Abstract

The invention provides extinction solder resist ink for a PCB of an LED display screen, which comprises a first component and a second component, wherein the first component comprises 20%-50% of oligomer, 0.5%-15% of photoinitiator, 5%-15% of nano black filler, 10%-30% of matting agent, 0.2%-2% of coupling agent and 10%-30% of solvent; and the second component comprises 20%-40% of epoxy resin, 5%-40% of a functional monomer, 10%-20% of a delustering agent, 0.2%-2% of a coupling agent and 5%-15% of a solvent; the first component and the second component are stored separately and are mixed when in use. The extinction solder resist ink has good solder resist performance and excellent extinction performance, and can effectively improve the problem of inconsistent ink color when the LED display screen is black. The invention further provides a preparation method of an LED display module adopting the extinction solder resist ink and an LED display screen.
