Samsung is preparing to release flexible displays

25.11.2012

In the first half of 2013, Samsung intends to start mass production of the so-called flexible displays. With a plastic backing, they are stronger, lighter, and cheaper than modern displays that use glass as a base. Samsung Display is preparing to mass-produce displays with a plastic base instead of glass, which will make devices stronger, lighter and even more flexible, according to the Wall Street Journal, citing a source familiar with the situation.

The displays will be based on OLED technology, meaning they will use LEDs. This technology is used in displays for Samsung's flagship smartphones and is gradually beginning to be introduced into TVs. OLED technology allows the construction of thin panels that, using plastic as a base, can be bent without destroying the electronics. In addition, such panels are lighter in comparison with modern panels, which are based on glass.

The development of flexible OLED panels has been going on for the past few years. In addition to Samsung, Japanese companies Sony, Sharp and Korean LG Display participate in it. For example, Sony Corporation has been in this field since 2002. Two years ago, Sony showed off a 4,1-inch flexible LED display that it developed. However, there are no commercial devices based on such displays yet, due to technological limitations in mass production.

"Samsung's main goal is to use plastic instead of the traditional glass substrate to create shatterproof displays. This technology can also help reduce product costs and differentiate products in the market," said Lee Seung-chul, an analyst at Shinyoung Securities.

The WSJ writes that Samsung Display is currently in the final stages of developing flexible displays. It is planned to release them on the market in the first half of 2013, and the company expects to become their first manufacturer. Samsung Display Vice President Lee Chang-hoon said the company is shipping test samples of flexible displays to several of its partners today. However, he could not name the exact date for the release of the first products based on them, since it has not yet been determined. Previously circulated information that the Samsung Galaxy Note II will be equipped with a flexible display.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Mobile phones are not associated with brain tumors 09.04.2022

Scientists from the University of Oxford, together with colleagues from the International Agency for Research on Cancer, investigated the question of whether mobile phones are somehow associated with brain and eye tumors. It may seem strange to some that this is still being discussed somewhere. Nevertheless, oncology from a mobile phone remains an indestructible topic that is resurrected every time, as we are informed about the next step forward in telecommunications (now the emergence of 5G, the fifth generation of mobile communications, has turned out to be such a step forward).

In 2011, the International Agency for Research on Cancer reported that cell phones can cause brain tumors, but most of the subsequent epidemiological studies did not confirm this, and mobile phones were recognized as safe. But if there is a "majority" of studies, then there is also a "minority" - with different results? Other results here are often related to the fact that for analysis they take the medical history of people who already have a cancer diagnosis. These are so-called retrospective studies, and their problem is that they look where there is light: in principle, there are more people in the world who use mobile phones than those who do not, and guess which of them will be more among those who had a brain tumor.

The authors of the new work acted differently: they performed a prospective study in which they analyzed whether a tumor would appear in the future in initially healthy people. The analysis used medical data from approximately 776 women born between 1935 and 1950. In 2001, they filled out special questionnaires to assess how actively they use their mobile phones, in the sense of how actively they talk on mobile communications when the phone or smartphone is pressed to the head. (Although we all have different days in terms of social saturation, everyone can still estimate how many times a day he or she speaks on the phone on average, how long the conversation lasts on average, etc.) Half of those surveyed in 2001 were surveyed on the same topic of cellular activity again in 2011 to see if there had been any change. And these data were compared with medical information that covered another fourteen years after the second "cellular" survey.

In general, surveys have shown that among older women there are enough of those who do not speak on mobile phones (for example, among those who were from 2011 to 60 in 64, 25% did not talk on mobile phones). In the fourteen years after 2011, of all of them, only 0,42% developed brain tumors - and there was no connection with mobile phones: those who used them had tumors with the same probability as those who used them did not use. In this sense, there were no differences related to the type of tumor or its location, that is, tumors in the temporal parts of the brain did not occur more often than in any other, if again considered in connection with talking on a mobile phone.

True, it is worth clarifying that of those whose data were analyzed in the study, only 18% talked on the phone for more than half an hour a week. So there is still to be explored any special mobile talkers who are ready to talk for hours, and every day. At the same time, with the development of instant messengers, it will certainly not be easy to find a sufficient number of such people. It would also be good to include men in future studies. With regard to age, malignant tumors still develop more often in the elderly than in the young, and, in addition, the connection between brain tumors in children and adolescents has actually already been looked for - and they came up with the same results as now.
