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.

Claim (Index 8):
A method for driving the pressure-sensing circuit according to  claim 1 , comprising:\n providing, by the current supply circuit, the pressure-sensing current; applying a second current to the pressure-sensing gating lines in N rows in a time-division manner; in the case that the second current is applied to the pressure-sensing gating line in the n th  row, controlling, by the switching circuit in the n th  row and the m th  column, the second end of the piezoresistance sensor in the n th  row and the m th  column to be electrically connected to the pressure-sensing reading line in the (m+1) th  column, and controlling, by the switching circuit in the n th  row and an M th  column, the second end of the piezoresistance sensor in the n th  row and the M th  column to be electrically connected to the first level end to enable the piezoresistance sensors in the n th  row to be connected in series with each other, and controlling, by an n th  input control circuit, the current supply circuit to be electrically connected to the first end of the piezoresistance sensor in the n th  row and the first column to enable the pressure-sensing current supplied by the current supply circuit to flow to the first end of the piezoresistance sensor in the n th  row and the first column, to enable the pressure-sensing current to flow to the first level end through the piezoresi stance sensors in the n th  row connected in series with each other, where each of the N and M is the integer greater than 1, n is the positive integer smaller than or equal to N, and m+1 is the positive integer smaller than or equal to M; and acquiring, by the pressure-sensing sub-circuit, the voltage signal from each of the pressure-sensing reading lines, and performing the pressure-sensing operation in accordance with the voltage signal.
