Display device
View Patent ↗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.
