## Abstract

A flexible display device and a data displaying method thereof are disclosed. The device includes a touch sensor to generate touch events according to touch actions, a flexible sensor to generate a bend signal as one side of the device is bent, a storage unit to store a function table, and a controller to control the components of the device. The function table is configured to define control operations to reproduce currently output contents based on the touch events and the bend events.
