본 발명은 상기의 목적을 달성하기 위하여 배터리 전원 레벨을 검출하는 단계와, 상기에서 배터리 전원 레벨이 미리 설정된 일정값 이하인지 판단하는 단계와, 상기에서 배터리 전원 레벨이 일정값 이하로 판단되면 컬러 엘씨디의 구동을 모노 방식으로 전환시키는 단계를 수행함을 특징으로 한다.The present invention provides a method for detecting a battery power level, determining whether the battery power level is less than or equal to a predetermined value, and, if the battery power level is less than or equal to a predetermined value, to achieve the above object. It characterized in that the step of switching the driving of the mono way.
이하, 본 발명을 도면에 의거 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the drawings.
본 발명의 실시예에서는 본 발명의 요지를 불필요하게 흐릴 수 있는 공지 기능 및 구성에 대한 상세한 설명은 생략하기로 한다.In the embodiments of the present invention, a detailed description of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.
도1은 일반적인 본 발명의 실시예를 위한 장치의 블럭도로서 이에 도시한 바와 같이, 씨피유(CPU)(110), 컬러 엘씨디(120), 배터리(130), 키패드(140) 및 메모리(150)를 구비하여 구성한다.1 is a block diagram of a device for a general embodiment of the present invention, as shown therein, including CPI (110), color LCD (120), battery (130), keypad (140), and memory (150). It is provided with a.
상기 씨피유(110)는 대기(stand-by) 상태에서 배터리(130)의 충전 레벨을 A/D 단자로 검출하고 그 검출된 배터리 충전 레벨이 미리 설정된 일정값 이상이면 상기 컬러 엘씨디(120)를 컬러 방식으로 구동시키고 반대로, 일정값 이하로 판단되면 상기 컬러 엘씨디(120)를 모노 방식으로 구성시키도록 MSM5105 칩을 사용하여 구성한다.The CPI 110 detects the charge level of the battery 130 with the A / D terminal in a stand-by state, and if the detected battery charge level is greater than or equal to a predetermined value, the color LCD 120 is colored. On the contrary, if it is determined that the predetermined value or less, the color LCD 120 is configured using the MSM5105 chip to configure the mono way.
상기 컬러 엘씨디(120)는 컬러 방식과 모노 방식의 디스플레이가 가능하도록 구성한다.The color LCD 120 is configured to enable a color display and a mono display.
이와같이 구성한 본 발명의 실시예에 대한 동작 및 작용 효과를 도2의 동작 순서도를 참조하여 설명하면 다음과 같다.The operation and the effect of the embodiment of the present invention configured as described above will be described with reference to the operation flowchart of FIG. 2.
전원이 온되면 씨피유(110)는 초기화 과정을 실행한 후 휴대용 단말기를 대기 상태(Stand-by) 상태로 진입시킨다.When the power is turned on, the CPI 110 enters the portable terminal into a standby state after executing the initialization process.
이후, 스탠바이 상태에서 씨피유(110)는 A/D 단자를 점검하여 배터리(130)의 전원 전압을 검출하고 그 검출된 전압이 미리 설정된 일정값(예로, 배터리 바가 1개 이하)가 되었는지 판단한다.Thereafter, in the standby state, the CPI 110 checks the A / D terminal to detect a power supply voltage of the battery 130 and determines whether the detected voltage reaches a predetermined value (for example, one battery bar or less).
이에 따라, 배터리(130)의 충전 전압이 미리 설정도니 값 이상(예로, 배터리바가 2개 이상)으로 판단되면 씨피유(110)는 컬러 엘씨디(120)의 구동 방식을 현재의 컬러 방식으로 유지시키게 된다.Accordingly, when the charging voltage of the battery 130 is determined to be greater than or equal to a preset value (eg, two or more battery bars), the CPI 110 maintains the driving method of the color LCD 120 in the current color method. .
이후, 배터리(130)의 충전 전압이 미리 설정된 값 이하라고 판단되면 씨피유(110)는 컬러 엘씨디(120)의 구동 방식을 모노 방식으로 설정하게 된다.Subsequently, when it is determined that the charging voltage of the battery 130 is equal to or less than a preset value, the CPI 110 sets the driving method of the color LCD 120 to a mono method.
상기와 같은 과정은 휴대용 단말기가 대기 상태가 될 때마다 반복적으로 수행하게 된다.The above process is repeatedly performed whenever the portable terminal becomes a standby state.
그리고, 대기 상태에서 호 연결이 시도되면 씨피유(110)는 키패드(140)를 점검하여 해당 상대방 전화번호로 호 연결 작업을 실행하게 된다.When the call connection is attempted in the standby state, the CPI 110 checks the keypad 140 and executes a call connection work with the corresponding phone number.
상기에서 상세히 설명한 바와 같이 본 발명은 컬러 모드의 엘씨디를 구동할 때 배터리의 충전 전압이 미리 설정한 일정값 이하가 되면 엘씨디의 구동 방식을 모노 방식으로 전환시킴으로써 배터리의 소모 전류를 줄여 휴대용 단말기의 대기 시간을 연장시킬 수 있는 효과가 있다.As described in detail above, the present invention reduces the current consumption of the battery by switching the driving method of the LCD to the mono mode when the charging voltage of the battery is lower than a predetermined value when driving the LCD in the color mode, thereby waiting for the portable terminal. It is effective to prolong the time.
또한, 본 발명은 배터리의 충전 전압이 일정값 이하가 되면 엘씨디를 모노 방식으로 구동함으로써 충전 시기를 간편하게 알 수 있어 사용자에게 편리함을 제공하는 효과가 있다.In addition, the present invention has the effect of providing convenience to the user can easily know the charging time by driving the LCD in a mono manner when the charging voltage of the battery is below a certain value.
