Structure of the AM OLED driver circuit design and layout.

(a) Schematic diagram of AM OLED display design based on a 2T1C single unit circuit, consisting of one ST, one DT, one C_S and one OLED pixel. (b) Optical image of a single AM OLED display unit. The total area of the single unit is 820 × 820 μm² including an OLED pixel area of 480 × 480 μm². (c) A schematic cross-sectional perspective view of the single AM OLED display unit fabricated on a quartz substrate with CVD-grown SWNT network as the active channel, patterned Ti/Au source and drain electrodes, Si₃N₄ gate dielectric, Ti/Au top-gate electrode, integrated green OLED and a SiO₂ passivation layer.
