Pop-up cameraAlong with the relatively rough design of the Redmi series, the design of the Redmi K20 is extremely delicate, and many design elements that have never appeared in the Redmi products have been tried, especially this screen. Without the occlusion of water droplets and the flaws of punching, the Redmi K20 presents the most complete screen, called the “extreme full screen”. Behind this design is the support of a higher-cost lift structure. The Redmi K20’s front camera module is located on the top left side and houses a 20-megapixel camera that is driven by a stepper motor and can be raised in 0.8 seconds when needed. Interestingly, a transparent strip of light is added to each side of the module, which can be accompanied by a red glow effect, which makes the camera module have more rituals during the lifting process. In terms of reliability, the Redmi K20’s lift camera has a lifespan of up to 300,000 times. The lens surface is covered with a sapphire glass cover, which is more scratch-resistant and wearable. In terms of drop protection, Redmi K20 has a dual protection mechanism. On the one hand, the sensor detects the sensor in time, and the drive module actively retracts. On the other hand, the spring physical protection is built in, which provides buffer margin and better protects the front. Camera and lifting structure.
Extremely comprehensive screenThe Redmi K20 has significantly narrowed down the four frames, especially the lower frame. By introducing the COF flexible packaging process, the frame of the screen module itself is narrowed, and the smart antenna switching technology is further used to further reduce the clearance area. This screen is consistent with Xiaomi 9, which optimizes the display under strong light and low light, including Sunscreen 2.0, smooth transition of highlight mode, low-light gamut compensation and grayscale optimization. At the same time, the eye protection mode has also been retained and passed the VDE low blue eye protection certification of the German Institute of Electrical Engineers. Advancing with the times, Redmi K20 supports hardware-level DC dimming, which is to integrate the millet self-developing algorithm directly into the screen driver chip, ensuring the integrity of the data transmitted to the OLED panel by the underlying system, resulting in grayscale and color bits. There is no loss in the number, avoiding the “DC-like dimming scheme” due to mask grayscale resolution and color resolution degradation caused by mask + dither dimming, bringing more natural visual effects in low light. In addition to the display, this screen is also equipped with a seventh-generation screen fingerprint. This is a coordinated upgrade of hardware and software compared to the previous generation. The first is the hardware level, using the latest optical fingerprinting scheme of Huiding. The single pixel area of ??the lens module has reached 7.2?m, which is 100% higher than that of the sixth-generation screen fingerprint.
Flame patternThe Redmi K20 offers three colors, flame red, glacier blue and carbon black. Among them, flame red and glacier blue adopt the same process. After multi-layer coating treatment, 600 million nano-gratings are carved inside, which echoes the color diffused from inside and outside to form a very rich layer of light and shadow. When the light travels along the surface, the light and shadow on both sides of the fuselage is like a flame, as if it is spiritual.
48 million super wide-angle AI triple cameraPhotographing is a highlight of the Redmi K20, featuring a wide-angle main camera + telephoto sub-photo + super wide-angle sub-photographing triple camera imaging solution. Among them, the wide-angle main camera parameters are not compromised. The Sony IMX586 sensor, which is consistent with many flagships, has a 1/2-inch bottom and 48 million ultra-high-pixel output. The single pixel is 0.8?m, relying on the Quad Bayer array design, under dark light. It can improve the light-sensing ability by “pixel four-in-one”, increase the unit pixel to 1.6?m, output high-definition images of 12 million pixels, and support the high-definition of the 42-megapixel HD through hardware Remosaic pixel rearrangement. Photo, providing higher resolution in a well-lit scene.
?As for the other two sub-photographs, the telephoto sub-photograph is 8-megapixel output, f/2.4 aperture, a 5P lens for zoom and portrait shooting; super wide-angle sub-camera is 13-megapixel output, f/2.4 aperture, 5P lens Supports ultra-wide angle shooting of 124.8 degrees. In addition, the Redmi K20 Pro also introduces a laser focusing system that compensates for traditional phase focusing.
