例如，在图2所示的第一基板11中，所述第一基板11的上下两对边即涂覆相同的、胶宽沿封框胶13的涂覆的延伸方向，由中间向两端逐渐减小或增加的封框胶13，另两对边则涂覆有相同的均匀胶宽结构的封框胶13，本发明实施例对此不作赘述。For example, in the first substrate 11 shown in FIG. 2 , the upper and lower sides of the first substrate 11 are coated with the same glue width along the extending direction of the sealing glue 13, from the middle to both ends. The frame sealing glue 13 gradually decreases or increases, and the other two pairs of sides are coated with the same uniform glue width structure of the sealing glue 13 , which will not be described in this embodiment of the present invention.
另外需要说明的是，可采用常规制作工艺在所述第一基板或所述第二基板的另两对边涂覆相同的具备均匀胶宽结构的封框胶，本发明实施例对此也不作赘述。In addition, it should be noted that the same sealant with a uniform glue width structure can be coated on the other two opposite sides of the first substrate or the second substrate by using a conventional manufacturing process, and this embodiment of the present invention does not make any repeat.
步骤A2：将所述第一基板和所述第二基板进行粘合，得到粘合后的基板，并对粘合后的基板的四周边缘处的封框胶进行相同固化条件的封框胶固化操作，得到张力满足设定条件的封框胶，其中，所述固化条件可包括固化时间和/或温度。Step A2: bonding the first substrate and the second substrate to obtain a bonded substrate, and curing the sealant at the edges of the bonded substrate with the same curing conditions operation to obtain a frame sealant whose tension meets a set condition, wherein the curing condition may include curing time and/or temperature.
其中，所述封框胶固化操作可包括：UV固化操作和/或热固化操作。Wherein, the curing operation of the sealant may include: UV curing operation and/or thermal curing operation.
也就是说，在第一种方式中，可通过调整胶宽，使显示面板某两对边的封框胶内部产生张力，进而得到张力满足设定条件的封框胶。需要说明的是，该张力满足设定条件的封框胶内部产生的张力作用于粘合后的基板上时，可使得粘合后的基板的任两对边的封框胶的张力，沿封框胶的涂覆的延伸方向，由中间向两端逐渐减小或增加，进而使得基板弯曲，得到相应的弯曲显示面板。That is to say, in the first method, tension can be generated inside the sealant on two opposite sides of the display panel by adjusting the width of the glue, so as to obtain a sealant whose tension meets the set conditions. It should be noted that when the tension generated inside the sealant whose tension meets the set conditions acts on the bonded substrate, the tension of the sealant on any two opposite sides of the bonded substrate can be The extending direction of the coating of the sealant gradually decreases or increases from the middle to both ends, so that the substrate is bent, and a corresponding curved display panel is obtained.
第二种，包括以下步骤：The second method includes the following steps:
步骤B1：在所述第一基板或所述第二基板的任两对边涂覆添加有设定添加剂的封框胶，其中，所述任两对边的封框胶中的所述设定添加剂的含量沿封框胶的涂覆的延伸方向，由中间向两端逐渐减少或增多；另外两对边均匀涂覆未添加有设定添加剂的封框胶。Step B1: coating any two pairs of sides of the first substrate or the second substrate with a sealant added with setting additives, wherein the setting in the sealants of any two pairs of sides The content of the additive gradually decreases or increases from the middle to both ends along the extending direction of the coating of the sealant; the other two opposite sides are evenly coated with the sealant without the specified additive.
其中，所述添加剂可包括偶联剂和/或碳纤维，当然也可包括其它添加剂，本发明实施例对此不作限定。Wherein, the additive may include a coupling agent and/or carbon fiber, and of course may also include other additives, which are not limited in this embodiment of the present invention.
另外，以将封框胶13涂覆在第一基板11的表面边缘为例，在按照步骤B1进行封框胶的涂覆时，所得到的涂覆有相应封框胶的第一基板11的结构示意图可如图3所示，其中，所述第一基板11的上下两对边均匀涂覆有添加有设定添加剂的封框胶13、且所述设定添加剂的含量沿封框胶13的涂覆的延伸方向，由中间向两端逐渐减少，如添加有偶联剂的封框胶13，另两对边均匀涂覆未添加有设定添加剂的封框胶13，本发明实施例对此不作赘述。In addition, taking the coating of the frame sealant 13 on the surface edge of the first substrate 11 as an example, when the frame sealant is coated according to step B1, the obtained first substrate 11 coated with the corresponding frame sealant The schematic diagram of the structure can be shown in Figure 3, wherein the upper and lower sides of the first substrate 11 are evenly coated with a frame sealant 13 added with a set additive, and the content of the set additive is along the line of the sealant 13. The extension direction of the coating gradually decreases from the middle to both ends, such as the frame sealant 13 added with a coupling agent, and the other two opposite sides are uniformly coated with the frame sealant 13 without added additives, the embodiment of the present invention I won't go into details on this.
步骤B2：将所述第一基板和所述第二基板进行粘合，得到粘合后的基板，并对粘合后的基板的四周边缘处的封框胶进行相同固化条件的封框胶固化操作，得到张力满足设定条件的封框胶，其中，所述固化条件可包括固化时间和/或温度。Step B2: bonding the first substrate and the second substrate to obtain a bonded substrate, and curing the sealant at the edges of the bonded substrate with the same curing conditions operation to obtain a frame sealant whose tension meets a set condition, wherein the curing condition may include curing time and/or temperature.
也就是说，在第二种方式中，可通过在封框胶内添加添加剂，使显示面板的某两对边的封框胶内部产生张力，进而得到张力满足设定条件的封框胶。需要说明的是，该张力满足设定条件的封框胶内部产生的张力作用于粘合后的基板上时，可使得粘合后的基板的任两对边的封框胶的张力，沿封框胶的涂覆的延伸方向，由中间向两端逐渐减小或增加，进而使得基板弯曲，得到相应的弯曲显示面板。That is to say, in the second method, by adding additives in the frame sealant, tension can be generated inside the frame sealant on two opposite sides of the display panel, so as to obtain a frame sealant whose tension meets the set conditions. It should be noted that when the tension generated inside the sealant whose tension meets the set conditions acts on the bonded substrate, the tension of the sealant on any two opposite sides of the bonded substrate can be The extending direction of the coating of the sealant gradually decreases or increases from the middle to both ends, so that the substrate is bent, and a corresponding curved display panel is obtained.
第三种，包括以下步骤：The third method includes the following steps:
步骤C1：在所述第一基板或所述第二基板的四周涂覆相同的具备均匀胶宽结构的封框胶。Step C1: Coating the same sealant with uniform glue width around the first substrate or the second substrate.
其中，可采用常规制作工艺在所述第一基板或所述第二基板的四周涂覆相同的具备均匀胶宽结构的封框胶，本发明实施例对此不作赘述。Wherein, the same frame-sealing glue with a uniform glue width structure can be coated on the periphery of the first substrate or the second substrate using a conventional manufacturing process, which will not be described in this embodiment of the present invention.
步骤C2：对所述第一基板和所述第二基板进行粘合，得到粘合后的基板；Step C2: bonding the first substrate and the second substrate to obtain a bonded substrate;
步骤C3：对粘合后的基板的任两对边的封框胶，执行沿封框胶的涂覆的延伸方向、由中间向两端固化时间和/或温度逐渐减小的封框胶固化操作，或执行沿封框胶的涂覆的延伸方向、由中间向两端固化时间和/或温度逐渐增大的封框胶固化操作，另两对边的封框胶进行相同固化条件的封框胶固化操作，得到张力满足设定条件的封框胶。Step C3: For the sealant on any two opposite sides of the bonded substrate, execute the curing of the sealant along the extension direction of the sealant coating, from the middle to both ends, with the curing time and/or temperature gradually decreasing operation, or carry out the sealant curing operation along the extension direction of the sealant coating, from the middle to both ends, the curing time and/or temperature of the sealant gradually increases, and the sealants on the other two pairs of sides are sealed under the same curing conditions. The frame glue is cured to obtain a frame sealant whose tension meets the set conditions.
例如，如图4所示，以对粘合后的基板41的上下两对边的封框胶13，执行沿封框胶13的涂覆的延伸方向、由中间向两端固化条件逐渐增大的封框胶固化操作为例，可选的，可对粘合后的基板41的上下两对边的封框胶13利用沿封框胶13的涂覆的延伸方向、由中间向两端温度逐渐增加的加热条42进行热固化操作，对另两对边的封框胶13则按照常规工艺采用具备均匀温度的加热条进行热固化操作，从而使得所述基板41的上下两对边的封框胶13内部产生张力，张力满足设定条件的封框胶13。For example, as shown in FIG. 4 , with the sealants 13 on the upper and lower sides of the bonded substrate 41, the curing conditions gradually increase from the middle to both ends along the extension direction of the sealant 13 coating. The curing operation of the sealing glue is taken as an example. Optionally, the sealing glue 13 on the upper and lower sides of the bonded substrate 41 can be used along the extending direction of the coating of the sealing glue 13, from the middle to both ends. The gradually increasing heating strips 42 are thermally cured, and the other two opposite sides of the frame sealant 13 are thermally cured by using a heating strip with a uniform temperature according to the conventional process, so that the upper and lower two opposite sides of the substrate 41 are sealed Tension is generated inside the frame glue 13, and the frame sealant 13 whose tension meets the set conditions.
需要说明的是，在图4中，可以阴影的深浅代表加热条42的温度的高低，如，当阴影较深时，可认为其对应的温度较高，当阴影较浅时，可认为其对应的温度较低，本发明实施例对此不作赘述。It should be noted that, in FIG. 4, the depth of the shadow can represent the temperature of the heating strip 42. For example, when the shadow is darker, it can be considered that the corresponding temperature is higher; when the shadow is lighter, it can be considered that it corresponds to The temperature is relatively low, which will not be described in this embodiment of the present invention.
也就是说，在第三种方式中，可通过对粘合后的基板的任两对边的封框胶，执行沿封框胶的涂覆的延伸方向、由中间向两端固化条件逐渐减小的封框胶固化操作，或执行沿封框胶的涂覆的延伸方向、由中间向两端固化条件逐渐增大的封框胶固化操作，使得显示面板某两对边的封框胶的内部产生张力，进而得到张力满足设定条件的封框胶。需要说明的是，该张力满足设定条件的封框胶内部产生的张力作用于粘合后的基板上时，可使得基板弯曲，得到相应的弯曲显示面板。That is to say, in the third way, the sealing glue on any two opposite sides of the bonded substrate can be carried out along the extending direction of the coating of the sealing glue, and the curing conditions are gradually reduced from the middle to both ends. A small sealant curing operation, or perform a sealant curing operation in which the curing conditions gradually increase from the middle to both ends along the extension direction of the sealant coating, so that the sealant on two opposite sides of the display panel Tension is generated inside, and then the sealing glue with tension meeting the set conditions is obtained. It should be noted that when the tension generated inside the frame sealant whose tension meets the set conditions acts on the bonded substrate, the substrate can be bent to obtain a corresponding curved display panel.
需要说明的是，上述三种方式可结合使用，如，将第一种方式和第二种方式结合使用以制作张力满足设定条件的封框胶，或，将第三种方式和第二种方式结合使用以制作张力满足设定条件的封框胶等等，本发明实施例对此不作限定。It should be noted that the above three methods can be used in combination, for example, the first method and the second method can be used in combination to make a sealant whose tension meets the set conditions, or the third method and the second method can be combined. The method is used in combination to make a frame sealant whose tension meets the set conditions, etc., which is not limited in this embodiment of the present invention.

本发明实施例提供了一种显示面板及其制作方法、以及显示装置，由于所述显示面板的任两对边的封框胶的张力是沿封框胶的涂覆的延伸方向，由中间向两端逐渐减小或增加的，因此可使得所述显示面板具有弯曲度，相较于现有技术中采用树脂衬底或是采用贴服薄膜等方式制作的具有弯曲度的显示面板来说，本发明实施例所述显示面板的工艺流程较为简便、降低了制作成本。Embodiments of the present invention provide a display panel, a manufacturing method thereof, and a display device. Since the tension of the sealant on any two opposite sides of the display panel is along the extension direction of the sealant coating, from the middle to the The two ends are gradually reduced or increased, so that the display panel can have curvature. Compared with the display panel with curvature made of resin substrate or adhesive film in the prior art, The process flow of the display panel described in the embodiment of the present invention is relatively simple, and the manufacturing cost is reduced.
