Description

Technical Field

[0002] Electronic paper (E-paper) is a new type of display panel, a bistable display technology based on the electrophoresis principle. It has a wide range of uses and has superior properties such as ultra-low energy consumption, thin as paper, bendable and book-like clarity. It uses black and white, light and dark changes to express text and pictures, and the display effect is very similar to that of real paper books. At present, electronic paper display panels are widely used in electronic readers (e-books), electronic price tags, smart cards, watches, mobile phones, industrial instruments, meters, dynamic display billboards and media products. Electrophoretic display technology is one of the electronic display technologies with development potential because it combines the advantages of ordinary paper and electronic displays. Among them, plasma display technology has a high-definition and high-resolution display effect because the microstructure cannot be seen from the front, which reduces the number of layers. The existing plasma display panel is mainly composed of an array substrate, a filter formed above the array substrate, a transparent electrode layer and a cofferdam. The gap between the cofferdam structure and the transparent electrode layer provides a lateral flow path for the electronic ink, resulting in partial loss of ink and affecting the display effect.

[0003] Therefore, how to reduce the lateral flow of electronic ink and improve the overall compression resistance of the display panel has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0026] The descriptions of the following embodiments refer to the attached drawings, which are used to illustrate specific embodiments in which the present invention can be implemented. The directional terms mentioned in the present invention, such as [up], [down], [front], [rear], [left], [right], [inside], [outside], [side], etc., are only with reference to the directions of the attached drawings. Therefore, the directional terms used are for explaining and understanding the present invention, rather than for limiting the present invention. In the drawings, units with similar structures are denoted by the same reference numerals. In the drawings, for clear understanding and convenient description, the thicknesses of some layers and regions are exaggerated. That is, the sizes and thicknesses of each component shown in the drawings are arbitrarily shown, but the present invention is not limited thereto.

[0027] Please refer to Figures 1 to 3 , Figure 1 A schematic cross-sectional view of a display panel provided by an embodiment of the present invention, Figure 2 is Figure 1 A schematic plan view of an isolation structure in the middle, Figure 3 is Figure 2 A schematic cross-sectional view along the M-M' and N-N' directions in the middle. Referring to Figure 1 , the display panel 100 includes a first substrate 10 and a second substrate 20 which are oppositely arranged, and an isolation structure 30 and plasma particles 40 located between the first substrate 10 and the second substrate 20. Optionally, the first substrate 10 is an array substrate, and the second substrate 20 is a counter substrate.

[0028] The first substrate 10 may include a first substrate and a driving circuit layer and a first electrode provided on one side of the first substrate. The driving circuit layer includes transistors, data lines and gate scanning lines connected to the transistors. The transistors are also connected to the first electrode. The data lines and the gate scanning lines are insulated and cross to define a plurality of pixel regions, and the first electrode is arranged corresponding to the pixel regions.

[0029] The second substrate 20 includes a second substrate 21, a heightening structure 22 and a packaging structure 23 disposed on one side of the second substrate 21, that is, both the heightening structure 22 and the packaging structure 23 are located on the side of the second substrate 21 facing the first substrate 10. The packaging structure 23 is located on the side of the heightening structure 22 away from the second substrate 21, and the packaging structure 23 faces the first substrate 10. Optionally, the material of the second substrate 21 is the same as that of the first substrate, such as a glass substrate. Of course, the second substrate 20 further includes a second electrode, the second electrode is disposed facing the first substrate 10, and the second electrode is disposed on the entire surface, and the second electrode may be located between the heightening structure 22 and the packaging structure 23. The second electrode is a transparent conductive electrode, and the material of the second electrode includes indium tin oxide (ITO), etc.

[0030] The heightening structure 22 is disposed in alignment with the isolation structure 30, and at least a part of the packaging structure 23 is located between the heightening structure 22 and the isolation structure 30. Thus, by providing the heightening structure 22 and the packaging structure 23 disposed in alignment with the isolation structure 30 on the second substrate 20, the heightening structure 22 can fill the gap between the isolation structure 30 and the second substrate 20, improving the compressive resistance of the display panel 100, and the packaging structure 23 fills between the heightening structure 22 and the isolation structure 30, enabling the heightening structure and the isolation structure 30 to be tightly combined together, completely filling the gap between the isolation structure 30 and the second substrate 20, improving the sealing performance of the isolation cavity 301, so as to seal the plasma particles 40 in the corresponding isolation cavity 301, thereby preventing the lateral flow of the plasma particles 40, and improving the problem that the lateral flow of the existing electronic ink causes local ink loss and affects the display effect. Among them, the material of the isolation structure 30 is at least one of acrylic resin, epoxy, polyurethane, silica gel, etc. The packaging material of the packaging structure 23 is at least one of transparent adhesives such as acrylic resin, epoxy, polyurethane, silica gel, etc.

[0031] It should be noted that the elevation structure 22 is disposed between the isolation structure 30 and the second substrate 20. Although the gap between the isolation structure 30 and the second substrate 20 has been filled, since the plasma particles 40 are nano-scale particles, lateral flow may still occur between the elevation structure 22 and the isolation structure 30. For this reason, the present invention further provides a packaging structure 23 between the elevation structure 22 and the isolation structure 30. The packaging material of the packaging structure 23 is a glue material, and the glue material can fill in minute gaps, enabling the packaging structure 23 to tightly combine the elevation structure 22 and the isolation structure 30 together. For example, when forming the packaging structure 23, the packaging material can be first sprayed on the side of the elevation structure 22 away from the second substrate 21, then the second substrate 20 and the first substrate 10 are aligned and adhered, and the sprayed packaging material is cured to form the packaging structure 23 that tightly combines the elevation structure 22 and the isolation structure 30 together, so as to improve the bonding force between the elevation structure 22 and the isolation structure 30. Optionally, the material of the packaging structure 23 is the same as that of the isolation structure 30 to improve the bonding force between the packaging structure 23 and the isolation structure 30, thereby further improving the bonding force between the elevation structure 22 and the isolation structure 30, and further improving the sealing performance of the isolation cavity 301.

[0032] Specifically, referring to Figure 1 and Figure 2 , the isolation structure 30 is disposed on the first substrate 10 and located between the first substrate 10 and the second substrate 20. The isolation structure 30 includes a plurality of first isolation portions 31 spaced along a first direction X and a plurality of second isolation portions 32 spaced along a second direction Y. Two adjacent first isolation portions 31 and two adjacent second isolation portions 32 together enclose an isolation cavity 301. Optionally, the isolation structure 30 is disposed corresponding to the data lines and the gate scan lines. For example, the first isolation portions 31 are disposed corresponding to the data lines, and the second isolation portions 32 are disposed corresponding to the gate scan lines. The isolation cavity 301 is disposed corresponding to the pixel region, that is, the isolation cavity 301 is disposed corresponding to the first electrode, and the isolation cavity 301 exposes the first electrode.

[0033] The isolation structure 30 includes a lower end surface connected to the first substrate 10 and an upper end surface opposite to the lower end surface. The upper end surface faces the elevation structure 22. Herein, the lower end surface of the isolation structure 30 refers to the surface of the isolation structure 30 in contact with the first substrate 10, and the upper end surface of the isolation structure 30 is opposite to the lower end surface, which means the surface of the isolation structure 30 on the side away from the first substrate 10.

[0034] Optionally, referring to Figure 3 , the width TD1 of the upper end surface 312 of the first isolation part 31 is 4-8 μm (micrometers), the width BD1 of the lower end surface 311 of the first isolation part 31 is 8-12 μm, that is, the longitudinal cross-sectional shape of the first isolation part 31 is trapezoidal, and the width TD1 of the upper end surface 312 of the first isolation part 31 is smaller than the width BD1 of the lower end surface 311 of the first isolation part 31. The width TD2 of the upper end surface 322 of the second isolation part 32 is 4-8 μm, the width BD2 of the lower end surface 321 of the second isolation part 32 is 8-12 μm, that is, the longitudinal cross-sectional shape of the second isolation part 32 is trapezoidal, and the width TD1 of the upper end surface 322 of the second isolation part 32 is smaller than the width BD1 of the lower end surface 321 of the second isolation part 32. In the direction perpendicular to the first substrate 10, the height H1 range of the first isolation part is 3-20 μm, the height H2 range of the second isolation part is 3-20 μm, and the heights of the first isolation part 31 and the second isolation part 32 are equal.

[0035] Optionally, the first isolation part 31 and the second isolation part 32 are integrally arranged, that is, the first isolation part 31 and the second isolation part 32 are integrally formed. For example, a stamping, photolithography, spraying or other process can be used to form the isolation structure 30 including the first isolation part 31 and the second isolation part 32 on the first substrate 10. At this time, the respective dimensions of the first isolation part 31 and the second isolation part 32 are the same. For example, the width TD1 of the first isolation part 31 is equal to the width TD2 of the second isolation part 32, and the height H1 of the first isolation part 31 is equal to the height H2 of the second isolation part 32.

[0036] In the direction perpendicular to the display surface of the display panel 100, the heightening structure 22 overlaps with the isolation structure 30, and the outer contour of the heightening structure 22 exceeds the outer contour of the upper end surface of the isolation structure 30. In other words, the orthographic projection of the heightening structure 22 on the first substrate 10 covers the orthographic projection of the upper end surface of the isolation structure 30 on the first substrate 10 and exceeds the orthographic projection range of the upper end surface of the isolation structure 30, that is, the area of the surface of the heightening structure 22 on the side away from the second substrate 21 is larger than the area of the upper end surface of the isolation structure 30, so as to increase the contact area between the encapsulation structure 23 and the isolation structure 30 and improve the sealing effect of the encapsulation structure 23.

[0037] Referring to Figure 2 and Figure 4, the heightening structure 22 includes a first heightening portion 221 and a second heightening portion 222. The first heightening portion 221 is disposed corresponding to the first isolation portion 31, and the second heightening portion 222 is disposed corresponding to the second isolation portion 32. The heightening structure 22 includes a plurality of first heightening portions 221 spaced along the first direction X, and a plurality of second heightening portions 222 spaced along the second direction Y. Two adjacent first heightening portions 221 and two adjacent second heightening portions 222 together define a groove 202, and the groove 202 corresponds to the isolation cavity 301. In the first direction X, the width of the first heightening portion 221 is greater than the width of the upper end surface 312 of the first isolation portion 31; in the second direction Y, the width of the second heightening portion 222 is greater than the width of the upper end surface 322 of the second isolation portion 32. Optionally, the width of the first heightening portion 221 is 8-12 μm, and the width of the second heightening portion 222 is 8-12 μm.

[0038] In an embodiment, the second substrate 20 includes a patterned light-shielding layer facing the first substrate 10, and the light-shielding layer forms the heightening structure 22 on the second substrate 20. That is, the heightening structure 22 is obtained by disposing a light-shielding layer on the second substrate 21 and patterning the light-shielding layer. The light-shielding layer can shield the display panel 100. Therefore, using the patterned light-shielding layer to form the heightening structure 22 can, while achieving the cooperation with the encapsulation structure 23 to eliminate the gap between the isolation structure 30 and the second substrate 20 and sealing the plasma particles 40 in the corresponding isolation cavity 301 to prevent the lateral flow of the plasma particles 40, also improve the contrast of the display panel 100. The material of the light-shielding layer is a black matrix (BM). Among them, the plasma particles 40 include plasma black particles 41 and plasma white particles 42.

[0039] Optionally, continue to refer to Figure 1, the encapsulation structure 23 includes a first encapsulation part 231 and a second encapsulation part 232 which are connected to each other. The first encapsulation part 231 is disposed opposite to the first isolation part 31 and the second isolation part 32, the second encapsulation part 232 is disposed opposite to the isolation cavity 301, and the second encapsulation part 232 is also located between the plasma particles 40 and the second substrate 20. That is to say, the encapsulation structure 23 is provided as a whole surface, which can improve the overall sealing performance of the isolation cavity 301. For example, a packaging material can be provided on the side of the heightening structure 22 away from the second substrate 20 by using one of the processes such as inkjet printing, slot coating, knife coating, screen printing, etc. to form the encapsulation structure 23. The encapsulation structure 23 covers the heightening structure 22 and the groove 202. Specifically, the first encapsulation part 231 covers the heightening structure 22, and the second encapsulation part 232 covers the groove 202. In this way, the relative height of the second encapsulation part 232 with respect to the first substrate 10 is greater than the relative height of the first encapsulation part 231 with respect to the first substrate 10, so as to increase the volume of the isolation cavity 301 and prevent the second encapsulation part 232 from affecting the movement of the plasma particles 40 in the isolation cavity 301. In addition, in order to prevent the encapsulation structure 23 provided as a whole surface from affecting the light emission of the display panel 100, the encapsulation structure 23 is formed of a transparent glue material, such as at least one of transparent materials such as acrylic resin, epoxy, polyurethane, silicone, etc.

[0040] In one embodiment, the display panel 100 further includes a sealing structure 50. The sealing structure 50 surrounds the isolation structure 30 and is used to isolate water and oxygen to prevent water and oxygen from entering the display panel 100. Optionally, the material of the sealing structure 50 includes one of acrylic resin, epoxy, polyurethane, silicone, etc.

[0041] In one embodiment, referring to Figures 1 to 5 , Figure 5 is another cross-sectional structure schematic diagram of the display panel provided by the embodiment of the present invention. Different from the above embodiment, the second substrate 20 includes a color filter layer 24. The color filter layer 24 includes color filter blocks corresponding to the isolation cavity 301. The colors of two adjacent color filter blocks are different, and two adjacent color filter blocks have an overlapping part at the position corresponding to the isolation structure 30, and the overlapping part forms the heightening structure 22.

[0042] Specifically, referring to Figure 5, the second substrate 20 includes a second substrate 21, a color filter layer 24, and an encapsulation structure 23 disposed on a side of the second substrate 21 facing the first substrate 10. The encapsulation structure 23 is located on a side of the color filter layer 24 away from the second substrate 21. The color filter layer 24 includes a plurality of color filter blocks of different colors, and the color filter blocks of different colors are formed by color resists of different colors. Among them, adjacent color filter blocks are spliced with each other, and adjacent color filter blocks have different colors. For example, the color filter layer 24 includes a red color filter block 241, a green color filter block 242, and a blue color filter block 243. The adjacent red color filter block 241 and the green color filter block 242 are spliced with each other, and the adjacent green color filter block 242 and the blue color filter block 243 are spliced with each other. The red color filter block 241, the green color filter block 242, and the blue color filter block 243 are all disposed corresponding to the isolation cavity 301 to achieve color display of the display panel 100.

[0043] Further, the position where two adjacent color filter blocks are spliced with each other corresponds to the isolation structure 30, and two adjacent color filter blocks are overlapped at the splicing position. For example, among two adjacent color filter blocks, an edge portion of one color filter block is overlapped on a surface of the other color filter block away from the second substrate 21, so that there is an overlapping portion at the splicing position of two adjacent color filter blocks, and the overlapping portion corresponds to the isolation structure 30. Optionally, the overlapping portion can be formed by controlling the overlap size, the fluidity of the color resist, and the thickness of the color resist film of the color filter block, so that the overlapping regions formed by splicing have the same height. Among them, the overlapping portion forms the heightening structure 22, that is, the heightening structure 22 is formed by setting an overlapping portion at the splicing position of two color filter blocks. In this way, while cooperating with the encapsulation structure 23 to eliminate the gap between the isolation structure 30 and the second substrate 20, sealing the plasma particles 40 in the corresponding isolation cavity 301 and preventing the lateral flow of the plasma particles 40, the color display of the display panel 100 can also be achieved.

[0044] Optionally, the second substrate 20 further includes a patterned light-shielding layer 25 located on a side of the color filter layer 24 away from the first substrate 10. The light-shielding layer 25 is disposed corresponding to the overlapping portion. The light-shielding layer 25 further includes an opening disposed corresponding to the isolation cavity 301, and the color filter block is disposed in the opening. The light-shielding layer 25 can shield light of the display panel 100 to improve the contrast of the display panel 100; at the same time, setting the light-shielding layer 25 can also reduce the difficulty of forming the overlapping portion of the color filter layer 24, making it easier to form a larger-height overlapping portion between adjacent color filter blocks. The material of the light-shielding layer 25 is a black matrix (BM).

[0045] Furthermore, the second substrate 20 further includes a second electrode 26 which is disposed over the entire surface and on the side of the color filter layer 24 away from the second substrate 21. The encapsulation structure 23 is disposed on the side of the second electrode 26 away from the second substrate 21. For other descriptions, please refer to the above embodiments and will not be elaborated herein.

[0046] Based on the same inventive concept, the present invention further provides a display device, which includes the display panel 100 described in any one of the foregoing embodiments. The display device includes electronic display devices such as e-readers, electronic price tags, smart cards, watches, mobile phones, industrial instruments, meters, and dynamic display billboards.

[0047] As can be seen from the above embodiments:

[0048] In a display panel and a display device provided by the present invention, the display panel includes a first substrate and a second substrate disposed opposite to each other, and an isolation structure and plasma particles located between the first substrate and the second substrate. The isolation structure is disposed on the first substrate and includes a plurality of first isolation portions spaced along a first direction and a plurality of second isolation portions spaced along a second direction. Two adjacent first isolation portions and two adjacent second isolation portions together define an isolation cavity. The plasma particles are disposed in the isolation cavity. A heightening structure and an encapsulation structure are disposed on the side of the second substrate facing the first substrate. The heightening structure is disposed in alignment with the isolation structure, and the encapsulation structure is located between the heightening structure and the isolation structure. In this way, by providing a heightening structure and an encapsulation structure corresponding to the isolation structure on the second substrate, the gap between the isolation structure and the second substrate is eliminated, the compressive resistance of the display panel is improved, and the plasma particles are sealed in the corresponding isolation cavity, thereby preventing the lateral flow of the plasma particles and improving the problem that the lateral flow of the existing electronic ink causes local ink loss and affects the display effect.
