Patent ID: 8384678

Claim:
A touch sensing device comprising: a touch sensor array including a plurality of touch sensors; a plurality of integrated circuits (ICs) that convert an output of the touch sensor array into digital data and generates raw data; and a data correction unit that generates correction values using differential values between adjacent raw data in the raw data generated by the ICs and removes successive correction values equal to or greater than a predetermined critical value from the correction values when a number of successive correction values equal to or greater than the predetermined critical value is less than a predetermined reference value, wherein the data correction unit generates a mirror data in each of the ICs and performs a differential operation between the mirror data and a first raw data from each of the ICs to generate a first correction value for the first raw data, wherein the mirror data for each of the ICs is a pseudo data selected from among the raw data output from each of the ICs, and wherein when all of the differential values between the adjacent raw data are equal to or less than a predetermined critical value, the data correction unit selects second raw data adjacent to the first raw data as the mirror data.
