摘要： A method of matrix sensing using delay-based capacitance sensing, including using X-axis lines as active lines for capacitance measurements and using Y-axis lines as a disturbance to identify the location of a touch in a key matrix is disclosed. A sensing signal is applied to the X-axis lines, and a disturbance signal is applied to the Y-axis lines. If a location is touched, cross-capacitance is reduced, which is measured by sweeping data along the X-axis lines.

摘要： A touch screen uses a combination of capacitive sensing and inductive sensing applied to the same sensor pattern. A capacitive sensor uses the electric field formed by the columns and rows of the sensor matrix. An inductive sensor uses the magnetic field formed by current flowing in column and row lines to induce an inductive pen. Using the same sensor lines, the magnetic field created by the oscillating inductive pen is detected. Both methods require no moving elements in the sensor and it is possible to combine both method of detections in the same sensor pattern. Using switch matrices, the sensor lines are operated in an open loop fashion for the capacitive detection mode, and are operated in a closed loop fashion for the inductive detection mode.

摘要： A touch sensitive display includes a capacitive touch sensor configured to output capacitance values. A motion sensor makes a motion detection and generates a motion signal including a motion value indicative of sensed motion detection. A touch detection circuit is coupled to receive the capacitance values and motion values. The touch detection circuit processes the capacitance values to make a hovering detection and a touching detection with respect to the display. The touch detection circuit further generates an output signal including the motion value correlated in time with each of the hovering detection and touching detection. The output signal may be processed as a user interface control signal. The output signal may also be processed to determine an impulsive strength of the touching detection as a function of an elapsed time between hover and touch and the measured motion values.
