One of the new features that Samsung has brought its new flagships is the Always On display which as its name suggests, is always active it allows us to check the time, notifications and other alerts without waking the phone. How does this happen?
The Samsung Always On Display (AOD) was a function screen developed by Samsung to meet a great need: to see important information quickly without having each time to click on the screen. How do without affecting battery consumption?
The main secret: Super AMOLED screen
The fact that Samsung devices have AMOLED screen facilitates the implementation of the Always On feature since the advantage of this technology is that black pixels in an AMOLED are off and therefore consumes less energy.
There are other components such as IC Driver (something like the display driver for LED), the application processor and various sensors still consume much energy, specifically the Driver IC is what most consumes.
In order to carry out the Always On, Samsung has reduced energy consumption at rest to a fifth of what was previously consumed mode. Also applies intelligent power saving, a new hardware algorithm that improves the performance of Driver IC.
Thanks to all these changes, the Korean company has been able to separate the energy required for the IC Driver in normal mode and you need the Always On screen stays at the hardware level. So that we understand, it says Samsung is as if the driver of a vehicle traction choose between two wheels or four to optimize driving depending on road.
The rate of energy consumption varies depending on the information that users want compromise.decide the Always On screen. Simple information need only eight colors. If you want something more complex, such as customization options that Samsung offers, come into play more than 16 million colors because the Depths of bits increases and it needs more power.
Reducing the frame rate
Reducing the frame rate also saves energy compared to a normal mode smartphone, the Always On feature reduces the number of frames per second, which is understandable considering that the Always On screen shows less information.
Its proximity sensors accelerators, detect when the phone is in a pocket or bag and off the screen, these sensors also adjust the screen brightness to the lighting conditions.
As you can see behind the Always On feature much effort and technological innovation. Make this feature work seamlessly took about three years. What do you think?
