Abstract
A single layer self-capacitance touch screen and its data processing method which can realize multi-touch identification, the said touch screen includes at least two self-capacitance electrode assemblies independent of each other, all of which are located in the same plane layer and fully cover the whole touch zone of the touch screen without overlapping each other; the said self-capacitance electrode assembly includes at least a pair of self-capacitance coupling electrode couples, which include two electrode plates seated in the same plane, and these two electrode plates all include their own straight-line electrode plate coupling side and straight-line electrode plate base, which have included angle of acute angle; in the self-capacitance electrode assembly, the center lines of the self-capacitance coupling electrode couples are placed parallel to each other, and the center lines of arbitrarily two self-capacitance coupling electrode couples are also placed parallel to each other. This invention fully utilizes simple technological structure feature of single layer self-capacitance touch screen and realizes multi-point touch control function at possible lowest manufacturing cost.
