Tecno develops concept phone with no black bezel around the screen

Tecno has developed a concept smartphone called Bezelless that has no black bezel around the screen. The device, which will be displayed at the IFA trade show in Berlin, will not go on sale. The prototype demonstrates that the inactive edge of an OLED panel can be hidden, allowing the screen to extend directly to the chassis. However, a thin physical frame still remains around the screen.

The concept features a 6.78-inch OLED display. The panel offers a 1.5K resolution and a 144 Hz refresh rate, making motion on the screen appear smoother. When viewed straight on, the silver frame begins as soon as the display ends, with no black strip visible in between. A very thin black line beneath the frame can be seen only when the smartphone is viewed at an angle.

Tecno achieved this appearance by using 2 layers of protective glass. The upper glass extends to the edge of the frame, while the lower glass and OLED panel extend beneath the frame. Because of this design, the display is installed from the back of the smartphone rather than from the front. At the front, the panel is secured with a special adhesive placed between the frame and the lower glass.

The Bezelless model has a MediaTek Dimensity 7400e processor, 8 GB of RAM, and 256 GB of internal storage. Although the device has a 6,000 mAh battery, its chassis is relatively thin and light. The module on the back gives the impression of having 3 cameras but actually contains 2. These are a 50 MP main camera and an 8 MP ultrawide camera, while a 32 MP selfie camera is located on the front.

Compared with the 2026 Samsung Galaxy S26 Plus, Bezelless has a slightly narrower border around the screen. However, the difference is not significant and adds no new functionality to everyday use. The absence of a black bezel makes photos and videos appear wider, while the Android interface also extends to the edge of the display. The same approach could allow for a larger screen or a slightly smaller chassis.

The rear panel features a red LED notification light and a 3D butterfly pattern whose wings appear to rise from the surface as the light changes. Because the device is only a concept, it remains unclear when this design will be ready for mass production. Nevertheless, the prototype demonstrates that it is technically possible to conceal the black display bezel completely. Apple is reportedly developing a model with a similar display for the 20th anniversary of the iPhone series in 2027.
