Description

Technical Field

[0001] The present invention relates to the technical field of screens, and particularly to a screen assembly with controllable light display and its application method. Background Art

[0002] In the design of exhibition halls, the creation of an immersive experience often requires appropriate control of the entry of natural light to maintain the mystery and atmosphere of the exhibition hall. However, existing technologies have some limitations in controlling natural light. Firstly, excessive natural light may disrupt the immersion of the exhibition hall, making the layout of the exhibition hall completely visible and lacking the mystery of exploration. To enhance the immersive experience, a common practice is to close the windows to block the introduction of natural light, but this will also cause the exhibition hall to be isolated from the outside world and lack vitality. In addition, when not in use, additional lighting needs to be added to supplement the light source, which not only causes waste of resources but also increases energy consumption.

[0003] Therefore, there is an urgent need in the design of exhibition halls for a device or apparatus that can freely control the entry of natural light to adjust the light in the exhibition area as needed, enhance the visiting experience, and at the same time reduce energy waste to achieve a more environmentally friendly and efficient exhibition environment. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a screen assembly with controllable light display and its application method, which can freely control the entry of natural light to adjust the light in the exhibition area as needed, enhance the visiting experience, and at the same time reduce energy waste.

[0005] The technical solution adopted by the present invention to solve its technical problems is:

[0006] A screen assembly with controllable light display, comprising a frame and a display screen arranged in the middle of the frame, the display screen including a dimming layer, a liquid crystal layer, a mirror layer, and a sensing layer arranged opposite to each other in sequence;

[0007] Wherein, the dimming layer presents two state effects of bright and dark, and the switching between the two state effects is controlled as needed through an electric control signal;

[0008] The liquid crystal layer is a digital content display medium for displaying digital content and is also transmissive;

[0009] The mirror layer is used to protect the display screen and has a full mirror and semi-transparent effect;

[0010] The sensing layer is used for interactive sensing, obtaining instant interactive information of users, and controlling the change of digital content of the liquid crystal layer.

[0011] Preferably, the dimming layer is composed of a light-transmitting glass and a light-transmitting film sheet constructed from a reversible electro-controlled variable-color dimming thin film material. The light-transmitting film sheet realizes the blocking and transmission of light through the induced charge electroosmosis phenomenon and the specific movement or arrangement of charged particles under the action of an electric field. In the absence of voltage, the particles are evenly distributed, thus reflecting and scattering light, and the film sheet presents a "dark" state. When a voltage is applied, the particles move along the direction of the electric field to form an aggregated state, reducing the reflection and scattering of light, presenting transparency, and significantly increasing the light transmittance to present a "bright" state.

[0012] Preferably, the liquid crystal layer is an LED transparent screen with a light transmittance of 70%-85%.

[0013] Preferably, the mirror layer is composed of mirror glass or formed by pasting a mirror film behind tempered glass, forming a mirror on the front and being light-transmitting when lit from the back.

[0016] Preferably, an atomization layer is provided between the dimming layer and the liquid crystal layer. The atomization layer presents two state effects of transparency and semi-transparency, and the switching between the two state effects is controlled as needed through an electric control signal.

[0017] Preferably, the atomization layer is realized by an electronic atomization film to achieve the effects of transparency and semi-transparency. In the natural state, the liquid crystal molecules inside the electronic atomization film are arranged randomly, and the incident light is scattered, and the electronic atomization film is milky white, presenting an opaque state. After being powered on, the dispersed liquid crystal molecules quickly change from random arrangement to directional and regular arrangement, and the incident light can completely pass through, forming a transparent state.

[0018] Preferably, the above-mentioned controllable light display screen assembly is adopted to realize its dark field state or bright field state;

[0019] The method for realizing the dark field state is as follows: Through an electric control signal, the dimming layer is controlled to be in the "dark" state by switching control, so as to block the entry of external light as needed and realize the effect control of the dark field state;

[0020] Play the exhibition digital content through the liquid crystal layer, and obtain the user interaction information through the interaction signal of the sensing layer to realize the real-time interaction of the exhibition digital content;

[0021] The method for realizing the bright field state is as follows: through the electric control signal, the dimming layer is controlled to be turned on or off, and the dimming layer is controlled to be in the "bright" state, and the natural light is allowed to enter, so as to realize the effect control of the bright field state.

[0026] A screen assembly with controllable light display and its application method according to an embodiment of the present invention, compared with the prior art, has the beneficial effects that: by setting the dimming layer, through the electric control signal, the dimming layer is controlled to be turned on or off, and the dimming layer is controlled to be in the "dark" state, so as to block the entry of external light as required and realize the effect control of the dark field state; or through the electric control signal, the dimming layer is controlled to be turned on or off, and the dimming layer is controlled to be in the "bright" state, and the natural light is allowed to enter, so as to realize the effect control of the bright field state, and in cooperation with the liquid crystal layer, the user interaction information is obtained through the interaction signal of the sensing layer to realize the real-time interaction of the digital content for exhibition, realizing the free control of natural light entering, so as to adjust the light in the exhibition area as required, not only improving the visiting experience, but also not requiring additional lighting to supplement the light source, reducing energy consumption.

[0033] The following will further describe in detail the specific embodiments of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0034] Embodiment 1

[0035] As Figures 1-4 shown, a screen assembly of a multi - controllable light display according to a preferred embodiment of the present invention includes a frame 1 and a display screen 2 disposed in the middle of the frame 1. The display screen 2 includes a dimming layer 21, a liquid crystal layer 22, a mirror layer 23, and a sensing layer 24 disposed opposite to each other in sequence;

[0036] Among them, the dimming layer 21 presents two state effects of bright and dark, and the switching between the two state effects is controlled as needed through an electric control signal;

[0037] The liquid crystal layer 22 is a digital content display medium, used to display digital content and can transmit light at the same time;

[0038] The mirror layer 23 is used to protect the display screen and has a full - mirror and semi - transparent effect;

[0039] The sensing layer 24 is used for interactive sensing, obtaining instant user interaction information, and controlling the change of the digital content of the liquid crystal layer.

[0040] Based on the above - mentioned technical features, for the screen assembly of the multi - controllable light display, by setting the dimming layer 21 and controlling the dimming layer 21 through an electric control signal, the dimming layer 21 is controlled to the "dark" state, so as to block the entry of external light as needed and achieve the effect control of the dark - field state; or the dimming layer 21 can be controlled to the "bright" state through an electric control signal, allowing the natural entry of external light to achieve the effect control of the bright - field state. In cooperation with the liquid crystal layer 22, through the interactive signal of the sensing layer, user interaction information is obtained, and real - time exhibition digital content interaction is realized. It realizes the free control of natural light entering and adjusts the light in the exhibition area as needed. It not only improves the visiting experience, but also does not require additional lighting to supplement the light source, reducing energy consumption.

[0041] In this embodiment, the dimming layer 21 is composed of a light-transmitting glass and a light-transmitting film sheet made of a reversible electro-controlled variable-color dimming thin film material. The light-transmitting film sheet realizes the blocking and transmission of light through the induced charge electroosmosis phenomenon and the specific movement or arrangement of charged particles under the action of an electric field. In the absence of voltage, the particles are evenly distributed, thus reflecting and scattering light, and the film sheet presents a "dark" state; when a voltage is applied, the particles move along the direction of the electric field to form an aggregated state, reducing the reflection and scattering of light, presenting transparency, and the light transmittance significantly increases to present a "bright" state. The light transmittance is between 5% and 60%.

[0042] The liquid crystal layer 22 uses an LED transparent screen. The LED transparent screen is transparent and invisible, and the light transmittance is between 70% and 85%, without affecting the daily lighting. In a dark field environment, the LED transparent screen can clearly display the exhibition digital content, and in a bright field environment, the scene outside the exhibition hall can be seen through the LED transparent screen.

[0043] The mirror layer 23 is composed of mirror glass or formed by pasting a mirror film behind tempered glass, presenting a mirror surface when viewed from the front. When it lights up from the back, the scene behind can be seen through the mirror glass. The mirror glass is installed above the liquid crystal layer. In a dark field environment, when the liquid crystal layer behind does not light up, it presents a high-quality mirror effect. When the screen background light of the liquid crystal layer behind is turned on, the screen content behind can be seen through the mirror glass. In a bright field environment, the scene behind can be seen through the mirror glass.

[0044] The sensing layer 24 is composed of an infrared touch frame, forming an interactive recognition area, arranged around above the mirror layer, and real-time identifying and monitoring interactive click events within the area.

[0045] In this embodiment, the frame 1 includes a frame body 11 and a cover plate 12 provided on one side of the frame body 11. A through hole for installing the display screen is formed in the middle of the frame body 11. A notch is provided on the side wall of the through hole, and the notch and the cover plate 12 enclose a card slot 13, and the periphery of the display screen 2 is clamped in the card slot 13. After clamping, the sensing layer 24 is attached to the cover plate 12.

[0046] Meanwhile, for the convenience of connecting the cover plate 12 and the frame body 11, clamping claws 14 are provided on the surface of the cover plate 12, and a clamping groove 15 is provided on the frame body 11, and the clamping claws 14 are clamped in the clamping groove 15.

[0047] Using the above-mentioned controllable light display screen assembly, its application in the dark field state or the bright field state can be realized. Specifically:

[0048] In the dark field state, the screen assembly isolates external light, making the exhibition hall completely dark, creating an immersive space for digital content playback and allowing users to interact with the digital content. The implementation method is as follows: Through an electronic control signal, the dimming layer 21 is controlled to be turned on or off, and the dimming layer 21 is controlled to be in the "dark" state, so as to block the entry of external light as needed and achieve the effect control of the dark field state;

[0049] The exhibition digital content is played through the liquid crystal layer 22, and the user interaction information is obtained through the interaction signal of the sensing layer 24 to achieve real-time interaction of the exhibition digital content;

[0050] In the bright field state, external light can enter through the device part, and the scene outside the exhibition hall can also be seen through the device inside the exhibition hall. At the same time, without adding additional lighting fixtures, the normal operation of the interior can be completed only by natural light. The implementation method is as follows: Through an electronic control signal, the dimming layer 21 is controlled to be turned on or off, and the dimming layer 21 is controlled to be in the "bright" state, allowing natural light to enter, and achieving the effect control of the bright field state. In this state, the liquid crystal layer 22 does not play the exhibition digital content, and the sensing layer 24 does not obtain user interaction information.

[0051] Embodiment 2

[0052] As Figure 5 shown, the difference between this embodiment and Embodiment 1 is that a fogging layer 25 is added. When the added fogging layer 25 is turned on, it can more efficiently block the entry of natural light and better create a dark field effect.

[0053] Specifically, the fogging layer 25 is disposed between the dimming layer 21 and the liquid crystal layer 22, and the fogging layer 25 presents two state effects of transparent and semi-transparent, and the switching between the two state effects is controlled as needed through an electronic control signal.

[0054] The fogging layer 25 is realized by an electronic fogging film to achieve transparent and semi-transparent effects. In the natural state, the liquid crystal molecules inside the electronic fogging film are arranged irregularly, and the incident light is scattered, and the electronic fogging film is milky white and presents an opaque state; after being powered on, the dispersed liquid crystal molecules quickly change from irregular arrangement to directional regular arrangement, and the incident light can completely pass through, forming a transparent state.

[0055] Using this controllable light display screen assembly, its application in the dark field state or the bright field state can also be realized. Specifically:

[0056] In the dark field state, the screen assembly isolates external light, and the exhibition hall is completely dark, creating an immersive space, digital content is played, and users can interact with digital content. The implementation method is: through the electronic control signal, the dimming layer 21 is switched on and off, the dimming layer 21 is controlled to be in the "dark" state, and the atomization layer 25 is controlled to be in the "semi-transparent" state, so as to block the entry of external light as needed, and realize the effect control of the dark field state;

[0057] The digital content is played through the liquid crystal layer 22, and the user interaction information is obtained through the interactive signal of the sensing layer 24, so as to realize the real-time interaction of the digital content;

[0058] In the bright field state, external light can enter through the device part, and the scene outside the exhibition hall can be seen through the device in the exhibition hall. At the same time, the normal operation of the room can be completed by natural light without adding additional lamps. The implementation method is: through the electric control signal, the dimming layer 21 is switched on and off, the dimming layer 21 is controlled to the "bright" state, and the atomization layer 25 is controlled to the "transparent" state, and the natural injection of external light realizes the effect control of the bright field state. In this state, the liquid crystal layer 22 does not play the digital content for display, and the perception layer 24 does not obtain user interaction information.

[0059] In summary, this application has the following advantages:

[0060] Improve the exhibition space experience: This screen assembly can not only serve as a carrier for exhibition hall display, but also can be used for interactive display, enhancing the audience's sense of participation and experience, and improving the interactivity and fun of the exhibition space.

[0061] Reduce waste of energy resources: By precisely controlling light according to exhibition needs and creating different experience scenes, it reduces electricity waste caused by excessive lighting and achieves efficient use of energy.

[0062] Improve the utilization of exhibition space: This screen assembly can adjust the light according to the specific needs of the exhibition area, so that the same space can play multiple functions at different times or in different activities, avoiding the waste of exhibition space and improving the flexibility and efficiency of space.

[0063] Expand exhibition design ideas: The precise control of light by this screen assembly provides more creative space and possible gameplay expansion for exhibition design, providing more creative ideas.

[0064] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
