[0032] This utility model provides a novel composite facial mask digital screen. By combining a light shield with a light-transmitting area and illumination from a first light source, the first film can display unique patterns or information. Furthermore, the combination of a light guide plate and a second light source with the second film further enriches the displayed content, enabling a variety of visual effects within the same display area, including variations in color, brightness, and pattern. This significantly enhances the digital screen's layered display and visual impact. Compared to traditional single-layer mask-laminated display methods, the novel composite facial mask digital screen provided by this utility model offers significant advantages in display quality. This innovative display technology is expected to attract more consumers and meet market demand for personalized and diverse display content, thereby enhancing the product's market competitiveness and increasing market share. By combining multiple mask-laminated display modes and a flexible and controllable light source design, the novel composite facial mask digital screen can provide richer and more detailed display effects tailored to different scenarios and needs. This not only enhances the user's visual experience but also provides a more intuitive and convenient way to access information, thereby improving the overall user experience. Example

[0033] The embodiment of the utility model provides a new composite mask digital screen, such as Figures 1 to 3 As shown, it includes a substrate 10, on which a first light source 110 and a second light source 120 are arranged; a light shield 20, which is arranged on the substrate 10 and includes a light-transmitting area 210; a first film 30, which is arranged on the light shield 20, and the first light source 110 is irradiated onto the first film 30 through the light-transmitting area 210; a light guide plate 40, which is arranged on the first film 30, and the second light source 120 irradiates the light guide plate 40 from the side; and a second film 50, which is arranged on the light guide plate 40.

[0034] In this way, the embodiment of the utility model provides a new composite facial mask digital screen that can overcome the display shortcomings of existing digital tubes and digital screens, enrich the display content, and increase the market competitiveness and market share of the product.

[0035] In this way, by arranging the first light source 110 and the second light source 120 on the substrate 10, and controlling the light through the light-transmitting area 210 of the light shield 20 and the light guide plate 40, respectively, multi-level light processing and display are achieved. This structure enables the digital screen to display more complex and rich visual content, such as different colors, brightness, patterns, etc., in the same location, thereby overcoming the shortcomings of traditional digital tubes or digital screens that display only a single content. The provision of the light shield 20 allows for precise control of the illumination range of the first light source 110, ensuring that light only illuminates the first film 30 through the light-transmitting area 210, achieving precise guidance and utilization of light. At the same time, the function of the light guide plate 40 is to introduce the second light source 120 from the side and evenly distribute it across the entire screen, illuminating the second film 50, further enhancing the diversity and flexibility of the display effect. The superposition of the first film 30 and the second film 50 not only increases the sense of layering of the display, but also allows the display effect to be optimized by selecting different materials, colors and light transmittances. For example, by adjusting the transmittance and reflectivity of the film, light loss can be reduced, image clarity and color saturation can be improved, and displayed content can be made more vivid and realistic. The diverse display and high-quality visual effects of the new composite mask digital screen make it more competitive in the market. This provides a richer and more engaging visual experience, thereby increasing the product's market appeal and market share. Due to the new composite mask digital screen's flexible light control and diverse display effects, it can be applied to a wider range of application scenarios, providing customized solutions for different fields.

[0036] like Figure 1 and Figure 2 As shown, the substrate 10 is a PCB or FPC. More specifically, the substrate 10 includes an epitaxial region 130. The epitaxial region 130 may be provided with a power connection portion, which can be used to control whether the first light source 110 and / or the second light source 120 are powered or lit.

[0037] Among them, the PCB substrate 10 has good stability and reliability, can withstand large currents and voltages, and ensure the normal operation of the digital screen. The processing technology of the PCB substrate 10 is mature, and drilling, wiring, welding and other process processing can be performed as needed to meet the customization needs of the digital screen. Compared with other substrates 10, the cost of the PCB substrate 10 is lower, which is conducive to reducing the production cost of the digital screen. The FPC substrate 10 has excellent flexibility and can be bent and folded, and is suitable for digital screens of various complex shapes and sizes. The FPC substrate 10 is light in weight, which is conducive to reducing the overall weight of the digital screen and improving portability. The FPC substrate 10 can fit tightly on other components of the digital screen, making full use of space and improving the integration and aesthetics of the digital screen.

[0038] Epitaxial region 130 is a specific area on substrate 10 used for mounting and connecting various electronic components and parts. In the new composite mask digital screen, epitaxial region 130 can host the key components of the power connection. The power connection can be configured in various shapes and sizes to accommodate different light sources and circuit layout requirements. It can also be equipped with various protective elements, such as fuses and current-limiting resistors, to ensure circuit safety and stability.

[0039] More specifically, the light shield 20 is made of foam, plastic, EVA or silicone material.

[0040] The foam material has excellent light-blocking properties, effectively blocking unwanted light and ensuring that light only reaches the diaphragm through the light-transmitting area 210. The foam material has a certain degree of elasticity and cushioning properties, protecting other components from external shock and vibration. Foam is easy to cut, paste, and shape, allowing for customized processing. Plastic, on the other hand, has high strength and wear resistance, allowing it to withstand significant external forces and friction, ensuring the long-term stability of the light shield 20. Compared to other materials, plastic is less expensive, which helps reduce the production cost of digital screens. Plastic is easy to injection mold, allowing light shields 20 to be produced in various shapes and sizes to meet different application requirements. EVA is lightweight and flexible, allowing it to be easily attached to the substrate 10 without significantly affecting the overall weight and thickness of the digital screen. By adjusting the EVA material's formulation and thickness, varying light-blocking and light-transmitting properties can be achieved to meet different display requirements. EVA is an environmentally friendly material that does not pollute the environment, meeting the environmental requirements of modern electronic products. Silicone material has high heat resistance and can operate normally in high-temperature environments without deformation or failure due to temperature increases. Silicone material also has excellent aging resistance, maintaining its light-shielding properties and elasticity over time, extending the life of digital screens. Silicone material is also highly stable against most chemicals and will not deteriorate or be damaged by contact with them.

[0041] like Figure 1 and Figure 3 As shown, more specifically, the light-transmitting area 210 is composed of a plurality of openings 2110 , and the positions of the openings 2110 are adapted to the positions of the first light sources 110 .

[0042] It is understandable that the position of the opening 2110 of the light-transmitting area 210 can be precisely designed according to the specific position of the first light source 110. This design ensures that light can be accurately emitted from the light source and irradiated onto the first diaphragm 30 through the opening 2110, avoiding waste and scattering of light. By adjusting the size, shape and distribution of the opening 2110, the distribution and intensity of light can be further optimized. For example, for areas that require highlighting, larger openings 2110 can be designed to allow more light to pass through; for areas that require a soft transition, smaller openings 2110 can be designed or openings 2110 of different shapes can be used to disperse the light. Precise openings 2110 help improve the display quality of the digital screen. By ensuring that light can accurately illuminate the diaphragm, light loss and image blur can be reduced, thereby improving image clarity and color saturation. The precise design of the opening 2110 of the light-transmitting area 210 enables light to be irradiated onto the diaphragm in a predetermined manner, thereby enhancing the visual effect of the digital screen. For example, when displaying dynamic images or text, it can ensure that light is evenly distributed across the entire screen, avoiding problems such as uneven brightness or image deformation. By optimizing the design of the opening 2110 of the light-transmitting area 210, the energy efficiency of the light source can be improved. Since light can accurately illuminate the target area, unnecessary energy loss can be reduced, energy consumption can be reduced, and the service life of the light source can be extended. The precise design of the opening 2110 can also simplify the structural design of the digital screen. Since light can directly illuminate the diaphragm through the opening 2110, additional optical elements or structures can be reduced to guide or disperse the light, thereby reducing production costs and processing difficulty.

[0043] like Figure 1 and Figure 2 As shown, the second light source 120 is protruding from the substrate 10 and passes through the opening 2110. The height of the second light source 120 matches the side surface of the light guide plate 40. More specifically, the second light source 120 includes a plurality of side-emitting lamp beads 1210. It will be appreciated that the height of the side-emitting lamp beads 1210 is higher than the light shield 20 and the first film 30. In this way, the side-emitting lamp beads 1210 can directly illuminate the light guide plate 40 from the side surface of the light guide plate 40.

[0044] As will be appreciated, the second light source 120 is raised above the substrate 10, meaning it is elevated above the plane of the substrate 10. This allows light to pass through the opening 2110 in the light-transmitting region 210 and directly illuminate the light guide plate 40. This allows light to enter the light guide plate 40 more directly and efficiently, reducing reflection and scattering between the substrate 10 and the light guide plate 40. The height of the second light source 120 matches the side of the light guide plate 40, ensuring it fits snugly against the side of the light guide plate 40, resulting in a more uniform light distribution. This design helps reduce light scattering and loss within the light guide plate 40, improving light utilization efficiency. The second light source 120 includes a plurality of side-emitting lamp beads 1210, which emit light directly from the side of the light guide plate 40. These side-emitting lamp beads 1210 ensure a more even distribution of light within the light guide plate 40, thereby improving the display quality and brightness uniformity of the digital screen. The height of the light-emitting lamp beads is higher than the light shield 20 and the first film 30, which means that the light emitted by the lamp beads will not be blocked by the light shield 20 or the first film 30 and can directly illuminate the light guide plate 40. This further improves the utilization efficiency of light and reduces the loss of light during transmission.

[0045] like Figure 1 and Figure 2 As shown, the first light source 110 includes a plurality of LED lamp beads 1110. More specifically, the LED lamp beads 1110 may include one or more of a top-mounted chip, a flip-chip, a surface-mounted lamp, and a side-emitting lamp. It is understood that the light from the LED lamp beads 1110 can be irradiated onto the first diaphragm 30 through the opening 2110.

[0046] Among them, the upright chip LED is a traditional LED structure, in which the chip is directly mounted on the substrate 10 and connected to the external circuit through electrodes. This type of LED has the characteristics of simple structure, low manufacturing cost, and high luminous efficiency, and is suitable for most digital screen applications. The chip of the flip-chip LED is mounted upside down, that is, the electrode of the chip is facing down and in direct contact with the substrate 10. This design helps to reduce the reflection and scattering of light, improve the utilization efficiency of light, and reduce thermal resistance, thereby improving the reliability and life of the LED. The SMD LED is a miniaturized LED with very small size and weight, which is easy to integrate and install. This type of LED has the characteristics of uniform light emission, low power consumption, and long life, and is suitable for digital screen applications that require high integration and low power consumption. The light of the side-emitting LED is emitted from the side of the chip, rather than from the front or bottom. This design allows the light to be more evenly distributed on the light guide plate 40 or the diaphragm, thereby improving the brightness uniformity and display effect of the digital screen.

[0047] In this way, by selecting the appropriate type of LED lamp beads 1110, the light control of the digital screen can be optimized. For example, front-mounted chip LEDs and flip-chip LEDs can be used to achieve different light distribution and brightness adjustment; SMD LEDs can be used to achieve high-integration and low-power display effects; and side-emitting LEDs can be used to improve brightness uniformity and reduce light loss. The luminous efficiency and color saturation of LED lamp beads 1110 directly affect the display effect of the digital screen. Using high-quality LED lamp beads 1110 can ensure that the digital screen has clear, vivid images and colors. Different types of LED lamp beads 1110 also differ in energy efficiency and reliability. For example, flip-chip LEDs have lower thermal resistance and higher reliability; SMD LEDs have lower power consumption and longer life. These characteristics optimize the energy efficiency and reliability of the digital screen.

[0048] More specifically, the first film 30 has patterns and / or texts, and is a fluorescent film or a common black and white film or a color film; the second film 50 has patterns and / or texts, and is a fluorescent film or a common black and white film or a color film.

[0049] In this way, the first diaphragm 30 can be provided with various patterns and texts, which can be achieved by printing, photolithography or other processing methods. The patterns and texts can be customized according to application requirements to achieve specific visual effects or information transmission. Similar to the first diaphragm 30, the second diaphragm 50 can also be designed with various patterns and texts. These patterns and texts can echo or contrast with the patterns and texts on the first diaphragm 30 to achieve a richer visual effect. The diaphragm can be selected as a fluorescent film, an ordinary black and white film or a color film. The fluorescent film can emit fluorescence when excited by light, thereby achieving a more vivid and lively color effect. The ordinary black and white film is suitable for simple text or graphic display. The color film can display a richer color and is suitable for occasions requiring high-quality color display.

[0050] Compared with the prior art, the new composite facial mask digital screen provided by the embodiment of the present invention, by introducing a light shield 20 and a light-transmitting area 210 in combination with the illumination of the first light source 110, enables the first film 30 to present a unique pattern or information. At the same time, the combination of the light guide plate 40 and the second light source 120 with the second film 50 further enriches the display content, enabling a variety of different visual effects to be displayed within the same display area, including changes in color, brightness, pattern, etc., thereby greatly enhancing the display layering and visual impact of the digital screen. Compared with the traditional single-layer mask lamination display method, the new composite facial mask digital screen provided by the present invention has significant advantages in display effects. This innovative display technology can attract more consumers' attention and meet the market demand for personalized and diversified display content, thereby enhancing the product's market competitiveness and increasing market share. Through the display mode composed of multiple layers of masks and the flexible and controllable light source design, the new composite facial mask digital screen can provide richer and more delicate display effects according to different scenarios and needs. This not only enhances the user's visual enjoyment, but also provides users with a more intuitive and convenient way to obtain information, thereby improving the overall user experience.

[0051] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
