Abstract

The invention discloses a self-luminescent display screen and a manufacturing method thereof, belonging to the technical field of display. A self-luminescent display screen has a display area and a non-display area in a closed ring shape around the display area. The self-luminescent display screen includes a substrate, and a self-luminescent device and an encapsulation layer sequentially arrangedon the substrate. The telescopic retaining wall structure is arranged around the display area in a closed ring shape, and the encapsulation layer arranged in the non-display area is parallel to one side of the substrate, the encapsulation layer is broken in the target area, and the target area is located in the area where the telescopic retaining wall structure is orthogonally projected from the encapsulation layer. In the process of laser cutting the mother board of the display screen, even if the high temperature causes the cutting edge of the encapsulation layer to crack, the encapsulationlayer in the non-display area has been broken, the crack cannot extend to the encapsulation layer in the display area, and the encapsulation reliability of the self-luminescence type display screen isimproved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a self-luminous display screen and a manufacturing method thereof. Background technique [0002] At present, in the manufacturing process of self-luminous display screens, self-luminous devices and encapsulation layers are usually sequentially prepared on the base substrate to obtain a display motherboard. The display motherboard includes a plurality of self-luminous display screen, and then cut the display motherboard to obtain a self-luminous display screen. Wherein, the self-luminous device includes an Organic Light-Emitting Diode (Organic Light-Emitting Diode, OLED) device, a Quantum Dot Light-Emitting Diode (Quantum Dot Light-Emitting Diodes, QLED) device, and the like. [0003] In the related art, laser cutting is usually used to cut the motherboard of the display screen to obtain multiple self-illuminating display screens. The cutting process includes: using a laser bea...
