We briefly recall the story of the appearance in our lives of magic luminous flat boxes that open our eyes to the world. Scientists noticed that some organic substances - liquids, which are able to create an ordered crystal lattice under the influence of a change in a factor, for example, reacting to an electromagnetic field, built molecular bonds in an orderly manner, as in a crystal.

Due to this ability, various properties were manifested, for example, ordered crystals could rotate the plane of polarization of light. If a polarized light source is placed behind a substance, then at rest the light passes through molecular bonds arranged in a certain way, and when an electromagnetic disturbance occurs, we do not see anything behind the changed structure. "Eureka!" - cried out the scientists and rushed to reduce the size of the newfound product, turning it into a cell smaller than a millimeter. Thus, the cells compiled together in the form of a rectangle turned into the first black and white liquid crystal screen, giving rise to an era of flat luminous boxes.

And if you add a spark, well, that is, colors, scientists thought? Conceived and done: painted the cells in red, blue and green, connected together, and, changing the brightness of each of them by varying the electric field, added the combined light flux of 3 cells, getting any shade of color. Thus, they created a luminous idol that attracted the attention of all mankind. And the “name to him” is not “legion”, but the display!

The big run for improved characteristics began: reducing the size of the cells, reducing the width of the current-carrying tracks that are visible on the screen by the notorious "mesh", and, as a result, the physical limit was reached. IPS technology-based screens have become the crown of the display industry. A further reduction in the size of the cells began to reduce the overall brightness of the display and the juiciness of the color shades, and a decrease in the width of the track led to an increase in marriage and the number of equipment failures. Everything? Many dropped their hands, but not the engineers of BOE Technology. They decided to encroach on the “sacred” - they sent to the landfill of history, a planar (that is, a grid of anodes and cathodes located in the same plane), a power supply circuit for controlling the cell, which has been established for decades. One small step by BOE Technology engineers towards the transition to a three-dimensional system for controlling the electromagnetic field density was a giant leap for the display industry.

Technological design changes are called the Advanced super Dimension Switch (ADS). There is also another name for this technology - FFS (Fringe Field Switching). Behind these abbreviations lies the most elegant engineering solution: if the plane has reached the limit, then go to 3D!

That's what they did at BOE Technology: they transferred the cathodes from the planar substrate to the insulating layer, which made it possible to increase the density of the anodes remaining on the substrate to control liquid crystals several times. The gap width in the assemblies of these contacts has become much smaller than that of IPS technology, which leads to the formation of much stronger edge fields covering both the anode and the area between the anodes.

This allows all liquid crystal molecules with different orientations in the cells, which are located directly above the anodes and between them, to receive the action of a multidimensional electric field, thereby increasing the efficiency of liquid crystals and the transmittance of light by 20% while maintaining low energy consumption and wide viewing angles.

Today, BOE Technology, the creator and main patent holder of ADS (ADvanced Super Dimension Switch) / FFS (Fringe Field Switching), does not stand still and continues to improve its innovative technology. The use of this technology in the manufacture of displays makes the most important optical and technical and operational characteristics excellent: wide viewing angles from all sides, rich color reproduction, high brightness, contrast, prolongs the life of the display and reduces power consumption. The combination of these parameters makes professional displays, for example, displays for EliteBoard video walls, using the BOE Technology developments, extremely competitive on the market, which can significantly reduce the cost of ownership and, due to reduced energy consumption and high resistance to bright illumination, significantly increase the range of applications.

The leading global brands use BOE Technology LCD panels manufactured by ADS / FFS for most models of their compact gadgets: PDAs, smartphones, tablets, and for professional panels of various sizes and purposes, monitors, TVs, screens, laptops. According to Sigmaintell Consulting, in 2018, BOE Technology sold 54.3 million panels for TVs and 37.3 million panels for monitors. The total supply of LCD panels amounted to 91.6 million devices. And it is no doubt, mainly due to the constant search and innovative development of its engineers, BOE Technology has already outperformed all competitors, is unconditionally recognized as the world's largest supplier of LCD panels for TVs and monitors, and is not going to give way to this high place.

Based on the best practices of BOE Technology, EliteBoard has realized the potential of new technologies in its entire product line: professional displays for video walls, interactive panels and whiteboards for education and business, professional displays of various formats, a wide range of Digital Signage solutions, specialized products for transportation, medicine and retail.
