P‐31: Pixel Circuit with Backgate Feedback for Deep and Rich Black Expressions on Light‐Emitting Display

A Pixel Circuit for light‐emitting display is presented. The circuit improves controllability of emission current by a feedback network composed of backgate of the drive transistor. The effect is adjusted by the capacitance ratio of the topgate insulator to the backgate insulator and superimposed wh...

Zusammenfassung:A Pixel Circuit for light‐emitting display is presented. The circuit improves controllability of emission current by a feedback network composed of backgate of the drive transistor. The effect is adjusted by the capacitance ratio of the topgate insulator to the backgate insulator and superimposed when the networks are connected in series.
