Problems solved by technology

In the existing optical filters, blue glass is generally used as the optical element, which can filter out infrared rays, but its own toughness is poor, and the thickness will be between 2-5mm. For some high-demand products, this thickness is still insufficient. Larger, does not meet the requirements of use, and the surface strength is poor, prone to scratches, therefore, a high-toughness resin filter and its preparation method are needed

Abstract

The invention discloses a high-toughness resin optical filter and a preparation method thereof. The optical filter comprises a substrate, and a modified dispersion resin layer is arranged on the outerside of the base plate; a restoration coating is disposed outside the modified dispersion resin layer; and a coating layer is disposed inside the substrate. According to the present invention, the preparation method is simple, and the prepared optical filter has characteristics of good light transmittance, high infrared ray absorption degree, good strength, good toughness, uniform particle distribution, wear resistance, scratch resistance and corrosion resistance, and can be popularized.

Description

technical field [0001] The invention relates to the technical field of optical filter preparation, in particular to a high-toughness resin optical filter and a preparation method thereof. Background technique [0002] With the development of Thin Film Transistor Liquid Crystal Display (TFT-LCD) technology, its cost has been reduced and its manufacturing process has been further improved, making it a mainstream technology in the field of flat panel display. In the existing optical filters, blue glass is generally used as the optical element, which can filter out infrared rays, but its own toughness is poor, and the thickness will be between 2-5mm. For some high-demand products, this thickness is still insufficient. Larger, does not meet the use requirements, and the surface strength is poor, easy to produce scratches, therefore, a high toughness resin filter and its preparation method are needed. Contents of the invention [0003] The purpose of the present invention is to...
