  • Multi-touch screen device
    Patent number: 9671882
    Abstract: Provided is a multi-touch screen device that may calculate x and y orthogonal coordinates of a touch area even if a receiving/transmitting element is arranged on only one of the x-axis and the y-axis. The receiving/transmitting element is not arranged on both the x-axis and the y-axis so that an infrared ray scans a touch area in a matrix configuration, but an infrared receiving/transmitting element is arranged on only one of the x-axis and y-axis so that one receiving module sequentially scans the touch area using a right-angle scan measurement signal and an oblique-angle scan measurement signal. The multi-touch screen device may decrease the number of receiving/transmitting elements for use and solve a ghost image problem that occurs in a multi-touch operation that uses infrared rays.

  • Multitouch recognizing device
    Patent number: 9292132
    Abstract: A multi-touch recognizing device for distinguishing an illusion from an actually touched position and an illusion position by using an inclination angle measuring method, minimizing time for measuring a touch position, and more accurately measuring the position is provided.
