Embodiment Construction

[0021] Taking the coating of a diffusion film on the light guide plate substrate as an example, the method flow chart of this method is as follows figure 1 As shown, the specific steps are: the first step, ultrasonic cleaning, the TFT-LCD glass substrate to be cleaned is sent to the ultrasonic cleaning device through the input conveyor, the ultrasonic frequency is controlled at 28KHz-40KHz, the handling speed is 3m / min, pure The water flow rate is 30L / min. At this time, the cleaning effect is the best, and then dry it with a drying oven at about 60°C. In the second step, pre-coating, a scratch-resistant layer composed of a scratch-resistant material is coated on the glass substrate, and the coating is carried out by gravure printing. The thickness of the scratch-resistant layer is controlled between 1um-2um. The third step is drying. After the pre-coating is completed, use a drying oven to dry at 55-70°C. The fourth step is to coat the diffusion film. First, prepare the coati...

Abstract

The invention discloses a method for coating a diffusion film coating and relates to the field of optical thin films of the plane display technology. The method comprises steps of cleaning and drying a substrate, coating an anti-scraping layer which is made of an anti-scraping layer material in advance, drying the anti-scraping layer, coating the diffusion film coating to the surface of the anti-scraping layer, and conducting infrared ray drying and drying. The method is a novel coating method and the good diffusion film coating can be prepared.

Description

technical field [0001] The invention relates to the field of optical thin films in the flat panel display technology, in particular to a coating method route for coating a diffusion film coating on a substrate in the flat panel display technology. Background technique [0002] The three key areas of modern high technology are materials, energy and information science. They constantly put forward new performance requirements for material materials. In recent years, thin film technology has made rapid progress with the development of high technology. Due to the mutual advancement and combination of coating technology, thin film materials, and surface physics, thin film technology has become a comprehensive applied science and a new focus of future industrial development. In some developed countries, thin film technology has been fully promoted and applied. In addition to the development of optical thin film integrated circuit films, liquid crystal display films, magnetic ...
