Abstract:
1. A dual mode capacitive touch panel, comprising: a sensor substrate; an electrode layer comprising an array of sensor electrodes arranged over the sensor substrate, the array of sensor electrodes including a plurality of drive electrodes and a plurality of sense electrodes, each sensor electrode corresponding to a location on the sensor substrate; a shield layer arranged over and spaced apart from the electrode layer, the shield layer having a predetermined resistance that permits transmission of an electric field at a first frequency and prevents transmission of an electric field at a second frequency, wherein a spacing between the shield layer and the electrode layer is deformable as a result of a force applied to the shield layer due to a user touch; and a controller operatively coupled to the array of sensor electrodes, the controller configured to measure a location of an object relative to the sensor substrate and measure a force applied toward the sensor substrate.
