KR200291367Y1 - Apparatus of power consumption control in the mobile terminal - Google Patents

Abstract

The present invention relates to a device for reducing power consumption during a call in a mobile terminal.

Conventionally, the display of the panel is continuously operated during a call in the mobile terminal, but the present invention is designed to prevent unnecessary power consumption by turning off the panel display by determining when the speaker of the mobile terminal is talking to the ear. To this end, the present invention consists of a distance determining unit for determining whether the speaker portion of the telephone is in contact with or near the ear during a call, a call detection unit for determining that the call is in progress, and a control unit for controlling the power of the display and the signal line. It turns off the panel display to reduce power consumption and turns it back on when it is far away from the ear so that the user can see the display when needed during a call. The present invention reduces the unnecessary power consumption of the display, thereby increasing the use time of the mobile terminal.

Description

Apparatus of power consumption control in the mobile terminal}

The present invention relates to power control of a device for reducing power consumption of a mobile terminal, and has conventionally used a method of maintaining the display in a normal display state during a call or lowering only brightness after a predetermined time. If you use handsfree or earphones without opening the folder, the display is turned off.

In the present invention, since the user does not need to look at the display when the user is talking with the built-in speaker of the mobile terminal, the unnecessary power consumption is prevented by cutting the power and signal lines of the display and related circuits. To this end, in the present invention, it is necessary to determine whether the speaker part is placed near or close to the ear and detect a call state. In the case of a call, it solved by using the call setting information from the communication modem, and in the case of distance discrimination, the infrared transmitter / receiver was used to discriminate.

1 is a block diagram of the subject innovation

(A) Call detection unit: Determines whether a call is made or attempts to make a call to the mobile terminal, and outputs signal 1 as a logic signal " 1 "

(B) Panel control unit: Turns off the panel display by outputting a control signal as signal 3 when busy and close. That is, when the signal 1 of the call detector is the logic signal "1" and the distance discriminator output is the logic signal "1", the power supply and the signal line are cut so as not to operate the panel display. On the contrary, when any one of the signal 1 and the signal 2 is changed to the logic signal " 0 ", the control signal is output so that power and a signal are applied to the panel display so as to be a normal display.

(C) Distance discriminating unit: If the handset is in contact with or near the ear, it is determined and outputs signal 2 as logic signal "1". That is, if the signal 2 is a logic signal "1", the earpiece is close to or in contact with the ear. On the contrary, if the logic signal "0", the handset is far from the ear.

(D) Panel display part: A part that displays visual information of a mobile terminal, and mainly displays text and video information. If the control signal 3 is "1" as the logic signal from the panel controller, the character and image are displayed normally. If the control signal 3 is "0", the display is cut and the operation of the associated circuit is stopped.

The present invention is to determine whether or not a call is made to the mobile terminal to make a call or to make a call and outputs signal 1 as a logic signal "1" to provide a (1) call detection unit, the user is busy and speaker (B) Panel control unit that turns off the panel display by outputting a control signal when the distance between the ear and the ear is close. (C) Distance discriminating unit and moving output by the logic signal "1" when the receiver is in contact with or near the ear. Referring to FIG. 1, an operation of a power consumption control apparatus for a mobile terminal including a panel display unit which mainly displays text and image information as a part of displaying visual information of a terminal is described.

When cutting the display operation, (a) the call detection unit outputs a signal 1 indicating that the call is being made after a call is made or a call is made as a logic signal " 1 " Is a logic signal " 1 " indicating that the speaker is close to the ear, (b) the panel controller outputs a control signal signal 3 that cuts the power supply and the signal as the logic signal " 1 "

On the contrary, when restoring the display back to the normal state, (A) If the output of the call detection unit is a logic signal "0" or (C) The output of the distance discriminator is a logic signal "0", (B) The panel control unit The panel display is normally operated by outputting the control signal 3 as the logic signal " 0 " to restore the operation. That is, if the speaker is removed from the ear during a call or during a call, the display returns to normal.

In addition, when receiving with handsfree or earphone without opening the lid of the mobile terminal, the display operation is not performed as in the prior art.

When the present invention is applied to the mobile terminal, it is possible to increase the battery usage time of the mobile terminal by preventing unnecessary power consumption caused by the display during the call.

Claims (2)

To avoid unnecessary power consumption by turning off the display when the terminal is in communication with the ear, the call detection unit detects that the terminal is busy and the distance discriminator and mobile terminal close to the ear to determine whether the user is holding or placing the handset near the ear. Power consumption control device of mobile terminal, which is composed of panel control unit to turn off the operation of panel display when it is located and talking To avoid unnecessary power consumption by turning off the display when the terminal is in communication with the ear, the call detection unit detects that the terminal is busy and the distance discriminator and mobile terminal close to the ear to determine whether the user is holding or placing the handset near the ear. A mobile terminal consisting of a panel control unit which locates and turns off the operation of the panel display when in a call.
