Abstract
The invention provides a method for preparing a patterned film layer, comprising the following steps: providing a substrate, a coating liquid and a coating device, the coating device includes one or more coating components, and one or more coating components Connected controller; add the coating liquid to the coating component, and control the coating component to move on the substrate according to the preset pattern through the controller, so that the coating liquid in the coating component is coated according to the preset pattern to the On the substrate, a patterned film layer is obtained. The preparation method provided by the present invention adopts a brand-new preparation process of the patterned film layer, and the controller controls the coating component to move on the substrate according to the preset pattern, and only one step of operation is required to finally obtain the patterned film layer . The preparation method of the present invention can replace the traditional yellow light process, greatly avoids material waste, reduces cost and risk, and improves the preparation efficiency and product yield of the patterned film layer.
Description
technical field [0001] The invention belongs to the field of display technology, and in particular relates to a method for preparing a patterned film layer and a coating device. Background technique [0002] OLED is considered to be the most potential display technology due to its advantages of high color gamut, high contrast ratio, wide viewing angle and uniform color. In the OLED display technology, the formation of pixels in the display panel and the formation of various patterned film layers are key technologies in the OLED display technology. Now, in the preparation of the patterned film layer, the whole surface is usually formed first, and then the pattern is formed by yellow light processes such as photoresist coating, exposure, development, etching and stripping, but this method has higher risks. The efficiency of production is low, it will cause waste of materials, increase the cost of products, and the yield rate of products cannot be controlled. [0003] At pres...
