Samsung has patented a new display technology that will offer multiple simultaneous refresh rates in different areas of the screen which essentially makes it an energy-efficient offering. The details of how the South Korean company intends to do this are not known, but it certainly appears to be the next generation of display technology. Smartphones used with a higher refresh rate, for example at 120Hz, draw more energy than smartphones with a lower refresh rate, such as 60Hz or 90Hz.
patent filed With Korea Intellectual Property Rights Information Service (KIPRIS) samsungfirst spotty By Galaxy Club, describes a “method of driving a display with multiple refresh rates” and an “electronic device that drives a multiplicity of display areas of a display with different driving frequencies”. In layman’s terms, this technology will enable different refresh rates in different areas of the screen at the same time.
A display running with a 120Hz refresh rate draws more energy than a display running either 90Hz or 60Hz (with 60Hz being the most energy efficient). With energy efficiency comes low smoothness levels which can be a problem for those who prefer smooth looking screens.
Samsung wants to offer an energy efficient solution without reducing the refresh rate. According to the company, this may be possible by applying different refresh rates to different parts of the screen at the same time. For example, areas near the notification bar may have a lower refresh rate.
It may be possible that we may see the technology mentioned in the patent, which was filed in 2021 but was published earlier this week, in the upcoming Galaxy S23 series of smartphones. Having said that, it should be noted that patent applications don’t always make their way into products. Therefore, it may be possible that we may never see this technology in our devices. Apart from this, Samsung has not revealed anything in this regard yet.
