It can be understood that fig. 2-fig. 7 of the present embodiment are schematically illustrated by taking an example that the large to-be-cut display panel 100 includes 9 (3 × 3) irregular-shaped display panels 000, but are not limited thereto, and in specific implementation, the number of the irregular-shaped display panels 000 included in the large to-be-cut display panel 100 is not limited thereto. In this embodiment, the special-shaped display panel 000 is exemplified by a special-shaped panel with a structure Liu Haibing, but is not limited to this, and in specific implementation, the special-shaped display panel 000 may be a display panel including a special-shaped boundary with any shape. Fig. 3 of this embodiment illustrates only the number of the laser cutting tracks B1 that can be formed in the large display panel 100 to be cut, but is not limited to the laser cutting tracks B1 with such a design, and in a specific implementation, the number and the route of the laser cutting tracks B1 may be set according to actual requirements, and only the orthographic projection of the laser cutting tracks B1 on the substrate 10 needs to overlap at least with the orthographic projection of the irregular boundary 20 on the substrate 10, which is not limited in this embodiment.
In the related art, as shown in fig. 9 to 10, fig. 9 is a plan view of a profile display panel manufactured by a cutting method of a profile display panel in the related art, fig. 10 is a partially enlarged view of an R-angle position in fig. 9, and a cutting method of a profile display panel 000' in the related art, which is a method of cutting by using a large cutter wheel and laser by using a small laser: the reason why the hanging corner 20 'is formed is that in order to prevent the laser from thermally damaging the line in the frame of the display panel, the laser cannot start from the boundary of the tangent edge of the circular arc and the straight edge, and the laser can only start from the inner surface or start from the outer surface at an angle of an angle α', so that the laser path (indicated by a broken line B1 'in fig. 10) and the cutter wheel path (indicated by a broken line B2' in fig. 10) do not overlap, and the shaded area a 'in fig. 10 is directly left on the panel to form the hanging corner 20' at the time of peeling. The problem of hanging corners needs to spend a large amount of manpower and material resources to control and intercept, cannot be completely avoided, and has the possibility of missing detection; the hanging corners near the R corners of the special-shaped display panel occupy more product structure space, and are very easy to generate structural interference with other parts in a product mechanism test to cause fragment, or directly generate extending cracks inwards from the edges of the hanging corners when being impacted by external force to cause display abnormity, and the cutting method can only carry out laser operation on a certain fillet of a single small panel, can not simultaneously carry out cutting operation on fillets at other positions, and simultaneously stops the machine for changing the sheet after each operation is finished to influence the utilization rate of the machine. Therefore, the laser cutting of the cutting mode is easy to have the problems of laser sputtering and corner hanging caused by the heat influence of the laser, and the product yield is influenced. Based on the above problems, the embodiment further provides a method for cutting the special-shaped display panel, which can solve the problem of laser heat affected sputtering and the problem of corner hanging in the laser cutting in the prior art, and improve the yield and reliability of products.

s202: forming a laser cutting track B1 on the display panel 100 to be cut, wherein the laser cutting track B1 at least corresponds to the special-shaped boundary 20, an orthographic projection of the laser cutting track B1 on the substrate 10 at least partially overlaps with an orthographic projection of the special-shaped boundary 20 on the substrate 10, and the laser cutting track B1 is shown by a line with an arrow in FIG. 3;
s203: forming a cutter wheel cutting track B2 on the display panel 100 to be cut, wherein the cutter wheel cutting track B2 corresponds to the straight boundary 30, namely, the orthographic projection of the cutter wheel cutting track B2 on the substrate 10 is overlapped with the orthographic projection of the straight boundary 30 on the substrate 10, and the orthographic projection of the cutter wheel cutting track B2 on the substrate 10 is at least partially overlapped with the orthographic projection of the laser cutting track B1 on the substrate 10, and the cutter wheel cutting track B2 is shown by a dotted line in FIGS. 4 and 5;
s204: splitting the display panel 100 to be cut along the cutter wheel cutting track B2 to obtain a split panel 200, as shown in fig. 6;
s205: the sliced panel 200 is peeled along the laser cutting track B1 to obtain a shaped display panel 000, as shown in fig. 7.
In the method for cutting the special-shaped display panel provided by this embodiment, first, laser is performed on the whole large-piece display panel to be cut 100, a laser cutting track B1 is formed at a position corresponding to the special-shaped boundary 20 of each special-shaped display panel 000, after the laser is performed, the small-piece panel does not fall off from the large-piece display panel to be cut 100, then a knife wheel is used for performing linear cutting, a linear knife wheel cutting track B2 is formed, and an orthographic projection of the knife wheel cutting track B2 on the substrate 10 is partially overlapped with an orthographic projection of the linear boundary 30 on the substrate 10, that is, at least a part of the orthographic projection of the knife wheel cutting track B2 on the substrate 10 is intersected with an orthographic projection of the laser cutting track B1 on the substrate 10, and the intersection is mainly concentrated at a connection position of the special-shaped boundary 20 and the linear boundary 30 (a region C in fig. 4 and 5), therefore, laser can be simultaneously carried out on different areas of a large display panel 100 to be cut through multiple laser cutter heads, the reduction of equipment investment is facilitated, the cutting efficiency and the productivity are improved, the energy consumption is reduced, the pollution is reduced, the panel can be prevented from being frequently carried as much as possible, the damage to the panel possibly caused by carrying can be reduced, the yield of the cut product is further facilitated to be improved, at the same time, the abnormal hanging angle can be solved, the joint of the special-shaped boundary 20 and the straight boundary 30 does not need to be ground or secondarily strengthened after stripping, and the cutting efficiency and the product yield are facilitated to be improved.
In some optional embodiments, please refer to fig. 1-8, 11, and 12 in combination, fig. 12 is another schematic plan view of a laser cutting track formed on the display panel to be cut in fig. 2 after the laser cutting track is formed, in this embodiment, the laser cutting track B1 includes a cut-in point M and a cut-out point N located at two ends of the laser cutting track B1, and at least one of the cut-in point M and the cut-out point N does not overlap with an orthographic projection of the irregular boundary 20 on the substrate 10.
This embodiment explains that, when performing a laser operation, a laser cutting track B1 formed on the display panel 100 to be cut includes a cut-in point M and a cut-out point N, where the cut-in point M indicates a point on the display panel 100 to be cut when the laser starts performing the laser operation, the cut-out point N indicates a point on the display panel 100 to be cut when the laser completes one laser cutting track B1, and the cut-in point M and the cut-out point N are located at two ends of the one laser cutting track B1, respectively. In this embodiment, at least one of the cut-in point M and the cut-out point N in the laser cutting track B1 is not overlapped with the orthographic projection of the irregular boundary 20 on the substrate 10 (fig. 12 illustrates that the cut-in point M and the cut-out point N are not overlapped with the orthographic projection of the irregular boundary 20 on the substrate 10), that is, the point where laser is started and the point where one laser cutting track B1 is completed are not on the irregular boundary 20 of the irregular display panel 000, and laser is started from the periphery far from the boundary of the irregular display panel 000, so that laser is always cut in a uniform medium, and meanwhile, laser sputtering to the frame range of the irregular display panel 000 due to refraction and reflection of laser can be avoided, which causes the abnormality of frame lines (scanning driving circuits and the like in the frame area), and further, the thermal influence of laser sputtering to lines near the frame of the irregular display panel 000 can be avoided, the problem of laser sputtering is solved, and the yield of products is improved.
It can be understood that, as shown in fig. 12, the laser cutting tracks B1 formed on the shaped display panel 000 may be surrounded into an S shape, that is, the cut-in point M of each laser cutting track B1 is not limited to the same side of the display panel 100 to be cut, and after the previous laser cutting track B1 is completed, the operation of the next laser cutting track B1 may be directly performed on the same side of the cut-out point N of the previous laser cutting track B1, and then the cut-in point M of the next laser cutting track B1 is the same side of the cut-out point N of the previous laser cutting track B1.
A method for cutting a special-shaped display panel in the related art adopts a method of cutting by a large cutter wheel and laser by small pieces: the method comprises the steps of firstly cutting a large panel into a plurality of small panels by a cutter wheel, then carrying out laser cutting on the small panels by laser, firstly removing waste material areas with straight edge shapes by the cutter wheel, cutting the small panels, then carrying out laser removal on waste material areas with special shapes such as R angles (the general names of non-straight edges such as circular arcs, transition curves and the like) or gaps in Liu Haibing, and when the waste material areas with special shapes corresponding to the R angles (the general names of non-straight edges such as circular arcs, transition curves and the like) are too narrow or the waste material areas with special shapes corresponding to the gaps in Liu Haibing are too deep, the stripping operation after laser has poor separability, cannot smoothly strip the large panel, and is easy to separate incompletely to cause the problem of corner hanging. Based on the above problems, the embodiment further provides a method for cutting the special-shaped display panel, which can solve the problem of corner hanging in laser cutting in the prior art, increase the space for stripping, reduce the number of the corner hanging, and further improve the yield and reliability of products.
