Abstract

The invention provides a display panel and a manufacturing method thereof. The display panel comprises a flexible substrate, a buffer layer, a combined insulating layer, a groove, an organic insulating layer and a first line changing layer. The invention provides a display panel and a manufacturing method thereof. The first line changing layer is disposed on the upper surface of the organic insulating layer and extends to the combined insulating layer. Through holes in the organic insulating layer in the prior art are removed. Therefore, on the other hand, line breakage in the first line changing layer can be reduced; on the other hand, since one side edge line of the first line changing layer is a square waveform, a sawtooth waveform, a triangular waveform, or a sinusoidal waveform, adjacent lines in the first line changing layer can be prevented from being short-circuited, thereby improving the stability of the display panel.

Description

technical field [0001] The invention relates to the display field, in particular to a flexible display panel and a preparation method thereof. Background technique [0002] OLED can be divided into passive matrix (PM-OLED) and active matrix (AM-OLED) two categories. Active matrix display panels include flexible foldable display panels and rigid display panels. The flexible foldable display panel includes a low temperature polycrystalline silicon thin film transistor (LTPS TFT). Among them, the process flow of the flexible folding display panel is 10-15 processes, which is 2-3 more mask processes than the rigid AMOLED display panel. Among them, the flexible foldable AMOLED LTPS display panel includes a display area and a non-display area, and the extra process is mainly to use photolithography and dry etching (Dry) process for the inorganic film with poor stress and poor flexibility in the bending area. Etching, and then filling with organic flexible PI material (O-ILD), w...
