Description

Technical Field

[0001] The present application relates to the field of display, and in particular to a display panel and a display device. Background Art

[0002] In the current display panel manufacturing process, the electrical signals of the driving circuit must be transmitted to the display panel through a module process involving bonding of a chip-on-film or printed circuit board. Due to the limitations of the bonding process, the signal lines within the display panel are usually concentrated to a predetermined bonding area through a fan-out area, and then the chip-on-film or printed circuit board is bonded. Finally, an electrical connection is formed between the printed circuit board and the display panel, resulting in a larger border area. The size of the border is a crucial indicator of the quality of a spliced display screen, and the size of the border is mainly limited by the height of the fan-out wires and the external lead soldering area. Current narrow-border products mostly use narrow bonding, side bonding, or back bonding processes to achieve narrow or borderless borders by reducing the height of the external lead soldering area. However, the high bonding equipment required for narrow, side, or back bonding, as well as the low process maturity of the side-transfer silver wire technology, are not conducive to the development of spliced displays.

[0070] In the above embodiment of the present application, the manufacturing method of the display panel 100 is as follows:

[0071] First, after the thin film transistor array layer 120 is prepared on the first substrate 10, the second substrate 20 of the same thickness or different thickness is used to bond the second substrate 20 and the first substrate 10 together using a material similar to glass seam remover, and then the second metal wire 22 and the third metal wire 32 are prepared by a physical vapor deposition process, so that the second metal wire 22 is electrically connected to the first metal wire 13 through the third metal wire 32; wherein, the second substrate 20 can be oriented at 90 degrees or other angles with the first substrate 10; then, a binding process is performed on the second substrate 20; finally, a light-emitting layer is prepared on the first substrate 10.

In this case, each of the display panels 100 can be borderless on all four sides.
