All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
For the convenience of clearly describing the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, the words "first", "second", "third", and the like are used to distinguish the same items or similar items with basically the same functions and actions, and those skilled in the art can understand that the words "first", "second", "third", and the like do not limit the quantity and execution order.
Example one
The embodiment of the invention provides a display panel, which comprises at least one arc-shaped side edge and a plane area connected with the arc-shaped side edge, and also comprises a folding area positioned on the arc-shaped side edge and a terminal area connected with the folding area;
the folding area is bent to enable the terminal area to be bent to the non-display side of the display panel;
the display panel further comprises a fixing part, and the fixing part is located between the terminal area and the arc-shaped side edge and used for fixing the terminal area.
The type of the Display panel is not limited, and it may be an LCD (Liquid Crystal Display) or an OLED (Organic Light-Emitting Diode). The display panel may be a flexible display panel (also referred to as a flexible screen) or a rigid display panel (i.e., a display panel that cannot be bent), and is not limited herein, as long as the display panel has at least one arc-shaped side. The number of curved sides and the number of terminal areas are not limited here either. In order to reduce the frame of the display panel to a greater extent, the display panel generally needs only one terminal area.
The planar area may be provided with a first substrate and a second substrate of the pair of cassettes; for example, the first substrate may be a color film substrate, the second substrate may be an array substrate, and liquid crystal may be disposed between the first substrate and the second substrate, so that a liquid crystal display panel may be formed; or, the first substrate may also be an encapsulation substrate, the second substrate may also be a substrate, and a thin film transistor, an OLED, and the like may be disposed on the substrate, so that an OLED display panel may be formed. Of course, the above-mentioned plane area can also be equipped with heat-dissipating film (named SCF in the industry) to facilitate heat dissipation; further, in order to realize the fingerprint recognition function, a Touch Sensor, such as a PST (Polarizer Sensor Touch), may be further disposed in the planar area, and the Touch Sensor may be fixed to an adjacent structure by an OCA (Optically Clear Adhesive); in order to better realize the display, the flat area may be further provided with a Cover Glass (CG). The planar region may be further provided with other layers and structures, which are not described in detail herein.
The side of the display panel on which display is realized is referred to as a display side, and the side opposite to the display side is referred to as a non-display side.
The curved direction of the arc-shaped side is not limited, and may be curved from the display side to the non-display side or curved from the non-display side to the display side. The former is preferable in view of practicality and reduction of the frame. The embodiment of the present invention is described by taking an example in which the curved direction of the curved side is curved from the display side to the non-display side. The curved sides may also be provided with other areas, for example: a lead region (Fanout region), etc., which will not be described in detail herein.
The embodiment of the invention provides a display panel, which realizes the bending of a terminal area on an arc surface, and has the advantages of high yield and low manufacturing cost.
There are many specific ways of bending the terminal area to the non-display side of the display panel, and three bending ways will be described in detail below.
FIG. 1 shows a display panel in a state before a folding region and a terminal region of the display panel are bent, wherein the display panel of FIG. 1 sequentially comprises a glass cover plate 1, a touch layer 2, a box-opposing substrate 3 and a heat dissipation film 4 along an OA direction, the outer side of the glass cover plate is a display side, and the bending direction of the arc-shaped side edge is from the display side to a non-display side. Of course, the display panel may also include other film layers and structures, and the structure shown in fig. 1 is only used as an example for illustration. The terminal area of the display panel shown in fig. 1 can be bent in the following three ways.
First, as shown in fig. 2, the terminal area 10 includes a flat portion 101 and a bent portion 102; the degree and direction of curvature of curved portion 102 is the same as the degree and direction of curvature of curved side 20, respectively. Namely, the terminal area is bent along the cambered surface of the cambered side edge. Compared with other two bending modes, the bending mode has the minimum influence on the thickness of the display panel.
Second, the display panel after being bent can be seen from fig. 3, in which the plane of the substrate (not shown) of the terminal area 10 and the plane of the substrate (not shown) of the plane area 30 form an included angle. In the bending mode, the bending angle of the terminal area is small, the probability of wire breakage is low, and the product yield is high.
Third, the display panel after being bent can be seen from fig. 4, in which the plane of the substrate (not shown) of the terminal area 10 is parallel to the plane of the substrate (not shown) of the planar area 30. In this kind of mode of bending, the substrate place plane of terminal area is parallel with the substrate place plane of plane area, is favorable to follow-up overlap joint COF (Chip On Film, the Flexible Printed Circuit board of encapsulation Chip) or FPC (Flexible Printed Circuit board) etc. like this, and simultaneously, the angle of bending of terminal area further reduces, and the probability that takes place the broken string is low, and the product yield is high.
In the third bending method, in order to compensate for the height difference and save the terminal space structure, and to reduce the thickness of the display panel as much as possible, it is preferable that the fixing portion 40 includes a terminal device 41 and an adhesive portion 42, as shown in fig. 5. The bonding portion is located between the terminal area and the terminal device and is bonded to the terminal device and the terminal area, respectively.
The terminal device here may be a battery, a motherboard, etc. The adhesive portion may be a double-sided tape, for example: PET Tape (polyester double-sided Tape) including a PET Tape and a double-sided Tape on both sides of the PET Tape. Of course, the adhesive portion may be other adhesive materials, which are not listed here.
For the display panel of any one of the above, optionally, the fixing portion includes: the display device comprises a first viscous part, fixing glue and a second viscous part, wherein the first viscous part is positioned on one side of the fixing glue close to the non-display side, and the second viscous part is positioned on one side of the fixing glue far away from the non-display side. The first adhesive part and the second adhesive part may be double-sided tapes, and the fixing glue may be PET glue.
Preferably, in order to fix the terminal area better, the fixing part at least fills the space surrounded by the terminal area, the arc-shaped side edge and the folding area. Of course, if the terminal area also extends to a position opposite to the planar area, the fixing portion also fills the gap between the terminal area and the planar area.
Optionally, the display panel further includes a circuit board, the circuit board is located on the non-display side of the display panel and is overlapped with the terminal area; the fixing portion also fills the gap between the circuit board and the planar area and the gap between the terminal area and the planar area. The circuit structure and the components included in the circuit board are not limited, and may be determined according to actual conditions. The wiring board may be a COF or an FPC. The lapping mode of the circuit board and the terminal area is not limited.
The following describes the way of overlapping the circuit board and the terminal area and the structure of the fixing portion, respectively, with respect to the display panel shown in fig. 2, 3 and 4. In fig. 2, the circuit board 50 is horizontally disposed and directly overlaps the terminal area 10, and the fixing portion 40 can be referred to as fig. 6. In fig. 3, one end of the circuit board 50 directly overlaps the terminal area 10, and the rest is bent to be horizontal, and the fixing portion 40 can be referred to as fig. 7. In fig. 4, the circuit board 50 is horizontally disposed and directly overlaps the terminal area 10, and the fixing portion 40 can be referred to as fig. 8.
Optionally, the display panel further includes: the display device comprises a first display area, a second display area and a lead area, wherein the first display area is located in a plane area, the second display area and the lead area are located on arc-shaped side edges, and the lead area is located between the second display area and a folding area. The second display area is arranged on the arc-shaped side edge, and display can be achieved on the arc-shaped side edge, so that the display area is increased, and the customer experience is improved. The lead wire area is arranged on the arc-shaped side edge, so that the frame can be further reduced, and the requirement of a consumer on the extremely frame can be better met.
In order to ensure the accuracy of the terminal area after bending and improve the yield of products, the display panel needs to be aligned after bending. In order to facilitate the alignment operation, alignment marks (marks) need to be formed on the display panel. Two ways are provided below.
First, the display panel further includes: the display panel comprises a first alignment mark and a second alignment mark, wherein the first alignment mark is positioned in a lead wire area of the display panel, and the second alignment mark is positioned in a terminal area.
Second, the display panel further includes: the alignment mark comprises a first alignment mark and a second alignment mark, wherein the first alignment mark is located in the plane area, the second alignment mark is located in the terminal area, and projections of the first alignment mark and the second alignment mark on the substrate of the plane area along a direction perpendicular to the substrate of the plane area are overlapped. The overlap may be a complete overlap or a partial overlap, and is determined according to the shapes and the alignment accuracy of the first alignment mark and the second alignment mark.
In the above two modes, the shape, size and number of the first alignment mark and the second alignment mark are not limited. The first alignment mark and the second alignment mark may have the same shape or different shapes. Preferably, the first alignment mark may have a T-shape, and the second alignment mark may have a cross-shape. Therefore, the method is favorable for distinguishing and is not easy to be confused in operation.

The embodiment of the invention provides a preparation method of a display panel as described in the first embodiment, which comprises the following steps:
step 201: a fixing portion is formed on the non-display side of the display panel.
Step 202: the folding area is bent so that the terminal area is bent to the non-display side of the display panel and fixed with the fixing portion.
The embodiment of the invention provides a preparation method of a display panel, the display panel can be manufactured through the preparation method, and the preparation method is simple and easy to implement.
EXAMPLE III
The embodiment of the invention provides a preparation method of a display panel according to the first embodiment, which comprises the following steps:
step 301: forming a first adhesive part and a fixing adhesive on the non-display side of the display panel;
step 302: forming a second adhesive part on the side where the folding region is fixed with the fixing part;
step 303: the folding area is bent so that the terminal area is bent to the non-display side of the display panel, and the second adhesive part is bonded with the fixing glue.
In the display panel formed by the above manufacturing method, the fixing portion includes: the display device comprises a first viscous part, fixing glue and a second viscous part, wherein the first viscous part is positioned on one side of the fixing glue close to the non-display side, and the second viscous part is positioned on one side of the fixing glue far away from the non-display side. The preparation method is simple and easy to implement.
Example four
An embodiment of the present invention provides an alignment system for a display panel as described in the first embodiment, in which the first alignment mark is located in a lead area of the display panel, and the second alignment mark is located in a terminal area.
The above-mentioned counterpoint system still includes: a camera, as shown in fig. 9 to 11, the camera 5 is disposed along a first direction OB to be able to simultaneously grasp the first alignment mark 71 and the second alignment mark 72, the first direction intersecting a plane in which a substrate (not shown in the figure) of the display panel is located. At this time, the camera is disposed obliquely with respect to the display panel. The type of camera is not limited here, and it may be a CCD (Charge Coupled Device) camera.
It should be noted that, in the conventional process, the distribution of the first alignment marks and the second alignment marks in the flattened state of the side edge of the display panel can be referred to as shown in fig. 12. At this moment, the camera is horizontally arranged, is positioned right above the display panel and can simultaneously capture the first alignment mark and the second alignment mark. However, when the side of the display panel is an arc-shaped side, as shown in fig. 13, the first alignment mark 71 in the lead region 60 and the second alignment mark 72 in the terminal region 10 are both located on the arc surface. With the existing process and the existing equipment, the camera cannot capture the first alignment mark and the second alignment mark well due to the limitation of the depth of field and the position. Therefore, the present embodiment proposes the above improved method, and changes the installation position of the camera to simultaneously capture the clear first alignment mark and the clear second alignment mark.
The embodiment of the invention provides an alignment system of a display panel, which can realize alignment of the display panel on the premise of less change of the original process so as to ensure the manufacturing precision and improve the yield of the panel.

The type of camera is not limited here, and may be a CCD camera. The position, material and type of the optical lens are not limited here either. For example, the optical mirror may be a prism, and in this case, the prism may reflect the first alignment mark of the arc surface to a position parallel to the second alignment mark. The image formed by the optical mirror on the first alignment mark may be an enlarged image, an original image, or a reduced image, and in order to further improve the alignment accuracy, the image formed by the optical mirror on the first alignment mark is preferably an original image. Fig. 17 is a plan view of the display panel viewed from the non-display side to the display side after the terminal area is bent.
In this embodiment, on the premise that the position of the original camera is not changed, the first alignment mark is imaged by the optical lens to change the position of the first alignment mark, so that the camera can simultaneously capture the imaging of the first alignment mark on the optical lens and the second alignment mark, thereby realizing the alignment of the display panel, further ensuring the manufacturing accuracy and improving the yield of the panel.
