Abstract

The invention provides a flexible display panel and a manufacturing method thereof. The flexible display panel is provided with a display area, a non-display area and a bending area arranged between the display area and the non-display area. The flexible display panel comprises a substrate base plate and at least one signal trace arranged on the substrate base plate. Each signal trace comprises atleast two metal layers and an insulating layer arranged between the two adjacent metal layers in the bending area; orthographic projections of the at least two metal layers on the substrate base plate are not overlapped with each other, and the insulating layer is made of a low-modulus organic material, so that the increase of rigidity can be effectively relieved, the signal trace is prevented from being broken, impedance is reduced, and a narrow bezel of the flexible display panel is favorably realized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible display panel and a manufacturing method thereof. Background technique [0002] With the rapid development of the display industry, flexible display technology has advanced by leaps and bounds in recent years. While the pixel density (PixelsPer Inch, PPI) has increased rapidly, narrow frame technology has also developed by leaps and bounds. Flexible display technology can be bent by Pad ( pad bending) technology to reduce the size of the lower bezel. With the continuous improvement of consumer demand for display products and the continuous development of narrow bezel technology, full-screen bezel-less display products have emerged. [0003] However, in the pursuit of narrow bezel technology, when pad bending is implemented, since the bending radius of the bending area is getting smaller and smaller, it is easy to cause disconnection of signal lines and high impedance,...
