Abstract

A new low-temperature polysilicon thin-film-transistor pixel circuit for 3-D active-matrix organic light-emitting diode (OLED) display and its driving scheme that is based on simultaneous emission at a frame rate of 240 Hz are proposed. The proposed circuit can compensate for the threshold voltage deviation of TFTs and power-line IR-drops. Moreover, the degradation of OLED luminance is reduced using a feedback structure. The measurement results of the relationship between the luminance degradation and the threshold voltage shift of the OLED confirmed the stability of the luminance of the proposed circuit.
