In order to control bending radii of flexible substrates in displays, this paper presents an optimal fast-response sliding-mode control method. Maximum driving voltages are utilized in sliding-mode control based on a linear quadratic estimator. An optimal design for the threshold value and the reaching-law parameter are obtained by using a procedure of the fast-response regulation. Implementing the proposed method, this study measures electrical resistances for different widths of line patterns on polyethylene terephthalate/indium tin oxide substrates up to 11,000 bending times.
► An optimal fast-response sliding-mode control (OFRSMC) method has been developed. ► We have successfully controlled bending radii of flexible substrates by OFRSMC. ► Electrical characteristics of flexible substrates for bending 11,000 times are presented.
