  • Method and apparatus for sensing multi-touch inputs
    Patent number: 8830185
    Abstract: A method for sensing two or more touch inputs includes receiving sensing signals of the touch inputs from plural sensing electrodes, calculating a value dependent on a distance between the touch inputs based on the received sensing signals, and determining the existence of the two or more touch inputs if the calculated value is more than or equal to a threshold value. The plural sensor electrodes include a pair of sensing electrodes that correspond to same coordinates on a first axis, and the sensing signals are received from the pair of sending electrodes along the first axis.
    Type: Grant

    Date of Patent: September 9, 2014
    Assignee: Melfas, Inc.
