Tianma Unveils ‘Next-Generation Transparent Micro-LED’ at CIIE… Technology to Watch in the Premium Mobility Market
At the 2025 China International Import Expo (CIIE), Tianma Microelectronics Co. (Tianma) garnered attention from the industry by unveiling its latest Micro LED transparent display technology. CIIE is a national-level import expo led by the Chinese government, where global companies showcase their latest technologies and products to the Chinese market. This year’s event showcased a wide range of digital industry solutions, particularly next-generation display solutions. Tianma’s Micro LED technology received high praise for its diverse applications in automotive, commercial spaces, and smart homes.
Tianma has long been a competitive player in flexible OLED and mobile/automotive displays, and has been actively developing Micro LED technology since 2017. In particular, its glass-based Micro-LED transparent display technology has seen tangible results in recent years, overcoming technical challenges. The company has achieved high mass production by establishing the industry’s first G3.5 generation fully automated mass transfer production line, and its self-developed transfer equipment reportedly achieves a production efficiency of up to 40 million units per hour. This foundation has enhanced the industrial potential of transparent displays and contributed to meeting the key characteristics of transparent displays, including high brightness, high transparency, and low reflectivity.
At this year’s CIIE, Tianma demonstrated technological advancements centered on four key Micro-LED transparent displays. First, the 8.07-inch HUD was introduced, featuring high brightness of 10,000nits, a thin structure, wide color reproducibility, and a fast response speed, making it optimized for vehicle windshield HUD applications.

Automaker Xpeng also participated in the event, discussing how Micro LED technology will transform future vehicle display configurations. An expert from Xpeng stated that displays are evolving beyond simple information displays into interactive spaces, and transparent displays will be key to this transformation. He emphasized that Tianma’s technology holds the potential to deliver new user experiences in advanced vehicles, but noted that cost and energy consumption remain major obstacles to commercialization. He noted that the current technology is likely to be initially applied to luxury vehicles priced at 500,000 yuan (approximately $70,000) or more, and that further cost reductions and process optimization are needed to expand to mass-market vehicles.
Changwook Han, Executive Vice President of UBI Research, commented, “This collaboration demonstrates the expanding role of display technology in the future intelligent mobility market.” He added, “Transparent Micro-LED is a key technology that will transform vehicle interiors into platforms that combine information and interaction, and will be a crucial element in strengthening the differentiation of luxury vehicles in particular.” He also analyzed, “While there are still challenges to address in terms of cost and process efficiency, the technological achievements confirmed at this CIIE demonstrate the potential for new application markets to open up in various fields, including vehicle displays and smart spaces.”
