The matrix is the main part of the laptop. Thanks to it, all processes in the laptop are launched. Two sheets of flexible material sandwiched with a liquid crystal substance are responsible for the laptop's workflow. For these reasons, the cost of a matrix installed in a laptop is very high. For reference: the new matrix will cost you more than the rest of the laptop combined.
The matrix plays an important role in the functioning of the laptop. It consists of two sheets of flexible polarized material, between which there is a layer of liquid crystal solution. Touching the screen during operation can displace the liquid, it will start moving.
The nature of liquid crystals is such that they are in a transition state between solid and liquid. The molecules of a substance in this form retain their crystal structure, but at the same time they have fluidity.
Liquid crystals used in matrices have come a long way to perfection. In laptops, an active matrix is used - the pinnacle of the evolution of liquid crystal matter. It is produced using TFT (Thin Film Transistor) technology. This type of matrix is used in laptop computers.
All matrices of modern laptops are divided into three groups. They differ in the arrangement of the crystals relative to each other. This affects the transmission of light and determines the basic characteristics of the base unit of the laptop.
The first invented a technology called TN (Twisted Nematic - English twisted nematic). Crystals of such a matrix are organized like a twisting spiral. This technology is not suitable for accurate color reproduction and is not used in its original form. Contrast and response time are also far from ideal. The vertical viewing angles of TN matrices are so imperfect that even the smallest deviation leads to a complete change in the pixel color.
Next came the advanced matrix technology - TN + Film. The TN-matrix is covered with a special film that makes the viewing angle wider. Horizontally, the viewing angle of a conventional TN matrix is only 90 degrees, while the improved version is 140 degrees. But vertically, the situation has hardly changed.
The need arose to create a better technology. It was proposed by Hitachi. ISP (In-Plane Switching) technology, or SuperTFT, allows you to create matrices with a viewing angle of 170 degrees, both vertically and horizontally. Their peculiarity is that the crystals are parallel to each other. The brightness and contrast of monitors in laptops with such a matrix reaches 300: 1.
