Smartphone manufacturers are always looking for new ways to reduce power consumption and thus extend the battery life of their devices. Samsung is developing a new monitor that should do just that. Other manufacturers can benefit from this as well.

Samsung variable refresh rate display

We’ve known about OLED screens with variable refresh rates for a number of years. In the past, it was only possible to lower the refresh rate from 120 to 60 Hz very easily. In the meantime, there are several possible intermediate steps and it can even go down to 1 Hz as with the Galaxy S22 Ultra (tested). So if almost static content such as images are displayed, a display does not have to run at 120Hz and consume a lot of power. Samsung now wants to go one step further and be Extend the variable refresh rate to parts of the smartphone screen (source: Galaxy Club).

According to a patent that has now appeared, the display can individually select the refresh rate used, depending on the region. Apps like YouTube can take advantage of this. Where the video plays at up to 120fps, the Samsung screen will also display 120Hz. For example, in the presence of the title and comments, the screen can operate at 30 Hz or less. anyway The entire screen does not have to operate at 120Hz and thus can save energy.

There are of course many uses for such a display. The entire content of a smartphone rarely works at 120Hz. If fewer are needed, they will be able to save a lot of energy in everyday life. Samsung’s patent Steps of 30, 60 and 120 Hz are listed. In the future, levels could be more accurate. It would be the first generation of such a display.

New screen for Samsung Galaxy S23?

It’s entirely conceivable that this new display from Samsung will actually be used in the Galaxy S23, although we’re probably expecting the Galaxy S24. So far it was just a patent and it is not entirely certain whether the ideas will actually be implemented. But it would be conceivable here and Samsung would once again have a useful unique selling point. At the same time, Samsung is also a display contract manufacturer and can also supply it to other manufacturers.
