Dual punch-hole screen with the support of 120Hz refresh rate
After its independence, the Redmi series has obviously become a vanguard in the application of design language and technology. This time, the Redmi K30 is no exception, with an elegant double-hole full screen, which greatly increases the phone's appearance and screen share. Taking a comprehensive view of the intelligent models on the market at present, under the spring tide of the comprehensive screen, they each come up with strange tricks and eight Immortals cross the sea. This time Redmi K30 introduced the design of "hole digging screen", which is believed to have been considered from many angles of experience and beauty.
Digging screen is actually very common nowadays. The Redmi K30 puts the hole in the upper right corner. As for whether the asymmetrical design is good-looking, it is a matter of opinion. The editor just wants to say that despite the hole-digging design, the Redmi K30 looks very good with its narrow frame, rounded screen edges and high screen ratio.
The screen on the front of the Redmi K30 is 6.67 inches in size and at 20:9, it looks very slender. Due to the use of TOF packaging technology, the screen share has reached 91%. Coupled with its slender proportion and rounded frame, the Redmi K30 has a "sense of control" at first hand, and the touch-controlled area of the thumb with one hand is significantly larger. It is true that the thickness of the 8.79mm 's fuselage is not light and thin, but it does not sacrifice too much grip because of the problem of proportion.
In addition, after generations of upgrading, hole-digging technology has also ushered in an upgrade in terms of technology and durability. The Redmi K30 around the screen digging holes through a higher density of LCD support, the use of low-deformation polarizer protection, and secondary dispensing technology, can effectively avoid the yellowing problem after long-term use; and through the liquid crystal panel overall nickel plating, optimize the backlight structure, can avoid the problem of edge light leakage.
Coming to the point, the Redmi K30 uses a screen with 120Hz refresh rate, which is the first time for Xiaomi phones. This flow screen with 120Hz refresh rate supports the highest 120fps display and can display up to 120 pictures per second, far exceeding the current traditional 60Hz screen. Every second, more pictures can be displayed in the sliding of the screen, which makes the sliding of the screen more smooth. Whether it is words or games, can reduce the sense of shadow.
Through the comparison of our slow-motion video, we can clearly see that the frame rate of Redmi K30 on the right side is higher during the sliding process, and the fluency and coherence of text and pictures are better. In fact, just watching may not feel the difference, but as long as you have experienced the smoothness of the 120Hz screen, you can never go back!
Due to the use of LCD's digging screen, the Redmi K30 places fingerprint identification on the right side of the fuselage. For most right-handed users, it is as convenient as on-screen fingerprint technology. For people like me who are left-handed, it may be a little uncomfortable. Fortunately, Redmi K30 supports face recognition, but you still need to switch back to fingerprint when you pay, so the continuity is somewhat fragmented.
Just look at the front and side, in fact, the design highlight of the Redmi K30 is behind. The space on the back of the mobile phone is so large, but there are so many elements to be placed, how to arrange and combine has become the most aesthetic test. Before the release, netizens said of the official photo of the Redmi K30 that it was a bit like a "coin machine". But in fact, behind the hands, the circular design around the four pictures actually adds a bit of the charm of traditional Chinese architecture to the back of the fuselage.
Xiaomi said the design was inspired by the traditional Chinese-style circular "arch", symbolizing the concept of "round heaven and earth" in traditional Chinese culture. The back of the four cameras, respectively arranged according to size, with round embellishment, I think it is still very good-looking. In addition, the Redmi K30's back follows a perfectly symmetrical design with a bit more harmony.
Overall, the Redmi K30 has done a lot of work in terms of appearance and design. Whether it is a two-hole full screen or a 120Hz screen, Redmi is intimate to the user experience everywhere. As for whether the side fingerprints are practical and whether the four-photo arrangement is in line with your aesthetic taste, it can only be said that each radish and cabbage has its own preference.

Finally, let's take a look at macro mode. The Redmi K30 can not only Hold big scenes, but also record details at small distances. Under the premise that the distance between the phone and the object is only 3 or 4 centimeters, it can still focus and shoot the details of the object clearly.
