At present, only a few manufacturers can achieve mass production of this type of products, the transparency can reach 90%, and the high brightness can exceed 4500nits. The IMD package design is used, there are no redundant chip components, the lamp beads are customized in small size, and the surface of the screen body is Cleaner, lamp adhesion can be improved by 30%.

4. Film screen, film screen is also called crystal film screen because it is transparent like crystal. It is a lamp bead with integrated lamp driver, which is mounted on the transparent conductive film. The existing transparent conductive materials on the market include ITO, MetalMesh, nano-silver wires, graphene, etc. The transparent substrates cannot be mass-produced in China due to PEN and CPI, and most of them use PET that cannot withstand high temperature. In addition, there are also products that directly replace the base material PI of FPC with PET. It is mainly suitable for indoor occasions such as atrium fences, glass partitions, etc.

3. Is the transparent screen worth the investment?

LED transparent dosplay screen has the characteristics of transparency, lightness and thinness, and is currently a good display product that cooperates with glass window display. Through the cool video display on the LED transparent screen, it greatly attracts the attention of the incoming and outgoing passengers, enhances the attention of the store, enhances the image of the brand, and promotes the sales of the merchants. Therefore, LED transparent screens have received extensive attention and enthusiasm in the market. Whether it is a commercial complex, a shopping mall, a 4S store, or a window, the SLR is a place with glass, and it is a market where transparent LED displays exist. For example, in the building lighting project, the glass screen required in the future may be replaced with LED transparent display screen, and the number of such projects is still increasing, and the market scale is gradually expanding.

3.1 Market demand

With the continuous development and progress of LED display technology, people's requirements for outdoor advertising media are getting higher and higher, and traditional advertising light boxes, posters and other media have been unable to meet people's new advertising development and needs, so outdoor high-definition LED display The screen stands out and quickly becomes a new trend in the development of new media. In such a large environment, transparent LED display screens have begun to gradually occupy the market demand, especially in the application field of glass curtain walls, occupying an increasingly important position.

At the same time, in urban planning and construction, glass window engineering buildings are more popular, which prompts the emergence of indoor transparent LED displays. Cooperating with the transparent LED screen to display the excellent glass window engineering building, the engineering building has fashion, color diversity, modernity and sense of technology, giving people a unique expressive force.

3.2 Product Advantages

At present, whether it is LED display products in traditional fields or products in emerging segments, LED displays are developing in the direction of lightness and thinness. From outdoor fixed installation to indoor large-screen display, the trend of "transparency" is becoming more and more obvious. At the same time, in the superimposed use of precise advertising push, human-screen interaction, 3D and other technologies, the application scope of transparent LED display is still further expanding.

The newly upgraded installation method of LED transparent screen-indoor installation and outdoor video viewing has stepped into the public's sight. Extremely new applied methods, the status and development trend of video technology and its design concept close to the needs of the mass market have prompted it to develop rapidly in a short period of time, and a new investment hotspot has begun to take shape.

3.3 Market size

Transparent LED displays continue to explode, and the market potential is huge. According to the forecast, by 2025, the market output value of LED transparent screen will be about 10 billion yuan.
