Advanced power structure for enhanced optical performance of AMOLED displays at low luminance levels.

ABSTRACT: To improve the image quality of active-matrix organic light-emitting diode (AMOLED) displays at low luminance levels, a novel power structure is proposed. Its effectiveness was validated by fabricating a 13-inch AMOLED panel with a tandem OLED and evaluating its optical performance. Compared to the conventional structure, the proposed structure reduced panel luminance deviation by 12% and color deviation by 41%, while also achieving a 41% reduction in hysteresis-induced color shift. As the temperature compensation capability was enhanced, luminance and color inconsistencies were minimized. By achieving these improvements, the proposed structure effectively addresses a key commercialization challenge for high-efficiency AMOLED technologies. While high-efficiency technologies enable high bri
