Embodiments of the present invention relate to a method and apparatus for activating a reflective display screen or a main display screen in a device with a cover attached thereto.

In the case of a mobile device, a cover is usually attached to protect the main display screen. Therefore, in order to improve the usability of the cover, a reflective display screen may be attached to the inside or the outside of the cover.

However, the reflective display screen attached to the cover need not always be activated. The reflective display screen attached to the cover is effective only in terms of power management when it is exposed to the outside and is activated only when the user can see it.

Also, since the main display screen is exposed to the outside only when the cover is opened, it is efficient in terms of power management that the main display screen is activated only when the cover is opened.

Accordingly, there is a need for an effective method of activating the display screen so that the screen can be activated only when necessary depending on the situation of the reflective display screen and whether the cover is opened or not.

A method of activating a context-sensitive display screen in a device with a cover and a device for performing the method are provided. The device can determine whether the display screen needs to be activated by using an illuminance sensor, a gravity direction detection sensor, a proximity sensor, or the like. By automatically adjusting the activation of the display screen on a case-by-case basis, an enhanced effect is expected, especially with respect to power management.

In addition, if the reflective display screen or the main display screen is activated only when necessary, the user may be interested in the display.

According to a first aspect of the present invention, there is provided a method of operating a reflective display screen in a device with a cover, the method comprising the steps of: determining whether a reflective display screen is exposed to the outside step; Determining whether the illuminance detected by the illuminance sensor is higher than a predetermined reference; And activating the reflective display screen when it is determined that the reflective display screen is exposed to the outside and the sensed illuminance is higher than a predetermined reference.

Determining whether the reflective display screen is exposed to the outside includes determining whether the reflective display screen is located at a position visible when the cover is closed; And determining whether the cover is closed. If it is determined that the reflective display screen is positioned at a position where the cover is closed, and it is determined that the cover is closed, it is determined that the reflective display screen is exposed to the outside .

It is preferable that the step of determining whether the cover is closed determines whether the cover is closed by using a proximity sensor or a hall sensor.

Determining whether the reflective display screen is exposed to the outside includes determining whether the reflective display screen is located at a position visible when the cover is closed; And determining whether the cover is closed. If it is determined that the reflective display screen is located at a position where it is invisible when the cover is closed, and if it is determined that the cover is open, it is determined that the reflective display screen is exposed to the outside .

Determining a direction of gravity; And determining whether the reflective display screen is oriented to the bottom using the determined gravity direction, wherein activating the reflective display screen is performed only when the reflective display screen is determined not to be directed to the bottom, It is desirable to activate the display screen.

It is desirable that the predetermined criterion is lowered as the intensity of light that the illuminance sensor can detect when the cover is closed is weaker.

It is preferable that the illuminance sensor is located at a position where it is exposed to light even when the cover is closed.

The location exposed to light is the side of the device, the hole inside the sound from the speaker, the outer side of the cover, the cover closed, the material through which the light is transmitted, the back of the used area, or the light path It is preferable that the light is a part to which light is transmitted.

It is preferable to further include a step of deactivating the reflective display screen when it is determined that the reflective display screen is not exposed to the outside or the detected illuminance is lower than a predetermined reference.

When the reflective display screen is inactivated, it is preferable that the update of the reflective display screen does not operate.

The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Also, in this specification, the terms first, second, etc. may be used to describe various elements, but the elements are not limited by terms. Terms may be used for the purpose of distinguishing one component from another.

Furthermore, the singular forms "a", "an," and "the" include plural referents unless the context clearly dictates otherwise.

Further, in this specification, the display can be understood as a concept including a display screen.

Also, in this specification, the reflective display screen is positioned in a position where it is visible when the cover is closed, including the case where the reflective display screen is attached to the outer side of the cover.

In this specification, the reflective display screen is positioned at a position where it is invisible when the cover is closed. The reflective display screen is attached to the inner side of the cover to display the main display screen and the reflective display screen in a dual mode .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. have.

1A is a diagram illustrating a device 100 when the reflective display screen 110 is located at a position visible when the cover is closed according to an embodiment of the present invention.

In this specification, the reflection type display may mean a display in which information is displayed using external light (external light) without a separate light source. Reflective displays use external light, so they can have good external visibility and low power consumption.

The reflective display screen 110 may be located at a position visible when the cover of the device 100 is closed. Accordingly, even when the main display screen 120 is inactivated when the cover of the device 100 is closed, the reflective display screen 110 is activated to provide various information to the user.

1B is a diagram illustrating a device 100 when the reflective display screen 110 is located in an invisible position when the cover is closed according to an embodiment of the present invention.

When the reflective display screen 110 is positioned at a position where it is invisible when the cover is closed, it may mean that the reflective display screen 110 is located on the inner side of the cover. When the reflective display screen 110 is located on the inner side of the cover, the device 100 may operate so that both the main display screen 120 and the reflective display screen 110 are activated when the cover is opened. In addition, when the cover is closed, the device 100 may be operated such that both the main display screen 120 and the reflective display screen 110 are inactivated.

Disabling the reflective display screen 110 may mean that the update of the reflective display screen 110 is not working.

2 is a flowchart illustrating an example of determining whether the reflective display screen 110 is exposed to the outside and activating the reflective display screen 110 by sensing the illuminance according to an embodiment of the present invention.

In step S210, the device 100 may determine whether the reflective display screen 110 is exposed to the outside. Exposure to the outside generally means a situation in which the reflective display screen 110 can be recognized from the outside in view of the situation in which the device 100 is used.

For example, when the reflective display screen 110 is positioned at a position where the cover is closed and when the cover is closed, it can be determined that the reflective display screen 110 is exposed to the outside. That is, if the reflective display screen 110 is located outside the cover and the cover is closed, the device 100 may determine that the reflective display screen 110 is generally viewable by the user.

Or the reflection type display screen 110 is located at a position where it is invisible when the cover is closed. When it is determined that the cover is opened, it can be determined that the reflection type display screen 110 is exposed to the outside. That is, if the reflective display screen 110 is located inside the cover and the cover is opened, the device 100 can determine that the reflective display screen 110 is generally viewable by the user.

Further, the judgment as to whether the cover is closed can be judged by using the proximity sensor or the hall sensor. The proximity sensor may refer to a sensor for determining whether or not a sensing material has entered the sensing distance. In addition, Hall sensor can be a sensor that uses a hall effect in which a voltage is generated in a direction perpendicular to a current and a magnetic field when a magnetic field is applied to a conductor through which current flows. The Hall sensor can also determine whether the cover is closed using the Hall effect.

In step S220, it is possible to determine whether the illuminance detected using the illuminance sensor is higher than a predetermined reference. The predetermined criteria may vary depending on the situation. That is, as the intensity of the light that the illuminance sensor can detect when the cover is closed becomes weaker, the predetermined standard may be lowered. For example, when the cover is closed so that the path through which the light enters is narrow and the intensity of the light reaching the illuminance sensor is weak, a predetermined criterion can be set so that the predetermined criterion is lowered so that the device 100 operates more sensitively to the light .

In step S230, the device 100 determines that the reflective display screen 110 is exposed to the outside, and activates the reflective display screen 110 when it is determined that the sensed illumination is higher than a predetermined reference.

That is, when the reflective display screen 110 is exposed to the outside in a bright environment, the reflective display screen 110 is activated, and the device 100 can provide information to the user. If there is no surrounding light, such as when the device 100 is in a bag or when the surroundings are dark at night, the user is displayed on the reflective display screen 110 even if the reflective display screen 110 is activated I can not recognize the information. The reflective display screen 110 can not recognize the contents displayed in the reflective display screen 110 when there is no ambient light unlike the main display screen 120. [ Thus, the device 100 may deactivate the reflective display screen 110 if the surroundings are dark and the user can not recognize the contents of the reflective display screen 110.

However, if the reflective display screen 110 is located on the inside of the cover and the cover is closed, even if the surroundings are bright, then the device 100 may not be able to see the reflective display screen 110, Type display screen 110 can be inactivated. The reflective display screen 110 is located outside the cover and the user can generally not see the reflective display screen 110 even when the cover is opened. 110 may be deactivated.

However, if it is determined that the reflective display screen 110 is not exposed to the outside or the detected illuminance is lower than the predetermined reference, the reflective display screen 110 may be inactivated. This will be described later in more detail with reference to FIG.

FIG. 3 is a flow chart illustrating a method of determining whether a device is located at a position where the reflective display screen 110 is visible when the cover is closed according to an exemplary embodiment of the present invention, A flowchart for explaining an example of determining whether or not exposure has been performed.

In step S310, the device 100 determines whether the reflective display screen 110 is located at a position where it is visible when the cover is closed. That is, whether the reflective display screen 110 is located inside or outside the cover. When the cover is closed or opened according to the position of the reflective display screen 110, whether or not the reflective display screen 110 is exposed to the outside differs, so that the reflective display screen 110 is preferentially located The device 100 determines. Which of the reflective display screen 110 is located may be already set in the manufacturing stage of the device 100. However, if the reflective display screen 110 can be detached and attached, the position of the reflective display screen 110 can be continuously detected and used.

In step S320, the device 100 determines whether the cover is closed. When the cover is closed, it may mean that the cover contacts the main display screen 120. Or when the cover is closed, it means that the cover is closed at a certain angle or more.

Further, the judgment as to whether the cover is closed can be judged by using the proximity sensor or the hall sensor. The proximity sensor may refer to a sensor for determining whether or not a sensing material has entered the sensing distance. In addition, Hall sensor can be a sensor that uses a hall effect in which a voltage is generated in a direction perpendicular to a current and a magnetic field when a magnetic field is applied to a conductor through which current flows. The Hall sensor can also determine whether the cover is closed using the Hall effect.

In step S330, it is determined that the device 100 is located at a position where the reflective display screen 110 is visible when the cover is closed. When it is determined that the cover is closed, the reflective display screen 110 is exposed .

4 is a flowchart illustrating a method of determining whether the reflective display screen 110 is positioned at a position where the reflective display screen 110 is closed when the cover is closed and determining whether the reflective display screen 110 is exposed to the outside In which the device 100 determines that the device 100 is a device. Referring to FIG. 4, the method of activating the display screen according to the present embodiment is performed in a time-series manner in the screen activation method shown in FIG. Therefore, the contents described above with respect to the screen activation method shown in FIG. 3 are applied to the screen activation method according to the present embodiment, even if omitted below. 4 differs from FIG. 3 in the step S430, so that the same contents will be briefly described, and differences will be mainly described.

Steps S410 to S420 correspond to steps S310 to S320.

In step S430, it is determined that the device 100 is located at a position where the reflective display screen 110 is not visible when the cover is closed. When it is determined that the cover is open, the reflective display screen 110 is exposed .

That is, steps S330 and S430 may be regarded as a method of determining whether the reflective display screen 110 is exposed to the outside.

It can be seen that the reflective display screen 110 is positioned at a position where it is visible when the cover is closed, as the reflective display screen 110 is attached to the outer surface of the cover. When the reflective display screen 110 is attached to the outer surface of the cover, the reflective display screen 110 may be exposed to the outside when the cover is closed. Normally, the outer side of the cover is exposed to the outside when the cover is closed, and can be seen in a state that can be recognized by the user.

Or the reflective display screen 110 is positioned at a position where it is visible when the cover is opened, it can be seen that the reflective display screen 110 is attached to the inner surface of the cover. When the reflective display screen 110 is attached to the inner surface of the cover, the reflective display screen 110 may be exposed to the outside when the cover is opened. In general, when the cover is opened, the inside of the cover is exposed to the outside, and the user can recognize the cover.

5 is a flowchart illustrating a method of determining whether the reflective display screen 110 is exposed to the outside according to an exemplary embodiment of the present invention and determining whether the reflective display screen 110 is not facing the bottom And is a flowchart for explaining an example of activating the reflective display screen 110. Fig.

In step S510, the device 100 determines whether the reflective display screen 110 is exposed to the outside.

When the reflective display screen 110 is attached to the outer surface of the cover and the cover is closed or when the reflective display screen 110 is attached to the inner surface of the cover and the cover is open, ) Is exposed to the outside.

In step S520, the device 100 may determine whether the illuminance sensed by the illuminance sensor is higher than a predetermined reference.

The predetermined criterion may vary depending on the sensitivity of the illuminance and the intensity of the light sensed by the illuminance sensor when the cover is covered. The predetermined criterion can be set by the user.

In step S530, the device 100 can determine the gravitational direction. More specifically, the device 100 can determine the direction of gravity using a gyro sensor or the like.

In step S540, the device 100 may determine whether the reflective display screen 110 is facing the bottom using the determined gravity direction. Whether the reflective display screen 110 is located on the outside of the cover, whether the cover is open or not, and the determined gravity direction.

For example, when the reflective display screen 110 is located outside the cover and the cover is closed, if the front direction and the gravity direction of the device 100 are the same, the reflective display screen 110 is determined to be facing the bottom .

Or if the reflective display screen 110 is located outside the cover and the cover is open and the front direction and gravity direction of the device 100 are the same, then the reflective display screen 110 may not be facing the floor have.

Or if the reflective display screen 110 is located inside the cover and the cover is open and the front direction and gravity direction of the device 100 are the same, then the reflective display screen 110 may be determined to be facing bottom .

Or when the reflective display screen 110 is located inside the cover and the cover is closed and the front direction and the gravity direction of the device 100 are the same, it is determined that the reflective display screen 110 is not facing the floor have.

In step S550, the device 100 can activate the reflective display screen 110 only when it is determined that the reflective display screen 110 is not facing the bottom.

There may be a case where the illuminance sensor recognizes the illuminance even when the reflective display screen 110 faces the floor as when the illuminance sensor is located on the side of the device 100. [ The device 100 may activate the reflective display screen 110 only when it is determined that the reflective display screen 110 is not facing the bottom, taking into account the direction of gravity as well. FIG. 5 is a flowchart illustrating an example in which a device determines whether a reflective display screen 110 is exposed to the outside according to an embodiment of the present invention, detects illumination and, in some cases, deactivates a reflective display screen.

Referring to FIG. 6, the method of activating the display screen according to the present embodiment is performed in a time-series manner in the screen activation method shown in FIG. Therefore, the contents described above with respect to the screen activation method shown in FIG. 2 are also applied to the screen activation method according to the present embodiment even if omitted below. 6, there is a difference that is added to step S640 in comparison with FIG. 2. Therefore, the same contents will be briefly described, and differences will be mainly described.

Steps S610 to S630 correspond to steps S210 to S230.

Step S640 is a step of deactivating the reflective display screen 110 when it is determined that the reflective display screen 110 is not exposed to the outside or the sensed illuminance is lower than a predetermined reference.

If it is determined that the reflective display screen 110 is not exposed to the outside, the user does not recognize the information displayed on the reflective display screen 110 even if the reflective display screen 110 is activated. Accordingly, when it is determined that the reflective display screen 110 is not exposed to the outside, it is effective to deactivate the reflective display screen 110 in relation to power management. Accordingly, when it is determined that the reflective display screen 110 is not exposed to the outside, the reflective display screen 110 is deactivated.

In addition, when the sensed illuminance is lower than a predetermined reference, the user can not acquire information from the reflective display screen 110. The user can recognize the information from the reflective display screen 110 only when the surrounding light is present. This is because the reflection type display screen 110 is generally free from light. Accordingly, when the sensed illuminance is lower than a predetermined reference, the device 100 deactivates the reflective display screen 110 regardless of whether the reflective display screen 110 is exposed to the outside.

7 illustrates an example of activating the main display screen 120 when the cover determines that the cover covers the main display screen 120 and the device does not cover the main display screen 120 according to an embodiment of the present invention Fig.

The device 100 determines whether the cover covers the main display screen 120 in step S710. Whether or not the cover covers the main display screen 120 can be determined by determining whether it is within a predetermined standard by using a distance between the cover and the main display screen 120 or a closed angle of the cover.

The device 100 deactivates the main display screen 120 when the cover covers the main display screen 120 in step S720.

Since the backlight is operated on the main display screen 120, the user can acquire information from the main display screen 120 even when the illuminance around the periphery is low. Accordingly, the device 100 determines whether or not the main display screen 120 is activated by determining whether the cover covers the main display screen 120 or not. More specifically, when the cover covers the main display screen 120, the device 100 disables the main display screen 120 because the user can not recognize the information from the main display screen 120.

The device 100 activates the main display screen 120 if the cover does not cover the main display screen 120 in step S730. More specifically, when the cover does not cover the main display screen 120, the device 100 can activate the main display screen 120 because the user can recognize the information from the main display screen 120 regardless of illumination.

8 is a flow chart illustrating a method of determining whether to activate the reflective display screen 110 and the main display screen 120 by determining whether the cover is closed, whether the illuminance exceeds a predetermined standard, or the like, according to an embodiment of the present invention Fig. 8 is a flowchart illustrating an example.

8, it is assumed that the reflective display screen 110 is positioned at a position where the cover is closed, that is, when the reflective display screen 110 is attached to the outer side surface of the cover.
