A team of engineers from Samsung Advanced Institute of Technology or SAIT is working in cooperation with researchers from Stanford University to develop a new type of screen that exceeds its accuracy 20 times the resolution of the screens currently available.
This screen, inspired by ultra-thin solar panel technology, will enable the development of televisions, smartphones, or virtual reality devices and augmented reality with screens that can have a resolution of up to 10,000 pixels per inch, and for comparison, the resolution of modern smarsmartphoneeens ranges between 400 and 500 pixels per inch. ..cording to a statement by Stanford University, the first screens produced in the laboratory showed very high quality compared to the “organic light-emitting diode” (OLED) technology currently used in televisions.
It also provides crystal clear colors with high gloss efficiency that consumes half the energy consumed by regular screens.
What is “OLED” technology?
At the heart of OLED are organic light-emitting materials, sandwiched between highly reflective, semi-transparent electrodes that allow current to be injected into the device. When electricity flows through OLED, organic compounds emit red, green, or blue lights. Every pixel in an OLED display is made up of smaller sub-pixels that produce these primary colors.
When the resolution is high enough, the pixels are seen as a single color by the human eye. OLED is an attractive technology because it is thin, light, and flexible and produces images that are brighter and more colorful than other types of screens.
But in small screens close to the eye, such as virtual reality glasses and augmented reality, the human eye may be able to see those pixels, which makes the user aware that he is looking at a screen and spoils some of the pleasure of his experience, and to treat this matter must reach the required pixel density in Virtual reality and augmented reality applications, to several thousand pixels per inch, and this capability cannot be provided by current display technologies.

From panels to screens
To overcome the problem, researchers came up with a with study recently published in the journal “Science” to thwithidea of using the latest solar panel technologies to design future virtual reality screens that will be of very high high-quality to the new ultra-high-definition technology.
The 10,000 pixel per inch resolution delivers unprecedented realistic visuals therefore ideal for all virtual or augmented reality applications. The researchers called the new type of these screens the name “OLED Metaphotonic”, or shortened “Metaphotonic”.
The study is based on research by Stanford University materials scientist Mark Brungersma, who previously worked on developing a new design for an ultra-thin solar panel that uses “optical surfaces” technology to shape the front wave of light.
The team showed that the structure of OLED screens can be completely redesigned thanks to the introduction of mirrors with nanoscale surfaces, so that the light diffuses within the components of the very thin screen “like water diffusion,” according to this researcher

New advantages and promising applications
This new architecture makes it easy to create screens with very high pixel density (greater than 10,000 pixels per inch) required in emerging display applications, such as augmented or virtual reality.
In addition to having a standard pixel density, the new “metaphor” OLED screens will also be brighter, provide better color accuracy than current screens, and their production will be much easier and cost-effective.
According to the researchers, the first tests conducted in the laboratory are promising. The new screens have a much higher color purity compared to the traditional “OLED” screens, and their luminance efficiency is twice as high.
The researchers also believe that this technology, which is already very attractive for designing new TVs and smartphones, more efficient, could revolutionize the field of virtual reality by providing virtual environments that are more accurate and pure and thus closer to reality.
- However, the new “Meta OLED” technology will not be available for use in electronic devices available in the market soon, as it is still in the research and testing stage, so it is necessary to be a little patient before being able to benefit from it.
