Abstract :
Organic technology is having some limitations like threshold voltage variation and mobility degradation of the organic thin film transistors and the organic light emitting diode luminance degradation. In this paper, a voltage programming pixel circuit for active-matrix OLED display is investigated. The circuit is compensating for the OTFT threshold voltage variation and mobility degradation. Compensation for the OLED luminance degradation is also provided. The circuit is studied and simulated using PSPICE to verify the results.
