Abstract

The invention provides a method for improving the color difference of LED printed circuit boards, which is characterized by comprising the following steps: S1, color difference analysis; and S2, colordifference improvement. The color difference improvement process includes the following sub-steps: S21, increasing the ink collecting frequency for the first time; S22, increasing the ink collectingfrequency for the second time; and S23, improving the uniformity of the ink and ensuring the viscosity of the ink. Through a large number of creative experiments, the inventor has found a method for improving the color difference of LED printed circuit boards, which can ensure the viscosity and uniformity of ink in the screen printing process and better ensure the color difference consistency of finished products. The problem of 'mosaic' effect in the splicing of LED display screens, especially indoor bare display screens, is solved.

Description

technical field [0001] The invention belongs to the technical field of LED circuit board processing, and in particular relates to a method for improving the color difference of an LED printed circuit board. Background technique [0002] Most of the existing PCB printed circuit boards are presented in the hands of customers in individual form, and even in the form of a complete package after packaging, there is no special requirement for slight color difference in appearance. The LED display is spliced ​​and assembled with hundreds of small boards, and is presented to customers in the form of bare PCB background color, which is prone to "mosaic" visual effects. Contents of the invention [0003] In view of this, the present invention provides a method for improving the chromatic aberration of LED printed circuit boards. The present invention effectively solves the problem of "mosaic" effect on LED display screens, especially the splicing of indoor bare board display scr...
