説明
To display information, flexible displays are a promising device. We present energy methods in conjunction with the calculus of variation to obtain deflections of flexible substrates subject to torque. In addition to analytical derivation, in experiments an electric motor under computer control exerts torque to generate display torsion, whose twist angles are obtained by using both optical encoder measurement and theoretical calculation. Comparisons are made between experimental and theoretical results for PET (polyethylene terephthalate) and PEN (polyethylene naphthalate) polymer substrates. Both experimental and theoretical results show that the required torque due to unit twist angle increases with the twist angle. A larger PET substrate is not as easy to be twisted as smaller one. In addition, a square PET substrate is not as easy to be twisted as rectangular one with the same width.
