Abstract: We have developed a 1.8-inch QVGA AMOLED display with the world's highest pixel density of 223ppi by using high precision shadow mask evaporation method, a hybrid emission structure, and a new time division control (TDC) driving method which make it possible to realize high density AMOLED display. From the first design, we have confirmed the suitability of the new driving method and proved the possibility for high-resolution AMOLED displays.

An 8-bit cascaded-dividing DAC that can operate at a low power supply voltage is proposed. Occupying less than one eleventh of the chip area of a conventional binary-weighted DAC with an equivalent resolution, the proposed DAC features a low operation voltage of 2 V with a good DNL and INL of less than 0.15 LSB. The proposed DAC is expected to be adequate for current-driving AMOLED drivers that have very demanding requirements of a narrow channel pitch as well as high linearity and resolution for the data channel DACs.
