Variable refresh rate of new devices sneakily updated
Samsung Electronics is found to have quietly modified the spec sheets of its Galaxy S22 smartphones, which is scheduled to hit the market later this month in South Korea and other markets.
While disclosing the Galaxy S22 and the Galaxy S22 Plus last week, the firm marketed that the new devices offer 10-120Hz variable refresh rate support compared to their predecessor’s 48-120Hz.
Hence, observers believed that Samsung used more expensive LTPO panels for the two products instead of conventional LTPS panels used for the firm’s previous phones.
A wider refresh rate range leads to a more power-efficient display and longer battery life in similar circumstances.
For example, reading e-books at 10Hz consumes less battery power compared to 48Hz as the display does not have to refresh scores of times each second for readers of e-books.
However, experts claimed that the Galaxy S22 and the Galaxy S22 Plus did not use LTPO panels so that its variable refresh rate cannot go down to 10Hz.
The issue was first raised by Display Supply Chain Consultants CEO Ross Young in his tweet.
Then, Samsung sneakily updated the two models’ lower limits to 48Hz in their spec sheets. It also revised the press release at its newsroom site.
A Samsung official reportedly admitted that the company had updated the spec sheets of the two models as their refresh rates cannot go as low as they were initially marketed to do.
