An AMOLED LTPS Pixel Circuit Compensating for Threshold Voltage Variations, OLED Degradation, and IR Drop

Student Late-News

Description:

We proposed AMOLED LTPS pixel circuit compensating for variations in threshold voltage(VTH), OLED degradation, and IR drop. The proposed circuit is composed of six TFTs and two capacitors. From the simulation results, the maximum OLED current error rates are 6.76%, 12%, and 5.89%, when the VTH shift is -1 V, the OLED stress time is 40,000 s, and the ELVDD reduction is 10%, respectively.
