Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

HDR display for smartphones 20.05.2015

IGNIS has introduced AMOLED display technology called True Vision Display. These displays are characterized by high contrast and refresh rate, wide color gamut and high color fidelity. True Vision Display is claimed to be the only HDR display designed for smartphones.

Introducing True Vision Display, the developer noted that the race for pixel density in smartphone displays does little for consumers, while manufacturers ignore more important parameters, such as characterizing the dynamic range. This is due to the technical ability to increase the density and the inability to expand the dynamic range.

The disadvantages of liquid crystal displays include inertia, the inability to get a good black level and a large thickness due to the backlight system. These disadvantages are absent in AMOLED displays, but the increase in brightness required for HDR leads to accelerated wear and tear and literally "burns" the image on the screen. True Vision Displays managed to get around these disadvantages.

According to IGNIS, True Vision Displays are well suited for realistic display of videos and photos, immersive games and applications of augmented and virtual reality.

You can see such a display for a smartphone at the SID 2015 event, which will be held in San Jose from June 1 to 4.
