Problems solved by technology
Due to the use of a large number of inorganic processes in the devices made on the surface of flexible substrates, during frequent bending, the bending area is affected by the stress on the front and back sides, and its inorganic layer is more likely to break, resulting in deterioration or even damage to the device function.
After the function of the device deteriorates, the display effect and product life will be greatly affected

The invention discloses a flexible display substrate, comprising a flexible substrate, at least one groove is arranged in a bending area of the flexible substrate; the opening of the groove is oriented opposite to the light-emitting direction of the flexible display substrate. The invention also discloses a manufacturing method of a flexible display substrate, a flexible display device and a carrier substrate. The flexible display substrate and its manufacturing method, the flexible display device and the carrier substrate provided by the present invention can reduce the damage to the device itself on the flexible display substrate caused by stress during bending.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a flexible display substrate and a manufacturing method thereof, a flexible display device, and a carrier substrate. Background technique [0002] An Organic Light Emitting Diode (OLED for short) has the property of self-luminescence, and the OLED will emit light when an electric current passes through it. With the rapid progress of display technology, semiconductor element technology, which is the core of the display device, has also been greatly improved. For existing display devices, organic light-emitting diodes, as a current-mode light-emitting device, are increasingly being used because of their characteristics such as self-illumination, fast response, wide viewing angle, and the ability to be fabricated on flexible substrates. It is used in the field of high-performance display. [0003] Organic Electroluminescent Display (Organic Electroluminescent Display), wi...
