[0050] In addition, the user input interface 150 can transmit control signals input from local keys (not shown) such as a power key, a channel key, a volume key, and a setting key to the controller 170.

[0051] The video signal processed in the controller 170 can be input to the display 180 and displayed as a video corresponding to the video signal. Additionally, the video signal processed in the controller 170 can be input to an external output device through the external device interface 135.

[0052] The voice signal processed in the controller 170 can be output as audio from the speaker 185. Additionally, the voice signal processed in the controller 170 can be input to an external output device through the external device interface 135.

[0053] In addition, the controller 170 can control the overall operation within the display device 100.

[0054] Furthermore, the controller 170 can control the display device 100 through user instructions input via the user input interface 150 or an internal program, and can download an application or application directory desired by the user into the display device 100 by connecting to a network.

[0055] The controller 170 can output the channel information selected by the user, etc., together with the processed video or voice signal through the display 180 or the speaker 185.

[0056] Additionally, the controller 170 can, according to an external device video playback instruction received through the user input interface 150, output a video signal or voice signal from an external device such as a camera or a video camera input through the external device interface 135 through the display 180 or the speaker 185.

[0063] On the other hand, Figure 1The illustrated display device 100 is merely an embodiment of the present invention, and some of the illustrated components may be integrated, added, or omitted according to the specifications of the actually implemented display device 100.

[0064] That is, as needed, two or more components may be integrated into one component, or one component may be subdivided into two or more components. In addition, the functions executed in each block are used to illustrate the embodiments of the present invention, and the specific actions or devices do not limit the scope of the rights of the present invention.

[0065] According to another embodiment of the present invention, the display device 100 may also Figure 1 differently from that shown, receive and play images through the network interface 133 or the external device interface 135, and does not have the tuner 131 and the demodulator 132.

[0066] For example, the display device 100 may be separately implemented as an image processing device such as a set-top box for receiving broadcast signals or content under various network services, and a content playback device for playing the content input from the image processing device.

[0086] Redescription Figure 2 .

[0087] If the user input interface 230 has a touch screen, the user can input instructions related to the display device 100 to the remote control device 200 by touching the soft keys on the touch screen. In addition, the user input interface 230 can have various types of input means that the user can operate, such as scroll keys or nudge keys. However, this embodiment does not limit the scope of the rights of the present invention.

[0088] The sensor 240 can have a gyro sensor 241 or an acceleration sensor 243. The gyro sensor 241 can sense information related to the movement of the remote control device 200.

[0089] For example, the gyro sensor 241 can sense information related to the movement of the remote control device 200 based on the x, y, and z axes, and the acceleration sensor 243 can sense information related to the moving speed of the remote control device 200, etc. On the other hand, the remote control device 200 can also have a distance measurement sensor that can sense the distance to the display 180 of the display device 100.

[0090] The output interface 250 can output video or audio signals corresponding to the operation of the user input interface 230 or corresponding to the signals transmitted from the display device 100.

[0091] The user can identify whether the user input interface 230 is operated or whether the display device 100 is controlled through the output interface 250.

[0092] For example, the output interface 250 may include an LED 251, a vibrator 253 that generates vibration, a speaker 255 that outputs sound, or a display 257 that outputs an image. Among them, the LED 251 is lit when the user input interface 230 is operated or when signals are transmitted and received with the display device 100 through the wireless communication unit 225.

[0093] In addition, the power supply circuit 260 supplies power to the remote control device 200. If the remote control device 200 does not move during a specified period of time, the power supply is stopped, thereby reducing power waste.

[0094] If a specified key provided on the remote control device 200 is operated, the power supply circuit 260 can restart the power supply.

[0095] The memory 270 can store various programs, application program data, etc. required for the control or operation of the remote control device 200.

[0096] If the remote control device 200 and the display device 100 wirelessly transmit and receive signals through the RF circuit 221, the remote control device 200 and the display device 100 transmit and receive signals through a specified frequency band.

[0097] The controller 280 of the remote control device 200 can store and refer to information related to the frequency band, etc. in the memory 270. The "frequency band" refers to the frequency band that can wirelessly transmit and receive signals with the display device 100 paired with the remote control device 200.

[0098] The controller 280 controls all matters related to the control of the remote control device 200. The controller 280 can transmit a signal corresponding to the operation of a specified key of the user input interface 230 or a signal corresponding to the movement of the remote control device 200 sensed by the sensor 240 to the display device 100 through the wireless communication unit 225.

[0099] In addition, a microphone 290 of the remote control device 200 can acquire voice.

[0100] There may be a plurality of microphones 290.

[0101] Next, an explanation will be given Figure 4 。

[0102] Figure 4 An example of applying the remote control device 200 according to an embodiment of the present invention is shown.

[0103] Figure 4 Example (a) of illustrates a pointer 205 corresponding to the remote control device 200 being displayed on the display 180.

[0104] The user can move the remote control device 200 up and down, left and right, or rotate it. The pointer 205 displayed on the display 180 of the display device 100 corresponds to the movement of the remote control device 200. As shown in the figure, this kind of remote control device 200 moves and displays the corresponding pointer 205 according to the movement in the 3D space, so it can be named "spatial remote control".

[0105] Figure 4 Example (b) shows that when the user moves the remote control device 200 to the left, the pointer 205 displayed on the display 180 of the display device 100 also moves to the left accordingly.

[0106] The information about the movement of the remote control device 200 sensed by the sensors of the remote control device 200 is transmitted to the display device 100. The display device 100 can calculate the coordinates of the pointer 205 from the information related to the movement of the remote control device 200. The display device 100 can display the pointer 205 corresponding to the calculated coordinates.

[0107] Figure 4 Example (c) shows the situation where, in the state of pressing a specific key inside the remote control device 200, the user moves the remote control device 200 away from the display device 180. As a result, the selection area corresponding to the pointer 205 inside the display 180 can be enlarged and displayed.

[0108] On the contrary, if the user moves the remote control device 200 closer to the display 180, the selection area corresponding to the pointer 205 inside the display 180 can be reduced and displayed.

[0109] On the other hand, it can also be: if the remote control device 200 is away from the display 180, the selection area is reduced; if the remote control device 200 is close to the display 180, the selection area is enlarged.

[0110] In addition, in the state of pressing a specific key inside the remote control device 200, the recognition of up, down, left, and right movements is excluded. That is, if the remote control device 200 moves away from or closer to the display 180, the up, down, left, and right movements are not recognized, and only the forward and backward movements are recognized. In the state of not pressing the specific key in the remote control device 200, only the pointer 205 moves as the remote control device 200 moves up, down, left, and right.

[0111] On the other hand, the moving speed or moving direction of the pointer 205 can correspond to the moving speed or moving direction of the remote control device 200.

[0112] On the other hand, the "pointer" in this specification refers to an object displayed on the display 180 corresponding to the operation of the remote control device 200. Therefore, in addition to the arrow shape illustrated by the pointer 205 in the drawings, the object can be in various shapes, such as concepts including a point, a cursor, a prompt, a thick outline, etc. In addition, the pointer 205 can be displayed corresponding to not only a certain position (point) on the horizontal axis and the vertical axis on the display 180, but also a plurality of positions such as a line and a surface.

[0113] Figure 5 FIGs. are diagrams for explaining the landscape mode and the portrait mode of the vertical display device according to an embodiment of the present disclosure.

[0114] Refer to Figure 5 (a) of Figure 5 and (b) of

[0119] The display device 100 and the connecting shaft 103 may rotate relative to the bracket base 105 about a vertical axis.

[0120] The upper portion of the connecting shaft 103 may be connected to the back surface of the display device 100.

[0121] The bracket base 105 may function to support the display device 100.

[0122] The display device 100 may be configured to include the connecting shaft 103 and the bracket base 105.

[0123] The display device 100 may rotate about the position where the upper portion of the connecting shaft 103 contacts the back surface of the display 180.

[0124] Figure 5 (a) of Figure 5 represents an operation in the landscape mode, that is, a posture in which the horizontal length of the display 180 is greater than the vertical length, (b) of represents an operation in the landscape mode, that is, a posture in which the vertical length of the display 180 is greater than the horizontal length.

[0125] The user can move while carrying the vertical display device. That is, unlike a fixed device, the vertical display device 100 not only has improved mobility but also the user is not restricted by the configuration position.

[0130] The processor 620 may calculate the power consumption of the display device 100 by detecting the voltage level and current level of the adapter 640. If the calculated power consumption is less than the rated output of the preset adapter 640, the processor 620 may perform a control action to change the charging current level of the battery 630.

[0131] Refer to Figure 6 , the display device 100 may include a display 180, a processing unit 600, and a battery 630.

[0132] The adapter 640 may supply power to the display device 100 or charge the battery 630.

[0133] For the display 180, reference may be made to the content described in the foregoing Figures 1 to 5 , and repeated descriptions are omitted here.

[0134] The display 180 may receive the control of the processing unit 600 and output the information of the battery 630 to an area on the screen.

[0135] The processing unit 600 may be configured to include a memory 610 and a processor 620.

[0136] The memory 610 may store information such as the battery 630 and the adapter 640, and may continue to update the information of the battery 630 collected in real time.

[0137] The processor 620 can control the power required to drive the display device 100 supplied by the adapter 640, and in this process, can control the charging speed by controlling the current level for charging the battery 630.

[0138] In the process of controlling the current level for charging the battery 630, the processor 620 can monitor the voltage level under the current level control. The processor 620 can readjust the current level for charging the battery 630 based on the voltage level monitoring result.

[0139] Refer to Figure 7 to illustrate the detailed control actions of the voltage-current level of the adapter 640 of the processor 620.

[0140] Refer to Figure 7 The processor 620 can be configured to include a sensing module 710, a charger block 720, and a control module 730. According to an embodiment, at least one of the listed multiple components can be implemented as a separate component outside the processor 620, or can be included in the control module 730.

[0141] The sensing module 710 can sense the supply voltage level and / or current level of the adapter 640. The sensing module 710 can include an R-Sensing component for specifically sensing the current level.

[0142] The charging module 720 can supply the current for charging the battery 630 by using the rated output of the adapter 640, that is, the power supplied by the adapter 640.

[0143] The control module 730 can control the current level supplied for charging the battery 630 by controlling the sensing module 710 and the charging module 720.

[0144] On the other hand, although not illustrated in Figures 6 to 7 , the processing unit 600 or the processor 620 may further include a communication module. At this time, the communication module supports a wired or wireless communication protocol and can support the data transceiver process for data communication with the adapter 640 and at least one or more external devices (such as a user terminal, a remote controller, etc.).

[0145] Figure 8 and Figure 9 are sequence diagrams shown to illustrate the operation method of the display device 100 according to an embodiment of the present disclosure.

[0146] Figure 10 and Figure 11FIG. is a diagram for explaining the charging current control of the display device 100 in the setting mode according to an embodiment of the present disclosure.

[0147] Figure 12 FIG. is a sequence diagram for explaining the charging current control of the display device 100 in the setting mode according to an embodiment of the present disclosure.

[0148] Figure 8 And Figure 9 Explain the operation of the processor 620 in the processing unit of the display device 100, which is to charge the battery 630 based on the power supplied by the adapter 640.

[0149] First, referring to Figure 8 , the processor 620 may generate an adapter characteristic curve (S101).

[0150] The processor 620 may set the output voltage operation range of the adapter 640 based on the adapter characteristic curve (S103).

[0151] The processor 620 may calculate the power consumption of the display device 100 by detecting the voltage level and current level of the adapter 640 (S105).

[0152] The processor 620 may determine whether the power consumption calculated in step S105 is less than the rated output of the adapter 640 (S107).

[0153] According to the determination result of step S107, if 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 action on the current level for charging the battery 630 (S109).

[0154] Here, the first control action may be an action of gradually increasing the current level for charging the battery 630. At this time, the control of "gradually increasing" may indicate linear increase or step-up (refer to Figure 10 (b)) the control action of the current level. However, it is not limited thereto. In this specification, "gradually increasing" may also include any form (non-linear) in which the current level increases according to the voltage level (for example, within the operation range of the output voltage of the adapter 640 set in step S103).

[0155] Secondly, referring to Figure 9 , the processor 620 may perform a first monitoring on the output voltage level of the adapter 640 (S201).

[0156] The processor 620 may determine whether the output voltage level of the adapter 640 monitored for the first time exceeds the aforementioned Figure 8The operation range (S203) of the preset adapter output voltage in step S103.

[0157] According to the determination result, if the output voltage level of the first monitored adapter 640 exceeds the operation range of the adapter output voltage set in step S103 of the foregoing Figure 8 The processor 620 may perform a second control action (S205) on the current level for charging the battery 630 that is under the first control. Here, the second control action may be an action of controlling the reduction of the current level for charging the battery 630 differently from the foregoing first control action. According to an embodiment, the increasing slope and the decreasing slope respectively added in the first control action and the second control action may be symmetric with each other (or the same in terms of view), or may be asymmetric. For example, it may be that the slope of the current level gradually decreasing according to the second control action is smaller than the slope of the current level gradually increasing according to the first control action. Vice versa. However, it is not limited thereto.

[0158] The processor 620 may perform a second monitoring (S207) on the output voltage level of the adapter 640 under the second control action.

[0159] Based on the second monitoring result, the processor 620 may determine whether the output voltage level of the adapter 640 is within the operation range of the adapter 640 preset in step S103 of the foregoing Figure 8 (S209).

[0160] According to the determination result, if the output voltage level of the second monitored adapter 640 is within the operation range of the adapter 640 preset in step S103 of the foregoing Figure 8 The processor 620 may perform a third control action (S211) on the current level for charging the battery 630.

[0161] The processor 620 may determine whether the current output is below the critical value compared with the rated output of the second monitored adapter 640. According to the determination result, if the current output is below the first critical value compared with the rated output of the second monitored adapter 640, the third control action may be performed to fix the charging current level. For example, regarding the third control action, if the current output is 5% lower than the rated output of the second monitored adapter 640, the processor 620 may control the charging current level to be fixed. In this case, the first critical value may be regarded as 5%, and it can be set arbitrarily and is not limited to the above value.

[0162] On the other hand, after the third control action, the processor 620 can continue to monitor the output voltage level of the adapter 640, that is, perform the third monitoring. According to the result of the third monitoring, if the output voltage level of the adapter 640 changes by more than the second critical value, the fourth control action can be performed on the charging current level. For example, regarding the fourth control action, according to the aforementioned result of the third monitoring, if the output voltage level of the adapter 640 changes by more than 5%, for example, if the current output voltage level of the adapter 640 changes by more than 5% compared to 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.

[0163] Referring to Figure 10 (a) of, the battery charging method, that is, the battery charging current setting method, of an embodiment of the present disclosure can set the charging current by classifying according to system mode conditions, for example.

[0164] That is, the rated output of the adapter 640 can be determined by the sum of the charging current and the maximum system power consumption. At this time, since the C-rate is fixed, the charging C-rate setting may not be able to use the rated output of the adapter 640.

[0165] In Figure 10 (a) of the curve graph, the vertical axis can represent the charging current amount, and the horizontal axis can represent the setting mode of the display device 100.

[0166] Referring to Figure 10 (a) of, when the setting mode of the display device 100 is the first mode, the charging current amount can be 0.5C (3.0A), and when it is the second mode, the charging current amount can be 0.3C (1.8A). At this time, the first mode can represent the standby mode, and the second mode can represent the normal mode. However, it is not limited thereto.

[0167] On the other hand, the "standby mode" can represent a state where the screen is turned off. This standby mode can represent a state where it is connected to a power source (such as the adapter 640) and can supply power but the screen is turned off. In the standby mode, the display device 100 can perform an action of charging the battery 630. In this case, the display device 100 can use most of the power supplied through the adapter 640 (such as Figure 10 0.5C, 3.0A in (a) of) for charging the battery 630.

[0168] On the contrary, the "normal mode" can represent a state that is not the standby mode, that is, a state where the screen is turned on. Therefore, the display device 100 can only use a part of the power supplied through the adapter 640 (such asFigure 10 0.3C, 1.8A) in (a) is used to charge battery 630.

[0169] On the other hand, refer to Figure 10 (b) can set the charging current based on the output of the adapter 640, unlike the aforementioned Figure 10 The charging current of the battery 630 is controlled simply by the setting mode of the display device 100 as shown in (a). In this case, the rated output of the adapter 640 can be represented by the sum of the system power consumption and the variable charging current. Figure 10 Instead of presetting the maximum power consumption of the system as shown in (a), the power consumption of the display device 100 is detected or monitored in real time, and the charging current is variably controlled based on this to adjust the amount of charge to the battery 630, that is, the charging current level.

[0170] Reference Figure 10 In the curve graph (b), the vertical axis may represent the charging current, and the horizontal axis may represent the output voltage of the adapter 640. Figure 10 In the curve diagram (b), the horizontal axis, i.e., the charging voltage of the adapter 640, may not be linear. Figure 10 In (b), the charging voltage of the adapter 640 may not be in a form where the voltage level decreases as it approaches the central axis, but rather increases as it moves away from the central axis.

[0171] Reference Figure 10 The processor 620 can continue to monitor the output voltage level of the adapter 640, and can gradually increase the charging current level until, for example, it changes from 19.8V to 18.6V. At this time, the processor 620 can set a specified voltage level, that is, an action range pre-set based on the adapter 640 characteristic file, that is, a normal range, for example, Figure 10 In (b), 19.0V or above (it may not be limited to a specific voltage but a range of values).

[0172] For example, Figure 10 As shown in (b), when the processor 620 increases the current level in a step-by-step manner, the change of the voltage level relative to the current level that is increased in a step-by-step manner in a preset manner can be monitored or detected. When the processor 620 determines that the monitored or detected voltage level is not within the normal range (for example, Figure 10 In the case where the output voltage level of the adapter 640 is below 19.0V in (b), the stepwise increase (i.e., increase) of the current amount charging the battery 630 can be interrupted. Figure 10In (b) as an example, the processor 620 may increase the charging current amount to the extent that the output voltage level of the adapter 640 is 18.6V, and interrupt the increase in the charging current level at the corresponding voltage level.

[0173] After that, the processor 620 may conversely step-down the charging current level until the output voltage level of the adapter 640 becomes within the normal range. For example, based on (b), it becomes 19.0V. Figure 10 Based on (b) as a reference, it becomes 19.0V.

[0174] The processor 620 compares the output of the current adapter with the rated output of the adapter. If the output of the current adapter 640 is a critical value (such as the aforementioned 3 to 7%, preferably 5%) relative to the rated output of the adapter, it may be controlled to fix the charging current.

[0175] Referring to Figure 11 , the processor 620 may adaptively adjust the control current level according to the setting mode of the display device 100.

[0176] According to an embodiment of the present disclosure, by sorting out the power consumption in different setting modes of the display device 100, the charging time of the battery 630 can be shortened.

[0177] For example, the processor 620 pre-understands the power consumption differences in different setting modes of the display device and stores them in the memory 610. When controlling the charging current amount afterwards, it reads out the stored information and uses it for current level control.

[0178] Under the current charging conditions of the display device 100, the processor 620 does not reflect the power consumption changes in different setting modes, but sets based on the maximum power consumption. That is, the rated output of the adapter 640 can be obtained by adding the fixed charging current level (charging current fix) and the maximum power consumption of the display device 100.

[0179] The processor 620 may analyze the power consumption differences of the display device 100 in different setting modes to generate a display device setting mode profile. At this time, using the power consumption differences in each mode, the remaining available power supply after deducting the power consumption of the current mode from the maximum available power supply is additionally supplied as the charging current of the battery 630. In this case, the rated output of the adapter 640 can be obtained by adding the variable charging current level and the power consumption in different setting modes of the display device 100.

[0180] The processor 620 can increase the C-Rate value in the constant current (CC: Constant Current) section of the battery through such control actions.

[0181] More specifically, referring to Figure 11 the curve graph of

[0182] "The setting mode of the display device 100" means, for example, referring to Figure 11 the curve graph of

[0183] When referring to Figure 11 the curve graph of Figure 10 the curve graph and description of (b) of

[0184] When the processor 620 receives a request for changing the setting of the screen mode, it can identify the screen mode for which the setting change is requested. For example, in Figure 11 the screen mode 1110 can be an example of a request to change from the current eco mode to the vivid mode. In this case, the processor 620 can control the charging current amount to suddenly decrease from the current level Th2 to the current level Th1. In addition, unless the processor 620 identifies a change in a special setting mode or the like, it can fix the charging current amount at the charging current level Th1.

[0185] When the processor 620 is fixed at the aforementioned charging current level Th1, it can periodically or aperiodically confirm whether there is a change in the setting mode of the display device 100. In addition, when the processor 620 receives a setting mode change, for example, when it receives a request 1120 for changing the display brightness, it can identify the received request. According to the identification result, if it is identified as a request for decreasing the display brightness, the processor 620 can control to suddenly increase the battery charging current amount from the current level Th1 to the current level Th3. In addition, the processor 620 can fix the charging current level at the current level Th3.

[0186] After the request for changing the display brightness, the processor 620 continues to determine whether it receives a request for changing the setting mode. In Figure 11 if it receives a request for changing the sound volume, then as in Figure 11As shown, it can be controlled to increase or decrease the charging current level step by step. When the processor 620 receives the sound volume decrease request 1130, it can increase the charging current amount step by step from the current level Th3 to the current level Th6. After that, the processor 620 can be controlled to fix the charging current level at Th6.

[0187] On the other hand, when the processor 620 receives the sound volume increase request 1140, it can be controlled to decrease the charging current amount step by step from the current level Th6 to the current level Th4. After that, the processor 620 can be controlled to fix the charging current level at Th4.

[0188] After the sound volume change request, the processor 620 continues to determine whether a setting mode change request is received. In Figure 11 if a screen mode setting change request is received, then as Figure 11 shown, it can be controlled to increase the charging current level step by step. When the processor 620 receives the request 1150 to change the screen mode setting from vivid to power saving mode, it can be controlled to increase the charging current amount step by step from the current level Th4 to the current level Th5. After that, the processor 620 can be controlled to fix the charging current level at Th5.

[0189] Referring to Figure 11 when the processor 620 is requested to change the screen mode from power saving to vivid, if a request to increase the display brightness, increase the sound volume, etc. is received, it can be controlled to suddenly decrease or decrease step by step the current amount from the previous charging current level.

[0190] On the contrary, when the processor 620 receives a request to change the screen mode from vivid to power saving, receives a request to decrease the display brightness, receives a request to decrease the sound volume, etc., it can be controlled to suddenly increase or increase step by step the current amount from the previous charging current level.

[0191] In Figure 11 the curve graph, the situation where the current level suddenly increases or decreases in the processor 620 can also be changed to a step - by - step increase or step - by - step decrease mode.

[0192] Figure 12 It can be a diagram that shows the content of Figures 10 to 11 in a sequence diagram.

[0193] Referring to Figures 10 to 11 the explanation is Figure 12 as follows.

[0194] If charging starts (S301), then the processor 620 can identify the setting mode of the display device 100 (S303).

[0195] The processor 620 may check the supply voltage level of the adapter (S311).

[0196] If the supply voltage level of the checked adapter is within the specification range (Spec-in), that is, within the preset normal range, the processor 620 may increment the charging current step by step (S313).

[0197] On the contrary, if the supply voltage level of the checked adapter exceeds the specification range (Spec-out), that is, not within the preset normal range, the processor 620 may decrement the charging current step by step (S315).

[0198] The processor 620 may check, that is, monitor the output voltage of the adapter again after step S313 (S317).

[0199] If the output voltage level of the adapter checked in step S317 is within the adapter specification range, the processor 620 may set the corresponding charging current level (S319).

[0200] On the contrary, if the output voltage level of the adapter checked in step S317 shows a drop in the adapter voltage level, the processor 620 may return to step S311.

[0201] After setting the corresponding charging current level in step S319, the processor 620 may check the adapter output voltage again (S321).

[0202] The processor 620 may increase or decrease the adapter output voltage based on the check result of step S321. However, when the adapter output voltage does not increase or decrease in the check result of step S321, the processor 620 may wait to confirm whether there is a change in the mode setting in step S303.

[0203] On the other hand, the operation of the processor 620 may vary according to the setting mode of the display device 100 determined in step S303.

[0204] For example, when the setting mode involves the display brightness setting and the display brightness is set to increase, the processor 620 may execute step S311, but when the display brightness is set to decrease, the processor 620 may execute step S313.

[0205] For example, when the setting mode involves the speaker volume setting and the sound volume is set to increase, the processor 620 may execute step S311, but when the sound volume is set to decrease, the processor 620 may execute step S313.

[0206] For example, when the setting mode of the processor 620 involves screen mode setting and vivid mode setting, the step S311 can be executed, but when the power saving mode is set, the step S313 can be executed.

[0207] Figure 13 FIG. is a diagram for explaining the charging current control under the power consumption difference of the display device according to another embodiment of the present disclosure.

[0208] Regarding the present disclosure, for example, when the display device 100 uses an OLED display, since there is a power consumption difference according to the color presented in the screen, charging current and voltage level management control can be performed based on this.

[0209] Referring to Figure 13 , it can be known that the power consumption varies according to the color of the content provided through the screen, the application execution screen, etc. For example, it can be known that if the content has a white background, the power consumption is high, and if it has a black background, the power consumption is low.

[0210] Therefore, the processor 620 can analyze the color of the content and use the power consumption difference under various contents to variably control the charging current.

[0211] For example, in the case of sports programs such as football, it is mostly green, and in the case of mostly using network services, it is mostly white. Therefore, the processor 620 can calculate the power consumption according to different colors and perform variable-fixed control of the battery charging current based on the calculated power consumption.

[0212] Furthermore, the processor 620 (or an external server (not shown)) can use an artificial intelligence learning prediction model to learn by taking the power consumption-related data under various contents as input. Thus, according to the content reserved or requested by the user, the charging current can be adaptively variably controlled, thereby improving the charging efficiency.

[0213] Regarding the above-mentioned present invention, in the state where power is supplied to the display device, by increasing the charging current, the rated output of the adapter can be used, so that the maximum C-Rate in the charging variable C-Rate applicable battery 630 approval source can be achieved.

[0214] On the other hand, the display device 100 of the present disclosure has a power consumption difference according to different setting modes of the display device 100 through adapter voltage-current analysis and battery charging C-Rate monitoring. In contrast, the existing charging method charges the battery C-Rate without change during the CC interval charging. On the contrary, the present disclosure has a difference in charging current according to different setting modes. Therefore, when changing the TV mode setting, it is possible to confirm whether there is a change in the charging current by monitoring whether the battery charging current increases or decreases.

[0215] In addition, according to at least one embodiment among various embodiments of the present disclosure, a charging C-Rate adjustment method using adapter current or voltage monitoring can create an interval in which an output voltage drop occurs by changing the adapter output voltage (which can be achieved if using a power supply), and at this time, the change in the battery charging current can be confirmed through monitoring.

[0216] According to an embodiment of the present invention, the foregoing method can be implemented by a processor with code readable in a medium recording a program. As examples of a processor-readable medium, there are ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage device, and the like.

[0217] As described above, the display device described is not limited to the configurations and methods of the above-described embodiments, and the respective embodiments can be selectively combined in whole or in part to enable various modifications of the respective embodiments.
