A method for operating a plurality of flexible displays to implement an interactive operation among the plurality of flexible displays is provided. The method is used between the plurality of flexible displays and a system control platform. Each flexible display is configured with a plurality of light sensors and a plurality of sensors and a processor. The method includes: quantifying, by each light sensor, a external luminosity value received by each flexible display; quantifying, by each sensor, a sensor-measuring value received by each flexible display; generating and transmitting, by the processor coupled to the light sensors and the sensors, luminosity information and sensor information according to the external luminosity values and the sensor-measuring values; and receiving, by the information platform, the luminosity information and the sensor information, and implements the interactive operation among the plurality of flexible displays between the plurality of flexible displays according to the sensor information.
