We produce flexible printing plates specially designed for alignment film printing on liquid crystal panels. Tiny concave-convex patterns (halftone dots) are formed on the plate surface to maintain uniform ink distribution, enabling high-quality thin-film printing.
It is mainly adopted for printing alignment films (PI films) of STN, C-STN and TFT-grade LCD products. It can print PI films that are thinner, more uniform and with higher dimensional precision, making it the optimal tool for alignment film printing in the LCD industry at present.
