Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile phone having a screen saver function for a display screen, particularly a power saving screen saver function.

[0002]

2. Description of the Related Art In the display section of a CRT display screen of a personal computer, when the same screen is displayed for a long time, the light-emitting material in the brightly shining part deteriorates, causing seizure, and turning off the power of the display However, the trace of the same screen may remain. In order to prevent such burn-in of the display unit, when no operation signal is input to the processing device for a certain period of time, the display on the display is turned off, and various patterns are moved around on the screen so that burn-in does not occur. At the same time, a screen saver function that automatically darkens the screen is used.

In this screen saver function, the execution waiting time of the screen saver is set in advance,
When there is no input to the processing device within the execution waiting time of the screen saver, the screen of the display unit is switched from the processing screen corresponding to the processing operation of the processing device to the screen saver screen.

In the screen saver function, when an operation input signal is input to the processing device while the screen of the display unit is switched to the screen saver screen, the screen pattern of the display unit immediately disappears automatically, and the screen saver screen is displayed. To the processing screen.

In addition, the screen saver function can be used for security data protection because the processing screen that has been operated until now can be hidden by switching to the screen saver screen when the operation is interrupted. ing.

[0006] A mobile phone is also generally equipped with a screen saver function, and in order to activate this screen saver function, it is necessary to continue a state in which there is no input to the mobile phone for a certain time, for example, several minutes or more. .
The time of several minutes varies depending on the model, and in general, it is possible to set the time until the screen saver function operates within a certain range according to the preference of the user. However, in any case, a certain time is required until the screen saver is activated.

On the other hand, in a mobile phone, in order to extend the continuous use time that can be used by charging the battery once, it is always required to reduce the power consumption of the device. Therefore, if the mobile phone is configured to be placed in a low power consumption state by activating the screen saver, the screen saver function of the mobile phone is an effective function for realizing low power consumption of the device. .

[0008]

However, as described above, by the time the screen saver function is activated,
It is necessary to continue the state where there is no input for a fixed time set in advance, for example, several minutes or more. During this period, the screen saver function is not activated, and reduction in power consumption cannot be expected. On the other hand, if the time until the screen saver function is activated is set to be extremely short, the screen saver function will be inadvertently activated during use of the mobile phone, and processing for a call or other purposes will be interrupted. The possibility is increased and the operation efficiency is significantly lowered, which is not preferable.

It is an object of the present invention to provide a mobile phone having a screen saver function that can effectively control the screen saver function operating in the power saving mode.

[0010]

In order to achieve the above-mentioned object, a mobile phone according to the present invention is a mobile phone having a screen saver function, wherein the screen saver function is in a standby state in which there is no input. It is activated when it continues for a predetermined time or more, and is activated immediately by inputting a predetermined screen saver activation key at any time.

Also, the screen saver function is activated by a key input for designating activation of the screen saver without waiting for a preset certain time, and the screen is shifted from the standby screen to the screen saver screen.

Further, the screen saver function keeps the operation of the application in an end state when it is placed in the activated state, limits the display color of the display screen, and automatically darkens the display screen to reduce consumption. It operates with electric current.

Further, the mobile phone has a key lock function for setting to invalidate the key input, and as one of the predetermined screen saver activation key inputs, the screen saver is immediately activated by using the key lock setting input. The screen can be activated, and instead of the arbitrary key input, a key unlock setting input returns the screen saver activated state to the standby state.

A personal code can be added as the predetermined screen saver activation key input, and the personal code is input instead of the arbitrary key input to return from the screen saver activation state to the standby state. Is.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a mobile phone having a screen saver function according to the present invention will be described below with reference to the drawings. In the screen saver function of the mobile phone according to the present invention, once the screen saver function is activated, the operation of the application is maintained, the display color of the display screen is limited, and the display screen is automatically darkened. As a result, it becomes possible to significantly reduce the current consumption.

Also in the mobile phone according to the present invention, as the original function of the screen saver, as in the case of the conventional screen saver, the function which is activated when a state without any input continues for a predetermined time or more is unchanged. Have A feature of the present invention is that the screen saver can be immediately activated at any time by the activation key input by the user. That is, when the user determines not to use the application, the activation instruction is input and the screen saver can be activated.

Therefore, the screen saver can be activated immediately after the user finishes inputting the process without waiting for the preset time to elapse,
Compared with the conventional one, it is possible to shift to a low current consumption operation earlier.

(First Embodiment) The first embodiment of the present invention will be described below.
The embodiment will be described with reference to FIG.

Conventionally, in order to activate the screen saver, as shown in the screen transition of FIG. 1, there is no input to the mobile phone displaying the standby screen 1 for a predetermined time. Sometimes the screen saver works and is activated, and the standby screen 1
Shifts to the screen saver screen 2. The form of this screen transition is the same in the present invention.

In contrast to this mode of screen transition, in the present invention, as shown in the screen transition of FIG. 2, the screen saver is input by a key input for designating the activation of the screen saver of the user without waiting for a certain set time. To start
As a result, the standby screen 1 can be switched to the screen saver screen 2. Therefore, the screen saver can be switched at an early stage regardless of the preset waiting time.

The state transition diagram of FIG. 3 shows the control procedure relating to the screen transition between the standby screen 1 and the screen saver screen 2 according to the present invention described above. In FIG. 3, the state in which the standby screen is displayed is composed of two states, that is, the clocking initialization state S1 and the clocking state S2. The state in which the screen saver screen is displayed is represented by the screen saver activation state S3.

The details of the operation will be described below with reference to FIG. When the mobile phone enters the standby state, it once enters the timekeeping initialization state S1, initializes the timekeeping means for measuring the standby time for activating the screen saver, and then immediately transitions to the timekeeping state S2 by the transition path P1. , Start timing. When any input is detected during the timekeeping in the timekeeping state S2, the transition path P2 caused by the occurrence of the input returns to the timekeeping initialization state S1 to initialize the timekeeping means, and then restarts the timekeeping in the timekeeping state S2. Resume.

When the time measurement result in the timekeeping state S2 has passed for a preset time, the screen saver is activated via the transition path P4 according to the elapse of the set time to shift to the screen saver activation state S3. On the other hand, the time counting state S
When the user executes the activation key input designating the activation of the screen saver when the time measurement result in 2 does not expire the preset time, the transition path P5 of the activation key input immediately causes the time counting state S2 to be changed. The transition to the screen saver activation state S3 is performed.

In the return from the screen saver activation state S3 to the standby state, transition to the timekeeping initialization state S1 follows the transition path P3 triggered by the occurrence of some key input as in the conventional case.

In FIG. 3, since the timekeeping initialization state S1 immediately shifts to the timekeeping state S2 only by executing the process of initializing the timekeeping means, in the standby state, the portable telephone is virtually always timekeeping. Remains in state S2. Therefore, by executing the activation key input for designating activation of the screen saver in the timekeeping state S2, the user can immediately shift to the screen saver screen when the processing by the application is completed, and the mobile phone can be efficiently used. It becomes possible to perform power saving operation.

(Second Embodiment) The second embodiment of the present invention will be described below.
The embodiment will be described with reference to FIG.

In the first embodiment, after shifting to the screen saver screen, as shown in FIG. 3, the screen saver is stopped by an arbitrary key input P3, and the mobile phone immediately returns to the standby state. However, depending on the implementation of the mobile phone, etc., it is possible that a key input occurs unexpectedly during carrying, and this causes the screen saver to stop and return to the standby state. The power saving control by the screen saver cannot be effectively used. In order to prevent this kind of erroneous input, a mobile phone may use a key lock function. When the key lock function is set, unless the key is unlocked, if the key input P3 in FIG. 3 is not validated, the screen saver will not be inadvertently stopped.

In the mobile phone having the key lock function, the user sets the key lock function when the user finishes the process and the screen saver may be activated immediately. Therefore, it is advantageous to directly activate the screen saver by the key lock setting input as in the activation key input P5 as shown in FIG. In this case, it is possible to return to the standby state by setting the execution of the key unlock setting input as the transition path P3.

(Third Embodiment) The third embodiment of the present invention will be described below.
The embodiment will be described with reference to FIG.

When the screen saver is activated by the activation key input P5 of FIG. 3 in the first embodiment, a personal code can be added as an activation key input as shown in FIG. In this case, the transition path P3 that stops the screen saver and returns to the standby state becomes valid by the input of the personal code.

With this, it is possible to reduce the possibility that the screen saver is stopped due to an unexpected key input during carrying, and it is possible to use the mobile phone without permission even without permission. It is possible to prevent it, save power, and expect security effects.

[0032]

As described above, according to the present invention, when the screen saver is activated, the operation of the application is maintained in the terminated state, the display screen of the mobile phone is automatically darkened, and the display color of the screen is restricted. By doing so, it is possible to start the screen saver immediately when it is determined that the user does not need to operate the application in advance, so that the current consumption can be reduced.
As in the conventional case, the switching time to the power saving operation is shortened by the set time required until the screen saver is activated, and the current consumption can be reduced.

When it is not necessary to operate the application as in the conventional key lock state, the low power operation can be stably maintained by immediately starting the power saving screen saver.

Furthermore, the screen saver function is stopped,
By performing the control to shift to the standby state in response to the input of the personal code, it becomes possible to realize the security function as well as the power saving function.
