Aside from the plethora of products that TECNO has at their MWC 2025 booth like the CAMON 40 Premier, the brand also has several color-changing concept products showcasing different approaches to the back panel.
The first one is what appears to be a colored e-ink embedded into the back panel of a prototype POVA 7. Called “Display Electronic Slurry Technology” or DES for short, what this tech does is it suspends pigments in plasma instead of oil or air, where there’s a cofferdam structure formed around the periphery of each pixel electrode. The idea of this is that it allows the back panel to dynamically change into any graphic on the fly, giving you practically unlimited options for your back panel design.Â
The other color-changing back TECNO has at MWC 2025 is a Photochromic Cellulose Acetate Color back that’s used on a prototype CAMON 30. This one is a more familiar tech as the back panel changes colors when exposed to UV light. We’ve seen this in other phones in the past, and TECNO’s approach involves making the back panels have more vibrant colors when exposed to UV light.
Between the two concepts, we think that the Photochromic Cellulose Acetate Color has a better chance of making it into a production TECNO phone in the future.
