 9, when the fiber tube 1 further includes the strip electrode 16, the driving circuit 42 further includes a strip electrode driving circuit 421. At this time, the strip electrodes 16 and the strip electrode driving circuit 421 are electrically connected by using a Chip On Film (COF) technology.

Specifically, as shown in fig. 10, the insulating layer outside the strip-shaped electrodes 16 is removed to expose portions of the strip-shaped electrodes 16, the portions of the strip-shaped electrodes 16 exposed are directly connected to an Anisotropic Conductive Film (ACF) 18, the ACF18 is electrically connected to a Conductive wire in a Flexible Printed Circuit (FPC) 19 by hot pressing, and the ACF18 is electrically connected to the strip-shaped electrode driving Circuit 421, that is, the strip-shaped electrodes 16 and the strip-shaped electrode driving Circuit 421 are electrically connected to the FPC19 through the ACF 18. The strip electrode driving Circuit 421 is an Integrated Circuit (IC), and the IC is directly disposed on the FPC.

Here, since the width between the conductive wires 191 in the FPC18 is much smaller than the width between the adjacent strip-shaped electrodes 16 in the fiber tube 1, the adjacent strip-shaped electrodes 16 are not electrically connected through the conductive wires in the FPC 18. Illustratively, the width of the conductive wires 191 is 0.03mm, the spacing between adjacent conductive wires 191 is 0.02mm, and the spacing between adjacent strip-shaped electrodes 16 is 0.3 mm.

On the basis, the gray scales of the first color, the second color and the third color in each pixel are controlled by the driving circuit, so that the colors of the pixels formed by the first color, the second color and the third color are more, and the display device can be used for displaying pictures with richer colors.

As an example, when the fiber tube 1 includes a strip electrode, the operation principle of the display device is described as follows.

First of all. As shown in fig. 10 and 11, the fiber tube 1 includes strip electrodes 16. When the strip electrodes 16 are insulated from each other, each strip electrode 16 can be equivalent to an isolated plate. At this time, an electric field E is applied to both sides of the fiber tube 1, and the electric charge distribution on the strip-shaped electrodes 16 is as shown in fig. 11, and the electric field E may act on the positive electrophoretic particles 141 and the negative electrophoretic particles 142 in the fiber tube 1 to control the migration of the positive electrophoretic particles 141 and the negative electrophoretic particles, so as to control the number of the positive electrophoretic particles 141 and the negative electrophoretic particles 142 accumulated on the surface of the transparent fiber tube 12, thereby controlling the color of the fiber tube.

As shown in fig. 10 and 12, the fiber tube 1 includes strip electrodes 16. When the strip electrodes 16 provided on the same fiber tube 1 are conducted to each other using the strip electrode 16 driving circuit, the combination of all the strip electrodes 16 can be made equivalent to one conductor. At this time, an electric field E is applied to both sides of the fiber tube 1, and since all the strip electrodes are combined into one conductor, and the electric charges on the strip electrodes 16 form a new electric field E ' by using the electrostatic shielding principle, the electric field E ' is equal to the electric field E in magnitude and opposite in direction, so that the electric field E ' and the electric field E can cancel each other, the electric field inside the fiber tube 1 is 0, and the electric field E does not act on the positive electrophoretic particles 141 and the negative electrophoretic particles 142 inside the fiber tube 1.

On the basis, the gate driving circuit controls the TFTs corresponding to all pixels of the row to be opened by inputting a gate driving signal to one gate line, at the moment, the source driving circuit respectively inputs first color data signals to a plurality of data lines, the strip-shaped electrode driving circuit conducts strip-shaped electrodes on the fiber tubes corresponding to the positive electrophoretic particles of the second color to each other, the strip-shaped electrodes on the fiber tubes corresponding to the positive electrophoretic particles of the third color to each other, the first color data signals can be input to the pixel electrodes, and the electrophoresis of the positive electrophoretic particles and the negative electrophoretic particles in the fiber tubes including the positive electrophoretic particles of the first color is controlled, so that the gray scale of the first color is controlled.

Since the electronic ink has a bistable effect, even if the electric field for controlling the migration of the positive electrophoretic particles and the negative electrophoretic particles is removed, the last displayed picture can be maintained, and in the case where the gray scale of the first color is not changed, the driving circuit can sequentially and independently control the gray scale of the second color and the gray scale of the third color with reference to the above principle.

Therefore, when the fiber tube further comprises the strip-shaped electrodes, the gray scale of the first color, the gray scale of the second color and the gray scale of the third color corresponding to each pixel can be independently controlled through the driving circuit, so that a more colorful picture can be displayed.

In another aspect, an embodiment of the present invention provides an intelligent wearable device, which includes the textile fabric, and a user may adjust a picture displayed by the textile fabric according to a requirement.

In another aspect, an embodiment of the present invention provides a driving method of a display device, including the display device. In the case that, in at least one textile line of a display device, each fiber tube contains negative electrophoretic particles and positive electrophoretic particles, wherein the color of one electrophoretic particle is a background color, the color of the other electrophoretic particle is a primary color, different fiber tubes contain electrophoretic particles with different primary colors and the same electrical property, and each fiber tube contained in at least one textile line contains a strip electrode, the driving method of the display device comprises the following steps:
