Abstract
A pressure sensor and a manufacturing method thereof are provided. The pressure sensor includes a thin-film transistor (TFT) array and a pressure-sensitive layer covering the TFT array. The pressure-sensitive layer includes a plurality of insulating layers and one of one-directional materials arranged on the same plane and two-directional materials. The insulating layers and the one- or two-directional materials are alternately stacked so as to effectively enhance pressure resolution.
