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] Organic light-emitting diode (OLED) display panels are widely used in the field of display technology due to their many advantages, such as active light emission, high contrast, no viewing angle limitation, and the ability to achieve flexible display.

[0003] Currently, to improve the water and oxygen resistance of the OLED devices in flexible OLED display panels, encapsulating adhesives are typically used to encapsulate the display panel. In addition, display panels also require electrostatic discharge (ESD) protection. These numerous requirements make the structural design of the non-display areas of the display panel quite challenging. Summary of the Invention

[0004] This invention provides a display panel and a display device to improve the packaging reliability and anti-static capability of the display panel, and to reduce the width of the non-display area of ​​the display panel.

[0005] In a first aspect, embodiments of the present invention provide a display panel including a non-display area; The display panel also includes: First substrate; The encapsulating adhesive is located at least partially in the non-display area, and the encapsulating adhesive is located on one side of the first substrate; The reflective portion is located between the encapsulant and the first substrate in a direction perpendicular to the plane of the first substrate, and the encapsulant and the reflective portion at least partially overlap. The electrostatic discharge protection section is located on the side of the reflective section near the edge of the display panel, in a direction parallel to the plane of the first substrate. The electrostatic discharge protection section includes at least two spaced subsections, which are connected to the reflective section.

[0006] In one alternative implementation, the extension direction of the sub-part intersects the extension direction of the edge adjacent to the sub-part in the display panel.

[0007] In another alternative embodiment, the acute angle between the extension direction of the sub-part and the extension direction of the edge adjacent to the sub-part in the display panel is α, where α > 45°.

[0008] In another alternative embodiment, at least two sub-sections are arranged along a first direction parallel to the extension direction of the edge adjacent to the sub-section in the display panel.

[0009] In another alternative embodiment, the encapsulating adhesive and the electrostatic discharge protection portion at least partially overlap in a direction perpendicular to the plane of the first substrate.

[0010] In another alternative embodiment, the electrostatic protection portion at least partially surrounds the reflective portion.

[0011] In another alternative implementation, the distance between two adjacent sub-parts is greater than the width of the sub-parts.

[0012] In another alternative embodiment, the distance between two adjacent sub-parts is d1, where 0.1mm≤d1≤5mm.

[0013] In another alternative implementation, the width of the sub-part is less than or equal to 10 μm.

[0014] In another alternative embodiment, the shape of the orthographic projection of the sub-part onto the plane of the first substrate includes a straight line, a broken line, or a curve.

[0015] In another alternative implementation, at least two adjacent sub-parts are connected.

[0016] In another alternative implementation, the shortest distance between the encapsulating adhesive and the edge of the adjacent display panel is greater than or equal to 300 μm.

[0017] In another alternative embodiment, the display panel further includes a first insulating layer, at least a portion of which is located between two adjacent sub-sections.

[0018] In another alternative embodiment, the display panel further includes a second insulating layer located between the reflective portion and the first substrate.

[0019] In another alternative embodiment, the encapsulating adhesive includes glass melt adhesive.

[0020] In another alternative embodiment, the reflective portion and the electrostatic protection portion are formed in the same process.

[0021] Secondly, embodiments of the present invention provide a display device, including the display panel described above.

[0022] The display panel and display device provided in this embodiment of the invention, by providing an electrostatic discharge protection part in the non-display area of ​​the display panel and setting the electrostatic discharge protection part to include at least two sub-parts, can promptly conduct away static electricity entering the interior of the display panel from the edge of the display panel, avoiding the accumulation of static electricity inside the display panel that could burn other structures, such as encapsulating adhesive, thereby improving the electrostatic reliability of the display panel.

[0023] Furthermore, by spacing adjacent sub-sections apart, the present invention allows the cutting line to pass through multiple sub-sections and the hollowed-out sections between them when cutting the display motherboard. The hollowed-out sections avoid making the electrostatic protection section a large, monolithic structure, reducing the difficulty of cutting the electrostatic protection section with cutting tools such as blades. In other words, using the arrangement provided by the present invention, the area containing the sub-sections can be reused as a cutting area for cutting the display motherboard, eliminating the need for a separate cutting area in the non-display area. That is, the arrangement provided by the present invention improves the space utilization of the non-display area, facilitating a reduction in the width of the non-display area and enabling a narrow bezel design for the display panel.

Detailed Implementation

[0026] To better understand the technical solution of the present invention, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” as used in the embodiments of this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0029] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0030] As described in the background section, the design of the non-display area of ​​a display panel currently requires consideration of multiple factors, making it quite challenging. In implementing the embodiments of this invention, the inventors discovered that display panels have various requirements, including improved packaging reliability, enhanced drop resistance, better anti-static properties, and narrow bezels. Therefore, the structural design in the non-display area presents certain difficulties, and multiple effects cannot be simultaneously achieved.

[0031] like Figure 1 As shown, Figure 1 This is a cross-sectional schematic diagram of a display panel in the non-display area according to related technologies. The display panel includes a first substrate 1', an encapsulating adhesive 2', a reflective portion 3', and a second substrate 6'. The encapsulating adhesive 2' is used to bond the first substrate 1' and the second substrate 2', and the reflective portion 3' is used to improve the melting efficiency of the encapsulating adhesive 2' during the encapsulation process. In this display panel, after static electricity 7' enters the display panel, the portion of the reflective portion 3' extending beyond the encapsulating adhesive 2' can conduct static electricity; that is, the extended portion can be reused as an electrostatic discharge (ESD) protection portion. However, in this case, to ensure that the reflective portion 3' has a portion extending beyond the encapsulating adhesive 2', the width of the encapsulating adhesive 2' needs to be reduced. Reducing the width of the encapsulating adhesive 2' will decrease the drop resistance of the display panel. Drop resistance refers to the ability of the display panel to withstand drops from a height without damage. In particular, with the design trend of narrow-bezel display panels, the problem of reduced drop resistance caused by the shortened encapsulating adhesive 2' will become more prominent.

[0032] like Figure 2 As shown, Figure 2 This is a cross-sectional schematic diagram of another display panel in the related technology in the non-display area, in which the encapsulating adhesive 2' extends beyond the reflective part 3'. Based on this design, during electrostatic discharge (ESD) testing of the display panel, the encapsulating adhesive 2' will receive the conductive static electricity 7' before the reflective part 3', and in some cases, the static electricity 7' will even directly strike the encapsulating adhesive 2', causing the encapsulating adhesive 2' to burn, or even causing the encapsulating adhesive 2' to detach from the display panel, resulting in display panel failure.

[0033] Furthermore, in the manufacturing process of display panels, a large display master board is usually made first. After the various film layers in the display master board are prepared, the display master board is cut to obtain a display panel with a smaller area. For example... Figure 3 As shown, Figure 3 This is a schematic diagram of a display motherboard provided in an embodiment of the present invention, wherein six display panels 100 in the display motherboard 01 are used as examples. The display motherboard 01 includes a cutting area CA, and when the display motherboard 01 is cut, the cutting line is located within the cutting area CA. To ensure cutting accuracy, the edge area of ​​the display panel formed after cutting usually retains a preset cutting area CA. Figure 1 and Figure 2 As shown, the cutting area CA is located on the side of the non-display area NA closest to the edge E of the display panel. The setting of the cutting area CA also prevents the width of the non-display area NA of the display panel from being excessively compressed, thus limiting the realization of a narrow bezel for the display panel.

[0034] In view of this, embodiments of the present invention provide a display panel, such as... Figure 4 As shown, Figure 4 This is a schematic diagram of a display panel provided in an embodiment of the present invention. The display panel includes a non-display area NA. (In conjunction with...) Figure 4 , Figure 5 and Figure 6 As shown, Figure 5 This is an enlarged schematic diagram of the non-display area of ​​a display panel provided in an embodiment of the present invention. Figure 6 for Figure 5 Along a cross-sectional view of BB', the display panel further includes a first substrate 1, encapsulating adhesive 2, a reflective portion 3, and an electrostatic discharge protection portion 4. Among these, The encapsulating adhesive 2 is at least partially located in the non-display area NA, and is situated on one side of the first substrate 1; exemplaryly, the encapsulating adhesive 2 includes glass frit. The encapsulating adhesive 2 is used to encapsulate the display panel, preventing water, oxygen, and other substances from the external environment from penetrating the interior of the display panel and improving the encapsulation reliability of the display panel.

[0035] For example, such as Figure 1 As shown, the display panel also includes a display area AA. The display area AA includes multiple sub-pixels ( Figure 1 (Not shown). The encapsulating adhesive 2 described above can be used to protect sub-pixels from corrosion by water, oxygen, etc. in the external environment, thereby improving the reliability of the display panel and extending its service life.

[0036] like Figure 3 As shown, along the direction h1 perpendicular to the plane where the first substrate 1 is located, the reflective part 3 is located between the encapsulating adhesive 2 and the first substrate 1, and the encapsulating adhesive 2 and the reflective part 3 at least partially overlap.

[0037] Optional, such as Figure 6 As shown, the display panel also includes a second substrate 6, with the encapsulating adhesive 2 located between the first substrate 1 and the second substrate 6. When encapsulating the display panel with the encapsulating adhesive 2, the adhesive material is typically first applied to the frame of the display panel, and then irradiated with a laser to melt the adhesive at high temperature, thus bonding the first substrate 1 and the second substrate 6. The reflective part 3 can reflect the incident laser light onto the encapsulating adhesive 2, accelerating the melting rate of the adhesive 2 and improving the utilization rate of the laser.

[0038] For example, such as Figure 5 and Figure 6As shown, the display panel also includes an electrostatic discharge (ESD) protection section 4, which is located on the side of the reflective section 3 near the edge E of the display panel, parallel to the plane of the first substrate 1. The ESD protection section 4 can conduct away static electricity entering the interior of the display panel from its edge, improving the ESD reliability of the display panel. For example, during an ESD test of the display panel, the ESD protection section 4 can receive static electricity 7 entering from the edge E of the display panel and conduct it away promptly, preventing static electricity from accumulating inside the display panel and improving the ESD protection performance of the display panel.

[0039] In embodiments of the present invention, such as Figure 2 As shown, the electrostatic discharge (ESD) protection unit 4 includes at least two spaced-apart sub-units 40, which are connected to the reflective unit 3. During ESD testing of the display panel, multiple sub-units 40 can jointly receive and transmit static electricity. The sub-units 40 can conduct the static electricity out of the display panel through the reflective unit 3, preventing static electricity from accumulating inside the display panel. Optionally, the reflective unit 3 can be grounded.

[0040] For example, such as Figure 2 As shown, the electrostatic protection part 4 also includes a cutout part 41, which is located between two adjacent sub-parts 40 that are spaced apart.

[0041] The display panel provided in this embodiment of the invention, by providing an electrostatic discharge protection part 4 in the display panel and setting the electrostatic discharge protection part 4 to include at least two sub-parts 40, can promptly conduct away static electricity entering the interior of the display panel from the edge E of the display panel, avoiding the problem of static electricity accumulating inside the display panel and burning other structures, such as the encapsulating adhesive 2, thereby improving the electrostatic reliability of the display panel.

[0042] Furthermore, by arranging adjacent sub-sections 40 at intervals, the cutting line can pass through multiple sub-sections 40 and the cutout portion 41 located between adjacent sub-sections 40 during the cutting of the display motherboard. The cutout portion 41 avoids making the electrostatic protection portion 4 a large, monolithic structure, reducing the difficulty of cutting the display motherboard including the electrostatic protection portion 4 using cutting tools such as blades. This also allows the area where the sub-sections 40 are located to be reused as a cutting area for cutting the display motherboard, eliminating the need for a separate cutting area in the non-display area NA. In other words, the arrangement provided by this embodiment improves the space utilization of the non-display area, helps reduce the width of the non-display area NA, and enables a narrow bezel design for the display panel.

[0043] Furthermore, by employing the configuration provided in this embodiment of the invention, static electricity can be transferred using the electrostatic protection unit 4, eliminating the need to shorten the width of the encapsulating adhesive 2 and ensuring its area, thereby improving the display panel's drop resistance. Moreover, this configuration also avoids excessively increasing the width of the encapsulating adhesive 2. For example, a certain distance can be maintained between the encapsulating adhesive 2 and the edge E of the display panel, preventing static electricity 7 from directly striking the encapsulating adhesive 2 and avoiding electrostatic burns. This helps ensure the encapsulation reliability and display effect of the display panel.

[0044] For example, such as Figure 5 and Figure 6 As shown, along direction h1 perpendicular to the plane of the first substrate 1, the encapsulating adhesive 2 and the electrostatic discharge protection part 4 at least partially overlap. This arrangement increases the area of ​​the encapsulating adhesive 2, which helps improve the display panel's drop resistance.

[0045] It should be noted that, in Figure 5 In order to more clearly distinguish between the reflective part 3 and the encapsulating adhesive 2, the upper and lower boundaries of the two are shown to be misaligned. In the actual structure of the display panel, the boundaries of the two can coincide.

[0046] Optional, such as Figure 5 and Figure 6 As shown, the shortest distance between the encapsulating adhesive 2 and the edge E of the adjacent display panel is d2, where d2 ≥ 300 μm. This arrangement increases the distance between the encapsulating adhesive 2 and the edge E of the adjacent display panel, preventing direct electrostatic discharge (ESD) from striking the encapsulating adhesive 2 during ESD testing, reducing the likelihood of ESD damage to the encapsulating adhesive 2, and improving the encapsulation reliability of the display panel.

[0047] For example, such as Figure 7 As shown, Figure 7 This is a cross-sectional schematic diagram of another display panel provided in an embodiment of the present invention. The non-display area NA further includes a driving signal line 51 and peripheral circuitry 52. ​​Exemplarily, the driving signal line 51 includes a first power signal line PVEE and a connection trace RE, with the connection trace RE electrically connected to the first power signal line PVEE. Exemplarily, the connection trace RE can be connected to the anode of the light-emitting element in the display area AA. Figure 7 (Not shown) Same layer setting.

[0048] Optionally, the peripheral circuit 52 includes a shift register circuit VSR, which can provide control signals to the sub-pixels in the display area AA.

[0049] like Figure 7As shown, the display panel also includes a planarization layer 53, a pixel definition layer 54, and an electrode layer 55, with the electrode layer 55 located on the side of the pixel definition layer 54 away from the first substrate 1. For example, the electrode layer 55 can serve as the cathode of a light-emitting element in the display area AA.

[0050] For example, in an embodiment of the present invention, the extending direction of the sub-part 40 intersects the extending direction of the edge E adjacent to the sub-part 40 in the display panel.

[0051] Combination Figure 3 As shown, when cutting the display motherboard 01, the movement trajectory of the cutting tool is parallel to the edge of the display panel 100 formed by the cut. In this embodiment of the invention, by setting the sub-part 40 to intersect with the edge E, when the area where the sub-part 40 is located is reused for cutting, the situation where the movement trajectory of the cutting tool, i.e., the cutting line is exactly along the extension direction of the sub-part 40, can be avoided, thereby reducing the contact area between the cutting tool and the sub-part 40. Since the sub-part 40 is usually made of metal, if the cutting tool directly contacts a large area of ​​metal, the cutting difficulty is relatively large. In this embodiment of the invention, by making the extension direction of the sub-part 40 intersect with the extension direction of the edge E adjacent to the sub-part 40 in the display panel, it is equivalent to making the extension direction of the sub-part 40 intersect with the extension direction of the cutting line, which can reduce the cutting difficulty of the display motherboard 01 and help improve the process yield.

[0052] In this embodiment of the invention, the angle between the extending direction of the sub-part 40 and the extending direction of the edge E adjacent to the sub-part 40 in the display panel is α. For example, as shown... Figure 5 As shown, in this embodiment of the invention, α can be set to 90°. That is, the extending direction of the sub-part 40 and the extending direction of the edge E adjacent to the sub-part 40 in the display panel are perpendicular to each other.

[0053] Or, such as Figure 8 As shown, Figure 8 This is a schematic diagram of another reflective part and electrostatic protection part provided in an embodiment of the present invention. In this embodiment of the present invention, α can also be an acute angle.

[0054] When α is an acute angle, for example, in this embodiment of the invention, α can be set to > 45°. Based on this setting, when dealing with, for example... Figure 3 During the process of cutting the display motherboard 01 shown to form a display panel, when the area where the sub-part 40 is located is reused as a cutting area, the contact area between the cutting tool and the sub-part 40 can be reduced, thereby reducing the cutting difficulty of the display motherboard 01.

[0055] For example, such as Figure 5 and Figure 8As shown, at least two sub-sections 40 are arranged along a first direction h21, which is parallel to the extension direction of the edge E adjacent to the sub-section 40 in the display panel. With this arrangement, when cutting the display motherboard using a cutting tool, the movement trajectory of the cutting tool can pass through the alternately arranged sub-sections 40 and the cutout portion 41. This reduces the contact area between the cutting line and the sub-section 40, preventing the cutting line from moving exactly along the extension direction of a single sub-section 40 through a complete sub-section 40, thus reducing the difficulty of cutting.

[0056] Optional, such as Figure 9 As shown, Figure 9 This is a schematic diagram illustrating the distribution of an electrostatic discharge (ESD) protection section and a reflective section in a display panel according to an embodiment of the present invention. The ESD protection section 4 at least partially surrounds the reflective section 3. The reflective section 3 at least partially surrounds the display area AA. This arrangement allows the ESD protection section 4 to protect as many areas as possible within the display panel, thereby improving the ESD protection capability of the display panel.

[0057] Optional, such as Figure 5 and Figure 8 As shown, the distance between two adjacent sub-parts 40 is d1, and the width of the sub-part 40 is W, where d1 > W. This arrangement increases the distance between two adjacent sub-parts 40. When cutting the display motherboard with a cutting tool, the contact area between the cutting tool and the electrostatic protection part 4 can be reduced, facilitating cutting.

[0058] Optionally, 0.1mm ≤ d1 ≤ 5mm. This setting avoids excessively small spacing between adjacent sub-sections 40, reducing the manufacturing difficulty of the sub-sections 40. On the other hand, it also avoids excessively large spacing between adjacent sub-sections 40, which would result in too few sub-sections 40 around the display area and affect electrostatic conduction.

[0059] For example, the sub-section 40 can be fabricated using a process of first forming a film and then patterning it. Optionally, the patterning process includes photolithography.

[0060] For example, the reflective portion 3 and the electrostatic discharge protection portion 4 can be formed in the same process. They can be made of the same material to reduce the number of manufacturing steps in the display panel. For example, their materials include conductors, such as metals.

[0061] In another alternative embodiment, the reflective part 3 and the electrostatic protection part 4 may be made of different materials. Optionally, they may also be formed in different processes.

[0062] For example, the display panel further includes an array film layer, which includes structures such as wiring and thin-film transistors. The fabrication of at least one of the sub-parts 40 and the reflective part 3 can be performed in the same process as at least a portion of the array film layer, thereby simplifying the fabrication process of the display panel.

[0063] Optionally, the width W of the sub-section 40 can be on the order of micrometers. For example, W ≤ 10 μm. By keeping W ≤ 10 μm when the cutting line passes through the sub-section 40, this embodiment of the invention can reduce the difficulty of cutting.

[0064] For example, the shape of the sub-part 40 in the orthographic projection onto the plane of the first substrate 1 includes a straight line, a broken line, or a curve. Figure 5 , Figure 8 and Figure 9 The shape of the sub-part 40 as an orthographic projection onto the plane of the first substrate 1 includes straight lines as an illustration.

[0065] Or, such as Figure 10 As shown, Figure 10 This is a schematic diagram of another reflective part and electrostatic protection part provided in an embodiment of the present invention, wherein the shape of the sub-part 40 in the orthographic projection of the plane on which the first substrate 1 is located includes a broken line as an illustration.

[0066] In another alternative implementation, such as Figure 11 and Figure 12 As shown, Figure 11 and Figure 12 The diagram shows two other types of reflective parts and electrostatic protection parts provided in the embodiments of the present invention, wherein the shape of the sub-part 40 includes a curve as an illustration. Figure 11 The curve corresponding to subsection 40 has an inflection point as an illustration. Figure 12 The curve corresponding to sub-section 40 has two inflection points as an illustration. Of course, the shape of sub-section 40 can also be set to other curve shapes, and this embodiment of the invention does not limit this.

[0067] For example, such as Figure 5 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, in this embodiment of the invention, two adjacent sub-parts 40 can be made unconnected.

[0068] In another alternative implementation, such as Figure 13 and Figure 14 As shown, Figure 13 and Figure 14This diagram illustrates two other types of reflective and electrostatic discharge (ESD) protection components provided in embodiments of the present invention. In these embodiments, at least two adjacent sub-components 40 can also be connected. This arrangement accelerates the conduction of static electricity within the sub-components 40, allowing static electricity to be conducted away from the display panel more quickly, thus improving the ESD protection capability of the display panel.

[0069] Optional, such as Figure 13 As shown, in this embodiment of the invention, multiple sub-sections 40 can be connected end-to-end sequentially to achieve... Figure 13 Taking the orientation shown as an example, for the sub-part 40 located in the middle, one end can be connected to the sub-part 40 located above and adjacent to it, and the other end can be connected to the sub-part 40 located below and adjacent to it.

[0070] Or, such as Figure 14 As shown, in embodiments of the present invention, at least two adjacent sub-parts 40 can be grouped together, different groups are not connected to each other, and two adjacent sub-parts 40 within the same group are electrically connected. Figure 14 The diagram illustrates two adjacent sub-parts 40 within the same group.

[0071] Or, such as Figure 15 As shown, Figure 15 This is a schematic diagram of another reflective part and electrostatic protection part provided in an embodiment of the present invention. In this embodiment of the present invention, the middle parts of two adjacent sub-parts 40, excluding the ends, can also be electrically connected. Figure 15 The diagram illustrates two adjacent sub-parts 40 that intersect and connect in the middle to form an "X" shape.

[0072] It should be noted that when two adjacent sub-sections 40 are electrically connected, the shape of the sub-section 40 can be any of the following: a straight line, a broken line, or a curve. Figure 13 , Figure 14 and Figure 15 The straight line shape of sub-part 40 is for illustrative purposes only.

[0073] For example, such as Figure 16 As shown, Figure 16 for Figure 5 A cross-sectional view along CC' shows that the display panel also includes a first insulating layer 81, at least a portion of which is located between two adjacent sub-sections 40.

[0074] The provision of the first insulating layer 81 can make the upper surface of the film layer where the sub-part 40 is located flatter. When using a cutting tool, such as a cutting wheel, to cut the display motherboard and reuse the area where the sub-part 40 is located as the cutting area, the flatness of the film layer contacted by the cutting tool can be improved, which is more conducive to the cutting of the display motherboard.

[0075] Optionally, the first insulating layer 81 may include an inorganic insulating layer. For example, the first insulating layer 81 may include silicon nitride, silicon oxide, silicon oxynitride, etc.

[0076] For example, when manufacturing a display panel, sub-parts 40 spaced apart can be formed on the surface of the first substrate 1 first, and then the cutouts 41 between two adjacent sub-parts 40 can be filled with an insulating material.

[0077] Optionally, in embodiments of the present invention, the thickness of the first insulating layer 81 can be equal to the thickness of the sub-part 40, so that the surface of the first insulating layer 81 away from the substrate and the surface of the sub-part 40 away from the substrate are coplanar. With this arrangement, when the display motherboard is cut using a cutting tool, the cutting tool can fall on the plane jointly defined by the first insulating layer 81 and the sub-part 40. The thickness directions of both the first insulating layer 81 and the sub-part 40 are perpendicular to the plane containing the first substrate 1.

[0078] Optional, such as Figure 17 As shown, Figure 17 for Figure 5 In another cross-sectional view along CC', the display panel further includes a second insulating layer 82. Along a direction h1 perpendicular to the plane of the first substrate 1, the second insulating layer 82 is located between the electrostatic protection portion 4 and the first substrate 1. The provision of the second insulating layer 82 can increase the adhesion between the electrostatic protection portion 4 and the first substrate 1, and also increase the reflective portion (…). Figure 17 The adhesion between the electrostatic discharge protection part 4 (not shown) and the first substrate 1 is reduced, which reduces the possibility of the electrostatic discharge protection part 4 and the reflective part 3 falling off the surface of the first substrate 1, thereby improving the packaging reliability and electrostatic discharge protection capability of the display panel.

[0079] For example, in making a product with such Figure 17 When constructing a display panel with the structure shown, a second insulating layer 82 can be formed first on the surface of the first substrate 1, and then a reflective portion can be formed on the surface of the second insulating layer 82. Figure 17 (Not shown) and sub-section 40. Then, encapsulating adhesive is formed on the side of the reflective portion away from the first substrate 1.

[0080] This invention also provides a display device, such as... Figure 18 As shown, Figure 18 This is a schematic diagram of a display device provided in an embodiment of the present invention. The display device includes the display panel 100 described above. The specific structure of the display panel 100 has been described in detail in the above embodiments and will not be repeated here. Of course, Figure 18 The display device shown is for illustrative purposes only. The display device can be any electronic device with display function, such as a mobile phone, tablet computer, laptop computer, e-reader or television.

[0081] The display device provided in this embodiment of the invention includes an electrostatic discharge protection part 4 in the display panel 100, and the electrostatic discharge protection part 4 is configured to include at least two sub-parts 40. This can promptly conduct away static electricity that enters the interior of the display panel from the edge of the display panel, preventing static electricity from accumulating inside the display panel and burning other structures, such as the encapsulating adhesive 2, thereby improving the electrostatic reliability of the display panel.

[0082] Furthermore, by arranging adjacent sub-sections 40 at intervals, the cutting line can pass through multiple sub-sections 40 and the cutout portion 41 located between adjacent sub-sections 40 during the cutting of the display motherboard. The cutout portion 41 avoids making the electrostatic protection portion 4 a large, monolithic structure, reducing the difficulty of cutting the display motherboard including the electrostatic protection portion 4 using cutting tools such as blades. This also allows the area where the sub-sections 40 are located to be reused as a cutting area for cutting the display motherboard, eliminating the need for a separate cutting area in the non-display area NA. In other words, the arrangement provided by this embodiment improves the space utilization of the non-display area, helps reduce the width of the non-display area NA, and enables a narrow bezel design for the display panel.

[0083] Furthermore, by employing the configuration provided in this embodiment of the invention, static electricity can be transferred using the electrostatic protection unit 4, eliminating the need to shorten the width of the encapsulating adhesive 2 and ensuring its area, thereby improving the display panel's drop resistance. Moreover, this configuration also avoids excessively increasing the width of the encapsulating adhesive 2. For example, a certain distance can be maintained between the encapsulating adhesive 2 and the edge E of the display panel, preventing static electricity 7 from directly striking the encapsulating adhesive 2 and avoiding electrostatic burns. This helps ensure the encapsulation reliability and display effect of the display panel.

[0084] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
