[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the various embodiments and features described below can be combined with each other.

[0027] Please refer to Figures 1 to 4 As shown, some embodiments of this utility model provide a mirror display screen, including: a housing 101, in which a circuit board for carrying a driving circuit is disposed, and a mirror screen assembly 201 is embedded in the housing; the mirror screen assembly 201 is sequentially attached from the outside to the inside with a first polarizing plate 201, a liquid crystal panel 203, a composite layer, a second polarizing plate 202, and a backlight 206; the liquid crystal panel 203 and the backlight 206 are electrically connected to the circuit board; the composite layer includes a reflective material layer 204 and a transparent layer 205 located on the same plane and of the same thickness.

[0028] Through a unique mirror screen assembly 201 structural design, a composite layer consisting of a reflective material layer 204 and a transparent layer is placed between the liquid crystal panel 203 and the second polarizing plate 202. This allows the reflective material layer 204 to function as a mirror for reflection and decoration when the display is not displaying an image; when displaying an image, light passes through the transparent layer for normal display, thus enabling the display to simultaneously possess both decorative and display functions, solving the problem of traditional displays having only one function. Simultaneously, the housing 101 carries the driving circuitry, providing a stable installation environment for all components and ensuring the normal operation of the display. Figure 1As shown, the aforementioned mirror screen assembly 201 is located in the center of the entire device. When the backlight is off, the entire display screen acts as a mirror. When powered on, the liquid crystal panel 203 is activated, and the light emitted by the backlight 206 travels from the second polarizer 202, through the transparent layer 205, to the liquid crystal panel 203, and then through the first polarizer 201 before exiting. Simultaneously, the light emitted by the backlight 203 travels from the second polarizer 202, through the reflective material layer 204, to the liquid crystal panel 203, and then through the first polarizer 201 before exiting. The light is emitted from the first polarizing plate 201, passes through the liquid crystal panel 203, and is reflected by the reflective material layer 204. It then passes back through the liquid crystal panel 203 and then through the first polarizing plate 201 again. This process not only forms an image display but also compensates for the poor image brightness caused by the lower light transmittance of the reflective material layer 204 compared to the transparent layer. Since the display principle of a liquid crystal screen requires a backlight to provide a certain brightness, the liquid crystal panel 203 can display an image of a certain brightness. When the backlight is activated, it is equivalent to a full-screen display. Furthermore, the display function can be partially used. For example, when the liquid crystal panel 203 is activated, the backlight 206 can be deactivated. Because the backlight 206 is not lit, the liquid crystal at the transparent layer 204 cannot display an image of a certain brightness, while the reflective material layer 204 can receive light through reflection of ambient light, allowing the corresponding liquid crystal panel 203 to display an image. The display size of the screen can be adjusted by the driving circuit based on whether the backlight is lit. For example, when this mirrored display screen is installed in a family living room, it functions like an ordinary mirror when the display function is off, and can be used to check one's appearance or decorate the wall; when the display function is on, it can play TV programs, family photos, and other content.

[0029] It should be noted that when the liquid crystal layer inside the LCD screen is driven, it can display corresponding images. Due to the lack of light, the images displayed on it cannot be seen clearly because there is no light. By adding a backlight 26 behind the LCD panel, the LCD panel can display images with a certain brightness.

[0030] In some embodiments of this utility model, the transparent layer 205 is located on the outer periphery of the reflective material layer 204. The transparent layer 205, located on the outer periphery of the reflective material layer 204, optimizes the mirror display effect and light transmission performance. When not in use, the reflective material layer 204 reflects light more uniformly, enhancing the mirror effect; when in use, the surrounding transparent layer 205 ensures clear image display, reduces interference from the reflective material on the displayed content, and further improves the synergy between the display screen's decoration and display function.

[0031] Furthermore, a touch panel (not shown in the figure) is also attached to the outside of the first polarizing plate 201, and the touch panel is electrically connected to the circuit board. The touch panel, attached to the outside of the first polarizing plate 201 and electrically connected to the circuit board, adds touch interaction functionality to the mirror display screen. Users can perform functions such as switching display content and adjusting display parameters through touch operation, expanding the application scenarios of the display screen, improving the human-computer interaction experience, and making the product more practical and convenient in addition to its decorative and display functions. For example, if this mirror display screen is installed in a hotel lobby, guests can use touch operation to inquire about hotel services, view information about nearby attractions, and switch between different artistic images for decoration according to their preferences.

[0032] In some embodiments of this utility model, a glass layer 102 is further bonded to the front end of the first polarizing plate 201 or the front end of the touch panel. Bonding a glass layer to the front end of the first polarizing plate 201 or the touch panel enhances the physical protection performance of the mirror display screen, improves its wear resistance and impact resistance, extends its service life, and also improves the flatness and aesthetics of the display screen surface, better meeting decorative functional requirements. For example, mirror displays installed in public places such as airports and train stations are prone to collisions and friction due to high pedestrian traffic. The glass layer effectively protects the internal components, maintains the clarity of the mirror and the normal display, while the smooth glass surface also enhances the overall decorative effect.

[0033] Furthermore, the reflective material layer 204 is a one-way reflective film. The aforementioned reflective material layer 204 uses a one-way reflective film, which possesses unique optical properties, achieving a mirror-like reflection effect while maintaining a certain level of light transmittance. When the display screen shows content, the one-way reflective film ensures a clear image; when not displaying content, it provides a good mirror effect, further optimizing the balance between the display screen's decoration and display function. Moreover, the one-way reflective film has a relatively low cost, which is beneficial for the product's widespread application. For example, installing a mirror display screen using a one-way reflective film in the rearview mirror of a car allows it to function as a normal rearview mirror when not displaying navigation or other information; when displaying navigation routes, vehicle information, or other content, the information is clearly visible without affecting driving safety, while also enhancing the technological feel and decorative effect of the vehicle interior.

[0034] It's important to note that one-way transparent reflective film (also known as reflective one-way vision film) is a material that combines one-way visibility and reflective properties. Examples of one-way transparent reflective film include glass in some buildings, sunglasses, and car window tinting. The front is a mirror used to reflect sunlight, providing a light source for reading in sunlight. The back of the mirror, however, allows light to pass through, providing a channel for the screen's backlight. Semi-reflective LCD screens reflect light and also have a backlight. In good lighting conditions, the backlight can be turned off, utilizing reflected light; in poor lighting conditions, the backlight can be turned on. Primarily used in small to medium-sized products, they are lightweight, energy-efficient, and adaptable to various lighting environments.

[0035] In some embodiments of this utility model, the circuit board is also electrically connected to a camera 108. The camera 108 faces the front end of the first polarizing plate 201. The circuit board's electrical connection to the camera 108 and its orientation towards the front end of the first polarizing plate 201 enables the mirror display screen to have image acquisition capabilities, which can be used for video calls, facial recognition, photography, etc., further enriching the product's functionality. For example, in a video call scenario, the mirror display screen can serve as both a screen for displaying images and a means of capturing images through the camera, enabling two-way interaction and expanding the product's application in the field of intelligent interaction. In an office setting, using this mirror display screen for video conferencing allows participants to communicate via video, while the mirror function can also be used to groom oneself and enhance one's appearance during meetings. In addition, the aforementioned camera can also be used to detect whether a face is close, which can further enhance its application scenarios. For example, this mirror display screen can be installed in clothing counters in shopping malls. When the camera detects that a person trying on clothes is approaching, it switches to mirror mode. When the person trying on clothes does not need to use the display function, they can obtain a large area of ​​clear mirror reflection, making it easy to view the overall effect of the clothing. When the person trying on clothes moves away, the display function can be activated to display new product recommendations, styling tutorials, and other content without affecting the visual experience.

[0036] Furthermore, the housing 101 is also equipped with a camera switch 105, a LAN interface 105, a USB interface 107, a power interface 103, and a power switch 104, all electrically connected to the circuit board. The housing 101 features various interfaces and switches, such as the camera switch 105, LAN interface 105, USB interface 107, power interface 103, and power switch 104. This not only facilitates the connection and power management of the mirror display to external devices, but also enables network connectivity via the LAN interface 105 for remote data transmission and control. The USB interface 107 allows for easy access to storage devices to read or store data. The camera switch 105 allows for flexible control of the camera 108's on / off state, ensuring user privacy. The power interface 103 and the power switch ensure normal power supply and operation of the display, making the product more functional and versatile. For example, this mirror display can be installed in a school classroom. Teachers can connect a USB flash drive via the USB interface to display teaching materials, connect to the campus network via the LAN interface to access teaching resources, and use the camera switch to control the camera for recording or video teaching, conveniently and quickly meeting the needs of various teaching scenarios.

[0037] Some embodiments of this utility model, such as Figure 4 As shown, the back of the housing 101 is provided with mounting holes 110 and speaker holes 109; a speaker electrically connected to the circuit board is correspondingly arranged at the position of the speaker hole 109. The mounting holes 110 and speaker holes 109 on the back of the housing 101, with a speaker positioned at the corresponding position of the speaker hole 109, facilitate the fixed installation of the display screen, suitable for various installation environments. The speaker enables the display screen to have audio playback functionality, allowing sound to be played simultaneously with the display, such as audio during video playback or voice prompts, enhancing the user's audiovisual experience and further enriching the product's functionality. This gives the mirror display screen more comprehensive multimedia capabilities beyond its decorative and display functions. For example, installing this mirror display screen in a gym, fixing it to the wall through the mounting holes 110, allows the display screen to play fitness tutorial videos while the speaker plays the coach's guidance and background music, creating a better fitness atmosphere and improving the user experience.
