鉴于此，本发明实施例提供了一种显示装置及制作方法，用于降低显示装置中部分膜层发生变形甚至崩开的风险，提高显示装置的良率。In view of this, embodiments of the present invention provide a display device and a manufacturing method, which are used to reduce the risk of deformation or even collapse of some film layers in the display device, and improve the yield of the display device.

如图2所示为本发明实施例提供的一种显示装置的结构示意图，具体来讲，该显示装置包括：FIG. 2 is a schematic structural diagram of a display device according to an embodiment of the present invention. Specifically, the display device includes:

显示面板10，显示面板10包括平板部101、弯折部102和固定部103，其中，弯折部102位于平板部101和固定部103之间，固定部103通过弯折部102弯折至平板部101的背面；Thedisplay panel 10 includes aflat plate part 101 , abending part 102 and afixing part 103 , wherein thebending part 102 is located between theflat plate part 101 and thefixing part 103 , and thefixing part 103 is bent to the flat plate through thebending part 102 the back ofpart 101;

在具体实施过程中，平板部101用于画面显示，固定部103用于绑定驱动芯片。In the specific implementation process, theflat plate part 101 is used for screen display, and thefixing part 103 is used for binding the driving chip.

设置在平板部101背面的第一支撑膜20，设置在固定部103面向平板部101一侧的第二支撑膜30；Thefirst support film 20 disposed on the back of theflat plate portion 101, and thesecond support film 30 disposed on the side of thefixing portion 103 facing theflat plate portion 101;

在具体实施过程中，第一支撑膜20和第二支撑膜30均包括基底及涂布在该基底上胶材，其中，基底通常为高分子材料，通过第一支撑膜20和第二支撑膜30对显示面板10进行了有效的支撑保护，避免了在显示装置的后续工艺中对显示面板10的损伤。在具体实施过程中，第一支撑膜20和第二支撑膜30中可以是同种基底和胶材所制成的背膜，还可以是不同胶材所制成的背膜，在此不做限定。In a specific implementation process, both thefirst support film 20 and thesecond support film 30 include a base and a glue material coated on the base, wherein the base is usually a polymer material, and thefirst support film 20 and the second support film pass through thefirst support film 20 and the second support film. 30 effectively supports and protects thedisplay panel 10 to avoid damage to thedisplay panel 10 in the subsequent process of the display device. In the specific implementation process, thefirst support film 20 and thesecond support film 30 may be back films made of the same substrate and adhesive material, or may be back films made of different adhesive materials, which will not be described here. limited.

设置在所述弯折部102内侧的固定胶40，且所述固定胶40位于所述第一支撑膜20和所述第二支撑膜30之间。Thefixing glue 40 is disposed on the inner side of thebending portion 102 , and thefixing glue 40 is located between the first supportingfilm 20 and the second supportingfilm 30 .

在具体实施过程中，设置在弯折部102内侧的固定胶40，还位于第一支撑膜20和第二支撑膜30之间，不仅保证了平板部101与弯折部102间的平缓过渡，还保证了弯折部102与固定部103间的平缓过渡，从而对来自弯折部102的应力进行有效的分散，避免了显示面板10的弯折部102因应力集中所致的走线断裂，保证了显示装置的良率。本发明人在实际研究中发现在设置固定胶40前后，弯折部102的边缘应力分布的示意图分别如图3和图4所示，其中，图3为图1中弯折部012内侧未设置固定胶时其边缘应力的其中一种分布示意图，图3中虚线框区域C1和C2为应力分布区域。图4为图2中弯折部102内侧设置固定胶40时其边缘应力的其中一种分布示意图，图4中虚线框区域D1和D2为应力分布区域。图4相较于图3而言，应力分布更为分散，相应地对显示面板10的作用力更小，从而避免了弯折部102边缘因应力集中所致的走线断裂。In the specific implementation process, thefixing glue 40 disposed on the inner side of thebending portion 102 is also located between the first supportingfilm 20 and the second supportingfilm 30, which not only ensures a smooth transition between theflat plate portion 101 and thebending portion 102, It also ensures a smooth transition between thebending part 102 and thefixing part 103, so as to effectively disperse the stress from thebending part 102, and avoid the line breakage of thebending part 102 of thedisplay panel 10 caused by stress concentration, The yield rate of the display device is guaranteed. The inventors found in the actual research that before and after the fixingglue 40 is installed, the schematic diagrams of the edge stress distribution of the bendingportion 102 are shown in FIG. 3 and FIG. 4 respectively. One of the distribution diagrams of the edge stress when the glue is fixed. The dotted frame regions C1 and C2 in FIG. 3 are the stress distribution regions. FIG. 4 is a schematic diagram of one of the edge stress distributions when the fixingglue 40 is disposed inside the bendingportion 102 in FIG. 2 . The dotted frame regions D1 and D2 in FIG. 4 are stress distribution regions. Compared with FIG. 3 , the stress distribution in FIG. 4 is more dispersed, and accordingly, the acting force on thedisplay panel 10 is smaller, thereby avoiding the breakage of the traces caused by the stress concentration at the edge of the bendingportion 102 .

在具体实施过程中，由于设置在弯折部102内侧的固定胶40，还会对弯折部102施加与回弹力方向相反的粘结力，从而削弱了显示面板10的弯折部102因弯折所产生的回弹力，进而降低显示装置中部分膜层发生变形甚至崩开的风险，提高了显示装置的良率。In the specific implementation process, due to the fixingglue 40 disposed on the inner side of the bendingportion 102, a bonding force opposite to the direction of the resilience force is also applied to the bendingportion 102, thereby weakening the bendingportion 102 of thedisplay panel 10 due to bending The rebound force generated by the folding is reduced, thereby reducing the risk of deformation or even collapse of some film layers in the display device, and improving the yield of the display device.

在本发明实施例中，固定胶40的弹性模量范围为20Mpa～100Mpa，比如，固定胶40的弹性模量为41Mpa。在具体实施过程中，选择较高弹性模量的固定胶40，相应地，固定胶40越柔软，对弯折部102弯折所产生的回弹力的削弱效果越好，从而降低了显示装置中部分膜层发生变形甚至崩开的风险。In the embodiment of the present invention, the elastic modulus of the fixingglue 40 ranges from 20 Mpa to 100 Mpa, for example, the elastic modulus of the fixingglue 40 is 41 Mpa. In the specific implementation process, the fixingglue 40 with a higher elastic modulus is selected. Correspondingly, the softer the fixingglue 40 is, the better the weakening effect of the rebound force generated by the bending of the bendingportion 102 is, thereby reducing the number of times in the display device. Risk of deformation or even collapse of part of the film layer.

在本发明实施例中，固定胶40包括聚碳酸酯、聚丙烯酸中的至少一种。在具体实施过程中，本领域技术人员可以根据实际应用中对弯折部102所产生回弹力的削弱效果来选择相应材料的固定胶40，在此不做限定。In the embodiment of the present invention, the fixingglue 40 includes at least one of polycarbonate and polyacrylic acid. In the specific implementation process, those skilled in the art can select the fixingglue 40 of the corresponding material according to the weakening effect of the resilient force generated by the bendingportion 102 in practical applications, which is not limited herein.

在本发明实施例中，如图5所示为显示装置的其中一种结构示意图，具体来讲，固定胶40包括靠近第一支撑膜20的第一端401，和靠近第二支撑膜30的第二端402，第一端401与第二端402贴合接触。如图6所示为显示装置中的弯折部102未弯折前的其中一种结构示意图。图5为图6中弯折部102弯折后的结构示意图。在具体实施过程中，由于在弯折部102弯折后，固定胶40的第一端401和第二端402贴合接触，此时，由于固定胶40的第一端401和第二端402贴合接触从而产生了与回弹力方向相反的力F’。如图5所示为固定部103与弯折部102相接的位置为受力点，弯折部102因弯折所产生的回弹力为F，因固定胶40两端贴合接触所产生的力F’，与回弹力F方向相反，从而削弱了回弹力F对显示装置可操作区AA内的膜层的应力作用，降低了显示装置中部分膜层发生变形甚至崩开的风险。In the embodiment of the present invention, FIG. 5 is a schematic diagram of one of the structures of the display device. Specifically, the fixingglue 40 includes afirst end 401 close to thefirst support film 20 , and afirst end 401 close to thesecond support film 30 . For thesecond end 402 , thefirst end 401 is in contact with thesecond end 402 . FIG. 6 is a schematic diagram of one of the structures of the bendingportion 102 in the display device before being bent. FIG. 5 is a schematic structural diagram of the bendingportion 102 in FIG. 6 after being bent. In the specific implementation process, after the bendingportion 102 is bent, thefirst end 401 and thesecond end 402 of the fixingglue 40 are in contact with each other. The snug contact thus creates a force F' in the opposite direction of the rebound force. As shown in FIG. 5 , the position where the fixingportion 103 and the bendingportion 102 are in contact is the point of force, and the resilient force generated by the bendingportion 102 due to bending is F. The force F' is opposite to the rebound force F, thereby weakening the stress effect of the rebound force F on the film layer in the operable area AA of the display device, and reducing the risk of deformation or even collapse of part of the film layer in the display device.

在具体实施过程中，固定胶40的第一端401可以与第一支撑膜20接触，如图2所示，还可以是与第一支撑膜20间隔第一预设距离，如图5所示，其中，该第一预设距离可以是实际工艺误差所导致的距离，还可以是根据实际应用需要所设定的距离，在此不做限定。固定胶40的第二端402可以与第二支撑膜30接触，还可以是与第二支撑膜30间隔第二预设距离，该第二预设距离可以是实际工艺误差所导致的距离，还可以是根据实际应用需要所设定的距离，在此不做限定。In a specific implementation process, thefirst end 401 of the fixingglue 40 can be in contact with the first supportingfilm 20 , as shown in FIG. 2 , or can be separated from the first supportingfilm 20 by a first preset distance, as shown in FIG. 5 , wherein the first preset distance may be a distance caused by an actual process error, or may be a distance set according to actual application requirements, which is not limited herein. Thesecond end 402 of the fixingglue 40 may be in contact with thesecond support film 30, and may also be spaced apart from thesecond support film 30 by a second preset distance, and the second preset distance may be a distance caused by an actual process error, or It may be a distance set according to actual application requirements, which is not limited here.

在本发明实施例中，固定胶40填充弯折部102所形成的凹槽区域的至少部分区域。在具体实施过程中，固定胶40可以是完全填满弯折部102所形成的凹槽区域，如图2所示，还可以是仅填充凹槽区域的部分区域，如图5所示。在实际应用中可以根据对回弹力的削弱需求来填充固定胶40，在此不做限定。In the embodiment of the present invention, the fixingglue 40 fills at least a part of the groove area formed by the bendingportion 102 . In a specific implementation process, the fixingglue 40 may completely fill the groove area formed by the bendingportion 102 , as shown in FIG. 2 , or may only fill a part of the groove area, as shown in FIG. 5 . In practical applications, the fixingglue 40 can be filled according to the weakening requirement of the resilience, which is not limited here.

在本发明实施例中，沿靠近弯折轴的方向，固定胶40沿垂直于平板部101所在平面方向的厚度逐渐减小。结合图2所示的显示装置，离弯折轴越远，固定胶40沿垂直于平板部101所在平面方向的厚度越大，相应地，对弯折部102与固定部103紧邻位置处的回弹力的削弱效果越好，降低了对显示装置中可操作区AA内的相关膜层的损伤。此外，固定胶40在不同位置的不同厚度对弯折部102相应位置的应力进行相应的削弱，从而降低了设置在弯折部102的电路走线的断线风险，进而提高了显示装置的良率。In the embodiment of the present invention, along the direction close to the bending axis, the thickness of the fixingglue 40 gradually decreases along the direction perpendicular to the plane of theflat plate portion 101 . In combination with the display device shown in FIG. 2 , the further away from the bending axis, the greater the thickness of the fixingglue 40 along the direction perpendicular to the plane of theflat plate portion 101 . The better the weakening effect of the elastic force is, the damage to the relevant film layers in the operable area AA in the display device is reduced. In addition, the different thicknesses of the fixingglue 40 at different positions can correspondingly weaken the stress at the corresponding positions of the bendingportion 102 , thereby reducing the risk of disconnection of the circuit traces disposed on the bendingportion 102 , thereby improving the performance of the display device. Rate.

在本发明实施例中，沿靠近弯折轴的方向，固定胶40沿平行于平板部101所在平面方向的厚度逐渐增大。结合图2所示的显示装置，离弯折轴越近，固定胶40沿平行于平板部101所在平面方向的厚度越大，相应地，对弯折部102曲率最大处的应力的削弱效果越好，降低了设置在弯折部102的电路走线的断线风险。In the embodiment of the present invention, along the direction close to the bending axis, the thickness of the fixingglue 40 increases gradually along the direction parallel to the plane of theflat plate portion 101 . In combination with the display device shown in FIG. 2 , the closer it is to the bending axis, the greater the thickness of the fixingglue 40 along the direction parallel to the plane of theflat plate portion 101 , and correspondingly, the greater the weakening effect on the stress at the maximum curvature of the bendingportion 102 . Well, the risk of disconnection of the circuit traces disposed on thebent portion 102 is reduced.

在本发明实施例中，弯折部102外侧设置有保护胶层，该保护胶层可以是MCL胶层，这样的话，能够有效防止弯折部102弯折过程中对电路走线的损伤，进而提高显示装置的良率。In the embodiment of the present invention, the outer side of the bendingportion 102 is provided with a protective adhesive layer, and the protective adhesive layer may be an MCL adhesive layer. In this case, damage to the circuit traces during the bending process of the bendingportion 102 can be effectively prevented, and further Improve the yield of the display device.

如图7所示为本发明实施例提供的一种显示装置的其中一种结构示意图，具体来讲，第一支撑膜20背离平板部101的一侧依次设置有胶材层50、缓冲层60、散热层70。在具体实施例中，通过固定胶40削弱显示面板10的弯折部102因弯折所产生的回弹力，能够降低缓冲层60变形，甚至从胶材层50上崩开的风险，从而保证了缓冲层60对显示面板10的缓冲保护，以及散热层70对显示装置的散热效果，进而提高了显示装置的良率。FIG. 7 is a schematic structural diagram of a display device according to an embodiment of the present invention.

Similarly, peel off the release film attached to the opposite sides of the second support film, and set the second support film on the back of the fixed part. Then, the fixing part is bent to the back of the flat plate part through the bending part, and then, the fixing glue is filled into at least part of the groove area formed by the bending part. In a specific implementation process, after the fixing part is bent to the back of the flat plate part by the bending part, the fixing glue can be filled into at least part of the groove area formed by the bending part by means of injection molding. After the fixing glue is filled, the resilient force generated by the bending of the bending part is weakened to a certain extent by the fixing glue, thereby reducing the risk of deformation or even collapse of some film layers in the display device, and improving the yield.
