Xiaomi Announces Mix 4 With Under-Display Camera

Xiaomi is one of the leading smartphone brands in the world, known for its innovative and affordable devices. The company has recently announced the Mix 4, the latest addition to its Mix series that showcases cutting-edge technology and sleek design. The Mix 4 is the first Xiaomi phone to feature an under-display camera, a breakthrough that eliminates the need for a notch or a hole-punch cutout on the screen. In this article, we will explore everything you need to know about the Xiaomi Mix 4, including its features, specs, price, and availability.

What is an under-display camera and how does it work?

An under-display camera is a type of selfie camera that is hidden behind the screen, making it virtually invisible to the eye. Unlike conventional cameras that require a notch or a hole-punch cutout on the screen, an under-display camera allows for a full-screen display without any interruption. This creates a more immersive and seamless viewing experience for the user.

To achieve this, an under-display camera uses a special type of flexible display and circuit design that maximizes the transparency and light transmission in the camera area. The display also uses a new pixel pattern and algorithm that minimize the light refraction and distortion caused by the camera. The camera itself uses a high-resolution sensor and advanced processing techniques to capture clear and detailed selfies.
