Abstract

The invention belongs to the field of flexible display thin film packaging, and discloses a flexible display electrofluid atomized thin film packaging system and process. The system includes a loading and transferring unit, an electrospray unit, a liquid film detection unit, a curing unit, and a thin film detection unit. The unit is used to prepare the packaging liquid film by electric atomization; the liquid film detection unit is used to detect the overall shape, liquid film thickness, and uniformity of the liquid film thickness of the atomized liquid film; the curing unit adopts various curing methods to cure the liquid film; the thin film The detection unit is used to detect the overall morphology of the cured film, the flatness of the film surface, the overall thickness, the uniformity of the overall thickness, and the porosity of the film surface. The entire system and process of the patent of the present invention can effectively ensure production efficiency, reduce scrap rate, fast production speed, low cost and high precision.

Description

technical field [0001] The invention belongs to the field of flexible display device manufacturing, and more specifically relates to a flexible display electrofluid atomized film packaging system and process. Background technique [0002] Flexible display technology, also known as OLED (Organic Light Emitting Diode) technology, is currently a cutting-edge technology in the display field. Through the exploration and research of new soft display materials, display devices such as display screens can be folded or curled at will, which greatly breaks through the application scenarios and user experience of display products. At the same time, because of its advantages such as self-luminescence, wide viewing angle, high contrast, low power consumption, high response rate, full color, light weight, thin thickness, simple structure, and low cost, OLED brings low power consumption to flexible display devices. , Thin, unbreakable and bendable characteristics, are widely used in smart...
