Samsung SDI has developed a full color 5.0″ WVGA AMOLED display using top emission structure with a super fine pitch of 0.1365 mm 186 ppi, the worlds highest density OLED display ever reported to date. Scan driver circuits and demux circuits were integrated within the display panel, using low temperature poly-Si TFT CMOS technologies, and data driver circuits were mounted using COG IC. Peak luminescence was greater than 300 cd/ with power consumption of 500 mW with 30% of the pixels on.

We have developed a 1.8-inch QVGA AMOLED display with the worlds 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.
