The 3rd Automotive Intelligent Dimming Glass Industry Forum
April 10, 2025 Shanghai
Automotive smart dimming glass, also known as color-changing glass or smart glass, can adjust the light transmittance according to changes in current or changes in ambient light. This technology has significant advantages in improving driving comfort, safety and energy efficiency.
With the development of new energy vehicles, panoramic sunroof has gradually become a trend. The heat insulation and sun protection of sunroof and personalized needs have promoted the development of panoramic sunroof in a more intelligent direction, and intelligent dimming glass has also become a highlight of new energy vehicles.
At the same time, with the high degree of integration of automobiles, the dimming system of the panoramic canopy of automobiles will be closely linked with the intelligent cockpit, making automobiles smarter and human-vehicle interaction smarter, allowing drivers to feel the convenience brought by the intelligence of automobiles in the era of intelligence.
At present, nearly 20 models are equipped with intelligent dimming glass, such as NIO EC7/EC6/ET5/ES7, Polar Krypton 001/Polar Krypton 009, BYD Song L/Seal, GAC AION S Plus, Avita 12 and so on. With the development of the automotive industry, more equipped models will be launched in the future.
The technical routes of dimming glass mainly include LC (dye liquid crystal), EC (electrochromic), SPD (suspended particles), PDLC (polymer dispersed liquid crystal), etc.
It can be said that the technical route has made a major breakthrough. Different technical routes have their own advantages and disadvantages.
At present, each technical route has development prospects, but in general, the application of these technologies in automotive dimming glass has more or less some development bottlenecks, and there is an urgent need for the industry to overcome some common problems, such as packaging, life, potential difference, materials, etc.
In order to:
- strengthen upstream and downstream cooperation in the industrial chain,
- overcome industry bottlenecks,
- promote industry development
Aibang Smart Car Club will hold the third Automotive Intelligent dimming Glass Industry Forum in Shanghai on April 10, 2025.
At that time, upstream and downstream experts in the industry will be invited to:
- discuss the advantages and pain points of various dimming technologies (EC, PDLC, SPD,) LC);
- delve into the subdivision technologies in the industrial chain of dimming glass, such as film coating technology, vacuum potting technology, flexible transparent electrode film, etc.
- jointly promote the further development of the panoramic canopy dimming industry.
Conference Agenda
The technical routes of dimming glass mainly include LC (dye liquid crystal), EC (electrochromic), SPD (suspended particles), PDLC (polymer dispersed liquid crystal), etc. At present, from the point of view of the equipped models, there are more EC technical routes, and the LC technical route has been substantially equipped with models on the market.
It can be said that the technical route has made a major breakthrough. Different technical routes have their own advantages and disadvantages. At present, each technical route has development prospects, but in general, the application of these technologies in automotive dimming glass more or less exists.
The automotive intelligent dimming glass industry chain includes:
- traditional oems
- new energy oems
- glass assembly manufacturers
- glass manufacturers,
- dimming film manufacturers
- dimming film technology solution providers
- dimming film material suppliers
- dimming film equipment suppliers
- anti-glare rearview mirror manufacturers
- various other raw materials,
- equipment manufacturers
- universities, associations
and so on.
