This afternoon, Xiaomi announced on its official Weibo account (the Chinese Twitter) that it has introduced two very important new exclusive technologies on its latest flagship, the Xiaomi 12 Pro. These are the Xiaomi Smart Dynamic Refresh Rate Technology and the protection mode. natural eye.
Xiaomi 12 Pro receives two new exclusive technologies that improve the display
But let's start from the basics, the Xiaomi 12 Pro uses a second generation LTPO (low-temperature Polycrystalline oxide) screen with a refresh rate of 120 Hz and a resolution of 2K +. The brand claims that the LTPO material allows the screen to actively reduce the refresh rate when needed to save in power consumption. This is a hardware feature, but it also requires the cooperation of the software that Xiaomi calls “Smart Dynamic Refresh Rate Technology”.
Ideally, for vertical scrolling of lists, the optimal refresh rate would be set with Shift / Frame to a constant value, i.e. the longer the swipe, the more frame rates are needed.
In real situations, in order to ensure that the vision does not block, the Smart Dynamic Refresh Rate Technology present on the Xiaomi 12 Pro will increase the frame rate to 120Hz as the user's finger touches the screen, and will gradually reduce the refresh rate As the scrolling speed of the list decreases, the refresh rate drops to 10Hz before the animation ends.
It is worth noting that the Xiaomi 12 Pro is the only model in the Android field that has the ability to quickly decrease the speed during a swipe. To achieve this, Xiaomi needs to modify the ScrollView and ListView in the native Android controls to increase the ability to calculate the scroll speed.
In this process, one has to find the best place to change the frame rate. If you act too early it will cause visible lag, if you act too late, you won't save energy.
After examining user behavior, Xiaomi realized that some scenarios do not require very high refresh rates, such as low frame rate animations, low frame rate videos and input methods. When the system detects these scenarios, it can actively reduce the screen refresh rate to save power.
In browsing and reading scenarios, many times the screen is still, so you can reduce the refresh rate to 10Hz or even 1Hz to greatly save power consumption.
As for the safeguard of our sight, the Xiaomi12 series is equipped with a more intelligent eye protection mode, this mode no longer adopts a "one size fits all" approach, but makes different adjustments for different colors.
Taking the CIE color space as an example, the color with most blue light components is the area between pure blue (0, 0, 255) and pure white (255, 255, 255). Although other colors also have blue light components, the proportion is low. Therefore, Xiaomi has to treat the different colors differently so that the most harmful blue light can be reduced without affecting the hue of the other colors.
So this natural eye protection mode on the Xiaomi 12 series allows you not to strain your eyes and at the same time maintain color accuracy.
Finally, remember that the Xiaomi 12 series also has other features of another level such as support for Dolby Vision, dimming at 10.000 levels, supports HDR video with a peak value of over 1000 nits and has passed the DisplayMate A + certification. On paper it is the best screen ever seen on a Xiaomi smartphone.
