Paper Abstract

We succeeded in the mass production of the 3.8-inch Half-VGA AM-OLED display, which is the largest one in the commercialized OLED displays. A new pixel circuit and a driving method for Low Temperature Poly-Si (LTPS) TFT were developed. The new pixel circuit and driving method can compensate not only the Vth variations but also the mobility variations of LTPS TFT. Consequently, we can achieve good pixel-to-pixel luminance uniformity.
