Flexible display panel and manufacturing method thereof

Abstract

The invention provides a manufacturing method of a flexible display panel. The manufacturing method comprises the following steps of providing an array substrate, wherein the array substrate comprisesa semiconductor layer, the flexible display panel is divided into adjacent pixel region and bending region, and the pixel region comprises the semiconductor layer; digging a second groove in the bending region, wherein the second groove forms a stage structure in the array substrate, and the stage structure extends from the interior of the array substrate to a direction opposite to the inner wallof the second groove; filling the second groove with an organic material, and an inwardly concave conical groove is formed in the surface, flush with the array substrate, of the organic material filled in the second groove; and manufacturing a source, a drain and source and drain routing lines on the array substrate, wherein the source and the drain are connected to the semiconductor layer, and the source and drain routing lines cover the conical groove. By virtue of the above-mentioned setting, the bending degree of the source and drain routing lines in the position of the conical groove canbe lowered, thereby effectively relieving the problem of cracking of the source and drain routing lines in the position of the conical groove. The invention also provides the flexible display panel.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a method for manufacturing a flexible display panel and the flexible display panel. Background technique [0002] In the traditional flexible OLED display panel manufacturing process, in order to enhance the bending performance of the display panel, a number of holes are opened on the inorganic layer in the layer structure of the OLED, and organic materials are filled in the holes. The performance is significantly better than that of inorganic materials, thereby improving the bending performance of OLED display panels. [0003] However, when filling organic materials, because the holes opened are deep, organic materials cannot be filled in too deep holes, and a tapered groove will be formed on the outer surface, and the depth of the tapered groove is too deep and the slope is too steep. When the source and drain are routed, the bending angle of the wire at the posit...

Problems solved by technology

[0003] However, when filling organic materials, because the holes opened are deep, organic materials cannot be filled in too deep holes, and a tapered groove will be formed on the outer surface, and the depth of the tapered groove is too deep and the slope is too steep. When the source and drain wires are routed, the bending angle of the wires at the position of the tapered groove is too large, which may easily cause the wires to break
