Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a display panel, a display system, and a household appliance. Background Technology

[0002] In modern home appliances, the widespread adoption of smart control technology has made touch panels an indispensable part of them. Touch panels not only improve the ease of operation of home appliances but also provide users with a more intuitive and richer interactive experience.

[0003] Most existing home appliance touch panels use an LED (Light Emitting Diode) screen combined with LED buttons. The LED screen can clearly display various information, such as time, temperature, and mode, while the LED buttons are used to execute specific operation commands. However, in this design, the LED buttons usually exist as independent elements on the screen, and their color and brightness often contrast with the screen background, which may visually disrupt the overall aesthetics of the screen.

[0004] Besides the aforementioned LED button solutions, full touchscreen designs are gradually emerging. However, this design also brings new problems. Full touchscreens are relatively expensive, increasing the manufacturing cost and selling price of home appliances. Furthermore, because touchscreens rely on complex circuitry and sensors to achieve touch functionality, their failure rate may also be relatively high. In addition, full touchscreens are prone to accidental touches, leading to operational errors and inconvenience for users. Utility Model Content

[0005] One object of the present invention is to provide an improved display panel, display system, and home appliance.

[0006] Therefore, this utility model embodiment provides a display panel including a first light-emitting layer and a second light-emitting layer stacked together. The first light-emitting layer is located on the side of the second light-emitting layer facing the light emission direction, wherein the first light-emitting layer is configured to emit light in response to a control command; the second light-emitting layer is used to display a target image, and at least a portion of the light emitted by the second light-emitting layer passes through the first light-emitting layer along the light emission direction.

[0007] Thus, the first light-emitting layer emits light in response to control commands, while the second light-emitting layer displays the target image, and at least a portion of the light emitted by the second light-emitting layer is visible to the outside through the first light-emitting layer. This layered structure enables the organic integration of functional prompts and target image display. Without affecting the integrity of the target image, it provides operational feedback to the user through luminous prompts, improving the functionality and aesthetics of the display panel, reducing the structural complexity of the display panel, and lowering manufacturing costs.

[0008] Optionally, the first light-emitting layer includes at least one light-emitting unit, and the display panel further includes at least one touch unit, corresponding one-to-one with the at least one light-emitting unit. The touch unit is used to receive the control command, and the light-emitting unit is configured to emit light in response to the corresponding touch unit receiving the control command. Thus, when the user touches the display panel and inputs a control command, the corresponding light-emitting unit emits light, effectively enhancing the interactivity between the user and the display panel, making the user's operation more intuitive and convenient.

[0009] Optionally, the projection of each light-emitting unit and the projection of the corresponding touch unit at least partially overlap. Thus, when a user inputs a control command by touching the display panel, the light-emitting unit in the corresponding area illuminates, indicating to the user that the corresponding control command has been successfully input, enhancing the interactivity of the display panel and improving the user experience.

[0010] Optionally, in the opposite direction to the light emission direction, the projection of each light-emitting unit is located within the area of ​​the second light-emitting layer used to present the target image. This allows for the simultaneous display of the target image and corresponding control prompts within the same display area, facilitating the miniaturization of the display panel and enhancing visual integrity.

[0011] Optionally, the target screen is associated with the touch unit that receives the control command among the at least one touch unit. This ensures a close correlation between the illuminated prompt, the touch operation, and the target screen, allowing the user to more clearly understand the correspondence between the operation and the feedback, thus improving the accuracy and efficiency of the operation.

[0012] Optionally, the display panel further includes a substrate made of a light-transmitting material, with the touch unit disposed on the side of the substrate facing the light-emitting direction. Thus, the light-transmitting substrate ensures complete display of the target image while providing a stable mounting base for the touch unit, resulting in a more compact and rational structure for the display panel, which helps reduce costs and improve production efficiency.

[0013] Optionally, the transmittance of the substrate is taken as [30%, 50%]. Thus, when the light-emitting unit emits light in response to the corresponding control command, the substrate with a transmittance of 30% to 50% can provide a backplate for the light-emitting unit, blocking part of the light emitted by the second light-emitting layer, making the light emitted by the light-emitting unit easier for the user to observe, and preventing the light of the light-emitting unit from being blocked by the light emitted by the second light-emitting layer, which would make it difficult for the user to observe the corresponding control command prompt light.

[0014] Optionally, the light-emitting unit includes: a first electrode portion and a second electrode portion disposed opposite to each other along the light-emitting direction, wherein the second electrode portion is located on the side of the first electrode portion facing the light-emitting direction; and a light-emitting portion located between the first electrode portion and the second electrode portion, the light-emitting portion being used to emit light under the action of the electric field generated by the first electrode portion and the second electrode portion. Thus, the light-emitting unit can employ the principle of electroluminescence, with the light-emitting portion emitting light under the action of the electric field formed between the first electrode portion and the second electrode portion. The electroluminescent material (e.g., the first electrode portion, the second electrode portion, and the light-emitting portion) can adopt a thin-film structure, allowing the display panel employing the electroluminescence principle to be made thinner and lighter, facilitating integration into various household appliances and contributing to improved overall product aesthetics and portability.

[0015] Optionally, the first electrode portion and the second electrode portion are made of a light-transmitting material. Therefore, the light-emitting unit does not affect the integrity of the target image; whether in a luminous or non-luminous state, the target image located on the side of the light-emitting unit opposite to the light-emitting direction can be fully observed by the user.

[0016] Optionally, the transmittance of the first electrode portion is lower than that of the second electrode portion. Therefore, the lower transmittance of the first electrode portion allows it to function as a backplate for the light-emitting portion when it emits light, making the light emitted by the light-emitting portion more noticeable and easily observed.

[0017] Optionally, the display panel further includes an icon layer, comprising at least one icon corresponding to each of the at least one light-emitting unit. Along the light emission direction, the projection of the icon and the projection of the corresponding light-emitting unit at least partially overlap. Thus, the icon layer provides users with intuitive operation instructions, allowing them to quickly identify the function of the light-emitting unit through the icons, reducing operational difficulty and improving the convenience and accuracy of operation.

[0018] Optionally, the display panel further includes a cover plate located on the side of the first light-emitting layer facing the light-emitting direction, and the icon layer disposed on one of the two opposite sides of the cover plate. Thus, the cover plate can protect other components of the display panel (e.g., the first and second light-emitting layers) from external scratches and impacts that could damage the internal components; the icon layer is disposed on the cover plate for easy observation and operation by the user, without affecting the overall aesthetics and performance of the display panel.

[0019] This utility model embodiment also provides a display system, including: the display panel described above; and a control module that communicates with the display panel. The control module is used to receive control commands and control the first light-emitting layer to emit light and / or the second light-emitting layer to display a corresponding target image according to the control commands.

[0020] Thus, the display system organically combines the display panel and control module, realizing intelligent control of the display panel, improving the overall performance and functional expandability of the display system, and meeting the needs of different application scenarios.

[0021] This utility model embodiment also provides a household appliance, including: a body; the aforementioned display panel disposed on the outer surface of the body; and a control module communicating with the display panel, wherein the control module is used to receive control commands and control the first light-emitting layer to emit light and / or the second light-emitting layer to display a corresponding target image according to the control commands.

[0022] This enhances the technological sophistication and aesthetics of home appliances, while providing users with a more convenient and intuitive way to operate them, thereby increasing user satisfaction.

[0023] Optionally, the home appliance also includes functional components, and the control module controls the operation of the functional components according to the control instructions. Thus, the display panel of the home appliance can not only provide information display and operational feedback, but also control the operation of the functional components, achieving a deep integration of display and function, further enhancing the intelligence level of the home appliance and the user experience.

Detailed Implementation

[0031] As mentioned in the background section, existing display panels have poor display effects, complex structures, and high manufacturing costs.

[0032] To solve at least one of the above-mentioned technical problems, this utility model provides a display panel, including a first light-emitting layer and a second light-emitting layer stacked together. The first light-emitting layer is located on the side of the second light-emitting layer facing the light emission direction, wherein the first light-emitting layer is configured to emit light in response to a control command; the second light-emitting layer is used to display a target image, and at least a portion of the light emitted by the second light-emitting layer passes through the first light-emitting layer along the light emission direction.

[0033] Thus, the first light-emitting layer emits light in response to control commands, while the second light-emitting layer displays the target image, and at least a portion of the light emitted by the second light-emitting layer is visible to the outside through the first light-emitting layer. This layered structure enables the organic integration of functional prompts and target image display. Without affecting the integrity of the target image, it provides operational feedback to the user through luminous prompts, improving the functionality and aesthetics of the display panel, reducing the structural complexity of the display panel, and lowering manufacturing costs.

[0034] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0035] Figure 1 This is a schematic diagram of a household appliance 100 according to an embodiment of the present utility model. Figure 2 yes Figure 1 A schematic diagram of the central display panel 10. Figure 3 yes Figure 2 The structure shown is a cross-sectional view along the AA direction.

[0036] refer to Figure 1The home appliance 100 may include: a body 101; a display panel 10 disposed on the outer surface of the body 101; and a control module 20 communicating with the display panel 10. The control module 20 is used to receive control commands and, according to the control commands, control the first light-emitting layer 1 to emit light and / or the second light-emitting layer 2 to display the corresponding target image. This enhances the technological feel and aesthetics of the home appliance 100, while providing users with a more convenient and intuitive operating method, thereby increasing user satisfaction with the home appliance 100.

[0037] In some embodiments, the household appliance 100 may integrate electrical components to achieve corresponding functions. For example, the household appliance 100 may include a washing machine, washer-dryer, dryer, refrigerator, air conditioner, etc.

[0038] In some embodiments, the household appliance 100 may be, for example, a washing machine, washer-dryer, or dryer. The household appliance 100 may include a body 101. In some embodiments, the body 101 may include a drum 40 for holding objects to be washed and / or dried. Furthermore, the body 101 may also be provided with a detergent dispenser 40 for dispensing detergent into the drum 40. The detergent dispenser 40 may be, for example, a drawer-type dispenser.

[0039] Furthermore, the home appliance 100 may also include a functional component 30, and the control module 20 controls the operation of the functional component 30 according to the control instructions. Thus, the display panel 10 of the home appliance 100 can not only provide information display and operation feedback, but also control the operation of the functional component 30, achieving a deep integration of display and function, further enhancing the intelligence level and user experience of the home appliance 100.

[0040] In some embodiments, the functional component 30 may include a drying module to enable the drying function of the household appliance 100.

[0041] In other embodiments, functional component 30 may also include a temperature control module that can heat the washing water to different temperatures to achieve different washing functions. Alternatively, functional component 30 may also include a motor for driving the roller 30 to rotate.

[0042] In some embodiments, the roller 40 may have a forward-facing opening for a user to place or retrieve objects into the roller 40. In some embodiments, the feed box 20 may move along the y-direction toward or away from the body 10 to be pulled out or pushed back into the body 10.

[0043] Combination Figures 1 to 3In some embodiments, the display panel 10 may include a first light-emitting layer 1 and a second light-emitting layer 2 stacked together. The first light-emitting layer 1 is located on the side of the second light-emitting layer 2 facing the light-emitting direction, wherein the first light-emitting layer 1 is configured to emit light in response to a control command; the second light-emitting layer 2 is used to display a target image, and at least a portion of the light emitted by the second light-emitting layer 2 passes through the first light-emitting layer 1 along the light-emitting direction. Thus, the first light-emitting layer 1 emits light in response to a control command, and the second light-emitting layer 2 displays the target image while at least a portion of its emitted light passes through the first light-emitting layer 1. This stacked structure enables the organic combination of functional prompts and target image display. Without affecting the integrity of the target image, it can provide operational feedback to the user through luminous prompts, improving the functionality and aesthetics of the display panel 10, while reducing the structural complexity of the display panel 10 and lowering manufacturing costs.

[0044] Specifically, the first light-emitting layer 1 and the second light-emitting layer 2 are arranged in a stacked manner, with the first light-emitting layer 1 located on the side of the second light-emitting layer 2 facing the light-emitting direction. That is, the first light-emitting layer 1 is closer to the outer surface of the household appliance 100 than the second light-emitting layer 2. This stacked structure allows the two light-emitting layers to overlap in space, but each performs different functions, achieving an organic combination of functions through a reasonable layout.

[0045] Furthermore, the first light-emitting layer 1 can emit light in response to control commands. For example, when a user inputs a control command to the display panel 10 in some way (such as through touch operation), the first light-emitting layer 1 can emit light accordingly based on the control command. For instance, when the household appliance 100 is a washing machine, when the user selects a washing or drying program, the corresponding first light-emitting layer 1 can emit light to indicate to the user that the operation has been recognized. Thus, this light-emitting prompt function provides the user with intuitive operational feedback, allowing the user to clearly know whether their operation has been successful. This enhances the interactivity between the user and the display panel 10 and improves the user experience. At the same time, compared to traditional methods of providing prompts through sound or text, light-emitting prompts are more intuitive and eye-catching, especially in noisy environments, where users can easily obtain operational feedback information.

[0046] Furthermore, the main function of the second light-emitting layer 2 is to display target images, which can contain various information such as time, temperature, the operating status of the appliance, and selectable operating modes. For example, when the display panel 10 is applied to a refrigerator, the second light-emitting layer 2 can display information such as the current refrigerator compartment temperature, freezer compartment temperature, and the set target temperature. Or, when the display panel 10 is applied to a washing machine or washer-dryer, the target image displayed by the second light-emitting layer 2 can be related to the currently executing function program. For example, when the washing machine or washer-dryer is executing a washing program, the target image can display images such as waves.

[0047] In some embodiments, the second light-emitting layer 2 may include a circuit board 21 and a pixel array 22 disposed on the side of the circuit board 21 facing the light-emitting direction, such as an LED lamp bead array.

[0048] Furthermore, at least a portion of the light emitted by the second light-emitting layer 2 can pass through the first light-emitting layer 1 along the light emission direction. This ensures that the first light-emitting layer 1 and the light emitted by it do not affect the integrity of the target image display. For example, when the first light-emitting layer 1 emits light, its light will not completely block the image displayed by the second light-emitting layer 2; the user can still clearly see the image content while simultaneously receiving the illumination prompts from the first light-emitting layer 1, achieving a perfect combination of functional prompts and target image display. This satisfies the basic information display requirements of the display panel 10 while providing additional operational feedback to the user through the illumination function of the first light-emitting layer 1, enhancing the functionality and aesthetics of the display panel 10. At the same time, the stacked arrangement of the first and second light-emitting layers reduces the use of independent components, lowers the structural complexity of the display panel 10, and helps reduce manufacturing costs.

[0049] In some embodiments, combined with Figure 2 and Figure 3 The first light-emitting layer 1 includes at least one light-emitting unit 11, and the display panel further includes at least one touch unit 3, corresponding one-to-one with the at least one light-emitting unit 11. The touch unit 3 is used to receive the control command, and the light-emitting unit 11 is configured to emit light in response to the corresponding touch unit 3 receiving the control command. Thus, when the user touches the display panel 10 and inputs a control command, the corresponding light-emitting unit 11 emits light, effectively enhancing the interactivity between the user and the display panel 10, making the user's operation more intuitive and convenient. The touch unit 3 can be a capacitive touch layer made of a transparent conductive material.

[0050] Specifically, the first light-emitting layer 1 is composed of at least one light-emitting unit 11. In other words, the first light-emitting layer 1 is not a single, integrated light-emitting structure, but is composed of at least one independent light-emitting unit 11. Each light-emitting unit 11 has independent light-emitting capability, and its light-emitting state can be controlled individually as needed.

[0051] In some embodiments, the first light-emitting layer 1 may include a plurality of light-emitting units 11, which can be filled and bonded together by materials such as optically transparent adhesive to form a layer structure. The plurality of light-emitting units 11 may be arranged in an array in a plane perpendicular to the light emission direction to form the first light-emitting layer 1.

[0052] In a specific implementation scenario, different light-emitting units 11 can emit light of different colors, brightnesses, or flashing frequencies according to different control commands, thereby achieving a variety of complex lighting prompt effects. For example, when the display panel 10 is applied to a smart air conditioner, different light-emitting units 11 can correspond to different temperature adjustment levels. When the user adjusts the temperature, the corresponding light-emitting unit 11 will light up to indicate the currently selected level.

[0053] Furthermore, the display panel 10 may also include at least one touch unit 3, and these touch units 3 correspond one-to-one with the light-emitting units 11. That is, each light-emitting unit 11 has a corresponding touch unit 3. In this scenario, the light-emitting state of the light-emitting unit 22 is closely related to the control command received by the corresponding touch unit 22. When the touch unit 22 receives the user's control command, the light-emitting unit 22 will make a corresponding light-emitting response according to the command. This correspondence ensures that when the user operates a certain touch unit 3, the light-emitting state of the corresponding light-emitting unit 11 can be accurately controlled, thereby providing feedback to the user on the reception status of the control command. For example, if the user touches a certain touch unit 3, the corresponding light-emitting unit 11 may light up immediately, or light up according to a preset light-emitting mode (such as flashing, color changing, etc.).

[0054] In some embodiments, along the light emission direction, the projection of each light-emitting unit 11 and the projection of the corresponding touch unit 3 at least partially overlap. Therefore, when a user inputs a control command by touching the display panel 10, the light-emitting unit 11 in the corresponding area illuminates, indicating to the user that the corresponding control command has been successfully input, enhancing the interactivity of the display panel 10 and improving the user experience.

[0055] From a user's perspective, when a user inputs control commands on the touch display panel 10, the projections of the light-emitting unit 11 and the touch unit 3 at least partially overlap, allowing the user to more intuitively perceive the correspondence between the touch operation and the illuminated prompts. For example, when a user wants to select a function, they only need to touch the area where the projections of the light-emitting unit 11 and the touch unit 3 overlap to accurately input the control command and clearly see the corresponding light-emitting unit 11 illuminate, thus confirming their operation and improving the efficiency and accuracy of the interaction between the user and the display panel 10.

[0056] In some embodiments, the projection of each light-emitting unit 11 is located in the area of ​​the second light-emitting layer 2 used to present the target image, in the opposite direction to the light-emitting direction. Therefore, the target image and the corresponding instruction prompts can be displayed simultaneously in the same display area, which is beneficial for miniaturizing the display panel 10 and improving the overall visual appeal.

[0057] In practice, users can simultaneously obtain target screen information and operation feedback information within the same display area. While observing the target screen, users can intuitively see the illuminated prompts of the light-emitting unit 11, eliminating the need to switch their gaze between different areas, making operation more convenient and efficient. For example, on washing machines or washer-dryers, users can quickly understand the current operating status, such as washing time and water level, through the illuminated prompts of the light-emitting unit 11 while viewing the washing program display screen, thus improving user satisfaction with the operation of the home appliance 100.

[0058] In some embodiments, the target screen is associated with the touch unit 3 that receives the control command. This ensures a close correlation between the illuminated prompt, the touch operation, and the target screen, allowing the user to more clearly understand the correspondence between the operation and the feedback, thus improving the accuracy and efficiency of the operation.

[0059] In practical applications, when a user operates the touch unit 3 on the display panel 10 and inputs a control command, the display panel will display the corresponding target image on the second light-emitting layer 2 according to the command. That is to say, different touch units 3 will trigger the display of different target images after receiving control commands, or make different adjustments to the same target image.

[0060] In some embodiments, combined with Figures 3 to 5 The display panel 10 may further include a substrate 4 made of a light-transmitting material, such as a PET substrate, with the touch unit 3 disposed on the side of the substrate 4 facing the light-emitting direction. Thus, the light-transmitting substrate ensures complete display of the target image while providing a stable mounting base for the touch unit 3, making the structure of the display panel 10 more compact and rational, which helps reduce costs and improve production efficiency. The capacitive touch layer can be applied to the substrate 4 using a printing process.

[0061] In some embodiments, the substrate 4 is located between the first light-emitting layer 1 and the second light-emitting layer 2. Furthermore, the light emitted from the second light-emitting layer 2 can pass through the substrate 4.

[0062] In some embodiments, the substrate 4 may be, for example, a touchpad that carries the touch unit 3.

[0063] In some embodiments, the transmittance of the substrate 4 is taken from [30%, 50%]. Therefore, when the light-emitting unit 11 emits light in response to the corresponding control command, the substrate 4 with a transmittance of 30%~50% can balance the brightness of the light emitted from the second light-emitting layer 2 on the outer surface of the household appliance 100 and the brightness of the light emitted from the light-emitting unit 11 on the outer surface of the household appliance 100, optimizing the display effect when the target image and icon 51 are superimposed. This avoids the light emitted from the target image being too bright, causing the light-emitting unit 11 to be obscured by the light emitted from the target image, ensuring that the user can clearly observe the corresponding control command prompt light.

[0064] Specifically, transmittance refers to the ratio of transmitted light intensity to incident light intensity when light passes through a material, usually expressed as a percentage. In the display panel 10 described in this embodiment, the transmittance of the substrate 4 reflects the ability of light to pass through the substrate 4, that is, the proportion of light emitted from the second light-emitting layer 2 that can pass smoothly through the substrate 4. By setting the transmittance of the substrate 4 to below 50%, some of the light from the second light-emitting layer 2 can be blocked inside the household appliance 100, preventing the brightness of the target image displayed on the outer surface of the household appliance 100 from being too high, making it difficult for the user to see the illuminated icon 51 of the light-emitting unit 11. By controlling the transmittance of the substrate 4 to be no less than 30%, it is ensured that the second light-emitting layer 2 still has enough light to pass through the first light-emitting layer 1 to reach the outer surface of the household appliance 100, ensuring the visibility of the target image.

[0065] Furthermore, the surface of the substrate 4 can reflect the light emitted by the light-emitting unit 11 away from the light-emitting direction to a certain extent, causing more light to propagate in the light-emitting direction and increasing the amount of light emitted by the light-emitting unit 11 towards the user. Furthermore, the substrate 4 can also enhance the contrast between the light emitted by the light-emitting unit 11 and the surrounding environment (mainly the light emitted by the target image).

[0066] Continue to refer to Figure 4 and Figure 5In some embodiments, the light-emitting unit 11 may include: a first electrode portion 111 and a second electrode portion 112 disposed opposite to each other along the light-emitting direction, wherein the second electrode portion 112 is located on the side of the first electrode portion 111 facing the light-emitting direction; and a light-emitting portion 113 located between the first electrode portion 111 and the second electrode portion 112, the light-emitting portion 113 being used to emit light under the action of the electric field generated by the first electrode portion 111 and the second electrode portion 112. Thus, the light-emitting unit 11 can employ the principle of electroluminescence, causing the light-emitting portion 113 to emit light under the action of the electric field formed between the first electrode portion 111 and the second electrode portion 112. The electroluminescent material (e.g., the first electrode portion 111, the second electrode portion 112, and the light-emitting portion 113) can employ a thin-film structure, allowing the display panel 10 employing the electroluminescence principle to be made thinner and lighter, facilitating integration into various household appliances and contributing to improved overall product aesthetics and portability.

[0067] In some embodiments, the light-emitting unit 11 may employ the principle of electroluminescence, utilizing the electric field formed between the first electrode portion 111 and the second electrode portion 112 to excite the light-emitting portion 113 to emit light. The light-emitting portion 113 may be made of a material with light-emitting properties, such as organic light-emitting materials or quantum dot materials. When an appropriate voltage is applied between the first electrode portion 111 and the second electrode portion 112, an electric field is generated between them. This electric field causes electrons and holes in the light-emitting portion 113 to move directionally and recombine within the light-emitting portion 113. When electrons and holes recombine, energy is released, and this energy is radiated in the form of photons, thereby achieving light emission.

[0068] In some embodiments, the first electrode portion 111 may be, for example, the cathode of the electroluminescent system, and the second electrode portion 112 may be, for example, the anode of the electroluminescent system. Alternatively, the second electrode portion 112 may be, for example, the cathode of the electroluminescent system, and the first electrode portion 111 may be, for example, the anode of the electroluminescent system.

[0069] In some embodiments, the luminous intensity and color of the light-emitting portion 113 can be precisely controlled by controlling the magnitude and polarity of the voltage applied between the first electrode portion 111 and the second electrode portion 112. Different light-emitting materials have different response characteristics to electric fields. By selecting appropriate light-emitting materials and adjusting voltage parameters, various luminous effects with different colors and brightness can be achieved to meet the diverse display needs of the display panel 10.

[0070] In some embodiments, the first electrode portion 111, the second electrode portion 112, and the light-emitting portion 113 can be made into thin-film structures. Thin-film structures have a smaller thickness and weight, which can significantly reduce the overall volume and weight of the display panel 10 compared to conventional bulk materials.

[0071] In terms of manufacturing processes, the fabrication processes for the thin film structures of the first electrode portion 111, the second electrode portion 112, and the light-emitting portion 113 are relatively mature. Various thin film deposition techniques, such as physical vapor deposition (PVD) and chemical vapor deposition (CVD), can be employed to produce uniform and dense thin films. These processes offer high production efficiency and good repeatability, ensuring the quality and performance of the first electrode portion 111, the second electrode portion 112, and the light-emitting portion 113. This facilitates large-scale production and reduces production costs.

[0072] In some embodiments, the first electrode portion 111 and the second electrode portion 112 are made of a light-transmitting material. Therefore, the light-emitting unit 11 does not affect the integrity of the target image; whether in a light-emitting state or a non-light-emitting state, the target image located on the side of the light-emitting unit 11 facing away from the light-emitting direction can be fully observed by the user.

[0073] In some embodiments, the light-transmitting material used to fabricate the first electrode portion 111 and the second electrode portion 112 needs to possess good electrical properties while ensuring light transmittance. For example, the transparent material can be indium tin oxide (ITO). Indium tin oxide has both high light transmittance (typically above 80%) and good conductivity, enabling the formation of the required electric field between the first electrode portion 111 and the second electrode portion 112. Thus, the light-emitting portion 113 can operate normally under the influence of the electric field, achieving its light-emitting function.

[0074] In some embodiments, the transmittance of the first electrode portion 111 is lower than that of the second electrode portion 112. Therefore, because the first electrode portion 111 has lower transmittance, when the light-emitting portion 113, located between the first electrode portion 111 and the second electrode portion 112 along the light emission direction, emits light, the first electrode portion 111, with its lower transmittance, can serve as a backplate for the light-emitting portion 113, making the light emitted by the light-emitting portion 113 more noticeable and easily observed.

[0075] In some embodiments, the display panel 10 may further include an icon layer 5, comprising at least one icon 51 corresponding to one of the at least one light-emitting unit 11, wherein the projection of the icon 51 and the projection of the corresponding light-emitting unit 11 at least partially overlap along the light-emitting direction. Thus, the icon layer 5 provides users with intuitive operation instructions, allowing them to quickly identify the function corresponding to the touch area through the icon 51, reducing the difficulty of operation and improving the convenience and accuracy of operation.

[0076] In some embodiments, the icon layer 5, the light-emitting unit 11, and the touch unit 3 can be disposed on a single substrate 4 through a printing process. For example, the light-emitting unit 11 is an electroluminescent layer and the touch unit 3 is a capacitive touch layer. The capacitive touch layer can be printed first, followed by the electroluminescent layer, and finally the icon layer 5. Alternatively, the printing order of the three components can be adjusted by modifying the printing process.

[0077] In some embodiments, the display panel 10 may further include: a cover plate 6 located on the side of the first light-emitting layer 1 facing the light-emitting direction, and the icon layer 5 disposed on one of the two opposite sides of the cover plate 6. Thus, the cover plate 6 can protect other components of the display panel 10 (e.g., the first light-emitting layer 1 and the second light-emitting layer 2) from external scratches and impacts that could damage the internal components; the icon layer 5 is disposed on the cover plate for easy observation and operation by the user, without affecting the overall aesthetics and performance of the display panel.

[0078] refer to Figure 5 This application also provides a display system, including: as described above. Figures 1 to 4 The display panel 10 is shown in the embodiment or similar embodiments. The display system also includes a control module 20, which communicates with the display panel 10. The control module 20 is used to receive control commands and control the first light-emitting layer 1 to emit light and / or the second light-emitting layer 2 to display the corresponding target image according to the control commands.

[0079] Thus, the display system organically combines the display panel 10 and the control module 20, realizing intelligent control of the display panel 10, improving the overall performance and functional expandability of the display system, and meeting the needs of different application scenarios.

[0080] The control module 20 can be a microcontroller of the home appliance 100, or it can be a control unit in the home appliance 100 specifically used to implement the display function.
