Light-transmitting color diaphragm, manufacturing method thereof and capacitive touch color diaphragm

Abstract

The invention relates to a light-transmitting color diaphragm which comprises a color film base material PET layer, a weak solvent layer, a color printing ink layer used for displaying patterns and a printing white layer, the color printing ink layer is located on the back face of the color film base material PET layer, and the weak solvent layer is arranged between the color film base material PET layer and the color printing ink layer. The color printing ink layer is fixed on the back surface of the color film base material PET layer through the weak solvent layer, and the printing white layer is arranged on the color printing ink layer. A screen does not need to be manufactured when the colorful pattern is manufactured, screen expenditure of traditional project development is directly saved, resources are saved, material cost is saved, the pattern is directly formed by using high-definition photo equipment and a micro-spraying process, the screen does not need to be assembled and disassembled for overprinting one by one, the problem of complex production procedures is solved, production efficiency is improved, furthermore, the labor cost is further saved, and color combination between patterns does not need to be subjected to color register printing and does not need to be subjected to tolerance.

Description

technical field [0001] The invention relates to a light-transmitting color film, a manufacturing method thereof, and a capacitive touch color film. Background technique [0002] Capacitive touch diaphragm, as the name implies, is a way to realize human-computer interaction through the principle of capacitive touch. Capacitive touch diaphragm includes light-transmitting color diaphragm and capacitive touch diaphragm. The existing capacitive touch diaphragm, basically They are all black / white products. Capacitive touch diaphragms are widely used in various home appliances, gradually replacing traditional spring and resistive (IO on-off) membrane switches. [0003] The light-transmitting color film is a product made of PET as the base material and the process of screen printing; if there are multiple colors in the general printing process, a screen needs to be opened for each color to print the required pattern work; the operation process is very complicated; and each color al...

AI Technical Summary

Problems solved by technology

[0003] The light-transmitting color film is a product made of PET as the base material and the process of screen printing; if there are multiple colors in the general printing process, a screen needs to be opened for each color to print the required pattern work; the operation process is very complicated; and each color also needs to be designed to compensate for the process tolerance, so as to avoid product cross-color and lead to poor product production

[0004] The screen printing process is completed by making film negatives of each pattern and color, making a screen through the exposure process, making the required pattern on the screen, and printing again and again; the production process is very complicated. , and each color also needs to be compensated for the tolerance of the process design
