First 4K display for smartphones

16.04.2015

Sharp has introduced the first Ultra HD smartphone display on the market with a resolution of 2160 x 3840 pixels. The pixel count of the new screen is four times that of the standard Full HD display in the Android smartphone market and 2,25 times that of the Samsung Galaxy S6 (2560 x 1440 pixels).

The new Sharp display has a diagonal of 5,5 inches. It is made using IGZO semiconductor material (Indium Gallium Zinc Oxide) and has a record pixel density of 806 pixels per inch in the mobile display market. For comparison, the pixel density of the Samsung Galaxy S6 is 577 pixels, while the Apple iPhone 6 is 326 pixels per inch.

The company plans to start mass production of the new display in 2016. The first smartphones with the new display are also expected to go on sale next year, writes PhoneArena.

We add that Sharp has long been one of the suppliers of displays for Apple devices. According to sources, Sharp's IGZO screens will be used in the new 12,9-inch iPad Pro, which has yet to be announced.

Some foreign media have taken it upon themselves to suggest that the new Sharp display will be in the next generation of iPhone. However, it is worth emphasizing that only the improved iPhone 6s and iPhone 6s Plus are expected to be released next year. Previously, when updating devices, Apple never increased the resolution of their screens.

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Implanted brain stimulator 30.04.2024

In recent years, scientific research in the field of neurotechnology has made enormous progress, opening new horizons for the treatment of various psychiatric and neurological disorders. One of the significant achievements was the creation of the smallest implanted brain stimulator, presented by a laboratory at Rice University. Called Digitally Programmable Over-brain Therapeutic (DOT), this innovative device promises to revolutionize treatments by providing more autonomy and accessibility to patients. The implant, developed in collaboration with Motif Neurotech and clinicians, introduces an innovative approach to brain stimulation. It is powered through an external transmitter using magnetoelectric power transfer, eliminating the need for wires and large batteries typical of existing technologies. This makes the procedure less invasive and provides more opportunities to improve patients' quality of life. In addition to its use in treatment, resist ... >>

The perception of time depends on what one is looking at 29.04.2024

Research in the field of the psychology of time continues to surprise us with its results. Recent discoveries by scientists from George Mason University (USA) turned out to be quite remarkable: they discovered that what we look at can greatly influence our sense of time. During the experiment, 52 participants took a series of tests, estimating the duration of viewing various images. The results were surprising: the size and detail of the images had a significant impact on the perception of time. Larger, less cluttered scenes created the illusion of time slowing down, while smaller, busier images gave the feeling of time speeding up. Researchers suggest that visual clutter or detail overload can make it difficult to perceive the world around us, which in turn can lead to faster perception of time. Thus, it was shown that our perception of time is closely related to what we look at. Larger and smaller ... >>

Vector network analyzer up to 26,5 GHz from Rohde & Schwarz 03.02.2021

A new product from Rohde & Schwarz is the R&S ZNH, a complete two-port handheld network analyzer with AFT/antenna analysis and full S-parameter measurements. Both of these functions are available in the basic version. The R&S ZNH is easy to operate, highly configurable and compact, ideal for field testing.

The R&S ZNH is a handheld vector network analyzer that allows you to identify faulty RF cables and communication system components. The R&S ZNH can also measure microwave components in the laboratory and in the field up to 26,5 GHz. The R&S ZNH is a reference instrument for standard measurement tasks such as cable and antenna analysis and full two-port S-parameter measurements. The analyzer has built-in receiver step attenuators on both test ports, which prevents them from possible overload. The R&S ZNH four-receiver architecture supports the Unknown Jumper Calibration Method (UOSM). Best-in-class RF performance and analyzer features such as low path noise (0,0025 RMS), 100 dB dynamic range, 0 dBm output power, and 16001 measurement points make the R&S ZNH ideal for launching and maintaining communication and research systems microwave components.

Additional R&S ZNH options such as power measurement, pulse measurement, absolute power measurement and power ratio measurement allow you to perform maintenance and repair work on radar or satellite systems. These possibilities are opened in the network analyzer by entering a special digital key that can be entered by the user himself.

The analyzer's weight of only 3 kg., small size, no active cooling, long battery life and easy-to-use, even with gloves, instrument keys make the R&S ZNH an ideal instrument for field work. The 7-inch multi-touch screen works with gesture support similar to modern smartphones, which reduces the time of work and intuitively increases the speed of getting used to the device interface. Also in the analyzer there is a function of the assistant for setting up and configuring the measuring setup. The free InstrumentView and MobileView software allows you to immediately transfer the received information in the field to the laboratory for simultaneous analysis.

On top of all this, the R&S ZNH handheld analyzer is perfect for design offices, production lines and educational institutions with a limited budget and lack of space to place the instrument when measuring components such as filters, amplifiers, RF cables, adapters and antennas.
