Abstract:
Provided is a touch panel (200). The touch panel (200) includes a first substrate (260), a second substrate (210), a first electrode (241), a second electrode (242), a third electrode (220), and a dielectric layer (230). The second substrate (210) faces the first substrate (260). The first electrode (241) is on one surface of the first substrate (260). The second electrode (242) is spaced apart from the first electrode (241) on a same plane as the first electrode (241). The third electrode (220) is on one surface of the second substrate (210) and overlaps the first electrode (241) and the second electrode (242). The dielectric layer (230) is between the first electrode (241) and the third electrode (220) and between the second electrode (242) and the third electrode (220) and includes an anisotropic dielectric material.
Abstract:
Provided is a display device. The display device includes: a touch sensitive element including an electroactive layer and a plurality of electrodes disposed on at least one of the top surface and the bottom surface of the electroactive layer; a shielding layer on the touch sensitive element; a display panel on the shielding layer; and a touch sensor integrated in the display panel and including a plurality of first touch electrodes and a plurality of second touch electrodes spaced apart from the plurality of first touch electrodes, and the shielding layer is electrically connected with the plurality of first touch electrodes or the plurality of second touch electrodes.
Abstract:
There are provided a touch sensitive device, a method of driving the touch sensitive device, and a display device including the touch sensitive device. The touch sensitive device includes: an electroactive layer made of an electroactive polymer; and one or more first electrodes and one or more second electrodes disposed on only one surface of the electroactive layer, in which the first and the second electrodes are made of a conductive material. Since the first and the second electrodes of the touch sensitive device are disposed only on one surface of the electroactive layer, a driving voltage of the touch sensitive device is reduced and transmissivity is improved, as compared with a case where first and second electrodes are disposed on different surfaces of an electroactive layer.
