Question

How does a transparent screen (not an LED) work?

Answer 1

First, let me introduce what they are. One is a transparent screen. Transparent screen interactive displays are a new type of display method based on transparent display screens, combined with touch and software video. This is also true in the LED display industry. Transparent display screens can achieve a screen as transparent as glass, maintaining transparency while ensuring the richness of color and display details of dynamic images. Therefore, transparent screen interactive display devices allow users to view exhibits behind the screen up close and interact with the dynamic information on the transparent display screen. LED grid screens are now widely used in the industry as grid-shaped LED displays, and are also used as another name.

Their form is perforated or web-like; industry professionals also call them grids, perforated images, etc. So which one is better? Today, I'll introduce the advantages of LED transparent screens:

High transparency: The transparency at the highest pixel count can reach 75%-95%, making the screen almost invisible from a 10-meter line of sight.

Easy installation: Modules can be quickly and easily fixed to the bracket by hand, and customized installations are also available. Lightweight and Thin: Including all structure and power supply, it weighs only 12kg per square meter, half the weight of traditional screens. This ultra-light weight makes transportation very convenient and cost-effective.

High Brightness and Low Energy Consumption: Utilizing custom-designed high-brightness, high-efficiency LED chips, the maximum power consumption is only 800W at a screen brightness of 5000cd/m².

LED energy consumption is not only lower than projectors and LCD displays, but the high brightness of the screen also ensures clear visibility even in bright sunlight. Easy Maintenance: Long lifespan; only the LED strips need to be replaced, not the entire module. Uses outdoor standard packaged LEDs, UV resistant.

Advantages of Transparent LED Grid Screen: Lightweight and Low Wind Load: The lightweight design is due to the grid pattern of the screen, allowing the LED display to be permeable to air, thus providing excellent wind load resistance. High Efficiency and Low Power Consumption: True energy saving comes from high-brightness, high-efficiency LEDs and a high-conversion-efficiency power supply.

Highly integrated (built-in power supply and receiver card, each unit can work independently; power and signal are connected by a single cable); IP67 high protection rating. IP67 refers to immersion waterproofing, meaning the entire product can be submerged. Compared to IP65's surface protection, this represents a significant difference.

Easy to install and maintain. No steel structure installation required, no air conditioning needed, can be front-mounted or rear-mounted. An LED grid screen is an LED screen composed of light strips forming a grid shape, also called an LED light strip screen. It is mainly used in outdoor walls, glass curtain walls, building rooftops, etc.

LED grid screens break through the limitations of conventional LED displays on building structures and walls, making projects more flexible and offering more choices. LED grid screens have a lifespan of 2-3 years. They are a type of lighting LED display product, generally used indoors because of their 30-60% transmittance and relatively low overall power consumption. They use natural ventilation for heat dissipation, but the temperature rises relatively, requiring strict installation environment conditions. The advantage is the integrated design of the control box and mounting structure, resulting in a smaller installation space.

LED transparent screens have a significantly longer lifespan than LED grid screens, reaching up to 50,000 hours. They are commonly used in architectural media and interactive media applications. They have very low power consumption and excellent energy-saving performance. This transparent LED glass is extremely thin, only the thickness of ordinary glass, making it easy to install. It has a transparency of 99% and a light transmittance of ≥80%. Moreover, it requires no heat dissipation, is highly weather-resistant, and has the advantages of being waterproof and impact-resistant.

Answer 2

Having discussed so much about LED transparent screens and displays, I seem to have forgotten to explain why they give off a transparent visual effect. What is the principle behind this transparency? The principle behind the transparency of a transparent screen can be explained from three aspects:

1. Manufacturing Process: LED transparent screens are an innovation based on traditional LED displays. They improve surface mount technology, LED chip packaging, and control systems, and incorporate a perforated design structure. This design significantly reduces the obstruction of the view by structural components, maximizing the transparency effect. Traditional LED displays are solid, opaque screens; LED transparent screens transform the traditional LED screen into individual light strips with a perforated design, achieving a transparent visual effect.

2. Screen Cabinet: The cabinet of an LED transparent screen adopts a simplified, frameless design, reducing the width of the cabinet frame and the number of light strips to maximize transparency. Installed behind glass, close to the glass, the unit size can be customized according to the glass size, minimizing the impact on the light transmittance of the glass curtain wall and facilitating installation and maintenance. Therefore, from a distance, LED screens rarely obstruct the original curtain wall, giving a transparent feel. Traditional LED screens, when off, obstruct the building's curtain wall, appearing completely dark at night, which is visually unappealing.

3. The video source of the LED transparent screen is a crucial factor determining its transparency. A key principle behind its transparency is determined by the content being played. We know that screen images are illuminated by LEDs. If the background of the video content is black, then when played on a transparent screen, the black areas do not emit light. Because the transparent screen itself is perforated, and the black areas of the displayed image are not shown, it creates a more transparent visual effect.

Of course, it's also important to design less important parts of the video content as black, as this helps to highlight the main subject on the transparent screen.
