FLEXIBLE DISPLAY DEVICE AND DRIVING METHOD THEREOF

摘要

A flexible display device includes a flexible display panel to generate an image and a bending detection screen to detect a bending angle and a bending position. The bending detection screen includes an angle detection sensor and a position detection sensor. The angle detection sensor includes a material with a resistance that changes in correspondence to an intensity of an applied stress. The angle detection sensor has an area per unit length that is substantially constant on a base surface. The position detection sensor includes a material with a resistance that changes in correspondence to an intensity of the applied stress. The position detection sensor has an area per unit length that increases along a length direction on the base surface. Signal lines are connected to the angle and position detection sensors.
