Artificial mechanical display technology displays colors as real

The array of thousands of tiny 'super-glasses' controlled by artificial mechanics will help the TV screen display true color as true.

This is the result of Swiss researchers. This device, called electron diffraction grids, can be controlled with the ability to self-adjust to light to produce a full spectrum of colors on the screen. This is something that current technology cannot do yet.

The team of research experts confirmed that the device can be used to produce computer monitors with the same resolution as high-end LCD monitors.

' The current display technology can only reproduce a range of colors ,' said Manuel Aschwanden, an expert at the Swiss National Institute of Technology Research. ' The most striking feature in our new technology is that it can display all colors '.

Limit of technology

Current screen technologies - such as TV screen technology cathode, LCD and plasma screens - recreate colors based on the three main light elements of red, green and blue. Other colors are reproduced by combining the above basic colors. Take for example the yellow color created by combining red and green.

In order to display complex images, this display technology needs to combine thousands of different color dots on the screen. Each different screen type has a different way of doing this. For example, LCD screens are split into thousands of individual pixels (pixels). The pixels are divided into 3 categories according to the colors of red green and blue with filters. Replacing the brightness of each color spot can create different millions of shades for displaying images.

However, technology like this will not be able to show all the colors we see in the real world. This is most evident when they re-appear as images of the sky. ' Every time you take a photo and upload it to your laptop you see the color of the sky is never the same as reality ,' Aschwanden said.

Even the most modern screen does not display true color.

The problem with current display technology is that combining three basic colors is used to reproduce different colors on the screen. Green, blue and red by the manufacturer of the selected screen will determine all other colors displayed on the screen. Therefore, each different screen displays colors differently. This is sometimes very small but sometimes the difference is also very large.

But the Swiss researchers' new technology is not limited by the three basic colors system.

Instead, researchers have successfully developed a more flexible approach to using the full spectrum of colors that human eye can recognize.

To accomplish this, the team of researchers developed a device called diffraction grating - similar to shutters. The diffraction layer is not a new technology. This technology has been applied in projector and fiber optic cable systems.

However, the new diffraction layer was invented by Swiss researchers unlike the class being used. The new mesh is made of flexible polymer material. This is a flexible and elastic material like rubber used to make artificial muscles in robots. These muscles will work when an electrical source is applied.

When there is a white light stream from a LED (Light Emitting Diode) into the diffraction layer, it will be separated into different colors with full spectrum similar to the color of the rainbow. And by using different power sources to manipulate optical muscles, the diffraction grating will expand or shrink, allowing the rotation of the light to be shifted.

Different colors can be separated by spectroscopy by using very small opaque holes on the surface of the diffraction mesh. Changing the power source running through the artificial muscles will help different color spectral sections pass through the correct holes.

On the screen of the above technology application, there are many different diffraction layers placed behind the pixels (pixels) that allow the combination of colors to create the most realistic colors.

Perfect technology

Now the team of researchers has successfully produced a 400-layer diffraction layer that can be used in high-resolution displays.

Researchers are currently working on improving the technology and especially reducing the amount of electrical energy needed to control artificial muscles. The first step to controlling artificial muscles requires thousands of volts of electricity. However, that number has now dropped to 300 volts.

And with the improvement of technology, Aschwanden expert believes that new technology can be applied in many different fields.
