Description

Technical Field

[0001] This application relates to the field of refrigerators, and in particular to a refrigerator and a method for displaying its interface. Background Technology

[0002] With the continuous development of the trend of integrating smart home appliances with home aesthetics, refrigerator door display technology has gradually evolved from traditional button panels to glass touch display panels. Due to its advantages such as aesthetics, ease of cleaning, and enhanced product quality, glass door display technology has become one of the mainstream features of high-end refrigerators.

[0003] In traditional technologies, the display solutions for white glass doors mainly involve reserving a black display area on the white glass to form a black display panel, achieving a hidden and visible effect through high-transmittance glass, or using electrochromic glass in certain areas to achieve a hidden and visible effect by controlling the color change through voltage.

[0004] However, the black-out display solution presents an abrupt black block when the screen is off, disrupting the overall aesthetics of the white glass door, while the hidden display solution displays blurry images and has low user visibility in strong light. Therefore, it is difficult to simultaneously meet the comprehensive requirements of appearance uniformity, display clarity, and cost control for glass doors of the same color. Summary of the Invention

[0005] This application provides a refrigerator and its interface display method to avoid optical crosstalk between the light-emitting units inside the refrigerator panel, thereby improving the refrigerator display effect.

[0006] In a first aspect, some embodiments provide a refrigerator, including:

[0007] The cabinet door includes a light-transmitting panel and a recess; the recess is formed inside the cabinet door and located on the side of the light-transmitting panel facing the inside of the refrigerator;

[0008] A display device, disposed within a recess, is configured to display the control interface of a refrigerator; the display device includes a side-inlet light guide assembly; the side-inlet light guide assembly includes at least one light-emitting unit.

[0009] A light-shielding isolation dam is set on the side of the light-transmitting panel facing the display device. The light-shielding isolation dam encloses the display area on the inner side of the light-transmitting panel, and the orthographic projection of the display device on the light-transmitting panel is located within the display area. The light-shielding isolation dam includes a light shield corresponding to each light-emitting unit, and each light shield is set on the periphery of the corresponding light-emitting unit. Along the direction perpendicular to the side of the light-transmitting panel facing the inside of the refrigerator, each light shield extends from the inner surface of the light-transmitting panel to the surface of the circuit board that carries the light-emitting unit to prevent light crosstalk between adjacent light-emitting units.

[0010] The outer surface of the cabinet door is a single color with no visual markings corresponding to the display area; when the display device is off, the display area is not visible on the outer surface of the cabinet door, and the light-transmitting panel has a uniform appearance color with other areas of the cabinet door;

[0011] The controller, connected to the display device, is configured to:

[0012] In response to a trigger operation on the display device, control the display device to light up and display the control interface;

[0013] If no trigger operation is detected on the control interface within the preset time period, the control display device will be turned off.

[0014] The refrigerator provided in the above embodiment forms a double-layer three-dimensional light-shielding structure by setting a light-shielding isolation dam around the display area on the inner side of the light-transmitting panel and setting a corresponding light-shielding cover around each light-emitting unit, with the light-shielding cover extending from the inner surface of the light-transmitting panel to the surface of the circuit board supporting the light-emitting unit. The outer light-shielding isolation dam defines an independent optical space for the entire display device in terms of physical structure, effectively blocking the diffusion of side-entered light into the non-display area; the inner light-shielding covers constrain each light-emitting unit in an independent optical cavity, blocking the path of lateral leakage and cross-interference of light between adjacent light-emitting units from the source. The outer and inner layers work together to avoid halo pollution at the edge of the display area and eliminate uneven brightness and color mixing caused by crosstalk of multiple light sources inside the display area, so that the icon boundaries are clear and sharp and the picture is pure when lit, and it still has high recognition in strong light environment. The outer surface of the cabinet door is a single color, without any markings or color markings corresponding to the display area. Combined with the uniform appearance of the translucent panel when the screen is off, the display area is completely invisible on the outer surface of the door when closed, visually blending seamlessly with the rest of the door. This fundamentally eliminates the abrupt dark blocks or color differences found in traditional black-and-white displays when the screen is off, achieving the effect of hiding the control interface when the screen is off and significantly improving the overall aesthetics of the door. Furthermore, the display device illuminates synchronously in response to a triggered operation and automatically turns off after a preset period of inactivity, realizing an intelligent interactive experience with on-demand display and reducing overall power consumption through timely power cut-off.

[0015] Secondly, some embodiments also provide an interface display method, including:

[0016] In response to a trigger operation on the display device, control the display device to light up and display the control interface;

[0017] The control display device turns off after a preset time period has elapsed without any detected triggering operation on the control interface.

[0018] The refrigerator includes a door, a display device, and a light-shielding barrier on the side of the light-transmitting panel facing the display device. The display device includes a side-inlet light guide assembly, which includes at least one light-emitting unit. The light-shielding barrier encloses a display area on the inner side of the light-transmitting panel, and the orthographic projection of the display device on the light-transmitting panel is located within the display area. The light-shielding barrier includes light-shielding covers corresponding to each light-emitting unit, and each light-shielding cover is disposed around the corresponding light-emitting unit. Along a direction perpendicular to the side of the light-transmitting panel facing the interior of the refrigerator, each light-shielding cover extends from the inner surface of the light-transmitting panel to the surface of the circuit board carrying the light-emitting unit to prevent light crosstalk between adjacent light-emitting units. The outer surface of the door is a single color without any visual markings corresponding to the display area. When the display device is closed, the display area is not visible on the outer surface of the door, and the light-transmitting panel and other areas of the door have a uniform appearance color.

[0019] The refrigerator interface display method provided in the above embodiment forms a double-layer three-dimensional light-shielding structure by setting a light-shielding isolation dam around the display area on the inner side of the light-transmitting panel and setting a corresponding light-shielding cover around each light-emitting unit, with the light-shielding cover extending from the inner surface of the light-transmitting panel to the surface of the circuit board supporting the light-emitting unit. The outer light-shielding isolation dam defines an independent optical space for the entire display device in terms of physical structure, effectively blocking the diffusion of side-entered light into the non-display area; the inner light-shielding covers constrain each light-emitting unit in an independent optical cavity, blocking the path of lateral leakage and cross-interference of light between adjacent light-emitting units from the source. The outer and inner layers work together to avoid halo pollution at the edge of the display area and eliminate uneven brightness and color mixing caused by crosstalk of multiple light sources inside the display area, so that the icon boundaries are clear and sharp and the picture is pure when lit, and it still has high recognition in strong light environment. The outer surface of the cabinet door is a single color, without any markings or color markings corresponding to the display area. Combined with the uniform appearance of the translucent panel when the screen is off, the display area is completely invisible on the outer surface of the door when closed, visually blending seamlessly with the rest of the door. This fundamentally eliminates the abrupt dark blocks or color differences found in traditional black-and-white displays when the screen is off, achieving the effect of hiding the control interface when the screen is off and significantly improving the overall aesthetics of the door. Furthermore, the display device illuminates synchronously in response to a triggered operation and automatically turns off after a preset period of inactivity, realizing an intelligent interactive experience with on-demand display and reducing overall power consumption through timely power cut-off.

[0020] Thirdly, some embodiments also provide a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, performs the following steps:

[0021] In response to a trigger operation on the display device, control the display device to light up and display the control interface;

[0022] The control display device turns off after a preset time period has elapsed without any detected triggering operation on the control interface.

[0023] The refrigerator includes a door, a display device, and a light-shielding barrier on the side of the light-transmitting panel facing the display device. The display device includes a side-inlet light guide assembly, which includes at least one light-emitting unit. The light-shielding barrier encloses a display area on the inner side of the light-transmitting panel, and the orthographic projection of the display device on the light-transmitting panel is located within the display area. The light-shielding barrier includes light-shielding covers corresponding to each light-emitting unit, and each light-shielding cover is disposed around the corresponding light-emitting unit. Along a direction perpendicular to the side of the light-transmitting panel facing the interior of the refrigerator, each light-shielding cover extends from the inner surface of the light-transmitting panel to the surface of the circuit board carrying the light-emitting unit to prevent light crosstalk between adjacent light-emitting units. The outer surface of the door is a single color without any visual markings corresponding to the display area. When the display device is closed, the display area is not visible on the outer surface of the door, and the light-transmitting panel and other areas of the door have a uniform appearance color.

[0024] The readable storage medium provided in the above embodiments stores a computer program that, when executed by a processor, forms a double-layer three-dimensional light-shielding structure by setting a light-shielding isolation dam around the display area inside the light-transmitting panel and setting a corresponding light-shielding cover around each light-emitting unit, with the light-shielding cover extending from the inner surface of the light-transmitting panel to the surface of the circuit board supporting the light-emitting unit. The outer light-shielding isolation dam physically defines an independent optical space for the entire display device, effectively blocking side-entered light from diffusing into non-display areas; the inner light-shielding covers confine each light-emitting unit to an independent optical cavity, blocking the path of lateral light leakage and cross-interference between adjacent light-emitting units from the source. The outer and inner layers work together to avoid halo pollution at the edge of the display area and eliminate uneven brightness and color mixing caused by crosstalk from multiple light sources within the display area, resulting in clear and sharp icon boundaries, a pure image, and high recognizability even in strong light environments. The outer surface of the cabinet door is a single color, without any markings or color markings corresponding to the display area. Combined with the uniform appearance of the translucent panel when the screen is off, the display area is completely invisible on the outer surface of the door when closed, visually blending seamlessly with the rest of the door. This fundamentally eliminates the abrupt dark blocks or color differences found in traditional black-and-white displays when the screen is off, achieving the effect of hiding the control interface when the screen is off and significantly improving the overall aesthetics of the door. Furthermore, the display device illuminates synchronously in response to a triggered operation and automatically turns off after a preset period of inactivity, realizing an intelligent interactive experience with on-demand display and reducing overall power consumption through timely power cut-off.

[0025] Fourthly, some embodiments also provide a computer program product, including a computer program that, when executed by a processor, performs the following steps:

[0026] In response to a trigger operation on the display device, control the display device to light up and display the control interface;

[0027] The control display device turns off after a preset time period has elapsed without any detected triggering operation on the control interface.

[0028] The refrigerator includes a door, a display device, and a light-shielding barrier on the side of the light-transmitting panel facing the display device. The display device includes a side-inlet light guide assembly, which includes at least one light-emitting unit. The light-shielding barrier encloses a display area on the inner side of the light-transmitting panel, and the orthographic projection of the display device on the light-transmitting panel is located within the display area. The light-shielding barrier includes light-shielding covers corresponding to each light-emitting unit, and each light-shielding cover is disposed around the corresponding light-emitting unit. Along a direction perpendicular to the side of the light-transmitting panel facing the interior of the refrigerator, each light-shielding cover extends from the inner surface of the light-transmitting panel to the surface of the circuit board carrying the light-emitting unit to prevent light crosstalk between adjacent light-emitting units. The outer surface of the door is a single color without any visual markings corresponding to the display area. When the display device is closed, the display area is not visible on the outer surface of the door, and the light-transmitting panel and other areas of the door have a uniform appearance color.

[0029] The computer program provided in the above embodiments, when executed by the processor, forms a double-layer three-dimensional light-shielding structure by setting a light-shielding isolation dam around the display area inside the light-transmitting panel and setting a corresponding light-shielding cover around each light-emitting unit, with the light-shielding cover extending from the inner surface of the light-transmitting panel to the surface of the circuit board supporting the light-emitting unit.

[0045] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with this application. They are merely examples of systems and methods consistent with some aspects of this application as detailed in the claims.

[0046] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0047] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0048] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0049] The term "module" refers to any known or subsequently developed hardware, software, firmware, artificial intelligence, fuzzy logic, or combination of hardware and / or software code that is capable of performing the functions associated with that element.

[0050] The refrigerator 1 provided in this application will now be described with reference to the accompanying drawings. The overall structure of the refrigerator 1 is as follows: Figure 1 As shown. Refrigerator 1 includes a cabinet 10 and a processing device 20.

[0051] like Figure 2 As shown, the housing 10 has at least one storage compartment.

[0052] Storage rooms are typically divided into freezer rooms and refrigerator rooms (referred to as refrigerator rooms). They can also be further divided into chambers with special functions, such as chambers for storing fruits and vegetables. Refrigerator rooms can maintain a temperature range of approximately 4°C to store food, medicine, or biological agents in a refrigerated state. Freezer rooms can maintain a temperature range of approximately -18°C to store food, medicine, or biological agents in a frozen state.

[0053] The storage compartment has an opening that can be opened and closed via a door 11 hinged to the outer casing, or via a drawer 12. When a refrigerator compartment and a freezer compartment are provided, one opening can be opened and closed via a door (e.g., the refrigerator compartment), and the other opening can be opened and closed via a drawer 12 (e.g., the freezer compartment).

[0054] The housing 10 employs a vapor compression refrigeration cycle to generate energy for maintaining the target temperature. The refrigeration cycle consists of a compressor 161, a condenser, a throttling device, and an evaporator. The refrigeration cycle involves a series of processes, including compression, condensation, expansion, and evaporation, to cool the storage compartment and maintain an ideal low-temperature storage environment inside.

[0055] In a vapor compression refrigeration cycle, a low-temperature, low-pressure refrigerant enters the compressor 161, which compresses it into a high-temperature, high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser, where the condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0056] The throttling device causes the high-temperature, high-pressure liquid refrigerant formed in the condenser to expand into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant that has expanded in the throttling device and returns the low-temperature, low-pressure refrigerant gas to the compressor 161. The evaporator can achieve a cooling effect by exchanging heat with the material to be cooled through the latent heat of refrigerant evaporation. In this application, the evaporator exchanges heat with air to form air for cooling the storage compartment, thereby cooling the storage compartment. The throttling device can be a capillary tube.

[0057] A filter is also installed downstream of the condenser. The filter is used to filter impurities in the refrigerant, improve the heat exchange efficiency of the refrigeration unit, and reduce the risk of pipe blockage.

[0058] A liquid receiver can also be installed on the suction side of the compressor 161. The liquid receiver is used to separate the refrigerant into gas and liquid phases. The liquid receiver is a shell-shaped component. The gas-liquid mixed refrigerant fluid enters the liquid receiver for basic phase separation. The gas enters the gas passage and undergoes gravity settling to separate droplets, while the liquid enters the liquid space and separates into bubbles. The gas flows out from the gas outlet and is then drawn into the compressor 161, preventing the compressor 161 from carrying liquid in the suction and reducing the service life of the compressor 161.

[0059] The compressor 161 and condenser can be located at the lower rear of the housing, while the evaporator can be located at the rear of the housing corresponding to the storage compartment. The evaporator and condenser can also be arranged in other locations according to the industrial design of the housing 10, which will not be listed here. The location where the evaporator is located has sufficient space to allow air to flow. The air is driven by the fan 162 to deliver the air generated by the evaporator for cooling the storage compartment to the target location and to draw in air from the storage compartment, forming an air circulation. In one or more embodiments of this application, the fan 162 includes a refrigeration fan and a freezing fan. In one or more embodiments of this application, the fan 162 can also be configured in conjunction with the condenser.

[0060] In one or more embodiments of this application, the evaporator may also be divided into two parts for the refrigerator compartment and the freezer compartment, referred to as the refrigerator compartment cooler and the freezer compartment cooler.

[0061] A defrosting element is provided in the housing 10. The defrosting element is configured to generate heat for defrosting the evaporator, thereby putting the evaporator in a defrosting state. In one or more embodiments of this application, the defrosting element includes a defrosting heater 163, which may be an electric heating tape or an electric heater. In one or more embodiments of this application, the defrosting element may also be a combination of an electric heating tape or an electric heater, and a heat exchanger or heat exchange piping. When defrosting conditions are met, the heat exchange piping is opened, and the high-temperature, high-pressure refrigerant discharged from the compressor 161 enters the heat exchange piping, exchanges heat with the surrounding air, raises the air temperature, and further provides heat to melt the frost layer on the evaporator surface, thereby putting the evaporator in a defrosting state. The heat exchange piping may be located below the evaporator, utilizing the principle that hot air has a lower density and rises to guide the air to remove the ice or frost layer on the evaporator. The defrosting element composed of an electric heating tape or an electric heater may also be located around the evaporator in other positions, such as above or to one side of the evaporator.

[0062] A display 164 is installed on the cabinet 10.

[0063] The cabinet 10 is equipped with a refrigeration system, which is configured to transfer heat from the inside of the refrigerator to the outside through the circulation of refrigerant.

[0064] like Figure 3As shown in the figure, the hardware configuration of the processing device 20 is as follows.

The processor 201 may be a dedicated processor 201, a central processing unit, etc. The processor 201 can access the storage unit to execute instructions or application programs stored in the storage unit to achieve related functions. The display device 204 is a display device 204 for displaying various information, the operation device 205 is an operation device for receiving various operations, and the drive device 207 is a hardware terminal that interacts with the storage medium. In one or more embodiments of this application, the storage medium includes media such as CD-ROM, floppy disk, and optical-magnetic-optical disk that record information in an optical, electrical, or magnetic manner. The storage medium may also be a semiconductor memory such as ROM or flash memory that records information in an electrical manner.

[0065] In one or more embodiments of this application, the processing device 20 may be a controller 13. The controller 13 is disposed in the housing 10.

[0066] In one or more embodiments of this application, the processing device 20 may be communicatively connected to the controller 13, for example, by a terminal device 15 and / or a cloud server 14.

[0067] In one or more embodiments of this application, some functions of the processing device 20 may be implemented by the controller 13, and some functions may be implemented by the terminal device 15 and / or the cloud server 14.

[0068] Controller 13 can communicate with terminal device 15 and / or server 14. The network between controller 13 and terminal device 15, or between controller 13 and server 14, can be the Internet, cellular network, Wi-Fi network, low power wide area network (LPWAN), WAN, LAN, etc., based on standards and protocols such as LoRa, Sigfox, and NB-IoT.

[0069] The cabinet 10 can be used in home environments to store daily necessities such as food and cold drinks; it can also be used in commercial places such as restaurants, hotels, supermarkets, and convenience stores to store ingredients, food and beverages to meet customer needs; and it can also be used in places such as hospitals and laboratories to store medicines and biological samples to meet medical and scientific research needs.

[0070] Server 14 can provide various network services, such as resource and data access for refrigerator 1 controller 13 and terminal device 15. Server 14 has higher performance and reliability. Server 14 can connect to multiple refrigerator 1 controllers 13, multiple terminal devices 15, and other smart home appliance terminals.

[0071] Terminal device 15 is an electronic device with intelligent functions. It can connect to the aforementioned networks to achieve functions such as remote control, data exchange, and human-computer interaction. Terminal device 15 includes smartphones, tablets, smart speakers, wearable devices, smart home appliances (such as smart TVs), and smart in-vehicle devices, etc. The interaction methods between terminal device 15 and users include, but are not limited to: operating on the screen with a finger or stylus, performing various operations through buttons, voice control, gesture control, iris recognition, and facial recognition, etc.

[0072] In one or more embodiments of this application, the housing 10 is communicatively connected to the sensor assembly 30. At least a portion of the sensors in the sensor assembly 30 are disposed within the housing 10.

[0073] like Figure 4 and Figure 5 As shown, in one or more embodiments of this application, the sensor assembly 30 includes at least one temperature sensor; the temperature sensor may include at least one of a compartment temperature sensor 31, an evaporator temperature sensor 32, and an ambient temperature sensor 33.

[0074] In one or more embodiments of this application, at least one controller is connected to a temperature sensor. The controller is configured to: determine initial control parameters corresponding to the current ambient temperature based on a parameter initialization model; wherein the parameter initialization model is obtained through reinforcement learning based on refrigerator operating data under a preset sample ambient temperature; for each iteration, control the refrigerator to operate in a single cycle according to the refrigerator control parameters corresponding to the current iteration, and obtain the performance evaluation data corresponding to the refrigerator's operation in this single cycle; wherein the refrigerator control parameters in the first iteration are the initial control parameters; if the performance evaluation data corresponding to the current single cycle meets a preset update condition, update the refrigerator control parameters corresponding to the current iteration based on the performance evaluation data corresponding to the current single cycle to obtain the refrigerator control parameters corresponding to the next iteration; continue executing the next iteration until the performance evaluation data in the latest iteration no longer meets the preset update condition.

[0075] For example, the compartment temperature sensor 31 includes a refrigerator compartment temperature sensor 311 and a freezer compartment temperature sensor 312. The refrigerator compartment temperature sensor 311 is installed in the refrigerator compartment of the cabinet 10 to detect the temperature of the refrigerator compartment; the freezer compartment temperature sensor 312 is installed in the freezer compartment of the cabinet 10 to detect the temperature of the freezer compartment.

[0088] Currently, in order to achieve display functions on white glass doors, the industry often adopts methods such as... Figure 6 The display panel shown, namely (A) in the figure, has a black display area reserved on the glass to form a black display panel, using the black background to highlight the displayed icons; (B) in the figure uses high-transmittance glass to achieve the hidden effect, so that the display area can be integrated with the door as much as possible when the screen is off; in addition, there is another type that uses electrochromic glass in certain areas, which uses voltage to control the glass to change color to achieve the display content to be displayed and hidden. However, while the black-and-white display solution offers good clarity, the abrupt black block in the off-screen state creates a stark visual contrast with the glass panel (especially the white panel), completely ruining the overall display effect of the door and failing to meet the pursuit of a seamless integration with home décor in high-end appliances. The high-transmittance concealed display solution, while offering better hiding when the screen is off than the black-and-white solution, suffers from extremely poor visibility and low user recognition in bright light due to the lack of a background color. Furthermore, backlighting is prone to crosstalk within the glass, causing halos and blurring around icons, severely impacting the user experience. While the electrochromic solution can balance screen hiding and display on / off, its material costs are extremely high, and the response speed and reliability of the electrochromic material significantly degrade under the long-term low-temperature, high-humidity operating environment of the refrigerator door. Therefore, existing technologies cannot simultaneously meet the comprehensive requirements of white glass doors in terms of aesthetic integration, display clarity, and cost control, and urgently need improvement.

[0089] To overcome the above problems, in some alternative embodiments, see Figure 7 A refrigerator is provided, which includes: a door 11, a display device 204, and a light-shielding dam 40.

[0090] The door 11 refers to a rotatable component connected to the refrigerator body via hinges or similar means, used to open or close the storage compartment opening. The door 11 includes a light-transmitting panel 110 and a recess 111. The light-transmitting panel 110 is a plate-like component constituting the exterior surface of the door, typically made of transparent materials such as glass. It serves both as a decorative layer for the door's appearance and as a means for light to pass through for display or transparency. The recess 111 is located inside the door and on the side of the light-transmitting panel facing the interior of the refrigerator. It refers to a structural recessed space inside the door, such as a recessed area formed on the inner liner of the door, which can be used to accommodate functional components such as the display system and sealing gaskets.

[0091] The display device 204 refers to a functional component disposed within the recess, configured to display the refrigerator's control interface and enable user interaction. The control interface is a visual operation panel displayed on the touch display component when the display device is illuminated, used by the user to view the refrigerator's operating status and perform functional controls. The control interface may include interactive elements such as a temperature setting entry, an operating mode selection entry, a fault indication area, and a time display area.

[0092] The light-shielding isolation dam 40 is disposed on the side of the light-transmitting panel facing the display device. The light-shielding isolation dam encloses the display area within the light-transmitting panel to block light. The light-shielding isolation dam 40 is arranged around the display area, and the orthographic projection of the display device onto the light-transmitting panel is located within the display area. The light-shielding isolation dam 40 is configured to extend continuously or intermittently along the outer periphery of the display area, forming a closed or substantially closed enclosure structure, thereby defining an independent optical space within the light-transmitting panel. The light-shielding isolation dam 40 has a certain height in a direction perpendicular to the light-transmitting panel to block light emitted from the side-entry light guide assembly from diffusing outwards from the display area, preventing light crosstalk between adjacent light-emitting units and halo phenomena at the edges of the display area.

[0093] In some embodiments, a diffuse scattering layer is provided on the side surface of the light-transmitting panel facing the display device and at the position corresponding to the display area. The diffuse scattering layer is configured to diffuse the light emitted by the display device evenly.

[0094] For example, a diffuse scattering layer refers to an optical processing structure layer disposed on the side surface of the light-transmitting panel facing the display device and corresponding to the display area, configured to uniformly diffuse the light emitted by the display device. The diffuse scattering layer can be formed on the inner surface of the light-transmitting panel by physical or chemical means, such as sandblasting, etching, frosting, or coating with a scattering coating, to form a rough surface layer with a microscopic uneven structure or a uniformly distributed scattering particle layer in the corresponding display area of ​​the glass panel. The extent of the diffuse scattering layer on the light-transmitting panel corresponds to the display area enclosed by the light-shielding isolation dam, so that when the light emitted by the display device passes through the light-transmitting panel, it is first scattered by the diffuse scattering layer before being emitted outwards.

[0095] It should be noted that the light-blocking barrier is responsible for constraining the horizontal boundaries of light propagation, preventing light from overflowing the display area; the diffuse scattering layer is responsible for adjusting the spatial distribution of light as it passes through the light-transmitting panel, eliminating bright and dark areas. Working together, when the display is on, the display area exhibits a uniform brightness and clear boundaries; when the display is off, the microstructure of the diffuse scattering layer weakens the interface between the display area and the surrounding glass surface, making the display area visually more integrated with the rest of the door, enhancing the overall unity of the door's appearance when the screen is off.

[0096] In one alternative embodiment, when light emitted from the display device (especially the side-inlet light guide component or touch display component) passes through the light-transmitting panel, the diffuse scattering layer, through its surface microstructure or internal scattering particles, generates optical effects such as transmission, refraction, and reflection of the incident light. This redistributes the originally directional and unevenly distributed light in space, resulting in a more uniform brightness distribution on the emitting surface of the light-transmitting panel. For example, without the diffuse scattering layer, the display area observed by the user exhibits a noticeable grainy texture with alternating bright and dark areas; with the diffuse scattering layer, the display area observed by the user appears as a uniform and soft luminous surface, with clear icons and text boundaries and no obvious backlighting.

[0097] In the above embodiment, a double-layer three-dimensional light-shielding structure is formed by setting a light-shielding isolation dam around the display area on the inner side of the light-transmitting panel and setting a corresponding light-shielding cover around each light-emitting unit, with the light-shielding cover extending from the inner surface of the light-transmitting panel to the surface of the circuit board supporting the light-emitting unit. The outer light-shielding isolation dam defines an independent optical space for the entire display device in terms of physical structure, effectively blocking the diffusion of side-entered light into the non-display area; the inner light-shielding covers constrain each light-emitting unit in an independent optical cavity, blocking the path of lateral leakage and cross-interference of light between adjacent light-emitting units from the source. The outer and inner layers work together to avoid halo pollution at the edge of the display area and eliminate the uneven brightness and color mixing caused by crosstalk of multiple light sources inside the display area, so that the icon boundaries are clear and sharp and the picture is pure when lit, and it still has high recognition in strong light environment. The outer surface of the cabinet door is a single color, without any markings or color markings corresponding to the display area. Combined with the uniform appearance of the translucent panel when the screen is off, the display area is completely invisible on the outer surface of the door when closed, visually blending seamlessly with the rest of the door. This fundamentally eliminates the abrupt dark blocks or color differences found in traditional black-and-white displays when the screen is off, achieving the effect of hiding the control interface when the screen is off and significantly improving the overall aesthetics of the door. Furthermore, the display device illuminates synchronously in response to a triggered operation and automatically turns off after a preset period of inactivity, realizing an intelligent interactive experience with on-demand display and reducing overall power consumption through timely power cut-off.

[0098] In some embodiments, the outer surface of the cabinet door is a single color without any visual markings corresponding to the display area. When the display device is off, the display area is not visible on the outer surface of the cabinet door, and the light-transmitting panel and other areas of the cabinet door have a uniform appearance color. For example, taking a white cabinet door as an example, when the display device is off, the light-transmitting panel and other areas of the cabinet door can both be white, or there can be a slight color difference between the light-transmitting panel and other areas of the cabinet door, so that the user can accurately identify the position of the light-transmitting panel and observe that the light-transmitting panel and the cabinet door are the same or similar in color at a distance. In the above embodiments, by making the display device present a uniform and consistent appearance color with other areas of the refrigerator door when the display device is off, the problem of abrupt black blocks or color differences in the display area when the screen is off, as seen in traditional black display solutions, is completely eliminated. This makes the entire door visually a complete panel, significantly improving the overall appearance of the refrigerator. This screen-off hiding effect can be achieved without relying on controllable color-changing materials such as electrochromic materials, avoiding high material costs and low-temperature reliability risks. In addition, the uniform and consistent appearance color also enhances the user's intuitive perception of the no-display state, making the door present a pure decorative panel effect when there is no interaction, and then clearly lighting up when the user approaches or touches it. This visual contrast from hidden to revealed further enhances the sense of technology and the ritual of interaction. This effect works in conjunction with the light-shielding isolation dam and diffuse scattering treatment layer to create a pure and integrated appearance when the screen is off, and to ensure clear display when lit up, providing users with a high-end user experience that is both beautiful and practical.

[0099] Based on the technical solutions of the above embodiments, some optional embodiments are also provided, see below. Figure 8 The display device shown includes a side-inlet light guide assembly 2041 and a touch display assembly 2042.

[0100] The side-inlet light guide assembly 2041 is a light-emitting component disposed in the outer area of ​​the light-shielding isolation dam and used to provide lateral backlight illumination to the display area. The side-inlet light guide assembly 2041 is configured to guide light into the display area from the lateral edge of the display area to provide uniform backlight illumination for the touch display assembly.

[0101] The touch display component 2042 refers to an interactive component disposed within the display area enclosed by the light-shielding isolation dam, used to display the control interface and receive user touch operations. The touch display component 2042 is configured to present a visual control interface when the display device is lit, allowing the user to view the refrigerator's operating status and perform function control. The touch display component 2042 includes a display module and a touch module. The display module is configured to display the control interface under the drive of the controller. This control interface may include interactive elements such as a temperature setting entry, an operating mode selection entry, a fault prompt area, and a time display area. The touch module is configured to sense the user's touch operation on the control interface and transmit the touch signal to the controller. The display module and the touch module can adopt an integrated structure, i.e., the touch function and the display function are implemented in the same panel, or they can adopt a stacked structure, i.e., the touch module is disposed on the light-emitting side of the display module.

[0102] In some embodiments, the light-emitting units in the side-lit light guide assembly are typically distributed in a dotted or linear pattern. If light passes directly through a smooth, translucent panel, the user will observe bright spots (i.e., the area directly in front of the light-emitting units is significantly brighter) and dark areas (i.e., the area far from the light-emitting units is significantly darker) in the display area. The introduction of the diffuse scattering layer causes each beam of light to be split into multiple transmitted rays in different directions when passing through a rough surface or scattering particle layer, and the energy of a single light source is dispersed over a wider angular range. After the light emitted by multiple light-emitting units is scattered, their respective light spots overlap and diffuse, ultimately forming a uniformly bright luminous surface in a macroscopic vision, making the displayed content clear and soft to the user, with no brightness differences perceptible to the naked eye.

[0103] In some embodiments, this embodiment can also independently spray a light-shielding ink coating layer at its corresponding display position for each side-entry light guide component and touch display component, instead of having to continuously spray along the outer perimeter of the entire display area. Specifically, a local light-shielding coating can be formed around the light emission path of each light-emitting unit or around the marking area of ​​each touch button to independently define the boundary and constrain the light of each display unit. Compared to overall enclosed spraying, this partitioned independent spraying method can further reduce the coverage area of ​​the light-shielding ink, reduce the process difficulty and material cost, and avoid reliability risks such as film cracking and peeling caused by thermal expansion or uneven adhesion of large-area ink layers. In addition, the independent spraying method also makes it easier to optimize the width and thickness of the light-shielding layer for the brightness, color and shape of different display areas, improve the light-shielding accuracy, and retain more original color areas of the light-transmitting panel between each display area when the screen is off, which helps to maintain the transparent texture of the door surface and the consistency of the overall appearance.

[0104] In the above embodiments, by dividing the display device into a side-inlet light guide component and a touch display component, and respectively setting them in the outer area of ​​the light-shielding isolation dam and the enclosed display area, the separation and coordination of light guiding and display functions in physical space are achieved. The side-inlet light guide component provides uniform side backlight illumination from the edge to the display area, avoiding hot spots or shadows that may be generated on the white panel by traditional direct backlight. The touch display component is precisely positioned in the area enclosed by the isolation dam, ensuring the sensitivity of touch operation and the accurate correspondence of the displayed content. The light-shielding isolation dam, as an optical barrier between the two, effectively prevents the side-inlet light from entering the touch display area and causing halo or crosstalk, ensuring the clarity and contrast of the icons when the display interface is lit. The side-inlet design itself also allows the light guide component to be installed concealed at the edge of the panel without adding extra door thickness, which is conducive to the thinning and lightweight design of the refrigerator door.

[0105] Based on the technical solutions of the above embodiments, some optional embodiments are also provided, see below. Figure 9 The light-shielding isolation dam shown is a light-shielding ink coating layer, which is printed on the inner surface of the light-transmitting panel and arranged around the display area.

[0106] In this type of ink coating, the light-blocking ink is often used as a base color layer. A layer of opaque ink is screen-printed around the display area to ensure that no light passes through the non-display areas after illumination, resulting in clear display boundaries. These inks typically use high-opacity pigments such as carbon black and titanium black as their main components. For glass substrates, there are specialized high-opacity inks, characterized by extremely high light-blocking properties, opacity, no pinholes, and good leveling properties. These inks are usually a two-component system (requiring an external curing agent). After baking, they form a strong light-blocking film layer on the glass surface, exhibiting strong adhesion, scratch resistance, and chemical resistance. They are suitable for various glass substrates, including tempered glass and ordinary glass. Printing methods can include at least one of screen printing, pad printing, spraying, inkjet printing, and roller printing.

[0107] In some embodiments, the light-shielding ink coating layer is composed of a light-shielding ink material and is directly adhered to the surface of the light-transmitting panel facing the display device by printing processes such as screen printing, pad printing, or spraying. It extends continuously or intermittently along the outer periphery of the display area, forming a closed or substantially closed enclosing pattern on the inner side of the light-transmitting panel. The light-shielding ink coating layer has a certain thickness in a direction perpendicular to the light-transmitting panel to absorb or reflect light emitted from the side-entry light guide assembly, preventing light leakage outwards from the display area, thereby avoiding halo phenomena at the edges of the display area and light crosstalk between adjacent light-emitting units.

[0108] In some embodiments, the color of the light-shielding ink coating layer can be adjusted according to the hue of the light-transmitting panel to coordinate with the background color of the light-transmitting panel. When the display device is off, the color of the light-shielding ink coating layer blends with the colors of the light-transmitting panel and other areas of the cabinet door, so that the light-transmitting panel and other areas of the cabinet door present a uniform appearance color, avoiding the formation of abrupt color blocks in the display area when the screen is off.

[0109] In some embodiments, the printing position of the light-shielding ink coating layer corresponds to the outer peripheral edge of the display area, its inner boundary defines the boundary of the display area, and its outer boundary extends toward the peripheral area of ​​the light-shielding isolation dam. The width and thickness of the light-shielding ink coating layer can be adapted to the size of the display device, the power of the light-emitting unit, and the optical characteristics of the light-transmitting panel to ensure effective light shielding without occupying additional internal door space, which helps to maintain the thin design of the refrigerator door and the overall structural compactness.

[0110] It should be noted that, as Figure 9 As shown in (A), the light-shielding dam of the light-shielding ink coating layer in this embodiment can be completely adhered to the inner surface of the light-transmitting panel, forming a closed or substantially closed enclosure pattern, thereby optically defining the display boundary. Alternatively, as shown in... Figure 9 As shown in (B), a light-shielding ink coating layer is printed on the inner surface of the light-transmitting panel, and its printing position corresponds to each display area enclosed by the light-shielding cover. In other words, the inner surface of the light-transmitting panel is divided into several local printing areas corresponding to the light-emitting units. The printing process precisely arranges the light-shielding ink coating layer in these local areas, with the outer edge of the ink coating in each area closely matching the shape of the inner wall of the light-shielding cover and completely filling the independent space formed by the light-shielding cover. In this way, each printing area is independent of each other, and its distribution completely corresponds to the array arrangement of the light-emitting units.

[0111] In the above embodiments, by setting the light-shielding isolation dam as a light-shielding ink coating layer printed on the inner surface of the light-transmitting panel, a light-shielding pattern surrounding the display area can be precisely formed on the glass panel using mature processes such as screen printing. The process is simple, mature, and has high processing precision. It does not require the introduction of additional injection molded parts or metal structural parts, which reduces material costs and simplifies the assembly process, making it suitable for mass production at high efficiency. The ink layer is directly attached to the inner surface of the glass, forming an integrated structure with the panel. It does not increase the door thickness or change the original layered spatial layout of the door, which helps to maintain the thin design of the refrigerator door and the overall compact structure. The light-shielding ink coating layer has good light-shielding performance. With its strong adhesion, it can stably and effectively block the light emitted by the side-entry light guide component from overflowing out of the display area, avoiding optical crosstalk between adjacent light-emitting units, and ensuring clear boundaries of the displayed content without halo pollution; the color of the ink layer can be flexibly adjusted according to the hue of the light-transmitting panel, and can naturally blend with the background color of the glass panel when the display device is off, further enhancing the consistency of the appearance color of the display area with other areas of the door when the screen is off, and enhancing the overall pure visual effect of the door; the solution of achieving light-blocking isolation with printed ink has significant advantages in terms of production cost, process reliability, appearance adaptability and mass production feasibility compared to electrochromic or complex optical structures.

[0112] Based on the technical solutions of the above embodiments, some optional embodiments are also provided, see below. Figure 10 The schematic diagram of the light-shielding isolation dam shown indicates that the light-shielding isolation dam 40 is a light-shielding isolation plate that surrounds the display area. In the above embodiment, by setting the light-shielding isolation dam as a light-shielding isolation plate surrounding the display area, a physical barrier is constructed in the form of a plate with a certain structural strength and thickness. This can more reliably block the diffusion of light from the side-entering light guide component to the periphery of the display area. Especially under the requirements of large-size or high-brightness displays, the light-shielding effect of the isolation plate is more stable and durable than that of an ink coating. It is not prone to light-shielding performance degradation due to temperature difference deformation of the glass panel or long-term light aging, significantly improving the long-term reliability of the product in the wide temperature range operating environment of the refrigerator. As an independent prefabricated component, the light-shielding isolation plate can be independently processed and quality controlled before the door assembly. During inspection and assembly, the isolation plate is directly positioned and installed inside the light-transmitting panel, reducing the precision requirements and yield loss risks of direct printing on the glass panel. It also facilitates flexible replacement of the isolation plate's specifications or materials according to different display sizes or appearance requirements, improving the flexibility of product line expansion and design iteration efficiency. The isolation plate itself has a certain supporting thickness, and after installation, it can form a barrier structure around the display area, not only playing a role in light shielding, but also providing limiting and positioning assistance for the touch display components during assembly, indirectly improving the installation position accuracy and consistency of the display module, and reducing display or touch offset problems caused by assembly deviations.

[0113] Based on the technical solutions of the above embodiments, some optional embodiments are also provided, see below. Figure 11 The schematic diagram of the display device shown shows that the side-entry light guide assembly includes multiple light-emitting units, and the light-shielding isolation dam includes light shields corresponding to each light-emitting unit. Each light shield is disposed around the corresponding light-emitting unit. Along the direction perpendicular to the light-transmitting panel towards the inside of the refrigerator, each light shield extends from the inner surface of the light-transmitting panel to the surface of the circuit board carrying the light-emitting unit to prevent light crosstalk between adjacent light-emitting units.

[0114] The light-emitting unit refers to a light-emitting element disposed in the side-inlet light guide assembly, used to emit light to provide side backlight illumination. The light-emitting unit is configured to be turned on or off under the control of the controller; when turned on, it provides illumination to the display area, and when turned off, it stops emitting light.

[0115] In some embodiments, the light-emitting unit may use a light-emitting diode (LED) as the light source, including but not limited to monochrome LEDs, multicolor LEDs, or white LEDs. The specific selection of the light-emitting unit can be adapted according to the size of the display area, target brightness, color temperature requirements, and power consumption limitations. Multiple light-emitting units may be arranged along one side of the edge of the display area, on opposite sides, or circumferentially to provide a suitable lighting scheme according to the size and brightness requirements of the display area.

[0116] In some embodiments, a light shield is provided around each light-emitting unit. The light shield is part of a light-shielding isolation dam, and along the direction perpendicular to the light-transmitting panel, the height of each light shield is not less than the height of the corresponding light-emitting unit to prevent light crosstalk between adjacent light-emitting units. The light shield confines the light emitted by each corresponding light-emitting unit within its own independent optical channel, cutting off the path of lateral leakage and cross-interference of light between adjacent light-emitting units from the source.

[0117] In the above embodiments, by setting independent light shields for each of the multiple light-emitting units of the side-entry light guide assembly, and limiting each light shield to extend from the inner surface of the light-transmitting panel to the surface of the circuit board carrying the light-emitting unit in a direction perpendicular to the light-transmitting panel towards the inside of the refrigerator, light crosstalk between adjacent light-emitting units is prevented. Precise optical isolation is achieved at the level of a single light-emitting unit. Each light shield strictly confines the light emitted by its internal light-emitting unit within its own independent optical channel, cutting off the path of lateral light leakage and crosstalk between adjacent light-emitting units from the source. This completely eliminates undesirable phenomena such as uneven brightness, spot shift, or color mixing in the display area caused by light crosstalk, thereby significantly improving the image purity and detail clarity of the display interface. Compared to an integrated baffle, the one-to-one isolation method is more targeted. The height and shape of each light shield can be independently optimized according to the emission angle, power and position of the corresponding light-emitting unit. It can fully cover the side light-emitting surface of the light-emitting unit without excessively blocking its effective light emission direction toward the light guide plate. It maximizes light energy utilization while ensuring crosstalk prevention and avoids reducing the overall display brightness or increasing energy consumption due to excessive light blocking. The structural design of the independent light shield allows the spacing between adjacent light-emitting units to be further compressed, which is conducive to arranging more light-emitting units or achieving a more compact layout in the limited space of the door edge. This provides higher brightness and more uniform backlighting for the display area without worrying about exacerbating crosstalk problems due to dense unit arrangement, thereby expanding the design freedom.

[0118] Based on the technical solutions of the above embodiments, some optional embodiments are also provided, see below. Figure 12 The refrigerator diagram shown includes:

[0119] The refrigerator door 11 includes a light-transmitting panel 110 and a recess 111. The recess 111 is located inside the door and on the side of the light-transmitting panel 110 facing the interior of the refrigerator. A diffuse scattering layer is provided on the surface of the light-transmitting panel 110 facing the display device 204, corresponding to the display area. The diffuse scattering layer is configured to uniformly diffuse the light emitted by the display device 204. When the display device 204 is closed, the light-transmitting panel 110 and other areas of the refrigerator door 11 have a uniform appearance color.

[0120] Display device 204, disposed within recess 111, is configured to display the control interface of the refrigerator; display device 204 includes a side-inlet light guide component 2041 and a touch display component 2042; the side-inlet light guide component 2041 is disposed in the outer area of ​​the light-shielding isolation dam and is configured to provide side backlight illumination to the display area; the touch display component 2042 is disposed within the display area enclosed by the light-shielding isolation dam and is configured to display the control interface and receive touch operations from the user.

[0121] A light-shielding isolation dam 40 is disposed on the side of the light-transmitting panel facing the display device 204. The light-shielding isolation dam 40 encloses a display area on the inner side of the light-transmitting panel 110, and the orthographic projection of the display device 204 on the light-transmitting panel 110 is located within the display area. The light-shielding isolation dam 40 is a light-shielding ink coating layer, which is printed on the inner surface of the light-transmitting panel 110 and arranged around the display area. The light-shielding isolation dam 40 is also a light-shielding isolation plate, which is arranged around the display area. The side-entry light guide assembly 2041 includes multiple light-emitting units, and the light-shielding isolation dam includes multiple light-shielding covers corresponding to the multiple light-emitting units. Each light-shielding cover is disposed around the corresponding light-emitting unit. Along the direction perpendicular to the light-transmitting panel, the height of each light-shielding cover is not less than the height of the corresponding light-emitting unit to prevent light crosstalk between adjacent light-emitting units.

[0122] It should be noted that the above Figure 9 This is a schematic diagram of a refrigerator where the light-shielding barrier is merely a layer of light-shielding ink coating. It also includes schematic diagrams showing the overall printing of the light-transmitting surface of the display area corresponding to the display device, and the separate printing of the light-transmitting surfaces of the display areas corresponding to each side's light guide assembly 2041 and touch display assembly 2042. The above... Figure 10 This is a schematic diagram of a refrigerator where the shading barrier is simply a single, integral shading panel. Figure 11 This is a schematic diagram of a refrigerator where the light-shielding barrier is merely a light-shielding panel, and each side of the light guide assembly 2041 and touch display assembly 2042 is provided with a separate light-shielding cover. Figure 12 A schematic diagram of a refrigerator with two types of light-shielding barriers: one with a light-shielding ink coating layer and the other with a light-shielding barrier plate.

[0123] Based on the technical solutions of the above embodiments, some optional embodiments are also provided, see below. Figure 13 The interface display method shown is applied to the controller in a refrigerator, including:

[0124] S1301 responds to a trigger operation on the display device by controlling the display device to light up and display the control interface.

[0125] In one alternative embodiment, after the refrigerator is powered on, it enters a standby state. In this state, the refrigerator detects touch signals for the display device in real time. When a touch signal for the display device is detected, the refrigerator controls the display device to light up and display the control interface in response to a trigger operation on the display device.

[0126] In one alternative embodiment, after the refrigerator is powered on, it enters a standby state. In this state, the refrigerator detects touch signals for the display device in real time. When a touch signal for the display device is detected, in response to a trigger operation for the display device, the side-inlet light guide component is controlled to light up, and the touch display component is controlled to display the control interface.

[0127] In the above embodiments, in response to a trigger operation on the display device, the controller synchronously controls the side-inlet light guide component to light up and provide backlight illumination to the display area, while simultaneously controlling the touch display component to display the control interface. This achieves instant linkage between user operation and visual feedback, allowing users to obtain a clear and bright interface response the moment they touch the display area, resulting in a smooth and lag-free interactive experience. By binding the backlight illumination and display content to the same trigger condition, energy waste caused by the light guide component being ineffectively lit for extended periods is avoided, reducing the overall power consumption of the device. The side-inlet light guide component only provides backlight to the display area, while the touch display component only displays the control interface when triggered. Both remain closed when not triggered, resulting in a pure white panel effect on the refrigerator door when the screen is off, enhancing the high-end feel of the product.

[0128] S1302 If no trigger operation is detected for the control interface within the preset time period, the control display device is turned off.

[0129] In one optional embodiment, during the user's touch operation on the control interface, the touch signal is detected in real time; if a continuous touch signal is detected, it is determined that the user is using the control interface; if no touch signal is detected, it is determined that the user is not using the control interface temporarily, and if no trigger operation for the control interface is detected within a preset time, the control display device is turned off.

[0130] In one optional embodiment, during the user's touch operation on the control interface, the touch signal is detected in real time; if a continuous touch signal is detected, it is determined that the user is using the control interface; if no touch signal is detected, it is determined that the user is not using the control interface temporarily. If no trigger operation for the control interface is detected within a preset time, the side-inlet light guide component is turned off, and the touch display component is turned off to display the control interface.

[0131] In the above embodiments, the backlight and display output can be cut off promptly after the interaction without manual operation by the user, effectively avoiding continuous power consumption caused by the user forgetting to turn them off, and significantly reducing the standby power consumption of the refrigerator as a whole. The synchronous shutdown of the light guide component and the display interface makes the display area completely hidden in the screen-off state. Combined with the structural design of the white light-transmitting panel and the light-shielding isolation dam, the display area presents a uniform appearance color with other areas of the door, completely eliminating the defects of traditional display panels that still leave traces or color differences after the screen is off, restoring the clean and integrated visual effect of the refrigerator door. The automatic shutdown mechanism reduces the ineffective working time of the display device and the light guide component, reduces the cumulative lighting time of the LED light-emitting unit and the touch display module, thereby delaying the decay of the light source and the aging of components, which helps to extend the overall service life and reliability of the display device.

[0132] In the above embodiments, by setting a light-shielding isolation dam around the display area on the inner side of the light-transmitting panel, an independent optical space is defined for the display device in terms of physical structure. This effectively blocks the diffusion of side-entered light into the non-display area, fundamentally avoiding halo and crosstalk problems at the edge of the display area. This ensures that the icon boundaries are clear and sharp when lit, and that it still has high recognizability in strong light environments. The light-shielding isolation dam, combined with the uniform appearance of the light-transmitting panel in the off state, makes the display area visually integrated with other areas of the door when closed, completely eliminating the abrupt color blocks of traditional black display solutions and significantly improving the overall aesthetics and high-end texture of the door. On this basis, the display device is lit synchronously in response to the trigger operation and automatically turned off after a preset time of no operation, realizing an intelligent interactive experience of display on demand. The power consumption of the whole machine is reduced by timely power-off. It does not rely on expensive materials such as electrochromic coatings or complex optical structures. It can achieve a comprehensive effect of unified appearance, clear display, and controllable cost through simple and reliable physical isolation and control logic.
