Abstract
Discloses are a mobile terminal having a proximity touch and a method for controlling a display screen thereof. A difference of recognition rates caused by a minute difference of capacitances generated when a human body approaches a touch screen depending on users can be calibrated to be suitable for each user. Also, in the state of the recognition rate being calibrated, operations of objects, i.e., icons, avatars and menus, displayed on a wallpaper and displaying effects on the wallpaper can variously be controlled according to a user's proximity touch, thereby allowing users to control the display screen more conveniently and accurately.
Claims9
A mobile terminal comprising:
- a display having a touch screen;
- a sensing unit configured to detect a proximity touch or a real touch of a pointer;
- and
- a controller configured to:
- control the display to display a reference figure and a guide figure upon the sensing unit detecting the proximity touch or the real touch;
- control the display to decrease or increase a size of the guide figure upon the sensing unit detecting movement of the pointer toward or away from the touch screen;
- and
- set a value of a capacitance of the touch screen as a maximum proximity capacitance or a minimum proximity capacitance when the size of the guide figure becomes equal to a size of the reference figure.
A method for calibrating a capacitance of a mobile terminal, the method comprising:
- displaying a calibration screen on a touch screen;
- detecting a proximity touch or a real touch of a pointer via the touch screen;
- displaying a reference figure and a guide figure on the calibration screen upon detecting the proximity touch or the real touch;
- decreasing or increasing a size of the guide figure upon detecting movement of the pointer toward or away from the calibration screen;
- comparing the size of the guide figure with a size of the reference figure;
- and
- setting a value of the capacitance of the touch screen as a maximum proximity capacitance or a minimum proximity capacitance when the size of the guide figure becomes equal to the size of the reference figure.
