The above technical solution is described below with reference to specific embodiments.
A manufacturing method of a special-shaped display panel is characterized in that the special-shaped display panel is a liquid crystal display panel (the size is 55-88 inches), and the liquid crystal display panel comprises an array substrate, an array substrate and a liquid crystal layer, wherein the array substrate is arranged opposite to a color film substrate, and the liquid crystal layer is positioned between the array substrate and the color film substrate. The manufacturing method comprises the following steps:
s10, providing a display panel;
specifically, as shown in fig. 1A, a display panel 10 is provided. The display panel 10 is rectangular. A plurality of small-sized display panels, namely, the display panels 10 to be cut in this application, are obtained by cutting one large-sized panel.
S11: and cutting the display panel 10 according to a preset cutting track, and splitting to form the special-shaped display panel 40.
The preset cutting track corresponds to a boundary of the special-shaped display panel 40, that is, the preset cutting track coincides with an outer contour line of the special-shaped display panel 40. The preset cutting track is annular and comprises at least one special-shaped section and at least one straight line section. The special-shaped section can be an arc section, the arc section corresponds to a large R angle on the special-shaped display panel, and the special-shaped section can also be other non-linear sections. And the entry tangent point and the exit tangent point of the preset cutting track are superposed and are positioned at any point on the straight line segment. For example, the entry point may be located at the midpoint of a straight line segment. As shown in fig. 1B, the irregular segment of the preset cutting track includes a first arc segment 311, a second arc segment 312, a third arc segment 313 and a fourth arc segment 314, the straight segment of the preset cutting track includes a first straight segment 211, a second straight segment 212, a third straight segment 213 and a fourth straight segment 214, two ends of the first straight segment 211 are respectively connected with the first arc segment 311 and the second arc segment 312, two ends of the second straight segment 212 are respectively connected with the second arc segment 312 and the third arc segment 313, two ends of the third straight segment 213 are respectively connected with the third arc segment 313 and the fourth arc segment 314, and two ends of the fourth straight segment 214 are respectively connected with the fourth arc segment 314 and the first arc segment 311. The first arc segment 311, the second arc segment 312, the third arc segment 313 and the fourth arc segment 314 are all the same. The first linear segment 211 is identical to the third linear segment 213 and the second linear segment 212 is identical to the fourth linear segment 214. The entry point a and the exit point a are located on the first straight line segment 211, the entry point a may be located at a midpoint of the first straight line segment 211, the entry point a may also be located at a side of the first straight line segment 211 close to the first circular arc segment 311, and the entry point a may also be located at a side of the first straight line segment 211 close to the second circular arc segment 312. The entry point a may be located at any point on the second straight line segment 212, the third straight line segment 213, and the fourth straight line segment 214. It should be noted that, when the straight line segment is connected with the special-shaped segment, the point of entry tangent a and the point of exit tangent a are points other than the transition point between the straight line segment and the special-shaped segment, which is more favorable for improving the yield of finished products of the special-shaped display panel.
When the display panel 10 is cut, the display panel 10 is cut along a preset cutting track by using a laser or a cutter wheel. In the cutting process, the cutting speed corresponding to the straight line section is higher than the cutting speed corresponding to the special-shaped section. The display panel 10 is cut along a preset cutting track in the directions of a1, a2, a3, a4, a5, a6, a7, a8 and a9 in sequence by taking the point a as an in-cut point, and the display panel is cut counterclockwise by taking the point a as an out-cut point, that is, by taking the point a as an in-cut point and taking the out-cut point along the preset cutting track, so as to form the special-shaped display panel 40 shown in fig. 1C. It is understood that the point a may be used as the in-tangent point and the out-tangent point may be cut clockwise along the preset cutting track.
The radius of the circular arc segments (including the first circular arc segment 311, the second circular arc segment 312, the third circular arc segment 313 and the fourth circular arc segment 314) is 10 mm-100 mm. Further, the radius of the circular arc segment can also be 30 mm-60 mm.
The angle B of the circular arc section is 30-150 degrees. Further, the radius of the circular arc section is 70-90 degrees, so that the special-shaped display panel has a more attractive outline.
The distance d from the straight line segment (including the first straight line segment 211, the second straight line segment 212, the third straight line segment 213 and the fourth straight line segment 214) to the edge of the display panel 10 is 2 mm to 10 mm. Too small distance d may cause inconvenient display panel splitting, and too large distance d may cause too low utilization rate when the display panel is manufactured into a special-shaped display panel.
The method for manufacturing the special-shaped display panel is characterized in that when the cut-in point of the preset cutting track is located on the straight line segment, the transition from the straight line segment to the special-shaped segment can be more natural, and when the cut-in point is on the straight line, the angle problem of the cut-in point does not need to be considered, the cut-out point and the cut-in point are overlapped to enable the position of the display panel needing splitting to be cut, no stress effect exists during splitting, the splitting is easier, and therefore the probability that the special-shaped display panel generates defects is reduced. Compared with the traditional manufacturing method based on the consideration of the utilization rate of the display panel, the method is characterized in that the four corners of the display panel are directly cut to form the special-shaped display panel, so that the special-shaped display panel is easy to have defects, and the finished product yield of the special-shaped display panel manufactured by the manufacturing method is improved. In addition, this application is through once cutting in order to form special-shaped display panel, divide into many times in order to form special-shaped display panel for traditional technique, and this application special-shaped display panel's manufacturing method is more simplified.
The application also provides the special-shaped display panel manufactured by the special-shaped display panel manufacturing method.
