Samsung: We fixed two of the biggest smartphone screen problems with the Galaxy S22 series

Samsung The Galaxy S22 series smartphones were launched last month. Smartphones — Galaxy S22, Galaxy S22 Plus and Galaxy S22 Ultra – are the company’s first flagship launch for the year 2022. In keeping with the tradition of the company’s Galaxy S series, the smartphones are packed with powerful features and specifications. At a recent roundtable, Byung Duk (BD) yangvice president (R&D), Samsung screenexplained how Samsung solved some of the major consumer issues related to smartphone screens with the new Galaxy S22 series.
“Based on our own internal research, we’ve heard directly from consumers that automatic visibility is 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 automatic visibility without compromising battery life. For this, Yang said “We increased the maximum brightness of Galaxy S22 Ultra up to 1780 nits, developed a new feature called Vision Booster.” Explaining the new display technology, Yang said, “The Vision Booster technology uses our new algorithm to improve the screen’s outdoor visibility in direct sunlight or in situations where there are permanent glare on the screen. The Vision Booster will analyze the brightness contribution histogram and then remap the image tone to maximize color contrast.” Simply put, Vision Booster improves display visibility by “taking into account the intensity light from the environment and its influence on the display”. The result is a clear image even under direct sunlight. Currently, the Vision Booster technology is limited to the new Galaxy S22 Ultra.
Yang also talked about the adaptive refresh rate of new Samsung phones. Incidentally, refresh rates on phones have been a bit controversial as Samsung has reportedly quietly updated the spec sheet for the Galaxy S22 and its Plus variant, which now states that the lowest refresh rate their screens can achieve is 48Hz, not 10Hz as the company originally announced. For those who don’t know why this matters, refresh rate numbers matter because they not only affect the experience of viewing content on your phone, but also battery life.
“Already three years ago, the refresh rate of a smartphone display kit was 60 Hertz. That all changed when Samsung introduced our first display with 120 Hertz refresh rates on the Galaxy S20. Since then , we have introduced the first screen auto-refresh rate smartphone which optimizes the screen from 120 Hertz to 10 Hertz depending on the context and participates in the destruction,” Yang said while giving an overview.
Come to the Galaxy S22 series he said: “With the Galaxy S22, we have once again moved the needle in terms of display performance by developing the panel’s first advanced self-refresh rate technology.” Further detailing the technology, Yang said: “The display signal is deliberately from the AP to the display panel via the display drive IC to save power, the refresh rate should be minimized where still images are displayed. But there is a limit to how low the refresh rate can go. If the refresh rate is too low, then we started to see flickering occur on the screen. So to decrease the refresh rate and save power, we decrease the frequency of the signal transmitted between the speaker and the display player, something there in the Galaxy S21. The frequency of the signal between the AP and the drive IC is also limited by several things 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 screen by using an alternative ACEF refresh rate technology that will drive to greater power saving and overall smartphone performance.”
