Display panel mother board, display panel and manufacturing method thereof

Abstract

The invention relates to a display panel mother board. The display panel mother board comprises a plurality of display substrates, wherein each display substrate comprises an array substrate, an organic light-emitting unit and a packaging layer; each array substrate is provided with at least one notching reserved area, each organic light-emitting unit is formed on the corresponding array substrateand is positioned in the area outside the corresponding notching reserved area, each packaging layer is formed on the side, away from the corresponding array substrate, of the corresponding organic light-emitting unit, and each notching reserved area is covered with the corresponding packaging layer; each display substrate also comprises an etching protective layer, and each etching protective layer is formed on the side, away from the corresponding array substrate, of the corresponding packaging layer. Films in the notching reserved areas are removed and notched by using a dry-method etchingtechnology, and display abnormity and poor sensing for notching area edges caused by the damages of films and circuits in the edges of mounting grooves in the cutting process are avoided compared with the utilization of laser cutting or utter wheel cutting in the prior art, so that the production yield of the display panel is improved. The invention also provides a display panel, a manufacturingmethod thereof and a display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel motherboard, a display panel and a manufacturing method thereof. Background technique [0002] In recent years, with the technological development of smart terminal devices and wearable devices, the demand for flat panel displays has become more and more diverse. Organic light-emitting diode displays such as OLED (Organic Light-Emitting Diode, OLED) have self-illumination performance, and compared with liquid crystal displays, they do not need a relatively energy-consuming backlight module, so they have the advantage of being more energy-saving. In addition, compared with traditional flat panel displays, OLED displays have the advantages of being bendable and flexible, and are widely used in smart terminal products such as mobile phones and tablet computers. [0003] Because it is easy to customize the appearance, more and more terminal manufacturers apply it to...
