  • Patent number: 7560133
    Abstract: A patterning method comprises selectively depositing droplets of a first material solvent solution onto a layer of a second material. The solvent is chosen to dissolve both materials, which are selected so as to exhibit phase separation upon the removal of the solution to provide domains of the first material embedded in and extending through the second material. By selection of appropriate materials the patterning method may be used, for example, to fabricate light emitting devices, optical color filters, or vertical interconnects in electronic devices.

  • Patent number: 7468580
    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.
