Nowadays, the resolution and pixel density of the display in a mobile device are one of the main marketing points. Find out what the PPI value affects.

Recently the company Samsung Galaxy S8 and Galaxy S8+, which feature an “unlimited” screen. The display has practically no frames and has a high resolution of 2960×1440 pixels and a pixel density of 570/529 PPI, respectively. In February, at the international exhibition MWC 2017, the LG brand announced a smartphone with a similar resolution and density of 564 PPI, and Sony announced a device with a 4K screen (3840 × 2160 pixels, 806 PPI). Clearly, high-resolution displays are the future.

When choosing a smartphone, many people pay attention to screen resolution, but pixel density is often left aside. Considering the development of screen technologies and developments in the field virtual reality, the ppi value also plays a big role in the quality of the display.

What is PPI?

The abbreviation PPI comes from Pixel Per Inch (pixels per inch) and is used to describe the pixel density in all types of displays, including cameras, computers, mobile devices etc. Pixel density can be an indicator of screen clarity, but there are other aspects to consider: its physical dimensions and distance to the eyes.

If you move the screen closer to your eyes, you will be able to see the pixels. If the device is on long distance from you, the high pixel density will not be particularly noticeable. Thus, the larger the display, the lower the PPI value.

Vision standard

Typically, a person's visual acuity is measured using the Snellen test, which was invented in 1860 for medical purposes. It is important to note that with this system, the ophthalmologist was trying to identify low vision, which is a medical problem. No patient ever complained of above average visual acuity.

This means that visual acuity of 20/20 is not ideal at all. This indicator means normal vision, in which a person can read a table at a distance of 3 meters.

The myth of 300 ppi

There is a myth that a person cannot distinguish pixels at a density of 300 ppi. In 2010, Steve Jobs used this statement during iPhone presentations 4, equipped with the then innovative Retina display with 326 ppi. This is partly true, but only for those users who have 20/20 visual acuity.

According to various studies, the human eye can distinguish pixels at densities of up to 900-1000 ppi.

What does pixel density affect?

The higher the pixel density, the sharper the image you will see on the screen. If earlier this did not matter much, then with the advent of the era of virtual and augmented reality the situation is gradually changing. You hardly want to see a pixelated image around you in virtual reality mode. The higher the resolution and pixel density, the more real the image. Moreover, this can be noticeable not only when using a virtual reality headset, but also when watching movies.

To understand such important and fundamental concepts in printing as ppi and dpi, you need to understand the basics of computer graphics in general.

First, you should understand that ppi and dpi are far from the same thing and they are very conditionally dependent on each other.

So, let's start with ppi, which stands for “pixels per inch”, which means “pixels per inch”. Since the metric system of measurement is adopted in the Russian Federation, it is good to remember that 1 inch is equal to 2.54 cm (although this is rounded, in reality it is 2.5399931 cm). Therefore, for us, a photograph of 10×15cm with a resolution of 300ppi means approximately the following: a photograph with side dimensions of 10×15cm in which there are 300px per 2.54cm. Which is equal to 118px by 1cm (this can be easily calculated by dividing 300 by 2.54 - the result can only be an integer, because there is no such thing as a half pixel).

The size of a given photograph can also be specified in pixels, as is often done in computer graphics. We multiply the physical size of the photo by the number of pixels that fit in one centimeter 10cmx118px=1180px and 15cmx118px=1770px and get the photo size in pixels 1180x1770px. As a rule, people who have little understanding of computer graphics get an idea of ​​the quality of a photo based on its size in pixels, which is a misconception. Because a 100x150cm image with a resolution of 30ppi will also have a pixel size of 1180x1770px. When printing such an image, it will be impossible to view it from closer than 20 meters, probably, otherwise it will cease to be an understandable image, but will turn into a set of multi-colored square pixels.

For a file intended for printing, the physical size of the image, coupled with its resolution, is important. Therefore, it is much more correct to indicate the physical dimensions of the file in cm and its resolution in ppi (if there were a generally accepted abbreviation using cm, then, of course, it should be used).

Pixel size is an abstract concept that can only exist in the virtual space of computer graphics. For a better understanding, let's take our 10x15px image at 300ppi and downsample it to 30ppi. Now, not 118px fits in one cm, but only 11px, although the image itself remains the same size.

This indicates that the pixel size has changed relative to the centimeter. That is, now it is formed from large elements, which will affect the quality of graphics. Accordingly, the smaller the pixels, the more of them will fit into 1 centimeter and therefore the more detailed the image will be.

There is a minimum image resolution for playback on a computer monitor and a minimum resolution for printing an image. Most likely, the minimum value of 72ppi for a monitor originates from the same English inch, which consists of 12 lines, which, in turn, consist of 72 dots. One way or another, but in printing (now mainly used only in offset - printing newspapers, magazines) there is such a value as lpi (Lines per inch - lines per inch), which, in general, promises only confusion and confusion among the concepts of ppi for an ordinary mortal , lpi and dpi, which we are now observing. The name “line” is conditional and in fact is also an analogue of a point or pixel. Which gets quite confusing. Therefore, we will not touch upon the term lpi at all, since it is rarely used today in digital printing and is completely clear limited circle people who understand the processes of so-called rasterization (the main printing process from which more than 50% of printing success depends). Let's continue to talk only about ppi and dpi.

Now we are still talking about ppi - the resolution of a digital image: so, the minimum acceptable resolution for reproducing graphics on a monitor is 72ppi. All monitors have a resolution of 72ppi, so if you put your nose close to the monitor, you will be able to make out the pixels of the images. It doesn’t matter what size the monitor itself is - 15 inches or 17. It will always be 72px (in Lately monitors and screens with higher resolution began to appear - HD, FHD, UHD... This only leads to the fact that now there is no single standard for monitor resolution and that the same image on different monitors will look different in size. In any case, everything is still oriented towards 72px).

What happens when the image has a resolution greater than 72px, for example 350ppi? You will still be shown an image with a monitor resolution of 72ppi. To understand that the image has a higher resolution is possible only by changing the viewing scale. By increasing the scale of the image (bringing it closer), new details will be reproduced, previously invisible. When you zoom into an image with a resolution of 72px, these pixels will become clearly visible and the image will break up into multi-colored squares.

You can often come across this phenomenon when the resolution of an image is increased from the same 72ppi (for example, taken from the Internet) to 300ppi and asked to be printed in a large format. This demonstrates a complete misunderstanding of the term “permission” as such. There is no point in increasing the resolution of an image that was originally 72ppi. This will only increase its size many times over and when enlarged, it will produce a very blurry image instead of the pixel structure. There will be no increase in detail or quality.

When printing photographs, the minimum resolution is 150ppi. It is assumed that photographs can be viewed closely. A resolution of 150ppi when printing an image at a scale of 1:1 does not reproduce the pixel structure. However, you can often hear recommendations that the higher the resolution of the image sent for printing, the better the quality. This is a deep misconception. High image resolution only affects the computer processing time of the image before printing. 150ppi is quite enough for printing. The high resolution of 300 or more ppi, which the photograph originally had (for example, taken on a wide-format camera), is necessary primarily to increase the printing scale. For example, a 10x15cm photograph with a resolution of 300ppi can be enlarged twice to 20x30cm without loss of quality and quadrupled to 40x75cm for printing with acceptable quality, provided that the photograph is not viewed point-blank. As a result, image quality depends on the initial resolution settings. In the case of photography, camera settings. In the case of simply digital images - settings in the program for a new file. If you take a photo with a resolution of 300ppi, lower it to 72ppi, and then return it to the previous 300ppi, it will not return the same quality and detail.

Today, there are a number of applications that help sharpen low-resolution images. In particular, this can be done using Photoshop or using the most advanced program in this area, PhotoZoom Pro. The results can be truly impressive, but in any case it will be an artificial increase in sharpness, which, in fact, will not return detail to the image and, using the contrast of halftones, will create such an illusion. However, for most people this task is just right.

Now is the time to consider the question - what is dpi?

dpi - stands for “dots per inch” and translates as “dots per inch”. At first glance, the concepts of ppi and dpi are identical, especially if you remember that the term pixel refers to the minimum point of computer graphics, which, due to the characteristics of the virtual world, has the shape of a square. It seems that both concepts are talking about the same thing - dots per inch. But in fact, these concepts are in no way related to each other. To better understand the difference between them, it is best to remember that ppi as a term from computer graphics is the concept of the virtual world, and dpi is a term from printing, that is, the real world. To put it more adequately, ppi is the resolution of the digital image itself, and dpi is the resolution of the printing device. And although printing is impossible without graphics, these terms are in no way related to each other.

Once in the printing program (often these are just printer drivers), the file goes through a rasterization procedure. And in its essence it is similar to the pixel structure of digital graphics. A matrix (grid) is superimposed on the image. Here the term lpi mentioned above becomes relevant, but we will not touch on it, because for us it does not matter, if anyone is interested, you can read a good one. Then the same dpi comes into play, which characterizes the number of points applied to paper to draw one raster. That is, in this case, it no longer matters what the resolution of the image itself was in ppi - it no longer affects the dpi. dpi can be compared to the artistic style of pointolism in painting, when the image is formed from multi-colored dots. The smaller the point created, the more of them will fit per 1 inch.

The more dots that fit into 1 inch, the higher the quality of the print.

If, for example, you print an image with a resolution of 1440dpi from 40ppi on a 1:1 scale, you will get a very clearly printed image with high-quality drawn pixels that will be visible to the naked eye from a distance of 1m. On the contrary, you can print a high-resolution ppi image with a print resolution of 360dpi - the print will be blurry and grainy will be visible.

The term dpi is not the only one that characterizes the quality of a print. Also important when printing is the size of the applied drop, its shape (the more regular, the better the print), etc. With a low printing resolution (360 dpi), the density of the drops will be significantly lower and their size should be larger compared to a resolution of 1440 dpi. This will affect detail, precision and fineness of lines, as well as color saturation. Higher resolution affects printing time - more passes are required. In large-format and interior printing, print resolution is set by both equal and unequal values. For example 360×360dpi, 360×540dpi, 540×540dpi, 540×720dpi, 540×1080, 720×720, 720×1080, etc. Why this is so - I admit, I don’t understand myself. But as a rule, everyone attaches importance only to the first value and therefore there are 4 main print resolutions: 360dpi, 540dpi, 720dpi, 1440dpi.

Today you can often find in large format printing offices requirements to provide images with the resolution specified in dpi. This is fundamentally incorrect and indicates the sufficient incompetence of the printers working there. An analogy is also often drawn between image resolution and print resolution, which also indicates a complete misunderstanding of the subject. The opposite extreme is when the image has a high resolution and the customer orders a print in high resolution as well. But it makes sense to print this image in a low resolution, since this will not affect the quality of the print in any way, since the picture is, for example, simple text on a colored background, which will be clear even at a minimum resolution.

High printing resolution is relevant for halftone images (photos, drawings, etc.) The more complex the gradations and color transitions, the higher the resolution should be and the more perfect the screening procedure should be (but the screening procedure is entirely a headache for the printer, which does not concern customer).

With that, I’ll wrap up and wish you success in understanding such fundamental concepts in computer graphics and printing as dpi and ppi.

Theoretical page and calculations

The concept in question stands for pixels per inch, that is, the number of pixels per inch. Also pronounced pee-pee-ay.

It literally means how many pixels fit in one inch of the image that we see on a tablet or other technology.

This concept is also called the unit of measurement of resolution. This value is calculated using two simple formulas:
Where:

• dp– diagonal resolution;
• di– diagonal size, inches;
• Wp- width;
• HP- height.

The second formula is designed to calculate diagonal resolution and is based on the use of the famous Pythagorean theorem.

Rice. 1. Width, height and diagonal size on the monitor

To show how all these formulas are used, let's take for example a 20-inch diagonal monitor with a resolution of 1280x720 (HD).

Thus, Wp will be equal to 1280, Hp – 720, and Di – 20. Thanks to the presence of these data, we can calculate pi-pi-ai. First we use formula (2).

Now let’s apply these data to formula (2).

Note: In fact, we got 73.4 pixels, but there cannot be a non-integer number of pixels, only integer values ​​are used.

To understand how much this is in centimeters, a more common value for our area, you need to divide the resulting number by 2.54 (there are exactly so many centimeters in one inch).

So in our example it is 73/2.54=28 pixels. in centimeter.

In our example it is 73, and 25.4/73 = 0.3. That is, the size of each pixel is 0.3x0.3 mm.

Is it good or bad?

Let's figure it out together.

Is this quantity important?

Pee-pee-ay, based on the above, affects the clarity of the image that the user receives on his screen.

The higher the value of the indicator, the clearer the image the user will receive.

In fact, the larger this value, the fewer “squares” a person will see.

That is, each pixel will be small, not large, and this will make it possible not to pay attention to it at all. The value of the characteristic can be clearly seen in Figure 2

Rice. 2. The difference between indicators is less and more

Of course, no one wants to have a picture like the one shown on the left on theirs.

Therefore, when choosing such equipment, it is very important to pay attention to this characteristic.

This is especially true when you buy on the Internet and do not have the opportunity to evaluate the picture with your own eyes and understand how clear it is.

Finding an indicator in the characteristics of the same smartphone is usually easy. It is usually contained in the "Display" section. An example can be seen in Figure 3.

Rice. 3. Indicator in the characteristics of the smartphone

Important! On the Internet you can often find information that ppi is more important than, for example, resolution or diagonal and some of these characteristics should play a more important role when choosing. This is not true at all. As we can see above, all these three concepts are inextricably linked.

Advantages and disadvantages

Number of pixels per inch has a positive effect on the clarity of the picture, and, accordingly, on its quality.

It will be much more pleasant for the user to look at an image with a higher indicator.

In Figure 2, the photo on the left has 30 ppi, and the photo on the right has 300. Below is another similar example.

But this concept also has disadvantages. In particular, we are talking about the autonomy of the device.

Everything is quite simple - if the picture is clear, a smartphone, tablet or other device with a screen will not be able to work for a long time without recharging.

You can even make a simple rule: the more pi-pi-ay, the shorter the battery life.

Of course, for a PC this is not a problem, since there the monitor is always plugged in, but for some phones this can become a big problem.

Therefore, when choosing a device, be sure to pay attention not only to the number of pixels. per inch, and also per inch!

Thus, we smoothly moved on to the topic of choice.

About choosing displays

There are several rules that will help you choose the display correctly, taking into account the pixels, they sound like this:

1 Be sure to pay attention to the display type. The priority should be AMOLED, even better SuperAMOLED or OLED. Such devices will always be better than.

Let's say we come to the store and see, for example, two excellent devices - and. Their price is almost the same, the second device, by the way, is more powerful.

The specifications indicate that Xiaomi has 400 ppi (for some reason, some write 400.53, but, as we said above, there cannot be a non-integer number of pixels).

Samsung has 267 PPI and the resolution is correspondingly lower (1280x720 versus 1920x1080). The diagonal is the same - 5.5 inches.

But for some reason the picture is clearer on . And all due to the use of proprietary SuperAMOLED+ technology. You can see this for yourself if you pay attention to Figure 5.

2 Try to find an opportunity to look at all the samples you have chosen in person. You can first look at their options on the Internet, and then go to an electronics store and see how they actually display pictures. A personal view in this case is simply irreplaceable.

3 Pay attention to the battery. If we talk about smartphones, then to ensure long-term operation of the device with clear image(high ppi and/or good technology), then the battery capacity should be about 3000 mAh.

For tablets it should be even higher, since their diagonal is larger,

4 Remember: the smaller the diagonal and the higher the pixel density (the number of pixels per inch), the sharper the image. Don't deceive yourself - you won't be able to achieve a very clear picture with a huge display and a small pi-ay value. It is important to maintain a golden mean here.

5 Coverage is also important to consider. This way, matte screens will produce a less clear and saturated image, but will be more gentle on your eyes.

But glossy displays will negatively affect your eyesight, but the image on them will be much more beautiful. In this case, their ppi value may be the same.

This is mostly relevant. If you work on a computer full time or even more, it is better to go for the matte option.

All this will allow you to choose the most suitable display for yourself.

Results

ppi or pi-pi-ai is the pixel density or the number of pixels per inch of an image. To convert the figure to centimeters, you need to divide it by 2.54.

There cannot be a non-integer quantity, only a whole.

The higher you show it, the clearer and more pleasant the image will be to look at.

When choosing other equipment that contains, it is very important to pay attention to this indicator.

But it is not fundamental. It is also important to look at the technology and screen coverage.

Also, be sure to look at the battery capacity and maintain a happy medium between the number of pixels. and screen size.

When buying smartphones, monitors and other equipment that has a screen, we often hear about such a thing as ppi, but few of us can say exactly what it is and what it affects.

But in fact, this characteristic is one of the main ones when choosing.

We will tell you what the actual meaning of this concept is (after all, you can find many myths on this issue on the Internet). Go!

ppi or pi-pi-ai is the pixel density or the number of pixels per inch of an image. To convert the figure to centimeters, you need to divide it by 2.54. There cannot be a non-integer quantity, only a whole.

A high-quality image on the display is one of the most important components of any good smartphone. Dear readers, we will tell you what pixel density (PPI) is on a phone display and explain why this indicator is not always important.

Pixel Density - Why It's Not So Important!

The PPI value determines the number of pixels per inch of a device's screen. Higher values ​​make the picture clearer, more readable and of higher quality.

How PPI affects image quality

When Apple introduced the iPhone 4 to the world, it used a revolutionary “Retina” display at that time, the image quality of which could be compared to the quality of pictures in glossy magazines (300 DPI). Then the company clearly showed the whole world that high resolutions on a smartphone screen are not some kind of fairy tale, but a real reality.

On this moment, the highest DPI value (dots per inch) for a smartphone display Sony Xperia Z5 Premium. Its 5.5-inch screen supports 4K resolution (2160 x 3840) and a pixel density of 806 PPI.

Among Xiaomi smartphones, good resolution can be found in Mi Mix (1080x2040 pixels), (1080x2160 Full HD+) and Mi Note Pro(2560x1440 Quad HD).

Early research and current reality

Previously, Apple stated that 326 PPI would be enough and higher resolutions on a small display of a portable device would simply become unclaimed. Now, looking at the display new iPhone X, with its 458 PPI, it's clear that Apple has decided not to follow this philosophy anymore.

Let's be honest. The average user will notice the difference between 300 and 500 PPI with the naked eye if he holds his phone screen at a palm's length from his eyes.

Therefore, displays with a higher pixel density will indeed remain unclaimed by the majority of users, since no one will want to overpay.

Plus, if there is a high pixel density, the device has to use more resources to process the output image. Is it worth reminding that this affects the performance and battery life of the smartphone?

Despite this, we will present some significant arguments in favor of high PPI screens.

Benefits of High PPI Displays

Text is much more enjoyable to read on Full HD+, Quad-HD and 4K displays. This display provides a higher level of brightness, high-quality contrast and deeper color rendition.

High resolution allows for a wider color range. The gamma looks more natural.

Those who like to dabble with virtual reality will find many advantages of a high-density screen pixels PPI. Naturally, smartphones with low display resolutions are completely unsuitable for use with virtual reality glasses. However, devices with Full-HD resolution or higher can be used without problems in VR mode for watching movies and playing games.

Xiaomi smartphones(Xiaomi) with FullHD support:

• Mi Note 3
• Mi A1
• Mi Max 2
• Mi Max
• Mi 5 / 5s / 5s Plus / 5c
• Mi 4 / 4s / 4c / 4i
• Redmi Note 4 / 4x
• Redmi 4 Prime
• Redmi Note 3 / Note 2
• Redmi Pro
• Mi Note

Conclusion

It is obvious that manufacturers should not chase high resolutions And big amount pixels on the screen. Instead, they should consider introducing new technologies that can take image quality to the next level. new level. This is precisely the strategy that Xiaomi is now following.
