What is a transparent LED display?

The transparent LED display, as the name suggests, stands out for its transparent display form. In comparison to conventional LED display products, the transparent LED screens commonly found on the market today boast high transparency and ultra-lightweight features. This achievement stems from innovations in the strip manufacturing process and SMD production, LED packaging, and control system improvements. Additionally, the incorporation of hollow structural design reduces obstruction to the user’s view, significantly enhancing the see-through effect of the LED display.

According to TrendForce’s "2024 Global LED Video Wall Market Report," transparent LED displays come in varying specifications compared to conventional video walls. They differ in horizontal and vertical pitch and can be categorized into those for indoor use with brightness ranging from 4,000 to 5,000 cd/m2 and 75% transparency, and those for outdoor use with higher brightness levels. They can also be classified by LED chip arrangement, namely front-lit and edge-lit transparent screens, with front-lit models gradually becoming the mainstream.

Currently, transparent displays can be seen in department stores and have been applied to stage decoration, media advertising, creative tourism, and many other settings, with China being the primary market, followed by Europe, America, and Asia.

The popularity of these applications is due to several characteristics of transparent LED screens. Firstly, their structure is more flexible compared to conventional LED display cabinets, allowing for customization to fit specific glass dimensions better. Secondly, transparent displays offer high see-through effects, noiselessness, and low power consumption. Thirdly, they are easy to maintain, safe, and save manpower and resources. Lastly, their display effect is more appealing than ordinary screens, playing a positive role in attracting foot traffic and disseminating information.

Despite the rich advantages of transparent LED displays, they face challenges such as the trade-off between brightness, clarity, and transparency, as well as difficulties in further improving performance.

To address these challenges, manufacturers have developed various solutions. Transparent LED displays now include categories like crystal film screens, adhesive film screens, and electro-optic glass, which greatly optimize product weight and transparency while ensuring maximum display transmittance compared to conventional transparent screens.

Crystal film display: The crystal film LED display is made of flexible transparent films, characterized by lightness, slimness, and design flexibility. By applying laser etching circuits, the line width can be better controlled to ensure uniform impedance, making the brightness of each LED chip consistent. This leads to uniform brightness of the displayed content, while the transmittance of a crystal film screen can reach up to 95%.

Adhesive film display:
With the use of specified dies and unique encapsulation process, the adhesive film LED display fixes its components on high-transparency PCB boards, integrating display modules into high-transmission lens-based substrates. The product thickness is only 1-3mm. The transparency of adhesive displays can reach 70%-95% without affecting indoor and outdoor lighting. Brackets are not needed when installing the display, which can present various contents in curved surfaces without blindside or color deviations. An adhesive film screen is able to save more than 30% of energy use compared to regular models.

Electro-optic glass: The LED electro-optic glass is a comprehensive technical product integrating LED chips, driver ICs, embedded control systems, glass deep processing, and chemical engineering processes. Specifically, LED chips are embedded between two glass sheets, and the technology of glass conductive coating is used to achieve electro-optical display effects. The product has a longer lifespan, better display effects, and features such as high temperature resistance and waterproofing. The glass can be divided into single-color static, single-color dynamic, and full-color dynamic displays.


Crystal film screens, adhesive film displays, electro-optic glass, and other emerging transparent LED screens are now mainly targeted at the mid-to-high-end commercial display market. Therefore, the prices of these products are relatively high compared to regular transparent displays. However, transparency, slimness, display quality, and protective performance have also been improved.

Facing applications in large indoor and outdoor spaces such as retail department stores and museums, various types of transparent LED displays tailored for specific use have emerged. These displays present equally stunning visual effects on buildings made of different materials. In the future, with the introduction of Micro LED technology, applications of transparent LED displays will further expand.

Micro LED Will Become a New Technology for Transparent Displays 

Transparent Micro LED screens are different from regular transparent products. While conventional transparent displays innovate the application of strip screens, Micro LED displays are powered by smaller chips with higher brightness, lower power consumption, longer lifespan, and faster response, along with glass substrates. With the high transparency of glass substrates and the superior display performance of Micro LEDs, transparent Micro LED displays can achieve both high transparency and high definition effects, promising even more exciting prospects for future development.

Today, major display manufacturers such as AUO, Samsung, Tianma, and PlayNitride have entered the transparent Micro LED market, expanding the application of transparent LED products from public transportation and commercial applications to areas such as automotive displays and consumer electronics.

AUO: Reportedly, AUO’s transparent Micro LED screens are applicable to retail, public transportation, automotive displays, consumer electronics, and other fields. Just recently, Lenovo unveiled a concept laptop called the ThinkBook featuring AUO’s 17.3-inch transparent Micro LED display with a resolution of 720P and a brightness of up to 1,000 nits.
