Claim Text:
1. A touch system comprising: a plurality of chips connected to sensing lines of a plurality of areas of a touchscreen panel divided into the plurality of areas and a boundary area among the plurality of areas, wherein the chips corresponding to adjacent areas share the sensing line of the boundary area among the adjacent areas, and the plurality of chips differentially amplify sensing signals of the adjacent sensing lines included in the areas, which correspond to the plurality of chips, and the boundary area adjacent to the areas, wherein each of the chips performs first sensing that differentially amplifies sensing signals of sensing lines in even sequences and sensing signals of sensing lines adjacent to one side of the sensing lines in even sequences for one direction of the touchscreen panel, and second sensing that differentially amplifies the sensing signals of the sensing lines in even sequences and sensing signals of sensing lines adjacent to the other side of the sensing lines in even sequences.
