For example, when the state measured in step S200 is the internal temperature, the control unit 110 sets the transparency to 50% when the measured internal temperature exceeds the reference value, and the transparency is 100 when the measured internal temperature is less than the reference value. You can also decide to be %. In this case, if the measured internal temperature exceeds the reference value, the notification window is displayed in a state that the user can recognize (transparency 50%), but if the measured internal temperature is less than the reference value, the user cannot recognize it. As a result, the notification window may be displayed (transparency of 100%).

In addition, in step S202, the control unit 110 may, of course, determine the transparency of the notification window based on a degree that the measured state deviates from a reference value or a time deviates from the reference value. That is, for example, when the state of the image display device 100 measured in step S200 is an internal temperature, when the measured internal temperature exceeds a preset reference value by 5 degrees or more and 10 degrees or more, Different transparency can be determined (transparency 30% when exceeding 5 degrees, transparency 50% when exceeding 10 degrees). Alternatively, the control unit 110 determines different transparency levels when the measured internal temperature exceeds the reference value for 10 minutes or more and 20 minutes or more (transparency 30% for 10 minutes or more, and 50% transparency for 20 minutes or more). You may.

That is, the control unit 110 determines the importance or severity of information to be informed to the user (notification information) based on the measured state and the related reference value, and makes the transparency different based on the determined importance or severity. If less important or less severe, the transparency of the notification window may be set high, and if more serious or more important, the transparency of the notification window may be set lower so that the user can quickly check the notification information included in the notification window. In addition, since the transparency of the notification window is determined based on the importance or severity of the included notification information, the user can intuitively recognize the importance or severity of the notification information based on the transparency level of the notification window.

Meanwhile, the severity of the notification information may be related to a state related to the performance or function of the video display device. For example, when the internal temperature or the cooling fan rotation speed of the image display device 100 greatly exceeds a preset reference value or the exceeded state persists for a long time, the controller 110 may be related to the internal temperature or the cooling fan rotation speed. It can be determined that the notification information has a high severity level. And, in the case of notification information having a high severity level, the transparency may be set to be low.

In addition, the importance of the notification information may be arbitrarily set by the user. For example, when the user reserves the viewing of a specific content or sets a specific alarm, the controller 110 may further receive an importance level when the viewing reservation or the alarm is set. In addition, in determining the transparency of the notification window by comparing the measurement result of the current time with the time set in the viewing reservation or alarm, in the case of the viewing reservation or alarm set with a higher importance, the lower transparency is You can also let it be decided.

Meanwhile, in the above description, it has been described that only the transparency of the notification window is determined based on the measured state and a related reference value, but not only the transparency but also the size of the notification window may be changed. Hereinafter, a case where the size as well as the transparency of the notification window is changed will be described in more detail with reference to FIGS. 4 and 8 below.

As described above, in step S202, it has been described that the importance or severity of the notification information is determined according to the result of considering the measured state and the related reference value, but the reference value is within a certain range having an arbitrary minimum value and a maximum value as described above. May be. In this case, the control unit 110 may determine whether the state measured in step S200 is out of a certain range set as a reference value, and determine the transparency based on the determination result.

For example, when the result of measuring the state of the image display device 100 in the step S200 is out of a certain range and does not deviate from a certain range, the control unit 110 determines different transparency (for example, when out of a certain range, the transparency 50%, or 100% transparency if it does not deviate). Alternatively, the control unit 110 may allow the transparency of the notification window to be determined based on the degree to which the state measurement result is out of the predetermined range. It goes without saying that the control unit 110 may change the size as well as the transparency of the notification window based on whether the measured state is out of the predetermined range or the extent out of the predetermined range.

In addition, it goes without saying that the transparency of the notification window determined in step S202 may have a preset maximum or minimum value. In this case, when the transparency of the notification window determined in step S202 is out of the preset maximum or minimum value, the transparency of the notification window may be determined by the maximum or minimum value.

Meanwhile, when the transparency of the notification window is determined in step S202, the control unit 110 displays the notification window by overlapping at least a portion of the area where image information is displayed on the display unit 120 (S204). Further, the control unit 110 determines the degree to which image information of the area in which the notification window is displayed is displayed through the notification window based on the transparency determined in step S202. Accordingly, in the area in which the notification window is displayed, image information of the area in which the notification window is displayed may be displayed on the notification window based on the transparency determined in step S202. Accordingly, as long as the transparency determined in step S202 is not 0%, both image information and notification information may be displayed in the notification window.

Meanwhile, the control unit 110 may repeat the process from step S200 to step S204 at a predetermined time cycle. To this end, when the notification window is displayed on the display unit 120 in step S204, the controller 110 determines whether a preset period has expired (S206). In addition, if a predetermined period has expired as a result of the determination in step S206, the process proceeds to step S200 to repeat the process from step S200 to step S204.

Meanwhile, in the above description of FIG. 2, it has been described that only the transparency of the notification window displayed on the display unit 120 is determined based on the measured state and a related reference value. However, based on the measured state and a reference value, the Of course, you can also decide whether to display the notification window. For example, based on the measured state and the reference value, the control unit 110 has a certain level of importance or severity of the information to be informed to the user, or when the current state of the image display device 100 is normal or there is no information to be informed to the user. Of course, the notification window may not be displayed if it is below the level.

3 illustrates a flow of an operation process of an image display device according to an embodiment of the present invention in this case.

Referring to FIG. 3, when the state of the image display device 100 is measured in step S200, the controller 110 may determine whether to display a notification window based on the measured state and a reference value related to the measured state. .

In the step S300, the controller 110 may determine whether information to be notified to the user, that is, notification information, has occurred based on the state measured in the step S200 and a reference value associated therewith. For example, when the measured state does not exceed a reference value, the controller 110 may determine that there is no information to be notified to the user. Alternatively, when the measured state is the current time measured by the video display device 100 and the reference value is a time set by a specific viewing reservation or alarm, the time currently measured by the video display device 100 is the viewing reservation or When the time is more than a certain time ahead of the time set by the alarm, it may be determined that there is no information to be informed to the user. In this case, instead of determining the transparency of the notification window as 100% in FIG. 2, the controller 110 may prevent the notification window from being displayed in the step S300.

In contrast, when the measured state deviates from the reference value (including the case where the current measured time and the time set by the viewing reservation or alarm are within a certain time), the controller 110 indicates that there is information to be informed to the user. I can judge. If it is determined that there is notification information as described above, the controller 110 may determine to display a notification window in step S300. In addition, the control unit 110 determines notification information to be displayed in the notification window in consideration of both the measured state and the reference value.

For example, if the measured state is an internal temperature, the controller 110 may include, as the notification information, a currently set reference value and a currently measured temperature in the notification information. And if the measured state is the current time, the control unit 110 may include, as the notification information, a time set for a specific viewing reservation or alarm and the remaining time from the current time to the time set for the measurement viewing reservation or alarm. I can.

Meanwhile, as a result of the determination in step S300, if the notification window is displayed, the control unit 110 proceeds to step S202 to determine the transparency of the notification window (S302), and if the notification window is not displayed, the currently displayed notification window is Whether or not it can be determined (S304). As a result of the determination in step S304, if there is a currently displayed notification window, the control unit 110 ends the display of the currently displayed notification window (S306). This is because it is no longer necessary to display the notification window based on the determination result of step S300. Then, the controller 110 proceeds to step S206 and determines whether or not a preset period has expired. In addition, if there is no notification window currently displayed as a result of the determination in step S304, the process proceeds directly to step S206 to determine whether a preset period has expired. In addition, the control unit 110 may repeat a process from step S200 including steps S300 to S306 to step S204 according to the preset period.

Meanwhile, when it is determined whether to display the notification window as shown in FIG. 3, when the transparency is 100% as described above, the notification window may not be displayed. In addition, if there is notification information in step S300, that is, when a notification window is displayed, the controller 110 may have a maximum value of the transparency of the notification window having a value of less than 100%. That is, when the notification window is displayed, the controller 110 allows the notification window to be displayed only below a preset maximum value (a value less than 100%), so that the transparency of the notification window becomes 100% when there is notification information. It can be prevented from being determined.

Meanwhile, in the above description, it has been mentioned that the size and transparency of the notification window may be determined by further considering the importance or severity of the notification information.

4 shows a flow of an operation process in which not only the size and transparency of the notification window but also the frequency of displaying the notification window is adjusted based on the importance or severity of the notification information.

Referring to FIG. 4, when the transparency of the notification window is determined in step S204, the control unit 110 of the image display device 100 according to an embodiment of the present invention may determine notification information to be displayed on the notification window (S400). )

Here, the notification information may be information to be notified to the user as described above. For example, the notification information may be information related to the state measured in step S200. In addition, the notification information may be information obtained by comparing the current time and the viewing reservation information or the time set in the alarm, or may be information generated in the video display device (for example, software update information).

Further, the controller 110 may determine the importance or severity of the notification information based on at least one of a type of notification information to be displayed in the notification window and a result of comparing the measured state with the reference value (S402).

For example, in step S402, the controller 110 may determine the severity level of the notification information based on a result of comparing the reference value related to the state measured in step S200. That is, as a result of the comparison, when the measured state deviates from the reference value by a predetermined level or more, the controller 110 may determine that the severity level of notification information for notifying that the measured state deviates from the reference value is high. Conversely, when the measured state deviates from the reference value less than a certain level, the controller 110 may determine that the severity level of the notification information for notifying this is low.

It goes without saying that the control unit 110 may also determine the severity level for notifying the state based on the duration of the state beyond the reference value. In addition, the control unit 110 may determine the severity level based on the degree of state change over a certain period of time. Here, the controller 110 may determine the severity level based on the state change degree only when the reference value is exceeded. That is, the controller 110 may determine the severity level based on a change amount of the difference between the reference value and the measured state for a predetermined time.

In addition, the controller 110 may determine the severity level of the notification information based on the type of the notification information. For example, the controller 110 may determine that the severity level is high when information related to a state that directly affects the performance or safety of the image display device 100, such as an internal temperature or a temperature of a CPU. However, if the state does not directly affect the performance or safety of the image display device 100, such as luminance or volume, or the amount of dust introduced into the interior, it may be determined that the severity level is low. However, even when the state does not directly affect the performance or safety of the image display device 100 as described above, if the measured state exceeds the reference value by a certain level or more, or if the abnormal state continues for a certain time or longer, the control unit ( 110) can determine that these conditions also have a high severity level.

Meanwhile, the controller 110 may also determine the level of importance of the notification information. And, as described above, the importance may be set arbitrarily by the user. For example, when a user reserves the viewing of a specific content or sets an alarm at a specific time, the user may additionally set the importance of the viewing reservation or alarm. In addition, a viewing reservation or alarm set with a higher importance may have a lower transparency than other viewing reservation or alarm settings.

Meanwhile, in the above description, it has been described that the importance level is set in the case of a viewing reservation or alarm setting of a specific content, but the importance level may be set in addition to the viewing reservation or alarm setting. For example, the user may set an importance level for a specific state of the image display device, and in this case, notification information for a specific state in which the importance level is set may be displayed through a notification window having a lower transparency. That is, for example, when the user has set the importance of the internal temperature of the image display apparatus 100, the control unit 110 may change the transparency determined in step S202 by reflecting the importance.

On the other hand, in the above description, only the case where the transparency of the notification window is lowered due to the importance level has been described. Conversely, the transparency of the notification window may increase. This is because the user may set the importance of a specific state of the video display device 100 or a specific viewing reservation or alarm to a lower level than usual. In this case, a higher transparency than the transparency determined in step S202 may be determined by reflecting the low level of importance.

On the other hand, if the importance or severity level of the notification information is determined in step S402, the controller 110 may change at least one of the size and transparency of the notification window determined in step S202 based on the determined importance or severity level. Yes (S404). Accordingly, the size of the notification window displayed on the image display device 100 according to the exemplary embodiment of the present invention may be changed based on the importance or severity level, and the transparency may also be changed. An example in which the size and transparency of the notification window are changed will be described in more detail with reference to FIG. 8 below.

In addition, the controller 110 may change a preset period based on the importance or severity level determined in step S402 (S404). Here, the'preset period' may mean a predetermined time interval for determining the transparency and size of the notification window by measuring the state of the image display device 100. That is, the'preset cycle' may mean a'preset cycle' of step S206 in which the process from step S200 to step S204 is repeated.

In this case, the process from step S200 to step S204 may be repeated at shorter time intervals or at longer time intervals based on the importance or severity level determined in step S402. Accordingly, the controller 110 can measure the state of the video display device 100 faster than when the importance or severity level of the notification information determined in step S402 is high, and on the contrary, the importance or severity level of the notification information is If it is low, the state of the image display device can be measured more slowly. Accordingly, the transparency of the notification window may be changed more quickly or more slowly, or the frequency of displaying the notification window may be faster or slower.

Meanwhile, if at least one of the size and transparency of the notification window, and a preset period is changed in step S404 based on the importance or severity level of the notification information, the controller 110 proceeds to step S206 again and the preset period is changed. It is determined whether or not it has expired, and the process from step S200 to step S204 may be repeated based on the determination result of step S206.

Meanwhile, when the state of the image display device 100 temporarily deviates from the reference value and is restored to its original state, the control unit 110 of the image display device 100 according to an exemplary embodiment of the present invention has the transparency of the notification window. An arbitrary transparency change rate control variable may be used to prevent rapid change. Here, the transparency rate control variable may be determined by a user. Equation 5 below shows that the transparency is changed based on the transparency rate control variable.

[Equation 5]

Here, the preset time may be a time corresponding to at least one period. For example, the control unit 110 determines a constant corresponding to the transparency (%) of the currently determined notification window, and from the determined constant, a constant corresponding to the difference between the currently measured state and the reference value is set to a limit value, and the transparency rate An adjustment variable (constant) may be added to determine the transparency of the notification window.

For example, when the currently determined notification window has 100% transparency, the controller 110 may determine '100' as a constant corresponding thereto. In addition, a difference between the constant '100' and a constant corresponding to the difference between the currently measured state and the reference value may be obtained. If the measured state is the internal temperature of the image display device 100, the current measured state is 65 degrees, and the reference value related to the internal temperature is 55 degrees, the difference between the currently measured state and the reference value The constant corresponding to can be 65-55 = 10.

In this state, the controller 110 obtains a limit value of '90' for a constant '10' corresponding to the difference between the currently measured state and the reference value from the constant '100' corresponding to the transparency of the current notification window, and the obtained constant The transparency corresponding to '90', that is, 90% may be set. However, in contrast, when the transparency rate control variable is further used, the degree to which the transparency of the notification window is changed may be smaller.

For example, when the temperature inside the image display device measured in the previous cycle is 55 degrees, and the'preset time' in Equation 5 is a time corresponding to one cycle, the controller 110 As the amount of state change, 10 degrees, the difference between 65 degrees (currently measured temperature) and 55 degrees (measured temperature in the previous cycle), can be obtained. In addition, '10' may be determined as a constant corresponding to the state change '10 degrees' during the preset time. In addition, if the transparency rate control variable arbitrarily set by the user is '5', the transparency of the notification window may be '96' (100-(10+10)/5) by Equation 5 above. In addition, the controller 110 may determine the transparency of the notification window to correspond to the obtained value '96'. For example, the transparency of the notification window corresponding to the constant '96' may be '96%'.

Therefore, the transparency of the notification window may vary based on whether the transparency rate adjustment variable is reflected. In addition, even if the state measured by the measurement unit 130 changes temporarily and abruptly based on this difference, the transparency of the notification window may be gradually changed in size. In addition, as described in Equation 5, the larger the transparency rate control variable, the smaller the amount of transparency may be, and the smaller the transparency rate control variable, the larger the amount of transparency may decrease.

Meanwhile, the above-described example assumes that the measured state is the internal temperature of the image display device. Accordingly, a constant corresponding to a temperature change of 10 degrees is determined as 10, and transparency of the notification window is determined based on Equation (5). Therefore, if the measured state is a state other than temperature, constants corresponding to the measured state or a reference value related to the measured state may be determined based on a preset weight. For example, in the case of the fan speed, if 3000rpm is a measured value or a reference value, the constant corresponding to 3000rpm may be 60 (for example, when the weight corresponding to the fan speed is 1/50). These weights may be determined by experimentation or the like, and may be stored in the storage unit 140.

Meanwhile, when transparency is determined based on Equation (5), when transparency is decreased or increased, it may be gradually changed based on the transparency rate control variable. However, in this case, even when the currently measured state does not exceed a preset reference value, that is, when the state of the image display device 100 rapidly recovers to a normal state, the transparency of the notification window gradually increases.

In order to prevent such a case, in the image display device 100 according to an embodiment of the present invention, when the transparency decreases or the transparency increases, the transparency of the notification window may be determined in different ways. This is to allow the transparency of the notification window to be determined by reflecting it when the state of the image display device 100 continuously deviates from the reference value for a certain level or more or for a certain period of time or more.

5 illustrates an operation process of determining the transparency of the notification window in different ways when the transparency of the notification window is increased or decreased.

Referring to FIG. 5, when the transparency of the notification window is determined in step S202, the control unit 110 determines whether the transparency of the notification window will increase or decrease by comparing the state measured in step S200 with a corresponding reference value. do. For example, the control unit 110 may increase the amount of change in the difference between the state measured in step S200 and the reference value for a certain period of time, or the measured state does not deviate from the reference value and then goes out of the reference value. If changed, it may be determined that the transparency of the notification window will increase. On the contrary, when the amount of change in the difference between the measured state and the reference value decreases, or when the measured state is out of the reference value and changes to a state that does not exceed the reference value, the transparency of the notification window is It can be determined that it will decrease.

In this case, the controller 110 may determine the transparency of the notification window in different ways based on the determination result of step S500. For example, when it is determined that the transparency of the notification window is reduced as a result of the determination in step S500, the controller 110 may determine the transparency of the reduced notification window based on Equation (5). However, when it is determined that the transparency of the notification window is increased as a result of the determination in step S500, the increased transparency of the notification window may be determined based on Equation 6 below.

[Equation 6]

When the current measured state of the image display device 100 is'internal temperature', the controller 110 is based on the difference between the current measured value and the threshold value and the amount of temperature change during a preset time based on Equation 6 above. Thus, the increased transparency of the notification window may be determined.

For example, when the currently set notification window has a transparency of 50%, the controller 110 may determine '50' as a constant corresponding to the transparency of 50%. And when the preset time is a time corresponding to one cycle, the temperature measured in the previous cycle is 61 degrees, the current measured temperature is 60 degrees, and the reference value corresponding to the'internal temperature' is 50 degrees, the controller ( 110) determines a constant '1' corresponding to 1 degree (61-60) as the amount of change during a preset time and a constant '10' corresponding to 10 degrees (60-50), which is the difference between the measured value and the reference value. I can.

Accordingly, the control unit 110 calculates a constant '55' (50+[(100-50)x1/10]) based on Equation 6 when the temperature exceeding the reference value decreases as shown in the above example. can do. In addition, the transparency of the notification window may be determined as '55%' corresponding to the constant '55' calculated based on Equation 6 above.

In the above example, it is also assumed that the measured state is the internal temperature of the image display device. Accordingly, a constant corresponding to 1 degree of temperature change is determined as 1, and a constant corresponding to 10 degrees, which is the difference between the measured value and the reference value, is determined as 10. Therefore, if the measured state is a state other than temperature, the constants corresponding to the measured state or a reference value related to the measured state may be determined based on a preset weight as described above.

6 illustrates an example in which the transparency of a notification window is changed in the image display device according to an embodiment of the present invention.

First, referring to FIG. 6A, FIG. 6A assumes that the notification window is not displayed or the transparency of the notification window is 100%. For example, even if the notification window is displayed, when the transparency is 100%, the notification window may be displayed in a form that the user does not recognize as shown in FIG. 6A.

As shown in (a) of FIG. 6, when the notification window is not displayed or the transparency of the notification window is 100%, there is no information to be notified to the user or the state of the image display device 100 is in a normal state, that is, a reference value. It is the case that it is not out of In this state, when notification information occurs or the measured state of the image display device 100 exceeds a preset reference value, the control unit 110 may display a notification window or change the transparency of the notification window.

In the following description, for convenience of explanation, it is assumed that the state measured by the image display device 100 is'internal temperature'. However, it goes without saying that the present invention is not limited to the case where the'internal temperature' is measured.

The controller 110 of the image display device 100 according to an exemplary embodiment of the present invention, in the state as shown in FIG. 6A, when the preset period of time expires, the internal temperature of the image display device 100 Can be measured. Also, based on the measured internal temperature, a notification window may be displayed or the transparency of the notification window having a transparency of 100% may be changed.

For example, when the currently measured internal temperature of the image display device 100 is '55 degrees', the controller 110 may compare the measured internal temperature '55 degrees' with a preset reference value '53 degrees'. In addition, when the current measured internal temperature exceeds a preset reference value as a result of the comparison, the controller 110 may determine that there is information to notify the user. Then, the controller 110 determines the content of the notification information to be displayed on the notification window and displays the notification window (S300), or determines that the transparency of the notification window (transparency 100%) containing information related to the current internal temperature is reduced (S202). )can do.

6B shows this example.

As shown in (b) of FIG. 6, the notification window 600 may include various notification information related to the internal temperature. For example, the notification information may include currently measured temperature information 602, reference internal temperature information, and a guide 604 for the current temperature.

Here, the guide 604 displayed on the notification window 600 may be a description of the state of the currently measured image display device 100, or the user may It may contain information on instructions to be taken, etc. Accordingly, the guide 604 may include different contents based on the currently measured state.

In addition, the transparency of the notification window 600 may be determined according to a difference between the currently measured internal temperature and the reference internal temperature. Accordingly, when the difference between the currently measured internal temperature and the reference internal temperature is not large, as shown in FIG. 6B, the transparency is set high, and image information displayed on the display unit 120 through the notification window is It can be seen more clearly than the notification window. Accordingly, the user may not be disturbed by the notification window to view the image information displayed on the display unit 120, and can intuitively recognize that the current situation is not very serious based on the transparency of the notification window. .

Meanwhile, when the preset period expires, the controller 110 may measure the internal temperature of the image display device 100 again. In addition, the transparency of the notification window may be determined based on the measured internal temperature and a preset reference internal temperature. In this case, if the amount of the currently measured internal temperature deviated from the reference internal temperature is less than the amount measured in the last cycle, the control unit 110 determines the transparency of the notification window to be higher or stops displaying the notification window. You may. In this case, it is possible to return to the state of Figure 6 (a).

However, if the amount of the currently measured internal temperature deviated from the reference internal temperature is greater than the amount measured in the last cycle, the controller 110 changes the content of the notification information displayed in the notification window and the You can also decide to reduce the transparency of the notification window.

Figure 6 (c) shows such an example.

For example, as shown in (c) of FIG. 6, when the temperature measured in the current cycle is 60 degrees, the control unit 110 deviates from the reference internal temperature (5 degrees), and the amount deviates from the reference internal temperature in the last cycle. It can detect something larger than (2 degrees). In this case, the controller 110 includes a guide 604 for notifying that the internal temperature of the image display device 100 deviates from the reference internal temperature by a greater degree, as shown in FIG. 6C, and the currently measured internal temperature. Notification information including 602 may be displayed on the notification window 600. In addition, the controller 110 may determine the transparency of the notification window 600 by reflecting the degree to which the internal temperature of the image display apparatus 100 deviates from the reference internal temperature. Accordingly, as shown in (c) of FIG. 6, the transparency of the notification window 600 may be determined to be a further reduced value, and accordingly, the notification information displayed on the notification window is an image displayed on the display unit 120. It can be seen more clearly than information. Accordingly, the user can intuitively recognize that the internal temperature of the image display device 100 is higher based on the transparency of the notification window.

Meanwhile, when the notification window 600 is displayed as shown in (c) of FIG. 6, the controller 110 may measure the internal temperature of the image display device 100 again when the preset period expires. Further, the transparency of the notification window 600 may be determined based on the measured internal temperature and the reference internal temperature. Accordingly, when the currently measured internal temperature is lowered, the controller 110 may return to the state shown in FIG. 6(b) or 6(a).

However, if the internal temperature of the currently measured image display device 100 is higher, the controller 110 may determine the transparency of the notification window as a further reduced value. For example, when the current measured internal temperature of the image display device 100 exceeds the reference internal temperature for a predetermined time or longer, or the measured internal temperature exceeds the reference internal temperature by a certain level or more In this case, the transparency may be determined as 0%. Here, the control unit 110 may determine the transparency of the notification window 600 based on the type of the notification information or the importance or severity of the notification information, and determine the transparency of the notification window 600 as 0%. Of course.

In addition, when the transparency of the notification window 600 is determined to be 0%, the controller 110 may be in a completely opaque state, as shown in FIG. 6D. This is because it is more urgent to inform the user about the currently measured state than to disturb the user's viewing of the content screen. In addition, when the notification window is displayed as shown in (d) of FIG. 6, the user can intuitively determine that the state of the image display device 100 is a serious state or a very important state.

Meanwhile, in the case of FIG. 6, an example in which a notification window is displayed is described assuming that the internal temperature of the current image display device 100 is measured. However, unlike this, the notification window is based on a viewing reservation or an alarm set by the user. Of course, it can also be displayed. In this case, the measurement unit 130 measures time information of the current video display device 100, compares the time set in the viewing reservation or alarm with the measured time, and displays a notification window displaying related information. You can do it.

7 shows an example of a notification window displayed by notification information in this case.

For example, if there is no viewing reservation or alarm set by the user, the controller 110 has no information to notify the user, and thus may be displayed as shown in FIG. 7A. Or even if there is a preset viewing reservation or alarm, as a result of comparing the time measured by the current video display device 100 with the time set in the viewing reservation or alarm, the remaining time is the preset time (first time). If it is exceeded, the notification window may not be displayed as shown in FIG. 7A or the notification window having 100% transparency may be displayed.

However, if, as a result of comparing the currently measured time with the time set in the preset viewing reservation or alarm, the remaining time is less than the preset time (first time), the controller 110 displays a notification window based on the remaining time. Or, you can change the transparency of the notification window.

Figure 7 (b) shows such an example.

Referring to (b) of FIG. 7, the control unit 110, as shown in (b) of FIG. 7, is the time from the currently measured time to the time set in the preset viewing reservation or alarm, that is, the remaining time. When it is less than a predetermined time (first time), a notification window 700 including related notification information may be displayed. Here, the notification information may include information on the current remaining time.

Alternatively, when the notification window (transparency 100%) is already being displayed, the controller 110 may determine to decrease the transparency of the notification window 700 based on the remaining time. For example, when the transparency determined when the remaining time is '1 hour' is 85%, as shown in FIG. 7(b), the display 120 is more than the notification information displayed on the notification window 700. The image information displayed on can be seen more clearly.

However, when a certain time elapses and the remaining time is measured to be less than a preset certain time (second time), the controller 110 may change the transparency of the notification window based on this. For example, as shown in (c) of FIG. 7, when the remaining time is reduced to '30 minutes', the controller 110 may set the transparency of the notification window 700 to be lower based on this. Accordingly, as shown in (c) of FIG. 7, the notification information displayed on the notification window 700 may be more clearly viewed than the image information displayed on the display unit 120.

In addition, when time elapses further and the remaining time decreases within a predetermined time (third time), the control unit 110 may set the transparency of the notification window 700 to be lower to reflect this. For example, the control unit 110 may set the transparency of the notification window 700 to '0%', and in this case, the control unit 110 may use the notification window 700 as shown in FIG. 7(d). Image information on the display unit 120 may not be displayed. This is to inform the user that the currently set viewing reservation time or alarm time is imminent.

Meanwhile, in the description of FIG. 7, a case where the currently measured time is earlier than the time set for the viewing reservation or alarm, that is, the case where the remaining time is measured, is described as an example, but unlike this, the currently measured time is the viewing reservation or alarm It goes without saying that the present invention can be applied even when the time set in is elapsed. This may occur, for example, when the user selects to continue viewing the currently viewed content screen, even if a viewing reservation is set. In this case, the control unit 110 may include information about a time that has passed the time set for the viewing reservation or alarm as'Passed Time' instead of'Left Time' in the notification information. . In addition, as the elapsed time increases, the control unit 110 may increase the transparency of the notification window for displaying the elapsed time. Accordingly, the notification window 700 may be displayed in a state similar to the state shown in (c) and (b) of FIG. 7. And when the elapsed time is more than a certain time (the fourth time), the controller 110 stops displaying the notification window 700 or changes the transparency of the notification window 700 as shown in FIG. 7A. You can also decide to 100%.

On the other hand, in the above description of FIGS. 6 and 7, only the transparency of the notification window is changed. However, unlike this, the size of the notification window may also be changed as mentioned in the description of FIG. 4. .

FIG. 8 shows an example in which the size and transparency of a notification window are changed in the image display device according to an embodiment of the present invention.

For example, when the currently measured state of the image display device 100 is not very serious, or the importance or severity level of the notification information is less than a certain level, the controller 110 may, as shown in FIG. 8A, The notification window 800 set with a high transparency may be displayed on the display 120 so that image information displayed on the display 120 can be clearly seen than the notification information displayed on the notification window 800. In addition, in this case, the controller 110 may display the notification window 800 in the same size as shown in FIG. 8A.

However, if, for example, the state of the currently measured image display device 100 exceeds a preset reference value, or the state exceeding the preset reference value continues for a certain time or longer, the severity level of the notification information is reduced. When it increases, the controller 110 may determine the transparency of the notification window 800 to be lower as shown in FIG. 8B. In addition, the controller 110 may determine the size of the notification window 800 to be larger than the size indicated in FIG. 8A. In this case, the sizes of the notification information 802 and 804 displayed on the notification window 800 may also be displayed larger. This is to allow the user to intuitively know that the state of the currently measured image display device 100 is worse or that the severity level of the notification information is higher.

On the other hand, compared to the case shown in (b) of FIG. 8, when the state of the video display device 100 is worse (if it exceeds the reference value) or the severity level of the notification information is higher, the controller 110 As shown in (c) of FIG. 8, the transparency of the notification window 800 may be determined as 0%. Further, based on this, the size of the notification window 800 and the notification information 802 and 804 displayed on the notification window 800 may be increased. Therefore, in the image display device 100 according to an embodiment of the present invention, the user can more intuitively change the current state of the image display device 100 according to a change in the size of the notification window 800 as well as the transparency of the notification window 800. To be aware of

Meanwhile, in the description of FIG. 8, it is assumed that the transparency of the notification window 800 decreases and the size of the notification window 800 increases based on a deterioration in the state of the image display device 100 or an increase in the severity level of the notification information. I did. However, in the opposite case, that is, when the state of the image display device 100 improves (the amount of the measured state exceeds the reference value decreases) or the severity level of the notification information decreases, the controller 110 is based on this. As a matter of course, the transparency of the notification window 800 may be increased and the size of the notification window 800 may be reduced. In addition, in the above-described example, it is assumed that both the transparency and the size of the notification window 800 are changed. However, unlike this, only one of the transparency and the size of the notification window 800 may be changed.

It goes without saying that the controller 110 may change the preset period based on a change in the state of the image display device 100 or a change in the severity level of the notification information. In this case, when the state of the image display apparatus 100 deteriorates or the severity level of the notification information increases, the control unit 110 may change the preset period to be shorter. In this case, when the preset period is shortened, the controller 110 measures the state of the image display device 100 at a shorter period of time, so that at least one of the transparency and size of the notification window 800 may be changed more quickly. You may.

However, if the state of the image display device 100 improves or the severity level of the notification information decreases, the controller 110 may change the preset period to be longer. In this case, when the preset period is longer, the controller 110 measures the state of the image display device 100 at a longer period, so that at least one of the transparency and size of the notification window 800 may be changed more slowly. You may. Accordingly, as the preset period is changed, a frequency at which at least one of the transparency and size of the notification window 800 is changed may be changed.

Meanwhile, it goes without saying that the notification window may be viewed only through 3D polarized glasses using a film patterned retarder (FPR) method. For example, a ticker bar composed of a film patterned retarder (FPR) film is formed on the display unit 120 of the image display device 100 according to an embodiment of the present invention, and the ticker Notification information may be displayed only through the bar.

9 illustrates an image display device according to an exemplary embodiment of the present invention when a notification window is displayed using a polarizing film pattern format as described above.

For example, as shown in (a) of FIG. 9, the ticker bar 900 may be formed below the display unit 120. In this case, the controller 110 may display different notification information on the ticker bar using a polarization method.

For example, the control unit 110 causes the notification information to be displayed on the ticker bar 900 in the same polarized light as the polarized light used in the preset 3D polarization glasses 910, and the image on the display unit 120 in a different polarization method. Information can also be displayed. In this case, as shown in (b) of FIG. 9, the user wearing the 3D polarized glasses 910 can check the notification information 920 displayed on the ticker bar 900, but the 3D polarized glasses ( A user who does not wear the 910 can check only image information displayed on the display unit 120. Accordingly, the image display device 100 according to an embodiment of the present invention may allow the notification information to be displayed only to a person who needs to check the notification information, such as a device manager or a monitor.

In addition, the ticker bar 910 can be used for various purposes. For example, when the image display device 100 according to an embodiment of the present invention is a digital signage device, advertisement information may be displayed on the ticker bar 910. That is, the control unit 110 causes the notification information to be displayed on the ticker bar 900 in the same polarized light as the polarized light used in the 3D polarization glasses 910 set in the ticker bar 910, and uses a different polarization method. As shown in (c) of 9, the advertisement information 930 may be displayed. In this case, the user wearing the 3D polarized glasses 910 can check the notification information 920 displayed on the ticker bar 900, but the user who does not wear the 3D polarized glasses 910 may check the advertisement information 930 ) Can only be checked.

The above-described present invention can be implemented as a computer-readable code on a medium on which a program is recorded. The computer-readable medium includes all types of recording devices that store data that can be read by a computer system. Examples of computer-readable media include HDD (Hard Disk Drive), SSD (Solid State Disk), SDD (Silicon Disk Drive), ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage device, etc. There is also a carrier wave (e.g., transmission over the Internet). Also, the computer may include the controller 180 of the terminal. Therefore, the detailed description above should not be construed as restrictive in all respects and should be considered as illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the equivalent scope of the present invention are included in the scope of the present invention.
