Production method of pattern color mixing film

Abstract

The invention relates to a production method of a pattern color mixing film. The production method comprises the following preparation steps: step 1, preparing a conductive solution; step 2, coating atransparent film with the conductive solution by using a reverse plate coating roller, wherein the resistance of the coated surface conductor reaches 40-70 [ohm]/square; 3, respectively fixing the positive electrode pattern conducting layer film and the negative electrode pattern conducting layer film on two sides of a liquid crystal coating machine, wherein the positive electrode conducting region and the negative electrode conducting region are oppositely arranged; coating PDLC liquid crystals between the positive electrode pattern conducting layer thin film and the negative electrode pattern conducting layer thin film; and drying and rolling to obtain the pattern color mixing film. The pattern color mixing film prepared by the invention is simple in structure and easy to manufacture; and different reverse coating rollers can be manufactured according to the requirements of customers to obtain pattern toning films with different patterns, and the pattern contour lines are manufactured by printing, so that the patterns are exquisite and fine, and the display effect is good.

Description

technical field [0001] The invention relates to a preparation method of an intelligent PDLC liquid crystal toning film with special patterns or characters. Background technique [0002] PDLC liquid crystal dimming film is formed by mixing nematic liquid crystal and polymer and curing between two transparent conductive films; in the absence of an electric field, the internal liquid crystal presents a disordered orientation state, which will cause light scattering , the toning film presents a milky white opaque state; when the electric field is connected, the molecules of the micron-sized liquid crystal are arranged in an orderly manner under the action of the electric field, and the refractive index of the molecular polymer and the liquid crystal material tend to be consistent, which greatly suppresses light scattering, so that the liquid crystal is tuned The light film is colorless and transparent. [0003] Due to the inherent characteristics of liquid crystal toner film, i...

[0005] At present, the Chinese Patent Publication No. CN110471205A discloses a method for preparing a PDLC liquid crystal dimming film containing nano-silver wire transparent conductive film. The electrode control is formed by the nano-silver wire to control the pattern; however, the arrangement of the silver wire is difficult, and the formed The pattern should not be too complicated, otherwise the verification will affect the routing efficiency

[0006] Chinese Patent Publication No. CN208737145U PDLC liquid crystal dimming film and insulating glass with NX×NY display mode adopts an electrode array to realize fixed-area electrification and fixed-area development, and applies liquid crystal display technology to PDLC liquid crystal dimming film , which greatly expands its application scope; however, this application method has high cost, and is affected by the accuracy of the dot matrix, and the image accuracy is poor, so it is only suitable for displaying text content
