True tone technology: what is it

True Tone technology appeared in Apple devices not so long ago. The first time it was introduced in the iPad Pro. Today, True Tone is present in iPads, and in iPhones and even in macbooks. In this article we will tell you what True Tone is, why it is needed and how to turn it on. The main thing is not to confuse True Tone with Night Shift, these are two completely different technologies, and at the end of the article we will tell you why.

True Tone is a technology that changes the screen temperature depending on external illumination. With the help of special sensors in real time, the device monitors the indicators and adjusts the balance of white on the screen. If you take a simple sheet of paper and an Apple device with True Tone and place them in one environment, you will notice that they will be approximately the same shade. Place in another. too. If you turn off Truiton and try to repeat the experiment, the difference will be obvious: the screen was so and remains regardless of lighting. You need to understand that it does not change brightness, the balance of white changes.

In the picture above, Truetone is clearly visible under the surrounding lighting. In a room with a warm yellow light, the screen receives a warmer tint, and on the street with natural solar lighting the screen becomes more white.

Why do you need True Tone

As you could already guess, True Tone imitates the properties of a regular sheet of paper. Depending on illumination, white light can be felt in different ways. Tempon just regulates white balance so that the color temperature of the screen corresponds to the surrounding lighting. So the screen looks more natural.

First of all, Truetone is designed to read text and sewg on the Internet. By the way, if you are afraid that you will feel discomfort from the fact that the screen becomes “yellow” or vice versa “white”, then we hasten to reassure. You will not notice any difference until you hold a device with True Tone in your hands. As soon as you turn it off, you will immediately want to return it back, since most likely the original white balance will shine too much into the eyes. The same with Night Shift technology, but we will say about it a few words at the end.

Restoration of True Tone and Autonomousness on the iPhone after replacing the display

Restoration of True Tone on iPhone. A fairly common reason for contacts in the service center. In most cases, the reason for the inoperability of the function of labor tone is an unskilled replacement of the screen. The fact is that if the iPhone screen (starting with the iPhone 8 model) changes to a new one, then in order for the True Tone function and auto.yanging on the new display works, it is necessary to calibrate the new screen.

How is the restoration of True Tone on iPhone done

Since the True Tone sensors in the iPhone operate together with the display controller. Therefore, if True Tone stopped working after replacing the screen, it is necessary to calibrate it (firmware of the controller), which is performed using a special programmer and specialized software.

Retina displays with or without or without, which is better?

Screens with the convention of “Retina” appeared on Apple smartphones in 2010 (IPhone 4 model), and after 2 years, in 2012, MacBook began to be equipped with similar displays. Also, all modern iPad, Apple Watch, IMAC and other technique use these screens. Another technology called True Tone appeared with the iPhone 8 model, later it migrated to Mac (since 2018) and Apple Pro Display XDR monitors and monitors. Let’s figure out how these technologies are different.

Retina translates from English as “retina”. Apple used this term as a marketing move, drawing an analogy with a retina of the human eye. In simple words, retina is a screen with so much pixels that the eye does not distinguish between individual points. That is, the image looks as clearly and monolithic as possible. Two parameters are used to measure effectiveness. PPI. the number of pixels per inch. And ppd. pixels for a degree. The last parameter means how tightly the pixels are displayed when looking at the display at an angle.

What is True Tone technology?

Unlike the term Retina, which indicates the density of the screen (resolution) of the screen, True Tone is automatic adjustment of the white balance on the display. Depending on the illumination, the colors and contrast of the screen can be distorted. For example, the image will not be contrasting, with a yellow or blue raid. It was in order to avoid such problems, Apple introduced the function of automatic balance of balance in her devices. Thus, regardless of the lighting level, the white color on the screen will always be perceived as white, thereby increasing contrast and correct color rendering.

Turn on True Tone on iOS devices is easy:

True Tone inclusion in MacOS (on supported Mac models):

As you can see, Retina and True Tone are different concepts that are different in essence. The first term denotes the high clarity of the display, and the second. color rendering and contrast (white balance settings). In other words, you may have a device with a Retina screen, but without support True Tone. Recall that this technology appeared not so long ago, so it is present on relatively new devices. In the following articles, we will consider how the modes “Auto.yard”, True Tone and Night Shift are different.

In our Apple Pro service center, you can order an iPhone display replacement while maintaining True Tone performance.

What is Retina display?

Retina (Rétina). Marketing term Apple, translated from English means “retina”. It implies the following: the density of pixel points on the screen is so high that the human eye is unable to distinguish separate pixels in the picture. At the same time, specific characteristics are not hidden behind the name “Retina”. for example, a certain number of pixels or the exact resolution of the display.

The first smartphone with a Retina display was the iPhone 4. He received a resolution of 960 × 640 pixels, which was more than enough for a 3.5-inch display-after all, one inch there had 326 pixels (PPI, Pixel Per Inch).

By the way, in fact, Apple displays were not developed on the basis of PPI, but on the basis of the Pixel-Per-degree (PPD, pixel) parameter). It better determines the ability of the human eye to distinguish between the details at a certain distance. When creating this indicator, the screen resolution and the viewing angle are taken into account. The PPD of the iPhone 4 was 57.

When the first MacBook Pro with a Retina display was released in 2012, he received a record permission of 2 880 × 1,800 pixels on a 15.4-inch screen at that time. The PPI indicator was even lower than that of the iPhone 4 (220 versus 326), but PPD was higher. 79.

A visual comparison of the IPhone 3GS resolution (regular display) and iPhone 4s (retina-display):

Today, almost all Apple devices have a retina display. This consumer does not say anything about how many pixels per inch (or degree) he will receive. because the Apple Watch screen is very different from the IMAC monitor. But this is not important. after all, the inscription “Retina” means that you do not see the pixel screen, t.e. You will enjoy a quality picture under any circumstances. Do many need more?

What is True Tone Aspley?

Unlike terms like HD, 4K, Retina, etc.P., True Tone has nothing to do with the number of pixels on the screen. Its area of ​​responsibility is the color and contrast. The main task is to make sure that perfectly white remains perfect white, in any external light. And the more “white” there will be a display, the more contrasting it will be.

You noticed that the light has a slightly reddish tint in the morning, and in the middle of the day. yellowish? Not? Logical. after all, our brain specially “filters” shades.

Modern screens well reflect the light, but our brain does not notice this and is still trying to filter something that is not. As a result, our perception of colors on the screen suffers. True Tone compensates this by adding warm shades to the display. The brain is happy to filter the picture. and we get a “real” white color, “like a sheet of A4 paper”.

To activate the True Tone technology, open the settings application, go to the screen and brightness section and set the corresponding switch to the VCL position.

In addition, the function can be turned on from the control point:

We talked in more detail about True Tone technology in this material.

How to turn on/disable True tone?

There are two ways to turn on the function, choose which one you like.

Inclusion through system settings

We go to the IPhone System Settings, select “Screen and Brightness”. “True Tone” and turn on or off the function.

Inclusion from the control point

To do this, just brush the display to call the control point. Find the slider adjusting the brightness and for a short time we clamp it. The adjustment panel with the “True Tone” button will open, activate it.

Why does True Tone not work on iPhone?

Recently, this malfunction has become more and more common. Many owners of Apple smartphones are looking for information how to restore the tone tone. Although the factors of malfunctioning can be individual, most often the reason is unskilled replacement, repairs of the display. The fact is that the information on brightness control is stored in the iPhone screen controller, and it should be synchronized with the data on the device itself.

The iPhone display controller contains data on the model, serial number and smartphone configuration. What happens at the time of installation of a new display unit? The conflict between the data, in connection with which, the screen simply does not integrate into the system. It can issue a standard image, but such a function as True Tone stops working. In this case, it is not important whether the original or copy is installed. To fix the problem, our experts make a new display, after which the technology turns on and operates normally. It is best to provide a native screen (even damaged), but if it is not preserved, there is an opportunity to do with professional means of our service. To completely avoid the “loss” of the True Tone function, it is necessary to replace the glass on the iPhone screen.

The essence of technology

True Tone is a technology that allows your iPhone, iPad or Mac to adjust the image of the display under the environment.

To understand how True Tone works, we will begin to recall a small part of the school curriculum. We all know that light is an electromagnetic radiation that moves in space in the form of waves, and the length of this very wave affects the color that is perceived by our eyes. For example, the wavelength of 450 nm is a blue color, and 650 nm is red.

If we take any object that surrounds us, then it has no color, our subjective perception works exclusively. Just the material from which this or that object is made absorbs light waves of a certain length, the rest of the waves are reflected and perceived by our vision.

And if we take some black item, then it absorbs all the waves, and nothing reflects from it. It is logical to assume that the white sheet of paper reflects everything and does not absorb nothing, so it seems to us white.

When the True Tone function was announced in Apple, Cupertino just gave an example with a white sheet of paper.

If we look at the most ordinary white sheet, then under different lighting its shade will differ. Under an ordinary incandescent lamp, the paper will turn yellow, and have a bluish tint under the daylight lamp.

Of course, the human eye automatically adjusts the perception, and for us that the one that this option seems white. But in fact they differ in a shade depending on the lighting.

How True Tone works on iPhone

So, in Apple we decided to try to imitate the reflected light and configure the screen shade so that in different environments under different lighting the screen of your smartphone, tablet or laptop corresponds to this very environment.

Therefore, if the iPhone sensors capture the warm light of an ordinary light bulb, then the screen begins to turn yellow, as if imitating the behavior of an ordinary white sheet of paper, and vice versa, automatically adjusting the balance of white.

Of course, this does not mean that the shade of your iPhone screen will be 100% coincide with a sheet of paper, since, unlike paper, the display does not reflect the light, but radiates it. That is, the smartphone is trying to imitate the reflected light.

For this, sensors are used, which in new models are part of the Face ID system through which the iPhone receives the information you need.

But different factors, such as our face or other interference, can affect the sensors of the surrounding light and temperature, which can lead to a not very perfect work True Tone.

Sensors in constant mode monitor the color temperature of the surrounding lighting, adjusting the white balance on the display for better perception of the picture to users, so that the difference between the surrounding lighting and the light from the screen is as little as possible.

What is the True Tone display in iPhone?

Apple first introduced the True Tone display with the output of the iPad Pro in 2017. True Tone is a system that adapts the screen of the screen under the surrounding lighting. As you know, the light, which is commonly called white, is not always such. Even the light of the screen that seems white may differ in temperature. Sometimes the display shines blue, and in this case the light is considered cold. If the light gives yellow, then the glow of the screen is warmer.

The screen of devices without True tone is always the same white. If you open a web page on the screen, while in a room lit by LED lamps, the display will really be white. However, if you open the same page on the street on a sunny day, it will seem to you bluish. True Tone technology compensates for this difference and adjusts the glow of the display under the surrounding lighting. White always remains white, regardless of conditions-on the street and indoors, in summer and winter, with LED lamps and in the twilight.
