Abstract :
Requirement on thin-film transistors, particularly in terms of current-drive and parameter uniformity, for active-matrix organic light-emitting diode displays, was analyzed. Metal-induced unilaterally crystallized polycrystalline silicon thin-film transistor technology was shown to satisfy such and other demands. Though pixel designs involving more transistors were certainly advantageous, appropriate biasing scheme allowed a simpler and larger aperture-ratio two-transistor design. As a demonstration, active matrices were fabricated and integrated with organic light-emitting diodes to make monochrome video display panels, each consisting of 120 rows and 160 columns
