Abstract:
1. A sensing structure for use in a displayer, the displayer comprising a substrate and a panel, the panel being disposed opposite to the substrate, the sensing structure comprising: a conductive assembly; a plurality of sensing elements, being disposed between the substrate and the panel, every several adjacent ones of the sensing elements forming a sensing area opposite to the panel, so as to form a plurality of sensing areas on the panel; and a process module, being electrically connected to the sensing elements via the conductive assembly, and storing a position data of each of the sensing elements opposite to the panel; wherein each of the sensing elements generates a touch voltage in response to at least one touch on the sensing areas, the process module is configured to receive the touch voltages and calculate at least one touch position of the at least one touch opposite to the panel according to the position data and the touch voltages, the process module comprises: a transformation unit, being configured to receive the touch voltages and transform each of the touch voltages into a digital signal; and a control unit, being electrically connected to the transformation unit, the control unit being configured to store the position data, receive the digital signals, select at least one selected area from the sensing areas in response to the digital signals and calculates the at least one touch position of the at least one selected area, the at least one selected area is the one of the sensing areas having a peak voltage value, the peak voltage value is determining by: calculating an area voltage value of each of the sensing areas, wherein the area voltage value is an average value of each touch voltage of each sensing element in each sensing area; and selecting the adjacent sensing area with the greatest area voltage value from the sensing areas.
