Abstract
A control circuit of an in-cell touch panel device associates a touch position P1 and a touch position P2 with each other when a refresh rate is F1 and a touch-to-touch distance d1 between the successive touch positions P1 and P2 is equal to or less than a determination distance D1. The control circuit associates a touch position P3 and a touch position P4 with each other when a touch-to-touch distance d2 between the touch position P3 detected last in a period in which the refresh rate is F2 lower than F1 and the touch position P4 detected first since a period in which the refresh rate is F1 starts is equal to or less than a determination distance D2 greater than the determination distance D1.
