Abstract

PURPOSE:To reduce the power consumption and to prolong the service life of a battery by providing a light emitting diode and a liquid crystal display device and using only the liquid crystal display device as an indicator when the telephone set is carried. CONSTITUTION:The indicator of a light emitting diode 22 is not lighted when the telephone set is carried and only a liquid crystal display device is used. Moreover, the display device 21 is always lighted when the telephone set is mounted and the diode 22 acts like an indicator representing the display content and the status by its lighting. Since the diode 22 is lighted when the telephone set is mounted, the visual angle is wide and observed easily. Moreover, the lighting or extinguishment of the indicator is confirmed from a remote location. Furthermore, when the telephone set is carried, since the display device 21 is used as the indicator, the power consumption is saved and the operating time of the battery is prolonged.

ても見やすい。(Function) The present invention has the following effects due to the above configuration. In other words, since the light emitting diode indicator is activated when mounted on a moving object, it solves the problem of liquid crystal displays, which have narrow viewing angles and are difficult to see from diagonal directions.Also, since the indicator can be checked by turning it on or off, it is easy to see even from a distance. .

また携帯時には液晶表示器をインジケータとして使用す
