Introduction
Onlymer® BM is the resin black matrix solution for LCD color filter. It takes the role of shading the light among the color patterns and so enhance the contrast ratio. The characteristics of Onlymer OC are as follows;
ONLYMER®BM series will provide a wide process margin and high OD values as well as high sensitivity in the LCD color filter.
