New Concept liquid crystal display technology

Existing backlit LCD technology can not completely blocked , leading to not display all black , hindering the improvement of contrast . In the use of light , the liquid crystal polarizer behind 50 percent of the light will be blocked , and then the color filter will block 30% , leading to the final utilization of less than 10% .
According to Microsoft and Washington State University scientists recently published in the journal Nature papers, new technology allows lcd graphic display true black and greatly increase the contrast ; while the backlight utilization increased four -fold , to make the display brighter. In addition, the technique can use the existing LCD production line manufacturing , the cost is not too high.
Specifically, the technology called "telescopic pixel" stretching of pixels, each pixel by the sides of the main structure composed of a small mirror . Was similar to the shape of the primary mirror of annular discs , diameter of 50 microns , the intermediate pore size of 20 microns . And a second small mirrors are located just behind the orifice diameter of 25 microns. The mirrors in opposite directions , light reflected by the primary mirror , the secondary mirror illumination , imaging revealed through the hole . When in the closed state, the primary mirror is flat , the light irradiation on the secondary mirror can not , will not have any light revealed that to achieve full black. To display a color which , in the main mirror electric charge applied , bent bowl , focus on the secondary imaging lens through hole .
Allegedly, this technology not only completely solve the problem of a full black display , and light utilization rate reached 36 percent , much higher than today's LCD 9% efficiency. Power on the primary mirror deformation time is very short response times can be achieved 1.5ms.
Although in the current era of high definition , in a panel installed on millions of small mirrors looks very weird. But research people still said that this principle display panel can not only achieve high resolution, and the use of raw materials are very inexpensive , and can be in the current lcd module production process through the transformation of mass production.
