Problems solved by technology
However, at present, display panels are limited by high resolution and narrow borders, and the display area of the panel is relatively close to the cutting line. Under the double influence of laser cutting precision and laser heat radiation, it is easy to cause the manufacturing failure of the display panel or the yield rate is difficult to improve.

The invention provides a display panel mother board, a display panel and a manufacturing method of the display panel. The display panel mother board comprises at least one display unit and a cuttablearea connected to the edge of the display unit. The display unit has a display area and a non-display area connected between the display area and the cuttable area. The cuttable area is provided witha cutting position. The display panel mother board comprises a substrate and a device layer arranged on the substrate, and the device layer comprises a TFT device area corresponding to the display area and an inorganic film layer wrapping the TFT device area. The inorganic film layer covers the non-display area and the cuttable area, hollowed-out patterns are arranged in the non-display area in the thickness direction of the non-display area in an up-and-down penetrating mode, and a groove which is not arranged in a penetrating mode is formed at a cutting position, thereby effectively avoidingthe heat radiation influence of laser cutting, and improving the production yield.
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] OLED (Organic Light-Emitting Diode, organic light-emitting diode), because it has self-illumination, no need for backlight, high contrast, thin thickness, wide viewing angle, fast response speed, can be used for flexible panels, and the operating temperature range It is considered to be an emerging application technology of flat panel displays due to its excellent characteristics such as wide, simple structure and manufacturing process. [0003] The OLED display panel is generally manufactured on a mother board, and then cut and separated to form individual display panel units. At present, laser cutting is mostly used to ensure a smooth and flat cut surface. However, at present, display panels are limited by high resolution and narrow borders, and the display area of ...
