Resistance Deviation Compensation Method and Coordinated Correction Method for Multi-Touch Panel

摘要

PURPOSE: A resistance deviation compensation method and a coordinate correction method of a multi touch panel are provided to apply the same voltage to a cell resistance film at every location of the multi touch panel, thereby accurately calculating a location coordinate for a contact point. CONSTITUTION: If a multi touch panel is designed, the surface resistance of each conductive pattern is calculated(S101,S103). Widths of the conductive patterns are corrected to correct the surface resistance(S105). A design error of the conductive pattern configuring the designed multi touch panel is corrected after adjusting the widths of the conductive patterns(S107). Therefore, all conductive patterns have the same resistance value.
