Samsung: We solved two of the most important ache factors of smartphone shows with Galaxy S22 collection


Samsung Galaxy S22 collection smartphones launched final month. The smartphones — Galaxy S22, Galaxy S22 Plus and Galaxy S22 Extremely — are the corporate’s first flagship launch of the 12 months 2022. Preserving with the corporate’s Galaxy S collection custom, the smartphones include highly effective options and specs. At a current spherical desk, Byung Duk (BD) Yang, vp (R&D), Samsung Electronics, spoke about how Samsung has addressed a number of the main shopper ache factors associated to smartphone screens with the brand new Galaxy S22 collection.
“Based mostly on our personal inner analysis, we heard immediately from customers that the auto visibility was a major supply of frustration with smartphones. Moreover, we additionally know that lengthy battery life is likely one of the most important capabilities of a smartphone,” stated Yang. He stated that the problem was to discover a resolution to supply auto visibility with out compromising battery life. For this, Yang stated “We elevated the height brightness of the Galaxy S22 Extremely as much as 1780 nits, developed a brand new characteristic known as Imaginative and prescient Booster.” Explaining the brand new show know-how, Yang stated, “Imaginative and prescient Booster know-how makes use of our new algorithm to boost the out of doors visibility of the show in direct daylight or conditions the place reflections are everlasting on the show. The Imaginative and prescient Booster will analyze the brightness contribution histogram after which remap the tone of the picture to maximise the coluor distinction.” In easy time period, Imaginative and prescient Booster improves show visibility by “contemplating the sunshine depth of the environment and its affect on the show.” The result’s a transparent image even beneath direct daylight. Presently, the Imaginative and prescient Booster know-how is restricted to the brand new Galaxy S22 Extremely.
Yang additionally spoke about Adaptive refresh fee of the brand new Samsung telephones. By the way,the Refresh Charges on the telephones have been bit controversial as Samsung reportedly quietly up to date the specs sheet of the Galaxy S22 and its Plus variant, which now says that the bottom refresh fee that their screens can hit is 48Hz, not 10Hz that the corporate initially marketed. For these unsure why this issues, the refresh fee numbers matter because it not solely impacts the content material viewing expertise in your telephone but additionally impacts the battery life.
“As early as three years in the past, the refresh fee of a smartphone show equipment at 60 Hertz. That each one modified when Samsung launched our first show with 120 hertz refresh charges on the Galaxy S20. Since then, we launched the primary automated refresh fee smartphone show which optimize the display from 120 Hertz to 10 hertz relying on the context and take part destroyed,” stated Yang giving a background.
Coming to the Galaxy S22 collection he stated, “With Galaxy S22 we’ve got moved the needle as soon as once more when it comes to show efficiency by growing the primary superior panel self refresh fee know-how.” Detailing the tech additional, Yang stated, “The show sign is intentionally from the AP to the show panel by the show drive IC to save lots of energy the refresh fee must be minimized the place nonetheless photos are displayed. However there’s a restrict for a way low the refresh fee can go. If the refresh fee is just too low, then we began to see flickering happen on the display. So to lower the refresh fee and save energy we lower the frequency of sign transmitted between the speaker and the show drive, one thing there within the Galaxy S21. The frequency of the sign between AP and drive IC can also be restricted by a number of objects similar to contact response time. And with Galaxy 22 we have been in a position to lower the frequency of sign between AP and the show utilizing different can ACEF refresh fee know-how which is able to result in higher energy saving and total smartphone efficiency.”
