PROJECT TITLE :

Novel LTPS-TFT Pixel Circuit with OLED Luminance Compensation for 3D AMOLED Displays

ABSTRACT:

A completely unique low-temperature polycrystalline-silicon thin-film-transistor pixel circuit for 3D active-matrix organic light-emitting diode (AMOLED) displays is presented in this work. The proposed pixel circuit employs high frame rate (240 Hz) emission driving theme and solely desires 3.5 μs for input knowledge amount. So, 3D AMOLED displays will be realized below high speed operations. The simulation results demonstrate excellent stability in the proposed pixel circuit. The relative current error rate is only 0.967% under the edge voltage deviation ( ΔVTH_DTFT = ± 0.thirty three V) of driving TFT. With an OLED threshold voltage detecting architecture, the OLED current will be increased with the increased OLED threshold voltage to compensate for the OLED luminance degradation. The proposed pixel circuit will so effectively compensate for the DTFT threshold voltage shift and OLED electrical degradation at the identical time.
