METHOD FOR PRODUCING ELECTROPHORETIC FLAT PANELS WITH DOUBLE ANODE

摘要

There is disclosed methods for fabricating electrophoretic displays (10). Essentially the methods employ selective materials such as different metals (15, 18, 19, 20) which are capable of being etched by different etchants. In this manner, a laminate is provided to form a grid matrix which is insulated from a cathode matrix (41, 42, 43, 44) which grid matrix is also insulated from a second anode matrix (54, 55). The entire display utilizes a local or second anode and a remote anode (28) to further control pigment particle migration. The display (10) is fabricated by two methods both of which employ selective etching of the parallel line type of display electrodes which constitute a cathode, a grid and a local anode.
