[0067] Through the above-mentioned drawings, specific embodiments of the present application have been shown, and more detailed descriptions will be given later. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed Embodiments

[0068] To make the objectives, technical solutions, and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0069] A reflective display device is a device structure that uses natural light for display. Clear display can be achieved using ambient light under strong or weak light conditions, and it has the advantages of low driving voltage, energy saving, and little damage to the eyes. Current reflective display devices include various structures. For example, there are Electronic-Ink (E-Ink) reflective display devices and Clear-Ink (CID) reflective display devices.

[0070] For the structure of an E-Ink reflective display device, please refer to Figure 1 , Figure 1FIG. 0 is a schematic structural diagram of a reflective display device provided by the related art. The reflective display device A includes: a first substrate A1, a second substrate A2, a first electrode layer A3, a second electrode layer A4, microcapsules A5, black particles A6, white particles A7, and ink A8. Among them, a plurality of microcapsules A5 are located between the first electrode layer A3 and the second electrode layer A4. The black particles A6, white particles A7, and ink A8 are all disposed in the sealed microcapsules A5. The black particles A6 carry negative charges, and the white particles A7 carry positive charges. When no external voltage is applied, the microcapsules A5 as a whole exhibit an electro-equilibrium state. When a positive voltage is applied to the first electrode layer A3, the black particles A6 approach the first electrode layer A3, and the white particles A7 are distributed in the region of the microcapsules A5 close to the second electrode layer A4. Ambient light incident from the side of the second substrate A2 away from the second electrode layer A4 is reflected at the white particles A7, and then the reflective display device A presents a bright state. When a negative voltage is applied to the first electrode layer A3, the white particles A7 approach the first electrode layer A3, and the black particles A6 are distributed in the region of the microcapsules A5 close to the second electrode layer A4. Ambient light incident from the side of the second substrate A2 away from the second electrode layer A4 is absorbed at the black particles A6, and then the reflective display device A presents a dark state.

[0071] Please refer to the CID reflective display device Figure 2 and Figure 3 , Figure 2 FIG. 9 is a top view structural diagram of another reflective display device provided by the related art (to clearly show the structure of the pixel wall, Figure 2 the color filter substrate B2 is not shown), Figure 3 and Figure 2 FIG. 15 is a cross-sectional schematic diagram of the reflective display device shown in FIG. 14 at C1-C1. The reflective display device B includes: an array substrate B1, a color filter substrate B2, a pixel wall B3, a solvent B4, particles B5, a lens structure B6, and a rubber frame B7. The pixel wall B3 and the array substrate B1 and the color filter substrate B2 form a closed structure, and each pixel corresponds to a closed structure formed by a pixel wall B3. The reflective display device B can be a single-particle display or a dual-particle display. The single-particle display is to stably disperse colored and charged particles B5 in a colored solvent B4. Under the action of an external electric field, the particles B5 realize the display of images and texts through electrophoretic migration movement in the ink B4. The dual-particle display is to stably disperse two different colors of particles B5 with opposite charges in a colorless solvent B4. Under the action of an external electric field, the particles B5 realize the display of images and texts through migration movement toward opposite-polarity electrodes.

[0072] The particles dispersed in the solvent are the core components of the reflective display device and will directly affect the display effect of the reflective display device. Please refer to Figure 4 , Figure 4It is a schematic structural diagram of another reflective display device provided by the related art. The reflective display device D includes: a first substrate D1, a second substrate D2, a pixel wall D3, a solvent D4, particles D5, and a rubber frame D6. The pixel wall D3 and the first substrate D1 and the second substrate D2 form a plurality of sealed chambers, and a plurality of pixels respectively correspond to the plurality of chambers.

[0073] However, as shown in the area D7, manufacturing errors in the pixel wall D3 in different areas cause gaps between the pixel wall D3 and the second substrate D2, or the first substrate D1 and the second substrate D2 are not completely sealed during the cell alignment setting, both of which will result in poor sealing of some chambers, and thus the particles D5 are likely to move between pixels. On the one hand, the particles D5 that move to other pixels will cause the voltage applied by the first substrate D1 and the second substrate D2 to not accurately control the movement of the particles D5, resulting in the actual gray level finally displayed not being able to reach the target gray level. On the other hand, since the particles D5 in some chambers are lost, the black-and-white states corresponding to these chambers will be interfered, resulting in poor contrast. Therefore, the display effect of the reflective display device provided by the related art is poor.

[0074] An embodiment of the present application provides a display panel. Please refer to Figure 5 , Figure 5 It is a schematic structural diagram of a display panel provided by an embodiment of the present application. The display panel 00 includes: a first substrate 10, a second substrate 20, a pixel wall 30, an electrophoretic layer 40, a first bonding reaction part 50, and a second bonding reaction part 60.

[0075] The first substrate 10 and the second substrate 20 are disposed opposite to each other. The first substrate 10 has a first electrode layer 11 on the side facing the second substrate 20, and the second substrate 20 has a second electrode layer 21 on the side facing the first substrate 10. Exemplarily, the first substrate 10 can be an upper substrate, and the second substrate 20 can be a lower substrate. The first electrode layer 11 can be a thin film transistor array, and each pixel corresponds to at least one thin film transistor to achieve individual control of each pixel. The second electrode layer 21 can be a common electrode with a whole-layer structure. The first electrode layer 11 and the second electrode layer 21 cooperate to form an electric field between the first substrate 10 and the second substrate 20, and the direction of the electric field is controllable, so as to be used to drive the movement of the particles 41. The strength and frequency of this electric field have a certain impact on the response speed of the display panel 00. Exemplarily, the materials of the first electrode layer 11 and the second electrode layer 21 can include indium tin oxide (ITO). ITO is a transparent conductive oxide, which can increase the transmittance of the reflected light.

[0076] It should be noted that the first substrate 10 further includes a first substrate 12, and the first substrate 12 can be used to carry the first electrode layer 11. The second substrate 20 further includes a second substrate 22, and the second substrate 22 can be used to carry the second electrode layer 21. The first substrate 12 and the second substrate 22 can be flexible substrates or rigid substrates, and the embodiments of the present application do not limit this. Exemplarily, the first substrate 12 and the second substrate 22 can both be glass substrates.

[0077] The pixel wall 30 is connected to the side of the first substrate 10 facing the second substrate 20, and the pixel wall 30 is used to enclose a plurality of separated chambers Q1. Here, the plurality of chambers Q1 respectively correspond to a plurality of pixels one by one, and the plurality of separated chambers Q1 are independent of each other, so that each pixel can be controlled separately. Therefore, it is crucial to ensure the independence and sealing of each chamber.

[0078] The electrophoretic layer 40 is distributed in the plurality of chambers Q1, and the electrophoretic layer 40 has a plurality of particles 41. Here, the plurality of particles 41 are charged, so that they can move in the chamber Q1 under the drive of an electric field. When the plurality of particles 41 move to different positions, different effects on ambient light can be achieved, such as a bright state or a dark state. The size, aggregation state, density, dielectric constant, optical properties (such as color and refractive index, etc.) and surface charge state of the particles 41 all have an important impact on the display effect of the display panel 00.

[0079] In the present application, the plurality of particles 41 can include at least one of black particles and white particles. Exemplarily, as Figure 5 shown, the plurality of particles 41 distributed in each chamber Q1 can include a plurality of black particles and a plurality of white particles.

[0080] It should be noted that the electrophoretic layer 40 further includes a solvent 42, and the solvent 42 can be used as a medium for the movement of the particles 41. The viscosity, physical properties, optical properties (such as transparency and refractive index, etc.), chemical properties and dielectric properties of the solvent 42 all have a certain impact on the display effect of the display panel 00.

[0081] The first bonding reaction part 50 is distributed between the pixel wall 30 and the second substrate 20, and the first bonding reaction part 50 is connected to at least one of the pixel wall 30 and the second substrate 20. This includes the following three situations:

[0082] (1) The first bonding reaction part 50 is only connected to the pixel wall 30, that is, the first bonding reaction part 50 is coated on the pixel wall 30.

[0083] (2) The first bonding reaction part 50 is only connected to the second substrate 20, that is, the first bonding reaction part 50 is coated on the second substrate 20.

[0084] (3) The first adhesive reaction part 50 is connected to both the pixel wall 30 and the second substrate 20, that is, the first adhesive reaction part 50 is coated on the pixel wall 30 and the second substrate 20.

[0085] The second adhesive reaction part 60 is distributed between the first substrate 10 and the second substrate 20. Here, the materials of the second adhesive reaction part 60 and the first adhesive reaction part 50 are materials capable of undergoing a polymerization reaction. Exemplarily, the materials of the second adhesive reaction part 60 and the first adhesive reaction part 50 can be acrylate glue.

[0086] Among them, the first adhesive reaction part 50 is used to undergo a polymerization reaction and form a sealing adhesive part M after contacting the second adhesive reaction part 60, so that the second substrate 20 can be adhered to the pixel wall 30 through the sealing adhesive part M. Here, during the polymerization reaction between the first adhesive reaction part 50 and the second adhesive reaction part 60, strong chemical bonds can be formed, so that the formed sealing adhesive part M has high adhesive strength and density, and further, the chamber Q1 can achieve good sealing performance, effectively avoiding the problem of crosstalk caused by the movement of particles 41 between pixels.

[0087] It should be noted that the sealing adhesive part M is the substance generated after the polymerization reaction between the first adhesive reaction part 50 and the second adhesive reaction part 60. Figure 5 The shown sealing adhesive part M is to indicate the area where the sealing adhesive part M is located, not the specific structure of the sealing adhesive part M. When the first adhesive reaction part 50 and the second adhesive reaction part 60 have not fully reacted, there are still unreacted parts of the first adhesive reaction part 50 and the second adhesive reaction part 60 in the area where the sealing adhesive part M is located.

[0088] In summary, the embodiment of the present application provides a display panel, in which a first adhesive reaction part is provided between the pixel wall and the second substrate, and a second adhesive reaction part is provided between the first substrate and the second substrate. Since the first adhesive reaction part can undergo a polymerization reaction and form a sealing adhesive part after contacting the second adhesive reaction part, the sealing adhesive part can adhere the second substrate and the pixel wall to ensure good sealing performance of the chamber, thereby avoiding particles migrating to adjacent chambers, reducing the risk of particle loss, and further improving the display effect of the display panel.

[0089] Optionally, the material of the first adhesive reaction part 50 includes: vinyl ester and active radical catalyst. Among them, vinyl ester can be used as a resin matrix to provide the main adhesive force and physical properties of the sealing adhesive part M. Vinyl ester resins usually have good weather resistance, corrosion resistance and mechanical properties. The active radical catalyst can be used to initiate the reaction and accelerate the copolymerization process between vinyl ester and vinyl monomer.

[0090] The materials of the second bonding reaction part 60 include: vinyl monomers and active radical promoters. Among them, the vinyl monomers can be used as comonomers to participate in the polymerization reaction with vinyl ester resins to form polymer chains. The types and proportions of vinyl monomers have important effects on the properties of adhesives such as viscosity, hardness, and weather resistance. The synergistic effect of the active radical promoter and the catalyst can accelerate the progress of the polymerization reaction. By adjusting the types and dosages of the active radical promoters, the rate of the polymerization reaction and the properties of the sealed bonding part M, such as curing speed and viscosity change, can be further controlled.

[0091] Therefore, in the first bonding reaction part 50 and the second bonding reaction part 60, vinyl ester and vinyl monomers are the main components for forming the sealed bonding part M, while the active radical catalyst and the active radical promoter act as initiators of the reaction, accelerating the progress of the polymerization reaction.

[0092] The embodiments of the present application can also improve the speed of the polymerization reaction by setting the reaction temperature. The higher the temperature, the more intense the molecular movement, the faster the chemical reaction speed, and the shorter the curing time. However, too high a temperature may lead to a decrease in bonding strength. Exemplarily, the polymerization reaction occurring in the first bonding reaction part 50 and the second bonding reaction part 60 can be carried out at 50 degrees Celsius, so as to accelerate the reaction speed on the basis of ensuring the reliability of the display panel 00 without affecting the bonding strength.

[0093] In the embodiments of the present application, there are various situations for the distribution positions of the second bonding reaction part. The following will be described with two exemplary embodiments:

[0094] In the first exemplary embodiment, please refer to Figure 5 , the second bonding reaction part 60 is distributed between the pixel wall 30 and the second substrate 20. In this way, by setting the thicknesses of the first bonding reaction part 50 and the second bonding reaction part 60, it is convenient to make the first bonding reaction part 50 and the second bonding reaction part 60 contact, so that the polymerization reaction can occur to achieve bonding.

[0095] Among them, the first bonding reaction part 50 is connected to one of the pixel wall 30 and the second substrate 20, and the second bonding reaction part 60 is connected to the other of the pixel wall 30 and the second substrate 20. That is, the first bonding reaction part 50 is connected to the pixel wall 30, and the second bonding reaction part 60 is connected to the second substrate 20. Or, the first bonding reaction part 50 can also be connected to the second substrate 20, and the second bonding reaction part 60 is connected to the pixel wall 30.

[0096] Optionally, taking Figure 5 as an example, the first bonding reaction part 50 is coated on the side of the pixel wall 30 facing the second substrate 20, and the second bonding reaction part 60 is coated on the side of the second substrate 20 facing the first substrate 10.

[0097] Among them, the sealed bonding part M is located between the unreacted part of the first bonding reaction part 50 and the unreacted part of the second bonding reaction part 60. Here, when the first substrate 10 and the second substrate 20 are set in a cell, the first bonding reaction part 50 and the second bonding reaction part 60 can be in direct contact and start to undergo a polymerization reaction.

[0098] During the polymerization reaction, the substance generated by the reacted parts of the first bonding reaction part 50 and the second bonding reaction part 60 is the sealed bonding part M, and the sealed bonding part M is located between the unreacted parts of the two. After the first bonding reaction part 50 and the second bonding reaction part 60 completely react, one side of the sealed bonding part M is bonded to the pixel wall 30, and the other side is bonded to the second substrate 20, which can achieve better bonding strength and the chamber Q1 has better sealing performance.

[0099] In the second exemplary embodiment, please refer to Figure 6 , Figure 6 which is a schematic structural diagram of another display panel provided by an embodiment of the present application. The electrophoresis layer 40 further includes: a solvent 42, and a plurality of particles 41 are dispersed in the solvent 42. The second bonding reaction part 60 is an organic material mixed in the solvent 42. That is to say, the solvent 42 can also be used as a dispersion medium for the second bonding reaction part 60. The solvent 42 can have characteristics such as good chemical stability, low viscosity and dielectric constant, and chemical inertness to ensure that the second bonding reaction part 60 does not react with the solvent 42.

[0100] Among them, after the first bonding reaction part 50 contacts the solvent 42, it undergoes a polymerization reaction through the second bonding reaction part 60 in the solvent 42 and forms the sealed bonding part M. Here, the second bonding reaction part 60 can swim in the solvent 42. When the first substrate 10 and the second substrate 20 are set in a cell, the first bonding reaction part 50 coated on the pixel wall 30 and / or coated on the second substrate 20 can contact the solvent 42.

[0101] Exemplarily, the materials of the second bonding reaction part 60 and the first bonding reaction part 50 can include organic materials with the same polarity. Because there is a strong dipole-dipole interaction between polar molecules, it will make the second bonding reaction part 60 easier to move to the position where the first bonding reaction part 50 is set and contact the first bonding reaction part 50 to undergo a polymerization reaction.

[0102] For the second exemplary embodiment, the setting positions of the first bonding reaction part 50 include the following three cases:

[0103] For the first case, please refer to Figure 6, the first bonding reaction part 50 includes: separated first sub-reaction layer 51 and second sub-reaction layer 52. The first sub-reaction layer 51 is coated on the side of the pixel wall 30 facing the second substrate 20, and the second sub-reaction layer 52 is coated on the side of the second substrate 20 facing the first substrate 10. That is, before the first substrate 10 and the second substrate 20 are set in a cell, the first bonding reaction part 50 is coated on both the pixel wall 30 and the second substrate 20.

[0104] Among them, after the first sub-reaction layer 51 and the second sub-reaction layer 52 come into contact with the solvent 42, they both undergo a polymerization reaction through the second bonding reaction part 60 in the solvent 42, and a sealing bonding part M is formed between the unreacted parts of the first sub-reaction layer 51 and the second sub-reaction layer 52. Here, the second bonding reaction part 60 can swim in the solvent 42. When the first substrate 10 and the second substrate 20 are set in a cell, both the first sub-reaction layer 51 and the second sub-reaction layer 52 can come into contact with the solvent 42. When the second bonding reaction part 60 swims between the first sub-reaction layer 51 and the second sub-reaction layer 52, it can come into contact with both the first sub-reaction layer 51 and the second sub-reaction layer 52 to undergo a polymerization reaction, thereby improving the bonding strength.

[0105] During the polymerization reaction, the substances generated by the reacted parts of the first sub-reaction layer 51, the second sub-reaction layer 52, and the second bonding reaction part 60 are the sealing bonding part M, and the sealing bonding part M is located between the unreacted parts of the first sub-reaction layer 51 and the second sub-reaction layer 52. After the first bonding reaction part 50 and the second bonding reaction part 60 completely react, one side of the sealing bonding part M is bonded to the pixel wall 30, and the other side is bonded to the second substrate 20, which can achieve better bonding strength and the chamber Q1 has better sealing performance.

[0106] For the second case, please refer to Figure 7 , Figure 7 is a schematic structural diagram of another display panel provided by an embodiment of the present application. The first bonding reaction part 50 is coated on the side of the second substrate 20 facing the first substrate 10.

[0107] Among them, after the first bonding reaction part 50 comes into contact with the solvent 42, it undergoes a polymerization reaction through the second bonding reaction part 60 in the solvent 42, and a sealing bonding part M is formed between the unreacted part of the first bonding reaction part 50 and the pixel wall 30.

[0108] Before the first substrate 10 and the second substrate 20 are set in a cell, a first adhesive reaction part 50 is coated on the second substrate 20. When the first substrate 10 and the second substrate 20 are set in a cell, the first adhesive reaction part 50 can contact with the solvent 42. Since the second adhesive reaction part 60 is dispersed in the solvent 42, when the second adhesive reaction part 60 swims between the first adhesive reaction part 50 and the pixel wall 30, it can contact with the first adhesive reaction part 50 to cause a polymerization reaction.

[0109] During the polymerization reaction, the substance generated by the reacted parts of the first adhesive reaction part 50 and the second adhesive reaction part 60 is the sealing adhesive part M, and the sealing adhesive part M is located between the unreacted part of the first adhesive reaction part 50 and the pixel wall 30. After the first adhesive reaction part 50 and the second adhesive reaction part 60 completely react, one side of the sealing adhesive part M is adhered to the pixel wall 30, and the other side is adhered to the second substrate 20, which can achieve better adhesive strength and the sealing performance of the chamber Q1 is better.

[0110] For Figure 7 the shown display panel 00, when the first substrate 10 and the second substrate 20 are set in a cell, the solvent 42 will be squeezed. Since it takes a certain time for the polymerization reaction to occur, there may be a gap between the pixel wall 30 away from the first substrate 10 and the second substrate 20. The squeezed solvent 42 may be distributed at this gap, and the particles 41 in the squeezed solvent 42 may remain on the side of the pixel wall 30 away from the first substrate 10, thus also causing the loss of particles.

[0111] Therefore, please refer to Figure 8 , Figure 8 which is a schematic structural diagram of another display panel provided by an embodiment of the present application. A liquid-repellent layer 70 is also provided in the display panel 00, and the liquid-repellent layer 70 is located on the side of the pixel wall 30 away from the first substrate 10. Based on the liquid-repellent property of the liquid-repellent layer 70, the surface of the liquid-repellent layer 70 is not easily wetted by liquid, and the liquid-repellent layer 70 has a low surface energy and lacks attraction to liquid. That is, the solvent 42 is not easily distributed on the side of the pixel wall 30 away from the first substrate 10, so that the risk of the particles 41 remaining on the side of the pixel wall 30 away from the first substrate 10 can be reduced, and further the problem of particle loss can be reduced and the display effect can be improved. Exemplarily, the material of the liquid-repellent layer 70 may include Teflon, but the present application is not limited thereto.

[0112] For the third case, please refer to Figure 9 , Figure 9 which is a schematic structural diagram of another display panel provided by an embodiment of the present application. The first adhesive reaction part 50 is coated on the side of the pixel wall 30 facing the second substrate 20.

[0113] Among them, after the first adhesive reaction part 50 comes into contact with the solvent 42, a polymerization reaction occurs through the second adhesive reaction part 60 in the solvent 42, and a sealing adhesive part M is formed between the unreacted part of the first adhesive reaction part 50 and the second substrate 20.

[0114] Before the first substrate 10 and the second substrate 20 are set in a pair, the first adhesive reaction part 50 is coated on the side of the pixel wall 30 facing the second substrate 20. When the first substrate 10 and the second substrate 20 are set in a pair, the first adhesive reaction part 50 can come into contact with the solvent 42. Since the second adhesive reaction part 60 is dispersed in the solvent 42, when the second adhesive reaction part 60 swims between the first adhesive reaction part 50 and the second substrate 20, it can come into contact with the first adhesive reaction part 50 to cause a polymerization reaction.

[0115] During the polymerization reaction, the substance generated by the reacted parts of the first adhesive reaction part 50 and the second adhesive reaction part 60 is the sealing adhesive part M, and the sealing adhesive part M is located between the unreacted part of the first adhesive reaction part 50 and the second substrate 20. After the first adhesive reaction part 50 and the second adhesive reaction part 60 completely react, one side of the sealing adhesive part M is adhered to the pixel wall 30, and the other side is adhered to the second substrate 20, which can achieve better adhesive strength and the sealing performance of the chamber Q1 is better.

[0116] Optionally, as Figure 5 shown, the sealing adhesive part M has a plurality of grid holes K1, the plurality of grid holes K1 correspond to the plurality of chambers Q1, and the orthographic projection of the grid holes K1 on the first substrate 10 overlaps with the orthographic projection of the corresponding chamber Q1 on the first substrate 10. Thus, the top view structure of the sealing adhesive part M is similar to the top view structure of the pixel wall 30. As Figure 2 shown, the top view structure of the sealing adhesive part M can also be a grid-like structure. In this way, taking black and white dual particles as an example, when the display panel 00 is in the dark state, it can prevent the sealing adhesive part M from affecting the absorption of incident ambient light by black particles, and when the display panel is in the bright state, it can also prevent the sealing adhesive part M from affecting the reflection of incident ambient light by white particles, thereby improving the display effect.

[0117] Optionally, the highest part of the pixel wall 30 is the first wall 31, and the lowest part of the pixel wall 30 is the second wall 32. Here, due to manufacturing process errors, there may be a height difference on the side of the pixel wall 30 facing away from the first substrate 10, which is also one of the reasons for the poor sealing performance of the chamber Q1.

[0118] The part of the sealing adhesive part M located between the first wall 31 and the second substrate 20 is the first sealing part M1, and the part of the sealing adhesive part M located between the second wall 32 and the second substrate 20 is the second sealing part M2.

[0119] Among them, in the direction perpendicular to the first substrate 10, the thickness H1 of the first sealing portion M1 is smaller than the thickness H2 of the second sealing portion M2. That is to say, in this application, by setting the thickness of the sealing adhesive portion M, the height difference on the side of the pixel wall 30 away from the first substrate 10 can be compensated, the bonding strength and the sealing performance can be improved, thereby particle loss can be avoided and the display effect can be enhanced. Exemplarily, for the portion with a lower height in the pixel wall 30, a relatively large amount of the first bonding reaction portion 50 and / or the second bonding reaction portion 60 can be coated in the corresponding area.

[0120] In an exemplary embodiment, please refer to Figure 10 , Figure 10 which is a schematic structural diagram of another display panel provided by an embodiment of this application. The first substrate 10 includes: a first substrate 12, a reflective layer 13, a first passivation layer 14, a first electrode layer 11, and a first passivation layer 15 that are stacked. Among them, the reflective layer 13 can be used to reflect ambient light and can improve the reflection intensity of ambient light. Exemplarily, the material of the reflective layer 13 can be a metal material with a relatively high reflectivity, such as silver. The first passivation layer 14 can play a passivation and protection role, and the first passivation layer 14 can play an insulating role between the first electrode layer 11 and the reflective layer 13. The first passivation layer 15 covers the side of the first electrode layer 11 away from the first substrate 12 and can play an insulating and protecting role for the first electrode layer 11 to prevent the solvent 42 from corroding the first electrode layer 11. The first electrode layer 11 can include: a plurality of strip electrodes (slit ITO), and the plurality of strip electrodes correspond to a plurality of chambers Q1 to realize individual control of the particles 41 in each chamber Q1.

[0121] The second substrate 20 includes: a cover layer 24, a black matrix layer 25, a third passivation layer 23, a second electrode layer 21, and a second substrate 22 that are stacked. Among them, the third passivation layer 23 can play an insulating and protecting role for the second electrode layer 21 to prevent the conductive carbon particles that may exist in the black matrix layer 25 from affecting the voltage applied to the second electrode layer 21. The black matrix layer 25 can be used to prevent light crosstalk between adjacent pixels. The black matrix layer 25 can be a grid-like structure with a plurality of second grid holes K2, and the second grid holes K2 can allow the reflected light to pass through, so that the display function can be prevented from being affected. The cover layer 24 is disposed on the side of the black matrix layer 25 away from the second substrate 22, which can play a protecting role for the black matrix layer 25 and can also improve the flatness of the second substrate 20.

[0122] In this application, when the first bonding reaction portion 50 or the second bonding reaction portion 60 is coated on the second substrate 20, there are two situations, and here the first bonding reaction portion 50 is taken as an example to illustrate these two situations:

[0123] One situation is asFigure 10 As shown in Figure 10 , the first adhesive reaction part 50 is coated on the side of the black matrix layer 25 facing away from the second substrate 22 and is in contact with the black matrix layer 25. In this way, when forming the sealing adhesive part M, the overall thickness of the display panel 00 can be reduced.

[0124] Another case is as Figure 11 shown in Figure 11 Figure 11 is a schematic structural diagram of another display panel provided by an embodiment of the present application. The first adhesive reaction part 50 is coated on the side of the cover layer 24 facing away from the second substrate 22 and is in contact with the cover layer 24. The second case can be applied to Figure 9 the structure of the display panel shown in Figure 9 . In this way, it is convenient for the second adhesive reaction part 60 to swim between the second substrate 20 and the first adhesive reaction part 50, ensuring that the first adhesive reaction part 50 and the second adhesive reaction part 60 can contact to undergo a polymerization reaction. It should be noted that the second case can also be applied to the above other embodiments, and the embodiments of the present application will not elaborate here.

[0125] In summary, the embodiments of the present application provide a display panel. Among them, a first adhesive reaction part is provided between the pixel wall and the second substrate, and a second adhesive reaction part is provided between the first substrate and the second substrate. Since the first adhesive reaction part can undergo a polymerization reaction and form a sealing adhesive part after contacting the second adhesive reaction part, the sealing adhesive part can bond the second substrate and the pixel wall to ensure good sealing of the chamber, thereby avoiding particle migration to adjacent chambers, reducing the risk of particle loss, and further improving the display effect of the display panel.

[0126] Please refer to Figure 12 、 Figure 13 and Figure 14 , Figure 12 Figure 12 is a schematic manufacturing process diagram of another reflective display device provided by the related art, Figure 13 Figure 13 is Figure 12 a partial enlarged view of the reflective display device provided by Figure 12 in the E7 region, Figure 14 Figure 14 is Figure 13 a schematic top view structure diagram of the reflective display device provided by Figure 13 . The reflective display device E includes: a first substrate E1, a second substrate E2, an adhesive layer E3, a solvent E4, particles E5, and a pixel wall E6. In the reflective display device E, the first substrate E1 is a flexible substrate. In the related art, the first substrate E1 is rolled by a roller pressing method to rotate the roller downward, so that the pixel wall E6 is embedded in the adhesive layer E3, thereby realizing the enclosure. However, this manufacturing process will also cause the solvent E4 to be squeezed, so that the particles E5 dispersed in the solvent E4 remain on the side of the pixel wall E6 facing away from the first substrate E1, and further cause particle loss.

[0127] The present application provides a display panel. Please refer toFigure 15 , Figure 15 It is a schematic structural diagram of a display panel provided by an embodiment of the present application. The display panel includes: a first substrate 10, a second substrate 20, a pixel wall 30, an electrophoretic layer 40, and a liquid-repellent layer 70.

[0128] The first substrate 10 and the second substrate 20 are disposed opposite to each other. The first substrate 10 has a first electrode layer 11 on the side facing the second substrate 20, and the second substrate 20 has a second electrode layer 21 on the side facing the first substrate 10.

[0129] The pixel wall 30 is connected to the side of the first substrate 10 facing the second substrate 20, and the pixel wall 30 is used to enclose a plurality of separated chambers Q1.

[0130] The electrophoretic layer 40 is distributed in a plurality of chambers Q1. The electrophoretic layer 40 includes: a solvent 42, and a plurality of particles 41 distributed in the solvent 42.

[0131] The liquid-repellent layer 70 is located on the side of the pixel wall 30 facing away from the first substrate 10.

[0132] Due to the liquid-repellent property of the liquid-repellent layer 70, the surface of the liquid-repellent layer 70 is not easily wetted by the liquid, and the liquid-repellent layer 70 has a low surface energy and lacks attraction to the liquid. That is, the solvent 42 is not easily distributed on the side of the pixel wall 30 facing away from the first substrate 10, thereby reducing the risk of particles 41 remaining on the side of the pixel wall 30 facing away from the first substrate 10, further reducing the problem of particle loss, and improving the display effect. Exemplarily, the material of the liquid-repellent layer 70 may include Teflon, but the present application is not limited thereto.

[0133] It should be noted that the alignment method of the display panel provided by the embodiment of the present application is not limited to the above-mentioned roll pressing method. For the case where both the first substrate 10 and the second substrate 20 are rigid substrates, when other process methods are used for alignment, there will also be a certain extrusion of the solvent 42, resulting in the problem of particle 41 residue. Therefore, the present application provides a liquid-repellent layer 70 to improve the display effect of the display panel 00 in various manufacturing methods.

[0134] In summary, the embodiment of the present application provides a display panel, in which a liquid-repellent layer is provided on the side of the pixel wall facing away from the first substrate. Since the liquid-repellent layer has liquid-repellent properties and a low surface tension. When the first substrate and the second substrate are disposed opposite to each other, the liquid-repellent layer can prevent the solvent in the chamber from wetting, that is, the solvent and the particles in the solvent will not disperse on the pixel wall, thereby reducing the risk of particle loss, and further improving the display effect of the display panel.

[0135] On the other hand, the embodiment of the present application provides a method for manufacturing a display panel. Please refer to Figure 16 , Figure 16It is a flowchart of a manufacturing method of a display panel provided by an embodiment of the present application. The method includes:

[0136] Step 1601: Provide a first substrate and a second substrate.

[0137] Step 1602: Form a pixel wall on one side of the first substrate.

[0138] The pixel wall is used to enclose a plurality of separated chambers.

[0139] Step 1603: Form an electrophoretic layer in the plurality of chambers.

[0140] The electrophoretic layer has a plurality of particles.

[0141] Step 1604: Form a first bonding reaction part on at least one of the pixel wall and the second substrate.

[0142] Step 1605: Arrange the first substrate and the second substrate relatively, and form a second bonding reaction part between the first substrate and the second substrate.

[0143] The side of the first substrate facing the second substrate has a first electrode layer, and the side of the second substrate facing the first substrate has a second electrode layer. The second bonding reaction part is distributed between the pixel wall and the second substrate.

[0144] Step 1606: After the first bonding reaction part contacts the second bonding reaction part, a polymerization reaction occurs to form a sealing bonding part, enabling the second substrate to be bonded to the pixel wall through the sealing bonding part.

[0145] In summary, the embodiment of the present application provides a manufacturing method of a display panel. Among them, a first bonding reaction part is provided between the pixel wall and the second substrate, and a second bonding reaction part is provided between the first substrate and the second substrate. Since the first bonding reaction part can undergo a polymerization reaction and form a sealing bonding part after contacting the second bonding reaction part, the sealing bonding part can bond the second substrate and the pixel wall to ensure good sealing of the chamber, thereby avoiding particle migration to adjacent chambers, reducing the risk of particle loss, and further improving the display effect of the display panel.

[0146] The embodiment of the present application provides another manufacturing method of a display panel. Please refer to Figure 17 , Figure 17 It is a flowchart of another manufacturing method of a display panel provided by an embodiment of the present application. Among them, the first bonding reaction part is formed on the side of the second substrate facing the first substrate. The method includes:

[0147] Step 1701: Provide a first substrate and a second substrate.

[0148] For the preparation process of the first substrate, please refer toFigure 18 S1801 in Figure 18 is a schematic diagram of the preparation process of part of the structure in a display panel provided by an embodiment of the present application. The first substrate 10 can be obtained by forming a first electrode layer 11 on the first substrate 12. The second substrate can be obtained by forming a second electrode layer on the second substrate. The first substrate 12 and the second substrate can be flexible substrates or rigid substrates, and the embodiments of the present application do not limit this. Exemplarily, the first substrate 12 and the second substrate can both be glass substrates.

[0149] Step 1702: Form a pixel wall on one side of the first substrate.

[0150] For the preparation process of the pixel wall, please refer to Figure 18 S1802 in . The pixel wall 30 is connected to one side of the first substrate 10 and encloses a plurality of separated chambers Q1. The plurality of chambers Q1 respectively correspond to a plurality of pixels one by one, and the plurality of separated chambers Q1 are independent of each other, so that each pixel can be controlled separately.

[0151] Step 1703: Form a liquid-repellent layer on the side of the pixel wall facing away from the first substrate.

[0152] For the preparation process of the liquid-repellent layer, please refer to Figure 18 S1802 in . The liquid-repellent layer 70 is formed on the side of the pixel wall 30 facing away from the first substrate 10. Due to the liquid-repellent property of the liquid-repellent layer 70, the surface of the liquid-repellent layer 70 is not easily wetted by liquid, and the liquid-repellent layer 70 has a low surface energy and lacks attraction to liquid.

[0153] Step 1704: Form an electrophoretic layer in the plurality of chambers.

[0154] For the preparation process of the electrophoretic layer, please refer to Figure 18 S1803 in . A solvent 42 having a plurality of particles 41 is dropped into each chamber to form an electrophoretic layer 40. Due to the liquid-repellent property of the liquid-repellent layer 70, the solvent 42 is not easily distributed on the side of the pixel wall 30 facing away from the first substrate 10, thereby reducing the risk of the particles 41 remaining on the side of the pixel wall 30 facing away from the first substrate 10, further reducing the problem of particle loss, and improving the display effect.

[0155] Step 1705: Form a first bonding reaction part on at least one of the pixel wall and the second substrate.

[0156] The first bonding reaction part can be coated only on the pixel wall, or the first bonding reaction part can be coated only on the second substrate, or the first bonding reaction part is coated on the pixel wall and the second substrate.

[0157] Step 1706: Relatively arrange the first substrate and the second substrate, and form a second bonding reaction part between the first substrate and the second substrate.

[0158] Orient the side of the first substrate with the first electrode layer towards the second substrate, and orient the side of the second substrate with the second electrode layer towards the first substrate, so as to relatively arrange the first substrate and the second substrate. The second bonding reaction part can be coated on the pixel wall or the second substrate, or the second bonding reaction part can be dispersed in the solvent of the electrophoresis layer.

[0159] Step 1707: After the first bonding reaction part contacts the second bonding reaction part, a polymerization reaction occurs to form a sealing bonding part, enabling the second substrate to be bonded to the pixel wall through the sealing bonding part.

[0160] During the polymerization reaction between the first bonding reaction part and the second bonding reaction part, strong chemical bonds can be formed, so that the formed sealing bonding part has high bonding strength and density. Furthermore, the chamber can achieve good sealing performance, effectively avoiding the problem of crosstalk caused by particle movement between pixels.

[0161] It should be noted that Figure 17 The shown manufacturing method is for manufacturing a display panel that simultaneously has a liquid-repellent layer and a sealing bonding part. However, this application is not limited to this. This application can also only set a liquid-repellent layer to solve the problem of particle loss. In this case, the manufacturing method of the display panel can refer to Step 1701 to Step 1704, and will not be elaborated here.

[0162] In summary, the embodiment of this application provides a manufacturing method of a display panel. Among them, a first bonding reaction part is provided between the pixel wall and the second substrate, and a second bonding reaction part is provided between the first substrate and the second substrate. Since the first bonding reaction part can undergo a polymerization reaction and form a sealing bonding part after contacting the second bonding reaction part, the sealing bonding part can bond the second substrate and the pixel wall to ensure good sealing performance of the chamber, thereby avoiding particles from migrating to adjacent chambers. Moreover, a liquid-repellent layer is provided on the side of the pixel wall facing away from the first substrate. Since the liquid-repellent layer has liquid-repellent properties and a low surface tension. When the first substrate and the second substrate are relatively arranged, the liquid-repellent layer can prevent the solvent in the chamber from wetting, that is, the solvent and the particles in the solvent will not disperse on the pixel wall, thereby reducing the risk of particle loss and further improving the display effect of the display panel.
