Abstract

PURPOSE: A method for minimizing the power consumption of a portable phone is provided to minimize the power consumption of a portable phone by turning off the power of the LCD when the line is busy. CONSTITUTION: If a telephone call is received, a user holds the portable terminal's receiver to his ear(S41). At this moment, a sensor installed in the receiver senses it(S42). The power of the LCD of the portable phone is turned off by the sensing of the sensor(S43). In this manner, when the user puts the portable phone to his ear, a main control unit judges that the line is busy, and turns off the power of the LCD. In addition, when the user puts the portable phone into his pocket or bag, the sensor also detects it so that the power of the LCD can be turned off.

And controlling the liquid crystal display of the mobile phone.

도 2는 본 발명의 휴대폰의 구성을 보여주는 외관 사시도이다.Figure 2 is an external perspective view showing the configuration of a mobile phone of the present invention.

도 2에 도시된 바와 같이 본 발명의 휴대폰은 휴대폰 본체(20), 키 패드(21), 수화부(22), 디스플레이부(23) 및 수화부(22)에 근접하여 형성된 센서(24)로 구성되어 있다.As shown in FIG. 2, the mobile phone of the present invention is composed of a mobile phone main body 20, a keypad 21, a receiver 22, a display 23, and a sensor 24 formed in proximity to the receiver 22. have.

상기와 같은 구성을 갖는 본 발명의 휴대폰의 동작에 대해 본 발명의 특징인 센서(24)를 중심으로 설명하기로 한다.The operation of the mobile phone of the present invention having the above configuration will be described with reference to the sensor 24 which is a feature of the present invention.

본 발명의 휴대폰에 채용된 센서(24)로는 적외선 센서, 압력 센서, 온도 센서등이 사용될 수 있는데, 각각의 경우에 다음과 같은 특징이 있다.As the sensor 24 employed in the mobile phone of the present invention, an infrared sensor, a pressure sensor, a temperature sensor, or the like may be used. In each case, the following characteristics are provided.

첫째, 적외선 센서를 사용했을 경우, 반사파의 강도를 이용하여 물체의 원근을 파악하여 LCD(23)의 전원을 켜고 끈다.First, when an infrared sensor is used, the power of the LCD 23 is turned on and off by grasping the perspective of the object using the intensity of the reflected wave.

둘째, 압력 센서를 사용했을 경우에는, 일반적으로 휴대폰을 가지고 통화할 때, 휴대폰을 귀에 밀착시키고 통화하므로, 이때, 수화부에 설치된 압력 센서의 압력 감지에 의해 LCD(23)의 전원을 켜고 끈다.Second, in the case of using a pressure sensor, when talking with the mobile phone in general, the mobile phone is in close contact with the ear, and at this time, by turning on and off the LCD 23 by the pressure sensing of the pressure sensor installed in the receiver.

셋째, 온도 센서를 사용했을 경우에는, 일반적으로 휴대폰을 몸 가까이 위치시키게 되는데, 이때, 수화부에 설치된 온도 센서의 온도 감지에 의해 LCD(23)의전원을 켜고 끈다.Third, when the temperature sensor is used, the mobile phone is generally located close to the body. At this time, the power of the LCD 23 is turned on and off by sensing the temperature of the temperature sensor installed in the receiver.

이하, 상기 센서(24)로부터 감지된 신호를 가지고 상기 LCD(23)의 전원을 온/오프 시키는 메카니즘에 대해 도 3을 참조하여 상세히 설명하기로 한다.Hereinafter, a mechanism for turning on / off the power of the LCD 23 with the signal sensed by the sensor 24 will be described in detail with reference to FIG. 3.

도 3을 참조하면, 먼저 A의 경우, 주 제어부(미도시)는 센서(24)로부터 입력되는 감지신호(값)를 판독하고, 그 감지값이 미리 설정된 온/오프 작동 임계값보다 큰지의 여부를 판별한다.Referring to FIG. 3, first, in the case of A, the main controller (not shown) reads a detection signal (value) input from the sensor 24, and whether the detection value is larger than a preset on / off operation threshold. Determine.

하나의 실시예로서, 상기와 같은 판별 과정에서 감지값이 임계값보다 크면, LCD(23)의 전원을 온 시키게 된다. 그리고, 감지값이 임계값 이하일 때는 LCD(23)의 전원을 오프시킨다.In one embodiment, if the detection value is greater than the threshold value in the determination process as described above, the power of the LCD 23 is turned on. When the detected value is less than or equal to the threshold value, the LCD 23 is turned off.

또한, B의 경우, 주 제어부는 센서(24)로부터의 감지신호(값)를 판독하고, 그 감지값이 미리 설정된 온/오프 작동 임계값보다 작은지의 여부를 판별한다.In addition, in the case of B, the main control unit reads the detection signal (value) from the sensor 24 and determines whether the detection value is smaller than a preset on / off operation threshold.

하나의 실시예로서, 상기와 같은 판별 과정에서 감지값이 임계값보다 작으면, LCD(23)의 전원을 오프시키게 되고, 감지값이 임계값 이상일 때는 LCD(23)의 전원을 온 시킨다.In one embodiment, if the detected value is less than the threshold in the above-described determination process, the power of the LCD 23 is turned off, and if the detected value is more than the threshold, the power of the LCD 23 is turned on.

그러나 A, B의 경우 모두, 상기와 같은 조건은 사용자나 휴대폰 제작자에 의해 얼마든지 변경이 가능할 것이다.However, in the case of both A and B, the above conditions may be changed by the user or the mobile phone maker.

도 4는 본 발명에 따른 휴대폰의 전력 소모 감축 방법의 실행 과정을 나타낸 순서도이다.4 is a flowchart illustrating an execution process of a method of reducing power consumption of a mobile phone according to the present invention.

도 4를 참조하면, 먼저 전화가 걸려 오면, 사용자는 걸려 온 전화를 받기 위해 휴대폰의 수화부(22)를 귀에 댄다(S41).Referring to FIG. 4, first, when a call is received, the user puts the earpiece 22 of the mobile phone in order to receive an incoming call (S41).

이때, 휴대폰의 수화부(22)에 설치된 센서(24)가 이를 감지하며(S42), 상기 센서(24)의 감지에 의해 휴대폰의 LCD(23)의 전원이 꺼지게 된다(S43).At this time, the sensor 24 installed in the receiver 22 of the mobile phone detects this (S42), and the power of the LCD 23 of the mobile phone is turned off by the detection of the sensor 24 (S43).

이와 같이, 휴대폰의 수화부(22) 부분에 센서(적외선 센서, 압력 센서, 온도 감지센서)를 부착하여 사용자가 휴대폰을 귀에 대면, 통화 중으로 인식을 하여 LCD(23)의 전원을 끄고, 휴대폰을 귀에서 떼었을 때는 다시 LCD(23)의 전원을 켜 주게 되며, 이에 따라 , 불필요한 전력의 소모를 줄일 수 있게 된다.In this way, by attaching a sensor (infrared sensor, pressure sensor, temperature sensor) to the receiver 22 of the mobile phone, when the user touches the mobile phone to the ear, the user recognizes as a call, turns off the power of the LCD 23, and the mobile phone to the ear When removed, the LCD 23 is turned on again, thereby reducing unnecessary power consumption.

또한, 사용자가 휴대폰을 가방이나 주머니 속에 넣었을 때도 센서가 감지하여 LCD(23)의 전원을 꺼 줌으로써 전력의 소모를 줄일 수 있게 된다.In addition, even when the user puts the mobile phone in a bag or pocket, the sensor detects the power of the LCD 23 by turning off the power can be reduced.

상기와 같이 설명한 본 발명의 휴대폰의 전력 소모 감축 방법에 의하면, 사용자의 신체 일부위가 수화부에 근접되었을 때, 그것을 감지하여 LCD의 전원을 끄게 되므로, 휴대폰이 통화중일 때 전력 소모를 줄일 수 있다. 특히, 휴대폰의 전원이 조금밖에 남지 않았을 때 탁월한 절전 효과가 있다.According to the method of reducing power consumption of the mobile phone of the present invention described above, when the user's body part is close to the receiver, it detects it and turns off the LCD, thereby reducing the power consumption when the mobile phone is in a call. In particular, there is an excellent power saving effect when the phone has only a little power left.
