The present and future of LED transparent screens

 

 

With the continuous progress of LED technology,LED displays are also in the form of more diversified applications, such as xR virtual shooting, naked-eye 3D, all-in-one machine, cinema screen, rental screen, transparent screen, special-shaped screen, etc., the rise of these innovative applications, accelerate the LED display into the public life, for the LED display industry to create a potential market segment.

Among them, LED transparent screen products are a special existence in many emerging LED displays, with its high transparency and ultra-thin characteristics, which expands the application of LED display products to more different scenes, connecting the virtual and real worlds.

 

i.What is LED transparent screen

 

LED transparent screen, as the name suggests, the biggest feature of the product is its transparent display form, compared with traditional LED display products, the common LED transparent screen on the market today has the characteristics of high transparency, ultra-light and thin, its implementation principle is the innovation of the light bar screen, through the patch manufacturing process, lamp bead packaging, control system for targeted improvement, and plus the hollow structure design to reduce the obstruction of the structural components to the line of sight, thereby greatly improving the perspective effect of the LED display.

 

According to TrendForce's 2024 Global LED Display Market Outlook and Price Cost Analysis, in terms of specifications, the horizontal and vertical spacing of LED transparent displays are different from those of general displays

 

Classified by use scenarios, LED transparent screens can be divided into indoor transparent screens with brightness in the range of 4,000-5,000cd/m2 and transparency of 75%, and outdoor transparent displays with higher brightness. According to the type of LED device, it can be divided into LED transparent screens that use front light and side light, among which front light LED transparent screens are becoming the mainstream type in the market.

 

At present, LED transparent displays are mainly used in department store retail, stage decoration, media advertising, creative cultural tourism and other scenarios, and the main market is China, followed by Europe, America and Asia.It can be favored by the above application scenarios, because the LED transparent screen also has the following characteristics: first, compared with the traditional LED display box, its structure is more flexible, and the specific size of the glass can be customized to better fit the glass curtain wall;

 

Second, the LED transparent screen has good performance such as high transparency, no noise, and low power consumption; Third, the maintenance of LED transparent screen is convenient and safe, saving manpower and material resources; Fourth, its display effect is more attractive than traditional products, which has played a positive role in attracting people and information dissemination.

 

Although the advantages of LED transparent screen are rich, the other side of LED transparent display is the contradiction between screen brightness, clarity and transparency, and the difficulty of further improving the efficiency of transparent screen.

 

In the face of the problems of LED transparent screen, the industry has developed different solutions to solve, and now LED transparent screen can also be subdivided into crystal film screen, film screen, photoelectric glass and other categories, compared with conventional transparent screen, greatly optimize the weight and transparency of the product, and ensure the display clarity to the greatest extent.

 

iI.LED crystal film screen

 

Through the application of laser etching circuits, the line width can be better controlled, the impedance is the same, so that the brightness of each LED chip is the same, and the light transmittance of the crystal film screen can be as high as 95%.

 

III.LED film screen

 

The LED film screen uses a specific bare chip to fix the components on the high-transmittance PCB plate, and through the unique coverslip process, the display module is integrated into a high-transmittance lens substrate, and the product thickness is only 1~3mm. The perspective rate of the LED film screen can reach 70%~95%, which does not affect the indoor and outdoor lighting; The film screen does not need to install a bracket, can be displayed on a curved surface, and the display effect has no dead corners and no color cast; The energy-saving effect is more than 30% of that of ordinary LED displays.

 

IV.LED photoelectric glass

 

LED photoelectric glass is a comprehensive technical product that integrates LED chips, driver chips, embedded control systems, glass deep processing, and chemical processes. The LED chip is built between two pieces of glass, and the technology of glass coating conductivity is used to achieve the photoelectric display effect. The product has the characteristics of longer life, better display effect, high temperature resistance, waterproof and so on. At present, photoelectric glass can be divided into monochrome static, monochrome dynamic, full-color dynamic and other display types.

Emerging LED transparent screen products such as crystal film screen, film screen, and photoelectric glass are now mainly oriented to the mid-to-high-end commercial display field, therefore, the price of the product is higher than that of the conventional transparent screen, but the transparent screen, light and thinness, display effect, and protection performance have also been improved.

In the face of large-scale indoor and outdoor space applications such as retail department stores and museums, LED transparent displays have gradually derived a variety of different types of subdivided products, showing the same wonderful display effect on buildings made of different materials. In the future, with the addition of Micro LED technology, the application of LED transparent displays will be further expanded.
