Microsoft to produce LCD panels?
Researchers from Microsoft Research laboratories and Washington University researchers informed about the development of new technology displays – manufactured in the screens would have a four times better than today’s LCD backlight level move and could display a perfect black.
As you know, liquid crystals, which LCD matrix consists, do not produce their own light – fluorescent lamp is responsible for that, light passes through the crystals and as a result of the activities of relevant color filters it is transmitted. The overall efficiency of transmission of light in the LCD display does not exceed 10%, which means that only 1 / 10 of light generated by the lamp is not blocked by the polarizer and color filters. The light is not a completely blocked off by the pixels, and therefore a major defect in the LCD screens is a weak contrast and difficulty in using in highly-lit environment.
A team of researchers from Microsoft’s laboratories and the University of Washington in the article published on the website Nature.com – based on the above statement – offers its own solution for the production of displays. Technology ‘telescopic pixels’, because so it is called, can allow even 36% of light.
In this technology, each pixel has two micromirrors, a “dynamic”, adapting to the electrostatic forces (basic mirror), and second – static (auxiliary). Depending on the voltage applied, the basic mirror can stop light or focus it on the mirror of static, which is tantamount to put light by the pixel. Adoption of this technology has contributed to substantial improvements in image quality (including deep black, more contrast image). The technology has to offer fast pixel response time (less than 1.5 ms), and the ability to produce high-resolution screens with “relatively cheap” materials, and to its implementation do not need to modify existing production lines matrix LCD displays.
It is not known when it can be released on the market.
