Abstract

A force sensor device, which includes a force sensing layer, is provided, in which a heat treatment layer is disposed on one side of the force sensing layer, and a thermal conductivity of the heat treatment layer is greater than or equal to 200. An OLED display device includes an OLED layer and a CPU element, in which the force sensor device is disposed between the OLED layer and the CPU element. A heat treatment layer is disposed on at least one side of the force sensor device and the force sensing layer of the OLED display device. Heat distribution is relatively uniform through the heat treatment layer, so that a temperature gradient on the force sensing layer may be effectively decreased, the temperature noise in the press force detection may be decreased, and accuracy of pressure detection may be increased.
