Xiaomi, a game changer in screens technology
A screen if often taken for granted but it acts as an interface to your device. We read text, watch movies, view images, touch, swipe but where did all of this come from and how did it all come to be. In this post we will take a look at the recent advances in screen technology by taking a look at Xiaomi MI 10T Pro, the phone that currently has the fastest refresh rate screens in the industry, at 144Hz. We shall also learn what it takes to design a mobile screen these days.
Do you remember those big and heavy monitors that were on every computer desk in 1980s and 1990s or as the TV in your living room? These were called Cathode Ray Tubes (CRT) and were one of the earliest forms of electronic displays. Initially they were used as oscilloscopes before they found their way into TV applications and finally computers. The first commercial Cathode Ray TV was produced in 1934 by Telefunken company in Germany. It costs around $8000 in today's money.
If you are not aware, Xiaomi is the third largest phone manufacturer in the world. In order to save battery life, Xiaomi has a technology called AdaptiveSync which has 7 stages from 30Hz all the way to 144Hz - (30Hz, 48Hz, 50Hz, 60Hz, 90Hz, 120Hz and 144 Hz). The phone actively analyses what is being seen on the screen in order to choose the most optimum refresh rate.
Rather than forcing 144Hz no matter what you are looking at, lets say still image, 144Hz isn't doing anything for you but it is still consuming the same amount of battery life because you are refreshing more than twice per second. By lowering the refresh rate, you are also lowering the battery consumption therefore contributing to 80% more battery life. The hardware has absolutely no idea of what is happening, but the software is taking a look at what you are watching and deciding what refresh rate to use intelligently.
