Recently, flexible AMOLED display has attracted a quite attention, owing to OLED's inherent flexibility that LCD display can't match. To better realize flexible AMOLED display applications, for examples, in flexible smartphone and flexible tablet, there is a need to develop the corresponding flexible touch sensor technology. In this presentation, we will review key technical requirements for flexible touch sensor, including the choice of transparent conductive films, patterning process, folding ability, etc., and will present our latest development on flexible and foldable touch sensors, that possess the following characteristics, the out‐folding ability of 100,000 times at a coverture of 3mm, touch accuracy, touch sensitivity, and touch linearity. And moreover, we will present the results of the touch sensor‐integrated flexible and foldable AMOLED display.
