The power supply and communication harness of the display panel pass through the door hinges and are connected to the power supply of the control panel to realize the control of the display device and display the display function. On the one hand, due to the constraints of the product structure, the door hinges of some products are difficult to thread, and during normal use, the product opening and closing the door will bring the risk of disconnection.

On the other hand, when the light intensity in the environment does not reach above the preset light intensity, the energy storage unit is connected to the power supply circuit of the power supply module to provide power for the display device in insufficient light conditions, thereby ensuring that the display device can work normally.

[0018] In some embodiments, the power supply module includes a unidirectional conduction circuit, one end of the unidirectional conduction circuit is connected to the energy storage unit, and the other end is connected to the power supply circuit of the power supply module, and the controller is further configured to perform the following steps:

[0022] If a capacitance change of the unlock button is detected, the function button is controlled to be connected to the power supply circuit of the power supply module.

[0023] In the above embodiment, in order to avoid supplying power to all the buttons on the display device and causing continuous consumption of electric energy, in this embodiment, an unlock button is provided, so that after monitoring the change in the capacitance of the unlock button, the function buttons are controlled to be connected to the power supply circuit of the power supply module, thereby achieving the effect of low power consumption of the display device.

[0024] In some embodiments, the controller is further configured to perform the following steps:

[0025] If a communication task for the second communication module triggered by the function key is received, sending an enable signal to the second communication module so that the second communication module performs the communication task;

[0026] If the activation time of the second communication module reaches longer than the preset activation time and the communication task is not completed, the second communication module is controlled to enter a dormant state after the communication task is completed.

[0027] In the above embodiment, when a communication task for the second communication module triggered by a function button is received, a start signal is sent to the second communication module, so that the second communication module in the sleep state is awakened to perform the communication task normally, thereby ensuring low power consumption of the communication of the display device and ensuring communication efficiency. Moreover, when the start time of the second communication module reaches more than the preset start time, but the communication task on the communication module is not completed, the second communication module is controlled to enter the sleep state after the communication task is completed, thereby achieving low power consumption of the communication of the display device and ensuring the normal completion of the communication task without affecting the user experience.

[0028] In some embodiments, the controller is further configured to perform the following steps:

[0029] If the activation time of the second communication module exceeds the preset activation time, a time difference between the actual activation time of the second communication module and the preset activation time is calculated to adjust the preset sleep frequency of the second communication module based on the time difference.

[0030] In the above embodiment, if the on-time corresponding to the second communication module completing the communication task exceeds the preset on-time, the preset sleep frequency of the second communication module can be adjusted according to the time difference between the actual on-time of the second communication module and the preset on-time, thereby ensuring the low energy consumption of the display device while improving the intelligence of the display device and improving the user experience.

[0031] In some embodiments, the controller is further configured to perform the following steps:

[0034] In some embodiments, the controller is further configured to perform the following steps:

[0035] The display module is controlled to enter an on state according to a preset frequency; when the display module is in the on state, an on signal is sent to the second communication module to update the display content on the display module based on the communication data on the second communication module.

[0036] In the above embodiment, the display screen is controlled to enter an on state according to a preset frequency. When the display screen is in the on state, an on signal is sent to the second communication module to update the display content on the display module based on the communication data on the second communication module. This ensures that the display module of the display device is in low power consumption while also ensuring the accuracy of the display content on the display module in the on state.

[0037] In some embodiments, the controller is further configured to perform the following steps:

[0038] If the on time of the display module reaches longer than the preset on time and no display operation for the display module is received, the display module is controlled to enter a dormant state.

[0039] In the above embodiment, when the display module is turned on for a preset time period exceeding the preset time period and no display operation on the display module triggered by a key function is received, the display module is controlled to enter a sleep state, thereby achieving a low power consumption effect of the display module, and further achieving a low power consumption effect of the entire display device.

[0040] In some embodiments, the refrigerator further comprises a sensing module, wherein the sensing module is configured to:

[0041] If the target object is sensed, an opening signal is sent to the second communication module, and a communication connection is established between the first communication module and the second communication module;

[0042] If the target object is not sensed, a sleep signal is sent to the second communication module, and the communication connection between the first communication module and the second communication module is disconnected.

[0043] In the above embodiment, by setting a sensing module in the refrigerator, on the one hand, when the target object is sensed to be close to the refrigerator, the second communication module in the display device is awakened and a communication connection is established between the first communication module and the second communication module, thereby shortening the time for the display device to respond to user operations and improving the user experience. On the other hand, when the target object is not sensed, the second communication module is promptly controlled to enter a sleep state, thereby achieving the effect of low power consumption and communication of the display device.

[0054] In order to make the purpose and implementation method of the present application clearer, the exemplary implementation method of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0055] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0056] The terms "first", "second", "third", etc. in the specification and claims of this application and the above drawings are used to distinguish similar or similar objects or entities, and do not necessarily mean to limit a specific order or sequence, unless otherwise noted. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances.

[0057] The terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to all the components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0058] First of all, it should be noted that with the development of the home appliance industry, people's requirements for quality of life are getting higher and higher. More and more home appliances are equipped with corresponding operation and display panels. For example, common refrigerators, freezers, and wine cabinets generally place their operation and display panels on the door body. The power supply and communication harness of the display panel pass through the door hinges to connect to the power supply of the control panel to achieve control and display functions. However, due to the constraints of product structure, the door hinges of some products are difficult to thread, and in normal use, opening and closing the door will bring the risk of disconnection, and the requirements for door hinges are also relatively high. On the other hand, with the advancement of global low-carbon energy-saving requirements, the energy-saving level requirements for home appliances are also getting higher and higher.

[0059] In order to solve the above technical problems, a refrigerator provided with a display device that can be powered by its own power supply module and meets low power consumption is provided in an embodiment of the present application. Thus, the display device is powered by the power supply module of the display device itself, and there is no need for the power supply inside the refrigerator body to power it, thus avoiding the power supply line of the display module passing through the door hinge to connect to the power supply inside the refrigerator, thus avoiding the structural limitation of the door hinge. Moreover, on the other hand, the second communication module in the display device is controlled to enter a dormant state according to a preset frequency, and when the second communication module is turned on for a period of time exceeding the preset turn-on period and the communication task on the communication module has been completed, the second communication module is controlled to enter a dormant state, thereby realizing low-power communication of the display device and achieving the effect of energy saving and emission reduction.

[0060] See also Figure 1 , Figure 1 is a schematic diagram of a refrigerator with a low power consumption display device shown in an exemplary embodiment of the present application. Figure 1As shown, the refrigerator includes a box body, and a first communication module is arranged on the box body, and a display device is arranged on the door body of the box body. In some executable embodiments, the display device includes a power supply module, a display module, a power supply switch circuit, a second communication module and a controller, wherein the power supply switch circuit is used to connect the display module to the power supply circuit of the power supply module if a power supply start signal is detected, so as to realize the point connection between the power supply circuit and the display module, and the second communication module is used to receive the communication data sent by the first communication module in the refrigerator box if the start sequence is received, and update the display content on the display module based on the received communication data. Further, the controller is connected to the display module and the second communication module respectively to control the display module and the second communication module to enter a dormant state according to a preset frequency.

[0061] Specifically, Figure 2 As shown, the display device includes a power supply module and an unlocking button connected to the power supply module, so that the function buttons on the display device can be connected to the power supply module through the unlocking button, and a power supply switching circuit is provided in the display device to control the power supply in the power supply module to be connected to the subsequent circuit through the power supply switching circuit. Specifically, the subsequent circuit includes a display device, a controller and a second communication module, wherein the display device can use the communication data in the second communication module as the display content on the display device, and can also refresh the display content based on the communication data in the second communication module.

[0062] in, Figure 1 and Figure 2 The partial components of the display device on the refrigerator and the refrigerator door and the locations of these components are only shown by way of example. The specific composition of the display device and how to generate the display are prior arts and will not be elaborated in this application.

[0063] The implementation methods of the present application are further elaborated below in conjunction with the accompanying drawings in the embodiments of this specification.

[0064] The controller is specifically installed on a circuit board in the housing of the display device or the device on which the display device is installed, and is configured with a display device control circuit composed of electronic components such as a memory. The controller executes a control method stored in the memory to wake up the display device or control the display device to enter a dormant state. Specifically, the controller is configured to execute the following steps S210 to S230, which are described in detail as follows:

[0065] Step S210: controlling the second communication module to enter a sleep state according to a preset sleep frequency.

[0066] Specifically, in order to reduce the power consumption of the second communication module in the display device, the second communication module in the display device is controlled to enter a dormant state according to a preset dormancy frequency without affecting the normal operation of the display device. Exemplarily, if the second communication module is a Bluetooth communication circuit, the operating frequency of the Bluetooth communication circuit within a set time can be set. For example, the operating time of the Bluetooth communication circuit is 100ms, the cycle is 1 second, and the operation is repeated. If the set time is 30 seconds, each Bluetooth communication will repeat the operation 30 times.

[0067] In some feasible embodiments, in order to reduce the power consumption of the display device, the second communication module in the display screen can be controlled to enter a sleep state according to a preset sleep frequency. For example, the second communication module can be controlled to sleep for a period of time after being turned on for a period of time, or the second communication module can be turned on at a scheduled time to communicate and interact with the first communication module in the refrigerator body during the time period when the second communication module is turned on, so as to obtain relevant communication data to refresh the display content on the display device.

[0068] Step S220: If a start instruction of the second communication module is received when the second communication module is in the sleep state, a start signal is sent to the second communication module so that the second communication module receives the communication data sent by the first communication module.

[0069] Specifically, following the above-mentioned embodiment, in order to reduce the energy consumption of the display device, the second communication module will be controlled to enter the sleep state according to the preset sleep frequency. If the second communication module of the display device is in the sleep state and a start instruction of the second communication module is received, a start signal is sent to the second communication module, so that after the second communication module is turned on, the communication data sent by the first communication module in the refrigerator body can be received based on the second communication module.

[0070] Exemplarily, when the second communication module is in the dormant state, if the user triggers a communication task based on the button on the display screen, for example, to query the temperature information of the current refrigerator body's refrigeration layer, since the temperature information of the refrigerator body's refrigeration layer needs to be collected by the temperature collection module inside the refrigerator body and sent to the second communication module in the display device together with the first communication module inside the refrigerator body, then when the query of the temperature information of the current refrigerator body's refrigeration layer is triggered, an opening instruction of the second communication module is generated, and a second communication module opening signal is generated based on the opening instruction of the second communication module and sent to the second communication module to activate the second communication module in the display device, so as to interact with the first communication module in the refrigerator body through the second communication module to obtain the temperature information of the current refrigerator body's refrigeration layer, and update the temperature information of the current refrigerator body's refrigeration layer on the display module of the display device.

[0071] Step S230: If the activation time of the second communication module reaches a preset activation time or longer and the communication task on the second communication module has been completed, the second communication module is controlled to enter a dormant state.

[0072] Specifically, if it is detected that the on-time of the second communication module in the display device has reached a preset on-time and the communication task on the second communication module has been completed and there is no communication task being executed, in order to reduce the power consumption of the second communication module, the second communication module can be controlled to enter a sleep state, wherein the sleep state of the second communication module can include that all high-voltage components in the second communication module are discharged and enter a low power consumption state.

[0073] Exemplarily, in order to reduce the power consumption of the display device, the maximum on time of the second communication module is preset. That is to say, when it is detected that the on time of the second communication module has reached the preset maximum on time of the second communication module, and there is no communication task being executed on the second communication module, and the first communication module in the refrigerator body has no communication data being sent to the second communication module, the second module can be controlled to enter a sleep state.

[0074] In this embodiment, on the one hand, a display device is provided on the door of the refrigerator, and the display device includes a power supply module and a display module, so that the display module is connected to the power supply circuit of the power supply module through the power supply switch circuit, so as to realize the control of the power supply of the display module, and a second communication module is provided in the display device, and when the second communication module is turned on, communication data is obtained from the first communication module in the refrigerator box, so as to update the display content on the display module according to the obtained communication data, so as to realize the power supply of the display device itself, and no power supply in the refrigerator is required to supply it, so that the mechanism of the refrigerator door is not restricted by the display device, and the risk of disconnection caused by the door switch is avoided. On the other hand, a second communication module is provided in the display device, so that when the second communication module is turned on, the communication data sent by the first communication module in the refrigerator box is received, and then the display content of the display device is updated based on the communication data, and the second communication module is controlled to enter a dormant state according to a preset frequency, and when the second communication module is turned on for more than the preset time, and the communication task on the communication module is completed, the second communication module is controlled to enter a dormant state, so as to realize low-power communication of the display device and achieve the effect of energy saving and emission reduction.

[0075] Further, based on the above embodiment, please refer to Figure 3 In one of the exemplary embodiments provided in the present application, the power supply module includes a solar panel and an energy storage unit, and the controller is further configured to perform the following steps S310 and S320, which are described in detail as follows:

[0076] Step S310, if the light intensity in the current environment reaches or exceeds the preset light intensity, control the solar panel to access the power supply circuit of the power supply module;

[0077] Step S320: If the light intensity in the current environment does not reach or exceed the preset light intensity, the energy storage unit is controlled to be connected to the power supply circuit of the power supply module.

[0078] Specifically, Figure 3 As shown, in the present embodiment, in order to realize that the display device does not need to be powered by the power supply in the refrigerator body, but is powered by the power supply module carried by itself, a solar panel and an energy storage unit are arranged in the power supply module of the display device. Since the refrigerator is generally placed indoors or in a certain shielded area, when the light intensity of the environment in which the refrigerator is located reaches above the preset light intensity, the solar panel can generate electricity according to the light in the current environment, that is, the solar panel can be connected to the power supply circuit of the power supply module as the power supply of the display device, so that the electric energy generated by the solar panel can be supplied to the subsequent circuits, for example, the button module, the display module and the second communication module to provide working power.

[0079] In addition, following the above-mentioned embodiment, since the refrigerator is generally placed indoors or in a certain shaded area, if the light intensity in the environment where the refrigerator is located is lower than the preset light intensity, for example, at night when the light is weak, the electric energy generated by the solar panel is insufficient to support the power supply demand of the subsequent circuit of the display device. In this case, the energy storage unit in the power supply module can be connected to the power supply circuit to power the subsequent circuit of the display device through the energy storage unit. The energy storage unit is a battery that can be repeatedly charged and stored, and the amount of electricity in the energy storage unit is sufficient to support the power demand of the subsequent circuit of the display device.

[0080] In some feasible embodiments, by setting the time period corresponding to the power supply circuit of the solar panel connected to the power supply module and the time period corresponding to the power supply circuit of the energy storage unit connected to the power supply module, for example, the time period when the light intensity of the environment in which the refrigerator is located can reach the energy storage of the solar panel can be set as the time period corresponding to the power supply circuit of the solar panel connected to the power supply module, and the time period when the light intensity of the environment in which the refrigerator is located is not enough for the solar panel to store energy can be set as the time period corresponding to the power supply circuit of the energy storage unit connected to the power supply module. Thus, a corresponding clock module can be set in the actual device to control the power supply unit (solar panel or energy storage unit) corresponding to the power supply circuit connected to the power supply module through the clock module.

[0081] In this embodiment, a solar panel and an energy storage unit are arranged in the power supply module of the display device, so that when the light intensity in the environment reaches above the preset light intensity, the solar panel is controlled to be connected to the power supply circuit of the power supply module, and the solar panel provides power for normal use of the display device, thereby realizing the use of energy-saving solar panels in indoor scenes. On the other hand, when the light intensity in the environment does not reach above the preset light intensity, the energy storage unit is connected to the power supply circuit of the power supply module to provide power for the display device in insufficient light conditions, thereby ensuring that the display device can operate normally.

[0082] Further, based on the above embodiment, please refer to Figure 4a In one of the exemplary embodiments provided in the present application, the power supply module includes a unidirectional conduction circuit, one end of the unidirectional conduction circuit is connected to the energy storage unit, and the other end is connected to the power supply circuit of the power supply module, and the controller is further configured to perform the following steps:

[0083] If the voltage output by the solar panel exceeds the voltage output by the energy storage unit, the solar panel is controlled to be connected to the power supply circuit of the power supply module, and the output voltage of the solar panel cannot flow back into the energy storage unit through a unidirectional conduction circuit.

[0084] Specifically, a unidirectional conduction circuit is further provided in the power supply module of the display device, wherein the unidirectional conduction circuit includes a unidirectional conduction unit. In this embodiment, Figure 4b As shown, the unidirectional conduction unit can be a diode, wherein the output end of the diode is connected to the output end of the energy storage unit, and the output end of the diode is connected to the power supply circuit. When the controller detects that the voltage output by the solar panel in the power supply module is greater than the voltage output by the energy storage unit, the solar panel is connected to the power supply circuit of the power supply module to supply power to the subsequent circuit of the display device through the solar panel. However, in order to prevent the current in the power supply circuit from flowing to the energy storage unit, resulting in frequent charging of the energy storage unit, the output end of the diode can be used to resist the current output by the solar panel in the power supply circuit from flowing back into the energy storage unit.

[0085] In this embodiment, a unidirectional conduction circuit is provided in the power supply module, and the energy storage unit and the power supply circuit in the power supply module are connected through the unidirectional conduction circuit, so that when the voltage output by the solar panel exceeds the voltage output by the energy storage unit, the solar panel is controlled to be connected to the power supply circuit of the power supply module, so that the current output by the solar panel through the unidirectional conduction circuit cannot flow back into the energy storage unit, thereby avoiding frequent charging of the energy storage unit, which affects the life of the energy storage unit.

[0086] Further, based on the above embodiment, in one of the exemplary embodiments provided in the present application, the above display device further includes a key unit, the key unit includes an unlock key and a function key, the unlock key is connected to the power supply module, and the controller is further configured to perform the following steps, which are described in detail as follows:

[0087] If a capacitance change of the unlock button is detected, the control function button is connected to the power supply circuit of the power supply module.

[0088] Specifically, the operating buttons of refrigerator products generally use capacitive touch buttons, which require continuous power supply to the buttons. When a person operates the buttons, the capacitance of the buttons will change, and this capacitance change is used to determine whether a button operation has been performed. When there are multiple buttons, the power consumption will increase accordingly, and it is consumed continuously. In order to reduce this continuous power consumption, in this embodiment, a power supply switch circuit is added to the display device. Only after the unlock button is operated, that is, after the capacitance change of the unlock button is detected, the power supply circuits of other function buttons are controlled to be turned on, and the other function buttons can start to enter the working state. Figure 5 As shown, a key unit is included in the back-end circuit of the display device, and the key unit includes an unlocking key and a function key, wherein the unlocking key and the function key are connected in series, and one end of the unlocking key is connected to the power supply circuit of the power supply module. That is to say, under normal circumstances, the power supply circuit of the display device only needs to continuously supply power to the unlocking key, but does not need to continuously supply power to the function key, thereby reducing the power consumption of the display device.

[0089] In this embodiment, in order to avoid supplying power to all buttons on the display device, resulting in continuous consumption of electric energy, an unlock button is provided in this embodiment, so that after monitoring the change in the capacitance of the unlock button, the function buttons are controlled to be connected to the power supply circuit of the power supply module, thereby achieving the low consumption effect of the display device.

[0090] Further, based on the above embodiment, in one of the exemplary embodiments provided in the present application, the above controller is further configured to perform the following steps, which are described in detail as follows:

[0091] If a communication task for the second communication module triggered by a function key is received, an opening signal is sent to the second communication module to enable the second communication module to perform the communication task.

[0092] Specifically, in the present embodiment, the second communication module in the display device is generally in a dormant state, and the user can trigger a corresponding communication task based on the function button on the display device to wake up the second communication module in the display device, and send the communication task for the second communication module triggered by the function button to the second communication module, so that the second communication module sends a data request to the first communication module in the refrigerator body, thereby obtaining communication data corresponding to the communication task.

[0093] Exemplarily, in some achievable embodiments, the display module and the second communication module of the display device are both in a dormant state, and the user can wake up the display module and the second communication module in a dormant state through the function button set on the display device. For example, when the user adjusts the temperature in the refrigerator through the temperature adjustment button on the display module, the second communication module of the display device is woken up to obtain the temperature information in the refrigerator box at the current moment from the first communication module in the refrigerator box through the second communication module, and the temperature information is displayed on the display module. When the user adjusts the temperature in the refrigerator through the temperature adjustment button, the target temperature value adjusted by the user is displayed in real time on the display module. In addition, according to the target temperature value adjusted by the user, the user can be prompted not to adjust the temperature too low or too high to avoid affecting the service life of the refrigerator.

[0094] In this embodiment, when a communication task for the second communication module triggered by a function key is received, an on signal is sent to the second communication module, so that the second communication module in the sleep state is awakened to perform the communication task normally, thereby ensuring low power consumption of the display device communication and ensuring communication efficiency.

[0095] Further, based on the above embodiment, in one of the exemplary embodiments provided in the present application, the above controller is further configured to perform the following steps, which are described in detail as follows:

[0096] If the activation time of the second communication module reaches longer than the preset activation time and the communication task is not completed, the second communication module is controlled to enter a dormant state after the communication task is completed.

[0097] Specifically, following the above-mentioned embodiment, the second communication module in the display device is controlled to enter a sleep state according to a preset sleep frequency, that is, if the activation time of the second communication module reaches more than the preset activation time, the second communication module needs to be controlled to enter a sleep state. However, in actual application, if the communication task on the second communication module has not been completed, so as not to affect the user's experience, you can wait until the communication task on the second communication module is completed, and then control the second communication module to enter a sleep state, thereby reducing the power consumption of the display device while ensuring that the user's experience is not affected.

[0098] In this embodiment, when the on time of the second communication module reaches more than the preset on time, but the communication task on the communication module is not completed, the second communication module is controlled to enter the sleep state after the communication task is completed, thereby achieving low power consumption of the display device communication and ensuring the normal completion of the communication task.

[0099] Further, based on the above embodiment, in one of the exemplary embodiments provided in the present application, the above controller is further configured to perform the following steps, which are described in detail as follows:

[0100] If the activation time of the second communication module exceeds the preset activation time, a time difference between the actual activation time of the second communication module and the preset activation time is calculated to adjust the preset sleep frequency of the second communication module based on the time difference.

[0101] Specifically, following the above-mentioned embodiment, in order to successfully complete the communication task on the second communication module, after the opening duration of the second communication module reaches the preset opening duration, the second communication module is not controlled to enter the dormant state. However, in this case, if the preset dormancy frequency of the second communication module is not corrected, the dormancy duration of the second communication module will be insufficient, and the effect of low-power communication of the display device cannot be achieved. In some achievable embodiments, the time difference between the actual opening duration of the second communication module and the preset start duration of the second module is calculated to adjust the preset dormancy frequency of the second communication module based on the time difference. Among them, adjusting the preset dormancy frequency of the second communication module based on the time difference between the actual opening duration of the second communication module and the preset opening duration includes, on the one hand, while keeping the preset dormancy frequency of the second communication module unchanged, the next wake-up time point of the second communication module is postponed based on the time difference between the actual opening duration of the second module and the preset start duration. For example, the time difference between the actual opening duration of the second communication module and the preset opening duration of the second communication module is 30ms, then the next wake-up time point of the second communication module is postponed by 30ms. On the other hand, the preset on time of the second communication module in the preset sleep frequency of the second communication module can be corrected based on the actual on time of the second communication module. For example, if the actual on time of the second communication module is 40ms, the preset on time of the second communication module in the preset sleep frequency of the second communication module is set to 40ms, wherein the preset sleep time of the second communication module in the preset sleep frequency can be changed based on the change of the preset on time or remain unchanged, and the embodiments of the present application do not impose any limitations on this.

[0102] In this embodiment, if the on-time corresponding to the second communication module completing the communication task exceeds the preset on-time, the preset sleep frequency of the second communication module can be adjusted according to the time difference between the actual on-time of the second communication module and the preset on-time, thereby ensuring the low energy consumption of the display device while improving the intelligence of the display device and improving the user experience.

[0103] Further, based on the above embodiment, in one of the exemplary embodiments provided in the present application, the above controller is further configured to perform the following steps, which are described in detail as follows:

[0104] If a display operation for the display module triggered by a function key is received, a communication request is sent to the second communication module based on the display operation, so as to obtain display content corresponding to the display operation from the first communication module through the second communication module.

[0105] For details, please refer to Figure 5 In some feasible embodiments, the user connects the function key to the power supply module of the display device by triggering the unlock button on the display device. Then, the user can use the function key to trigger the display operation for the display module. Generally, the display operation requires refreshing the display content on the display module, and the refreshing of the display content needs to be based on the communication data received on the second communication module. Therefore, in this embodiment, if the display operation for the display device is received based on the function key triggered by the user, a corresponding communication request can be sent to the communication module according to the display data required for the display operation. If the second communication module is in a dormant state at the current moment, the second communication module in the dormant state can be awakened, and then the second communication module sends the relevant data required for the display content on the display module to the first communication module in the refrigerator body, and the first communication module obtains the data corresponding to the display operation from the control module in the refrigerator body or from the cloud server corresponding to the refrigerator, and forwards the data back to the second communication module in the display device, so that the display device can update the display content based on the data corresponding to the display operation on the second communication module.

[0106] In this embodiment, when there is a display operation on the display module, a communication request is sent to the second communication module, so that the display content corresponding to the display operation can be obtained from the first communication module in the refrigerator body through the second module, thereby ensuring the accuracy of the display content on the display device while achieving the effect of low power consumption of the display device.

[0107] Further, based on the above embodiment, in one of the exemplary embodiments provided in the present application, the above controller is further configured to perform the following steps S410 and S420, which are described in detail as follows:

[0108] Step S410, controlling the display module to enter an on state according to a preset frequency;

[0109] Step S420: When the display module is turned on, a turn-on signal is sent to the second communication module to update the display content on the display module based on the communication data on the second communication module.

[0110] Specifically, in the present embodiment, under normal circumstances, in order to reduce the power consumption of the display device, the display module in the display device is generally in a sleep state, but for the convenience of the user, the display module can be awakened at a preset frequency. When the display module is awakened, a start signal is also sent to the second communication module in the display device, so that the second communication module is in an on state and can normally obtain the communication data sent by the first communication module in the refrigerator body.

[0111] Exemplarily, in order to reduce the power consumption of the display device, the display module and the second communication module of the display device are both in a sleep state. However, in order not to affect the normal use of the user, the display module in the sleep state will be awakened at a preset frequency. After the display module is awakened, a start signal is sent to the second communication module, and the second communication module communicates and interacts with the first communication module in the refrigerator body according to the display requirements of the display module, so as to obtain relevant data from the first communication module in the refrigerator body and display it on the display module. After the display content on the display module is updated and maintained for a period of time, while ensuring that there is no communication task being executed on the second communication module, the display module and the second communication module are controlled to enter a sleep state to reduce the power consumption of the display device.

[0112] In some feasible embodiments, the display module in the display device may be an electronic ink screen or a low-power LCD display. Since the electronic ink screen can maintain normal display without power supply and only consumes power when updating content, the electronic ink screen may be given priority.

[0113] In this embodiment, the display screen is controlled to enter an on state according to a preset frequency. When the display screen is in the on state, an on signal is sent to the second communication module to update the display content on the display module based on the communication data on the second communication module. This ensures that the display module of the display device is in low power consumption while also ensuring the accuracy of the display content on the display module in the on state.

[0114] Further, based on the above embodiment, in one of the exemplary embodiments provided in the present application, the above controller is further configured to perform the following steps, which are described in detail as follows:

[0115] If the on time of the display module reaches longer than the preset on time and no display operation for the display module is received, the display module is controlled to enter a dormant state.

[0116] Specifically, in order to reduce the power consumption of the display device, when it is detected that the activation time of the display module has reached a preset activation time and no display operation triggered by a function button on the display device is received, the display module can be controlled to enter a sleep state.

[0117] Exemplarily, when the display module of the display device is working normally, the user can refresh the display content on the display module through the function button, and exchange data with the first communication module in the refrigerator body through the second communication module according to the needs of the refresh operation, so as to obtain the display content corresponding to the refresh operation. However, when the display module is turned on for a preset time and no display operation triggered by the function button is received, the display module can be controlled to enter a dormant state, and the second communication module can also be controlled to enter a dormant state. Among them, the preset dormant frequency of the display module in the display device can be the same as or different from the preset dormant frequency of the second communication module, and this application does not impose any restrictions on this.

[0118] In addition, in some feasible embodiments, in order to achieve the effect of energy saving and emission reduction and low power consumption of the refrigerator, the first communication module in the refrigerator body can also be controlled to enter a sleep state according to a preset sleep frequency, wherein the preset sleep frequency of the first communication module can be the same as or different from the preset sleep frequency of the second communication module in the display device, and the present application does not impose any restrictions on this.

[0119] In this embodiment, when the display module is turned on for a preset period of time exceeding the preset period of time and no display operation on the display module triggered by a key function is received, the display module and the second communication module are controlled to enter a sleep state, thereby achieving a low power consumption effect of the display module and further achieving a low power consumption effect of the entire display device.

[0120] Further, based on the above embodiment, please refer to Figure 6 In one of the exemplary embodiments provided in the present application, a sensing module is further provided in the refrigerator, wherein the sensing module is configured to perform the following steps, which are described in detail as follows:

[0121] If the target object is sensed, an opening signal is sent to the second communication module, and a communication connection is established between the first communication module and the second communication module;

[0122] If the target object is not sensed, a sleep signal is sent to the second communication module, and the communication connection between the first communication module and the second communication module is disconnected.

[0123] Specifically, when the user enters the working range of the sensing module, the sensing module sends an opening signal to the second communication module of the display device, and establishes a communication connection between the first communication module in the refrigerator box and the second communication module in the display device, so that when the user enters the working range of the sensing module, before the user triggers the display operation, the communication connection between the first communication module in the refrigerator box and the second communication module is established, thereby shortening the user's waiting time for the communication interval between the refrigerator box and the display device. In addition, in some other achievable embodiments, if the user sets the temperature in the refrigerator box or adjusts the operating mode of the refrigerator based on near-field communication through other terminals, the communication connection between the first communication module in the refrigerator box and the second communication module of the display device can be established in advance when the sensing module senses that the user is close to the refrigerator, thereby shortening the time for the user to wait for the first communication module and the second communication module to establish a communication connection. In addition, in order to ensure the low power consumption of the refrigerator display module, when no user is detected to be close to the refrigerator within the working range of the sensing module, a sleep signal is sent to the second communication module in the display module to reduce the consumption of electric energy by the second communication module, thereby achieving low power consumption of the display module.

[0124] Exemplarily, if the sensing module in the refrigerator body senses that a user is approaching the refrigerator, or senses the presence of the user within the working range of the sensing module, or senses that the sensing signal of the user is getting stronger and stronger, it means that the user is gradually approaching the refrigerator, and then a start signal can be sent to the second communication module in the display device that is in a dormant state to establish a communication connection between the first communication module and the second communication module in the refrigerator body, so that when the user approaches the refrigerator, the communication connection between the first communication module and the second communication module in the refrigerator body is established in advance, avoiding the user from triggering the communication connection between the first communication module and the second communication module through the function button on the display device, shortening the time for the user to wait for the first communication module and the second communication module to establish a communication connection, improving the intelligence of the communication between the display device and the refrigerator body, and improving the user's experience. On the other hand, if the presence of the user cannot be sensed within the working range of the sensing module, or the sensed user signal is getting weaker and weaker, it means that the user is gradually moving away from the refrigerator, and then the second communication module in the display device can send a dormant signal, and disconnect the communication connection between the first communication module in the refrigerator body and the second communication module of the display device, thereby ensuring low communication consumption and low power consumption of the display device.

[0125] In addition, in some feasible embodiments, if the second communication module in the display device receives a start signal sent from the refrigerator body side (for example, a sensing module, a first communication module, or a controller inside the refrigerator body, etc.), if the second communication module is awakened in a sleep state, then based on the start-up duration and start-up time point of the second communication module, the preset sleep frequency of the second communication module is adjusted, or the sleep or start-up time point of the second communication module is postponed.

[0126] In this embodiment, on the one hand, when it is sensed that the target object is approaching the refrigerator, the second communication module in the display device is awakened and a communication connection is established between the first communication module and the second communication module, thereby shortening the time it takes for the display device to respond to user operations and improving the user experience. On the other hand, when the target object is not sensed, the second communication module is promptly controlled to enter a sleep state, thereby achieving the effect of low power consumption and communication of the display device.

[0127] Please refer to Figure 7 , Figure 7 FIG. 1 is a schematic diagram of a simplified flow chart of controlling a display device in a refrigerator in an exemplary application scenario. Figure 7 In the application scenario shown, it is determined whether the light intensity in the current environment is greater than the preset light intensity. If the light intensity in the current environment is greater than the preset light intensity, the solar panel in the power supply module of the display device is connected to the power supply circuit. If the light intensity in the current environment is less than the preset light intensity, the energy storage unit in the power supply module of the display device is connected to the power supply circuit. On the other hand, the display module and / or the second communication unit in the display device are controlled to enter a dormant state according to the preset dormancy frequency. If the on-time of the second communication module exceeds the preset on-time, the time difference between the actual on-time of the second communication module and the preset on-time is calculated to adjust the preset dormancy frequency based on the time difference; if a display operation for the display module triggered by a function key is received, a communication request is sent to the second communication module based on the display operation, so as to obtain the display content corresponding to the display operation from the first communication module through the second communication module.
