    Abstract: The invention provides a display device (26) including a plurality of discrete display segments (2). Each display segment (2) is provided with a drive circuit for driving the display elements arranged within the display area. The display device may be provided either as a passive, active or direct pixel addressed array. By interconnecting a number of display segments, a large area display can be achieved without the requirement for long electrodes. This reduces the electrical resistance and parasitic capacitance of the addressing electrodes, enabling the display to provide improved luminance in a displayed image and to operate at higher speeds, providing improved resolution. An active matrix addressing scheme can also be implemented using relatively low mobility organic thin film transistors.

    Abstract: The invention provides a method and apparatus for depositing soluble materials on flexible substrates. The apparatus comprises a drum, which is rotatable about its longitudinal axis, and an inkjet print head disposed over the drum and adapted to be moved relative to the drum in a direction substantially parallel to longitudinal axis of the drum. A substrate is mounted on the drum by vacuum means and a line of droplets of a solution of the selected material is deposited by the print head, which remains stationary as the drum is rotated. The print head is then moved relative to the drum, in the direction substantially parallel to longitudinal axis of the drum, prior to deposition of subsequent lines. In this way, electrical devices can be built up on the substrate and a large scale flexible display device can be fabricated.

    Abstract: A conductive pattern is formed on a substrate, without the use of photolithography, by inkjet printing a confining liquid 15,16 and then inkjet printing a target liquid 17 which is immiscible with the confining material. The liquids are then dried to produce a solid deposit from the target liquid. The resulting conductive line 18 is narrower than a conventional inkjet printed strip. The target liquid 17 may contain a suspension of an electrically conductive solid deposit, such as a conductive polymer or a metal. The confining liquids 15,16 may comprise water or a polar organic solvent. The method is applicable to TFT electrodes and data lines used in active matrix display panels. The channel length of the TFTs can be 20 žm. Since narrow gate electrodes can be printed, gate-source/drain overlap and hence parasitic capacitance is reduced. The method may be used for printing semiconductor material, such as the channel region of a transistor, and also for forming optical waveguides.
