The appearance of Xiaomi Mi 14 Ultra is officially announced: equipped with a full-depth micro-curved screen, infinitely close to a straight screen

According to news on February 18, Xiaomi Mi 14 Ultra has been officially announced and will be officially released on February 22.

Just now, the official announced the appearance of the new phone for the first time, introducing the new design language in an all-round way.

The overall style still continues the previous generation, but the more controversial ladder module has been canceled and replaced with an integrated solution with better feel and visual effects. The rear camera is still a large circular module.

#The outer ring of the module is also decorated with golden rings and Paris studs, which makes the texture even better.

The two sides of the back are fully wrapped with metal frames, and the sides have larger arcs, making the grip more suitable for the palm of your hand.

The front uses the full-depth micro-curved screen first launched on Xiaomi 14 Pro, which not only has a straight screen look and feel, but also has the comfortable feel of a curved screen.

Traditional hyperboloid and quad-curved screens provide users with a good visual experience, but there are still some technical limitations.

Especially at the four corners of the screen, these traditional screens do not curve down and are still essentially straight screens.

This is because the stress in these areas is very complex. When a traditional screen is bent, a large number of micro-wrinkles will definitely form, causing the screen to crack.

In order to achieve the ideal bending effect, Xiaomi engineers disassembled and analyzed the screen mold layer by layer, and finally divided the screen into 1 million small pieces, and then analyzed them one by one The stress of each piece is found to find the place where the stress is most concentrated.

Then adjust the thickness and physical properties of the film layer at the micron level, increasing the elasticity to 1.5 times the original, and increasing the extrusion resistance to 4 times the original, achieving wrinkle-free four-corner deep bends.

After two years of pre-research, the number of screens used for verification alone reached 51,000.

The investment in such a research and development process is 18 times that of traditional hyperboloid screen research and development costs, and finally the current congruent deep micro-curved screen was achieved.
