Samsung is working on a new technology that makes smartphone screens more energy efficient.

We are talking about the ability to set different frame rates for different areas of the display at the same time. For example, the upper half displays an image at a frequency of 30 Hz, while the lower half operates at a frequency of 120 Hz. The patent even points to the possibility of dividing the screen into three zones with different frequencies.

Of course, technology will certainly have its limitations, not just the options indicated in the images. At least several controls will dictate the controller, allowing you to update different areas of the display with different frequencies. But not all the details, of course. From a practical point of view, this technology will be useful in applications where some screen areas are static, while others, on the contrary, will benefit from an increased refresh rate. The One UI interface is built so that the top area is often used much less than the bottom in settings or some native applications, so it’s more convenient to control the smartphone with one hand.

As always, this is just a patent so far, so there’s no telling when the technology will be ready and appear in mass-produced devices.
