Full color OLED WUXGA microdisplay

07.11.2021

eMagin, which specializes in developing, designing and manufacturing high-resolution active matrix OLED microdisplays for AR and VR headsets and other applications where the display is close to the eyes, has unveiled a WUXGA (1920 x 1200 pixels) resolution prototype. It uses Direct Patterning Display (dPd) technology to achieve a record high brightness of 10 cd/m000. According to the manufacturer, this is the world's brightest high-resolution full-color OLED microdisplay.

"This is a historic moment for eMagin and the industry, and our biggest achievement to date in the development of our proprietary dPd technology," eMagin CEO Andrew G. Sculley described the prototype. "Applying direct framing to displays WUXGA, we've achieved a peak brightness of over 10 cd/m000 and rich RGB colors, a 2x improvement over our standard XL microdisplays on white OLEDs with a color filter and three to four times the performance of our new XLE microdisplays , and we believe it is the world's brightest high-resolution full-color micro OLED display, and we are working with a first-tier customer company on this development, including finding ways to produce it commercially.

The illustration on the left shows the structure of a microdisplay on white OLEDs with a color filter, on the right - the structure of a microdisplay that uses dPd technology.

"The 10 cd/m000 full-color brightness is an important milestone on our journey to full-color displays in excess of 2 cd/m28 by mid-000," added Scully. "In comparison, a typical laptop monitor delivers 2 cd/m2023 brightness, and a quality smartphone is as low as 250 cd/m2.In addition, our dPd displays contain over 1000 individually addressable pixels per inch (ppi) for remarkable clarity and resolution compared to typical 2 ppi laptop screens and OLED screens. smartphones with a resolution of 2500 pixels per inch.

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 ... >>

Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

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, ... >>

Computer of the future from Intel 22.04.2006

Just recently, Intel unveiled a platform codenamed Florence, billed as the "PC of the future", and now TCL (China's second largest electronics manufacturer), Alienware, Winbook and Medion are gearing up to ship products based on Florence's innovative design and technology. Intel Viv.

In the near future, other companies will join this four. Florence, resembling an LCD monitor with a thickness of only one inch, is a complete digital entertainment center and a full-featured PC. It has a 17-inch screen, a built-in TV tuner, a remote control and a wireless keyboard that folds away into the case.

It seems that the platform has very good prospects. Information about the directions of further development of this technology is already appearing. For example, some versions of Florence will have 19" and 23" monitors.

Manufacturers also turned to Intel for help in developing an interface for wireless access to cable and satellite TV.
