MULTI-FUNCTION TOUCH PANEL, MOBILE TERMINAL INCLUDING THE SAME, AND METHOD OF OPERATING THE MOBILE TERMINAL
First Claim
1. A multi-function touch panel comprising:
- a touch panel lower plate disposed opposite to a touch panel upper plate at a predefined gap; and
a touch panel driving circuit for detecting a signal according to proximity detection and touch detection by alternately operating with a resistive method and a capacitive method according to a predefined cycle based on the touch panel lower plate and the touch panel upper plate.

Abstract
A multi-function touch panel, a mobile terminal including the same, and a method of operating the mobile terminal are provided. The method includes performing, upon setting a mixed mode that alternately operates a touch panel in which a touch panel lower plate and a touch panel upper plate are disposed at a predefined gap with a resistive method and a capacitive method at a predefined cycle, proximity detection of an object approaching the touch panel and touch detection according to a predefined pressure applied to the touch panel according to a capacitive method at a predefined cycle, generating a distinguished input signal according to the proximity detection or the touch detection, and operating a specific user function according to the generated input signal.
