Smartphone makers have been pursuing the true bezel-less design over the past few years. We saw this race reach its peak a couple of years ago with the advent of pop-up cameras. However, it has basically been established, with most devices today delivering good screen proportions. In fact, we only see thick bezels on devices in the low-end segment nowadays. However, some brands like TECNO are not convinced that we’ve hit the limits of screen technology.
The Last Millimeter Has Been the Hardest to Remove
As said above, the modern flagship phones already feature very thin bezels, but some still suffer from a small black border surrounding the display. This border is usually between 1mm and 2mm wide, and it exists for technical reasons rather than design choices.
Display circuits, screen packaging, structural support, and safety clearances all require a small inactive area around the panel. That hidden hardware creates the black edge users still see on virtually every smartphone today.
TECNO says its engineers focused on solving the “last millimeter” problem rather than simply making the bezels thinner. According to the company, the new concept compresses the visible border to 0 microns, allowing the active display to extend to the phone’s outer edge.
More Than Just a New Screen
However, removing this last millimeter wasn’t an easy task. This bezel-free device needed much more than a different display panel. TECNO says it redesigned the phone’s internal architecture from the ground up. Engineers used advanced internal stacking techniques, a new structural layout, and custom display packaging to fit all the necessary components without leaving a visible black edge.
Instead of treating the display as a separate component inside the frame, the company rebuilt how the screen and the phone’s internal hardware work together. This engineering challenge is arguably the most interesting part of the project.
Modern smartphones are packed with display drivers, antennas, sensors, speakers, cameras, and structural reinforcements. Moving or shrinking these components without affecting durability or performance is a significant technical hurdle. Apparently, Tecno managed to overcome these challenges.
A Different Viewing Experience
A borderless display changes more than the appearance of a phone. Without a visible black frame, videos stretch naturally across the entire front of the device, creating a more immersive viewing experience. Games also benefit from the extra screen area, while reading articles, browsing photos, or scrolling through apps can feel more natural because there is no visual interruption around the edges.
TECNO describes the effect as making the display appear to “float” in the user’s hand, with digital content extending seamlessly to the outer frame.
The Technology Goes Beyond the Display
The company says the technologies developed for this concept are not limited to the screen itself. TECNO expects the engineering work behind the project to influence future developments in several areas, including:
- Camera integration
- Touch sensitivity
- Audio design
- Smart UI interactions
- Internal structural engineering
These improvements could eventually appear in future flagship smartphones, even if the complete 0mm design remains exclusive to concept devices for now. In fact, the design barriers that had been broken with this phone could also be adopted by other brands in the future.

TECNO Gives Us A Glimpse Of Future Smartphones
Most concept phones never reach stores exactly as they are shown. Even so, they often introduce new ideas that later appear in real products. It is still too early to know if a true 0mm display will enter mass production. However, the technology behind this concept is an important step forward. It could help remove one of the last visible borders on modern smartphones and shape the design of future devi
