Researchers have found a way to triple the resolution of current displays

A team of researchers from the Central Florida University developed a new surface that allows you to customize the individual subpixels of the display. Potentially this means that the resolution of LCD TV panels can triple with minimal costs in record time.

Technical details were published in Nature. In fact, the researchers found a way to control subpixels using voltages. Each pixel of the LCD screen consists of three subpixels. Each of them is responsible for one of three colors: red, green or blue. The white backlight shines through the pixel, while the electronic shutter controls the subpixel's visibility. For example, if the pixel should be blue, the shutter will close the red and green subpixels. To get the violet, the shutter will close the green. The backlight determines the brightness of the color.

The team of researchers presented a method using nanostructural embossing and reflecting aluminum, allowing completely to abandon subpixels. On the test device, the researchers were able to control the color of each sub-pixel - instead of showing only the blue, now the subpixel displays all the colors that the TV can display. Since each subpixel now performs pixel operation, in almost the same method of display production, the resulting resolution is tripled. Moreover, the brightness also becomes significantly higher.

Now it remains to scale the process and imagine that it will be able to work with the current production lines. If this happens, then in the next couple of years we can expect a sharp jump in the resolution of displays, while the price should not change significantly.
