Abstract
The present disclosure provides a force sensor, a display panel, and a force detection method. The force sensor includes a first input terminal, a second input terminal, a first output terminal, and a second output terminal. A first resistor is connected between the first input terminal and the first output terminal. A first transistor and a second transistor are connected in parallel between the first output terminal and the second input terminal. A third transistor and a fourth transistor are connected in parallel between the second input terminal and the second output terminal. A further first resistor is connected between the second output terminal and the first input terminal. An equivalent resistance of the first transistor is equal to that of the fourth transistor, and an equivalent resistance of the second transistor is equal to that of the third transistor.
