10 and 11 are diagrams to explain charging current control according to the setting mode of the display device 100 according to an embodiment of the present disclosure.

FIG. 12 is a flowchart illustrating charging current control according to the setting mode of the display device 100 according to an embodiment of the present disclosure.

8 and 9 describe the operation of the display device 100, that is, the processor 620 within the processing unit, for charging the battery 630 based on the power supplied from the adapter 640.

First, referring to FIG. 8, the processor 620 may create an adapter characteristic profile (S101).

The processor 620 may set the output voltage operating range of the adapter 640 based on the adapter characteristic profile (S103).

The processor 620 may detect the voltage and current levels of the adapter 640 and calculate the power consumption of the display device 100 (S105).

The processor 620 may determine whether the power consumption calculated in step S105 is less than the rated output of the adapter 640 (S107).

If, as a result of the determination in step S107, the power consumption calculated in step S105 is less than the rated output of the adapter 640, the processor 620 may perform a first control operation on the current level for charging the battery 630 ( S109).

Here, the first control operation may be an operation to control the current level for charging the battery 630 to gradually increase. At this time, controlling to gradually increase may refer to a control operation that increases the current level linearly or in a step-up manner (see (b) of FIG. 10). However, it is not limited to this, and in this specification, the gradual increase refers to any form (nonlinear) in which the current level increases according to the voltage level (for example, within the operating range of the output voltage of the adapter 640 set in step S103). It may also be included.

Next, referring to FIG. 9, the processor 620 may first monitor the output voltage level of the adapter 640 (S201).

The processor 620 may determine whether the output voltage level of the first monitored adapter 640 exceeds the operating range of the adapter output voltage preset in step S103 of FIG. 8 (S203).

As a result of the determination, the processor 620, if the output voltage level of the first monitored adapter 640 exceeds the operating range of the adapter output voltage set in step S103 of FIG. 8, the first controlled battery 630 ) A second control operation may be performed on the current level for charging (S205). Here, the second control operation, unlike the first control operation described above, may be an operation that controls the current level for charging the battery 630 to decrease. Depending on the embodiment, the increasing slope and decreasing slope in the first control operation and the second control operation may or may not be symmetrical to each other (or the same depending on the viewpoint). For example, the slope of the current level gradually decreased according to the second control operation may be smaller than the slope of the current level gradually increased according to the first control operation. The opposite is also true. However, it is not limited to this.

The processor 620 may second monitor the output voltage level of the adapter 640 according to the second control operation (S207).

The processor 620 may determine whether the output voltage level of the adapter 640 as a result of the second monitoring is within the operating range of the adapter 640 preset in step S103 of FIG. 8 (S209).

As a result of the determination, the processor 620 charges the battery 630 when the output voltage level of the second monitoring adapter 640 is within the operating range of the adapter 640 preset in step S103 of FIG. 8. A third control operation can be performed for the current level (S211).

The processor 620 may determine whether the current output compared to the rated output of the second monitoring adapter 640 is less than or equal to the threshold, and as a result of the determination, the current output compared to the rated output of the second monitoring adapter 640 is less than or equal to the first threshold. In this case, a third control operation may be performed so that the charging current level is fixed. For example, in relation to the third control operation, the processor 620 may control the charging current level to be fixed when the current output is 5% lower than the rated output of the second monitoring adapter 640. In this case, the first threshold can be viewed as 5%, but can be set arbitrarily and is not limited to the above-mentioned value.

Meanwhile, the processor 620 may continue to monitor the output voltage level of the adapter 640 after the third control operation, that is, perform third monitoring, and the output voltage level of the adapter 640 may change according to the third monitoring result. If the change exceeds the second threshold, a fourth control operation may be performed on the charging current level. For example, in relation to the fourth control operation, if the output voltage level of the adapter 640 changes by more than 5% as a result of the third monitoring described above, the processor 620, for example, changes the current output voltage of the adapter 640. If the voltage level varies by more than 5% from the rated output voltage level of the adapter 640, that is, a voltage drop occurs, the charging current can be reduced again to compensate for the voltage drop.

Referring to (a) of FIG. 10, the battery charging method, that is, the battery charging current setting method according to an embodiment of the present disclosure, can set the charging current by classification according to system mode conditions, for example.

That is, the rated output of the adapter 640 may be determined by the sum of the charging current and the maximum system power consumption. At this time, the charging C-rate setting may not be able to use up to the rated output of the adapter 640 because the C-rate is fixed.

In the graph of Figure 10 (a), the vertical axis may represent the amount of charging current, and the horizontal axis may represent the setting mode of the display device 100.

Referring to (a) of FIG. 10, the amount of charging current is 0.5C (3.0A) when the setting mode of the display device 100 is the first mode, and 0.3C (1.8A) when the setting mode is the second mode. You can. At this time, the first mode may represent standby mode and the second mode may represent normal mode. However, it is not limited to this.

Meanwhile, standby mode may indicate a state in which the screen is turned off. In this standby mode, it is connected to a power source (e.g., adapter 640) and power can be supplied, but the screen may be turned off. In standby mode, the display device 100 may perform an operation to charge the battery 630. In this case, the display device 100 can use most of the power supplied through the adapter 640 (for example, 0.5C, 3.0A in (a) of FIG. 10) to charge the battery 630.

On the other hand, normal mode may indicate a state other than standby mode, that is, a state in which the screen is on. Accordingly, the display device 100 can use only a portion of the power supplied through the adapter 640 (for example, 0.3C, 1.8A in (a) of FIG. 10) to charge the battery 630.

Meanwhile, referring to (b) of FIG. 10, the charging current of the battery 630 is not controlled only by the simple setting mode of the display device 100 as shown in (a) of FIG. 10, but is controlled by the output of the adapter 640. You can set the charging current based on . In this case, the rated output of the adapter 640 can be expressed as the sum of system power consumption and variable charging current. In the above, the system power consumption is determined by detecting or monitoring the power consumption of the real-time display device 100, rather than presetting the maximum system power consumption, as shown in (a) of FIG. 10, and charging current based on it. Through variable control, the amount charged in the battery 630, that is, the charging current level, can be adjusted.

Referring to the graph of FIG. 10(b), the vertical axis may represent the amount of charging current and the horizontal axis may represent the output voltage of the adapter 640. Meanwhile, referring to the graph in (b) of FIG. 10, the horizontal axis, that is, the charging voltage of the adapter 640, may not be linear. For example, in Figure 10 (b), the charging voltage of the adapter 640 may not be in the form that the voltage level decreases as it approaches the central axis, and conversely, the voltage level increases as it moves away from the central axis.

Referring to the graph in (b) of FIG. 10, the processor 620 continues to monitor the output voltage level of the adapter 640 and gradually increases the charging current level from 19.8v to 18.6v, for example. . At this time, the processor 620 operates at a predetermined voltage level, that is, an operating range preset based on the adapter 640 characteristic file, that is, a normal range, for example, 19.0v or more in (b) of FIG. 10 (necessarily limited to a specific voltage). (can be a range value).

For example, when the current level increases in a step-up manner, as shown in (b) of FIG. 10, the processor 620 monitors or detects a change in the voltage level compared to the current level that is stepped up in a predetermined manner. You can. If the processor 620 determines that the monitored or detected voltage level is not within the above-described normal range (for example, when the output voltage level of the adapter 640 is 19.0v or less in (b) of FIG. 10), the battery It is possible to stop the amount of current charged by 630 from stepping up (i.e., increasing). In (b) of FIG. 10, as an example, the processor 620 increases the amount of charging current until the output voltage level of the adapter 640 is 18.6v, and then stops increasing the charging current level at that voltage level. You can.

The processor 620 can then reversely step-down the charging current level until the output voltage level of the adapter 640 is in the normal range, for example, 19.0v based on (b) of FIG. 10. there is.

The processor 620 compares the current output of the adapter with respect to the rated output of the adapter, and determines that the current output of the adapter 640 is within a threshold value (e.g., 3 to 7%, preferably 5%) relative to the rated output of the adapter. If so, the charging current can be controlled to be fixed.

Referring to FIG. 11, the processor 620 can adaptively adjust and control the current level according to the setting mode of the display device 100.

The charging time of the battery 630 can be shortened by organizing power consumption for each setting mode of the display device 100 according to an embodiment of the present disclosure.

For example, the processor 620 determines the difference in power consumption for each setting mode of the display device in advance, stores it in the memory 610, and later reads the stored information to control the current level when controlling the amount of charging current. You can.

The processor 620 does not reflect changes in power consumption for each setting mode in the current charging conditions of the display device 100 and sets the maximum power consumption as the standard. That is, the rated output of the adapter 640 can be obtained as the sum of a fixed charging current level (charge current fix) and the maximum power consumption of the display device 100.

The processor 620 may analyze the difference in power consumption for each setting mode of the display device 100 and create a display device setting mode profile (mode profile), using the difference in power consumption for each mode. Excluding the power consumption of the current mode compared to the maximum power that can be supplied, the remaining power consumption that can be supplied can be additionally supplied as a charging current to the battery 630. In this case, the rated output of the adapter 640 can be obtained as the sum of the variable charging current level and the power consumption for each setting mode of the display device 100.

Through this control operation, the processor 620 can increase the C-Rate value in the constant current (CC) section of the battery.

More specifically, referring to the graph of FIG. 11, the vertical axis may represent the charging current (maximum) level for charging, and the horizontal axis may represent the setting mode of the display device 100.

For example, referring to the graph of FIG. 11, the setting mode of the display device 100 includes screen mode (1110, 1150), sound volume control mode (1130, 1140), display brightness control mode (1120), etc. It can be included. The setting mode of the display device 100 may belong to the above-described normal mode.

When referring to the graph of FIG. 11, the processor 620 may identify the current setting mode of the display device 100. The processor 620 may step up the level of the charging current of the battery 630 according to the current setting mode of the display device 100. In this case, the processor 620 may refer to the above-described graph and description of FIG. 10(b) in relation to step-up, step-down, fixed, etc., the level of the charging current according to the identified setting mode.

When a request to change the screen mode settings is received, the processor 620 may identify the screen mode for which the change settings have been requested. For example, the screen mode 1110 in FIG. 11 may be a case in which a change request is made from the current eco mode to the vivid mode. In this case, the processor 620 may control the amount of charging current to rapidly decrease from the Th2 current level to the Th1 current level. And the processor 620 can fix the charging current level (Th1) unless a change in a special setting mode is identified.

When the above-mentioned charging current level (Th1) is fixed, the processor 620 can check whether the setting mode of the display device 100 is changed to periodic/non-periodic. And when a request for changing the setting mode, for example, display brightness 1120, is received, the processor 620 can identify the received request. If the processor 620 determines that the request to down the display brightness is requested, the processor 620 may control the amount of battery charging current to increase rapidly from the Th1 current level to the Th3 current level. And the processor 620 can control the level of the charging current to be fixed at the Th3 current level.

The processor 620 continues to determine whether a setting mode change request is received after the display brightness change request, and when a sound volume change request is received in FIG. 11, the processor 620 steps up or steps the charging current level as shown in FIG. 11. -You can control it to go down. When a sound volume down request 1130 is received, the processor 620 may step-up control the amount of charging current from the Th3 current level to the Th6 current level. Thereafter, the processor 620 may control the level of the charging current to be fixed to Th6.

Meanwhile, when the sound volume up request 1140 is received, the processor 620 may step-down control the amount of charging current from the Th6 current level to the Th4 current level. Thereafter, the processor 620 may control the level of the charging current to be fixed to Th4.

The processor 620 continues to determine whether a setting mode change request is received after the sound volume change request, and when a screen mode setting change request is received in FIG. 11, the charging current level is stepped up as shown in FIG. 11. You can control it. When a request 1150 to change the screen mode setting from vivid to eco mode is received, the processor 620 may step-up control the amount of charging current from the Th4 current level to the Th5 current level. Thereafter, the processor 620 may control the level of the charging current to be fixed to Th5.

Referring to FIG. 11, the processor 620 sharply decreases or steps down the amount of current from the previous charging current level when a request is made to change the screen mode from echo to vivid, or when a change in display brightness or sound volume is requested, etc. It can be controlled as much as possible.

On the other hand, when a request is made to change the screen mode from vivid to echo, when a request is made to lower the display brightness, or when a request to lower the sound volume is received, the processor 620 causes the amount of current to surge or step up from the previous charging current level. It can be controlled as much as possible.

In the graph of FIG. 11, the case where the processor 620 rapidly increases or decreases the current level may be changed to a step-up or step-down method.

FIG. 12 may represent the contents of FIGS. 10 and 11 as a flowchart.

FIG. 12 will be described with reference to FIGS. 10 and 11 as follows.

When charging begins (S301), the processor 620 may identify the setting mode of the display device 100 (S303).

The processor 620 may check the supply voltage level of the adapter (S311).

The processor 620 may step up the charging current if the supply voltage level of the checked adapter is spec-in, that is, within a preset normal range (S313).

On the other hand, the processor 620 may step down the charging current if the supply voltage level of the checked adapter is spec-out, that is, within a preset normal range (S315).

After step S313, the processor 620 may check, or monitor, the output voltage of the adapter again (S317).

If the output voltage level of the adapter checked in step S317 is adapter specification-in, the processor 620 can set the corresponding charging current level (S319).

On the other hand, if the output voltage level of the adapter checked in step S317 is a drop in the adapter voltage level, the processor 620 may return to step S311.

After setting the corresponding charging current level in step S319, the processor 620 may check the adapter output voltage again (S321).

The processor 620 may up or down the adapter output voltage based on the check result in step S321. However, if the processor 620 does not up/down the adapter output voltage as a result of the check in step S321, the processor 620 may wait to check whether the mode setting has been changed in step S303.

Meanwhile, the processor 620 may operate differently depending on the setting mode of the display device 100 determined in step S303.

For example, the processor 620 may perform step S311 when the setting mode is related to setting the display brightness up, but may perform step S313 when setting the display brightness down.

For example, the processor 620 may perform step S311 if the setting mode is related to setting the speaker volume, and may perform step S311 in the case of setting the sound volume up, but may perform step S313 in the case of setting the sound volume down.

For example, the processor 620 may perform step S311 if the setting mode is related to setting a screen mode, and may perform step S311 in the case of vivid mode setting, but may perform step S313 in case of setting the eco mode.

FIG. 13 is a diagram illustrating charging current control according to a difference in power consumption of a display device according to another embodiment of the present disclosure.

In relation to the present disclosure, for example, when the display device 100 uses an OLED display, power consumption varies depending on the color displayed on the screen, so the charging current and voltage level are based on that. Management control can be performed.

Referring to FIG. 13, it can be seen that power consumption varies depending on the color of the content provided on the screen, the application execution screen, etc. For example, if the content is white color-based, power consumption is high, and if the content is black color-based, power consumption is low.

Accordingly, the processor 620 can control the charging current variation using the difference in power consumption depending on the type of each content through color analysis of the content.

For example, in the case of sports such as soccer, green color may be expressed a lot, and if web services are used a lot, white color may be expressed a lot. Accordingly, the processor 620 may calculate power consumption according to the color and perform variable-fix control of the battery charging current based on the calculated power consumption.

In addition, the processor 620 (or an external server (not shown)) learns by inputting data on power consumption according to various contents through an artificial intelligence learning prediction model, and through this, execution is scheduled or requested by the user. Charging efficiency can be improved by adaptively controlling the charging current variably according to the content being used.

In relation to the present invention described above, the charging current can be increased to the adapter rated output while supplying power to the display device, and the charging variable C-Rate can be set to the maximum C-R in the battery 630 approval source. Rate can be applied.

Meanwhile, in the display device 100 according to the present disclosure, a difference in power consumption occurs depending on the display device 100 setting mode through adapter voltage current analysis and battery charging C-rate monitoring, and the existing charging method generates a difference in power consumption when charging in the CC section. While charging is performed without changing the battery C-Rate, there is a difference in charging current for each setting mode, so when changing the TV mode setting, you can check if there is a change in charging current by monitoring the rise or fall of the battery charging current.

In addition, according to at least one of the various embodiments of the present disclosure, the charging C-Rate adjustment method using adapter current/voltage monitoring varies the adapter output voltage (possible by using a power supply) to reduce the output voltage drop (Voltage Drop). ) can be created and confirmed by monitoring the change in battery charging current.

According to an embodiment of the present invention, the above-described method can be implemented as processor-readable code on a program-recorded medium. Examples of media that the processor can read include ROM, RAM, CD-ROM, magnetic tape, floppy disk, and optical data storage devices.

The display device described above is not limited to the configuration and method of the above-described embodiments, and the embodiments may be configured by selectively combining all or part of each embodiment so that various modifications can be made. It may be possible.

According to the display device according to the present disclosure, the charging efficiency of the battery based on the rated power of the adapter is improved based on various data, and thus has industrial applicability.
