Abstract

The present invention provides a flexible display panel and a manufacturing method thereof. The flexible display panel comprises a bending area, the bending area is provided with data signal lines. The at least one data signal line comprises at least one metal layer and at least one stress buffer area internally provided with stress relieving members. The data signal lines in the bending area areprovided with the stress relieving members to reduce the bending stress suffered by the data signal lines when the data signal lines are bent, reduce the impedance of the data signal lines and effectively improve the technical problem that the signal lines are broken and cannot perform signal transmission after the data signal lines are bent so as to improve the service life of the flexible display panel.

Description

technical field [0001] The present application relates to the display field, in particular to a flexible display panel and a manufacturing method thereof. Background technique [0002] With the development of technology in the display industry, users have higher and higher requirements for the appearance design of the display panel, such as the design of a narrow frame. [0003] The lower frame of the display panel of the existing mobile phone generally adopts COF (Chip on FPC) or COP (Chip on Pi) technology to set the position of the driver chip, so that the distance between the lower frame of the display panel is smaller, but the process is difficult and the cost is high . The bending area of ​​the display panel includes metal wires for signal transmission, and when the bending rate of the panel reaches a certain value, the metal wires are prone to cracks or even break, resulting in the inability of the display panel to perform signal transmission. [0004] Therefore, th...
