Apple is testing 1.5-inch OLED touchscreens for use in its upcoming smartwatch, claims Taiwanese publication the Economic Daily News. Apple is in fact said to have tried 1.8-inch screens, but judged that they were too big. The 1.5-inch panels are reportedly being manufactured by Taiwan's RiTdisplay, and use one-glass-solution touch sensors, which should allow Apple to keep the watch thin.
