20-inch AMOLED displays from Ignis

28.05.2013

Ignis Innovation, which was established in 2000 to commercialize AMOLED developments started at the University of Waterloo, announced the start of deliveries of 20-inch AMOLED displays.

The company promises to start shipping the first samples of panels with a resolution of 1296 x 768 pixels in August this year. The screens use patented MaxLife technology.

A typical problem with AMOLED, according to the developer, is "burn-in" of the image, in which the picture is permanently imprinted on the screen. The reason for this behavior lies in the instability of thin-film transistors and organic light-emitting diodes. In the case of mobile phones that are replaced by the user every couple of years, this is not critical. However, a large screen installed in a monitor or laptop requires a longer period of stable operation.

In addition, in AMOLED displays, you may encounter image heterogeneity associated with the peculiarities of the technological process. Outwardly, it manifests itself in the form of stripes, dashes and foggy areas. At the moment, the only way to deal with this phenomenon is culling.

MaxLife technology is built on the constant measurement of the parameters of each pixel of the display in order to compensate for the slightest deviations from the set values, which allows you to get a uniform image throughout the entire life of the display.

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 ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

INA260 - digital current, voltage and power meter with built-in shunt 11.05.2018

The INA260 chip from Texas Instruments allows you to measure current, voltage and power in circuits up to 36 V, 15 A. Guaranteed accuracy is provided by a 2 mΩ shunt built into the microcircuit. The internal shunt has an accuracy of 0.1% and is connected according to the Kelvin circuit, so the measurement results do not depend on the length and cross section of the conductors to the measured circuit.

The INA260 can measure forward and reverse current in both the high and low side. The microcircuit internally multiplies the measured voltage and current values and outputs the resulting power.

The ADC of the microcircuit has a capacity of 16 bits. The price of the least significant digit for the measured current is 1,25 mA, voltage 1,25 V and power 10 mW. The conversion time can be selected from 140 µs to 8 ms (8 values). A special programmable output Alert is designed to signal the end of the conversion or to warn of an overload in voltage, current or power. To reduce fluctuations in readings, you can turn on automatic averaging - from 4 to 1024 times.

The internal shunt can withstand an overload of up to 100 amps for 200 milliseconds and at least 30 amps for a minute. The INA260 operates from a single 2,7...5,5 V supply, typical consumption is 310 µA. Temperature range -40°C to +125°C.
