An apparatus and a method for controlling a touch panel are disclosed herein, the apparatus includes an object detection module and an adjusting device. The object detection module can detect a position of at least one object contacting the touch panel. A position analyzer recognizes position of the object and the adjusting device can set the touch panel to a predetermined position according to the result recognized by the position analyzer.

Multi-touch detection method for touch panel

A method and a driving apparatus for identifying a sensing value of a touch panel are provided. The method includes sensing a plurality of electrodes of the touch panel to obtain raw data and baseline data of each electrode, wherein an electrode Sdenotes an ielectrode of the electrodes in the touch panel. A sensing value of the electrode Sis calculated in accordance with the raw data and the baseline data of the electrode S. When sensing values of all electrodes Sare smaller than a threshold value, the baseline data of the electrode Sis updated in accordance with the raw data of the electrode S. When a sensing value of any one electrode Sof the electrodes is larger than the threshold value, the baseline data of the electrodes is suspended from being updated.

Method and driving apparatus for identifying sensing value of touch panel

A touch panel and a differential detection method thereof are disclosed. A controller provides a driving signal to the i-th scan electrode. During providing the driving signal to the i-th scan electrode, the controller senses the feature difference value between two neighboring sensing electrodes within the plural sensing electrodes, and senses the feature difference value &#x394;Ci between the k-th sensing electrode within the sensing electrodes and a reference feature value, in which the feature difference values between the j-th sensing electrode and the (j+1)-th sensing electrode is represented by &#x394;C(i,j). The controller set the feature value of a base sensing point within a plurality of sensing points of the touch panel as a base feature value, and use the base feature value, the feature difference values &#x394;Ci and the feature difference values &#x394;C(i,j) to calculate the feature values of the sensing points.

Touch panel and differential detection method for same

A positioning method and a driving apparatus of a touch panel are provided. The touch panel includes a conductive layer with anisotropic conductivity, a plurality of first electrodes and a plurality of second electrodes. The first electrodes and the second electrodes are respectively disposed on a first side and a second side of the conductive layer. The first electrodes and the second electrodes are sensed to obtain a plurality of sensing values. A first relative extreme portion at least having a relative extreme is defined among the first electrodes. A second relative extreme portion at least having a relative extreme is defined among the second electrodes. A ratio of sensing values is calculated according to the first relative extreme portion and the second relative extreme portion. A position of a touch point on the touch panel in a first axial direction is calculated with the ratio of sensing values.

Positioning method and driving apparatus of touch panel

A multi-touch detecting method is adapted for detecting locations of touched points on a touch panel including first and second conductive films, and includes following steps. First measuring points of the first conductive film distributed along X-axis of a Cartesian plane are scanned, and x-components are determined accordingly. Second measuring points of the second conductive film distributed along Y-axis of the Cartesian plane are scanned, and y-components are determined accordingly. A first voltage is applied to the first conductive film, and A second voltage is applied to at least one of the second measuring points with the location on the Y-axis adjacent to or overlapping one of the y-components. Voltages at the first measuring points with the locations on the X-axis adjacent to or overlapping the x-components are measured sequentially and one of the y-components and one of the x-components are outputted.
