ULTRA THIN ORGANIC BLACK MATRIX

摘要

An organic black matrix having high resistivity (~10 11 ohm/square), high optical density (~ 2.0) at ultra thin film thicknesses (~ 1.0 microns) for improved STN and TFT pixel display applications is made possible by combining polyimideldye solutions and mixed metal oxide pigment dispersions at a weight/weight ratio of dye to pigment of 1:15 to 3:15. The need for low resistivity carbon black, as a replacement for sputtered chrome, is negated.
