  • Patent number: 9041684
    Abstract: A touch controller processes a captured data frame and detects the presence of touch points in the data frame. The data frame includes a plurality of digital capacitance values organized as groups of sense line data and the touch controller determines for each digital capacitance value in a group of sense line data the difference between the digital capacitance value and an associated no-touch threshold to generate a baseline delta value for each digital capacitance value in the group. The touch controller selects the minimum baseline delta and adjusts each digital capacitance value in the group by the minimum baseline delta to generate adjusted sense line data. The touch control generates adjusted sense line data for each group of sense line data in the data frame and thereafter processes the groups of adjusted sense line data to detect the presence of touch points in the data frame.

  • Publication number: 20120300140
    Abstract: An ITO sensor design and method for making the same is optimized to minimize noise from an LCD. The design includes a two layer sensor design having a transmitter line (Tx) placed in a first layer and a receiver line (Rx) placed in a second layer in a diamond-shaped pattern. The diamond shape maximizes the sensitivity of the sensor.
