Next week, Xiaomi will release the Redmi K60 series of smartphones. We have said many times that Redmi passes the same way Xiaomi did. We mean from a company that makes cost-effective handsets, Redmi is going to turn into a firm that designs premium phones. Although, initially, Xiaomi’s idea of running a dual-brand strategy had a quite different goal. Today, we learned that the entire series of K60 smartphones would sport 2K straight screens.
Redmi K60 2K screen
In fact, TCL and Redmi have been working on such a screen for more than one and a half years. The entire process has gone through 5 batches of verification, more than 60 kinds of design verification, and tens of thousands of system driver debugging. Finally, they reach mass production.
The difficulty of making 2K screens lies in the sharp increase in the number of pixels, which puts forward extremely high requirements for the design and manufacture of the underlying circuit. The thinnest metal wire on this screen is only 1.5um. Also, the precision error of evaporation should be smaller than 1/10 of the diameter of a hair.
In terms of parameters, this 2K screen has almost no shortcomings. It not only has 2K high resolution but also has 1400nit peak brightness, 12bit color, P3 color gamut, diamond-like arrangement, 526PPI pixel density, and primary color professional-grade color accuracy. The color difference is only about 0.29.
The screen also supports 1920Hz PWM dimming, Dolby Vision, HDR10+, and HDRVivid certification. Thus, it has all the top-end parameters available on the market.
In other respects, this screen will also use C6 luminescent material, color accuracy ΔE≈0.29, JNCD≈0.24, and support hardware-level low blue light. It is certified for low visual fatigue.
In terms of software, Redmi has self-developed a full-link display engine and ultra-dynamic display technology, rebuilding the algorithm architecture from dimensions such as color calibration, color mapping, color gamut coverage, and spatial brightness, and making precise pixel-by-pixel adjustments.
What’s more important for Xiaomi, everything was developed and manufactured in China. The producer is TCL, which uses a 6th-generation AMOLED production line. This is also the first 6th-generation AMOLED production line in China.
