Problems solved by technology

When bending, since the flexible display substrate still contains a large number of inorganic layers, these inorganic layers are prone to damage and fracture, which further causes damage and fracture of the conductive wiring in the OLED, causing the performance of the flexible display substrate and display device to decrease or even fail.

Abstract

Disclosed is a flexible display substrate. The flexible display substrate comprises a flexible substrate, and a gate, a source, a drain and multiple conductive wires arranged on the flexible substrate; multiple grooves are formed in each conductive wire in a bending region of the flexible display substrate, so that the damage resistance of the conductive wires is improved in bending; and consequently, the bending resistance effect of the flexible display substrate is improved, and the reliability and service life of the flexible display substrate and a display apparatus are improved and prolonged. The invention also discloses the display apparatus comprising the flexible display substrate and a manufacturing method for the flexible display substrate.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular to a flexible display substrate, a manufacturing method thereof, and a display device. Background technique [0002] Organic light emitting display (Organic Light Emitting Display, OLED) has gradually become the mainstream in the display field due to its excellent performance such as low power consumption, high color saturation, wide viewing angle, thin thickness, and flexibility. Currently, OLEDs are widely used in terminal products such as smartphones, tablets, and televisions. In order to achieve a narrow frame, lead pads are usually fabricated on one side of the substrate, and the OLED is bent with a very small radius. When bending, since the flexible display substrate still contains a large number of inorganic layers, these inorganic layers are prone to damage and fracture, further causing damage and fracture of the conductive wiring in the OLED, causing performa...
