When the cutting is performed along the X direction, the cut-off portion of the driving circuit 122 cannot normally transmit the driving signal to the pixel unit 1101 of the display area 110, so that the correspondingly connected pixel unit 1101 cannot be normally displayed, that is, the correspondingly connected pixel unit 1101 is also cut. When cutting along the X direction and the Y direction, the proportion of the part cut along the X direction and the part cut along the Y direction needs to be in a certain range, and the display panel obtained after cutting can have a good display effect. In this embodiment, the original display panel may be cut by laser cutting.

In this embodiment, the driving module 1221 located at the middle of the plurality of driving modules 1221 is electrically connected to one pixel unit 1101, and provides a corresponding driving signal; the two driving modules 1221 respectively located at two sides of the driving module 1221 at the middle position are electrically connected to another pixel unit 1101, and provide corresponding driving signals; the other two driving modules 1221 respectively located at two sides of the driving module 1221 at the middle position are electrically connected to the other pixel unit 1101, and provide corresponding driving signals; and so on.

And a cutting street is left between any two adjacent pixels 1111, so as to facilitate laser cutting along the cutting street.
Step 520, performing secondary packaging on the generated display panel 100;
specifically, when the original display panel is cut, the required three-sided frameless display panel 100 is generated, and the generated display panel 100 is packaged for the second time, so that the display panel 100 packaged for the second time can normally display.
Step 530, performing three-edge frameless splicing on the display panels 100 subjected to secondary packaging to form a spliced display panel 200.
Specifically, as shown in fig. 4, three-edge frameless splicing is performed on the multiple secondarily packaged display panels to form a required spliced display panel, so that the purpose that a large-area display screen can achieve a good splicing effect is achieved. Taking fig. 4 as an example, that is, the tiled display panel 200 includes 4 display panels 100, which specifically includes a display area 210, two non-display areas 220, two driving circuits 122, two bottom frames 123 and four COF layers 124, wherein one driving circuit 122, one bottom frame 123 and two COF layers 124 are disposed in one of the non-display areas 220, and the other driving circuit 122, the other bottom frame 123 and the other two COF layers 124 are disposed in the other non-display area 220. It is to be understood that the above description is intended to illustrate specific embodiments only, and therefore is not to be construed as limiting the application.
In the embodiment of the present application, the cutting ranges along the X direction and the Y direction are variable, and the display panel 100 can be formed into different sizes after being cut, so the display panel 100 of the embodiment of the present application is not particularly limited thereto.
Therefore, the splicing method of the application can avoid the splicing position frame from forming the non-displayed 'black area' under the condition that the display panel 100 is spliced in a large area, thereby influencing the visual effect and solving the problem that the better splicing effect in a large area cannot be realized, so that the splicing position frame of the display panel 100 cannot form the non-displayed 'black area' under the condition that the large-area splicing is carried out, thereby obtaining the better visual angle effect and improving the competitiveness of the product. Moreover, the cutting range of the optimized display panel 100 is variable, and the display panel 100 can be cut to obtain sizes of different sizes.
An embodiment of the present invention further provides a display device, which includes the display panel in the embodiments shown in fig. 2 to fig. 3. Wherein the display device includes, but is not limited to: the OLED panel, the mobile phone, the tablet computer, the navigator, the display and any electronic device or component with a display function are not particularly limited in this application.
The flow chart described in the present invention is only an example, and various modifications can be made to the chart or the steps in the present invention without departing from the spirit of the present invention. For instance, the steps may be performed in a differing order, or steps may be added, deleted or modified. It will be understood by those skilled in the art that all or a portion of the above-described embodiments may be practiced and equivalents thereof may be resorted to as falling within the scope of the invention as claimed.
It is to be understood that the invention is not limited to the examples described above, but that modifications and variations may be effected thereto by those of ordinary skill in the art in light of the foregoing description, and that all such modifications and variations are intended to be within the scope of the invention as defined by the appended claims.
