Screen type

The technology by which the matrix of the laptop is made.

Matrices of the TN+film, IPS and *VA types are most widely used nowadays; less common are screens like OLED, AMOLED, QLED, miniLED, as well as more specific solutions like LTPS or IGZO. Here is a more detailed description of all these options:

— TN-film. The oldest, simplest and most inexpensive technology currently in use. The key advantages of this type of display are low cost and excellent response time. On the other hand, such matrices are not of high image quality: brightness, colour fidelity and viewing angles of TN-film screens are at an average level. These indicators are quite enough for working with documents, web surfing, most games, etc.; however, for more serious tasks that require a high-quality and reliable picture (for example, design or photo / video colour correction), such screens are practically unsuitable. Thus, TN-film matrices are relatively rare nowadays, mainly among low-cost laptops; more advanced devices are equipped with better screens, most often IPS.

— IPS (In-Plane Switching). The most popular type of matrix for laptops in the middle and top price range; however, it is increasingly common in low-cost models, and for trans...formers and 2-in-1 devices (see "Type") it is almost a standard option. Screens of this type are noticeably superior to TN-film in terms of the quality of the “picture”: they provide a bright, reliable and rich image that hardly changes when the viewing angle changes. In addition, this technology allows to achieve extensive colour gamuts in various special standards (see below) and is suitable for creating displays with advanced features such as HDR support or Pantone / CalMAN certification (also see below). Initially, IPS matrices were expensive and had a slow response time; however, nowadays, various modifications of this technology are used, in which these shortcomings are fully or partially compensated. At the same time, different modifications may differ in practical characteristics: for example, some are created based on the maximum reliability of the picture, others differ in affordable cost, etc. So it's ok to clarify the actual characteristics of the IPS screen before buying — especially if you plan to use a laptop for specific applications where image quality is critical.

— *V.A. Various modifications of matrices of the "Vertical Alignment" type: MVA, PVA, Super PVA, ASVA, etc. The differences between these technologies are mainly in the name and the manufacturer. Initially, matrices of this type were developed as a compromise between IPS (high-quality, but expensive and slow) and TN-film (fast, inexpensive, but modest in image quality). As a result, *VA screens turned out to be more affordable than IPS and more advanced than TN-film — they have good colour reproduction, deep blacks and wide viewing angles. At the same time, it is worth noting that the colour balance of the picture on such a display changes somewhat when the viewing angle changes. This makes it difficult to use *VA matrices in professional colour work. In general, this option is designed mainly for those who do not need perfect colour accuracy and at the same time want to see a bright and colorful image.

— OLED. Matrices based on the so-called organic light-emitting diodes. The key feature of such displays is that in them each pixel is a source of light in itself (unlike classic LCD screens, in which the backlight is made separately). This design principle, combined with a number of other solutions, provides excellent brightness, contrast and colour reproduction, rich blacks, the widest possible viewing angles and a small thickness of the screens themselves. On the other hand, laptop OLED matrices for the most part turn out to be quite expensive and “gluttonous” in terms of energy consumption, and they wear out unevenly: the more often and brighter a pixel glows, the faster it loses its working properties (however, this phenomenon becomes noticeable only after several years of intensive use). In addition, for a number of reasons, such screens are considered poorly suited for gaming applications. In light of all this, sensors of this type are rare these days — mostly in individual high-end laptops designed for professional colour work and with appropriate features such as HDR support, wide colour gamut and/or Pantone / CalMAN certification (see below).

— AMOLED. A kind of matrices on organic light-emitting diodes, created by Samsung (however, it is also used by other manufacturers). In terms of its main features, it is similar to other types of OLED matrices (see above): on the one hand, it allows you to achieve excellent image quality, on the other hand, it is expensive and wears out unevenly. At the same time, AMOLED screens have even more advanced colour performance combined with better power optimization. And the low prevalence of this technology is mainly due to the fact that it was originally created for smartphones and only recently began to be used in laptops (since 2020).

— MiniLED. Screen backlight system on a substrate of miniature LEDs with a size of about 100-200 microns (µm). On the same display plane, it was possible to increase the number of LEDs several times, and their array is placed directly behind the matrix itself. The main advantage of miniLED technology can be called a large number of local dimming zones, which in total gives improved brightness, contrast and more saturated colors with deep blacks. MiniLED screens unlock the potential of High Dynamic Range (HDR) technology, suitable for graphic designers and digital content creators.

— QLED. Matrices on "quantum dots" with a redesigned LED backlight system. In particular, it provides the replacement of multilayer colour filters with a special thin-film coating of nanoparticles. Instead of traditional white LEDs, QLED panels use blue ones. As a result, a set of design innovations makes it possible to achieve a higher brightness threshold, colour saturation, improve the quality of colour reproduction in general, while reducing the thickness of the screen and reducing power consumption. The reverse side of the QLED-matrices coin is an expensive cost.

— PLS. A type of matrix developed as an alternative to the IPS described above and, according to some sources, is one of its modifications. Such matrices are also characterized by high colour rendering quality and good brightness; in addition, the advantages of PLS include good suitability for high-resolution screens (due to high pixel density), as well as lower cost than most IPS modifications, and low power consumption. At the same time, the response speed of such screens is not very high.

— LTPS. An advanced type of TFT-matrix, created on the basis of the so-called. low temperature polycrystalline silicon. Such matrices have high colour quality, and are also well suited for screens with high pixel density — in other words, they can be used to create small displays with very high resolution. Another advantage is that part of the control electronics can be built directly into the matrix, reducing the overall thickness of the screen. On the other hand, LTPS matrices are difficult to manufacture and expensive, and therefore are found mainly in premium laptops.

— IGZO. An LCD technology that uses a semiconductor material based on indium, gallium, and zinc oxides (as opposed to more traditional amorphous silicon). This technology provides fast response time, low power consumption and very high colour quality; it also achieves high pixel densities, making it well-suited for ultra-high resolution screens. However, while such displays in laptops are extremely rare. This is explained both by the high cost and by the fact that rather rare metals are used in the production of IGZO matrices, which makes large-scale production difficult.

Code name

The code name for CPU installed in the laptop.

This parameter characterizes, first of all, the generation to which the processor belongs, and the microarchitecture used in it. At the same time, chips with different code names can belong to the same microarchitecture/generation; in such cases, they differ in other parameters - general positioning, belonging to certain series (see above), the presence / absence of certain specific functions, etc.

Nowadays, the following code names are relevant in Intel processors: Coffee Lake, Comet Lake, Ice Lake, Tiger Lake, Jasper Lake, Alder Lake, Raptor Lake (13th Gen), Alder Lake-N, Raptor Lake (14th Gen), Meteor Lake (Series 1), Raptor Lake (Series 1). For AMD, the list looks like this: Zen 2 Renoir, Zen 2 Lucienne, Zen 3 Cezanne, Zen 3 Barcelo, Zen 3+ Rembrandt, Zen 3+ Rembrandt R, Zen 2 Mendocino, Zen 3 Barcelo R, Zen 4 Dragon Range, Zen 4 Phoenix Zen 4 Hawk Point. Detailed data on different code names can be found in special sources.

Passmark CPU Mark

The result shown by the laptop processor in the Passmark CPU Mark test.

Passmark CPU Mark is a comprehensive test that is more detailed and reliable than the popular 3DMark06 (see above). It checks not only the gaming capabilities of the CPU, but also its performance in other modes, based on which it displays the overall score; this score can be used to fairly reliably evaluate the processor as a whole (the more points, the higher the performance).

Monitors connection

The maximum number of monitors that can be connected to a laptop at the same time and shared.

Simultaneous connection of several screens allows you to expand the visual space available to the user. For example, it can be useful for designers and layout designers when working with large-format materials, for programmers to separate tasks (one monitor for writing code, the second for searching for the necessary information and other auxiliary purposes), and for gamers-enthusiasts — to ensure the maximum immersion effect.

LAN (RJ-45)

Laptop LAN interface version.

LAN (RJ-45, colloquially “twisted pair”) is standard connector for wired connections to computer networks. The version of this connector is identified by the maximum data transfer rate that it supports. In practice, in most cases, 100 Mbit/s is quite enough, however, the development and cheaper technology has led to the fact that more and more laptops are equipped with 1 Gbit/s LAN; such connectors are used even among budget devices. And the most advanced version found in modern laptops is 10 Gbit/s. Mostly gaming models are equipped with such interfaces: high speed, among other things, reduces lag (latency) in online games.

Security

This paragraph may specify the availability of special digital and physical security features: fingerprint or face scanners, TPM security module, Smart Card reader and kensington/noble lock. Here is a detailed description of these features:

— Fingerprint scanner. Fingerprint recognition device. Almost the only way to use this function is to authenticate the user — during the initial boot or unlocking of the laptop, when logging into an account, when confirming payments, etc. This authorization method is convenient because the fingerprint is always at the user's disposal, his it is impossible to forget, lose or accidentally "surrender" to an attacker, like a normal password; and forgery of a print, although possible, is very difficult. Also note that some laptops with this feature allow you to memorize several users and automatically recognize them “by touch”.

— Face scanner (FaceID). A specialized scanner for facial recognition. Note that this is not just about “recognition by photography” (any webcam is capable of this — with the appropriate software), but about full-fledged three-dimensional scanning using a special IR sensor. This allows you to achieve very accurate and reliable recognition — face scanners often surpass fingerprint sensors in these indicators. And thanks to advanced...algorithms, accuracy is maintained even when facial hair changes, putting on and taking off glasses, and other such changes. The weak point of this function is the recognition of twins, as well as children under 13 – 14 years old, who have not yet had time to form enough individual traits. As for the application, the main purpose of FaceID is to authorize the user when logging in and various accounts, making payments, etc. Separately, we note that support for this authorization method is built into Windows Hello, a biometric recognition system built into Windows 10. However, the data from the scanner can also be used for other purposes, sometimes quite original — for example, to animate a three-dimensional muzzle on the screen, copying the user's facial expressions.

— Kensington / Noble lock. The presence of a slot on the laptop case for a special security lock. Such a lock is usually used to fasten a strong metal cable, the other end attached to a fixed or heavy object. Thanks to this, theft "on a jerk" and other similar attempts to steal a laptop become almost impossible. This feature is especially useful if the device is in the public domain, such as on a display stand in an electronics store. Note that Kensington and Noble are two different types of security locks and are not mutually compatible. And the socket on the body can be designed for either one of these standards, or both at once; this point should be clarified separately.

— TPM security module. A module designed to encrypt information stored on a laptop is the so-called cryptoprocessor. Such a module stores the keys for decoding encrypted data, it is also responsible for the encryption/decryption process itself. At the same time, TPM allows you to "close" the file so that it opens only on a specific device — for example, on a laptop on which it was originally encrypted. This feature is unlikely to be required in domestic use, but it can be indispensable in the business area, where you have to deal with confidential data.

— Smart card slot. A device for reading contact smart cards — plastic cards with built-in microchips. It is convenient to use such cards as user identifiers and/or access keys to protect confidential information. Note that an NFC (see above) can become an alternative to this function — it also allows you to read smart cards, only contactless ones. However, contact readers are somewhat cheaper, and they are also considered more reliable and secure. So such equipment does not lose popularity among business and professional laptops; and some models are equipped with both an NFC and a slot for smart cards.

Backlight

The presence of backlight in the laptop keyboard. This feature not only gives the device a stylish look, but also makes the keys more visible than in non-backlit laptops. The specific functionality of the backlight can be different, it depends both on the price category and on the general purpose of the laptop. For example, single-color lighting is found both in low-cost laptops and in ultrabooks for professional use. And game models can provide advanced RGB lighting and even the ability to sync backlight.

The backlight colour is usually chosen by the manufacturer, taking into account the general specialization of the laptop. So, white backlighting is popular in “office” devices — it fits well into a discreet business style and at the same time looks good on its own. Yellow (golden) colour is much less common — mainly among fashion laptops, although there are exceptions. In turn, among gaming models, the most advanced kind of backlighting is often found — RGB: it allows you to choose a shade as you wish, besides, a colour change can signal various game and system events. A number of top gaming laptops feature 4-zone RGB backlighting on the keyboard, or even custom per-key backlighting that makes the...buttons visually stand out from the rest. Gaming devices are also being produced with simpler, solid-colour backlighting systems — in such cases, the keyboards usually glow red, green or blue. It is these shades that are best combined with the characteristic design of gaming laptops; at the same time, the red glow is usually used in devices with a rather catchy and “aggressive” appearance (and in itself is an important element of this style), while blue and green are typical for a more restrained design.

Additional keys

The number of additional keys provided on the laptop keyboard.

Additional are called keys that do not belong to the standard set and perform various specific functions: calling the browser, controlling the media player, switching power and cooling modes, etc. Such equipment facilitates quick access to certain settings and applications. On the other hand, additional keys require additional space, and there is not much of it in laptops; in addition, some specific functions can be implemented through the Fn key, pressed simultaneously with one of the standard buttons. Therefore, this function is relatively rare in modern laptops, mainly among gaming models.
