The researchers were able to triple the density of liquid crystal displays
The group of researchers, which include experts from AU Optronics and JNC Petrochemical, managed to develop a technology that allows to increase the density of LCD screens to reduce power consumption.
The increase of density especially in demand in displays for VR headsets, where the potential modern technology has been exhausted, and the acceptable quality level has not been reached yet.
To measure the achievement allows the following fact: the density of the Retina displays Apple is approximately equal to 500 pixels per inch, and the new technology will produce displays with an index of 1500 pixels per inch for the same size display.
A prototype of such a display is first shown by Samsung in 2008, but for mass production technology proved to be unsuitable. Now the developers managed to resolve the issue and open the way to commercialization.
The secret of the new displays — in the absence of subpixels and color filters. All the pixels are alternately lit red, blue and green, which currently has lighting. The switching is very fast (much faster than modern displays). In other words, mixing the three basic colors, through which is formed a full color image, new displays does not occur in spatial and time domain. The lack of filters allows to reduce the power consumption at the same brightness by about 30%.
