ELECTRONIC DEVICE COMPRISING SENSOR AND ONE OR MORE CONDUCTIVE LAYERS TO BE DRIVEN USING SIGNAL FROM SENSOR

摘要

The present invention relates to an electronic device capable of enhancing the sensing performance of a pressure sensor, and the electronic device according to an embodiment comprises: a touchscreen display comprising a display panel and a first conductive layer which is disposed under the display panel; and a pressure sensor disposed under the first conductive layer, wherein the pressure sensor comprises a first electrode layer, a second electrode layer, a dielectric layer disposed between the first electrode layer and the second electrode layer and having elasticity, and a second conductive layer disposed between the first electrode layer and the first conductive layer, and comprises a sensor driving circuit electrically connected to the first electrode layer, the second electrode layer, and the second conductive layer, and the sensor driving circuit may be configured to drive at least a part of the first electrode layer by using a first signal, drive the second conductive layer by using a second signal related to the first signal, and detect a change in pressure input to the electronic device, at least on the basis of a change in a signal value resulting from a change in the distance between the first electrode layer and the second electrode layer. Other various embodiments may be further included.
