    The flexible AMOLED display has lots of advantages, such as thin structure and flexibility. It can provides better user experience than rigid displays, and attracts more attention from end users. As a key component of flexible display module, flexible touch sensor has also been widely studied on its various forms and touch functions. The capacitive touch sensor technology which is suitable for flexible AMOLED display was introduced. The development status of flexible touch sensor was listed, the flexible touch sensors include Out-cell Touch Sensors (ITO touch sensor, metal mesh touch sensor, SNW touch sensor) and On-cell Touch Sensor which is integrated with flexible AMOLED display. The development of On-cell Touch Sensor accelerates the commercialization of foldable displays, because it has better performance in flexibility. The advantages and challenges of On-cell Touch Sensor were introduced, and the development of touch solution for different size of flexible AMOLED displays was discussed.
