The brife history of the LCD display

The American inventor J. Fergason created the first working liquid crystal display in 1970. Before that, such devices consumed too much energy, their operating life was limited, and the contrast of the image was on a low level. A new LCD monitor was introduced in 1971. Despite the fact that liquid crystals were discovered a long time ago, at first, they were applied for different purposes. Molecules of liquid crystals under the influence of electricity can change their orientation and, as a result, change the properties of the light beam passing through them. Based on this discovery and because of further research, it became possible to discover a connection between the increase of electric voltage and the change in the orientation of the crystal molecules to ensure the creation of the image. Firstly, liquid crystals found their application in the displays for calculators and quartz watches, and then they were utilized in monitors. Today, due to progress in this area, such screens have become very popular in desktop computers and many other devices.
