Main types of monitors. Types of modern monitors

The Monitor as a visual display of the information is old and in its history has experienced several revolutionary changes. If not a few years ago, manufacturers mainly fought for the ability to provide high basic characteristics of “pictures”, today tougher competition between different concepts of implementation of this device. Modern types of monitors differ in many criteria, ensuring not only quality images, but also the availability of communication interfaces, energy efficiency, functionality and other performance.

What distinguishes the monitor from the TV?

At first glance, modern monitors for computer equipment are no different from TVs. At least if you compare small models of similar size, the difference can not be overlooked. And yet here it is. So, if classic TV – it is a standalone device that receives and plays audio and video from cable and satellite stations, the monitor is hardware processing and presentation of graphic information, the source of which is a special card. As for external differences, they are most clearly expresses the type of the monitor on the laptop which can be represented by one of the matrices of the family of liquid crystal displays. In particular, today the common formats of the matrices TN, MVA and state of the art development – IPS. Compared to the same TVs, these modules provide more quality and detail of reflection of image information per unit area of the screen.

Types of matrices for computer displays

The Basic module, which is balanced by characteristics and so widespread, is TN. This system provides a good response time, an average of 20 MS, and has a low cost of manufacture. But because of the modest performance of color and low-contrast matrices is not in demand among discerning connoisseurs of high-quality images. The best replacement of such devices are the modules IPS and TFT-type monitor that has a decent contrast, not released dead pixels and translates the best color at high viewing angles. But the TFT module in modern versions is more expensive and requires higher energy consumption.

Classification reflected information

There are two fundamentally different concepts of information output to the screen as an image. The classic is considered an alphanumeric system, which is implemented in the display processing of a character or a text signal. Among the latest varieties of this family deserves the attention of the so-called smart display, endowed with editorial skills and pre-processing of the obtained data. The second method of reporting information – the graphics, which, in turn, is also divided into two groups. In particular, there are vector and raster monitor types with their features. For example, a raster output designed just for the computer equipment with the appropriate graphics. Vector displays are more often used in radars, slot machines and other equipment requiring high quality reflection graphic data.

Classification

The oldest to date is the monitor working with cathode-ray tube. Is the screen CRT, which already practically do not occur on sale. To traditional and also aging can be attributed to LCD monitors. There are different types of LCD monitors on liquid crystals. This is the same matrix that is used in equipping laptops – the most modern include the modules IPS and TN+film. In the General family of screens is the most advanced LED technology, based on light-emitting diodes. Such models of monitors offer high image quality and in some versions show a good energy saving abilities. Technologically more perfect continuation of this concept is OLED monitor that uses the organic light-emitting diode.

Classification interface

In our days, it makes sense to talk about the two types of interfaces that have the largest share – analog VGA and HDMI system, which although is not new, but provides high quality transmission “pictures” and sound. The VGA port is the last representative of the analog interfaces. On the background of a digital TV broadcast signal it is noticeably inferior in quality but still used for the sake of maintaining the usual functions of technology in terms of connection. As for HDMI, it is, in fact, is adapted for an appliance, the DVI-D interface that is designed to process multichannel audio. Today, this connector can be equipped with any type of monitor and projectors and plasma televisions. To implement the connection on this channel, you must use a passive adapter system DVI-D. however, note that not all analog outputs even, theoretically, allowthe ability to connect via HDMI and using an adapter.

Classification of the type of video card

Every monitor needs a system processing the input signal. This feature further perform stream adapters that allow multiple configurations for the connection. In particular, some video cards require a PCI or AGP, which provide high efficiency and operational flexibility. Another option is to connect the group of chips of the graphics core, which is embedded in the charge. This solution is cheaper and involves no hassle in use, but it is inferior to the previous version in terms of the same efficiency and performance. Modern computer monitor often are equipped with complete integrated video card. This option is even cheaper, but again, does not allow to maximize the potential of the input signal.

Classification by type of coverage

There are two types of coatings for monitors – matte and glossy. The first option is good because it allows incident light to be reflected, but is characterized by less high rates of reproduction. Glossy models, in contrast, provide a more rich and vivid picture, but the reflection glare can be a nuisance in terms of visual perception. Evaluating these types of monitors, do not forget about the practicality of caring for them. For example, on a matte surface does not remain traces and divorces, which is not the glossy cover.

General features

Performance parameters of the monitor determine how comfortable the perception of “pictures”. The first is to note the resolution that is in the newest models is 2560x1600. Color depth determines how saturated the image. On the market practically, there are monochrome models, but the version in the latest collections at least a 32-bit matrix. Almost all the standard types of monitors operate at a frequency in the range of 60-100 Hz. Increasing this figure reduces the effect of flicker during the broadcast, which increases the comfort during viewing. Of course, the value and size of the monitor. Today you can find small sized models on 17-20 inches, and the screens are 30-40 inches.

Selection Criteria monitor

Besides the basic characteristics, you should consider the functionality of the monitor, its ergonomics and the availability of additional accessories. The functionality model have different range settings, special modes, special features energy-saving operation, etc. Evaluating what type of monitor is better for a particular task, it will be useful to define and implement the interface. In this case, select the most convenient way for the same settings – via the menu display or by means of mechanical controls on the housing. As for additional accessories, they mostly refer to the elements of the fastener. The better brackets, racks and the retaining panel, the greater is the stability of the entire structure.

Manufacturers

The leaders of the segment are manufacturers, such as BenQ, ASUS, DELL, Samsung, etc the Developers of these firms strive to master not only the basic technological areas in terms of improving the image quality, but put emphasis on the specificity of the interaction of the monitors with the other components of the computer. The middle class represent brands level Hitachi, Philips and SuperSonic. Under the brand names of these manufacturers produce all types of monitors from LCD to the latest models on the platform of the OLED. And if the technological excellence of this product may yield the aforementioned leading companies in terms of price it has the advantage. For example, the average characteristics of the monitor can be purchased for 10-12 thousand rubles, while similar operating parameters offers the ASUS or BenQ are about 15-18 thousand At the same time, popular budget segment, which try to present their developments and bonus, and the little-known company. In this group you can find the model of modern monitor with a price tag of about 5-7 thousand

Conclusion

Segmentation of monitors in classes and types as the new developments becoming more complex and vague. Subtypes appear in a seemingly well-established segments - LCD and LED monitors. Two popular versions acquire different modifications, endowed with new functions and improved properties for ergonomics. In particular, modern types of monitors have been switched to digital interfaces are gradually being implemented with promising support playback format 4K and appear frequently in touch performances. Of course, does not stand still and improvement of the basic principles of performance. In this respect, the greatest interest among producers causes a logical platform LED and continues the system already with their OLED tech modifications.
