Problems solved by technology

However, the current flexible display technology is not mature enough. In order to prevent leakage between the gate in the first metal layer and the source and drain in the second metal layer, the existing flexible display panels usually set the first metal layer The thickness of the insulating layer between the second metal layer and the second metal layer is larger than that of other insulating layers, which leads to poorer stress performance of the insulating layer. When the screen is bent, it is more prone to breakage and falling off. cause defective products

Abstract

The present invention provides a flexible AMOLED display panel in which a hollow structure extending downwardly through at least the interlayered insulation layer is formed, starting from the interlayered insulation layer in a region other than the TFT structure; the hollow structure is filled with a planarization layer. Through the utilization of the organic materials in the planarization layer to replace the inorganic materials of the interlayered insulation layer, the gate electrode insulation layer and the buffering layer, it is possible to improve the stress performance of the flexible AMOLED display panel and prevent the breakage and come-off of a screen when the screen is bended; in addition, since the hollow structure is arranged in a region other than the TFT structure, the insulation effect among the gate electrode, the source electrode and the drain electrode in the TFT structure is not compromised.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible AMOLED display panel. Background technique [0002] Flat-panel display devices have many advantages such as thin body, power saving, and no radiation, and have been widely used. Existing flat panel display devices mainly include liquid crystal display devices (Liquid Crystal Display, LCD) and organic light emitting diode display devices (Organic Light Emitting Display, OLED). [0003] Organic light-emitting diode display devices have excellent characteristics such as self-illumination, no need for backlight, high contrast, thin thickness, wide viewing angle, fast response speed, flexible panels, wide operating temperature range, and simple structure and manufacturing process. It is considered as an emerging application technology for the next generation of flat panel displays. OLED display devices can be divided into passive matrix OLED (Passive Matrix OLED, PMOLED)...
