Abstract: A method for improving linearity of touch system coordinates first reads two-dimensional raw data of a capacitive touch panel. Next, it reads a pixel and adjacent pixels of the pixel from the two-dimension raw data. Then, it determines whether the value of the pixel is great than a pre-determined threshold. If the value of the pixel is not greater than the pre-determined threshold, it then determines whether there is a value of the adjacent pixels is greater than the pre-determined threshold. If there is no value of the adjacent pixels greater than the pre-determined threshold, it sets the value of the pixel to a pre-determined value. Otherwise, it reserves the value of the pixel in order to increase the linearity of two-dimensional raw data so as to avoid the interference of noise to the two-dimensional raw data.

Abstract: A driving frequency selection method is used in a capacitive multi-touch system. When the system operates in an idle mode, an active driving frequency is selected randomly from N candidates, and a self-capacitance driving and sensing is used to detect touch points. When there are touch points, the capacitive multi-touch system is switched to an active mode to acquire an image raw data for finding the positions of touch points. In the active mode, noise is calculated from the image raw data. When the noise exceeds a predetermined value, the system is switched back to the idle mode, and the self-capacitance driving and sensing is applied to N?1 active driving frequencies other than the previously selected active driving frequency to acquire N?1 self-capacitance image raw data. The method determines one with a minimum noise and selects the corresponding frequency as a currently active driving frequency.

Abstract: A low power switching mode driving and sensing method for capacitive multi-touch systems is used in a capacitive multi-touch system with a capacitive touch panel. When the capacitive touch system operates in an idle mode, the method uses a self-capacitance driving and sensing technology to detect touch points. When the touch points are detected on the capacitive touch panel, the capacitive touch system is switched to an active mode and uses a mutual-capacitance driving and sensing technology to detect touch points for accurately acquiring the positions related to the touch points detected. During a predetermined time interval in which there is no touch point detected, the method automatically performs a calibration to update a mutual-capacitance base image raw data and a self-capacitance base image raw data, so as to overcome the drifting of sensors of the capacitive touch system.
