  • Radio communication terminal and control method therefor
    Patent number: 6829494
    Abstract: In a radio communication terminal, a microprocessor determines a mode selected by user manipulation of a key input portion. The microprocessor turns on a backlight of a display with the backlight in accordance with the determined mode, controls the time period of a bright display mode, and turns the backlight off after the lapse of the period to switch the bright display mode to a dark display mode. The ON time period in the bright display mode is set longer in another mode than in a normal mode. The backlight ON time is optimally controlled in correspondence with a mode selected by the user, thereby improving the operability and prolonging the service life of the battery.

  • Electronic device and mobile radio terminal apparatus
    Publication number: 20030064762
    Abstract: A picture processing unit converts moving picture data which is read from a memory unit by a control unit into picture data and voice data. The picture data is displayed on a display unit through a driver and the voice data is output from a speaker through a PCM code processing unit and an amplifier. If a folding detecting unit detects that a terminal apparatus is in a folded state during reproduction and output of a moving picture through the display unit, the control unit continues picture processing of the picture processing unit. However, the control unit suspends converting the voice data into an analog voice signal by the PCM code processing unit or an amplifying operation of an amplifier to stop output of the voice.
