Title:
タッチパネルディスプレイ装置
Document Type and Number:
Japanese Patent JP4531358
Kind Code:
B2
Abstract:
A display apparatus comprises a display, a transparent conductive film (5) having a plurality of stimulation electrodes (17), a finger-worn insensitive electrode (11) electrically isolated from the stimulation electrodes and maintained at a constant potential, and a voltage applying device for establishing a potential difference between each stimulant electrode (17) and the insensitive electrode (11). When the transparent conductive film (5) is given a touch, the voltage applying device causes a state in which the potential of the stimulation electrodes is higher than that of the insensitive electrode, plural times intermittently or once in a predetermined period immediately after the touch, and varies the potential of the stimulation electrodes with time so as to intermittently cause a state in which the potential of the insensitive electrode is higher than that of the stimulation electrodes, in a predetermined pulse width and at a predetermined frequency during a continuing period of the touch thereafter.
