Description

{Method for displaying of battery residue or receive sensitivity in portable terminal}

The present invention relates to a method of displaying the remaining battery capacity and reception sensitivity of a portable terminal for displaying the available time and reception sensitivity of the portable terminal as digital numbers, in particular, the current required when waiting for the current used by the terminal itself, the current required during a call , Current required for game, current required for Internet use, current required for listening to music, etc., and digitally and digitally display the available time and reception sensitivity corresponding to each type in consideration of current battery level and reception sensitivity. The present invention relates to a method of displaying a battery level and a reception sensitivity of a portable terminal to be displayed on a display unit (LCD).

In general, terminals (particularly, mobile communication terminals and WLL terminals) use secondary rechargeable batteries such as nickel hydrogen and lithium ions to ensure mobility. Such a terminal battery gradually consumes a little charged current even when it is not used due to its characteristics, which is called a self-discharge. Because of this, the user should always be concerned about whether the battery is remaining. This is to prevent the battery from being discharged while the terminal cannot be used. To this end, the terminal displays the remaining battery level as an icon on a liquid crystal display (LCD) so that the user can easily determine the remaining battery level.

1 is a view showing the configuration of a battery remaining display device in a typical portable terminal.

As shown therein, the voltage output from the battery 50 is input to the analog / digital converter 20 through the multiplexer 30. The analog / digital converter 20 converts the input voltage signal into a digital signal and outputs the digital signal to the controller 10. Then, the control unit 10 receives the digitally converted signal and compares it with a threshold stored in the memory and displays the low battery as a low battery on the display unit 60. Here, the temperature sensor 40 is used in the case of increasing the accuracy by measuring the temperature of the portable wireless communication terminal because the state of the battery in the portable wireless communication terminal changes with temperature.

In addition, the multiplexer 30 multiplexes two or more signals input under the control of the controller 10. In addition, the controller 10 includes a memory that stores an overall execution program of the portable wireless communication terminal and controls the terminal as a whole by the program.

On the other hand, the portable wireless communication terminal as described above differs in current consumption depending on the sleep mode, the standby mode, and the call mode.

This will be described with reference to FIG. 2.

2 is a view illustrating a discharge curve of a rechargeable battery and a battery remaining amount display method according to the discharge curve in a typical portable terminal.

Typically, the rechargeable battery has a discharge characteristic according to the discharge curve. 2 (a) shows the discharge characteristics according to the discharge curve of the rechargeable battery. 2 (b) shows a conventional battery remaining amount display method.

As shown in FIG. 2, the discharge curve is divided into three regions of A, B, and C as shown in FIG. 2A. Therefore, the remaining battery indicator is divided into three sections, such as the first region, the second region, and the third region, according to each division of the discharge curve as shown in (b) of FIG. 2. Of course, depending on the characteristics of the terminal manufacturer may be divided into 4 to 6 display.

In the general portable terminal as described above, the battery capacity and reception sensitivity are simply divided into three to six levels and displayed on the liquid crystal display (LCD) in an approximate amount. Therefore, in the case of displaying the remaining battery by dividing the discharge curve as shown in FIGS. 2 (a) and 2 (b) by three, there is an unreasonable problem of displaying the last step even when the battery is almost exhausted. . For this reason, since the user cannot accurately know the waiting time for the call or the available time for the remaining battery level, the call is frequently disconnected.

In addition, in the conventional case, since there is no function of displaying the usable time, the user may roughly recognize the usable time of the battery based on the user's experience. In this case, the battery remaining time and the usable time may not be accurate. Problems such as time and economical waste such as charging in the case of being able to use without a charge, and sudden disconnection during the use of the terminal due to the non-charging even in the situation of charging have occurred.

Accordingly, the present invention is proposed to solve the above problems of the prior art,

An object of the present invention is to divide the current used by the terminal itself into the types of current required for standby, current required for communication, current required for gaming, current required for using the Internet, current required for listening to music, etc. By considering the sensitivity, the available time and reception sensitivity corresponding to each type are displayed digitally numerically on the liquid crystal display (LCD), so that the user can easily understand the available time that they want to know. The present invention provides a method for displaying a battery level and a reception sensitivity of a portable terminal so that the reception area and the reception area can be easily determined.

The present invention for achieving the above object,

Calculating a remaining capacity of the battery by checking a current voltage of the battery;

3 is a flowchart illustrating a numerical display method of usable time and reception sensitivity in a portable terminal according to the present invention.

As shown therein, a step of checking the battery voltage in software (ST11), a step of calculating the remaining amount of battery with the checked voltage value (ST12), and a step of calculating the data value after checking the terminal reception sensitivity ( ST13), comparing the calculated data value with a predetermined terminal self-consumption current value (ST14), calculating the available time according to the functional state according to the comparison (ST15), and the calculated use And displaying the possible time and the reception sensitivity as digital values on the liquid crystal display.

The battery level and reception sensitivity display method of the portable terminal according to the present invention which performs such operation will be described in more detail as follows.

First, in step ST11, the voltage of the battery is checked using software implementing the above functions in the terminal, and the remaining battery level is calculated in step ST12. In step ST13, the terminal reception sensitivity is checked and the data value is calculated. Next, in step ST14, the calculated data value is compared with a terminal self consumption current value such as a predetermined LCD consumption current, standby consumption current, LED consumption current, speaker and receiver consumption current values, and the calculated reception sensitivity data. The available time according to the functional state is calculated in step ST15 using the value and the self consumption current value.

In this case, the available time may be calculated by showing a desired value of the consumer, and as an example, the available time may be displayed such as a callable time, a standby time, a game available time, an internet available time, and a music listening time.

Next, in step ST16, the usable time and reception sensitivity values obtained through the above process are digitized and digitally displayed on the liquid crystal display so as to be easily understood by the user. Here, the available time displays the desired time according to the user selection among the functions.

Meanwhile, the terminal self consumption current value is previously input to the terminal memory as follows.

That is, the voltage characteristic value of the battery used in the terminal is input into the memory, the current consumption amount when the terminal is in the standby state is input into the memory, and the components of the terminal (LED, EL, LCD, speaker, receiver, motor, etc.) The current consumption according to the use is input to the memory, the current consumption in the standby state of the terminal considering the reception sensitivity is input into the memory, and the current consumption in the call state of the terminal considering the reception sensitivity is input into the memory.

In this case, the current consumption is calculated according to the reception sensitivity of the terminal according to the display method of the available time according to the function state input by the user, and the standby time, talk time, game time, Internet time In addition, the available time may be displayed as a digital value by a method such as a music listening time, and the present reception sensitivity of the terminal is converted into a digital value.

According to the above-described "digital display method of the portable terminal" of the present invention, the user can display the expected usable time and reception sensitivity of his terminal as an accurate digital value to facilitate the user's convenience when using the terminal, and By digitizing the value has the advantage that can take advantage of the high-end terminal.

In addition, if you need to use the battery for a long time when the remaining battery capacity is not much, by minimizing the function of the terminal, the usable time can be increased, and the user can check the digital value numerically by visually checking the usable time according to the functional state of the terminal. By increasing the ease of use, the current consumption increases in the state and region where the reception sensitivity is low, there is an advantage that can increase the usable time by turning off the power of the terminal in the low reception sensitivity.
