Abstract
A display integrated pressure sensor is described. In an example, a device comprises: a display including a plurality of layers; a layer of pressure sensitive material having particles; conductivity of the pressure sensitive material is configured to change when the layer experiences deformation; a layer of conductor lines configured to detect the change of the conductivity of the pressure sensitive material; the layer of conductor lines includes a plurality of contacting points with the pressure sensitive material; the layer of pressure sensitive material and the conductor lines are configured to be integrated within the display. In other examples, a manufacturing method and a display module are discussed along with the features of the device.
