Description

Technical Field

[0001] The utility model relates to the technical field of display control, in particular to a display screen and a household appliance. Background Art

[0002] With the trend toward smarter and more advanced home appliances, innovative metal panel display control technologies with interactive sliding functionality will be increasingly widely used in these products. Currently, there are two approaches to implementing this metal panel display control technology. The first involves hollowing out a window area in a stainless steel panel and filling it with a light-transmitting material to achieve the desired display function. However, this approach not only compromises the consistency and integrity of the stainless steel panel, but also increases the number of product components, and complicates assembly between stainless steel and other materials. The second approach involves laser-engraving icons into the stainless steel panel to enable mechanical operation. However, due to the limitations of metal's conductive properties and its non-transparent nature, this approach cannot achieve interactive sliding display functionality, and can only implement simple mechanical button functions.

[0044] See also Figure 1 and Figure 2 , an embodiment of the present invention provides a display screen 100. The display screen 100 includes a display assembly, which includes a metal panel 10, an infrared touch layer 30, a light source board 50 and a control assembly 60. The metal panel 10, the infrared touch layer 30 and the light source board 50 are arranged in sequence along the thickness direction of the display assembly, and the control assembly 60 is electrically connected to the infrared touch layer 30 and the light source board 50. The metal panel 10 is provided with a display interaction area 101, and the metal panel 10 is provided with a plurality of light-transmitting holes 103 in the display interaction area 101. The light source board 50 includes a light-emitting area 501, which corresponds to the display interaction area 101 in the thickness direction of the display assembly. The infrared touch layer 30 is used to detect touch gestures in the display interaction area 101. The control assembly 60 is used to control the light-emitting area 501 to emit light according to the touch gesture so that the light emitted by the light-emitting area 501 is emitted from the light-transmitting hole 103.

[0045] In the above-mentioned display screen 100, the metal panel 10 is used as the interactive medium. The control component 60 can control the light source panel 50 to emit light according to the touch gesture detected by the infrared touch layer 30, and the light is emitted from the light-transmitting hole 103 opened in the metal panel 10, thereby realizing the touch interactive function of the display component.

[0046] Specifically, please combine Figure 1 and Figure 4The home appliance 200 may be provided with a display screen 100 having a sliding interaction function. The display screen 100 includes a display component, which includes a metal panel 10. Users can operate the metal panel 10 through touch gestures. For example, the home appliance 200 can be controlled and input through simple touch, sliding, single or double-clicking actions, without having to find and press physical buttons. This provides a smooth operating experience, reduces operating steps and time, and improves usage efficiency.

[0047] In related technologies, there are two approaches to implementing metal panel display control technology. The first approach involves hollowing out a window area on a stainless steel panel and filling it with a light-transmitting material to achieve the desired display effect. However, this approach not only compromises the consistency and integrity of the stainless steel panel, but also increases the number of product components, and the assembly of stainless steel and other materials is more complex. The second approach involves laser-engraving icons on the stainless steel panel to enable mechanical operation. However, due to the limitations of metal's conductive properties and its non-transparent nature, this approach cannot achieve interactive sliding display functionality, and can only implement simple mechanical button functions.

[0048] Please combine Figure 2 The thickness of the display assembly is the front-to-back direction. The metal panel 10, infrared touch layer 30, and light source board 50 are arranged sequentially along the front-to-back direction, with the front surface of the metal panel 10 facing the user's operating direction. A display interaction area 101 is defined on the front surface of the metal panel 10. Optionally, a plurality of light-transmitting holes 103 are formed in the display interaction area 101 by methods including, but not limited to, micro-hole etching.

[0049] The light source board 50 is located behind the infrared touch layer 30. The light emitting area 501 provided on the light source board 50 corresponds to the display interaction area 101 on the metal panel 10 in the thickness direction of the display component, so that the light emitted by the light emitting area 501 can be emitted through the light-transmitting hole 103 on the display interaction area 101. Optionally, the light source board 50 may be a dot matrix light source board 50, and the light source board 50 may include a plurality of light emitting parts, and the plurality of light emitting parts may include red light emitting diodes (LEDs), green light emitting diodes and blue light emitting diodes. Multiple light emitting parts can be arranged into a light emitting array. The light source board 50 can provide rich color and brightness adjustment, making the displayed content more vivid and colorful, and to a certain extent meeting the visual needs of different application scenarios. At the same time, the dot matrix layout also allows the display component to independently control each LED, thereby achieving more sophisticated image display and dynamic effects.

[0050] The infrared touch layer 30 is disposed between the metal panel 10 and the light source panel 50. Optionally, the infrared touch layer 30 includes a transmitter and a receiver. The receiver may include an infrared light sensor. The transmitter may include, but is not limited to, an infrared LED lamp, which can emit infrared light, allowing the infrared light to be emitted through the light-transmitting holes 103 in the display interaction area 101. When a user performs a touch gesture on the metal panel 10, the gesture enters the path of the infrared beam, reflecting a portion of the emitted infrared light. The receiver may include, but is not limited to, an infrared photodiode or a phototransistor, which can receive the reflected infrared light, detect the intensity and angle changes of the reflected light, and convert the reflected light into different electrical signals for transmission to the control component 60.

[0051] The control component 60 is electrically connected to the light source panel 50 and the infrared touch layer 30, respectively. The receiver of the infrared touch layer 30 receives the reflected infrared light and converts it into different electrical signals based on the intensity and angle of the reflected light. These signals are then transmitted to the control component 60. After receiving the electrical signals, the control component 60 controls the light-emitting area 501 on the light source panel 50 to illuminate based on the touch gesture information detected by the infrared touch layer 30, thereby enabling dynamic updates and interactive feedback to the user interface. Optionally, the control component 60 can control the light intensity, color, and area of ​​the light-emitting area 501, so that the display interaction area 101 forms different display images or indication content in different application scenarios.

[0052] In summary, using the metal panel 10 as the interactive medium, the control component 60 can control the light source panel 50 to emit light based on the touch gestures detected by the infrared touch layer 30. Light emitted by the light source panel 50 is emitted through the light-transmitting holes 103 defined in the metal panel 10, thereby enabling the touch-sensitive interactive function of the display component. The display control technology of the metal panel 10's microporous light transmission ensures a certain degree of consistency in the product's appearance and enhances the product's intelligent experience.

[0053] The shape of the light-transmitting hole 103 can be specifically limited according to actual conditions, and the present invention does not make any specific restrictions on this. In one example, the shape of the light-transmitting hole 103 can be circular, polygonal, or other regular or irregular shapes.

[0054] The shape of the display screen 100 can be specifically limited according to actual conditions, and the present invention does not impose any specific restrictions on this. In one example, the display screen 100 is in the shape of a cuboid.

[0055] In some embodiments, the plurality of light-transmitting holes 103 are arranged in an array.

[0056] In this way, the light-transmitting holes 103 arranged in a matrix manner can be easily processed and can constitute pixels equivalent to the display interactive area 101 .

[0057] Specifically, please combine Figure 1 and Figure 2 The metal panel 10 is provided with a plurality of light-transmitting holes 103 for allowing light emitted by the light-emitting area 501 of the light source panel 50 to pass through. Functionally equivalent to pixels in traditional display technology, these light-transmitting holes 103 can be used to display images or information. The plurality of light-transmitting holes 103 are arranged in an array, allowing for machining of the light-transmitting holes 103 in rows and columns according to the predetermined spacing between the light-transmitting holes 103, thereby improving machining efficiency.

[0058] The number of light-transmitting holes 103 can be specifically limited according to actual conditions, and the present invention does not impose any specific limitation thereon. The plurality of light-transmitting holes 103 can be arranged in an array of m (rows)*n (columns).

[0059] In some embodiments, the diameter of the light-transmitting hole 103 is no greater than the thickness of the metal panel 10 .

[0060] In this way, the light-transmitting holes 103 not only provide sufficient light to pass through, but also maintain the structural integrity and mechanical strength of the metal panel 10 to a certain extent.

[0061] Specifically, please combine Figure 3 Optionally, the light-transmitting hole 103 is circular. The thickness of the metal panel 10 is T, and the aperture of the light-transmitting hole 103 is D1. The aperture of the light-transmitting hole 103 is not greater than the thickness of the metal panel 10, that is, D1≤T. Therefore, this size relationship allows the light-transmitting hole 103 to provide sufficient light to pass through without weakening the structural stability of the metal panel 10. When the thickness of the metal panel 10 meets the structural strength, the human eye will not easily notice the existence of a single light-transmitting hole 103, providing a better visual experience. The specific values ​​of the aperture D1 of the light-transmitting hole 103 and the thickness T of the metal panel 10 can be specifically defined according to display requirements and manufacturing processes, and the present invention does not make specific limitations on this.

[0062] In some embodiments, the distance between two adjacent light-transmitting holes 103 is equal to the aperture of the light-transmitting hole 103 .

[0063] In this way, the light emitted by the light source board 50 passes through the matrix of light-transmitting holes 103 on the metal panel 10 , allowing the light points of each light-transmitting hole 103 to visually diffuse and connect into a planar light image, providing an intuitive image display for the user.

[0064] Specifically, please combine Figure 3The aperture of light-transmitting hole 103 is D1, and the distance between two adjacent light-transmitting holes 103 is D2. The distance between two adjacent light-transmitting holes 103 is equal to the aperture of light-transmitting hole 103, that is, D1 = D2. Therefore, through the principle of microporous light transmission of metal panel 100, the light emitted by light source board 50 passes through the matrix of light-transmitting holes 103 on metal panel 10. The light emitted by each light-transmitting hole 103 can be integrated due to light diffusion, making the existence of light-transmitting holes 103 difficult for the human eye to identify. The light points of each light-transmitting hole 103 are visually diffused and connected to form a planar light image, providing the user with an intuitive image display.

[0065] The specific value of the distance D2 between two adjacent light-transmitting holes 103 can be specifically limited according to display requirements and manufacturing processes, and the present invention does not make any specific limitation on this.

[0066] In some embodiments, the control assembly 60 includes a circuit board and electronic components. The electronic components are disposed on a surface of the circuit board, and the circuit board is disposed on a side of the light source board 50 facing away from the infrared touch layer 30 .

[0067] In this way, the structure of the display screen 100 can be more compact.

[0068] Specifically, please combine Figure 2 The circuit board is located on the side of the light source board 50 facing away from the infrared touch layer 30, that is, the circuit board is located on the rear side of the light source board 50. The metal panel 10, infrared touch layer 30, light source board 50, and circuit board can be stacked together, thereby reducing the space occupied by the display screen 100 and making the display screen 100 more compact. The circuit board, light source board 50, and infrared touch layer 30 are electrically connected through, but not limited to, flexible circuits or electrical connectors, ensuring a certain degree of stability and flexibility in electrical signal transmission.

[0069] When the user operates the display interaction area 101 of the metal panel 10 through gestures, the infrared touch layer 30 transmits the detected touch gesture information of the user in the display interaction area 101 to the control component 60. The control component 60 controls the light-emitting area 501 on the light source panel 50 to emit light according to the touch gesture, so that the display component can provide display and interaction functions.

[0070] The control assembly 60 may include a circuit board and electronic components, which work together to achieve intelligent control of the display assembly. In one embodiment, the circuit board may include a PCB board, and the electronic components include but are not limited to a microcontroller, a driver chip, a sensor interface, etc., and the electronic components are arranged on the surface of the circuit board.

[0071] It is understandable that, in other embodiments, the circuit board may include other types of circuit boards, and the electronic components include but are not limited to control chips, capacitors, resistors, inductors and other components.

[0072] In some embodiments, the control component 60 is used to control the infrared touch layer 30 and the light source panel 50 to emit light alternately.

[0073] In this way, the control component 60 controls the light source panel 50 to emit light according to the touch gesture detected by the infrared touch layer 30, thereby realizing dynamic update and interactive feedback of the user interface.

[0074] Specifically, the control component 60 controls the infrared touch layer 30's light emitter to emit infrared light. When a user performs gestures in the display interaction area 101 of the metal panel 10, the gesture enters the infrared beam's path, reflecting some of the emitted infrared light. The infrared touch layer 30's receiver receives this reflected light and converts it into different electrical signals based on the intensity and angle of the reflected light. The signals are then transmitted to the control component 60. After receiving the electrical signals, the control component 60 controls the light-emitting area 501 on the light source panel 50 to illuminate based on the touch gesture detected by the infrared touch layer 30, enabling dynamic updates and interactive feedback for the user interface.

[0075] Therefore, the user's touch gestures can be accurately recognized and quickly responded to, which improves the user experience to a certain extent.

[0076] In some embodiments, the display assembly includes a light shielding layer 40 , which is disposed between the light source panel 50 and the infrared touch layer 30 .

[0077] In this way, the light emitted by the light source panel 50 is directed directly, which reduces the astigmatism and halo phenomena to a certain extent.

[0078] Specifically, please combine Figure 2 The light shielding layer 40 is located between the light source panel 50 and the infrared touch layer 30. Optionally, the two sides of the light shielding layer 40 can be adhered to the light source panel 50 and the infrared touch layer 30, respectively, using double-sided tape. Light emitted from the light emitting area 501 of the light source panel 50 is emitted through the light shielding layer 40. The light shielding layer 40 effectively blocks indirect light, thereby reducing scattered light and haloing to a certain extent. This makes the display effect of the display interaction area 101 clearer when illuminated, providing users with a better visual experience.

[0079] Optionally, the light shielding layer 40 is configured to be ultra-thin, ultra-bright, uniformly conduct light, and be energy-efficient and environmentally friendly. The material of the light shielding layer 40 can be specifically limited according to actual conditions, and this utility model does not impose specific restrictions on this. In one example, the light shielding layer 40 can be a transparent material such as an acrylic plate or a polycarbonate (PC) plate.

[0080] In some embodiments, the metal panel 10 is provided with an icon hole 105 , and the icon hole 105 is located on a side of the display interaction area 101 .

[0081] In this way, simple and intuitive operation navigation and guidance can be provided to users.

[0082] Specifically, please combine Figure 1 and Figure 2 The icon holes 105 are provided on both sides of the display interaction area 101, which can provide users with simple and intuitive operation navigation and guidance, so that users can easily find and activate the required functions. When the user touches the icon hole 105, part of the infrared light emitted by the emitter of the infrared touch layer 30 will be reflected. The receiver of the infrared touch layer 30 receives these reflected lights and converts them into different electrical signals according to the intensity and angle changes of the reflected light, and then transmits them to the control component 60. After receiving the electrical signal, the control component 60 controls the light-emitting area 501 on the light source panel 50 to emit light according to the input information represented by the electrical signal, and provides immediate visual feedback to allow the user to confirm that the operation has been recognized and executed, and that the household appliance 200 performs the corresponding function.

[0083] The shape of the icon aperture 105 should be easily recognizable, allowing users to quickly understand the function represented by the icon aperture 105. The functions corresponding to the icon aperture 105 may include, but are not limited to, power on / off, navigation, security settings, return / undo, pause / resume, lock, and other functions. The specific functions and icon designs of the icon aperture 105 may be specifically defined based on different household appliances 200 and user interfaces, and are not specifically limited in this invention.

[0084] In some embodiments, the light source plate 50 includes icon light sources corresponding to the icon holes 105 in the thickness direction of the display assembly.

[0085] In this way, when the icon light source is illuminated, the emitted light is emitted through the icon hole 105, which can provide the user with immediate visual feedback to confirm that their operation has been recognized and executed.

[0086] Specifically, please combine Figure 1 and Figure 2 The thickness direction of the display assembly is the front-to-back direction. In one embodiment, the light source plate 50 includes an icon light source, which is located behind the icon hole 105 and corresponding to the icon hole 105. When a user touches the icon hole 105, the infrared touch layer 30 converts the user's touch information into an electrical signal and transmits it to the control component 60. The control component 60 controls the icon light source at the corresponding position to emit light based on the touch information, so that the light emitted by the icon light source is emitted through the corresponding icon hole 105, thereby forming a visible icon or indicator on the metal panel 10, providing the user with instant visual feedback, allowing the user to confirm that the operation has been recognized and executed, and to a certain extent enhancing the user experience.

[0087] In some embodiments, the display component includes a sealing layer 20, which includes a connecting layer 203 and a filling portion 201. The filling portion 201 is arranged on one side of the connecting layer 203, and the filling portion 201 fills the light-transmitting hole 103 and the icon hole 105. The connecting layer 203 connects the metal panel 10 and the infrared touch layer 30.

[0088] In this way, the sealing layer 20 is used to seal the light transmission hole 103 and the icon hole 105, ensuring the flatness of the display interaction area 101 when pressed to a certain extent and keeping the light transmission hole 103 and the icon hole 105 clean and hygienic to a certain extent.

[0089] Specifically, please combine Figure 2 The display assembly includes a sealing layer 20, which is coated on the rear surface of the metal panel 10. During the coating process, a portion of the sealing layer 20 material penetrates into the light-transmitting holes 103 and the icon holes 105 of the metal panel 10 to form a filling portion 201.

[0090] The function of the filling portion 201 is to fill the light-transmitting hole 103 and the icon hole 105 on the metal panel 10, and to maintain the sealing and structural integrity of the light-transmitting hole 103 and the icon hole 105 to a certain extent, so that when the user performs touch operations, the surface of the display screen 100 can be kept flat and consistent, thereby improving the user's touch experience and the interactive experience of the process to a certain extent. The portion of the rear surface of the metal panel 10 coated with the sealing layer 20 forms a connecting layer 203, and the connecting layer 203 is located between the metal panel 10 and the infrared touch layer 30, serving as a connecting medium between the metal panel 10 and the infrared touch layer 30.
