DETAILED DESCRIPTION

[0041] The embodiments of the present application are described below in conjunction with the drawings in the present application. It should be understood that the implementation methods described below in conjunction with the drawings are exemplary descriptions for explaining the technical solutions of the embodiments of the present application and do not constitute a limitation on the technical solutions of the embodiments of the present application.

[0042] Those skilled in the art will appreciate that, unless expressly stated otherwise, the singular forms "a", "an", "said" and "the" used herein may also include plural forms. It should be further understood that the term "comprising" used in the specification of the present application refers to the presence of the features, integers, steps, operations, elements and / or components, but does not exclude the implementation of other features, information, data, steps, operations, elements, components and / or combinations thereof supported by the technical field. The term "and / or" used herein refers to at least one of the items defined by the term, for example, "A and / or B" may be implemented as "A", or as "B", or as "A and B".

[0043] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0044] In the existing design scheme, the packaging-related designs of the conventional shape area (such as the four sides of the rectangular structure) and the special-shaped area (such as the four corners of the rectangular structure), such as the reflective layer design, are exactly the same. After analyzing the reliability issues, the fundamental reason for the failure of packaging in the special-shaped area is that the special-shaped area has an irregular shape and poor reflective ability, resulting in a reduction in the effective packaging area, a deterioration in the ability to resist water and oxygen erosion, and easy erosion by water vapor, causing the display product to fail.

[0045] The display panel and its manufacturing method, and the display device provided in the present application are intended to solve at least one of the above technical problems in the prior art.

[0046] The following is a detailed description of the technical solution of the present application and how the technical solution of the present application solves the above technical problems with specific embodiments. It should be noted that the following implementations can refer to, draw on or combine with each other, and the same terms, similar features and similar implementation steps in different implementations will not be described repeatedly.

[0047] It should be noted that in the embodiment of the present application, the porosity is the opening range, specifically refers to the ratio of the opening area to the total area. For example, the porosity of the transition portion 33 refers to the ratio of the total area of ​​the openings on the transition portion 33 to the total area of ​​the transition portion 33.

[0048] The embodiment of the present application provides a display panel. The structural diagram of the display panel 100 is shown in FIG. Figures 1 to 13As shown, it includes: a first substrate 10, a second substrate 20, a reflective layer 30 and an encapsulation layer 40, the first substrate 10 has a display area 11 and a non-display area 12 located around the display area 11; the second substrate 20 is arranged opposite to the first substrate 10; the reflective layer 30 is arranged on the side of the first substrate 10 facing the second substrate 20, the orthographic projection of the reflective layer 30 on the first substrate 10 is located in the non-display area 12, and the reflective layer 30 is provided with a via hole 31; the encapsulation layer 40 is located between the reflective layer 30 and the second substrate 20, the orthographic projection of the encapsulation layer 40 on the first substrate 10 is located in the non-display area 12 and at least covers the orthographic projection of the via hole 31 on the first substrate 10, and the encapsulation layer 40 is connected to the first substrate 10 through the via hole 31.

[0049] Among them, the reflective layer 30 includes a main body portion 32 and a transition portion 33 arranged along the circumference of the display area 11, two adjacent main body portions 32 are connected by the transition portion 33, and there is an angle α between the tangents of the outer contours of the positive projections of the two adjacent main body portions 32 on the first substrate 10; the opening rate of the transition portion 33 is smaller than the opening rate of the main body portion 32.

[0050] In the embodiment of the present application, the reflective layer 30 is disposed on the first substrate 10, and the first substrate 10 is used to support the reflective layer 30. The encapsulation layer 40 is disposed on the second substrate 20, and the second substrate 20 is used to support the encapsulation layer 40. The first substrate 10 and the second substrate 20 are arranged opposite to each other, and the reflective layer 30 and the encapsulation layer 40 are sequentially arranged between the first substrate 10 and the second substrate 20. The first substrate 10 has a display area 11 and a non-display area 12 located around the display area 11. The orthographic projections of the reflective layer 30 and the encapsulation layer 40 on the first substrate 10 are both located in the non-display area 12. The reflective layer 30 is provided with a via hole 31. The orthographic projection of the encapsulation layer 40 on the first substrate 10 at least covers the orthographic projection of the via hole 31 on the first substrate 10. The encapsulation layer 40 is connected to the first substrate 10 through the via hole 31 to connect the first substrate 10 and the second substrate 20 together.

[0051] In the embodiment of the present application, the reflective layer 30 includes a main body portion 32 and a transition portion 33, the main body portion 32 and the transition portion 33 are arranged along the circumference of the display area 11, two adjacent main bodies 32 are connected by the transition portion 33, and there is an angle α between the tangents of the outer contours of the positive projections of the two adjacent main bodies 32 on the first substrate 10. Therefore, the transition portion 33 corresponds to the angle α and is used to connect the two adjacent main bodies 32, so that one of the two adjacent main bodies 32 is transitionally connected to the other main body portion 32 through the transition portion 33, and the opening rate of the transition portion 33 is smaller than the opening rate of the main body portion 32, so that the reflection area of ​​the transition portion 33 per unit area is larger than the reflection area of ​​the main body portion 32, and the reflection ability of the transition portion 33 is improved. Therefore, through the technical solution of the present application, the reflected light intensity of the transition part 33 can be increased, thereby increasing the energy gathering force of the transition part 33, increasing the packaging width and strength corresponding to the transition part 33, improving the sintering energy and the effective packaging area, and improving the packaging reliability of the special-shaped area (i.e., the area corresponding to the transition part 33), which can reduce the reliability risk of the display product and improve the performance and competitiveness of the display product.

[0052] Alternatively, if Figure 4 As shown, in the embodiment of the present application, the angle α is greater than 0° and less than 180°.

[0053] In the embodiment of the present application, two adjacent main body portions 32 are connected by a transition portion 33, and there is an angle α between the tangents of the outer contours of the positive projections of the two adjacent main body portions 32 on the first substrate 10, and the transition portion 33 corresponds to the angle α. The angle α is greater than 0° and less than 180°, so there is a bending or curving area between the two adjacent main body portions 32 to achieve the connection between the two adjacent main body portions 32. The transition portion 33 is used to achieve a transitional connection between the two adjacent main body portions 32, so as to facilitate the transition from one main body portion 32 of the two adjacent main body portions 32 to the other main body portion 32.

[0054] Optionally, in the embodiment of the present application, the material of the encapsulation layer 40 is glass glue.

[0055] Alternatively, if Figure 4 As shown, in the embodiment of the present application, the reflective layer 30 is a rectangular frame structure, the four frames of the rectangular frame structure all form a main body 32, and the four corners of the rectangular frame structure all form transition portions 33. The four frames of the rectangular frame structure respectively form four main bodies 32, the four corners of the rectangular frame structure respectively form four transition portions 33, and two adjacent frames of the rectangular frame structure are connected by a corner, which corresponds to the position where the two adjacent frames intersect to form an angle.

[0056] In the prior art, the effective packaging width of the special-shaped area (such as the four corners of a rectangular structure) is narrower than that of the regular shape area (such as the four sides of a rectangular structure), and is easily corroded by water vapor, resulting in failure.

[0057] In view of the reliability problem of irregular areas in special-shaped display products, the embodiment of the present application proposes a design scheme for improving the packaging performance of special-shaped display products, optimizes the packaging position of irregular areas (such as the area corresponding to the transition part 33) in the special-shaped display products, and performs phased design of the reflective layer 30 for different areas, that is, the part of the reflective layer 30 corresponding to the conventional shape area (such as the four sides of the rectangular structure) (that is, the main body 32) can adopt a conventional design and remain unchanged with the design in the prior art, and the part of the reflective layer 30 corresponding to the special-shaped area (such as the four corners of the rectangular structure) (that is, the transition part 33) is changed in design, and the change direction is to reduce the opening area and increase the reflective area of ​​the reflective layer, so that the reflective ability of the special-shaped area is greater than that of the conventional shape area, thereby increasing the reflected light intensity of the special-shaped area in the sintering process, and increasing the energy concentration force of the special-shaped area during the laser sintering process, thereby increasing the packaging width and strength.

[0058] After the improvement, the effective packaging width of the special-shaped area is close to that of the regular shape area. Even by adjusting the reflective layer design, the effective packaging width of the special-shaped area can be made wider than that of the regular shape area, thereby increasing the sintering energy and effective packaging area, improving the packaging reliability and trustworthiness of the special-shaped area, and enhancing product competitiveness, so as to improve the reliability problem of irregular areas in special-shaped display products.

[0059] In special-shaped display products, the positions with the highest risk of poor reliability are all in the special-shaped areas (or irregular shapes). It should be noted that in the embodiments of the present application, the shape of the special-shaped area of ​​the display product is not limited, and the shape of the special-shaped area can be obtuse angle, acute angle, arc, trapezoid, arc segment, etc.

[0060] Optionally, in the embodiment of the present application, the material of the reflective layer 30 is metal.

[0061] Optionally, in the embodiment of the present application, the metal of the reflective layer can be provided on the same layer as the metal of the driving circuit layer on the first substrate 10, which can simplify the process.

[0062] In an optional embodiment of the present application, Figure 4 As shown, the via 31 includes a plurality of first through holes 321 and a plurality of second through holes 331, the first through holes 321 are arranged in the main body 32; the second through holes 331 are arranged in the transition portion 33, and the areas of the orthographic projections of the first through holes 321 and the second through holes 331 on the first substrate 10 are the same; the arrangement density of the second through holes 331 is less than the arrangement density of the first through holes 321.

[0063] In the embodiment of the present application, the areas of the orthographic projections of the first through holes 321 arranged in the main body 32 and the second through holes 331 arranged in the transition portion 33 on the first substrate 10 are the same. By setting the arrangement density of the second through holes 331 to be smaller than the arrangement density of the first through holes 321, the opening ratio of the transition portion 33 can be made smaller than the opening ratio of the main body 32, so that the reflection area of ​​the transition portion 33 per unit area is larger than the reflection area of ​​the main body 32, and the reflection ability of the transition portion 33 is improved, thereby increasing the reflected light intensity and energy concentration of the transition portion 33, increasing the packaging width and strength corresponding to the transition portion 33, improving the sintering energy and effective packaging area, improving the packaging reliability and trustworthiness of the special-shaped area (i.e., the area corresponding to the transition portion 33), and improving the performance and competitiveness of the display product.

[0064] Alternatively, if Figure 4 As shown, a plurality of first through holes 321 are arranged at intervals in the main body portion 32, and a plurality of second through holes 331 are arranged at intervals in the transition portion 33, so as to avoid interference.

[0065] In an optional embodiment of the present application, Figure 5 As shown, the via 31 includes a plurality of first through holes 321 and a plurality of second through holes 331, the first through holes 321 are arranged in the main body 32; the second through holes 331 are arranged in the transition portion 33, and the area of ​​the orthographic projection of the second through holes 331 on the first substrate 10 is smaller than the area of ​​the orthographic projection of the first through holes 321 on the first substrate 10; the setting density of the second through holes 331 is less than or equal to the setting density of the first through holes 321.

[0066] In the embodiment of the present application, the area of ​​the orthographic projection of the second through hole 331 arranged in the transition portion 33 on the first substrate 10 is smaller than the area of ​​the orthographic projection of the first through hole 321 arranged in the main body 32 on the first substrate 10. By setting the setting density of the second through holes 331 to be less than or equal to the setting density of the first through holes 321, the opening ratio of the transition portion 33 can be made smaller than the opening ratio of the main body 32, so that the reflection area of ​​the transition portion 33 per unit area is greater than the reflection area of ​​the main body 32, and the reflection ability of the transition portion 33 is improved, thereby increasing the reflected light intensity and energy concentration of the transition portion 33, increasing the packaging width and strength corresponding to the transition portion 33, improving the sintering energy and effective packaging area, improving the packaging reliability and trustworthiness of the special-shaped area (i.e., the area corresponding to the transition portion 33), and improving the performance and competitiveness of the display product.

[0067] Alternatively, if Figure 4 and Figure 5 As shown, in the embodiment of the present application, the orthographic projections of the second through hole 331 and the first through hole 321 on the first substrate 10 have the same shape. This arrangement facilitates processing and simplifies the manufacturing process and steps.

[0068] Of course, in an optional implementation of the present application, the shapes of the orthographic projections of the second through hole 331 and the first through hole 321 on the first substrate 10 may be different according to actual needs and conditions.

[0069] Optionally, in the embodiment of the present application, the shape of the orthographic projection of the plurality of second through holes 331 on the first substrate 10 includes at least one of a circle, a polygon, an ellipse, a strip, and other shapes.

[0070] Optionally, in the embodiment of the present application, the shape of the orthographic projection of the plurality of first through holes 321 on the first substrate 10 includes at least one of a circle, a polygon, an ellipse, a strip, and other shapes.

[0071] In an optional embodiment of the present application, Figures 6 to 8 As shown, the via 31 includes a plurality of first through holes 321, at least one second through hole 331 and at least one third through hole 332, the first through hole 321 is arranged in the main body 32; the second through hole 331 is arranged in the transition portion 33, and the area of ​​the orthographic projection of the second through hole 331 and the first through hole 321 on the first substrate 10 is the same; the third through hole 332 is arranged in the transition portion 33, and the area of ​​the orthographic projection of the third through hole 332 on the first substrate 10 is smaller than the area of ​​the orthographic projection of the first through hole 321 on the first substrate 10; the sum of the arrangement density of the second through holes 331 and the third through holes 332 is less than or equal to the arrangement density of the first through holes 321.

[0072] In the embodiment of the present application, the areas of the orthographic projections of the second through hole 331 arranged in the transition portion 33 and the first through hole 321 arranged in the main body 32 on the first substrate 10 are the same, and the area of ​​the orthographic projection of the third through hole 332 arranged in the transition portion 33 on the first substrate 10 is smaller than the area of ​​the orthographic projection of the first through hole 321 arranged in the main body 32 on the first substrate 10. By setting the sum of the arrangement density of the second through holes 331 and the third through holes 332 to be less than or equal to the arrangement density of the first through holes 321, the opening ratio of the transition portion 33 can be made smaller than the opening ratio of the main body 32, so that the reflection area of ​​the transition portion 33 per unit area is greater than the reflection area of ​​the main body 32, the reflection ability of the transition portion 33 is improved, and then the reflected light intensity and energy concentration force of the transition portion 33 can be increased, so that the packaging width and strength corresponding to the transition portion 33 are increased, the sintering energy and the effective packaging area are improved, the packaging reliability and trustworthiness of the special-shaped area (i.e., the area corresponding to the transition portion 33) are improved, and the performance and competitiveness of the display product are improved.

[0073] Alternatively, if Figures 6 to 8As shown, in the embodiment of the present application, the shapes of the orthographic projections of the third through hole 332 and the second through hole 331 on the first substrate 10 are the same, so as to facilitate processing and simplify the manufacturing process and steps.

[0074] Of course, in an optional implementation of the present application, the shapes of the orthographic projections of the third through hole 332 and the second through hole 331 on the first substrate 10 may be different according to actual needs and conditions.

[0075] Optionally, in the embodiment of the present application, the shape of the orthographic projection of the plurality of third through holes 332 on the first substrate 10 includes at least one of a circle, a polygon, an ellipse, a strip, and other shapes.

[0076] In a specific embodiment of the present application, Figure 7 As shown, the plurality of second through holes 331 and the plurality of third through holes 332 are alternately arranged in sequence along a preset direction. The plurality of second through holes 331 and the plurality of third through holes 332 are regularly arranged, which is convenient for processing, so that the encapsulation layer 40 can easily cover the second through holes 331 and the third through holes 332, and can make the opening and reflection of the transition part 33 more uniform.

[0077] In another specific embodiment of the present application, Figure 8 As shown, the plurality of second through holes 331 and the plurality of third through holes 332 are arranged alternately in sequence.

Since the area of ​​the orthographic projection of the third through hole 332 on the first substrate 10 is smaller than the area of ​​the orthographic projection of the second through hole 331 on the first substrate 10, the opening ratio of the central area of ​​the transition portion 33 is smaller than the opening ratio of the edge of the transition portion 33, so that the reflected light intensity and energy concentration force of the central area of ​​the transition portion 33 are greater, and the packaging glue corresponding to the central area of ​​the transition portion 33 has a better melting effect. The packaging glue gradually spreads from the area corresponding to the center of the transition portion 33 to the area corresponding to the edge of the transition portion 33. This arrangement helps to increase the packaging width and strength of the transition portion 33, and improve the packaging reliability and trustworthiness of the special-shaped area (i.e., the area corresponding to the transition portion 33).

[0105] In the embodiment of the present application, the reflective layer 30 is disposed on one side of the first substrate 10, and the first substrate 10 is used to support the reflective layer 30. The encapsulation layer 40 is disposed on one side of the second substrate 20, and the second substrate 20 is used to support the encapsulation layer 40. The first substrate 10 and the second substrate 20 are laminated, so that the first substrate 10 and the second substrate 20 are arranged opposite to each other, and the reflective layer 30 faces the second substrate 20, and the encapsulation layer 40 faces the first substrate 10. The first substrate 10 has a display area 11 and a non-display area 12 located around the display area 11. The orthographic projections of the reflective layer 30 and the encapsulation layer 40 on the first substrate 10 are both located in the non-display area 12.

[0110] The laminating process refers to laminating the first substrate 10 and the second substrate 20 together so that the reflective layer area of ​​the first substrate 10 corresponds to the glue-coated area of ​​the second substrate 20 (wherein the glue-coated area can be the same width as the reflective layer 30 or slightly different).

[0111] The laser sintering process is to melt the coated packaging glue under high-energy laser irradiation so as to adhere the first substrate 10 and the second substrate 20 to complete the packaging.

[0112] In the embodiment of the present application, during the laser sintering process, the laser is reflected by the reflective layer 30, and the laser energy is concentrated to melt the packaging glue, and then react with the substrate to achieve the purpose of adhesion. By increasing the area of ​​the reflective layer 30, the energy concentration of the reflected laser can be effectively improved, the width of the effective packaging area can be increased, and the packaging reliability can be increased.

The conventional shape area (such as the four sides of the rectangular structure) uses the conventional design, and the special-shaped area (such as the four corners of the rectangular structure) is changed. The change direction is to reduce the opening area and increase the reflective area of ​​the reflective layer. The reflective ability of the special-shaped area is greater than that of the regular shape area, which increases the reflected light intensity in the sintering process, increases the sintering energy and the effective packaging area, improves the packaging reliability of the special-shaped area, and enhances the product competitiveness.

In the embodiments of the present application, the compensation design scheme for the reflective layer is not limited. It can be compensation for changes in the overall size of the holes, compensation for the size of local holes, compensation for cross-arrangement of large and small holes, etc. As long as the scheme can achieve the difference in the reflective area of ​​the reflective layer in different areas, it is within the protection scope of the present application.

Therefore, through the technical solution of the present application, the reflected light intensity of the transition part can be increased, thereby increasing the energy gathering force of the transition part, increasing the packaging width and strength corresponding to the transition part, improving the sintering energy and effective packaging area, improving the packaging reliability of the special-shaped area, reducing the reliability risk of the display product, and improving the performance and competitiveness of the display product.
