Published

In addition to the smartphone market, Samsung is also known as a leader of various display innovations, and the foldable displays implemented in the Galaxy Fold/Flip and Galaxy Z Fold 2 are the perfect examples to understand its research and development on display technologies.

After successfully developing flexible displays, many peoples thinking about what the next big development in display technology will be. In a recent development, researchers at Samsung’s in-house R&D unit Samsung Advanced Institute of Technology have successfully melded a stretchable OLED display.

Staff researcher Yeongjun Lee, co-first author of the paper said, “We applied an ‘island’ structure to alleviate the stress4 caused by elongation.”

This organic light-emitting diode display merged with a photoplethysmography sensor into a single device to measure and display the user’s heart rate in real-time. In order to make the sensor and display stretchable, the researchers used a specially modified “elastomer”.

“The technology can also be expanded to use in wearable healthcare products for adults, children and infants, as well as patients with certain diseases,” said principal researcher Youngjun Yun, corresponding author of the paper.

By using the elastomer, the sensor, and display maintained to operate normally even without showing any performance degradation with elongation of up to 30 percent, in their test. Moreover, this stretchable OLED also continued to work stably even after being stretched 1,000 times.

Principal researcher Jong Won Chung, co-first author of the paper said, “Our research is still in the early stages, but our goal is to realize and commercialize stretchable devices by increasing system resolution, stretchability, and measurement accuracy to a level that makes mass production possible.”

Aside from the heartbeat sensor that was applied in this test case, Samsung plans to combine stretchable sensors and high-resolution freeform displays to enable users to monitor things like peripheral oxygen saturation, electromyogram readings, and blood pressure.

On the other hand, the global market share of the Chinese tech giant had reached 14% in the third quarter of this year. With 14% of total market share, Xiaomi slipped to the third rank, while it was the second-biggest smartphone vendor during the second quarter. Moreover, OPPO and Vivo tied for fourth with a 9% market share.

Canalys Principal Analyst, Ben Stanton. “The smartphone industry is striving to maximize production of devices as best it can. On the supply side, chipset manufacturers are increasing prices to disincentivize over-ordering, in an attempt to close the gap between demand and supply. But despite this, shortages will not ease until well into 2022.”

Google now lets users to continuous scrolling on its Search for mobile

Published

Continuous Scrolling is relevant to social networking sites that people want to keep in their app/website. Whether Instagram, Twitter, or Facebook – they all offer continuous scrolling to stay in touch for as long as possible.

Now, Google wants you to constantly scroll through search results on your mobile search page. The company says the new change will make “browsing search results much easier and more accurate.”

From the description Google provided on its blog, it looks like Search on mobile will show results that are more closely related to open-ended questions such as “What to cook with potatoes?” instead of simply showing you results from the second search page.

It is well known that after the first page of search results, clicks drop dramatically. If you are not on the first page or two of the Google Search Engine (SERP) results page, you will probably never get eyeballs at all.

Google now wants to remove that barrier so that when you reach the bottom of the search results page on your phone, the following results will be automatically loaded with relevant information. You will find more information related to your search now.

According to the company, “most people who want more information tend to search for up to four pages of search results.” With the latest updates, mobile users can browse seamlessly to many different outcomes before clicking the see button. This new change will be gradually released in more English searches on mobile in the U.S.

T-Mobile won against its rivals AT&T and Verizon in several major 5G categories 

Published

on

T-Mobile takes the lines of victory now, after a new report by the independent statistics company Opensignal found that T-Mobile had won several key 5G categories in competition with its rivals AT&T and Verizon.

T-Mobile first entered the comparative record measuring the three leading 5G companies for availability, access, download speed, and loading speed in the United States. Verizon has hit T-Mobile without the 5G video, voice app, and gaming experience – AT&T was completely shut out and went home with a beautiful shiny star.

According to the October 2021 Opensignal report, T-Mobile users saw an average 5G download speed of 118.7 Mbps, which was twice as fast as AT&T or Verizon. This marks a 35.6% increase over the numbers Opensignal used in its July 2021 report. T-Mobile’s lead would have been less impressive with 5G upload speeds, up to 16.1 Mbps compared to Verizon’s 14.4 Mbps and AT&T’s 9.7 Mbps.

However, T-Mobile also increased its winning limit on 5G access and access, which found that T-Mobile users spent more than a third of their time, 34.7%, on active 5G network gaming, unlike AT& T users ’16 .4% and Verizon’s 9.7%. T-Mobile’s 5G access, as represented by the number of sites visited by a user with a 5G signal, hit 7.2 on a 10-point scale, ahead of AT&T’s 4.9.

AT&T telecommunications received a headline in the Opensignal July report as well. The company is still in the game, but much will depend on what AT&T looks like when it finishes spinning its own entertainment into its own company. Currently, the Opensignal image is one where AT&T can be freely accused of doing too little to prepare for 5G releases, which is not consistent across the U.S.
