Abstract:
A pressure-sensing circuit, a method for driving the pressure-sensing circuit and a display device are provided. The pressure-sensing circuit includes pressure-sensing gating lines arranged in rows, pressure-sensing reading lines arranged in columns, piezoresistance sensing circuits arranged in N rows and M columns, a pressure-sensing sub-circuit, a current input control circuit, and a current supply circuit for supplying a pressure-sensing current, where each of N and M is an integer greater than 1. The current input control circuit includes N current input control sub-circuits. The pressure-sensing sub-circuit is connected to each of the pressure-sensing reading lines and configured to perform a pressure-sensing operation in accordance with a voltage signal acquired from each of the pressure-sensing reading lines.
