1.What is a holographic screen? (1)
Holographic screen is a display technology that can create three-dimensional images or animations that seem to be suspended in the air. Unlike traditional flat display technology, holographic screen can present a realistic three-dimensional effect, giving people an immersive and tactile illusion.
2.LED holographic screen technology principle
LED light array:LED holographic screens are made up of hundreds or thousands of small LED lights. These LED lights are arranged in an array, usually on a plane. Each LED light can be independently controlled for brightness and color.
Spatial light modulation: The basic principle of LED holographic screen is to generate interference and diffraction effects of light waves through spatial light modulation. Each LED light emits light at different time points, generating a series of light waves.
Generate wavefront: By controlling the brightness and color of the LED light, a specific wavefront can be generated, which is the shape of the leading edge of the light wave propagating in space. The wavefront can be flat, spherical, or other shapes.
Holographic encoding: In order to display a specific holographic image or animation, the desired image needs to be converted into the corresponding holographic encoding. This usually involves decomposing the image into components of interference and diffraction of multiple light waves.
Optical reflection and refraction: Behind the LED holographic screen, a lens or reflector is usually placed. These optical components can reflect and refract the light waves emitted by the LED to form a visible three-dimensional image in the air.
Stereoscopic image viewing:Through the perspective of the observer, you can see the stereoscopic image formed in the air. Due to the interference and diffraction effects of light waves, the observer can see the image from different angles, creating a three-dimensional illusion.
There are many holographic screen technologies, including transmissive holographic screens, reflective holographic screens, and TV-type holographic screens. Transmissive holographic screens form images by transmitting light beams through objects, reflective holographic screens present images by reflecting light beams on the surface of objects, and TV-type holographic screens apply holographic technology to the field of TV display to achieve visual holographic video playback.
3.What are the holographic products?

4.Characteristics of LED holographic display(2)
One.Ultra-thin design
The thickness of the LED holographic transparent screen is less than 2MM, it is light and transparent, and will not block the background, making the visual effect more transparent. Weighing only 3KG per square meter, it is bendable, cuttable, and flexible to use, just like a large “film”. It uses a special adhesive with an adhesive force equivalent to 6 kg/square meter, and is firmly adsorbed on transparent glass.
Two.high definition and bright
The sensory permeability of the entire series of products can reach over 80%, and the number of pixels in the same area is 4 to 5 times that on the market. There is no stripe segmentation effect, and the pixels are invisible to the naked eye from 3 meters away, making it truly HD highlights.
Three.Autonomous driver IC
The use of self-developed IC with extremely strong driving force, coupled with high-quality materials and full-standard processes, ensures the high performance and stability of the holographic transparent screen. With high standards of craftsmanship and clever design, the entire screen is truly transparent. Among them, the pixels with equal spacing P3.91 can achieve 80% sensory transparency, and the pixels with equal spacing P6.25 can achieve 90% sensory transparency. They are mounted on transparent glass and appear as a “screen” when displayed. When the lights are off, it is a “transparent film screen”.
Four.Immersive experience
The design of the LED holographic transparent screen enables the three-dimensional fusion of the scenes before and after the screen and the images on the screen, forming a strong three-dimensional sense of suspension and bringing an immersive experience to users.
Five.Energy saving and environmental protection
The LED holographic transparent screen uses energy-saving and environmentally friendly materials. The design pursues ultra-light, ultra-thin and high transparency, which significantly reduces energy consumption. Different from traditional LED displays, transparent LED screens have a softer display effect and reduce the impact of light pollution on the environment. . The materials used are not only environmentally friendly, but can also be recycled and reused to reduce the environmental burden at the source. The holographic screen optimizes energy use through the intelligent control system, further improving the energy-saving effect.

Four.Low content compatibility
The holographic LED display can achieve the best visual effect only when it plays professionally designed holographic 3D image content; however, its compatibility with ordinary 2D image content is extremely poor, so its use is highly limited.
7.Cost and feasibility of LED holographic screens
The cost and feasibility of LED holographic screens vary depending on multiple factors, including screen size, resolution, technical complexity, and market demand. The following are general considerations for the cost and feasibility of LED holographic screens:
Manufacturing cost: The manufacturing cost of LED holographic screens is usually high. This is because the LED light array requires a large number of LED components, as well as complex optical components and control systems. In addition, the manufacturing process may also involve high-precision calibration and adjustment, which increases the cost.
Material Cost:The materials used in LED holographic screens may also have an impact on the cost. High-quality LED lights, optical components, and auxiliary equipment may increase manufacturing costs. In addition, special material requirements and supply chain costs may also increase the overall cost.
Resolution and size: The higher the resolution and size of the LED holographic screen, the higher the cost. High resolution requires more LED lights and a more complex control system. Large screens require more components and a larger manufacturing process.
Viewing angle and viewing experience: The viewing angle of the LED holographic screen is crucial to the viewing experience. A larger viewing angle usually requires more complex optical design and additional technical support, which may increase costs.
Application fields and market demand: The feasibility of LED holographic screens is also related to specific application fields and market demand. Some industries and venues may be more willing to invest in novel display technologies, while other fields may be cost-sensitive or have low demand.
Although the cost of LED holographic screens may be high at present, it is expected to gradually decrease as the technology advances and the market matures. This will make LED holographic screens more feasible and adopted in a wider range of applications. In addition, as market demand grows, more competition and innovation may emerge, driving cost reduction and technological improvements.
