Problems solved by technology

[0004] However, in the lower frame area of ​​the display panel (that is, the side connected to the integrated circuit), multi-layer wiring needs to be provided, such as data lines, power lines, etc., and compared to other film layers, the film layer of the power line It is thick and uneven, and the wiring of each layer overlaps with each other, making the surface of the area covered by the glass glue on the lower frame uneven, so that when the glass glue is melted and solidified, the deformation and stress caused by thermal expansion and contraction of the glass glue at different positions are also different. Glass glue is prone to wrinkles at places with high stress, resulting in reduced package reliability

Abstract

The invention discloses a display panel and a manufacturing method thereof and a display device. The display panel comprises an array substrate, a cover board and a sealant; a first power metal line and a metal transfer layer are arranged in an area, covered by the sealant, of the array substrate; the metal transfer layer comprises a plurality of metal transfer lines; the metal transfer lines areelectrically connected with the first power metal line and extend to a display area of the display panel from the area covered by the sealant. According to the display panel, films in a lower border area are relatively flat through arranging the first power metal line in packaging areas at the left side and the right side of the display panel, thereby improving the packaging reliability of the display panel.

Description

technical field [0001] The present application generally relates to the field of display technology, and in particular relates to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] With the development of information technology, liquid crystal display (LCD, Liquid Crystal Display) equipment and organic light emitting diode (OLED, Organic Light Emitting Diode) display equipment, as two mainstream display equipment, are more and more widely used in various portable in electronic equipment. [0003] Since the liquid crystal material or the organic light-emitting material is easily affected by oxygen and moisture and causes failure, it is necessary to provide high-reliability packaging to prevent oxygen, moisture, etc. from entering the display panel. Glass glue is an inorganic frame sealant, which can be melted and solidified by laser irradiation, and is often used in the packaging of display panels (especially organic light-em...
