    摘要: An apparatus includes a sensor array with a plurality of active pixels. Each active pixel in the sensor array includes: a three transistor (3T) sensor with a source follower transistor, and a detection diode coupled in series to a parasitic capacitor at a sensing junction. A gate of the source follower transistor amplifier is coupled to the sensing junction. The apparatus includes an insulator layer over the sensor array. The insulator layer provides a variable capacitance to the sensing junctions of underlying active pixels in response to portions of an object being proximate to the insulator layer. The variable capacitance is used to detect an image of the object.

    摘要: A sensor unit 11 generates a sensor signal according to proximity and contact of a manipulation object. A proximity detecting unit 12 performs proximity detection of the manipulation object, on the basis of the sensor signal. When a plurality of manipulation objects are detected by the proximity detection, a determining unit 13 sets a priority order to the detected manipulation objects and adopts a proximity detection result on the basis of the set priority order. For this reason, even though the plurality of manipulation objects are detected, the proximity detection result having the high priority order is adopted, so that erroneous detection can be prevented and an input manipulation can be correctly performed.

    摘要: A display device and a method for driving the same are provided by the present disclosure. The display device includes a display panel and a touch panel. The method includes: applying a horizontal synchronizing signal to a plurality of scanning lines of the display panel; and applying a touch driving signal to a plurality of touch driving signal lines of the touch panel; an orthographic projection of the scanning line receiving the horizontal synchronizing signal onto the display panel does not overlap an orthographic projection of the touch driving signal line receiving the touch driving signal onto the display panel at least within a predetermined time period. When the display device displays images within the predetermined time period, the scanning line receiving the horizontal synchronizing signal and the touch driving signal line receiving the touch driving signal are staggered, so capacitive coupling may hardly be generated between them, thereby a signal-noise ratio of the touch panel within the predetermined time period may be improved.

    摘要: The present disclosure provides a capacitive touch sensor for an electronic device. The touch sensor has a trace carrier having a sensing surface, a connecting surface, and a number of electrically conductive traces on the trace carrier. The traces form a sensing pattern on the sensing surface and pass from the sensing surface to the connecting surface. The sensor also includes a capacitive sensing circuit operable to electrically couple to the traces at the connecting surface of the trace carrier, and to sense a capacitance change. A touch position on the sensing surface is determined dependent upon the sensed capacitance change.
