The display device 100 according to an embodiment may include a display 110 and a stand 120 supporting the display 110.
In one example, the stand 120 includes a power circuit 121, and may receive external power via the power circuit 121. For example, the power circuit 121 may be wired to an outlet located on a wall, and may receive commercial power (hereinafter, referred to as external power).
According to an embodiment, the stand 120 may include a first battery 122. For example, the first battery 122 may be rechargeable by external power, and may output the charged power to provide power required to drive the display device 100 such as the display 110, i.e., driving power.

Here, the first battery 122 may include a rechargeable secondary cell or a fuel cell.
According to an embodiment, the display device 100 may be implemented as a mobile device without spatial constraints, such as having to be located adjacent to a wall outlet, since the display device 100 can be driven using the output power of the first battery 122 even if the power circuit 121 is not connected to a wall outlet by wire (i.e., even if external power is not received).
Referring to
First, the display 110 according to an embodiment may be implemented as various types of displays such as liquid crystal display (LCD), organic light-emitting diode (OLED), Liquid Crystal on Silicon (LCOS), Digital Light Processing (DLP), quantum dot (QD) display panel, quantum dot light-emitting diodes (QLED), Micro light-emitting diodes (μLED), Mini LED, etc.

Here, the power circuit 121 is implemented as a switched mode power supply (SMPS), and may include a power factor correction circuit, i.e., a PFC circuit, to meet the driving power of the display device 100 and various regulations.
According to an embodiment, the power circuit 121 may convert external power, i.e., alternating current power, into direct current power to reliably supply the power to an internal load of the display device 100 (e.g., a board including the display 110, a first battery 122 included in the stand 120, the one or more processors 130, etc.).
The one or more processors 130 according to an embodiment may control the overall operations of the display device 100.
According to an embodiment, the processor 130 may be implemented as a digital signal processor (DSP) for processing digital signals, a microprocessor, or a time controller (TCON). However, the processor 130 is not limited thereto, and the processor 130 may include one or more of a central processing unit (CPU), a micro controller unit (MCU), a micro processing unit (MPU), a controller, an application processor (AP), a communication processor (CP), an ARM processor, and an Artificial Intelligence (AI) processor, or may be defined as the corresponding term. Further, the processor 130 may be implemented as a system on chip (SoC) with embedded processing algorithms, a large scale integration (LSI), or in the form of a field programmable gate array (FPGA). The processor 130 may perform various functions by executing computer executable instructions stored in the memory.
The one or more processors 130 may include one or more of a central processing unit (CPU), a graphics processing unit (GPU), an accelerated processing unit (APU), a many integrated core (MIC), a digital signal processor (DSP), a neural processing unit (NPU), a hardware accelerator, or a machine learning accelerator. The one or more processors 130 may control one or any combination of the other components of the electronic apparatus, and may perform communication-related operations or data processing. The one or more processors 130 may execute one or more programs or instructions stored in the memory. For example, the one or more processors 130 may perform a method according to an embodiment by executing one or more instructions stored in the memory.
When a method according to an embodiment includes a plurality of operations, the plurality of operations may be performed by one processor or by a plurality of processors. For example, when a first operation, a second operation, and a third operation are performed by the method according to an embodiment, all of the first operation, the second operation, and the third operation may be performed by the first processor, or the first operation and the second operation may be performed by the first processor (e.g., a general-purpose processor) and the third operation may be performed by the second processor (e.g., an artificial intelligence-dedicated processor).
The one or more processors 130 may be implemented as a single core processor including a single core, or as one or more multicore processors including a plurality of cores (e.g., homogeneous multicore or heterogeneous multicore). When the one or more processors 130 are implemented as a multicore processor, each of the plurality of cores included in the multicore processor may include internal memory of the processor, such as cache memory and an on-chip memory, and a common cache shared by the plurality of cores may be included in the multicore processor. Each of the plurality of cores (or some of the plurality of cores) included in the multi-core processor may independently read and perform program instructions to implement the method according to an embodiment, or all (or some) of the plurality of cores may be coupled to read and perform program instructions to implement the method according to an embodiment
When a method according to an embodiment includes a plurality of operations, the plurality of operations may be performed by one core of a plurality of cores included in a multi-core processor, or may be performed by a plurality of cores. For example, when a first operation, a second operation, and a third operation are performed by a method according to an embodiment, all of the first operation, the second operation, and the third operation may be performed by the first core included in the multi-core processor, or the first operation and the second operation may be performed by the first core included in the multi-core processor and the third operation may be performed by the second core included in the multi-core processor.
In the embodiments of the present disclosure, the processor may mean a system-on-chip (SoC) in which at least one processor and other electronic components are integrated, a single-core processor, a multi-core processor, or a core included in a single-core processor or multi-core processor, and here, the core may be implemented as CPU, GPU, APU, MIC, DSP, NPU, hardware accelerator, or machine learning accelerator, etc., but the core is not limited to the embodiments of the present disclosure.
In particular, the one or more processors 130 according to an embodiment may drive the display device 100 using external power received by the power circuit 121. For example, the one or more processors 130 may drive the display 110 using external power, and may control a charging and discharging circuit 123 included in the stand 120 to charge the first battery 122 included in the stand 120.
For example, the one or more processors 130 may provide a portion of the external power to the display 110 as first driving power to drive a plurality of LED elements included in the display 110, and the display 110 may light the plurality of LED elements using the first driving power. Further, the one or more processors 130 may provide the remainder of the external power received by the power circuit 121 to the first battery 122 as charging power, which will be described in greater detail with reference to
Referring to
According to an embodiment, the power circuit 121 may provide power to each of the display 110, the charging and discharging circuit 123, and the one or more processors 130.
According to an embodiment, when a user command to turn the display 110 on is received, the one or more processors 130 may control the power circuit 121 to provide the display with a portion of the external power received by the power circuit 121 as first driving power.
Further, the one or more processors 130 may control the power circuit 121 and the charging and discharging circuit 123 to provide the remainder of the external power received by the power circuit 121 to the first battery 122 as charging power.
This will be explained in greater detail with reference to
Referring to
Here, the specific numbers are only examples for convenience of explanation and are not limited thereto. For example, the one or more processors 130 may increase the ratio of the first driving power provided to the display 110 from the external power as the maximum output luminance of the display 110 increases (e.g., from 0.8 to 0.9, etc.)
Further, according to various embodiments, the feature of providing driving power to the display 110 includes the feature of providing power to various internal loads included in the display device 100 in addition to the display 110 for the overall operations of the display device 100, such as the display device 100 receiving an image signal and the display 110 outputting an image corresponding to the image signal.
The one or more processors 130 according to an embodiment may provide external power (e.g., 100 W) to the display 110 as first driving power, and may not provide charging power to the first battery 122. For example, when the image corresponding to the image signal is a high luminance image above a threshold output luminance, the one or more processors 130 may provide all of the external power to the display 110 as first driving power.
When a user command to turn off the display 110 is received, the one or more processors 130 according to an embodiment may control the charging and discharging circuit 123 to turn off the display 110 and provide external power (e.g., 60 W) to the first battery 122 as charging power.
For example, the one or more processors 130 may control the charging and discharging circuit 123 to provide charging power to the first battery 122 based on the maximum allowable power of the first battery 122 in the off state of the display 110.
According to an embodiment, the charging and discharging circuit 123 provides a constant current (CC) to the first battery 122 under control of the one or more processors 130, and when the internal voltage of the first battery 122 continuously rises and reaches a reference value, the charging and discharging circuit 123 may change the internal voltage of the first battery 122 to a constant voltage (CV) to prevent overvoltage, and continuously decrease the amount of current provided to the first battery 122 to complete charging of the first battery 122. However, the charging method for the first battery 122 of the charging and discharging circuit 123 is not limited to the CC/CV charging method described above, and it is of course possible to charge the first battery 122 using various charging methods.
The one or more processors 130 according to an embodiment may operate the display device 100 in the battery priority use mode. Here, the battery priority use mode may be a mode in which the first battery 122 is discharged to provide driving power to the display 110, regardless of whether the power circuit 121 receives external power.
Referring to
In one example, the one or more processors 130 may control the charging and discharging circuit 123 so that the first battery 122 prevents overcurrent and outputs a constant current (CC), and when the first battery 122 outputs a certain amount of power (i.e., discharges) and the internal voltage of the first battery 122 drops below a threshold voltage, the discharging can be completed.
When the size of the second driving power provided to the display 110 through the first battery 122 is relatively small compared to the size of the first driving power provided to the display 110 through the power circuit 121, the one or more processors 130 may adjust the maximum output luminance of the display 110. For example, the one or more processors 130 may lower the maximum output luminance of the display 110 according to the size of the second driving power provided to the display 110 through the first battery 122.
For example, when no external power is received while the one or more processors 130 provides a portion of the external power to the display 110 as first driving power and the remainder of the external power to the first battery 122 as charging power, the one or more processors 130 may automatically switch to the battery priority use mode. Subsequently, the one or more processors 130 may control the charging and discharging circuit 123 to discharge the first battery 122 to provide the power output by the first battery 122 to the display 110 as second driving power.
When the external power is not received suddenly, the direction of the current of the charging and discharging circuit 123 that is providing charging power to the first battery 122 cannot change instantaneously. In one example, the charging and discharging circuit 123 includes an inductor, and since the direction of the current flowing through the inductor (or the polarity of the inductor) cannot change instantaneously, the stand 120 may include a diode 124 connected in parallel to the charging and discharging circuit 123 to provide the power output by the first battery 122 to the display 110 as second driving power.
In one example, while the one or more processors are driving the display device 100 by providing a portion of the external power to the display 110 as first driving power, when the external power is suddenly not received (e.g., the power circuit 121 is disconnected from an outlet while connected to the outlet located on a wall via wire), the one or more processors 130 may provide a portion of the external power to the display 110 as first driving power to drive the display device 100, the one or more processors may automatically switch to the battery priority use mode and then, may provide the power output by the first battery 122 to the display 110 as second driving power for a threshold time.
Subsequently, the one or more processors 130 may provide the second driving power to the display 110 via the charging and discharging circuit 123 after the threshold time has elapsed.
Here, the size of the second driving power provided to the display 110 after the threshold time has elapsed may be relatively greater than the size of the second driving power provided to the display 110 during the threshold time.
When the power (e.g., 20 W) output by the first battery 122 for a threshold time, i.e., the second driving power, is less than the minimum driving power of the plurality of LED elements included in the display 110, the one or more processors 130 may adjust the output luminance of the display 110 to below the threshold luminance or turn off the plurality of LED elements for the threshold time
In one example, when the external power is suddenly not received, there is an effect that one or more processors 130 can continuously drive the display device 100 by adjusting the output luminance of the display 110 to below the threshold luminance for a threshold time, or even if the plurality of LED elements are turned off for the threshold time, by using the power output by the first battery 122 without re-booting the display device 100.
When no external power is received in the battery priority use mode, the one or more processors 130 may set a first output voltage (Vout_1) corresponding to the power circuit 121 to be greater than a second output voltage (Vout_2) corresponding to the charging and discharging circuit 123 (i.e., Vout_1>Vout_2) and thus, when the power circuit 121 receives the external power again (e.g., when the power circuit 121 is connected to an outlet via wire while not connected to the outlet located on the wall), the one or more processors 130 can automatically switch from the battery priority use mode to the normal mode to receive the external power from the power circuit 121 to provide the first driving power to the display 110 and the charging power to the first battery 122 via the charging and discharging circuit 123. Here, the normal mode may refer to a battery charging mode in which a portion of the external power is provided to the display 110 as the first driving power and the remainder is provided to the first battery 122 as charging power.
The display device 100 according to an embodiment may further include a smart shelf 140. In one example, the smart shelf 140 is removably attachable to the stand 120, and may include a main body 140-1 and a fixture 140-2. The shape of each of the main body 140-1 and fixture 140-2 of the smart shelf 140 illustrated in
Further, each of the main body 140-1 and the fixture 140-2 includes a magnetic material, and may be attachable to the stand 120 by combining the magnetic material included in the main body 140-1 and the magnetic material included in the fixture 140-2. However, this is only an example, and the smart shelf can be attached to and detached from the stand 120 in various ways. For example, each of the main body 140-1 and the fixture 140-2 includes a nut and a bolt, and can be attached to the stand 120 by fastening the bolt and the nut.
Here, the smart shelf 140 can be attached to the stand 120 horizontally to the floor on which the display device 100 is located. Although
According to an embodiment, the smart shelf 140 includes the communication interface 141, and may perform communication with an external device through the communication interface 141. The communication interface 141 according to an embodiment receives various signals and data. For example, the communication interface 141 may perform communication with an external device through various wired/wireless communication methods such as such as an access point (AP)-based wireless fidelity (Wi-Fi, wireless local area network (LAN) network, a Bluetooth, a Zigbee, a wired/wireless local area network (LAN), a wide area network (WAN), Ethernet, an IEEE 1394, a high definition multimedia interface (HDMI), a Universal Serial Bus (USB), a mobile high-definition link (MHL), audio engineering society/European broadcasting union (AES/EBU), optical, coaxial, near field communication (NFC) communication, etc. In addition, the communication interface 141 may be implemented as a wired communication interface, for example, V-by-One, High Definition Multimedia Interface (HDMI) cable, Low Voltage Differential Signals (LVDS) cable, Digital Visual Interface (DVI) cable, D-subminiature (D-SUB) cable, Video Graphics Array (VGA) cable, optical cable, etc.
In
Referring to
According to an embodiment, the connection 142 connects the internal load of the smart shelf 140 to the internal load of the display device 100, and may, for example, receive a control signal from the one or more processors 130 or receive power from the power circuit 121 or the first battery 122. In addition, the connection 142 may transmit an image signal received by the communication interface 141 from an external device to the one or more processors 130. The connection 142 may be implemented as a wired communication interface or a wireless communication interface according to various communication methods.
When the smart shelf 140 is attached to the stand, the one or more processors 130 according to an embodiment may provide first partial power (e.g., 70 W) from the external power (e.g., 100 W) received by the power circuit (121) to the display 110 as first driving power, second partial power (e.g., 20 W) to the first battery 122 as charging power, and third partial power to the smart shelf 140. The internal load (e.g., the communication interface 141, the connection 142) of the smart shelf 140 may be driven using the third partial power.
Before the smart shelf 140 is attached, the one or more processors 130 transmit the external power to each of the display 110 and the first battery 122, and after the smart shelf 140 is attached, the one or more processors 130 transmit the external power to the display 110, the first battery 122, and the smart shelf 140, so that the size of the first driving power provided to the display 110 after the smart shelf 140 is attached may be smaller than the size of the first driving power provided to the display 110 before the smart shelf 140 is attached (e.g., 80 W->70 W). In addition, the size of the charging power provided to the first battery 122 after the smart shelf 140 is attached may be smaller than the size of the charging power provided to the first battery 122 before the smart shelf 140 is attached (e.g., 20 W->10 W).
However, this is only an example, and the present disclosure is not limited thereto. For example, the one or more processors 130 may maintain the size of the first driving power provided to the display 110 before the smart shelf 140 is attached and the size of the first driving power provided to the display 110 after the smart shelf 140 is attached (e.g., 80 W->80 W) in order to maintain the output luminance of the display 110, obtain the third partial power (e.g., 10 W) by lowering the size of the charging power provided to the first battery 122 after the smart shelf 140 is attached compared to before the smart shelf 140 is attached (e.g., 20 W->10 W), and provide the third partial power as the driving power of the smart shelf 140.
In another example, the one or more processors 130 may maintain the size of the first driving power provided to the display 110 before the smart shelf 140 is attached and the size of the first driving power provided to the display 110 after the smart shelf 140 is attached (e.g., 80 W->80 W), and when the smart shelf 140 is attached, may not charge the first battery 122 (i.e., reduce the size of the charging power provided to the first battery 122 to 0 W) (e.g., 20 W->0 W), obtain the third partial power (e.g., 20 W), and provide the third partial power as the driving power for the smart shelf 140.
The smart shelf 140 according to an embodiment may include a battery unit 143. Here, the battery unit 143 may include a second battery 143-1 and a charging and discharging circuit 143-2. The operation of each of the second battery 143-1 and the charging and discharging circuit 143-2 may be the same as the operation of each of the first battery 122 and the charging and discharging circuit 123 included in the stand 120.
The one or more processors 130 according to an embodiment may control the charging and discharging circuit 143-2 to provide the third partial power from the external power s to the smart shelf 140, provide a portion of the third partial power to an internal load included in the smart shelf 140, and provide the remainder of the third partial power to the second battery 143-1 as charging power.
The one or more processors 130 according to an embodiment may separate the second partial power and the third partial power from the external power such that the first battery 122 is charged before the second battery 143-1.
For example, the one or more processors 130 may provide the remaining power to the first battery 122 as charging power except for the first driving power to provide to the display 110 from the external power and the power to provide to the internal load included in the smart shelf 140.
Subsequently, when the one or more processors 130 receive a feedback signal indicating completion of charging the first battery 122 from the charging and discharging circuit 123, the one or more processors 130 may re-separate the second partial power and the third partial power from the external power to charge the second battery 143-1.
For example, the one or more processors 130 may provide the remaining power, excluding the first driving power to provide to the display 110 from the external power, to the smart shelf 140 as the third partial power, and the smart shelf 140 may control the charging and discharging circuit 143-2 to provide a portion of the third partial power to an internal load included in the smart shelf 140 and provide the remainder of the third partial power to the second battery 143-1 as charging power. In this case, the second partial power to provide to the first battery 122 may be 0 W.
The smart shelf 140 further includes a power circuit, and the power circuit included in the smart shelf 140 is connected to an outlet located on a wall via wire, and may also receive commercial power (hereinafter, referred to as external power).
In one example, when the power circuit included in the smart shelf 140 receives external power, the one or more processors 130 may control the charging and discharging circuit 143-2 to provide a portion of the external power received by the power circuit included in the smart shelf 140 to an internal load included in the smart shelf 140 and provide the remainder to the second battery 143-1 as charging power.
In one example, when no external power is received, the one or more processors 130 may automatically switch to a battery priority use mode and discharge in the order of the first battery 122 to the second battery 143-1. For example, the one or more processors 130 may provide the power output by the first battery 122 to the display 110 as the second driving power, and when the discharging of the first battery 122 is completed, may provide the power output by the second battery 143-1 to the display 110 as the third driving power. However, this is only an example, and the present disclosure is not limited thereto. For example, the one or more processors 130 may discharge in the order of the second battery 143-1 to the first battery 122.
When a user command to turn off the display 110 is received, the one or more processors 130 according to an embodiment may control the charging and discharging circuit 123 to turn off the display 110 and provide a portion of the external power (e.g., 100 W) (i.e., the second partial power) to the first battery 122 as charging power.
In addition, the one or more processors 130 may control the charging and discharging circuit 143-2 included in the smart shelf 140 to provide the remainder of the external power (i.e., the third partial power) to the second battery 143-1 as charging power.
For example, the one or more processors 130 may control the charging and discharging circuit 123 to provide the charging power to the first battery 122 based on the maximum allowable power of the first battery 122 in the off state of the display 110, and control the charging and discharging circuit 143-2 to provide the charging power to the second battery 143-1 based on the maximum allowable power of the second battery 143-1 in the off state of the display 110.
The one or more processors 130 according to an embodiment may charge the first battery 122 and the second battery 143-1 simultaneously, and may control the charging and discharging circuit 123 included in the stand 120 and the first battery 122 and the second battery 143-1 to charge one of the first battery 122 and the second battery 143-1 first, and the other of the first battery 122 and the second battery 143-1 later.
