Abstract
A method for sensing contactless touch using a touch sensor structure that senses contacting touch by operating some of touch electrode lines operating as touch driving electrodes and some of touch electrode lines operating as touch sensing electrodes upon contacting touch driving, as touch driving electrodes for sensing contactless touch, in a contactless touch driving period distinct from a contacting touch driving period.
