Abstract :
We devised a 6Tr+2C pixel circuit having a threshold voltage compensation function for large-sized OLED displays, and fabricated a 13.5-inch quarter high definition (qHD) OLED display using the pixel. The display device has bottom-emission white tandem OLEDs and a color-filter-on-array structure. The scan driver is integrated on glass.
