Abstract
Official abstract text for this publication.
Disclosed herein are a touch screen and a method for driving the same. The touch screen includes: a switching unit including a plurality of switches connected to traces of driving lines and sensing lines of the touch screen, respectively; a sensing unit sensing capacitance and electromagnetic resonance (EMR) according to a switching operation of the switching unit; and a main controlling unit controlling the switching operation of the switching unit according to an operation mode of the touch screen. Therefore, it is possible to improve sensitivity of sensing without increasing a bezel region of the touch screen. In addition, the EMR and the capacitance may be sensed using the same trace structure, and an antenna pattern may be formed and operated as an antenna.
First claim
Opening claim text (preview).
What is claimed is: 1. A touch screen comprising: a switching unit including a first switching unit and a second switching unit comprised of a plurality of switches connected to traces formed on one side of driving lines and sensing lines of the touch screen, respectively; a sensing unit sensing capacitance or electromagnetic resonance (EMR) according to a switching operation of the switching unit; and a main controlling unit controlling the switching operation of the switchin…
