1. A flexible display, comprising:
a first flat region, a second flat region, and a folding region between the first flat region and the second flat region, wherein a second surface of the second flat region extends from a folding surface of the folding region and wherein a first surface of the first flat region extends from the folding surface of the folding region; and
a plurality of different sensors configured to output sensing signals to measure a folding angle between the first surface of the first flat region and the second surface of the second flat region,
wherein the plurality of different sensors are operationally responsive to dissimilar stimuli.
