Abstract
(EN)
Disclosed are a flexible organic light-emitting diode (OLED) display substrate and a method for manufacturing same, wherein the flexible organic light-emitting diode (OLED) display substrate comprises a display region (1), a non-display region (2) and a bending allowable region (3) for connecting the display region (1) to the non-display region (2), characterized in that multiple liquid-state conductive circuits (4) spaced apart from each other are arranged in the bending allowable region (3), any one of the liquid-state conductive circuits (4) comprises a circuit flow channel (41) arranged in the bending allowable region (3) and a metal wire portion (42) for connecting two ends of the circuit flow channel (41), and an encapsulation layer (6) is arranged on the circuit flow channel (41) to store a liquid-state conductive material (5), with the liquid-state conductive material (5) being sealed in the circuit flow channel (41). Accordingly, the liquid-state conductive circuits (4) can significantly improve the yield of the bending allowable region (3) and eliminate the problem of wire breakage tending to occur to the existing bending allowable region during bending.
