E Ink will bring its BMW-backed color-changing e-paper vehicle technology to Computex 2026, showcasing the hood structure of the BMW iX3 Flow Edition in the event’s electronic paper industry zone. The display follows BMW’s unveiling of the iX3 Flow Edition at Auto China 2026 in Beijing, where the model adopted E Ink Prism technology and moved toward mass production after more than five years of E Ink development work on vehicle surface applications.
E-paper moves beyond displays
E Ink said its color-changing electronic paper concept car will make its debut at Computex 2026, using the company’s latest variable-color e-paper materials to show how the technology can move beyond display interfaces into 3D curved surfaces, irregular surfaces, and smart surfaces.
The company said the BMW iX3 Flow Edition represents a more commercially mature application, while the color-changing e-paper concept car points to the technology’s longer-term roadmap.
E Ink chairman Johnson Lee said electronic paper is well-suited to surface applications, with Prism technology illustrating the company’s broader goal. E Ink is not positioning e-paper against LCD or OLED, Lee said, but is seeking to develop the surfaces market, from BMW vehicle bodies to electronic shelf labels (ESLs), where paper on retail shelves is replaced by electronic paper.
Large-scale vehicle adoption would require far larger e-paper surface areas, making production line expansion essential. A greater scale could lower costs and support wider use of electronic paper across more surface applications.
BMW drives outdoor e-paper applications
Lee said BMW is strategically important to E Ink because outdoor e-paper applications previously required protective covers. Vehicle surfaces, by contrast, must resist scratches, water, and harsh environments, allowing the BMW collaboration to give E Ink substantial technical know-how for outdoor applications.
Asked why E Ink spent so much time working with BMW, Lee said: “Because it pushed us into another stage. From the perspective of the company’s vision, this is a leap in technical threshold.”
E Ink sees outdoor applications, including outdoor advertising and roadside uses, as the largest future opportunity for electronic paper. These markets require much greater e-paper surface area, giving the company a path to larger-scale demand.
Lee stressed that the BMW collaboration has helped E Ink build genuine outdoor e-paper technology and prepare for its next stage of deployment, with more surface-based products planned.
E Ink and cholesteric LCD target different markets
Lee also rejected a direct comparison with cholesteric liquid crystal electronic paper, saying the two technologies target different product levels and markets. “E Ink focuses on surface applications, and the markets emphasized by the two technologies are different,” he said.
E Ink said the BMW iX3 Flow Edition uses E Ink Prism black-and-white flexible electronic paper materials. The design has passed BMW’s quality tests and meets the requirements of automotive engineering and real-world use, showing that E Ink Prism can support multiple environments and application scenarios. With eight animation effects, drivers can customize the vehicle’s exterior by mood, personality, or driving situation, adding a new layer of expression and personalization.
The BMW iX3 Flow Edition is also the world’s first vehicle model to adopt E Ink Prism technology and move toward mass production, marking a key step for vehicle surface innovation.
3D curved surfaces expand e-paper design
The color-changing electronic paper concept car, making its global debut, uses E Ink Prism color-formable electronic paper materials that can wrap around 3D curved surfaces. The vehicle is the latest technology demonstration from E Ink’s R&D team.
E Ink said the concept car applies electronic paper materials to 3D curved surfaces, including the vehicle body and wheel rims, through stretching or thermoforming processes. A program system can control the materials to produce multiple color changes, highlighting the potential of e-paper technology in multi-material surface integration and smart exterior applications.
Beyond vehicle surfaces, E Ink is extending the technology to other curved objects, giving product exterior design more color variation and personalization options.
From screens to smart surfaces
The concept car uses a BMW production vehicle as its display platform, showing how E Ink Prism can be applied to existing products and shapes to create a new appearance and user experience. Although the color-changing electronic paper materials remain in development and testing, E Ink said the demonstration will help assess applications across different curved surfaces, shapes, and carriers, serving as a reference for future material development and application design
E Ink said electronic paper is expanding from traditional displays into lifestyle and craft scenarios, with e-paper materials evolving from screens into smart surface solutions that can be integrated into a wide range of products.
At COMPUTEX 2026, E Ink will work with upstream and downstream electronic paper ecosystem partners to create an electronic paper industry zone covering color e-paper applications in large-format signage, color-changing vehicle bodies, retail media, consumer products, and lifestyle aesthetics. The showcase will present the industry’s shift toward low-carbon displays and smart surfaces.
