Description

Technical Field

[0001] This invention relates to the field of display technology, and more specifically, to a display panel and a display device. Background Technology

[0002] Electronic paper (E-Paper) display technology is being widely used in the production of portable e-books, electronic newspapers, IC cards, and other products due to its advantages such as low power consumption, ultra-thinness, foldability, and near-paper display.

[0003] The main approaches to realizing electronic paper display technology include liquid crystal display (LCD), electrophoretic display, and electrowetting display. Among these, electrophoretic display is currently the most widely used technology. Electrophoretic display utilizes the principle of electrophoresis to move colored electrophoretic particles sandwiched between transparent electrodes under the influence of an electric field, displaying a color different from the background. These particles can alternate their movement when the direction of the electric field is changed. Compared to traditional flat panel display technology, electrophoretic display offers advantages such as low energy consumption, flexibility, high contrast, high image bistableness, good visibility, and ease of application, hence its descriptive name "electronic paper" or "electronic ink." Electrophoretic display combines the advantages of traditional paper and electronic displays, making it the most promising technology in the current field of electronic paper applications and gradually gaining widespread attention.

[0004] When designing electrophoretic display devices, the electrophoretic display solution, such as plasma containing color-developing particles, needs to be injected into different channels of the display screen to reach the pixel locations. However, the electrophoretic solution channels designed in existing technologies are prone to poor flow, causing blockages or incomplete filling of dead zones. This results in some pixel locations having a higher particle concentration in the electrophoretic solution, while other pixel locations have a lower particle count, i.e., uneven distribution of the electrophoretic solution. Consequently, the electrophoretic display screen exhibits uneven color, affecting the final display effect.

[0005] Therefore, providing a display panel and display device that can make the electrophoretic liquid in the electrophoretic display device uniformly distributed and improve the display effect is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] In view of this, the present invention provides a display panel and a display device to solve the problem of uneven plasma injection in existing electrophoretic display devices, which easily leads to uneven display.

[0007] This invention discloses a display panel, comprising: a first substrate and a second substrate disposed opposite to each other, and a plasma layer located between the first substrate and the second substrate; the plasma layer includes at least two independent first channels and a second channel, wherein plasma containing color-developing particles is disposed in the first channel and the second channel; the plasma layer includes at least a first region, wherein in the first region: the first channel includes at least a first sub-channel and a second sub-channel, the first sub-channel and the second sub-channel are disposed adjacent to each other, interconnected and both extending along a first direction; along a second direction, at least a portion of the second channel is located on the side of the first sub-channel away from the second sub-channel, and at least a portion of the second channel is disposed adjacent to the first sub-channel; at least a portion of the second channel is located on the side of the second sub-channel away from the first sub-channel, and at least a portion of the second channel is disposed adjacent to the second sub-channel; wherein the first direction and the second direction intersect.

[0008] Based on the same inventive concept, the present invention also discloses a display device, which includes the above-described display panel.

[0009] Compared with the prior art, the display panel and display device provided by the present invention achieve at least the following beneficial effects:

[0010] The display panel of the present invention can be an electrophoretic display device, comprising a first substrate and a second substrate disposed opposite to each other, with a plasma layer disposed between the first substrate and the second substrate. At least two independent first channels and second channels can be disposed in the plasma layer, and both the first channel and the second channel can be filled with plasma containing color-developing particles. In the present invention, the bending shape of the first channel and the second channel in the plasma layer is serpentine, without branching. The first channel includes at least an adjacent first sub-channel and a second sub-channel, and the first sub-channel and the second sub-channel are interconnected through a first connecting channel. The interconnected and adjacent first sub-channels and second sub-channels both extend along a first direction. When plasma containing color-developing particles is injected into the first channel, the plasma in the first sub-channel can flow smoothly and unobstructed into the second sub-channel adjacent to the first sub-channel after reaching the first connecting channel. Then, it continues to flow smoothly into the next set of first sub-channels, first connecting channels, and second sub-channels in sequence. Similarly, the shape of the second channel is designed according to the shape of the first channel, with the same bending situation. Therefore, the plasma in the second channel can also flow smoothly and unobstructed during injection. Ultimately, this ensures that the plasma fills the entire first and second channels, avoiding problems such as blockages or incomplete filling of dead corners caused by poor plasma flow. This improves the uniformity of plasma flow in its corresponding channels during injection, ensures the injection effect, and is beneficial to improving display quality.

[0011] Of course, any product implementing this invention need not necessarily achieve all of the technical effects described above at the same time.

[0043] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0044] Please refer to the reference. Figures 1-3 , Figure 1 This is a schematic diagram of the planar structure of the display panel provided in an embodiment of the present invention. Figure 2 yes Figure 1 A schematic diagram of the cross-sectional structure along the A-A' direction. Figure 3 yes Figure 1 A cross-sectional structural diagram along the B-B' direction. The display panel 000 provided in this embodiment includes: a first substrate 10 and a second substrate 20 disposed opposite to each other, and a plasma layer 30 located between the first substrate 10 and the second substrate 20.

[0045] The plasma layer 30 includes at least two independent first channels 301 and second channels 302, and plasma with color-developing particles is disposed in the first channels 301 and second channels 302.

[0046] Plasma layer 30 includes at least a first region 30A, in which:

[0047] The first channel 301 includes at least a first sub-channel 301A and a second sub-channel 301B, wherein the first sub-channel 301A and the second sub-channel 301B are arranged adjacent to each other, are interconnected, and both extend along the first direction X;

[0048] Along the second direction Y, at least a portion of the second channel 302 is located on the side of the first sub-channel 301A away from the second sub-channel 301B, and at least a portion of the second channel 302 is adjacent to the first sub-channel 301A; at least a portion of the second channel 302 is located on the side of the second sub-channel 301B away from the first sub-channel 301A, and at least a portion of the second channel 302 is adjacent to the second sub-channel 301B; wherein, the first direction X and the second direction Y intersect. Optionally, in this embodiment, the first direction X and the second direction Y are perpendicular to each other as an example for illustration.

[0049] Specifically, the display panel 000 in this embodiment can be an electrophoretic display device. Generally, the principle of electrophoretic display technology relies on the movement of charged particles immersed in plasma. The sub-pixels are brightened or darkened by the flipping or flowing of these charged particles. Typically, two substrates are arranged opposite each other, each with electrodes forming a control electric field. The electric field strength between the opposing electrodes is controlled by the voltage on the electrodes. Consequently, charged particles in the plasma migrate from their current location to the electrode with the opposite charge via electrophoresis. For example, if there are white or black charged particles in the plasma, when a white particle moves to the front of the display panel, white is displayed; when a black particle is on the front of the display panel, black is displayed; and when black and white particles are evenly distributed on the front of the display panel, gray is displayed, thus realizing electrophoretic display technology.

[0050] The display panel 000 of this embodiment includes a first substrate 10 and a second substrate 20 disposed opposite to each other. Optionally, the first substrate 10 and the second substrate 20 can be rigid materials such as glass with high light transmittance or flexible materials such as polyimide. A plasma layer 30 is disposed between the first substrate 10 and the second substrate 20. At least two independent first channels 301 and second channels 302 can be disposed in the plasma layer 30 (the independent first channels 301 and second channels 302 are distinguished by different filling patterns in the figure). Both the first channels 301 and the second channels 302 can be filled with plasma containing color-developing particles (not shown in the figure). It is understood that in this embodiment, the color of the color-developing particles in the first channel 301 and the color of the color-developing particles in the second channel 302 are not limited. The color of the color-developing particles in the first channel 301 and the color of the color-developing particles in the second channel 302 can be the same, such as both being black color-developing particles, both being white color-developing particles, or both being color-developing particles of other colors. When displaying an image, the display brightness can be controlled by controlling the distribution concentration of particles in the plasma, thereby realizing the image display. Alternatively, the colors of the color-developing particles in the first channel 301 and the second channel 302 can be different. For example, if the color-developing particles in the first channel 301 are black, then the color-developing particles in the second channel 302 can be white or other colors. Or, if the color-developing particles in the first channel 301 are white, then the color-developing particles in the second channel 302 can be black or other colors. When displaying an image, the distribution positions of different colored particles in the plasma can be controlled. As described above, when white color-developing particles move to the light-emitting surface of the display panel 000, white is displayed; when black color-developing particles move to the light-emitting surface of the display panel 000, black is displayed; when black and white color-developing particles are evenly distributed on the light-emitting surface of the display panel 000, gray is displayed, thus achieving the display function. It is understood that in this embodiment, the light-emitting surface of the display panel 000 can be the surface of the second substrate 20 away from the first substrate 10.

[0051] It should be noted that this embodiment does not specifically limit the distribution and color of the color-developing particles in the plasma layer 30 of the display panel 000. It is only required that the two independent first channels 301 and second channels 302 of the plasma layer 30 are filled with plasma containing color-developing particles.

[0052] In this embodiment, the plasma layer 30 includes at least a first region 30A, optionally, such as Figure 1As shown, the first region 30A can be understood as all areas reachable by the first channel 301 and the second channel 302 of the plasma layer 30. In the first region 30A, the first channel 301 includes at least two adjacent sub-channels 301A and 301B, which are interconnected. The adjacent arrangement of the interconnected sub-channels 301A and 301B means that there are no other plasma channels between them; they are tightly packed together. Both the interconnected and adjacent sub-channels 301A and 301B extend along the first direction X, meaning they extend in the same direction. For example, both extend along the first direction X. It is understandable that, since the first sub-channel 301A and the second sub-channel 301B extend in the same direction and need to be interconnected, optionally, along the first direction X, at the same end of the first sub-channel 301A and the second sub-channel 301B, the first channel 301 may also include a first connecting channel 301L to achieve interconnection between the first sub-channel 301A and the second sub-channel 301B. Furthermore, since the first sub-channel 301A and the second sub-channel 301B are arranged adjacent to each other, the length of the first connecting channel 301L in the arrangement direction of the first sub-channel 301A and the second sub-channel 301B (as shown in the second direction Y) is relatively short, generally equal to the sum of the widths of the first sub-channel 301A and the second sub-channel 301B in the arrangement direction of the first sub-channel 301A and the second sub-channel 301B (as shown in the second direction Y). Depending on the size of the display panel 000, multiple sets of structures of the first sub-channel 301A, the first connecting channel 301L, and the second sub-channel 301B can be generated along the second direction Y. Figure 1(This example only uses three groups as illustrations.) These groups are interconnected to form the first channel 301, ensuring that the plasma within the first channel 301 reaches as much of the display panel 000 as possible. In the first area 30A, if the first channel 301 has the above structure, the second channel 302 can be arranged according to the bending path of the first channel 301. Specifically, along the second direction Y, at least a portion of the second channel 302 is located on the side of the first sub-channel 301A away from the second sub-channel 301B, and at least a portion of the second channel 302 is adjacent to the first sub-channel 301A, meaning there are no other plasma channels between the adjacent portion of the second channel 302 and the first sub-channel 301A; at least a portion of the second channel 302 is located on the side of the second sub-channel 301B away from the first sub-channel 301A, and at least a portion of the second channel 302 is adjacent to the second sub-channel 301B, meaning there are no other plasma channels between the adjacent portion of the second channel 302 and the second sub-channel 301B. It is understandable that, since the second channel 302 is a complete plasma channel and is designed based on the shape of the first channel 301, the second channel 302 may also include two interconnected sub-channels and a connecting channel (not labeled in the figure) connecting the two sub-channels. Depending on the size of the display panel 000, along the second direction Y, the second channel 302 may also have a structure with multiple sets of sub-channels and connecting channels to form the second channel 302, so as to enable the plasma in the second channel 302 to reach the entire display panel 000 area as much as possible.

[0053] In this embodiment, the first channel 301 and the second channel 302 of the plasma layer 30 are both serpentine and without branching. When the plasma containing color-developing particles is injected into the first channel 301, the plasma in the first sub-channel 301A can flow smoothly and unobstructed into the second sub-channel 301B adjacent to the first sub-channel 301A after reaching the position of the first connecting channel 301L. Then, it continues to flow smoothly to the next group of first sub-channels 301A, first connecting channels 301L, and second sub-channels 301B in sequence. Similarly, the shape of the second channel 302 is designed according to the shape of the first channel 301, with the same bending situation. Therefore, the plasma in the second channel 302 can also flow smoothly and unobstructed when injected. Ultimately, it can ensure that the plasma fills the entire first channel 301 and the second channel 302, which can avoid the problem of blockage or incomplete filling of dead corners caused by poor plasma flow. This can improve the uniformity of plasma flow in its corresponding channel during injection, ensure the injection effect, and improve the display quality.

[0054] It is understood that this embodiment is only an example to illustrate the structure of the display panel 000. In specific implementation, the structure of the electrophoretic display panel includes, but is not limited to, this. It may also include other structures that can achieve the electrophoretic display effect, such as an electrode layer that provides an electric field, a sealant that seals the plasma channel, etc. For details, please refer to the structure of the electrophoretic display panel in related technologies. This embodiment will not elaborate on it here.

[0055] Optional, such as Figure 4 and Figure 5 As shown, Figure 4 This is a schematic diagram of another planar structure of the display panel provided in an embodiment of the present invention. Figure 5 yes Figure 4 A cross-sectional view along the C-C' direction is shown in this embodiment. The display panel 000 further includes a first electrode layer 40 and a second electrode layer 50. The first electrode layer 40 is located on the side of the first substrate 10 facing the plasma layer 30 and includes a plurality of first electrodes 401. The second electrode layer 50 is disposed on the side of the second substrate 20 facing the plasma layer 30.

[0056] The display panel 000 includes multiple sub-pixels PX, and the first electrode 401 corresponds to each sub-pixel PX.

[0057] This embodiment explains that the display panel 000 may also include opposing electrode layers for forming an electric field that controls the movement of color particles in the control channel. Specifically, a first electrode layer 40 is provided on the side of the first substrate 10 facing the plasma layer 30. The first electrode layer 40 includes a plurality of patterned first electrodes 401, and each first electrode 401 corresponds one-to-one with a sub-pixel PX, that is, one sub-pixel PX corresponds to one first electrode 401. Thus, by transmitting different voltage values ​​to the first electrode 401, different movement positions of color particles within the range of different sub-pixels PX can be achieved, thereby realizing individual control of the display brightness of the sub-pixel PX. A second electrode layer 50 is disposed on the side of the second substrate 20 facing the plasma layer 30. The second electrode layer 50 is a full-surface structure. It can be understood that the second electrode layer 50 can be understood as a common electrode layer, and the first electrode layer 40 can be understood as a pixel electrode layer. An electric field can be formed between the first electrode 401 and the second electrode layer 50 in different sub-pixel PX regions. In the first channel 301 and / or the second channel 302, multiple charged color particles can generate different aggregations on the side near the light-emitting surface of the display panel 000 due to the different electric fields between the first electrode 401 and the second electrode layer 50 (in this embodiment, the light-emitting surface of the display panel 000 can be the surface of the second substrate 20 away from the first substrate 10), thereby presenting a black or white display effect. Furthermore, by setting different voltage values ​​for the first electrode 401 in different sub-pixel PX regions, the electric field intensity of different sub-pixel PX regions can be made different, thereby resulting in different aggregation densities of color particles at different sub-pixel PX regions on the side near the light-emitting surface of the display panel 000, achieving a change in grayscale brightness.

[0058] It is understood that this embodiment does not elaborate on the movement mode of the color particles in the first channel 301 and the second channel 302 of the plasma layer 30. For details, please refer to the display principle of the electrophoretic display panel in the related art.

[0059] Optionally, in this embodiment, the color of the color-developing particles in the first channel 301 is different from the color of the color-developing particles in the second channel 302. For example, the color of the color-developing particles in the first channel 301 can be black, and the color of the color-developing particles in the second channel 302 can be white, or the color of the color-developing particles in the first channel 301 can be white, and the color of the color-developing particles in the second channel 302 can be black. Black color particles are negatively charged, and white color particles are positively charged. Taking the color particles in the first channel 301 as black and the color particles in the second channel 302 as white, when the electric field formed between the first electrode 401 and the second electrode layer 50 in the sub-pixel PX corresponding to the first channel 301 is such that the first electrode 401 points towards the second electrode layer 50, the black color particles in the sub-pixel PX corresponding to the first channel 301 move to the side away from the light-emitting surface of the display panel 000, that is, closer to the first substrate 10, and the sub-pixel PX displays a light black color. When the electric field formed between the first electrode 401 and the second electrode layer 50 in the sub-pixel PX corresponding to the first channel 301 is such that the second electrode layer 50 points towards the first electrode 401, the black color particles in the sub-pixel PX corresponding to the first channel 301 move to the side closer to the light-emitting surface of the display panel 000, that is, closer to the second substrate 20, and the sub-pixel PX displays a black color. When the electric field formed between the first electrode 401 and the second electrode layer 50 in the sub-pixel PX corresponding to the second channel 302 is such that the first electrode 401 points towards the second electrode layer 50, then the white color-producing particles in the sub-pixel PX corresponding to the second channel 302 move to the side closer to the light-emitting surface of the display panel 000, that is, closer to the second substrate 20, and the sub-pixel displays white. When the electric field formed between the first electrode 401 and the second electrode layer 50 in the sub-pixel PX corresponding to the second channel 302 is such that the second electrode layer 50 points towards the first electrode 401, then the white color-producing particles in the sub-pixel PX corresponding to the second channel 302 move to the side farther away from the light-emitting surface of the display panel 000, that is, closer to the first substrate 10, and the sub-pixel PX displays dark white. It is understood that this embodiment is only an example illustrating one display principle of the display panel 000. In specific implementation, the display function may include, but is not limited to, this, and may also be other display methods. This embodiment does not specifically limit this.

[0060] Optional, such as Figure 1 and Figure 4As shown, in this embodiment, the second channel 302 has an S-shaped orthographic projection onto the plane of the first substrate 10; at least a portion of the second channel 302 is arranged around the first channel 301. This embodiment explains that the bend in the first channel 301 is serpentine, allowing the first sub-channel 301A and the second sub-channel 301B of the first channel 301 to be adjacent and extend in the same direction. This ensures that plasma injected into the first sub-channel 301A can flow continuously and smoothly through the first connecting channel 301L into the second sub-channel 301B after being injected into one end of the first sub-channel 301A, thereby achieving uniform plasma injection. The shape of the second channel 302 follows the bend of the first channel 301, so that the orthographic projection of the second channel 302 onto the plane of the first substrate 10 is S-shaped; at least a portion of the second channel 302 is arranged around the first channel 301, thus ensuring continuous and smooth plasma injection within the second channel 302 while maintaining uniform plasma injection within the second channel 302.

[0061] In some alternative embodiments, please refer to the references. Figures 6-8 , Figure 6 This is a schematic diagram of another planar structure of the display panel provided in an embodiment of the present invention. Figure 7 yes Figure 6 A schematic diagram of the cross-sectional structure along the D-D' direction. Figure 8 yes Figure 6 A cross-sectional structural diagram along the E-E' direction. In this embodiment, the first area 30A includes a display area AA and a non-display area NA that is at least partially surrounding the display area AA.

[0062] In the display area AA, along the first direction X, the length L1 of the first channel 301 is equal to the length L2 of the second channel 302.

[0063] This embodiment explains that in the display panel 000, the plasma layer 30 includes a first region 30A, which may include at least a display area AA and a non-display area NA surrounding the display area AA. That is, the first region 30A is not entirely a display area; some areas do not have sub-pixels or are not displayed. Furthermore, in the region where the display area AA is located, along the first direction X, i.e., along the length extension direction of the first sub-channel 301A and the second sub-channel 301B, the length L1 of the first channel 301 is equal to the length L2 of the second channel 302. This allows the lengths of the first channel 301 and the second channel 302, which contain different color-coding particles, to be consistent in the first direction X. This facilitates the formation of complete pixels when the display panel 000 is used for display, thereby improving display quality.

[0064] It is understandable that when the first region 30A includes the display region AA and the non-display region NA, the first electrode layer 40 and the second electrode layer 50 can be located only within the display region AA, which helps to save manufacturing costs.

[0065] Optional, such as Figure 9 and Figure 10 As shown, Figure 9 This is a schematic diagram of another planar structure of the display panel provided in an embodiment of the present invention. Figure 10 yes Figure 9 A cross-sectional structural diagram along the F-F' direction (it should be understood that this diagram is for the purpose of clearly illustrating the structure of this embodiment). Figure 9 (Transparency filling is performed in the middle). In this embodiment, the non-display area NA of the display panel 000 includes a light-shielding layer 60, which surrounds the display area AA.

[0066] This embodiment explains that a light-shielding layer 60 can be provided in the non-display area NA of the display panel 000 to provide a light-shielding effect to the non-display area NA. Optionally, the light-shielding layer 60 can be located on the side of the second substrate 20 facing the first substrate 10, and the light-shielding layer 60 is disposed around at least part of the display area AA, so that the light-shielding layer 60 can block part of the first channel 301 and the second channel 302, so that the length of each channel along the first direction X in the display area AA is equal, thus ensuring display quality.

[0067] Alternatively, the light-shielding layer 60 can be made of ink material, which not only has good light-shielding performance but also occupies a thin layer, thus avoiding affecting the overall thickness of the panel.

[0068] In some alternative embodiments, please refer to the references. Figure 9 and Figure 11 , Figure 11 yes Figure 9 A cross-sectional structural diagram along the G-G' direction is shown in this embodiment. In the first region 30A, along the second direction Y, the width W1 of the first channel 301 is different from the width W2 of the second channel 302.

[0069] This embodiment explains that the widths of the first channel 301 and the second channel 302 carrying color-developing particles can be different. If the concentrations of color-developing particles in different channels are different, the width of that channel can be set to be wider. Specifically, if the concentration of plasma-carried color-developing particles in the first channel 301 is less than the concentration of plasma-carried color-developing particles in the second channel 302, then along the second direction Y, the width W1 of the first channel 301 can be greater than the width W2 of the second channel 302; if the concentration of plasma-carried color-developing particles in the first channel 301 is greater than the concentration of plasma-carried color-developing particles in the second channel 302, then along the second direction Y, the width W1 of the first channel 301 can be less than the width W2 of the second channel 302. The widths of different channels can be specifically set according to the concentration and color purity of the color-developing particles, thereby ensuring the display effect through the flexible design of the channels in the plasma layer 30.

[0070] In some alternative embodiments, please refer to Figure 12 , Figure 12 This is a schematic diagram of another planar structure of the display panel provided in an embodiment of the present invention. In this embodiment, the first area 30A includes at least two vertices, the first channel 301 includes a first input end 3011 and a first sealing end 3012, and the second channel 302 includes a second input end 3021 and a second sealing end 3022. The first input end 3011 and the second input end 3021 are located at different vertex positions of the first area 30A.

[0071] This embodiment explains that each channel of the plasma layer 30 can include an input end and a sealing end. The input end serves as the inlet for plasma injection, and the sealing end is used to apply sealing adhesive 70. One end of a channel is the input end, and the other end is the sealing end sealed with sealing adhesive 70, allowing for timely venting during plasma injection and ensuring the uniformity of the plasma within the channel. Furthermore, this embodiment sets the first input end 3011 of the first channel 301 and the second input end 3021 of the second channel 302 at different vertices of the first region 30A, meaning the injection ports of the two channels are not at the same vertices of the first region 30A. This facilitates the differentiation between the input ends of the first channel 301 and the second channel 302, preventing channel confusion during plasma injection.

[0072] Optionally, after the plasma filling in each channel of the plasma layer 30 is completed, the first input terminal 3011 and the second input terminal 3021 can also be sealed to ensure the airtightness of the plasma layer 30.

[0073] In some alternative embodiments, please refer to the references. Figure 13 , Figure 14 and Figure 15 , Figure 13 This is a schematic diagram of another planar structure of the display panel provided in an embodiment of the present invention. Figure 14 yes Figure 13 A schematic diagram of the cross-sectional structure along the H-H' direction. Figure 15 yes Figure 13 A cross-sectional structural diagram along the I-I' direction is shown. In this embodiment, the plasma layer 30 further includes a third channel 303, which contains plasma with color-developing particles. The color-developing particles in the third channel 303, the first channel 301, and the second channel 302 are of different colors (distinguished by different filling patterns in the diagram); in the first region 30A:

[0074] The third channel 303 includes at least a third sub-channel 303A and a fourth sub-channel 303B. The third sub-channel 303A and the fourth sub-channel 303B are arranged adjacent to each other, connected to each other, and both extend along the first direction X.

[0075] Along the second direction Y, at least a portion of the second channel 302 is located on the side of the third sub-channel 303A away from the fourth sub-channel 303B, and at least a portion of the second channel 302 is arranged adjacent to the third sub-channel 303A; at least a portion of the second channel 302 is located on the side of the fourth sub-channel 303B away from the third sub-channel 303A, and at least a portion of the second channel 302 is arranged adjacent to the fourth sub-channel 303B.

[0076] At least part of the second channel 302 is arranged around the third channel 303.

[0077] This embodiment explains that the plasma layer 30 of the display panel 000 can have at least three channels for displaying particles of different colors to achieve a full-color display effect. Specifically, the plasma layer 30 also includes a third channel 303, which is provided with plasma containing color-developing particles. The color-developing particles in the third channel 303, the first channel 301, and the second channel 302 are different colors, such as red, green, and blue, respectively. In the first region 30A of the plasma layer 30, the shape of the third channel 303 can be bent according to the shape of the second channel 302. For example, the third channel 303 includes at least two adjacent sub-channels 303A and 303B, and the third sub-channels 303A and 303B are interconnected. The adjacent arrangement of the interconnected third sub-channels 303A and 303B can be understood as meaning that there are no other plasma channels between the third sub-channels 303A and 303B, and they are closely adjacent to each other. The interconnected and adjacent third sub-channels 303A and 303B both extend along the first direction X, that is, their extension directions are the same. Taking the first direction X as an example, both extend along the first direction X. Understandably, since the third sub-channel 303A and the fourth sub-channel 303B extend in the same direction and need to be interconnected, optionally, along the first direction X, at the same end of the third sub-channel 303A and the fourth sub-channel 303B, the third channel 303 can also include a third connecting channel 303L to achieve interconnection between the third sub-channel 303A and the fourth sub-channel 303B. Furthermore, since the third sub-channel 303A and the fourth sub-channel 303B are arranged adjacent to each other, the length of the third connecting channel 303L in the arrangement direction of the third sub-channel 303A and the fourth sub-channel 303B (as shown in the second direction Y) is shorter, generally equal to the sum of the widths of the third sub-channel 303A and the fourth sub-channel 303B in the second direction Y. Depending on the size of the display panel 000, there can be multiple sets of structures with the third sub-channel 303A, the third connecting channel 303L, and the fourth sub-channel 303B along the second direction Y. Figure 13(This example only uses three groups as an illustration). These groups are interconnected to form a third channel 303, ensuring that the plasma within the third channel 303 reaches as much of the display panel 000 as possible. In this embodiment, the relationship between the third channel 303 and the second channel 302 is that the bend in the third channel 303 can be based on the bend shape of the second channel 302. Along the second direction Y, at least a portion of the second channel 302 is located on the side of the third sub-channel 303A away from the fourth sub-channel 303B, and at least a portion of the second channel 302 is adjacent to the third sub-channel 303A, meaning there are no other plasma channels between the adjacent portion of the second channel 302 and the third sub-channel 303A; at least a portion of the second channel 302 is located on the side of the fourth sub-channel 303B away from the third sub-channel 303A, and at least a portion of the second channel 302 is adjacent to the fourth sub-channel 303B. The arrangement is such that at least a portion of the second channel 302 and the fourth sub-channel 303B are arranged adjacently without any other plasma channels, forming a structure in which at least a portion of the second channel 302 surrounds the third channel 303. In the first region 30A, along the second direction Y, the first sub-channel 301A and the second sub-channel 301B are arranged adjacently to form a first group of channels 3010, and the third sub-channel 303A and the fourth sub-channel 303B are arranged adjacently to form a second group of channels 3030. The second channel 302 is located between the first group of channels 3010 and the second group of channels 3030. It can also be understood that the first channel 301 and the third channel 303 are both arranged according to the bending shape of the second channel 302.

[0078] This embodiment sets up three plasma channels, and the color of the color-developing particles in different channels is different. Further optionally, the first channel 301, the second channel 302, and the third channel 303 can each include two colors of color-developing particles. For example, the plasma in the first channel 301 can be a plasma including black color-developing particles and red color-developing particles, the plasma in the second channel 302 can be a plasma including black color-developing particles and green color-developing particles, and the plasma in the third channel 303 can be a plasma including black color-developing particles and blue color-developing particles.

[0079] When the display panel 000 achieves full-color display, the surface of the second substrate 20 away from the first substrate 10 is taken as the light-emitting surface of the display panel 000 as an example. Black color particles are negatively charged, red color particles are positively charged, green color particles are positively charged, and blue color particles are positively charged.

[0080] When the electric field formed between the first electrode 401 and the second electrode layer 50 in the sub-pixel PX corresponding to the first channel 301 is such that the first electrode 401 points towards the second electrode layer 50, then in the sub-pixel PX corresponding to the first channel 301, red color particles move to the side closer to the light-emitting surface of the display panel 000, that is, closer to the second substrate 20, and black color particles move to the side farther away from the light-emitting surface of the display panel 000, that is, closer to the first substrate 10, and the sub-pixel PX displays red; when the electric field formed between the first electrode 401 and the second electrode layer 50 in the sub-pixel PX corresponding to the first channel 301 is such that the second electrode layer 50 points towards the first electrode 401, then in the sub-pixel PX corresponding to the first channel 301, red color particles move to the side farther away from the light-emitting surface of the display panel 000, that is, closer to the first substrate 10, and black color particles move to the side closer to the light-emitting surface of the display panel 000, that is, closer to the second substrate 20, and the sub-pixel PX displays black.

[0081] When the electric field formed between the first electrode 401 and the second electrode layer 50 in the sub-pixel PX corresponding to the second channel 302 is such that the first electrode 401 points towards the second electrode layer 50, then in the sub-pixel PX corresponding to the second channel 302, green color particles move to the side closer to the light-emitting surface of the display panel 000, that is, closer to the second substrate 20, and black color particles move to the side farther away from the light-emitting surface of the display panel 000, that is, closer to the first substrate 10, and the sub-pixel PX displays green; when the electric field formed between the first electrode 401 and the second electrode layer 50 in the sub-pixel PX corresponding to the second channel 302 is such that the second electrode layer 50 points towards the first electrode 401, then in the sub-pixel PX corresponding to the second channel 302, green color particles move to the side farther away from the light-emitting surface of the display panel 000, that is, closer to the first substrate 10, and black color particles move to the side closer to the light-emitting surface of the display panel 000, that is, closer to the second substrate 20, and the sub-pixel PX displays black.

[0082] When the electric field formed between the first electrode 401 and the second electrode layer 50 in the sub-pixel PX corresponding to the third channel 303 is such that the first electrode 401 points towards the second electrode layer 50, then in the sub-pixel PX corresponding to the third channel 303, blue color particles move to the side closer to the light-emitting surface of the display panel 000, that is, closer to the second substrate 20, and black color particles move to the side farther away from the light-emitting surface of the display panel 000, that is, closer to the first substrate 10, and the sub-pixel PX displays blue; when the electric field formed between the first electrode 401 and the second electrode layer 50 in the sub-pixel PX corresponding to the third channel 303 is such that the second electrode layer 50 points towards the first electrode 401, then in the sub-pixel PX corresponding to the third channel 303, blue color particles move to the side farther away from the light-emitting surface of the display panel 000, that is, closer to the first substrate 10, and black color particles move to the side closer to the light-emitting surface of the display panel 000, that is, closer to the second substrate 20, and the sub-pixel PX displays black.

[0083] Based on the above principle, the display color of each sub-pixel PX can be adjusted by controlling the electric field direction or electric field intensity of the sub-pixel PX corresponding to different color channels by controlling the voltage applied to the first electrode 401 corresponding to each sub-pixel PX, thereby achieving full-color display of the image. Furthermore, in this embodiment, the first channel 301, the second channel 302, and the third channel 303 are all arranged along a direction parallel to the plane of the first substrate 10, achieving full-color display without channel superposition, which is beneficial for reducing the overall thickness of the panel.

[0084] Optional, such as Figure 16 and Figure 17 As shown, Figure 16 This is a schematic diagram of another planar structure of the display panel provided in an embodiment of the present invention. Figure 17 yes Figure 16A cross-sectional structural diagram along the J-J' direction is shown. In this embodiment, the display panel 000 includes a plasma layer 30 comprising a first channel 301, a second channel 302, and a third channel 303, each carrying different colored color-developing particles. The first region 30A includes a display region AA and a non-display region NA, which is at least partially surrounding the display region AA. In the display region AA, along the first direction X, the lengths L1 of the first channel 301, L2 of the second channel 302, and L3 of the third channel 303 are equal. The non-display region NA of the display panel 000 includes a light-shielding layer 60, which surrounds the display region AA. The first zone 30A includes three vertices. The first channel 301 includes a first input terminal 3011 and a first sealing terminal 3012. The second channel 302 includes a second input terminal 3021 and a second sealing terminal 3022. The third channel 303 includes a third input terminal 3031 and a third sealing terminal 3032. The first input terminal 3011, the second input terminal 3021, and the third input terminal 3031 are located at different vertex positions of the first zone 30A. Sealing adhesive 70 is provided at the first sealing terminal 3012, the second sealing terminal 3022, and the third sealing terminal 3032. That is, when the display panel 000 includes three channels to achieve full-color display, it can also have the structure in the above embodiment. This embodiment does not elaborate on the effects of the above structure. For details, please refer to the description of the above embodiment for understanding.

[0085] For further options, please refer to the reference. Figure 16 and Figure 18 , Figure 18 yes Figure 16 A cross-sectional structural diagram along the K-K' direction is shown in this embodiment. In the first region 30A, along the second direction Y, the width W1 of the first channel 301 is different from the width W2 of the second channel 302. The widths of the first channel 301, the second channel 302, and the third channel 303 in the first region 30A along the second direction Y can also be designed to be different according to actual display requirements. For example, the first channel 301 may contain red plasma particles, the second channel 302 may contain green plasma particles, and the third channel 303 may contain blue plasma particles.

[0086] Along the second direction Y, the width W2 of the second channel 302 is greater than the width W1 of the first channel 301, and the width W1 of the first channel 301 is greater than the width W2 of the third channel 303.

[0087] This embodiment explains that the widths of the first channel 301, the second channel 302, and the third channel 303 containing color-developing particles can be different. Generally, the width of different channels can be set by referring to the concentration of color-developing particles in different color channels and the color purity of the color-developing particles themselves. For example, considering the ratio of luminous flux in white light, red:green:blue = 1:4.5907:0.0601 (white light can be obtained by adding the three primary colors of red, green, and blue, and the ratio of luminous flux of the three in white light is R:G:B = 1:4.5907:0.0601, that is, if we usually take red primary color light with a luminous flux of 1 watt as the benchmark, then to produce white light, we need 4.5907 watts of green light and 0.0601 watts of blue light), in order to make the luminous flux of green light larger, we can set the width of the second channel 302 with green color particles to be the largest, and the width of the third channel 303 with blue color particles to be the smallest. That is, along the second direction Y, the width W2 of the second channel 302 is greater than the width W1 of the first channel 301, and the width W1 of the first channel 301 is greater than the width W2 of the third channel 303. This can effectively achieve the display uniformity of the display panel and ensure the display life of the display panel.

[0088] In some alternative embodiments, please refer to the references. Figure 19 and Figure 20 , Figure 19 This is a schematic diagram of another planar structure of the display panel provided in an embodiment of the present invention. Figure 20 This is a schematic diagram of another planar structure of the display panel provided in an embodiment of the present invention. In this embodiment, the plasma layer 30 further includes at least a second region 30B, in which:

[0089] The first channel 301 includes at least a fifth sub-channel 301C and a sixth sub-channel 301D. The fifth sub-channel 301C and the sixth sub-channel 301D are arranged adjacent to each other, connected to each other, and both extend along the second direction Y.

[0090] Along the first direction X, at least a portion of the second channel 302 is located on the side of the fifth sub-channel 301C away from the sixth sub-channel 301D, and at least a portion of the second channel 302 is arranged adjacent to the fifth sub-channel 301C; at least a portion of the second channel 302 is located on the side of the sixth sub-channel 301D away from the fifth sub-channel 301C, and at least a portion of the second channel 302 is arranged adjacent to the sixth sub-channel 301D.

[0091] This embodiment explains that the plasma layer 30 of the display panel 000 includes not only the first region 30A, but also the second region 30B. The bending of the channels in the plasma layer 30 of the second region 30B is different from that in the plasma layer 30 of the first region 30. Optionally, the bending direction of the channels in the plasma layer 30 of the second region 30B is opposite to that of the channels in the plasma layer 30 of the first region 30. In the specific second zone 30B, the first channel 301 includes at least a fifth sub-channel 301C and a sixth sub-channel 301D. The fifth sub-channel 301C and the sixth sub-channel 301D are arranged adjacently and connected to each other. That is, there are no other channels between the fifth sub-channel 301C and the sixth sub-channel 301D. They are also arranged adjacently after being bent through a connecting channel. Unlike the first sub-channel 301A and the second sub-channel 301B in the first zone 30A, which extend along the first direction X, the fifth sub-channel 301C and the sixth sub-channel 301D in the second zone 30B both extend along the second direction Y. Furthermore, the second channel 302 within the second zone 30B is also bent according to the bending paths of the fifth sub-channel 301C and the sixth sub-channel 301D of the first channel 301, thus forming a configuration where, along the first direction X, at least a portion of the second channel 302 is located on the side of the fifth sub-channel 301C away from the sixth sub-channel 301D, and the second channel 302 on the side away from the sixth sub-channel 301D is adjacent to the fifth sub-channel 301C, with no other channels between them; at least a portion of the second channel 302 is located on the side of the sixth sub-channel 301D away from the fifth sub-channel 301C, and the second channel 302 on the side of the sixth sub-channel 301D away from the fifth sub-channel 301C is adjacent to the sixth sub-channel 301D. There are no other channels between them, which means that the serpentine channel in the display panel 000 is not only folded and bent in one direction. At least the bending directions of the serpentine channel in the first area 30A and the serpentine channel in the second area 30B are intersecting or perpendicular to each other. Since the channel wall itself blocks the movement in a single direction, the influence of gravity or centrifugal force on the movement of color particles in one direction can be reduced to a certain extent. When focusing on plasma with color particles, the channel wall itself blocks the movement in a single direction, which can control the color particles to move only within a small range, avoiding the problem of uneven pouring caused by all of them gathering at a certain edge. This is conducive to further improving the plasma pouring effect and improving the display quality.

[0092] It is understood that in this embodiment Figure 19 This example only uses the plasma layer 30, including the first channel 301 and the second channel 302, as an illustration. Figure 20 As shown, the plasma layer 30 may also include a third channel 303, and the colors of the color-developing particles in the three channels can be different. In this case, the third channel 303 in the second region 30B can be configured as follows: Figure 20 As shown, the bending shape of the second channel 302 in the second zone 30B is set, and the bending direction is different from that of the third channel 303 in the first zone 30A. This achieves uniform plasma filling of the display panel 000 while realizing a full-color display effect. This embodiment will not be described in detail here.

[0093] Optionally, in some other embodiments, the number of first areas 30A and second areas 30B included in the display panel 000 may include, but is not limited to, the following: Figure 19 and Figure 20 As shown, the specific settings can be determined based on the size of the display panel 000, the length of the channel extending in a single direction, or the width of the channel itself. Figure 19 and Figure 20 This example uses a display panel 000, which includes one first zone 30A and two second zones 30B, as an illustration.

[0094] Optional, such as Figure 19 As shown, the display panel 000 may include at least four vertices. The first channel 301 includes a first input end 3011 and a first sealing end 3012. The second channel 302 includes a second input end 3021 and a second sealing end 3022. The first input end 3011 and the second input end 3021 are located at different vertex positions of the display panel 000. Sealing adhesive 70 is provided at both the first sealing end 3012 and the second sealing end 3022. That is, when the display panel 000 includes the first area 30A and the second area 30B to jointly realize a complete channel, the input end and the sealing end of the channel are located at the vertex positions of the display panel 000. This embodiment does not elaborate on the effects of the above structure; please refer to the description of the above embodiment for a detailed understanding. Figure 20 As shown, the display panel 000 may include at least four vertices. The first channel 301 includes a first input terminal 3011 and a first sealing terminal 3012. The second channel 302 includes a second input terminal 3021 and a second sealing terminal 3022. The third channel 303 includes a third input terminal 3031 and a third sealing terminal 3032. The first input terminal 3011, the second input terminal 3021, and the third input terminal 3031 are located at different vertex positions of the display panel 000. Sealing adhesive 70 is provided at the first sealing terminal 3012, the second sealing terminal 3022, and the third sealing terminal 3032. That is, the display panel 000 includes the first area 30A and the second area 30B to jointly realize a complete channel. When full-color display is achieved through three channels with different colors, the input terminal and the sealing terminal of the channel are located at the vertex position of the display panel 000. This embodiment does not elaborate on the effect of the above structure. For details, please refer to the description of the above embodiment for understanding.

[0095] In some alternative embodiments, please refer to Figure 21 and Figure 22 , Figure 21 This is a schematic diagram of another planar structure of the display panel provided in an embodiment of the present invention. Figure 22 yes Figure 21 A schematic diagram of the planar structure of the second channel is shown. In this embodiment, the shape of the orthographic projection of the second channel 302 onto the plane where the first substrate 10 is located is a Peano curve shape.

[0096] This embodiment explains that the display panel 000 includes a first channel 301, a second channel 302, and a third channel 303. The plasma particles in the first channel 301, second channel 302, and third channel 303 carry different colors to achieve full-color display. Figure 22 As shown, the shape of the orthographic projection of the second channel 302 onto the plane of the first substrate 10 can be set to a Peano curve shape. Since the bending shapes of the first channel 301 and the third channel 303 can be set according to the bending path of the second channel 302, setting the shape of the orthographic projection of the second channel 302 onto the plane of the first substrate 10 to a Peano curve shape allows the shapes of the other two channels of the plasma layer 30 to also be determined to be Peano curve shapes. Optionally, the second channel 302 includes a second input end 3021 and a second sealing end 3022, with the second input end 3021 and the second sealing end 3022 located diagonally opposite each other on the display panel 000. A Peano curve is a curve that can fill a square. Therefore, setting the shape of the plasma channel in the display panel 000 to a Peano curve shape allows the channel of the plasma layer 30 to fill the entire area of ​​the display panel as much as possible. Even when affected by gravity or centrifugal force, the movement of color particles in the channel will be blocked by the channel wall itself of the Peano curve shape, so that the color particles can only move within a small range. This prevents the color particles from all gathering at a certain edge or position. Furthermore, when the light-emitting surface of the display panel 000 is used perpendicular to the ground, regardless of whether the light-emitting surface of the display panel 000 is rotated, the influence of gravity on the distribution of color particles can be reduced more effectively, which is beneficial to improving display uniformity and enhancing display quality.

[0097] In some alternative embodiments, please refer to the references. Figure 1 and Figure 23 , Figure 23 yes Figure 1 Another cross-sectional structural diagram along the A-A' direction. In this embodiment, a first partition wall 801 is included between the first sub-channel 301A and the second sub-channel 301B of the first channel 301, and a second partition wall 802 is included between the first sub-channel 301A and the second channel 302.

[0098] The thickness D1 of the first partition wall 801 is less than the thickness D2 of the second partition wall 802.

[0099] This embodiment explains that when the plasma layer 30 of the display panel 000 includes at least two channels, namely the first channel 301 and the second channel 302, the first channel 301 includes a first partition wall 801 between the adjacent and interconnected first sub-channels 301A and 301B. Optionally, the thickness D1 of the first partition wall 801 can be understood as the sum of the thicknesses of the channel wall of the first sub-channel 301A and the channel wall of the second sub-channel 301B. The adjacent first sub-channels 301A and 302 include a second partition wall 802. Optionally, the thickness D2 of the second partition wall 802 can be understood as the sum of the thicknesses of the channel wall of the first sub-channel 301A and the channel wall of the second channel 302. In this embodiment, the thickness D1 of the first partition wall 801 is set to be less than the thickness D2 of the second partition wall 802. This makes the wall thickness between channels of the same color (both the first sub-channel 301A and the second sub-channel 301B belong to the first channel 301 and have the same color of color-producing particles) less than the wall thickness between channels of different colors (the first sub-channel 301A belongs to the first channel 301, and the first channel 301 and the second channel 302 have different color-producing particles). By increasing the thickness of the barrier between different color channels, it is possible to minimize color mixing between channels, which is beneficial to ensuring display quality.

[0100] In some alternative embodiments, please refer to Figure 24 , Figure 24 This is a schematic diagram of the planar structure of a display device provided in an embodiment of the present invention. The display device 111 provided in this embodiment includes the display panel 000 provided in any of the above embodiments of the present invention. The display device 111 provided in the embodiment of the present invention has the beneficial effects of the display panel 000 provided in the embodiment of the present invention. For details, please refer to the specific description of the display panel 000 in the above embodiments. This embodiment will not repeat the description here.

[0101] As can be seen from the above embodiments, the display panel and display device provided by the present invention achieve at least the following beneficial effects:

[0102] The display panel of the present invention can be an electrophoretic display device, comprising a first substrate and a second substrate disposed opposite to each other, with a plasma layer disposed between the first substrate and the second substrate. At least two independent first channels and second channels can be disposed in the plasma layer, and both the first channel and the second channel can be filled with plasma containing color-developing particles. In the present invention, the bending shape of the first channel and the second channel in the plasma layer is serpentine, without branching. The first channel includes at least an adjacent first sub-channel and a second sub-channel, and the first sub-channel and the second sub-channel are interconnected through a first connecting channel. The interconnected and adjacent first sub-channels and second sub-channels both extend along a first direction. When plasma containing color-developing particles is injected into the first channel, the plasma in the first sub-channel can flow smoothly and unobstructed into the second sub-channel adjacent to the first sub-channel after reaching the first connecting channel. Then, it continues to flow smoothly into the next set of first sub-channels, first connecting channels, and second sub-channels in sequence. Similarly, the shape of the second channel is designed according to the shape of the first channel, with the same bending situation. Therefore, the plasma in the second channel can also flow smoothly and unobstructed during injection. Ultimately, this ensures that the plasma fills the entire first and second channels, avoiding problems such as blockages or incomplete filling of dead corners caused by poor plasma flow. This improves the uniformity of plasma flow in its corresponding channels during injection, ensures the injection effect, and is beneficial to improving display quality.
