Abstract: A sensitivity compensation method of a touch input device sensing a touch pressure may be provided. The sensitivity compensation method includes: detecting a capacitance change amount by applying a pressure to a plurality of points defined on a touch sensor panel; generating a raw data for the capacitance change amount of the defined point; generating a decimal value data for each of the sets by dividing a data value within the set by a maximum value within the set; calculating an average value of each defined point; generating a representative value data by calculating a value corresponding to all the points of the touch sensor panel; calculating a balance factor on the basis of the representative value data; and compensating for a touch pressure sensitivity of the touch input device by using the balance factor.
