For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be utilized.The display device (100) can provide an ultra-low latency service, for example, by using distributed computing or mobile edge computing. The electronic device (104) can include an IoT (Internet of Things) device. The server (105) can be an intelligent server using machine learning and / or a neural network.

The components may be connected to each other based on a specific communication method (e.g., a bus, a general purpose input and output (GPIO), a serial peripheral interface (SPI), or a mobile industry processor interface (MIPI)), or may exchange signals (e.g., commands or data) with each other. The components are merely examples. For example, the display device (100) may include other components (e.g., a power management integrated circuit (PMIC), a connection terminal, or an input / output interface). At least one of the components included in the display device (100) may be omitted, or one or more other components may be added. Some of the components included in the above display device (100) may be integrated into one component.

[0021] The processor (110) may execute software (e.g., an application program, a driving program, and / or a system program) to control at least one other component (e.g., a hardware or software component) of the display device (100). To this end, the processor (110) may perform various data processing and / or operations. As at least a part of the data processing and / or operations, the processor (110) may store commands or data received from other components (e.g., a communication circuit (120) or a sensor (130)) in the volatile memory (161). The processor (110) may process commands or data stored in the volatile memory (161) and store resulting data in the non-volatile memory (162).

[0022] The processor (110) may be implemented as one or more integrated circuit (IC) chips and may perform various data processing operations. For example, the processor (110) (or application processor (AP)) may be implemented as a system on chip (SoC) (e.g., a single chip or chipset). The processor (110) may include sub-components including a central processing unit (CPU) (111), a neural processing unit (NPU) (112), a graphics processing unit (GPU) (113), a communication processor (CP) (114), a sensor interface (115), an audio controller (116), a display controller (117), a memory controller (118), and / or a storage controller (119). The sub-components are merely examples. For example, the processor (110) may further include other sub-components (e.g., an image signal processor (ISP)). For example, some sub-components may be omitted from the processor (110). For example, some sub-components may be included as separate components of the display device (100) outside of the processor (110). For example, some sub-components may be included within other components (e.g., the display (150)). The processor (110) may include various processing circuits and / or multiple processors. For example, as used in this disclosure, including the claims, the term “processor” may include various processing circuits including at least one processor, wherein one or more of the at least one processor may be configured to perform various functions described in this disclosure in an individually and / or collectively distributed manner.When "processor," "at least one processor," and "one or more processors" are described herein as being configured to perform multiple functions, these terms include, but are not limited to, situations where one processor performs some of the recited functions, another processor performs other of the recited functions, and situations where a single processor performs all of the recited functions. Furthermore, the at least one processor may comprise a combination of processors that perform various recited / disclosed functions, for example, in a distributed manner. At least one processor may execute program instructions to achieve or perform various functions.

[0023] The CPU (111) (or central processing circuit) may be configured to control sub-components based on the execution of instructions stored in the memory (160) (e.g., volatile memory (161) and / or non-volatile memory (162)). The NPU (112) (or neural processing circuit) may be configured to execute operations for an artificial intelligence model (e.g., convolution computation). The GPU (113) (or graphics processing circuit) may be configured to execute parallel operations (e.g., rendering). The CP (114) (or communication processing circuit) may be configured to process data obtained from a sub-component within the processor (110) into a format suitable for transmission to another electronic device (e.g., electronic device (103, 104) or server (105)) via the communication circuit (120), or to process data obtained from another electronic device (e.g., electronic device (103, 104) or server (105)) via the communication circuit (130) into a format suitable for processing in the sub-component. The sensor interface (115) (or sensing data processing circuit, sensor hub) may be configured to process data on the status of the display device (100) and / or the status of the surroundings of the display device (100), obtained via the sensor (130), into a format suitable for the sub-component of the processor (110). The audio controller (116) (or audio control circuit) may be configured to process an audio signal obtained from the memory (160) (e.g., volatile memory (161)) by the CPU (111) or the memory controller (118) into an audible signal suitable for outputting through the speaker (140).The display controller (118) (or display control circuit) may be configured to process an image acquired from the memory (160) (e.g., volatile memory (161)) by the CPU (111), the GPU (113), or the memory controller (118) into a format suitable for output by the display (150). The memory controller (118) (or memory control circuit) may be configured to control reading data from the volatile memory (161) or writing data to the volatile memory (161). The storage controller (119) (or storage control circuit) may be configured to control reading data from the non-volatile memory (162) or writing data to the non-volatile memory (162).

[0024] When the display device (100) includes a main processor (e.g., CPU (111)) and an auxiliary processor (e.g., NPU (112), GPU (113), CP (114), sensor interface (115), audio controller (116), display controller (117), memory controller (118) and / or storage controller (119)), depending on the operating mode (e.g., power saving mode), the auxiliary processor may be configured to use less power than the main processor or to be specialized for a specified function. The auxiliary processor may be implemented separately from the main processor or as a part thereof.

[0025] The display device (100) may consume power in accordance with its operating mode. Hereinafter, the power consumed by the display device (100) may be referred to as “power consumption.” The operating mode may include, for example, a normal mode, a low power mode (LPM), a background suspend mode, an always-on screen / ambient mode, a picture-off mode, or a suspend mode. The normal mode may be an operating mode in which both video and audio may be output. The LPM may be an operating mode in which power consumption is minimized and / or reduced in a standby state. In the LPM, the display device (100) may use only the amount of power consumed to receive a signal from a remote control device. The background screen mode may be an operating mode in which a preset image is displayed as a background screen through the display. The always-on display mode may be an operating mode in which a screen is continuously displayed through the display. The above picture-off mode may be an operating mode that turns off video output and turns on only audio output. The above picture-off mode may be, for example, a music appreciation mode. The above pause mode may be an operating mode in which all operations by the display device (100) are temporarily suspended.

[0026] The display device (100) may have different power consumption depending on the operation mode. This is because the display device (100) may drive different modules depending on the operation mode. In the basic mode, modules corresponding to a back light unit (BLU), cells constituting the panel, a main board, and a speaker may be driven. Accordingly, the processor (110) may accumulate the power consumption (hereinafter referred to as “individual power consumption”) of each of the BLU, cells, the main board, and the speaker to obtain the power consumption (hereinafter referred to as “total power consumption”) in the basic mode. In the LPM, a module corresponding to the main board may be driven. Accordingly, the processor (110) may obtain the individual power consumption due to the main board operating at low power as the total power consumption in the LPM. In the background screen mode, a module corresponding to the main board may be driven. Accordingly, the processor (110) can obtain the individual power consumption of the main board as the total power consumption in the background screen mode. In the constant display display mode, modules corresponding to the BLU, cells, and the main board can be driven. Therefore, the processor (110) can accumulate the individual power consumption of each of the BLU, cells, and the main board to obtain the total power consumption in the constant display display mode. In the picture-off mode, modules corresponding to the main board and the speaker can be driven. Therefore, the processor (110) can accumulate the individual power consumption of each of the main board and the speaker to obtain the total power consumption in the picture-off mode. In the pause mode, no module is driven. Therefore, the processor (110) can determine the total power consumption in both the pause modes as "0".

[0027] The processor (110) can obtain the power consumption (or energy consumption) by predicting or calculating the individual power consumption for each module according to the operation mode of the display device (100). The processor (110) can obtain the power consumption, for example, by calculating or predicting the power consumption. The power consumption may refer to the amount of power (WH) consumed by at least one module for a predetermined period of time (e.g., 1 hour) due to the operation of the display device (100). The power consumption may include the individual power consumption or the total power consumption. The individual power consumption may be the power consumption calculated or predicted for each module according to the operation mode of the display device (100). The module may include at least one component that provides a predetermined function in the display device (100). The component may be one of a BLU, a cell, a main board, and a speaker. The module may include a unit implemented as hardware (H / W), software (S / W), or firmware. The above module may be used interchangeably with terms such as logic, logic block, component, or circuit, for example. The module may be an integral component or a minimum unit or part of the component that performs one or more functions. For example, the module may be implemented in the form of an application-specific integrated circuit (ASIC). Specific functions that may be provided by the module may include an operation for driving a backlight, an operation for outputting video of a predetermined quality (e.g., resolution or average picture level (APL)), an operation for processing a video signal, or an operation for processing or outputting an audio signal. The module may include, for example, a backlight driving module that performs an operation for driving a backlight.The module may include, for example, a video output module that performs an operation for outputting a video of a predetermined quality (e.g., resolution or average picture level (APL)). The module may include, for example, a video signal processing module that performs an operation for processing a video signal. The module may include, for example, an audio signal processing / output module that performs an operation for processing or outputting an audio signal. As an example, the module may include one or more modules from among the modules listed above. The total power consumption may be obtained by accumulating one or more individual power consumption amounts from among the individual power consumption amounts.

[0028] The processor (110) can calculate or predict individual power consumption for each detailed operation item. For example, the processor (110) can calculate power consumption (P) from a light source such as a backlight. BLU ) (hereinafter referred to as “light source power consumption” or “first individual power consumption”) can be calculated or predicted as individual power consumption. The processor (110) may calculate or predict, for example, the power consumption (P) according to the quality of the output image. CELL ) (hereinafter referred to as “cell power consumption” or “second individual power consumption”) can be calculated or predicted as individual power consumption. The processor (110) may, for example, calculate the power consumption (P) for processing an image signal in a specific circuit (e.g., main board). MAIN ) (hereinafter referred to as “video processing power consumption” or “third individual power consumption”) can be calculated or predicted as individual power consumption. The processor (110) may, for example, calculate the power consumption (P) for processing and outputting an audio signal. SPEAKER) (hereinafter referred to as “audio processing power consumption” or “fourth individual power consumption”) can be calculated or predicted as individual power consumption. The first to fourth individual power consumptions may differ depending on the operation mode of the display device (100).

[0029] The processor (110) may have a relatively reduced power consumption (e.g., at least one of the first to fourth individual power consumptions) when operating in the picture-off mode compared to the basic mode. The processor (110) may have a relatively reduced power consumption (e.g., at least one of the first to fourth individual power consumptions) when operating in the LPM compared to the picture-off mode.

[0030] The processor (110) can obtain the total power consumption for each operation mode. The total power consumption may vary depending on the operation mode of the display device (100). The processor (110) may relatively reduce the power consumption (e.g., total power consumption) when operating in the picture-off mode compared to the basic mode. The processor (110) may relatively reduce the power consumption (e.g., total power consumption) when operating in the LPM compared to the picture-off mode. The total power consumption corresponding to each operation mode may be obtained by calculating or integrating one or more predicted detailed power consumption amounts when the display device (100) operates in the corresponding operation mode.

[0031] The processor (110) can obtain the first power consumption in the LPM, which is a power saving operation state. The first power consumption may differ in the target detailed items for predicting individual power consumption, but may be obtained through substantially the same operation as the operation for obtaining the total power consumption. The processor (110) can obtain the second power consumption in the normal operation state based on the first power consumption. The second power consumption may be obtained by reflecting the light sensor savings, motion analysis savings, or object analysis savings based on at least one of PWM (pulse width modulation), ANA, dimming block, or current index according to a dimming method for controlling the operation of the display (150) in the first power consumption. The dimming method may include a local dimming method or a pulse width modulation (PWM) dimming method. The above local dimming method can improve contrast ratio and / or power consumption by dividing the screen of the display device (100) into multiple areas and lowering the brightness of areas corresponding to dark areas of the image or raising the brightness of areas corresponding to bright areas of the image. The above PWM dimming method can increase or decrease the screen brightness (e.g., luminance) of the display device (100) by controlling the pulse width.

[0032] The above-mentioned light sensor savings, motion analysis savings, or object analysis savings may be targets of power savings in the LPM, which is the power saving operation state. The processor (110) may determine the power consumption amount corresponding to the difference between the first power consumption amount and the second power consumption amount as the power saving amount.

[0033] The processor (110) may calculate an instantaneous power consumption based on the total power consumption acquired in response to the operating mode. The instantaneous power consumption may be a power consumption predicted for each power consumption measurement integration period (e.g., 10 seconds). For example, the instantaneous power consumption may be calculated by 'total power consumption * integration period / 3600'.

[0034] The communication circuit (120) may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between the display device (100) and an external electronic device (e.g., electronic devices (103, 104), or server (105)), and the performance of communication through the established communication channel. The communication circuit (120) may support direct (e.g., wired) communication or wireless communication in response to the control of the CP (114). The communication circuit (120) may include a wireless communication module (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (e.g., a local area network (LAN) communication module, or a power line communication module). Among the above communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (101) (e.g., a short-range communication network such as Bluetooth, WiFi (wireless fidelity) direct, or IrDA (infrared data association)) or a second network (102) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as a plurality of separate components (e.g., multiple chips).

[0035] The sensor (130) can detect the operating status (e.g., power or temperature) of the display device (100) or the external environmental status (e.g., user status) and generate an electrical signal or data value corresponding to the detected status. The sensor (130) can include, for example, a gesture sensor, a gyro sensor, a pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an IR (infrared) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.

[0036] The speaker (140) can output an audio signal to the outside of the display device (100). The speaker (140) can be used for general purposes such as multimedia playback or recording playback. The volume of the speaker (140) can increase or decrease in response to the control of the audio controller (116). The power consumption of the speaker (140) can vary depending on the volume output. For example, the power consumption of the speaker (140) can increase as the volume increases, and can decrease as the volume decreases.

[0037] The display (150) can visually provide information to an external party (e.g., a user) of the display device (100). The display (150) may include, for example, a display, a holographic device, or a projector and a control circuit for controlling the device. The display (150) may include a touch sensor configured to detect a touch, or a pressure sensor configured to measure the strength of a force generated by the touch.

[0038] The above memory (160) can store various data used by at least one component (e.g., processor (110) or sensor (130)) of the display device (100). The data may include, for example, input data or output data for software (e.g., program) and / or commands related thereto. The memory (160) may include volatile memory (161) or nonvolatile memory (162).

[0039] The display device (100) may further include an interface or a connection terminal. The interface may support one or more designated protocols that may be used to directly or wirelessly connect the display device (100) with an external electronic device (e.g., the electronic device (103)). The interface may include, for example, a high definition multimedia interface (HDMI), a universal serial bus (USB) interface, an SD card interface, or an audio interface. The connection terminal may include a connector through which the display device (100) may be physically connected with an external electronic device (e.g., the electronic device (103)). The connection terminal may include, for example, an HDMI connector, a USB connector, an SD card connector, or an audio connector (e.g., a headphone connector).

[0040] FIG. 2 is a state transition diagram of a display device (e.g., the display device (100) of FIG. 1) according to one embodiment of the present disclosure.

[0041] Referring to FIG. 2, the display device (100) may include a standby state (WAIT STATE) (210) or an active state (ACTIVE STATE) (220) as an operating state. The display device (100) may operate in two modes in the standby state (210). For example, the display device (100) may operate in one of a sleep state (SLEEP STATE) or an idle state (IDLE STATE) depending on the ease of state transition from the standby state (210) to the active state (220). The display device (100) may operate in two modes in the active state (220). For example, the display device (100) may operate in one of a normal operating state (2210) or a power saving operating state (2220) depending on whether power consumption is reduced in the active state (220). The above power saving operation state (2220) may be a state in which the display device (100) operates with relatively lower power consumption compared to the normal operation state (2210). Accordingly, the display device (100) may reduce power consumption in the power saving operation state (2220) compared to the normal operation state (2210).

[0042] The display device (100) may transition to the activated state (220) when an activation event occurs in the standby state (210) (operation 211). The activation event may correspond to a screen output request occurring by the display device (100). The display device (100) may transition from the standby state (210) to the normal operation state (2210) which is the activated state (220). The display device (100) may transition to the standby state (210) when a deactivation event occurs in the activated state (220) (operation 211). The deactivation event may occur when no other event occurs for a certain period of time after the screen output by the display device (100) is stopped. The above display device (100) can transition from the power saving operation state (2220) which is the activated state (220) to the standby state (210).

[0043] The display device (100) may consume power when operating in the normal operation state (2210). The display device (100) may monitor power consumption to obtain the power consumption (or energy consumption) (operation 2211). The display device (100) may obtain the power consumption, for example, by calculating or predicting the power consumption. The power consumption may be the amount of power consumed for a predetermined period of time due to the operation of the display device (100). The power consumption may include individual power consumption or total power consumption. The individual power consumption may be the power consumption calculated or predicted for each detailed operation item of the display device (100). The detailed operation items may include an operation for driving a backlight, an operation for obtaining an output image of a predetermined quality (e.g., resolution or APL), an operation for processing a video signal, or an operation for processing an audio signal. The above total power consumption can be obtained by accumulating one or more individual power consumption amounts among the individual power consumption amounts.

[0044] The display device (100) can calculate or predict individual power consumption for each detailed operation item. The display device (100) can calculate or predict, for example, light source power consumption as individual power consumption. The display device (100) can calculate or predict, for example, cell power consumption as individual power consumption. The display device (100) can calculate or predict, for example, video processing power consumption as individual power consumption. The display device (100) can calculate or predict, for example, audio processing power consumption as individual power consumption. Each of the individual power consumptions may be different depending on the operation mode of the display device (100). In the display device (100), the operation mode may include, for example, a basic mode, a picture-off mode, or an LPM. When the display device (100) operates in the picture-off mode compared to the basic mode, the power consumption (for example, at least one of the individual power consumptions) may be relatively reduced. The display device (100) may have a relatively reduced power consumption (e.g., at least one of the individual power consumptions) when operating in LPM compared to the picture-off mode.

[0073] The above-described <Mathematical Formula 1> to <Mathematical Formula 3> may be defined differently depending on the dimming type. For example, a constant that may vary depending on the number of pixels (e.g., 1023 in Mathematical Formula 1) may be changed depending on the dimming type (e.g., 4095).

[0074] The display device (100) can predict cell power consumption in operation 323. The cell power consumption may be the power consumption used for an operation to obtain an output image of a predetermined quality. The display device (100) can predict the cell power consumption by considering an APL value and / or resolution. The display device (100) can obtain the APL value and / or the resolution by analyzing image information of an image being output through the display (150).

[0075] For example, if the resolution of the image to be output is UHD or higher, the display device (100) consumes P, which is the power consumption per hour defined corresponding to the cell in the above . CELL The cell power consumption can be obtained by multiplying the high resolution by a weighting factor (e.g. 1.1).

The main board power consumption may be the video processing power consumption used for an operation to process a video signal. The display device (100) can predict the video processing power consumption by considering the resolution and / or the operation mode. The display device (100) can analyze the image information of the image being output through the display (150) to obtain the resolution and / or the operation mode. Since the main board of the display device (100) can determine the blocks to be driven according to the operation mode, the power consumption used in the main board may vary depending on the operation mode.

[0078] For example, if the resolution of the image to be output is UHD or higher, the display device (100) consumes P, which is the power consumption per hour defined corresponding to the main board in the above . MAIN The power consumption of the motherboard can be obtained by multiplying it by a weighting factor (e.g. 1.1) according to the high resolution.

SPEAKER SET is the volume level set above VOLUME Speaker power consumption (P) reflecting SPEAKER You can obtain (SET_VOLUME / 100)-1).

[0085] The display device (100) can predict power consumption for each operation scenario in operation 340. The display device (100) can calculate or predict total power consumption or instantaneous power consumption by comprehensively considering the image and backlight control information output for each operation scenario and the operation mode. The display device (100) can accumulate the light source power consumption, cell power consumption, video processing power consumption, or audio processing power consumption predicted for each operation scenario in operation 340 to obtain total power consumption or instantaneous power consumption corresponding to the corresponding operation mode.

[0086] The display device (100) can determine the total predicted power consumption in operation 350. The total power consumption can be obtained by accumulating one or more individual power consumption amounts among the individual power consumption amounts.

[0087] below shows an example in which the processor (110) predicts or calculates the total power consumption in each operation mode.

[0088] Operating ModeTotal Power Consumption (WH)Basic ModeP BLU +P CELL +P MAIN +P SPEAKER LPMP MAIN_LPM Background suspend modeP MAIN Always-on display display mode (always on screen / ambient mode)P BLU +P CELL +P MAIN Picture off modeP MAIN +P SPEAKER Suspend mode 0AI saving mode off P AI_OFF_BLU +P CELL +P MAIN +P SPEAKER

[0094] According to the above , since no module operates in the pause mode, the individual power consumption and total power consumption can be 0.

[0095] FIG. 4 is a flowchart illustrating an exemplary procedure performed to monitor the amount of power consumption reduction in a display device (e.g., the display device (100) of FIG. 1) according to one embodiment of the present disclosure.

[0096] Referring to FIG. 4, the display device (100) can identify a function that is activated before a power saving mode (e.g., a power saving operation state (2220) of FIG. 2) is executed in operation 410. For example, the display device (100) can determine whether a light sensor, content motion analysis, or content region of interest analysis function is activated in a normal operation state (e.g., a normal operation state (2210) of FIG. 2). This can be considered for selecting a target for reducing power consumption in the power saving operation state (2220).

[0097] The display device (100) can predict power consumption in power saving mode at operation 420. As described above, the display device (100) predicts individual power consumption for each module and obtains total power consumption based on the predicted power consumption. The display device (100) can predict power consumption by the same operation even in power saving mode. According to an example, the power consumed by the display device (100) may vary depending on a dimming method for adjusting the brightness. In the display device (100), a dimming method that blinks a light source such as a backlight based on image characteristics may be applied. The dimming method may include a local dimming method or a pulse width modulation (PWM) dimming method. The above local dimming method can improve contrast ratio and / or power consumption by dividing the screen of the display device (100) into multiple areas and lowering the brightness of areas corresponding to dark areas of the image or raising the brightness of areas corresponding to bright areas of the image. The above PWM dimming method can increase or decrease the screen brightness (e.g., luminance) of the display device (100) by controlling the pulse width.

[0098] The display device (100) may, in operation 430, predict a brightness setting value and an illuminance level in a power saving mode (e.g., a power saving operation state (2220) of FIG. 2). The brightness setting value predicted in the power saving mode may have a relatively lower value than in the normal operation state (2210). The illuminance level predicted in the power saving mode may have a relatively lower level than in the normal operation state (2210). If the illuminance level is low, an image with low illuminance may be output by the display device (100). As the brightness setting value is lowered, the amount of power consumption used for this may be reduced. As the illuminance level is lowered, the amount of power consumption used for this may be reduced. A decrease in the amount of power consumption may indicate an increase in the amount of power savings.

[0099] The display device (100), in operation 440, can determine or obtain the power consumption expected to be reduced in the power saving mode. For example, the display device (100) can calculate or predict the amount of power consumption to be additionally used when the power saving mode is activated based on the dimming power consumption, the brightness setting value, or the illuminance level. For example, the display device (100) can predict the amount of savings that can be obtained by reducing the power consumption of the illuminance sensor in order to predict the dimming power consumption. The display device (100) can predict the amount of savings that can be obtained by reducing the power consumed for motion analysis in order to predict the dimming power consumption. The display device (100) can predict the amount of savings that can be obtained by reducing the power consumed for object analysis in order to predict the dimming power consumption. The display device (100) can obtain the amount of savings for the dimming power consumption by synthesizing the predicted savings for each of the three items.

[0100] The display device (100) can obtain the power consumption in the normal operation mode (2210) at operation 450. For example, the display device (100) can obtain the power consumption in the normal operation mode (2210) by applying the power saving amount to the power consumption in the power saving mode.

[0101] The display device (100) can output the amount of power savings in operation 460. For example, the display device (100) can provide information about the amount of power savings to a user terminal such as a smartphone.

[0102] FIG. 5 is a timing diagram for measuring power consumption in a display device (e.g., display device (100) of FIG. 1) according to one embodiment of the present disclosure.

[0103] Referring to FIG. 5, the display device (100) can initiate monitoring of power consumption at a predetermined starting point (510). The predetermined point in time may be, for example, a point in time when the operating state of the display device (100) transitions from a standby state (e.g., the standby state (210) of FIG. 2) to an activated state (e.g., the activated state (220) of FIG. 2). The activated state may include a normal operating state (e.g., the normal operating state (2210) of FIG. 2) or a power saving operating state (e.g., the power saving operating state (2220) of FIG. 2).

[0104] The display device (100) can predict power consumption at a predetermined cycle (520), including cycles (521, 523, 525, 527, 529). The display device (100) can predict power consumption in response to the occurrence of a predetermined event. The predetermined event may include, for example, an event in which a user requests the amount of power currently being consumed. The predetermined event may include, for example, an event in which an operation mode or service of the display device (100) is changed. The operation mode may include a standby state (210) or an activated state (220). The activated state may include a normal operation state (2210) or a power saving operation state (2220). The change in the service may be, for example, a change in the type of content provided by the display device (100). For example, if a user requests playback of music content while watching video content through a display device (100), the display device (100) can recognize that a service change has occurred. The display device (100) can consider that a predetermined event has occurred only when a change in a service is predicted to result in a change in power consumption.

[0105] The display device (100) can predict individual power consumption corresponding to each of detailed operation items that generate power consumption in the operation mode for each cycle (521, 523, 525, 527, 529). The operation mode may be one of a basic mode, a picture-off mode, or an LPM. The detailed operation items may include an operation for driving a backlight, an operation for obtaining an output image of a predetermined quality, an operation for processing a video signal, or an operation for processing an audio signal. The individual power consumption may include, for example, a light source power consumption amount, a cell power consumption amount, a video processing power consumption amount, or an audio processing power consumption amount. The light source power consumption amount may be a power consumption amount used for an operation for driving a backlight. The light source power consumption amount may be predicted based on a pulse width according to ANA and PWM. The cell power consumption amount may be a power consumption amount used for an operation for obtaining an output image of a predetermined quality. The cell power consumption amount may be predicted in consideration of an APL value and / or a resolution. The above APL value and / or the resolution may be obtained by analyzing the image information of the image being output through the display of the display device (100) (e.g., the display (150) of FIG. 1). The video processing power consumption may be the power consumption used for an operation to process a video signal. The video processing power consumption may be predicted in consideration of the resolution and / or the usage scenario. The audio processing power consumption may be the power consumption used for an operation to process an audio signal. The audio processing power consumption may be predicted based on the output volume of the speaker (140).

[0106] The display device (100) may consider a driving current specification defining a usage range of a preset driving current and a driving voltage specification defining a usage range of a preset driving voltage in order to predict the individual power consumption. The driving current specification may be determined in advance based on a driving current curve according to a material type of a panel used in the display (150) of the display device (100). The driving voltage specification may be determined in advance based on a driving voltage curve according to a material type of a panel used in the display (150) of the display device (100).

[0107] The above display device (100) can calculate the average of the predicted individual power consumption for each predetermined cycle (521, 523, 525, 527, 529) in response to the detailed operation items, and determine the average individual power consumption as the individual power consumption of the corresponding detailed operation item.

[0108] The display device (100) can obtain the total power consumption in the corresponding operation mode by accumulating the predicted individual power consumption for each detailed operation item at a predetermined end point (530). When accumulating the individual power consumption, the display device (100) can apply different gains to each detailed operation item. For example, the gain to be applied to the individual power consumption can be applied based on the error range that may occur when predicting the individual power consumption. In other words, the gain can be used for the purpose of correcting the error.

[0109] The display device (100) can obtain a first power consumption amount in a power saving operation state (2220). The first power consumption amount may differ in the target detailed items for predicting individual power consumption amounts, but may be obtained through substantially the same operation as the operation for obtaining the total power consumption amount described above. The display device (100) can obtain a second power consumption amount in a normal operation state (2210) based on the first power consumption amount. The second power consumption amount may be obtained by reflecting a light sensor saving amount, a motion analysis saving amount, or an object analysis saving amount based on at least one of a PWM, an ANA, a dimming block, or a current index according to a dimming method for controlling the operation of the display (150) to the first power consumption amount. The light sensor saving amount, the motion analysis saving amount, or the object analysis saving amount may be objects of power saving in the power saving operation state (2220).

[0110] The above display device (100) can determine the power consumption amount corresponding to the difference between the first power consumption amount and the second power consumption amount as the power saving amount.

The information output through the display window (630a) may include the total energy consumption (633a) used in the home. The information output through the display window (630a) may include a graph (635a) showing the change (g1) in the energy consumption used by the display device (100) from the start of a cycle for monitoring energy consumption (e.g., monthly) to the present time and the change (g2) in the energy consumption predicted thereafter.
