Problems solved by technology

Since the OLED display panel cannot be cut directly by cutting tools, manual peeling is required after cutting, which will cause micro-cracks on the edge section of the OLED display panel and affect the strength of the OLED display panel.

Abstract

The invention provides a cutting method for a display panel. The display panel comprises a substrate, a cover plate opposite to the substrate, a plurality of display components located between the substrate and the cover plate and a packaging adhesive located between the substrate and the cover plate and respectively arranged around the plurality of display components. The cutting method comprises the steps: cutting the substrate and the cover plate of the display panel between two adjacent display components to form a plurality of display modules; and grinding the edges of the cut display modules by using an edge grinding device, and grinding the edges of the display modules into the packaging adhesive until the packaging adhesive is ground to the preset width. By using the cutting method for the display panel, provided by the invention, the design of a narrow frame of the display panel can be precisely realized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for cutting a display panel. Background technique [0002] OLED display panels are widely used because of their advantages such as self-illumination, high brightness, and wide viewing angles. However, since oxygen and moisture are likely to react chemically with OLED materials, resulting in the failure of the display panel, it is necessary to encapsulate the display panel to isolate the oxygen and moisture. Glass paste (Frit) can better isolate oxygen and moisture, so in the process of manufacturing OLED display panels, Frit glue is often used for encapsulation to isolate oxygen and moisture. [0003] At present, in the display panel industry of mobile devices (such as mobile phones, tablet computers, etc.), it is a mainstream trend to ensure that the size of the light-emitting area of ​​the display panel remains unchanged, and to reduce the width of the frame to achie...
