Abstract (en)

[origin: WO0007212A1] A field emission display (10) includes a plurality of spacers (24) attached to a cathode display plate (14) by an adhesive layer (38). The adhesive layer (38) is preferably an electrically conductive, transition-metal sol-gel adhesive. The sol-gel adhesive is formulated to provide an adhesive film (60) having predetermined surface properties, such that the adhesive film (60) can be spread upon a transfer stage (62). The adhesive film (60) possesses sufficient tackiness, such that vertical members (52) can be brought into contact with the adhesive film (60), whereupon a small amount of adhesive adheres to an attachment surface (58) at the end of the vertical members (52). After applying the adhesive, the vertical members (52) are directly attached to a bonding area (66) on display plate (54) by means of a moveable transfer device (40).
