Title:
METHOD OF ELECTROSTATIC DEPOSITION
Document Type and Number:
WIPO Patent Application WO2004028707
Kind Code:
A3
Abstract:
A process for the electrostatic deposition, in particular of LCD color filters (9) or spacer material (15) on a substrate (1) of a display, involves the successive electrostatic deposition of the red, green and blue color material (8) and the black matrix material (14) or spacer material. The aerosolized material having a unipolar charge in the deposition chamber experiences an electrostatic force of controlled magnitude that is directed (preferably antigravitationally) towards the substrate surface by means of an (externally) applied electrostatic field.
