samsung The Galaxy S22 series smartphones were launched last month. Smartphone – Galaxy S22, Galaxy S22 Plus and Galaxy S22 Ultra – the company’s first flagship launch in the year 2022. In keeping with the tradition of the company’s Galaxy S series, the smartphones come with powerful features and specifications. Recently at a round table, Byung Duk (BD) yangVice President (R&D), samsung displayexplained how Samsung has addressed some of the major consumer pain points related to smartphone screens with the new Galaxy S22 series.
“Based on our own internal research, we heard directly from consumers that auto visibility was a primary source of frustration with smartphones. Additionally, we also know that long battery life is one of the most essential functions of a smartphone,” Yang said. He said the challenge was to find a solution to provide auto visibility without compromising on battery life. To this end, Yang said, “We increased the peak brightness of the Galaxy S22 Ultra to 1780 nits, developing a new feature called Vision Booster.” Describing the new display technology, Yang said, “Vision Booster technology uses our new algorithms to enhance a display’s outdoor visibility in direct sunlight or in situations where reflections are permanent on the display. Vision Booster will analyze the brightness contribution histogram and then remap the tone of the image to maximize color contrast.” In simple words, Vision Booster improves display visibility by “considering ambient light intensity and its effect on performance”. The result is a clear picture even under direct sunlight. Currently, the Vision Booster technology is limited to the new Galaxy S22 Ultra.
Yang also spoke about the adaptive refresh rate of the new Samsung phone. Incidentally, the refresh rates on the phones have been a bit controversial as Samsung reportedly quietly updated the specification sheets of the Galaxy S22 and its Plus variants to what it now says is the lowest refresh rate their screens can hit. That’s 48Hz, not the 10Hz that the company initially advertised. For those who aren’t sure why this matters, refresh rate numbers matter because it not only affects the content viewing experience on your phone, but battery life as well.
“Three years ago, a smartphone display kit’s refresh rate at 60Hz. That all changed when Samsung introduced its first display with 120Hz refresh rates on the Galaxy S20. Since then, we’ve got the first automatic refresh rate smartphone. Display that optimizes the screen from 120 Hz to 10 Hz depending on the context and is destroyed,” Yang said, giving a background.
Coming to Galaxy S22 Series “With the Galaxy S22 we have once again moved the needle in terms of performance by first developing advanced Panel Self Refresh Rate technology,” he added. Detailing the technology in more detail, Yang said, “The display signal must intentionally lower the refresh rate to save power from the AP to the display panel via the Display Drive IC where still images are displayed. But the limit to how much.” is low refresh rate may drop. If refresh rate is too low, we start to see flicker on screen. So to reduce refresh rate and save power we reduce the frequency of signal transmitted between speaker and display drive There are some, in the Galaxy S21. The frequency of the signal between the AP and the drive IC is also restricted by several items such as touch response time. And with the Galaxy 22 we were able to reduce the frequency of the signal between the AP and the display, Alternatively you can use ACEF refresh rate technology which will lead to greater power savings and overall smartphone performance.”
