Quad HD allowed. Separate screen space

Abbreviations and acronyms that apply to smartphones appear to be somewhat unintuitive, but if you want to know what all these numbers and abbreviations mean that such displays are used, we give you this opportunity. It is important to understand that one type of display is best suited, and what do differences in screen resolutions mean? Read our article!

If we are talking about smartphone displays, it is imperative to take into account such an aspect as screen separation. This category includes three aspects: display size (in inches), number of pixels on the entire screen, and display pixel power (pixels per square inch, ppi). Once you know the size of your screen, you can calculate how many pixels there are in a square inch. You can easily find out the ppi of your phone using Vikorist and the pixel density calculator.

Below we publish the main characteristics of the displays, and there is a stench from the separate production of the HD format or, moreover, since most current smartphones are equipped with such screens themselves. You can also pay attention to the “thread” statement, which is an indicator of the brightness of the displays.

HD

The abbreviation HD in the translation from English means “high resolution”. HD is designated for a pixel value of 1280 x 720 pixels. Regardless of how great the display is, it still lacks the same value as an HD display. You can make some notes about those we smaller screen HD format, the higher the pixel density, and, theoretically, more beautiful than the picture. So, just the presence of an HD display means little, the fragments on a 5-inch screen are displayed behind the picture holder on a 10-inch panel (guess: the display dimensions vary along its diagonal, so that involved different parties).

For example, on a 4.3-inch screen, the pixel density is 342 ppi. The 4.7-inch screen will be less powerful - at 312 ppi, although the displays will be in HD format as before. According to Apple, 300 ppi is the optimal value if the human eye is no longer able to differentiate between pixels on a large-scale display (and on a small-sized display).

Full HD

Full HD is currently the standard for screen-based displays of smartphones, although the 2K (QHD) format is gaining popularity on high-end devices, with the Oppo Find 7 and LG G3 models first commercially available QHD screens are building and moving.

Full HD display 1920 x 1080 pixels. Again, the power of pixels depends on how big the display is as a whole. For smartphones with a 5-inch screen, the pixel density is close to 440 ppi, and a 5.5-inch display is no more than 400 pixels per inch.

QHD, Quad HD or 2K

QHD is equivalent to Quad HD and quadruples the parameters of the HD format. This means that you can fit the same number of pixels as 4 HD displays into one QHD display of the same size. The number of pixels for the QHD format is set to 2560x1440. A 5.5-inch screen of this format has a pixel density of 538 ppi. To put things into perspective, the 5.5-inch Full HD display has 400 pixels per square inch.

This is often associated with a lower number of pixels, so HD is sometimes called 720p, Full HD, similar, 1080p, etc. The QHD plan is called 2K because the larger number of pixels exceeds 2000, and this situation may seem a little confusing (in fact, a similar format should be called 2.5K for greater accuracy ).

richly daily telephones great manufacturers (Samsung, Motorola, Huawei) are equipped with 2K displays in the basic configuration.

4K or Ultra HD

Similar to the 2K format, the name 4K takes its origin from the larger number of pixels. U technical plan This means 4096 pixels for 4K and 3840 pixels for Ultra HD. Although these two terms are often used interchangeably, there really is a little difference between them.

The Ultra HD screen format has parameters of 3860 x 2160 pixels, and 4K – 4096 x 2160 pixels. The difference in the value of most formats is often limited to 2160p, and the difference in pixels is obviously small, but there is still a difference.

One of the first phones with a 4K display was the Xperia Z5 Premium, produced by Sony, with a 5.5-inch screen allowed Ultra HD. The Danish manufacturer characterizes the format of this display as 4K, but in fact the term used here is Ultra HD, rather than “true” 4K. Timing is not less, the Z5 Premium has a screen density of about 806 ppi - much more than can be compared to many top-end smartphones, and even more than what is really necessary for human eyes.

Screen display trends

As soon as smartphone screens continue to increase in size, the race between phone manufacturers for 4K displays, which we had already noticed, did not end. Today, there are only two models with screens of this format, only Sony – Z5 Premium and Xperia XZ Premium. In the top segment of smartphones, a 2K display has become the norm, rather than an option with a higher resolution. This, among other reasons, may have a lot to do with the problems in terms of tension, since larger displays with more separation cause greater tension. Considering that battery life has become a hot topic of discussion these days, phone manufacturers seem to be in no hurry to get ahead of the curve. However, 2017 can entirely be rock if we care greater quantity smartphones with Ultra HD displays.

Display types

Smartphones are getting stagnant different types displays: LCD, OLED, AMOLED, Super AMOLED, TFT, IPS and other, smaller widths, for example, TFT-LCD. One of the most commonly used smartphone screens is IPS-LCD. What does this mean?

LCD

The abbreviation LCD stands for “rare crystal display,” and this name directly refers to the array of rare crystals that are illuminated by the lights. The widespread width and remarkably low versatility of LCD panels make them a popular choice for smartphones and rich others. electronic devices. LCDs also look good under a bright sunny light, since the entire display is sufficiently illuminated from below, but we cannot boast of accurate color transfer, compared to other displays that do not require a backlight Nya.

Smartphones today have both TFT and IPS displays. TFT stands for “thin fusible transistor” – a sophisticated version of the PK display, in which the active matrix is ​​embedded (such as, for example, AM AMOLED). The term “active matrix” refers to those that each pixel of the screen connects to the transistor and capacitor.

The main advantage of TFT is that it achieves low performance and higher contrast compared to conventional LCD displays. The short TFT LCD screen can be called something more Visoka Vitrata energy, a less wide-ranging look at the highest color transmission. For these reasons, there is a decrease in productivity alternative options TFT displays are now increasingly used in smartphones.

IPS literally means “planar switching”, and this technology improves on the original TFT displays to ensure better color transmission and better viewing. This involves the combination of two transistors for the skin pixel, which is coupled with more intense lighting than other types of non-LCD displays. Typically, IPS panels consume less energy than a standard TFT display.

Before speaking, there are other acronyms that can be used simultaneously with IPS letters, for example, IPS-NEO. This type of technology is patented, created by the Japanese company JDI, which is designed to overcome the need for illumination. Displays with such technology function the same as other IPS-LCD screens.

AMOLED

AMOLED stands for Active Matrix Organic Light-emitting Diode. Everything may seem to be neat, but in reality it’s not so. We were already stuck behind the active matrix in TFT technology LCD, and OLED is just a term for another thin-film display technology.

OLED is an organic material that, as the name implies, produces light when passed through a new electrical system. In addition to the RC panels that power the backlight, the OLED displays are always “switched off” until the pixels around them are charged electrically. This means that your display displays black colors with greater intensity and consumes less energy when black or dark colors are displayed on the screen. However, lighter colors on AMOLED panels consume more energy, less LCD displays with similar topics. It is significant that OLED screens are significantly more expensive than original LCD displays.

Since black pixels are darker on OLED displays, the contrast is higher on LCD panels. AMOLED screens, in addition, also have a very high refresh rate, but there are few of them that are not clearly visible in direct sunlight, when viewed from RK displays with backlights. Other factors that should be taken into account are the brightness of the screen and the disruption of the diodes (the smell is more organic). On the positive side, AMOLED displays are less durable than LCD panels, and as a result, the smell can be noticeable.

What is the difference between OLED, AMOLED and Super AMOLED?

OLED stands for “organic light-emitting diode”, and the OLED display is made of thin-sheet electroluminescent material, the main advantage of which is power generation. As you can see, there is no longer any need for lighting, and this environment consumes less energy. OLED screens are most often AMOLED screens, if they are used on smartphones and TVs.

As we already guessed, the letters AM abbreviation AMOLED mean “active matrix”, which is similar to the passive matrix OLED (P-OLED), and the latter is not as wide in smartphone displays.

Super AMOLED is the name given by Samsung to its displays, which were previously used exclusively in high-end models of devices, but have now begun to appear among cheap devices. Similarly, IPS LCD Super AMOLED paints the basic AMOLED base behind the embedded touch ball directly into the screen itself, and not on top of it. As a result, Super AMOLED panels have better readability in bright light, lower AMOLED displays plus consume less energy. As the name suggests, Super AMOLED is simply a scaled-down version of AMOLED. Additionally, it’s not just some kind of advertising gimmick – Samsung panels are periodically recognized as one of the most popular in the world.

Retina

Retina is another marketing term coined at Apple. The Retina display is not characterized by any specific feature, in addition, it is guilty of sufficient separation so that the human eye cannot distinguish pixels at normal viewing distance, and therefore The intensity is not less than 300 ppi. As we already know, Apple does not measure ppi values ​​the same way as other phone manufacturers. The specifications of the display will likely vary depending on the size and layout of the display. Apple popularized the Retina concept with the release of the model
iPhone 4, 3.5-inch IPS LCD screen with a separate size of 960 x 640, which is equal to 330 pixels per square inch.

Considering that the 5.5-inch QHD display has the same width as most top Android phones these days, and devices like the S7 Edge are equipped with 534 ppi panels, Apple has concluded that 300 ppi is more than enough . As a result, this led to the iPhone 6 Plus having a Full HD display with a pixel density of 401 ppi. iPhone 7 and 7 Plus are 326 ppi and 401 ppi consistent.

Which type of display is the best?

As we have already learned, the term is not limited by the strict definition: AMOLED is not always associated with Samsung, and Retina is not necessarily associated with Apple. The IPS LCD displays that are installed in the iPhone are manufactured by LG. Samsung has developed panels for the iPad, and not all of its accessories come with AMOLED screens. It’s not really a problem, if you ask it literally, which display is better – it’s a compromise between the pros and cons.

The essence of everything lies in the present: numbers and technical parameters deserve respect when the displays on two smartphones are equal, although the real productivity of these displays is more important. It is impossible to dim the display on the paper - then you need to study it in reality to understand whether it is cold for you or too warm, which suits you saturation, brightness, contrast, look, etc. Decide, you need to pay attention to your vikorstan and from their accounts select the main screen: if you work all day at the table, and at night you hide on the sofa, then use the RK display for daylighting, Of course, it’s not that important for you. If you spend a lot of time on the street, then a display of the expected type will suit you. Perhaps you will be able to extract a drop of energy from your battery or just mindlessly look at the bright colors and rich contrast - then take a look at the AMOLED panel.

These display characteristics are referred to in different terms, and it is important for beginners to differentiate them. At first glance, it is difficult to distinguish the term “QHD” from “qHD”, you might think that it is the same name for the display with different spellings. In fact, the displays are completely different. QHD is a shortened form of Quad HD, which is similar to the term WQHD, which indicates a separate display size of 2560 by 1440 pixels. This kind of production is larger than HD or 720p by many times, but it’s easy to think about what’s going on with 4K separate production? This article aims to help you understand the current terminology of display permissions.

QHD is separate: the stars are taken from the letter W, so why is it not corrected?

The display is available in separate WQHD or QHD formats, apparently with a 16:9 aspect ratio. Similar pages are used for viewing Widescreen content. The very word Widescreen in English has the letter W in a shortened term that is often overlooked. WQHD or QHD separate rooms are also available in 1440p. Just three years ago, the distributor was unable to release the gadget with such permission. Today, QHD displays are actively being used in a variety of flagship models, such as Samsung Galaxy S6 chi LG G4.

qHD: Pomilkov's writing QHD?

Whoever confuses qHD and QHD with permission, respectfully, and so on. As a result, the qHD split property, which means “quarter HD” and becomes 960 by 540 pixels, becomes equal to the QHD split property of 2560 by 1440 pixels. It is important that we talk about the new HD (Full HD) here. This assumption can most often be taken into account budget smartphones For example, Galaxy S4 Mini.

4K: what does it mean?

The name of the term sounds like 4K Ultra HD. This means that we are talking about separate buildings, which will increase HD resolution more than once. Doctors, since beyond HD there is a separate structure of 1920 by 1080 pixels, then it turns out that the 4K screen is equipped with 3840 by 2160 pixels. The confusion between the terms Quad HD and 4K comes down to the fact that in the first phase it is not about outside HD resolution, but 720p, while in the other phase it quadruples outside HD resolution or 1080p.

This kind of separateness in smartphones is not yet being explored, but is being actively promoted by TV manufacturers. It can’t be said that the transition to a 4K display is hard on the skin, which is why it is only gaining popularity. There is a problem with capturing 4K video, but this capability has long been present in flagship gadgets, for example, Samsung Galaxy S5 and S6, Sony Xperia Z2 and so on, but here it is necessary to clarify that it is still possible to capture 30 frames at this resolution per second. The rest of the conversation was about smartphones, it is significant that information has recently appeared that the Chinese company ZTE is preparing to release the world’s first smartphone from a 4K separate platform stu.

Let us finally set up a table compiled by the American blogger Thomas Newton. On it, the author clearly demonstrates the differences between permissions, as well as the names that are used for their purpose. It is significant that on the top row the author, having vikorized the original term QHD, allowed the letter W to begin with, so the separate publication of qHD was written with a great one.

Finally, I would like to know if this guide helped you understand the terminology of display resolutions? Have you ever heard of them before, and have you ever blamed the rogue?

I'll just talk a little about the theory. The different parts of the screen may vary depending on the device you choose. Some business owners kindly respect that the size of the screen and the separation of the monitor screen are the same. For example, the size of the screen and its maximum size is 1600 x 1200, and the user can set the size, for example, 800 x 600. Naturally, the images on the screen will be formatted according to this principle what kind of statement was made by Koristuvach himself. As a result, it turns out that the size of the screen and its separate structure are a little different. In order to achieve the perfect picture, you need to set the maximum separation that your monitor supports so that the image will be as clear as possible.

What are the different parts of the screen?

Today there is a great number of monitors and the same number of permissions. Please note that all these devices have different aspect ratios, for example: 4:3, 5:4, 16:9, 16:10 and others. The wide-screen devices are painted with a great pop, the relationship between the sides is 21:9. It’s simply not enough to use such devices these days, but they are best suited for watching films shot using the CinemaScope standard. This is directly related to the fact that if you install other separate components on such a monitor, for example, FullHD (1920 x 1080p), then the edges of the monitor will lose the wide black shadow.

If there is no doubt about the permission of the monitors, then the smells are shared among themselves, as you might guess, on related sides. The following are visible: For side-by-side 4:3 -1024x768, 1280x1024, 1600x1200, 1920x1440, 2048x1536. For 16:9 aspect ratio: 1366x768, 1600x900, 1920x1080, 2048x1152, 2560x1440, 3840x2160. For 16:10 aspect ratio: 1280x800, 1440x900, 1600x1024, 1680x1050, 1920x1200, 2560x1600, 3840x2400. The most popular resolutions today are: 1920x1080, 1280x1024, 1366x768.

It’s important to note that the more separate the screen is, the more beautiful the image itself will be, but even small and young users of such devices may have to change it to less so that they want to see more on the monitor i. As a result, your skin may be wondering what it will look like in a store before purchasing, what kind of image will be on you, and what will suit you.

Today's reading devices e-books gaining great popularity. Instead of a large number of books, you only need one analogue, whose memory card can accommodate a hundred or more works. When you choose such a device, you will change the size of the reader screen to the same size.

Instructions

A “reader” is a gadget that can be viewed on Vikor electronic copies books. It is important that the size of the screen increases the ease of reading any document or creating. It’s too big to work with similar devices, but it’s not entirely easy. Small sizes give it miniaturism, but the font of the text, which looks at each other, significantly changes. This requires an alternative.

When choosing a device for reading e-books, pay attention to the geometric size of the screen. For different models, you can have one screen size, or different sizes. The greater the number of separate buildings, the more objects that can be placed on one side. It is recommended to pay attention to the model, the screen of which exceeds 5", and the separate size is no less than 320-460. This is the standard of coverage for a comfortable view of one paragraph on the entire screen, which consists of 4-6 small propositions (rows).

Please note that some models allow you to change the font that is displayed, which essentially affects the placement of a large number of rows on the screen of a portable device. At the store you can immediately try this function and find out the font that will make the text most concise.

It’s also not a good idea to forget about manual options gadget, for example, automatic screen rotation. Today, practically, skin development is ensured by this function, starting with cameras and ending portable devices.

The availability of electronic ink technology (E-Ink) allows you to reduce the voltage at the bottom. When you look at the document again, you will note that the image has been reduced to the original sheet as much as possible. Another important advantage of this option is reduced energy consumption.

Video on the topic

Wide-format monitors are gradually disappearing from the market and other analogues. Such displays are best suited to the fact that the computer’s video card supports high-performance operation.

You will need

• - Instructions for the monitor.

Instructions

Widescreen monitors have displays whose aspect ratios are 16:9 (sometimes 16:10), rather than 4:3 like standard monitors. Such displays have more extended edges. This is especially useful when watching films with a high production value. Calculate the maximum number of pixels that can be supported by the monitor. Current devices operate in FullHD format (1920x1080 pixels). The most beautiful display is the display itself.

One of the special features of the Dell XPS 13 is its display. But do you need all these pixels?

The price is set for a lot of customers: Add Dell XPS 13 touch display Will QHD+ or standard Full HD be enough? Food needs to be taken seriously, since the display is an invisible part of your computer

Do you want to capture your satisfaction in a picture?

Ale cream from the outside looking in There are also factors that need to be discussed before clicking the “Buy” button. We’ll try to help you get in touch with them.

Price

The better the technical characteristics, the higher the price. This has happened before and the Dell XPS 13 is not to blame. If you're on a budget or just want to get the most for the lowest price, you can add this amazing display to your shopping list.

Having increased prices in the US for Dell products, we advise you that you will get more with the QHD+ or full HD version.

*Standard Display - $799-$999

* Touch display - $1,499-$1,999

This difference has a lot to do with choice. The cheapest version with a touch screen costs $1,399. This same option with a standard full HD display costs $799. Retail $600. But everything is not so simple, because computers with a touch screen are different Varti characteristics, It’s clear what we are talking about.

If price is the primary factor, then you don’t have to read further. If you don’t want to overpay $1,400, it’s better to add the option of a Full HD display.

Technical characteristics of the display screen

A QHD+ display is a non-standard feature of a computer, and this means that at the same time you get a lot of other “savours”. For example, the processor Intel Core i5 ta 8GB RAM. Compare the $799 model with a Core i3 processor, 4GB of RAM and an HD screen.

Herself best version computer with full HD XPS display May 13 Intel processor Core i5, 128GB hard drive and 8GB RAM. It costs you $1,000, and you only have the opportunity to grind out the SSD in order to be disappointed in the buyer. If you want to know a little about the twist, you can improve the device yourself.

Battery robot term

More pixels mean more energy consumption. I have a version of the XPS 13 with a QHD+ display and an Intel Core i7 processor and less than 6 years before printing the socket.

Dell says models with a separate 1080p screen will last up to 18 years on a single charge. While I can’t possibly verify the fragments, we’ll take his word for it. Perhaps, such a computer will last for a whole year longer.

The size of the battery in the middle of the XPS 13 will not change, as if you hadn’t upgraded it, so it’s “unpretentious” hardware safety pass an hour without recharging.

However, regardless of your choice, Dell has a clear battery Power Companion, which extends the life of full HD XPS 13 computers for 10 years. Power Companion outer block life for laptops. You replace the standard power supply with it, and it charges your laptop. Wherever you go, take this with you, and every day at work you will feel like your computer won’t turn on.

And yet... the QHD+ display looks stunning!

That's right. If you create any kind of content and sit in Photoshop for hours, then it’s good to evaluate this device. The display with 1080p extension is still good, but it’s impossible not to succumb to the size of a high-quality display.

Clear text, bright colors, and everything is easy to understand.

Sensory capabilities are not new to Windows 10, since they were present on Windows 8, but can be a great advantage for robots. Therefore, you should get a computer with such a display in order to use them quickly.

We pad the pouch

Everything is subject to special considerations, and we cannot say unambiguously which option to choose. If we hire you, we can give you a lot of pleasure.

What is the price - vital factor, then add a computer with a standard display. The most expensive option will cost you $400 less than the cheapest touchscreen laptop. And this is a big sum.

Also, if you plan to spend a lot of time plugged into outlets, choose an option with a smaller set technical characteristics. If you add an external life block, it will not be so expensive to keep your computer running.

If you want to enjoy the benefits of a high-split screen, do not make a purchase. I can tell by special testimony- It’s wonderful. You will never tire of marveling at anyone. Just get ready to be criticized for such a computer more pennies. Quite a lot of pennies.

Zahalom has no exact form, which is shorter. It doesn’t matter which option you choose, you’ll get the best laptop you can get. Carefully analyze all the pros and cons before pressing the trigger.
