Abstract

A method of fabricating an organic electronic device by ink- jet printing into channels, comprises using a print head (606) to deposit an ink into a channel, wherein the print, head travels in a direction substantially transverse, perpendicular, or orthogonal to the length of the channel. The channel may be a single or dual bank (603,604,605) channel of 90 & mu;m pitch which may be defined by either a positive or negative photo-resist material. The ink may be an organic conducting material such as PEDOT, or PEDOTPSS. The ink may also be combined with a solvent such as toluene or xylene for example. The method can also be used to fabricate active or passive matrix displays. The print head may also be further rotated by an angle of & theta; which allows the reduction of the printer's dot pitch by a factor of cos & theta.
