Abstract

A pressure sensor and a display device are described. The pressure sensor includes a plurality of pressure units. Each of the pressure units includes four resistors having substantially the same resistance value. The four resistors form a Wheatstone bridge. Two resistors of the four resistors form a first resistor group. The other two resistors of the four resistors form a second resistor group. Orthogonal projections of electrodes of the two resistors of each of the resistor groups at least partially overlap in a direction perpendicular to a plane on which the pressure units are located. Extension directions of electrode patterns of the two resistors of each of the resistor groups are different.
