Abstract: A display panel and a display device reduces the adverse effects on touch function and display function caused by high heat generation of a force-sensing sensor. The display panel includes, in part, a force sensing sensor, an amplification circuit and a drive chip. The force-sensing sensor includes a first input, a second input, a first output and a second output. The amplification circuit is associated with the force-sensing sensor and includes a first amplification input, a second amplification input and at least one amplification output, wherein the first amplification input of the amplification circuit is coupled to the first output of the force-sensing sensor and the second amplification input of the amplification circuit is coupled to the second output of the force-sensing sensor. The drive chip is coupled to the amplification output of the amplification circuit.
