Abstract
A mobile terminal including a wireless communication unit configured to wirelessly communicate using at least two different communication systems; a display unit including a backlight configured to apply light to a display screen of the display unit; a sensing unit configured to measure a temperature of the mobile terminal if the at least two different communication systems are simultaneously used; and a controller configured to adjust a brightness of the backlight based on the measured temperature and a preset temperature.
Claims18
A mobile terminal, comprising:
- a wireless communication unit configured to wirelessly communicate using at least two different communication systems;
- a display unit including a backlight configured to apply light to a display screen of the display unit;
- a sensing unit configured to measure a temperature of the mobile terminal if the at least two different communication systems are simultaneously used;
- and
- a controller configured to:
- adjust a brightness of the backlight when the measured temperature is equal to or higher than the preset temperature and the wireless communication unit switches from using a single communication system to using the at least two different communication systems,
- lower the brightness of the backlight by reducing the light of a first region of the display screen while maintaining the brightness of the backlight applying to a second region of the display screen, and
- adjust at least a size or arrangement of content displayed on the display unit corresponding to the second region of the display screen,
- wherein the sensing unit measures the temperature only when the at least two different communication systems are simultaneously used.
A method of controlling a mobile terminal, the method comprising:
- allowing wireless communication, via a wireless communication unit of the mobile terminal, wireless communication using at least two different communication systems;
- displaying, via a backlight applying light to a display screen of a display unit of the mobile terminal, information;
- measuring, via a sensing unit of the mobile terminal, a temperature of the mobile terminal if the at least two different communication systems are simultaneously used;
- and
- adjusting, via a controller of the mobile terminal, a brightness of the backlight when the measured temperature is equal to or higher than at the present temperature and the wireless communication unit switches from using a single communication system to using the at least two different communication systems,
- wherein the step of adjusting the brightness of the backlight comprises:
- reducing the light of a first region of the display screen while maintaining the brightness of the backlight applying to a second region of the display screen;
- and
- adjusting at least a size or arrangement of content displayed on the display unit corresponding to the second region of the display screen, and
- wherein the sensing unit measures the temperature only when the at least two different communication systems are simultaneously used.
