Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, but the present application may be practiced in other ways other than those described herein, and persons skilled in the art will readily appreciate that the present application is not limited to the specific embodiments disclosed below.
As described in the background art section, the bending form of the bending portion of the conventional bendable display panel is affected by the fluctuation of the process conditions, and is easily broken.
As shown in fig. 1 and 2, this is because the flexible display panel generally includes a flexible display 01 and a support layer 02 located on the non-display side of the flexible display 01, the support layer 02 includes a first support layer 03 and a second support layer 04 located on both sides of a bent portion a in the flexible display 01, respectively, to fix the non-bent configuration of the non-bent portion of the flexible display 01 located on both sides of the bent portion a. When the flexible display panel is specifically manufactured, the attaching precision of the attaching support layer on the non-display side of the flexible display panel fluctuates, so that the acting force applied to the bending part by the non-bending parts positioned on two sides of the bending part of the bendable display panel is unbalanced, and at the moment, if the acting force applied to the bending part by the non-bending parts positioned on two sides of the bending part of the bendable display panel is larger, the bending part of the bendable display panel is easy to break.
In addition, when specifically making, still can additionally increase the adhesive linkage and bond first supporting layer and second supporting layer together, in this process, if for first supporting layer with the effort of bonding first supporting layer and second supporting layer that the second supporting layer applyed can make the bending radius of the kink portion of kink display panel is too little, leads to kink display panel's non-kink portion that is located kink portion both sides give kink portion applyed effort is great for kink display panel's kink portion takes place to fracture.
In view of this, an embodiment of the present application provides a display panel, as shown in fig. 3 and 4, including: a display screen 10 and a support layer 20 on the non-display side of the display screen 10, optionally the display screen 10 is a flexible display screen. As further shown in fig. 3 and 4, in the present embodiment, the display panel includes: the first component 101, the second component 102 and the third component 103 connecting the first component 101 and the second component 102, where the third component 103 is a bending portion, and at least one of the supporting layer 20 and the display screen 10 is an arc-shaped side wall located in an area where the bending portion is located, so that the acting force applied to the bending portion by the first component 101 and the second component 102 is applied to the bending portion, and when the acting force is transmitted to the arc-shaped side wall, the acting force applied to the bending portion by the first component 101 and the second component 102 can be relieved along the component acting force in the first direction X by using the arc-shaped side wall, so that the acting force applied to the bending portion by the first component 101 and the second component 102 in the first direction X is reduced, and the probability of fracture of the bending portion due to the larger acting force applied to the bending portion is reduced.
It should be noted that, when the forces applied to the bending portion by the first component and the second component in the first direction are reduced, even if the forces applied to the bending portion by the first component and the second component in the first direction are different, the bending portion is not easy to break due to the smaller applied force, so that the process requirements in the manufacturing process of the display panel can be reduced.
Similarly, with the same bending radius, the force applied to the bending portion by the first component and the second component in the first direction is reduced, and the probability of breakage of the bending portion is also reduced.
In addition, in the display panel provided by the embodiment of the application, at least one of the supporting layer and the display screen is an arc-shaped side wall at the area where the bending part is located, so that the stress concentration point is avoided on the premise that the acting force applied to the bending part by the first component part and the second component part in the first direction is relieved by utilizing the arc-shaped side wall, and the phenomenon that the stress concentration point of the bending part is easy to break due to the occurrence of the stress concentration point is avoided.
In addition, in the display panel provided by the embodiment of the application, when the side wall part of at least one of the supporting layer and the display screen, which is located in the area where the bending part is located, is an arc side wall, in the bending process of the display panel, the bending force born by the arc side of the arc side wall is smaller, so that the probability of excessive bending of the bending part of the display panel can be reduced, and the probability of breakage of the bending part of the display panel is reduced.
Optionally, in an embodiment of the present application, as shown in fig. 3, the curved side wall is symmetrical about the bending axis DE of the bending portion, so that the bending axis DE of the bending portion is located in the central line area of the curved side wall in the first direction X, and thus the alleviating effect of the curved side wall on the acting force applied by the first component 101 and the second component 102 on the bending portion is the same, and the probability that the acting forces applied by the first component 101 and the second component 102 on the bending portion are different is reduced.
On the basis of any of the above embodiments, in one embodiment of the present application, as shown in fig. 5, a sidewall portion of the display screen 10 in the area where the bending portion is located is an arc sidewall. Specifically, in the embodiment of the present application, as further shown in fig. 5, the display screen 10 includes a first portion 11, a second portion 12, and a third portion 13 connecting the first portion 11 and the second portion 12, where the third portion 13 is located at a bending portion of the display panel. In the embodiment of the present application, the side wall of the third portion 13 of the display screen 10 is an arc-shaped side wall in the second direction Y, where the second direction Y is perpendicular to the first direction X and parallel to the plane of the display panel, that is, in the present embodiment, in the plane of the display panel, the side wall of the third portion 13 of the display screen 10 is arc-shaped, so that when the first portion 11 and the second portion 12 apply bending force to the third portion 13, the arc-shaped side wall of the third portion 13 can be used to relieve the force applied to the third portion 13 by the first portion 11 and the second portion 12 in the first direction X, thereby reducing the probability of breakage of the third portion 13 and further reducing the probability of breakage of the display panel.
Alternatively, in one embodiment of the present application, the third portion 13 of the display screen includes a first sidewall 131 and a second sidewall 132 opposite to each other in the second direction Y, and the distance between the first sidewall 131 and the second sidewall 132 increases and decreases along the first direction X, so that the sidewall of the third portion 13 is an arc sidewall, but the present application is not limited thereto, and in other embodiments of the present application, the distance between the first sidewall and the second sidewall may decrease and then increase in the second direction, which is not limited thereto, so long as the sidewall of the third portion of the display screen is ensured to be an arc sidewall.
It should be noted that, when the distance between the first side wall and the second side wall increases first and then decreases along the first direction, that is, when the third portion of the display screen has an arc-shaped side wall with a convex shape, compared with the distance between the first side wall and the second side wall decreases first and then increases along the second direction, the third portion has stronger strength and can strengthen the strength of the edge area of the third component of the display panel, thereby avoiding that the bending radius of the bending portion is too small when the bending portion of the display panel is bent, and further avoiding that the bending portion of the display panel is broken due to the too small bending radius of the bending portion.
On the basis of any of the above embodiments, in one embodiment of the present application, as shown in fig. 5 and 6, when the sidewall of the third portion 13 of the display screen 10 is an arc sidewall, the supporting layer 20 includes a first supporting portion 21 corresponding to the first portion 11 and a second supporting portion 22 corresponding to the second portion 12, where the first supporting portion 21 supports and fixes the form of the first portion 11 of the display screen 10, and the second supporting portion 22 supports and fixes the form of the second portion 12 of the display screen. It should be noted that, in this embodiment, a gap is formed between the first supporting portion 21 and the second supporting portion 22, and the gap corresponds to the third portion 13 of the display screen 10, so as to avoid that the bending performance of the display screen is affected by the arrangement of the supporting layer 20.
On the basis of any of the above embodiments, in one embodiment of the present application, as shown in fig. 7, the sidewall portion of the support layer 20 in the area where the bending portion is located is an arc sidewall, specifically, in one embodiment of the present application, as shown in fig. 7 and 8, the support layer 20 includes a first support portion 21 corresponding to the first portion 11 and a second support portion 22 corresponding to the second portion 12, and a third support portion 23 corresponding to the third portion 13 and connecting the first support portion 21 and the second support portion 22, where the first support portion 21 supports and fixes the form of the first portion 11 of the display screen 10, and the second support portion 22 supports and fixes the form of the second portion 12 of the display screen 10, and the third support portion 23 is located at the bending portion. In this embodiment, the side wall of the third supporting portion 23 is an arc-shaped side wall, so that when the first portion 11 and the second portion 12 apply bending force to the third portion 13, the arc-shaped side wall of the third supporting portion 23 can be used to relieve the force applied to the third portion 13 by the first portion 11 and the second portion 12 in the first direction X, so as to reduce the probability of breaking the third portion 13, and further reduce the probability of breaking the display panel.
It should be noted that, in the above embodiment, the side wall portion of the display screen 10 located in the area where the bending portion is located may be an arc side wall, as shown in fig. 9, or may not be an arc side wall, as shown in fig. 10, which is not limited in this aspect of the application, and is specific as the case may be.

The second direction Y is perpendicular to the first direction X and parallel to the plane of the display panel. It should be noted that, in this embodiment, as further shown in fig. 7, a gap 233 is provided between the first sub-portion 231 and the second sub-portion 232, and the gap 233 corresponds to the third portion of the display screen, so that the bending performance of the display screen is not affected on the basis that the supporting layer 20 includes the third supporting portion 23.
Specifically, on the basis of the above embodiment, in one embodiment of the present application, as further shown in fig. 7, in the second direction Y, a side wall of the first subsection 231 on a side far from the second subsection 232 is an arc-shaped side wall, and a side wall of the second subsection 232 on a side far from the first subsection 231 is an arc-shaped side wall, so that both side walls of the third supporting portion 23 in the second direction Y are arc-shaped side walls. However, the present application is not limited thereto, and in other embodiments of the present application, two sidewalls of the third supporting portion in the second direction may be curved sidewalls, and the other may be other than curved sidewalls, for example: as shown in fig. 11, in the second direction Y, the side wall of the first subsection 231 far from the second subsection 232 is an arc-shaped side wall, the side wall of the second subsection 232 far from the first subsection 231 is not an arc-shaped side wall, or, as shown in fig. 12, in the second direction Y, the side wall of the first subsection 231 far from the second subsection 232 is not an arc-shaped side wall, and the side wall of the second subsection 232 far from the first subsection 231 is an arc-shaped side wall, as the case may be.
On the basis of the above embodiment, in one embodiment of the present application, as further shown in fig. 7, in the second direction Y, the distance between the side wall of the first subsection 231 away from the second subsection 232 and the side wall of the second subsection 232 away from the first subsection 231 is increased and then decreased along the first direction X, so that the side wall of the third supporting portion 23 is an arc-shaped side wall, but the present application is not limited thereto, and in other embodiments of the present application, in the second direction, the distance between the side wall of the first subsection away from the second subsection and the side wall of the second subsection away from the first subsection may also be decreased and then increased along the first direction, as the case may be.
On the basis of any of the above embodiments, in one embodiment of the present application, as shown in fig. 13, the display panel includes a display area 100 and a non-display area 200, and the bending portion is located in the non-display area 200 of the display panel, that is, the third component 23 of the display panel is located in the non-display area of the display panel. Specifically, in this embodiment, the display portion of the display screen is located in the first portion of the display screen, and the driving circuit portion of the display screen is located in the second portion of the display screen, where the driving portion includes a driving circuit 30, and the driving circuit 30 is configured to drive the display portion to display, but the present application is not limited thereto, and in other embodiments of the present application, the bending portion may also be a display area of the display panel, as the case may be.

Correspondingly, the embodiment of the application provides a manufacturing method of the display panel, which is used for manufacturing the display panel provided by any embodiment. Specifically, in an embodiment of the present application, the display panel includes: the first component part, the second component part and the third component part which are arranged along the first direction and are connected with the first component part and the second component part, and the third component part is a bending part; as shown in fig. 16, the manufacturing method includes:

Specifically, in one embodiment of the present application, as shown in fig. 5 and 6, the display screen 10 includes a first portion 11 and a second portion 12, and a third portion 13 connecting the first portion 11 and the second portion 12, where the third portion 13 is located at a bending portion of the display panel; the support layer 20 includes: a first supporting portion 21 corresponding to the first portion 11 and a second supporting portion 22 corresponding to the second portion 12, wherein the first supporting portion 21 supports and fixes the shape of the first portion 11 of the display screen 10, and the second supporting portion 22 supports and fixes the shape of the second portion 12 of the display screen 10; in this embodiment, the fixing support layer on the non-display side of the display screen includes: a first support portion 21 of the support layer 20 is fixed to the non-display side of the first portion 11 of the display screen 10 and a second support portion 22 of the second support layer 20 is fixed to the non-display side of the second portion 12 of the display screen 10. It should be noted that, in this embodiment, a gap is formed between the first supporting portion 21 and the second supporting portion 22, and the gap corresponds to the third portion 13 of the display screen 10, so as to avoid that the bending performance of the display screen 10 is affected by the arrangement of the supporting layer 20.
In the foregoing embodiment, cutting the whole body formed by the display screen and the supporting layer, so that the arc-shaped side wall of the side wall portion of at least one of the supporting layer and the display screen, where the bending portion is located, includes: as shown in fig. 17, the whole of the display screen 10 and the supporting layer 20 is cut, so that the sidewall portion of the display screen 10 in the area where the bending portion is located is an arc sidewall, as shown in fig. 18. That is, in the embodiment of the present application, the side wall of the area where the bending portion is located of the display screen 10 is an arc-shaped side wall, and the supporting layer 20 is not located of the area where the bending portion is located, as shown in fig. 18, so that when the first portion 11 and the second portion 12 apply bending force to the third portion 13, the arc-shaped side wall of the third portion 13 can be used to relieve the first direction X, and the force applied to the third portion 13 by the first portion 11 and the second portion 12 reduces the probability of breaking the third portion 13, thereby reducing the probability of breaking the display panel.
In another embodiment of the present application, as shown in fig. 8, the display screen 10 includes a first portion 11 and a second portion 12, and a third portion 13 connecting the first portion 11 and the second portion 12, the third portion 13 corresponding to a bending portion of the display panel; as shown in fig. 8 and 9, the supporting layer 20 includes a first supporting portion 21 corresponding to the first portion 11, a second supporting portion 22 corresponding to the second portion 12, and a third supporting portion 23 corresponding to the third portion 13 and connecting the first supporting portion 11 and the second supporting portion 12, where the first supporting portion 21 supports and fixes the shape of the first portion 11 of the display screen 10, the second supporting portion 22 supports and fixes the shape of the second portion 12 of the display screen 10, and the third supporting portion 23 is located at the bending part; in this embodiment, cutting the whole body formed by the display screen and the supporting layer, so that at least one of the supporting layer and the display screen is located in the area where the bending portion is located, where the side wall portion is an arc-shaped side wall includes: as shown in fig. 19, the whole body formed by the display screen 10 and the supporting layer 20 is cut, so that the side wall portions of the display screen 10 and the supporting layer 20 in the area where the bending portion is located are arc side walls, as shown in fig. 20, when the bending force is applied to the third portion 13 by the first portion 11 and the second portion 12, the arc side wall of the third portion 13 can be used to relieve the first direction, the force applied to the third portion 13 by the first portion 11 and the second portion 12 can be used to reduce the breaking probability of the third portion 13, and further reduce the breaking probability of the display panel by reducing the breaking probability of the display panel by using the arc side wall of the third supporting portion 23, and the breaking probability of the third portion 13 by using the force applied to the first portion 11 and the second portion 12 is further reduced.
As shown in fig. 21, fig. 21 is a schematic diagram showing stress applied to different positions of a bending portion of a display panel with different structures during bending, wherein an abscissa indicates a distance between each position of the bending portion of the display panel and an edge thereof in a second direction, and an ordinate indicates stress applied to each position of the bending portion of the display panel. The curve a is a schematic diagram of stress applied to different positions of the bending part of the display panel when the display screen in the display panel is located at the bending part of the display panel and the supporting layer is not located at the bending part area (corresponding to the structure shown in fig. 1) of the display panel; curve b is a schematic diagram of stress applied to different positions of the bending portion of the display panel when the display screen in the display panel is located at the bending portion of the display panel and the supporting layer is not located at the bending portion region (corresponding to the structure shown in fig. 18) of the display panel; the curve c is a stress diagram of the bending part of the display panel when the side wall of the bending part of the display panel is an arc side wall, and the side wall of the supporting layer part of the display panel is also an arc side wall (corresponding to the structure shown in fig. 20).
As can be seen from fig. 21, in the second direction, the stress applied to the edge of the display panel is smaller than the curve b and smaller than the curve a, that is, the stress applied to the edge of the bending portion of the display panel in the second direction in the structure shown in fig. 20 during bending is much smaller than the stress applied to the edge of the bending portion of the display panel in the second direction in the structure shown in fig. 18 during bending, which is much smaller than the stress applied to the edge of the bending portion of the display panel in the second direction in the structure shown in fig. 1 during bending. Therefore, the display panel provided by the embodiment of the application can obviously improve the stress born by the edge of the bending part of the display panel in the second direction in the bending process.
