Abstract

The invention discloses a flexible display substrate, comprising a flexible substrate and wires. The flexible substrate includes a bendable region in which the wires are arranged. The bendable regionincludes at least one through hole; the wires include a first metal wire and a second metal wire; the first metal wire and the second metal wire are electrically connected at the edge of the bendableregion through the at least one through holes. The invention also discloses an OLED (organic LED) display device having the flexible display substrate.

Description

technical field [0001] The present invention relates to a flexible display substrate, in particular to a flexible display substrate for an organic light emitting diode (OLED) display device. Background technique [0002] Organic light-emitting diode display panels have the characteristics of high contrast, wide color gamut, low power consumption, and foldability. In order to make the organic light-emitting tube display device achieve a narrow frame, it is necessary to bend the lower frame of the flexible substrate to the rear of the flexible display substrate. During the bending process of the flexible substrate, the metal wiring used for data signal transmission is prone to cracks or even breaks, resulting in the inability to transmit the signal line. Therefore, it is necessary to improve the configuration of the metal traces in the bending area of ​​the flexible substrate, so as to solve the problems existing in the prior art. Contents of the invention [0003] The pre...
