An AMOLED AC-Biased Pixel Design Compensating the Threshold Voltage and Drop
Figure 6
Signal lines (Scan1, reverse bias, and ) of proposed pixel circuit at = 1 V and the anode voltage of OLED with varied threshold voltage of DTFT ( = −0.33 V, 0 V, and +0.33 V), the insert figure clearly shows of OLED anode voltage under threshold voltage variation of DTFT, and the error rate of OLED is below 0.7%.
