METHOD OF DRIVING TOUCH PANEL

摘要

Disclosed herein is a method of driving a touch panel having driving lines, sensing lines, and node capacitors between neighboring driving lines and sensing lines. The method includes pairing two neighboring driving lines, setting the pairs such that each of the pairs is driven using driving signals having an opposite phase, shuffling positions of the pairs so that at least one set of neighboring pairs includes different driving lines, classifying or combining at least two shuffled pairs into one group, generating Hadamard codes based on the pairs in each group, and simultaneously driving the driving lines in each of the generated Hadamard codes.

1. A method of driving a touch panel having driving lines, sensing lines, and node capacitors between neighboring driving lines and sensing lines, the method comprising:
pairing neighboring driving lines to form a plurality of pairs such that each of the plurality of pairs is driven using driving signals having an opposite phase; shuffling positions of the plurality of pairs so that at least two neighboring pairs include different driving lines; classifying or combining at least two shuffled pairs into a first group; generating Hadamard codes based on the pairs in each group, including the first group; and simultaneously driving the driving lines in each of the generated Hadamard codes.
