Abstract
The present invention provides a touch sensitive processing method for detecting a liquid line when a touch panel half submerged in conductive liquid, wherein the touch panel comprises multiple parallel first electrodes and multiple parallel second electrodes, the touch sensitive processing method comprising: determining whether a liquid line piece group touches two sides of the touch panel if the liquid line piece group does exists; calculating two averaged values of sensing information with regard to two parts of the touch panel separated by the liquid line piece group if it touches two sides of the touch panel; determining a part of the touch panel having a larger averaged value is above the conductive liquid and another part of the touch panel is below the conductive liquid; and determining a liquid line according to a surface between the part above the conductive liquid and the liquid line piece group.
