Display Mounting Apparatus And The Method Thereof}

The present invention relates to a display mounting apparatus and a display mounting method. Specifically, the present invention relates to a display mounting apparatus and a display mounting method for changing the angle of the display to protect the user's vision when the distance between the display and the user is close to allow the user to use the display at an appropriate distance.

The spread of electronic devices including displays, for example, smart phones, tablets, notebooks, and the like, is expanding, and the range of users using such electronic devices is also increasing. In particular, the prevalence of low-age users is rapidly expanding, and low-age users often move closer to the display during unconsciousness, which may adversely affect the user's vision. For this reason, measures for protecting eyesight of low-age users are actively discussed.

As a conventional method for preventing the deterioration of vision due to viewing the display at a close distance, a method of manipulating the display screen such as changing the screen to a specific image when the distance between the display and the user becomes close is known. There is a problem in that the hardware or software of the containing electronic device itself has to be modified, which is not easy to implement in reality.

Alternatively, a method of cutting off power supplied to the electronic device when the distance between the display and the user is near is known. However, when the method is used in a smartphone or a tablet, the power of the entire electronic device including the display is cut off, which causes a problem of causing damage to the electronic device or loss of data in operation.

Therefore, there is a need to provide a practical and realistic way to solve the problem of vision degradation as the distance between the display and the user gets closer.

1 illustrates a display mounting apparatus according to an embodiment of the present invention. Referring to FIG. 1, the display mounting apparatus 100 (hereinafter, also referred to as a 'mounting device') may include a main body 110, a support 130, and an angle adjuster 150.

The main body 110 may be installed on a floor, a wall, or the like to stably maintain the entire mounting apparatus 100. The body 110 may include a part or the entire configuration of the angle adjuster 150 inside or outside thereof.

The support unit 130 may be connected to the main body 110 while supporting the display. At this time, the support 130 may be connected to the main body 110 in a manner that can be moved relative to the main body 110 so that the display angle is changed. The relative movement of the support 130 with respect to the main body 110 may be rotation, sliding, etc., but is not limited thereto.

The angle adjuster 150 may change the direction in which the display emits light (ie, display angle) by moving the support 130 supporting the display relative to the main body 110. For example, the support may be moved so that the angle between the display light emitting surface and the horizontal plane (the ground plane) is changed, or the display light emitting direction is maintained while the angle at which the display light emitting surface is formed with the horizontal plane is constant (that is, there is no up and down rotation). The support may be moved to rotate in the left or right direction, or both may be used to change the direction in which the display emits light. In order to help the understanding of the function of the angle adjusting unit 150 to change the display angle will be described with reference to the examples of FIGS.

3 (a) illustrates a case where the mounting apparatus 300 maintains the display 10 at a viewing angle, and FIG. 3 (b) illustrates that the mounting apparatus 300 changes the display 10 to an eye protection angle. One case is illustrated.

Referring to FIG. 3 (a), the support part 330 may be connected to the main body 310 through the connection part 320 while supporting the display 10. In FIG. 3A, the light emitting surface of the display 10 supported by the support 330 emits light toward the user's eye 20. The case in which the light emission direction of the display is a good angle for viewing by the user will be expressed as a viewing angle. In FIG. 3A, the line segment DS extending from the display 10 represents a light emitting surface of the display, and the line segment HS represents a direction of a horizontal plane or a ground plane. An angle θ formed between the display emission surface DS and the horizontal surface HS may be an example of the display angle.

FIG. 3B illustrates a case in which the light emitting direction of the display is changed to a direction that is inconvenient for a user to view by rotating the support 330. The display angle in the state in which the user is uncomfortable for viewing will be referred to as the vision protection angle.

As illustrated through FIG. 3, the user moves the support 330 relative to the main body 310 (eg, rotates) to change the emission direction of the display 10 (ie, change the display angle). Maintaining a viewing angle that is good for viewing or forming an eye protection angle that is inconvenient for a user to watch.

FIG. 4 illustrates another embodiment of the mounting apparatus in which the support 430 moves relative to the main body 410 in a sliding manner to change the light emission angle of the display 10. 4A illustrates a case in which the light emission direction of the display 10 maintains an appropriate viewing angle for viewing toward the user's eye 20, and FIG. 4B illustrates that a part of the support part 430 is the main body 410. By sliding relative to), the light emitting direction of the display 10 is changed to an eye protection angle that is not suitable for a user to see. In the example of FIG. 4, the display angle θ may be understood as an angle formed between the display emission surface DS and the horizontal surface HS.

As illustrated through FIG. 4, the user moves the support 430 relative to the main body 410 (eg, slides) to change the light emission direction of the display 10 (ie, change the display angle). Maintaining a viewing angle that is good for viewing or forming an eye protection angle that is inconvenient for a user to watch.

FIG. 5 illustrates another example of the mounting apparatus, and illustrates a case where the mounting apparatus is viewed from above. FIG. 5A illustrates a state in which the display 10 emits light toward the user's eyes 20 while the display 10 is supported by the support 530. In FIG. 5B, the support 530 has the main body 510. In the state supported by), the light emitting direction of the display 10 is changed to be inconvenient for the user to view. It can be understood that the state of FIG. 5 (a) is maintained as the viewing angle, and the state of FIG. 5 (b) is changed to the vision protection angle.

As illustrated through FIG. 5, the user views by changing the emission direction of the display 10 (ie, changing the display angle) by moving (eg, rotating) the support 530 relative to the main body 510. It is possible to maintain a good viewing angle or to create an eye protection angle that is inconvenient for the user to view.

When the embodiment of FIG. 3 is compared with the embodiment of FIG. 5, the embodiment of FIG. 3 and the embodiment of FIG. 5 are similar in terms of rotation of the support part 530, but in the case of the embodiment of FIG. 5, the display light emitting surface is a horizontal plane. The display light emitting surface is rotated in the left and right direction while maintaining a constant angle (for example, a right angle) with respect to the ground of FIG. 5, and the display light emitting surface DS and the horizontal surface HS are formed in the embodiment of FIG. 3. The difference is that they rotate in the direction of changing the angle. In the case of FIG. 5, a display angle may be defined as a direction of the display emitting surface based on a direction toward the front of the mounting apparatus, but a reference may be set differently and a display angle may be defined.

As exemplarily described with reference to FIGS. 3 to 5, various structures may be used for the mounting apparatus, and the display angle may be defined differently according to the structure of the mounting apparatus or the setting of the reference direction. As used herein, the term 'display angle' refers to an angle formed by a reference line or reference plane appropriately set in consideration of a direction in which the light emitting surface of the display rotates according to the movement of the support (eg, rotation or sliding). It can be understood as. In addition, the viewing angle may be understood as an angle suitable for the user to view, and the vision protection angle means a state in which the light emitting surface of the display is moved to an unsuitable or uncomfortable state for the user to watch as the support moves. It can be understood that. However, since the absolute size of the viewing angle and the eye protection angle may vary depending on the reference line / reference plane setting and the user's preferred angle, the difference between the viewing angle and the eye protection angle is more meaningful than the absolute size of the viewing angle and the eye protection angle. This should be understood. The difference between the viewing angle and the eye protection angle may be enough for the user to feel uncomfortable, for example, when it is 30 degrees or more. According to the exemplary embodiment, the difference between the viewing angle and the eye protection angle may be set within a range of 30 degrees to 60 degrees, thereby reducing the user's discomfort and giving alarm. According to the embodiment, the difference between the viewing angle and the vision protection angle may be set to 90 degrees or more to make viewing difficult at a close distance. However, the difference between the viewing angle and the eye protection angle of the present embodiment is not limited to this numerical range.

FIG. 2 illustrates an internal configuration of the angle adjuster of FIG. 1. Hereinafter, the angle adjuster 150 will be described with reference to FIGS. 1 and 2.

The angle adjuster 150 may include a controller 251, a sensor 253, a power unit 255, a user interface 257, and a display 259.

The sensor unit 253 may measure a distance between the display and the user and transmit information about the measured distance to the controller 251. The sensor unit 253 may measure the distance between the display and the user by using an infrared method, but is not limited thereto. The sensor unit 253 may be disposed inside and / or outside the main body 110 and / or the support 130 of the mounting apparatus, or may be disposed in a separate housing.

The power unit 255 may move the support 130 relative to the main body 110 so that the display angle may be changed. The power unit 255 may be disposed inside and / or outside the main body 110 and / or the support 130 of the mounting apparatus, or may be disposed in a separate housing.

The power unit 255 may include a motor and a motor driving unit to provide a force for moving the support unit 130.

According to an embodiment, the power unit 255 may change the display angle by using an elastic body such as a spring. That is, the power unit 255 may change the angle of the display from the viewing mode to the vision protection angle by using an elastic body such as a spring instead of changing the display angle using a motor or the like. Referring to FIG. 4, for example, a force in a sliding direction in the vision protection mode is applied to the support 430 using an elastic body such as a spring (not illustrated), but the user applies the support 430 to FIG. When switching to the viewing angle as shown in FIG. 2, the user maintains the viewing angle set by the user using the locking means, and the control unit controls the locking means when switching from the viewing angle to the eye protection angle, thereby supporting the support 430 through the force of the elastic body. It can operate by sliding to switch to the vision protection angle. In this case, the power unit 255 does not need a configuration such as a motor and a motor driving unit has the advantage that it can be implemented in a simple structure and low cost.

According to an embodiment, the power unit 255 may change the angle of the display using gravity. That is, the power unit 255 may change the display angle from the viewing angle to the vision protection angle by using gravity instead of changing the angle of the display using a motor or an elastic body. For example, as shown in FIG. 4A, the display 10 and the support part 430 may be formed to move at an angle of vision protection by gravity, but in a viewing mode, gravity may be used using a locking means. When the display is prevented from being tilted, the control unit controls the locking means when switching to the vision protection angle so that the support unit 430 and the display 10 are tilted by gravity so that the motor is not used. You can change from viewing angle to vision protection angle without having to. In this case, in order to return the display 10 from the vision protection angle to the viewing angle, the user's force may be utilized. That is, when the mounting apparatus 400 does not include a motor or the like and thus cannot provide a force for returning the display 10 from the vision protection angle to the viewing angle, the user is allowed to return the display 10 to the viewing angle. The mounting device 400 may operate in a manner to control the switching from the viewing angle to the vision protection angle. In this case, the power unit 255 does not need a configuration such as a motor and a motor driving unit has the advantage that it can be implemented in a simple structure and low cost.

Referring back to FIG. 2, the controller 251 may perform an overall control function of the angle adjuster 150. In addition, the controller 251 divides the operation mode based on the distance measured by the sensor unit 253, and controls the display angle adjustment function by controlling the power unit 255 to change the display angle according to the operation mode. Can be done. The display angle adjustment function of the controller 251 will be described in detail with reference to FIGS. 6 and 7 below.

The user interface 257 and the display unit 259 may be used as information exchange means between the user and the mounting apparatus. That is, the user may provide necessary information such as operation setting to the mounting apparatus through the user interface 257, and the mounting apparatus may provide necessary information such as an operation mode and a warning message through the display unit 259.

Configurations of the angle adjuster 150 illustrated in FIG. 2 may be disposed in one housing, but each configuration may be distributed in a required position. In addition, each configuration of the angle adjuster 150 may be disposed inside and / or outside the main body and / or the support, but may be disposed at other third places.

6 illustrates a procedure in which the display mounting apparatus performs the display mounting method. A display mounting method according to an embodiment will be described with reference to FIG. 6.

First, the controller of the mounting apparatus may check whether the user is in a forced operation mode (S610). The forced operation mode does not enter the operation mode according to the mode determination of the controller, but means to enter the operation mode by the user's instruction regardless of the mode determination of the controller. That is, the controller may provide a function for the user to select forced entry into the operation mode. If there is no user forced operation mode selection, the process proceeds to step S660 and if there is no user forced operation mode selection, the process proceeds to step S620.

Meanwhile, although FIG. 6 illustrates that step S610 is performed before the distance measuring step S620, step S610 may be performed later than step S620 or may be performed in no particular order in an interrupt manner. In this case, if the user enters the manipulation mode entry command, the manipulation mode may be entered despite the measured distance.

In operation S620, the sensor unit may measure a distance between the user and the display. Infrared light may be used for distance measurement, but is not limited thereto.

In operation S630, the controller may select an operation mode. The operation mode may include a viewing mode, an operation mode, and an eye protection mode. When the measured distance is greater than or equal to the first distance (that is, more than the distance suitable for viewing) and operates in the viewing mode, and when the measured distance is less than or equal to the second distance smaller than the first distance (that is, the distance for the manipulation of the display). In operation mode, when the measured distance is less than the first distance and the second distance exceeds the limited period (farther than the distance for operation, but too close to the viewing distance) may operate in the vision protection mode.

The vision protection mode may be an additional condition that the measured distance is maintained for at least a first time in the limited period. That is, when the distance is maintained for more than the first time in a state corresponding to the restricted period, the eye protection mode may be operated. The reason for setting the additional time condition when entering the eyesight protection mode is that the user may feel uncomfortable if the user immediately enters the eyesight protection mode when the user enters the restricted section temporarily, but the distance is temporary when the time condition is included. This is because the user's convenience may not be enhanced because the eyesight mode does not operate.

Depending on the mode selected in step S630, it may proceed to any one of step S640, S650 or S660.

If the controller determines the viewing mode in step S630, the process proceeds to step S640 and the viewing mode is entered. In step S642, the controller controls the support unit to adjust the display angle to be the first angle. The first angle may be an appropriate viewing angle for the user to watch the display. 'Adjusting the display angle to be the first angle' can be understood as a concept that includes not only changing the display angle to be the first angle from another angle, but also maintaining the first angle adjusted by the user.

The first angle (viewing angle) may be an angle set by a user through a viewing angle setting function. Since the viewing angle suitable for viewing may be different according to a user or a situation, the mounting apparatus may provide a viewing angle setting function to allow the user to set the viewing angle. As another method of setting the viewing angle, the controller may collect display angle data in the viewing mode and determine the viewing angle using statistical techniques.

If the controller determines that the eyesight protection mode in step S630, the process proceeds to step S650 enters the eyesight protection mode, and in step S652 the control unit can control the support to adjust the display angle to be the second angle. Here, the second angle may be an eye protection angle that is an angle that is inappropriate or inconvenient for the user to watch the display. 'Adjusting the display angle to be the second angle' can be understood as a concept that includes not only changing the display angle from the other angle to the second angle but also maintaining the second angle.

If the controller determines the operation mode in operation S630 or the forced operation mode in operation S610, the controller proceeds to operation S660 to enter the operation mode, and in operation S662, the controller controls the support to adjust the display angle to be the first angle. have. Here, the first angle may be a viewing angle suitable for the user to watch or manipulate the display.

When the viewing angle adjustment is completed in step S662, the process proceeds to step S664, and it may be determined whether a predetermined time (third time) has elapsed without the user's manipulation. When a predetermined time has elapsed without the user's operation, the user can switch from the operation mode to the vision protection mode. The reason for determining whether a predetermined time has elapsed without the user's operation is to prevent the user from disabling the vision protection function. That is, when the user sets the forced operation mode, the user enters the operation mode regardless of the distance between the user and the display, and thus the vision protection mode may not be activated even when the distance between the user and the display is close. Even if the user has set the forced operation mode, this problem can be prevented by switching to the vision protection mode if there is no user operation for a predetermined time. As a method of determining whether there is a user's manipulation, the motion sensor may be used to determine whether the user has a motion for manipulating the display or the degree of change in the distance between the user and the display measured by the distance sensor. Judgment may be made but is not limited thereto.

Next, the procedure of measuring the distance by the display mounting apparatus and classifying the mode will be described in more detail with reference to FIG. 7.

In operation S710, the sensor unit may measure a distance between the user and the display at a predetermined period T0. The distance measurement period may be appropriately set depending on the situation.

In operation S720, the controller may determine whether the measured distance L is greater than the first distance L1. If the measured distance L is equal to or larger than the first distance L1, the process may proceed to step S721 to initialize the variable count1 and the variable count2 to zero. Thereafter, after checking whether the current display angle P is the viewing angle P0 in step S723, if the current display angle P is the viewing angle P0, the flow proceeds directly to step S770, and the current display angle P is viewed. If it is not the angle P0, the process proceeds to step S725 and the display angle is adjusted to the viewing angle, and then the process proceeds to step S770.

Here, count1 is a variable used to determine whether the first time T1 has elapsed when entering the vision protection mode, and count2 is the second time T2 and the third time (T2). Compared with T3), this variable is used to send a warning message or switch the mode when the operation mode is prolonged. In watch mode, the two variables (count1 and count2) are not used and can be initialized.

If it is determined in step S720 that the measured distance L is smaller than the first distance L1, the process proceeds to step S730 in which the measured distance L is equal to the first distance L1 and the second distance L2. It may be determined whether or not there is a distance between them, that is, whether the measured distance L is in the limited section.

If it is determined in step S730 that the measured distance L is within the limited period, the process proceeds to step S731 where count1 is added by one and count2 may be initialized to zero. Next, if count1 is smaller than the first time T1 in step S733, the process proceeds to step S770 (that is, since a predetermined time has not passed, the eye protection mode is not entered), and in step S733, count1 is the first time (T1). If it is equal to or greater than), the display may enter the steps S735 and S737 and adjust the display angle P to be the eye protection angle P1. When the steps S735 and S737 are described separately, step S735 confirms that the current display angle P is substantially the same as the eye protection angle P1, and if so, proceeds directly to step S770 without adjusting the display angle. If different, the process proceeds to step S737 to adjust the display angle to the eye protection angle and illustrates the procedure to proceed to step S770.

If it is determined in step S730 that the measured distance L is not within the limited section (that is, the measured distance L is smaller than the second distance L2), the flow proceeds to step S751 to determine the current display angle ( It is possible to confirm whether P) is substantially the same as the viewing angle P0. If it is determined in step S751 that the current display angle P is different from the viewing angle P0, the process may proceed to step S752 to adjust the display angle P to the viewing angle P0 and then proceed to step S770.

If it is determined in step S751 that the current display angle P is substantially the same as the viewing angle P0, the flow proceeds to step S753 to initialize count1 to zero and add count2 by one. Thereafter, the process proceeds to step S755 and count2 is compared with the second time T2. If count2 is less than the second time T2, the process proceeds to step S770 immediately (without a separate warning message or mode switching), and count2 If it is greater than or equal to the second time T2, the process may proceed to step S757 to display a warning message. The warning message in step S757 may be used to warn in advance that the user may be switched to the vision protection mode if the elapsed time in the operation mode continues. Next, in step S759, after count2 is compared with the third time T3 that is greater than the second time, if count2 is less than the third time T3, the process proceeds directly to step S770 (without changing the mode), and count2 is If it is greater than or equal to the third time T3, the display angle may be changed to the vision protection angle by proceeding to step S735 (that is, forced switching from the operation mode to the vision protection mode). As described above, steps S753 to S759 illustrate a procedure of first displaying a warning message when the elapsed time in the operation mode becomes long and then forcibly switching to the vision protection mode if the operation mode continues.

Step S770 is a step of determining whether to continue the angle adjustment function after the operation according to the distance measurement and mode division once, proceed to step S710 to resume the distance measurement if the angle adjustment function continues, otherwise the angle The termination of the adjustment procedure is illustrated.

As described above, according to an exemplary embodiment of the present invention, when the user approaches the display, the display angle may be changed to prevent the user from watching the display for a long time while the user approaches the display. In addition, according to the exemplary embodiment, the eyesight protection function may be easily implemented using the display mounting apparatus without modifying the hardware or software of the electronic device including the display. In addition, according to an exemplary embodiment, the user may distinguish the case where the user is close to the display to operate the electronic device to apply an eye protection function so as not to cause inconvenience to the user's operation. In addition, according to the exemplary embodiment, the user may effectively respond to the case where the user wants to disable the vision protection mode to perform the vision protection function.
