Modern devices are equipped with screens of various configurations.The key at the moment are displays based on liquid crystals, but they use different technology, in particular the case of TFT and IPS, which differ in a variety of settings, though are descendants of one of the invention.
Now there are so many terms that refer to certain technologies, hiding under the abbreviations.For example, many may have heard or read about or IPS TFT, but few people understand what is really the difference between them.This is due to the lack of information in the catalogs of electronics.That's why it helps to understand these concepts, as well as to solve, TFT or IPS - Which is Better?
Terminology
to determine what would be better or worse in each case, it is required to find out, for what functions and tasks meets every type of matrices.IPS on the fact of a TFT, more precisely, its species, which has been used in the manufacture of certain technology - TN-TFT.Consideration should be given more details of these technologies.
Differences
TFT (TN) is one of methods of producing arrays of liquid crystal screens, i.e. screens TFT in which the elements are arranged helically between the pair of plates.In the absence of energization they will be facing each other at right angles in the horizontal plane.Maximum voltage causes the crystals to turn so that the light passing through them led to the formation of black pixels, and in the absence of voltage - white.
Considering or IPS TFT, the first from the second difference is that the matrix is made on the basis of that described earlier, but the crystals therein are not located helically and parallel to the common plane of the screen and to each other.Unlike the TFT, in this case, crystals do not rotate in the absence of stress.
As we see it?
If you look on IPS and TFT screen, the visual difference between the two is the contrast that provides almost ideal transfer of black.On the first screen, the image will look clearer.But the quality of color reproduction in the case of TN-TFT matrix can not be called good.In this case, each pixel has its own color tone different from the others.Because of this the colors are strongly distorted.However, there is a matrix and dignity: it is characterized by the highest response rate of any currently existing.For IPS screen it takes some time, during which all parallel crystals will make a full turn.However, the human eye detects nearly no difference in the response time.
Important features
If we talk about whether it is better to use: IPS or TFT, it is worth noting that the first are more energy intensive.This is due to the fact that for rotating the crystal is required a considerable amount of energy.That is why, if the manufacturer before the task is to make its energy-efficient device, it is commonly used TN-TFT matrix.
If you choose Screen TFT or IPS, it is worth noting the wider viewing angle of the second, namely 178 degrees in both planes, it is very convenient for the user.Other types of matrices have been unable to provide similar.And one significant difference between the two technologies is the price of products based on them.TFT-matrix at the moment are the most cost-effective solution that is used in the majority of low-end models, and IPS refers to a higher level, but it is not a top-end.
IPS display, or TFT choose?
first technology allows to get the maximum quality, sharp image, but requires more time to turn the use of crystals.It affects the response time and other parameters, in particular the rate of discharge of the battery.Level color TN-matrices are much lower, but their minimal response time.The crystals were then arranged in a spiral.
In fact, you can easily notice the incredible chasm as screens, working on the basis of these two technologies.It concerns and cost.TN technology is on the market only because of the price, but it can not ensure a juicy and vibrant picture.
IPS - this is a very successful continuation in the development of TFT-LCDs.The high level of contrast and viewing angles are quite large - it is an additional advantage of this technology.For example, a TN-based monitors are sometimes black color itself changes its color.However, high energy consumption of devices operating on the basis of IPS, forcing many manufacturers to resort to the use of alternative technologies or to lower the rate.Most often, the matrix of this type occur in wired monitors that do not work on battery, allowing the device to be not so volatile.However, constantly being developed in this area.
