[0041] The features and exemplary embodiments of various aspects of the present application will be described below in detail, in order to make the purposes, technical solutions and advantages of the present application more clear and apparent, the present application will be further described in detail below in combination with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, but not to limit the present application. For those skilled in the art, the present application can be implemented without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by showing examples of the present application.

[0042] It should be noted that in this paper, relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations. Moreover, the terms "include", "contain" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or includes elements inherent to such process, method, article or equipment. Without more limitation, the elements defined by the statement "include" do not exclude the presence of other identical elements in the process, method, article or equipment including the elements.

[0043] The display panel has a display area and an encapsulation area, the encapsulation area is arranged around the display area, the display area is a region of the display panel for displaying images, the encapsulation area is located in a frame region of the display panel, and the encapsulation area surrounds the outside of the display area, which mainly isolates the light-emitting device of the display area from the external environment to prevent the invasion of moisture, harmful gas, dust and radiation and reduce external force damage, stabilizes various parameters of the device, and improves the service life.

[0044] With the development of display panels, narrow frames have become mainstream products in the market, but due to the limitation of the frame size, the corner area in the encapsulation area is close to the display area, and in the curing process of the encapsulation glue, the display area near the corner area is easily affected by the laser energy, which causes the local display area to be prone to light-emitting device burnout problems.

[0045] To solve the above problems, in a first aspect, please refer to Figures 1 to 3 The display panel provided in the embodiments of the present application has a display area AA and an encapsulation area B, the encapsulation area B is arranged at least partially around the display area AA, and the encapsulation area B includes a flat area B1 and a corner area B2 connecting adjacent flat areas B1. The display panel includes a first substrate 1 and a second substrate 2 arranged oppositely, and a first encapsulation glue 3 located between the first substrate 1 and the second substrate 2.

[0046] The first encapsulation glue 3 is arranged around the encapsulation area B, and the first encapsulation glue 3 has a first edge 31, a second edge 32 and a virtual center line 33 located at the central position of the first edge 31 and the second edge 32 in the width direction of the first encapsulation glue 3, the virtual center line 33 includes a first virtual straight line segment 331 located in the flat area B1 and a first virtual curved segment 332 located in the corner area B2; wherein the first virtual straight line segment 331 is located at four long sides of a first virtual rectangle 333 respectively, and the first virtual curved segment 332 is arranged outwardly protruding relative to the display area AA and at least partially located outside the first virtual rectangle 333.

[0047] The display panel provided in the embodiments of the present application includes but is not limited to a liquid crystal display panel or an organic light-emitting display panel, etc., which is not limited in the embodiments of the present application. When the display panel is a liquid crystal display panel, the first substrate 1 and the second substrate 2 are array substrate and color film substrate respectively; when the display panel is an organic light-emitting display panel, the first substrate 1 and the second substrate 2 are array substrate and cover plate respectively. The first encapsulation glue 3 is located in the encapsulation area B and arranged between the first substrate 1 and the second substrate 2, the first encapsulation glue 3 is used for bonding the first substrate 1 and the second substrate 2, and isolating the light-emitting device of the display area AA from the external environment to prevent the invasion of moisture and harmful gas.

[0048] The packaging area B includes four flat areas B1 and four corner areas B2 for connecting adjacent flat areas B1. The flat areas B1 and the corner areas B2 jointly enclose a ring structure and surround the outer periphery of the display area AA. The first encapsulation glue 3 is arranged in the packaging area B and mainly isolates the light emitting device of the display area AA from the external environment.

[0049] The first encapsulation glue 3 has a first edge 31 and a second edge 32 opposite in the width direction. One of the first edge 31 and the second edge 32 is relatively close to the display area AA, and the other is relatively far away from the display area AA. The virtual center line 33 is located at the central position of the first edge 31 and the second edge 32 in the width direction. In general, in order to ensure the bonding uniformity of the first encapsulation glue 3, the laser will solidify the first encapsulation glue 3 along the path of the virtual center line 33 during the solidification process of the first encapsulation glue 3.

[0050] In the embodiments of the present application, the first virtual curved segment 332 in the virtual center line 33 is outwardly protruding relative to the display area AA, so that at least part of the first virtual curved segment 332 is located outside the first virtual rectangle 333. The size of the first virtual rectangle 333 is determined by the first virtual straight line segment 331 of the virtual center line 33. The first virtual rectangle 333 is a closed rectangular structure, and the four long sides coincide with the four first virtual straight line segments 331.

[0051] Compared with the traditional display panel, the first virtual curved segment 332 in the display panel provided by the embodiments of the present application is outwardly protruding relative to the display area AA, that is, the distance between the first virtual curved segment 332 and the display area AA is farther. During the solidification process of the first encapsulation glue 3 in the corner area B2, the distance between the first virtual curved segment 332, that is, the laser action path, and the display area AA is increased, thereby reducing the influence of the laser energy on the display area AA near the corner area B2, reducing the possibility of burning the light emitting device, and improving the yield of the display panel.

[0052] It should be noted that in the embodiments of the present application, the first virtual curved segment 332 is outwardly protruding relative to the display area AA. The specific implementation method can be that one of the first edge 31 and the second edge 32 located in the corner area B2 is kept stationary, and the other is outwardly protruding relative to the display area AA, so that the first virtual curved segment 332 can protrude outwardly compared with the traditional display panel. Alternatively, both the first edge 31 and the second edge 32 located in the corner area B2 can be outwardly protruding relative to the display area AA, so as to further increase the protruding degree of the first virtual curved segment 332. The specific structure of the first encapsulation glue 3 can be adjusted and changed according to the actual needs of the display panel, and the embodiments of the present application do not limit this.

[0053] Please refer to Figure 4In some embodiments, the first edge 31 is located on a side of the second edge 32 away from the display area AA, and at least one of the first edge 31 and the second edge 32 comprises a second straight segment 311 located in the flat area B1 and a second curved segment 312 located in the corner area B2. The second straight segment 311 is located on four long sides of a second virtual rectangle 313 respectively, and the second curved segment 312 is arranged outwardly protruding relative to the display area AA and at least partially located outside the second virtual rectangle 313.

[0054] The first edge 31 and the second edge 32 are opposite edges of the encapsulation adhesive in the width direction. It can be understood that the width direction of the first encapsulation adhesive 3 changes according to different positions. Specifically, the width direction of the first encapsulation adhesive 3 located in the flat area B1 is parallel to the row direction or the column direction of the display panel, and the width direction of the first encapsulation adhesive 3 located in different positions in the corner area B2 changes with the change of the extension direction of the first encapsulation adhesive 3. Therefore, the width direction of the first encapsulation adhesive 3 needs to be determined according to the position.

[0055] In the embodiments of the present application, at least one of the first edge 31 and the second edge 32 comprises the second straight segment 311 and the second curved segment 312, the second curved segment 312 is arranged outwardly protruding relative to the display area AA and at least partially located outside the second virtual rectangle 313, the size of the second virtual rectangle 313 is determined by the second straight segment 311, the second virtual rectangle 313 is a closed rectangular structure and four long sides coincide with four second straight segments 311.

[0056] The present application arranges the second curved segment 312 outwardly protruding relative to the display area AA, so that the first virtual curved segment 332 is arranged outwardly protruding relative to the display area AA, thereby increasing the distance between the first virtual curved segment 332 and the display area AA, reducing the influence of the laser energy on the display area AA near the corner area B2, and improving the production yield.

[0057] Please refer to Figure 5 In some embodiments, the distance between the first edge 31 and the second edge 32 in the width direction located in the corner area B2 is always consistent.

[0058] As can be known from the foregoing, the embodiment of the present application increases the distance between the first virtual curved section 332 and the display area AA by outwardly protruding at least one of the first edge 31 and the second edge 32 in the corner area B2. Further, the embodiment of the present application outwardly protrudes both the first edge 31 and the second edge 32, while controlling the distance between the first edge 31 and the second edge 32 in the corner area B2 to be consistent in the width direction, i.e., the width of the first encapsulation adhesive 3 at the connection between the corner area B2 and the flat area B1 is the same as the width of the first encapsulation adhesive 3 at any position in the corner area B2, so as to ensure that the width of the first encapsulation adhesive 3 in the corner area B2 is the same as the width of the first encapsulation adhesive 3 in the flat area B1, and to ensure the consistency of the width of the first encapsulation adhesive 3, thereby improving the uniformity of adhesion of the display panel.

[0059] Referring to Figure 6 and Figure 7 In some embodiments, the display panel further includes a second encapsulation adhesive 4 disposed in the same layer as the first encapsulation adhesive 3, and the second encapsulation adhesive 4 is located between the corner area B2 and the display area AA in the width direction.

[0060] The second encapsulation adhesive 4 is disposed in the same layer as the first encapsulation adhesive 3, and the second encapsulation adhesive 4 is located on the side of the first encapsulation adhesive 3 close to the display area AA. When the first encapsulation adhesive 3 is cured, the second encapsulation adhesive 4 is mainly used to absorb part of the laser energy close to the display area AA, thereby reducing the risk of burning the light emitting device in the display area AA. Meanwhile, the second encapsulation adhesive 4 can also play a role in improving the encapsulation effect and reducing the risk of invasion of moisture and harmful gases.

[0061] It should be noted that the second encapsulation adhesive 4 has various arrangement forms, and can be similar to the first encapsulation adhesive 3 in structure, i.e., the second encapsulation adhesive 4 is also annular and surrounds the outer periphery of the display area AA; or the second encapsulation adhesive 4 can be arranged only in the corner area B2 to reduce the risk of burning the light emitting device in the display area AA near the corner area B2, and the present application does not limit this.

[0062] Referring to Figure 8 In some embodiments, the display panel further includes a signal line 5 disposed between the second encapsulation adhesive 4 and the first substrate 1, and the signal line 5 at least partially overlaps the second encapsulation adhesive 4 on the first substrate 1 in the orthographic projection.

[0063] Generally, the first encapsulation glue 3 is provided below a pad metal 6, and the pad metal 6 is used to reflect laser energy to improve the curing effect of the first encapsulation glue 3. In the embodiment of the present application, the second encapsulation glue 4 is added to absorb part of the laser energy. Meanwhile, the second encapsulation glue 4 at least partially overlaps the signal line 5 on the first substrate 1 in the orthographic projection, and the signal line 5 can play the same role as the pad metal 6 in reflecting part of the laser energy to improve the absorption efficiency of the second encapsulation glue 4 to the laser energy, wherein the signal line 5 includes but is not limited to a power line. Alternatively, the second encapsulation glue 4 at the orthographic projection of the first substrate 1 is located within the orthographic projection of the signal line 5 on the first substrate 1.

[0064] As shown in Figure 8 some embodiments, the display panel further includes a pad metal 6, and the pad metal 6 at least partially overlaps the first encapsulation glue 3 on the first substrate 1 in the orthographic projection, and the signal line 5 is provided in the same layer as the pad metal 6.

[0065] As can be known from the foregoing, the pad metal 6 is used to reflect laser energy to improve the curing effect of the first encapsulation glue 3, and the embodiment of the present application further provides the pad metal 6 in the same layer as the signal line 5, so that the pad metal 6 and the signal line 5 can share the same mask to be prepared, thereby reducing the number of masks and preparation procedures, and improving the production efficiency.

[0066] Please refer to Figure 9 In some embodiments, the second encapsulation glue 4 has a tendency to protrude in the direction close to the first virtual bending segment 332.

[0067] In the embodiment of the present application, at least part of the second encapsulation glue 4 is relatively close to the first virtual bending segment 332, which can improve the absorption efficiency of the second encapsulation glue 4 to the laser energy, thereby further reducing the risk of burnout of the light emitting device in the display area AA and improving the product yield.

[0068] Alternatively, the second encapsulation glue 4 at the orthographic projection of the first substrate 1 is located within the orthographic projection of the signal line on the first substrate, and the signal line located within the corner area B2 has a tendency to protrude outward. This design can improve the reflection effect of the signal line to the laser energy, and further improve the absorption capacity of the second encapsulation glue 4 to the laser energy.

[0069] As shown in Figure 9 some embodiments, the minimum distance L between the first virtual bending segment 332 and the second encapsulation glue 4 in the width direction is less than 500 μm.

[0070] During the curing process of the first encapsulant 3, the laser cures the first encapsulant 3 along the path of the virtual center line 33. The influence range of the laser is typically 500 μm. To ensure the absorption capacity of the second encapsulant 4 by the laser energy, this embodiment controls the minimum distance L between the first virtual bending segment 332 and the second encapsulant 4 in the width direction to be less than 500 μm, thereby ensuring that at least a portion of the second encapsulant 4 can absorb the laser energy. Optionally, the minimum distance between the first virtual bending segment 332 and the display area AA is greater than 500 μm, thereby significantly reducing the impact of laser energy on the display area AA.

[0071] It is understandable that the second encapsulating adhesive 4 itself has a certain width. Therefore, the minimum distance L between the first virtual bending segment 332 and the second encapsulating adhesive 4 in the width direction is the distance between the edge of the second encapsulating adhesive 4 on the side closer to the first virtual bending segment 332 in the width direction and the first virtual bending segment 332.

[0072] Secondly, please refer to Figure 10 This application also provides a display device, including the display panel of any of the foregoing embodiments. The embodiments shown in the figures only use a mobile phone as an example to illustrate the display device. It is understood that the display device provided in this application can be other display devices with display functions, such as computers, televisions, and in-vehicle display devices, and this application does not impose specific limitations on them.

[0073] Thirdly, please refer to Figure 11 As shown in Figure 12, this application embodiment provides a method for packaging a display panel. The display panel has a display area and a packaging area, with the packaging area at least partially surrounding the display area. The packaging area includes a flat area and a corner area connecting the flat area. The packaging method includes:

[0074] S100, providing a first substrate;

[0075] S110. An encapsulation material layer is formed on the first substrate. The encapsulation material layer is patterned to form a first encapsulating adhesive surrounding the encapsulation area. The first encapsulating adhesive has a first edge, a second edge, and a virtual center line located at the center of the first edge and the second edge in its width direction. The virtual center line includes a first virtual straight line segment located in the straight area and a first virtual curved segment located in the corner area. The first virtual straight line segment is located on the four long sides of the first virtual rectangle. The first virtual curved segment protrudes outward relative to the display area and is at least partially located outside the first virtual rectangle.

[0076] S120, The second substrate is disposed on the side of the encapsulation material layer away from the first substrate;

[0077] S130. The first encapsulating adhesive is cured along the virtual center line to cure the encapsulating material layer and form an encapsulating layer.

[0078] Referring to Figure 12a and Figure 12c In step S100 and step S120, the display panel provided by the embodiments of the present application can be a liquid crystal display panel, or an organic light emitting display panel or other types of display panel. When the display panel is a liquid crystal display panel, the first substrate 1 can be any one of an array substrate and a color film substrate, and the second substrate 2 is the other one of the array substrate and the color film substrate; when the display panel is an organic light emitting display panel, the first substrate 1 can be any one of an array substrate and a cover plate, and the second substrate 2 is any one of the array substrate and the cover plate, which is not limited by the embodiments of the present application.

[0079] Referring to Figure 12b In step S110, the encapsulation material layer is arranged on the first substrate 1, including the first encapsulation glue 3 formed in a pattern. The structure of the first encapsulation glue 3 can refer to the structure of the first encapsulation glue 3 in the foregoing embodiments, which will not be described again by the embodiments of the present application.

[0080] Referring to Figure 12d Wherein the dashed line indicated by the arrow is the laser path, i.e. the position of the virtual center line 33. In step S130, the laser is cured along the path of the virtual center line 33 to process the first encapsulation glue. Since the virtual center line 33 is located at the central position of the first edge and the second edge in the width direction, the curing treatment along the virtual center line 33 can ensure the bonding uniformity of the encapsulation glue on both sides, and improve the reliability of the display panel. Meanwhile, the first virtual curved segment 332 in the virtual center line 33 is arranged outwardly protruding relative to the display area AA, which can reduce the influence of laser energy on the display area AA, and improve the product yield.
