How to find out which screen by the number of the touchscreen. Find out where and look at all the technical characteristics of the monitor. Touch screen types

The popularity of smartphones and tablets is growing every day. The ever-increasing demand is very simply explained by the advantages of these devices: compactness, weight, savings in energy consumption and battery life. Quite often, tablets are used both at home and at work to view videos, photos, various websites, presentations and other documents. What can we say about smartphones! Most of their owners, having forgotten the gadget at home, already feel "as if without hands."

Everyone knows that smartphones and tablets with a large touch screen are very fragile and often break. Such gadgets require careful handling and proper storage. The most common "sores" are the fall of the device and mechanical damage during daily use.

Could not be an exception and Chinese multimedia devices. They gained their popularity due to their low price.
More recently, in the event of a gadget breakdown, you would simply be advised to throw it away and buy a new one. Previously, compared to today, it was very difficult to choose the right touchscreen for a tablet or smartphone!

Online store GsmServer provides a wide range of touch screens for Chinese smartphones, tablets. We invite you to read this article to find out how to correctly identify and select a spare part (display, touchscreen) specific to your device.

There are different types of displays and touch screens. First you need to determine what part you need.
Today, there is a trend in the production of Chinese tablets and smartphones to use capacitive touch screens, so we will start with them.

You need to start with the simplest - determine the size of the touch screen (display). The first characteristic to be measured is diagonal. You can try to find the parameters on the manufacturer's website or in the instructions. But, if this is not possible, then the usual ruler is used, with the help of which we measure the size of the sensor (display) diagonally. Put a ruler on the screen, measure the distance from the lower left corner to the upper right corner or vice versa.

If the ruler does not have an inch scale and you need to get the result in inches, divide the resulting figure by 2.54 (1 inch = 2.54 cm). This will give you the screen size in the standard measurement system, that is, in inches. After the measurements, the following result was obtained - the screen diagonal is 22.85 cm, which is equal to 9”.
Now determine the outer dimension. Measure the height and width of the sensor (display), while ignore the frame.

So, we got a sensor width of 233 mm and a height of 143 mm. Use the filter on the site and enter there all the data and numbers known to us, namely:
Models with a diagonal of 9”;
Type - capacitive;
Size - 233 * 143 mm.
This is the list of products we will receive

But that's not all! There are quite a few Chinese devices on the market, and in appearance they can be exactly the same, but the filling turns out to be completely different. Therefore, the tablet must be disassembled. There are simply no other options, since there are many factories that create their own versions of devices. Having disassembled the tablet or smartphone, the first thing note, how many contacts (pin) are on the cable. We have counted 50pin. Also, to determine if a touch screen or display is right for you, you need to check the markings - TPC0712.

According to all the above criteria, a product with the code 845478 is suitable for us, namely.
So, you have found the spare part you need on the site. Now carefully study the appearance of the touch screen from the photo, in particular, the appearance of the loop and its location.

Carefully study the appearance of the touch screen.

A completely different situation develops with touch screens of a resistive type.
What is it? A resistive sensor is two films glued together that measure resistance as the touch point moves. One film reacts to the shift of the touch point vertically, and the other horizontally. Having the initial data on the resistance of the films and their resistance at the moment of contact, we can obtain two coordinates: one is “vertical” and the other is “horizontal”. Then the resistance of the films is converted into a digital code, which is calculated by the processor of the device.

Here is the equivalent circuit of a resistive sensor:

It happens that finding a sensor with the desired characteristics is quite difficult. Finding a screen that fits is not a problem, but it has there may be a different location or shape of the conclusions. In such situations we recommend: take a suitable size sensor and call out the leads with a tester. Focus on the equivalent circuit drawn above. Finding the pins corresponding to the two "resistors" will not be a problem, and to determine which of the resistors is horizontal or vertical, you need to measure the resistance of the sensor when you touch it at various points. Carry out the same manipulations with the old sensor.

Now turn on your imagination! You can solder the sensor leads to the corresponding contacts on the board with thin wires, or try to bend the cable.
Of course, doing such "tricks" is quite difficult, but this way you do not have to look for and wait for the delivery of a sensor (display) that would fit perfectly. Yes, you will spend some time on all these procedures, but you will have a working apparatus.

When soldering, do not forget about static electricity!!! You can break the phone by just touching the contact pads on the board with a soldering iron.

Don't forget polarity! The sensor resistors have negative and positive terminals. But this is not a minus / plus, as is commonly understood. The touchscreen works when connected to any polarity. Here we are talking about geometric plus and minus.
Having mixed up the polarities, you will get the following picture: when you touch the icon located in the upper part of the screen, the icon in its lower part will work, or when you press the right button, the left one will work. To eliminate this inconvenience, swap the wiring to the appropriate sensor.

Buying a new sensor it is necessary to clarify its physical characteristics. Screen sizes can vary significantly from each other, but the resistance of all sensors is approximately the same. And this means that it is necessary to measure the "native" sensor as accurately as possible. It is necessary to measure only the width and length of the sensor itself (film), but in no case the housing cover. Measurements can be taken with a regular ruler, an error of +/- 0.5mm is allowed.

Remove all protective films only before assembling the machine. Fingerprints, dust particles and other small things will look unpleasant on the inner surface of the screen. After performing all the above manipulations, calibrate the sensor in the corresponding menu item.

We wish correct work for all your devices, for its part, GsmServer always offers for tablets and smartphones.

Smartphones have become devices that can replace personal computers and laptops. They are equipped with high-performance processors, RAM, graphics accelerator.

A modern phone is an advanced means of communication, it can install not only mobile applications, but also programs that were previously used only on computers. For example, a gadget may well play the role of a navigator, because. has a built-in GPS receiver. With the development of technology, for many users the question arose of how to check the technical characteristics of the device, because a wide range of resource-intensive operations can be performed on the phone. It is on what components a smartphone is equipped that its performance depends.

At the moment, the bulk of the mobile device market is divided between Android and iOS operating systems. The vast majority choose the first option, because. the combination of performance and price is optimal. Next, ways to check the phone for both operating systems will be described in detail.

Why is it important to know the characteristics of the device

In order for the phone to work without freezing, you need a high-performance processor and an optimal amount of RAM. For video calls, you need a camera with sufficient resolution. The choice of device should be based on the needs of the user, for what purposes the device will be used.

An important factor in choosing a device is the architecture of the microprocessor. To date, Google has forced Android application developers to release software only for 64-bit architecture.

It is also necessary to pay attention to the characteristics of the graphics accelerator, it depends on it how high-performance games will work. Games on smartphones have long been supported by the latest graphics technologies and, accordingly, the quality of the image output to the screen of the device is no worse than on personal computers. At the same time, for a high-quality picture, it is necessary to take into account the type of screen, the most advanced technology is AMOLED. But there are other types: TFT LCD, IPS, AMOLED SUPER, etc. This also includes pixel density, color reproduction, refresh rate.

Not all manufacturers of mobile devices indicate the full names of the technical components of the phone on the box and manual. If there is no information about which processor or video chip is installed on the smartphone, you can use third-party software to display complete information, as well as the standard capabilities of the mobile OS. Next, the question of how to check a smartphone will be discussed in detail.

We use standard tools of the Android operating system

You can find out the technical characteristics of the phone using standard tools, for example, the "Settings" menu:

• first you need to go to the "Settings" menu;

Settings

• then scroll the list to the "System" block and select the "About phone" item;
• after that, information about the processor, RAM, firmware of the communication module, wireless transmitter, etc. will be displayed on the main screen;

Those. information

• by going to "General Information" you can find out the IP address, MAC address, charge level, battery status, etc.

general information

Find out the technical characteristics of the iPhone

You can find out the technical characteristics of gadgets from Apple as follows:

• In the first case, it is enough to look at the box, where the model number and brief data will be indicated above the barcode. For a detailed acquaintance, it is enough to drive the name of the model into the search engine and look at the information on one of the technical sites.
• In the second case, you can find out information about the installed components through the official website of the developers. It is enough to rewrite the model number from the packing box and go to a special Apple page where you need to enter data and get complete information about the equipment of the phone, up to the year of manufacture.
• The third way is that you can use the standard operating system tools. You need to go to "Settings", then open "General" and "About device". It will display general information about the machine. For details, in any case, you need to resort to the help of the official website. In the “About Device” item, you need to copy the “Hardware Serial Number” and go to the “Check Service Rights” page and enter the data.

Technical condition

Hello friends! In one of the previous publications, we examined what you should pay attention to when buying it. Perhaps someone does not need to purchase a new device yet, but suddenly it took to determine the parameters of a long-standing and successfully used one.

Today we will look at how to find out the characteristics of the monitor quickly and easily. We will talk not only about methods that allow you to clarify absolutely all technical parameters, but also about those that will help you find out only the most basic of them.

Determine by model

Perhaps the easiest way is to determine the model of your monitor and “dance” from there. I heard the opinion that manufacturers of monitors and other computer hardware are very fond of their products, so they mold the brand and brand wherever possible.

If it was trolling, then very subtle. In fact, there is no question of love or pride for such wonderful products - these data are required to be indicated by international regulations. Mandatory brand and model of the monitor must be present:

• On the packing box;
• On the instruction manual and warranty card;
• On a nameplate affixed to the back of the monitor.

Even if you disposed of the box, and the evil spirit stole the warranty card, the nameplate on the monitors of most users remains intact. You just need to get to it to see the model.

Keep in mind that it can be glued not on the back, but on the bottom, near the ports for connecting the display to the video card.

Optionally, the monitor model can be written on the front panel (with the exception of frameless copies that do not have space for this) or a bright sticker, which is almost, but not always, molded by the manufacturer to attract the attention of a potential buyer.

On the same sticker, the main characteristics of the product are usually indicated.

Having learned the model, it is enough to go to the Internet and find a site containing information on a specific model.

This can be a device manufacturer's website, a text or video review of a specific model or a comparison of several, or an online store that sells monitors and other peripherals - for example, this By the way, I recommend it, I often use it myself.
What if Google doesn't find the product's specifications? That doesn't happen. Google knows everything, I guarantee. And what he does not know, they know Yandex or Bing.

Standard Windows tools

Some monitor parameters can be found using the basic tools of Windows 10, 8 or 7. There are no fundamental differences in the names of menu items, since the changes in these versions have affected the interface more than the OS structure itself.

You can quickly determine the model of your monitor by going to the control panel and selecting the "Devices and Printers" item, where, among others, you will find the monitor model. The brand is usually indicated on the monitor itself - the company logo is centered below the screen.

You can learn a little more, as well as configure some settings, using the ATI Catalyst Control Center utility or the Nvidia Control Panel, depending on the chip installed on your video card.
Additional installation of these programs is usually not required - they are installed on the PC simultaneously with the graphics accelerator drivers. In the relevant sections, you can see the following technical characteristics of the display:

• Current and maximum resolution;
• frame rate;
• Image orientation;
• Port used for connection;
• Color depth and color scheme used;
• Support for digital audio monitor.

Of course, these are not all technical parameters, but sometimes they are quite enough. If you need complete information on a specific device, which may not even be on the manufacturer's website, I recommend moving on to the next method.

Special utilities

There are special utilities that cannot change the parameters of the computer and peripheral devices, but they can collect detailed information on many aspects of work and generate appropriate reports. The most famous of them include:

• Everest;
• AIDA64;
• PC wizard;
• System Explorer;

These are great ways to get to the bottom of your display as a specific device with a specific ID. Other information displayed includes interesting data such as production date and total operating time.

Also here you will find the characteristics of individual modules, which is simply not in the basic Windows tools. The only drawback of such programs is that for some reason none of them determines the type of matrix - there is no such item in the interface at all. Strange, right?

And that's all for today. Share my publications on social networks and - it never hurts. Till tomorrow!

The screen resolution of the phone is set by the manufacturer. Sometimes it does not suit users, for this reason many people want to change it. There is no way to change permissions using the gadget settings. Usually you need to get root rights on your smartphone and install some applications.

However, this does not stop many, they do not want to put up with large uncomfortable icons on the screen. For games, the convenience of using a smartphone, you need to adjust the screen. However, first you need to find out the resolution of the device in order to put the same back if necessary.

How to check the screen resolution on your phone

Screen resolution is the number of pixels in a given area. The higher this indicator, the better and clearer the image will be. On inexpensive models of phones or tablets, as a rule, this indicator is small. Therefore, the resolution needs to be increased.

Finding out this indicator is quite simple, take a screenshot of the screen. Depending on the model, the buttons for performing this function are different, but usually these are “volume” and “lock”. After you take a screenshot, look at the number of dots in the file information.

How to Change Screen Resolution on Android

You can do this with the help of special applications. One of the popular and easy to manage is the LCD Density Modder Pro. However, first you need to get root rights, also make a backup copy. Because if something goes wrong, you have to reset the settings. Download the app and open it.

It is worth noting that the utility is in English, so it may seem inconvenient. Android OS must be at least 2.2, so it will fit most modern devices. The application allows you to save, import settings.

How to change the screen resolution on Android using the file manager

You need to download any explorer in Google Play. You will also need root rights, otherwise nothing will work. After the application is installed, you need to find the System. It should contain a file called "build.prop". Open it with a text editor and change the number of dots on the screen, but remember to match the screen's capabilities.

When buying a smartphone, you need to check it for authenticity. The best option is to go to the bootloader, however, if the key combination is unknown to you, you can use third-party applications that will allow you to determine which processor is installed, what resolution the display has, and other parameters. And it is AIDA64 that can act as one of the options.

In addition, AIDA64 can also be installed if you decide to study the insides of your device in more detail, since the application provides a lot of information. And, most interestingly, all the data in our case completely coincided with reality, which cannot be said about AnTuTu, which determined that a 6-megapixel camera was installed in the test One X, although in reality the device has an 8-megapixel module.

The interface of AIDA64 is simple, convenient and made in material design. The main screen is a list of categories, each of which will tell the user about certain parameters of the smartphone.

For example, if you go to the “System” section, the screen will display information about the smartphone model, manufacturer, serial number, amount of RAM, its free part, and so on.

The "CPU" section shows the processor model, its architecture, cores, frequencies, manufacturing process (40nm in our case!). In turn, the "Display" tab will describe in more detail the GPU, display resolution, its technology, screen sizes, diagonal, very accurate pixel density, OpenGL version, and so on. The "Network" tab contains information about your network connections, including a network mask, gateway, and information about support for Wi-Fi Direct technology. By the way, mobile communication data is also available and described in a fairly detailed form.

Of the interesting, we note the "Sensors" section, which shows information about all sensors, in addition, their work is displayed in real time. This way you can be sure how accurate and correct your sensors are. And the "Temperature" section will show how hot your smartphone is.
But this is still not all sections of AIDA64. If you want to learn more about AIDA64 and your device, be sure to install this application. At least as an alternative to AnTutu and GPU-Z, this is a very good option, and besides, it is constantly updated and brought to mind.
