Abstract EN

We propose a new pixel design for the active matrix organic light-emitting diode (AMOLED) using low-temperature polycrystalline silicon thin-film transistors (LTPS-TFTs).

The proposed pixel is composed of four switching TFTs, one driving TFT (DTFT), and one capacitor.

The simulation results are performed by AIM-SPICE software.

The error rate of OLED output current with VTH (threshold voltage) variation (0.3 V) and Vdd power line drop by 1 V are improved to about 1.67% and 15%, respectively.

Thus, the proposed pixel circuit can successfully overcome drawbacks suffered from DTFT threshold voltage deviation and IR-drop on power line.
