— Data driving techniques and circuits to enhance the image quality of the 0.4-inch diagonal VGA AMOLED on silicon substrate have been proposed. The uniformity of a displayed image can be severely degraded by the random offset voltages of the data drivers. The color shift due to the differential OLED material aging is another well-known concern. To(More)
SUMMARY Oxide material can make transparent devices with transparent electrodes. We developed a transparent oscillator and rectifier circuits with oxide TFTs. The source/drain and gate electrodes were made by indium thin oxide (ITO), and active layer made by transparent material of IGZO (Indium Gallium Zinc Oxide) on a glass substrate. The RC os-cillator(More)
