Abstract

The embodiment of the invention provides a manufacturing method of an organic thin film pattern, the organic thin film pattern, an array substrate and a display device, relates to the technical fieldof display, and can solve the problem of a non-uniform thin film caused by coffee ring effect and climbing phenomenon in the prior art. The manufacturing method of the organic thin film pattern comprises the following steps: forming ink droplets in a concave part in a thin film defining layer positioned on a substrate, wherein the ink droplets are a gel solution containing an organic functional material; gelatinizing the ink droplets; and drying the gelled ink droplets to form the organic thin film pattern.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for fabricating an organic thin film pattern, the organic thin film pattern, an array substrate and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) displays have been widely used in computers, mobile phones, etc. Various electronic devices including electronic products. [0003] In the prior art, inkjet printing is generally used in the production of OLED displays to print ink droplets to the openings of the corresponding sub-pixels in the pixel definition layer, and then remove excess solvent through subsequent drying and other processes to form organic light-emitting functional patterns layer. [0004] However, refer to figure 1 , because the side wall of the pixel definition layer Bank near the bottom generally has a certain degree of lyophilicity and has a strong affinity for ink droplets, so that during the drying process, ink...
