International ClassG09G 003/32AbstractA display apparatus according to our invention comprises a multiplicity of nominally identical smart pixels, a given pixel comprising an organic light emitting diode and an organic or inorganic (e.g., amorphous or polycrystalline Si) pixel FET. The display also comprises drive/compensation circuitry adapted for mitigating or eliminating non-idealities associated with the organic components. Among the non-idealities are variations in mobility and/or threshold voltage of the pixel FET from transistor to transistor, change in mobility and/or threshold voltage with time in a given pixel FET, change over time of the LED characteristics, capacitive signal feed-through through the gate insulator of the pixel FETs by short rise/fall time pulses, poor on-off ratio of the pixel FET, and charge leakage through the gate dielectric. Exemplary drive/compensation circuitry is disclosed.Other References
