The present disclosure provides a mobile device and a method of distinguishing between different touch forces. The method includes steps of: preloading an area of a maximum touch region with a maximum force, presetting a relationship among a current force, an area of a current touch region, the maximum force and the area of the maximum touch region, and presetting at least two force levels, wherein each of the at least two force levels corresponds to a respective range of a ratio of the current force to the maximum force; detecting and calculating the area of the current touch region of the touch component when touched; according to the relationship, calculating the ratio of the current force to the maximum force by using the area of the current touch region, so as to determine a corresponding one of the at least two force levels.

Mobile device and method of distinguishing between different touch forces

A method for improving coordinate accuracy of a touch panel having sensing lines arranged to form an array includes the steps of: detecting existence of a touch point influencing at least one sensing line; determining existence of an edge sensing line; providing signal strengths to the at least one sensing line and a sensing line immediately adjacent to the at least one sensing line; generating a virtual sensing line extending out the touch panel and immediately adjacent to the at least one sensing line; providing a signal strength to the virtual sensing line; and obtaining actual coordinate of the touch point by weighing coordinates of the at least one sensing line, the sensing line immediately adjacent to the at least one sensing line and the virtual sensing line via system generated coordinates.
