HAPTIC SENSE-GENERABLE TOUCH SCREEN WITH MINIMIZED STRUCTURE ADDED TO GENERATE HAPTIC SENSE

摘要

PURPOSE: A haptic sense-generable touch screen can provide button feelings or various touch feelings by vibrating a substrate of a touch panel based on electrostatic force generated in portions where a hand is touched.;CONSTITUTION: A touch panel comprises a substrate with electrodes (203,207). An additional electrode (211) generates haptic sense on the touched portions of the touch panel using electrostatic force generated between the electrodes. The additional electrode is formed above an upper substrate of a display panel. The touch panel is formed above the additional electrode and is an analog resistive type or a capacitive overlay type.;COPYRIGHT KIPO 2013
