a mode selecting unit selecting an operation mode of the touch panel from a touch recognition mode and a remote gesture recognition mode;
a first switching circuit unit electrically connected to the first electrode pattern by a switching operation according to the selection of the operation mode of the touch panel;
a second switching circuit unit electrically connected to the second electrode pattern by a switching operation according to the selection of the operation mode of the touch panel; and
a controlling unit controlling the switching operations of the first switching circuit unit and the second switching circuit unit and a driving signal applied to the first electrode pattern and the second electrode pattern, and detecting changes in capacitance sensed from the first electrode pattern and the second electrode pattern according to the selection of the operation mode of the touch panel.

Abstract
Disclosed herein is a touch screen to recognize a remote gesture including a touch panel, a mode selecting unit, first and second switching circuit units and a controlling unit. Slimness and lightness of a mobile device having the touch screen may be realized by integrating touch and remote gesture recognition functions with the electrode patterns by switching operations of the first and second switching circuit units. In addition, a signal to noise ratio (SNR) available for both the touch and remote gesture recognitions may be secured by forming a width of a first electrode pattern of the touch screen in a metal mesh pattern having a wider width than a mutual induced capacitive type according to the prior art.

8. A controlling method of a touch screen to recognize a remote gesture, the method comprising:
-
performing a touch recognition mode detecting a change in mutual induced capacitance sensed from a first electrode pattern according to a driving signal sequentially applied to a second electrode pattern of a touch panel to thereby determine a touch location; selecting a mode selecting whether or not switching from the touch recognition mode to a remote gesture recognition mode; when the remote gesture recognition mode is selected, performing the remote gesture recognition mode forming first and second electrode pattern groups and then sensing a time difference between changes in self-capacitance in the first and second electrode pattern groups according to a gesture of a user; and determining whether or not terminating the remote gesture recognition mode selecting whether or not switching from the remote gesture recognition mode to the touch recognition mode according to whether or not a specific gesture is input. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)
