In terms of appearance, the biggest highlight of the new Mi MIX4 is undoubtedly the new generation of under-screen camera technology. According to the official introduction, it adopts the first “micro-diamond arrangement” to reduce the sub-images while maintaining the number of pixels and the RGB ratio. Cable area, reduce light occlusion, realize 100% full pixel display, resolution up to 400PPI, rich and delicate color display. Not only that, Mi MIX 4 also adds a transition zone between the CUP area and the normal display area, coupled with the DDIC tuning algorithm and color tuning strategy, which can let light pass through the gap and achieve a clear imaging effect when taking selfies. In addition, the Xiaomi Mi MIX 4 also uses an integrated lightweight ceramic body, which reduces the weight by 30% compared to the previous generation, making the phone lighter and getting a great hand feeling while still maintaining the unique touch of ceramics.
In terms of configuration, Xiaomi Mi MIX 4 uses a 6.67-inch micro-curved flexible screen with a resolution of 2400×1080 and supports 120Hz refresh rate. The first batch is equipped with Qualcomm Snapdragon 888 Plus flagship processor, supplemented by LPDDR5+UFS 3.1 storage combination. Front 20 million pixel Selfie lens, rear 100 million pixel main camera + 120 ° super wide-angle + 50X periscope telephoto triple camera, battery capacity of 4500mAh, support 120W wired, 50W wireless second charging.
Xiaomi Mi MIX 4 uses an innovative CUP full screen to hide the camera under the screen. On the 6.67-inch AMOLED slightly curved flexible screen, the camera area is made into a transparent screen. The specific implementation method is to reduce the screen lamp beads in the lens area, use micro-drills to arrange, and then reset the circuit layout, use transparent leads to improve the screen transmittance, achieve full-pixel display, and display accuracy of 400PPI.
Xiaomi said that the CUP full screen of Xiaomi MIX4 lasted 3 years, more than 100 display engineers participated, R & D investment of 500 million yuan, overcome countless technical problems, and obtained dozens of invention patents.
Mi MIX 4 supports a 20-megapixel front camera under the screen, optimized by AI image algorithm to ensure self-portrait imaging. Judging from the proofs released on the spot, the Xiaomi Mi MIX 4‘s front Selfie works well.
