Replacing glass in an interior door. Replacing touch glasses and screens on cell phones How to change the protective glass on a Samsung phone

Screen mobile phone- This is a very fragile and important component. Damage to this part makes the operation of the smartphone almost impossible, but what should you do if you still receive a defect? You can try to take the initiative into your own hands and tackle the repair procedures yourself. This kind of entrepreneurship can save you a good amount of money. How to change the glass on your phone? There are instructions that will allow you to repair the device yourself at home. We will pay attention to these instructions in this article.

Features of repairing glass of a mobile gadget at home

When falling, most often the touchscreen takes the brunt of the impact. Huge number calls to the service center are associated with precisely this type of breakdown.

Important! This prospect is not very encouraging, since some cases of replacement in workshops will cost you half the cost of the mobile phone itself. This situation is caused by the fact that many device models use OGS screens.

In order to divide the display into a touchscreen and a matrix, acquire the most simple tools(a vacuum suction cup, a Phillips screwdriver, a sharp knife and a thin flat object) will not be enough. All replacements usually occur in the following order:

Disassembling the device.
Removing the damaged module from the housing.
Strong fixation and heating of the display using special equipment.
Separation of the matrix from the touchscreen using a special nylon thread.
Cleaning the matrix from technical glue.
Placing the component on a special stencil for subsequent application of photopolymer colorless glue.
Placing the sensor in a stencil to remove excess glue between layers.
Irradiation with ultraviolet rays for rapid hardening of the glue.
Returning the module to the case and assembling the device in the reverse order.

Important! As you may have noticed, without special equipment you won’t be able to do the repairs yourself. Unfortunately for most users, OGS screens are installed on almost everything modern smartphones and all independent attempts to carry out a replacement are relevant only in those cases if you are interested in gaining experience and do not at all mind breaking the device.

How to change safety glass on the phone? If you are still filled with courage and desire to return the device to stable operation, then there is one way for you.

We replace OGS glass at home

Disassembly should only be undertaken by users who have some experience in this area. It will be very difficult for a beginner to avoid new damage. To carry out disassembly, you need to use the following tools and available materials:

A small set of Phillips and Torx screwdrivers for disassembling the case of a mobile phone.
Plastic spatula, unwanted debit card or guitar pick.
The most common hair dryer, capable of heating the screen to about 80 degrees Celsius.
Thin nylon thread or guitar string. These tools will be needed to divide the module into its component parts.
Work or medical rubber gloves.
Rubber suction cup with ring.
Some kind of perforated metal sheet and about a dozen bolts and nuts. The length of the bolts should be about 2-3 cm.
A special glue that hardens when exposed to UV (ultraviolet) radiation.
Ultraviolet lamp, pure alcohol or glass cleaner and computer wipes.

Important! Shaped screwdrivers, technical picks and plastic spatulas with suction cups are often supplied with a new touchscreen. It is best to use the above replacement tools.

Replacing glass on your phone yourself looks something like this:

First you need to disassemble the device body. The task is simplified if the mobile phone is equipped with a removable cover and battery. After disassembling the case, take a screwdriver and unscrew all the screws that secure the elements to the case. On YouTube you can find hundreds detailed instructions for carrying out this procedure.
Now you need to take on the display module itself. We take a hairdryer and warm up the smartphone around the perimeter. We “grab” the module with a suction cup and pull it slightly towards ourselves, not forgetting to warm up the entire structure with a hairdryer. Try not to damage the cables when removing the part.
Now we need to prepare for delamination of the extracted module. Simply place it on a pre-prepared metal plane with holes and screw bolts around the perimeter of the module so that it does not move.
Let's move on to the bundle itself. We take the same hair dryer and thoroughly warm up the matrix to about 70-90 degrees Celsius. Now we take a nylon thread or a guitar string in our hands, grab it by the edge, and continuing to warm it up, we “cut” the components.
If everything worked out for you, then clean the matrix from the remnants of old glue using alcohol and napkins. All this must be done very carefully to avoid damaging the screen.

Important! You should wear gloves to avoid leaving any greasy marks. If the layer of glue is removed without problems, then wipe the component with alcohol one more time.

We coat the matrix with new glue, in accordance with its new touchscreen. Now we press lightly on the structure and remove the glue protruding from the sides.
You need to irradiate the glue under a UV lamp for about 30 minutes.
We begin installing the module if there are no traces of the old glue left. We place the module on the cable and lubricate the body around the entire perimeter with glue.
We glue the whole thing onto the body, wait for it to dry and assemble the gadget in reverse order.

Important! Don't forget to check the functionality of the device.

How to replace the protective glass on a phone if it is not OGS technology?

Changing the glass on a smartphone

If your device uses a screen with an air gap, then you can safely take on the replacement. This is exactly the case when you will be able to save 100%. But this method also requires a certain base of technical knowledge and the ability to use a soldering iron. You will need all the same tools that were used in the previous method, and you need to follow these instructions:

We disassemble the phone in the same way as in the previous method.
We remove the screen using a hairdryer, place the suction cup on the touchscreen and remove it.
Now you need to get rid of the damaged part by sending the obsolete component for scrap. After this, we clean all workspaces from glue or tape.
We install a new component. Before installation, remove the film from the matrix module. Thin strips of double-sided tape or B-7000 glue are applied along the perimeter of the structure. Place the sensor in its rightful place and press it until dry. Don't forget to remove any spilled drops.
If soldering was used to attach the module, then take a soldering iron in your hands and fix the part around the perimeter using solder.
We reassemble the entire phone in reverse order and check its functionality.

- a fragile thing, and very important. You can say in the style of “Captain Obvious” that if it is damaged, the phone becomes impossible to use, but people are more interested in something else: is it possible to replace the screen on the phone yourself? Considering that in service center for this procedure they usually charge at least 1000 hryvnia (even for a budget device) - the issue of saving becomes acute. We’ll try to find out the intricacies of the replacement below.

Any material should begin to be processed with theory. If you came here from a search engine by entering the query “how to replace the screen on your phone with your own hands,” new knowledge definitely won’t hurt. If the purpose of reading the material is to obtain some new information, in addition to what was learned earlier, this subheading may not be studied.

The touch display of a modern smartphone is a complex device consisting of several functional elements. The main ones are the matrix and the touchscreen; there may also be frames, keys, backlight elements and, of course, cables, in quantities from 1 to 3-4 pieces.

Matrix- a liquid crystal or LED panel on which an array of pixels is placed that forms an image. The front side is covered with a very thin layer of glass, and the rear side has a stainless steel case. It is also equipped with a cable for connecting to the board, and may have other small elements on it.

Touchscreen (sensor)- transparent touchpad made of glass, covering the entire front part of the smartphone. It is a thin sheet of glass (less commonly, plastic), on which a transparent layer of conductive material is applied on the inside, and an oleophobic coating on the outside (optional).

In some cases (lately - more and more often) the touchscreen and the smartphone matrix represent one whole. They are supplied as a single module and are replaced together. This design is called OGS.

OGS screen(from the English one glass solution - a solution with one glass) is a type of smartphone screen in which the sensor and matrix are connected together in the form of a “sandwich”. Distinctive feature OGS matrices are a very thin layer of coating that protects the pixels, since the main element of their protection is the sensor.

Whether it is possible to replace the phone screen yourself depends on the reader’s ability to work with tools and the type of matrix. Some smartphones can be repaired very well at home, but not even every repair shop technician can handle others. We will discuss below which screens can be replaced even without experience, and which are best left to a specialist.

How to replace the glass on your phone screen yourself

The touchscreen of a smartphone is the first to take a hit when dropped, so it suffers more often than the matrix. Therefore, the number of calls to the service center caused by glass damage is greater than the number of cases of a broken matrix. However, this is not always reassuring, since replacing one touchscreen is sometimes more expensive than replacing the entire module. This situation is caused precisely by the use of OGS screens.

To divide the OGS display into a touchscreen and a matrix, to replace a damaged sensor, you will not be able to get by with simple tools (suction cup, screwdrivers, knife, pick). Replacing the sensor on the OGS screen under SC conditions occurs approximately in this order:

Disassembling the phone.
Removing the module from the smartphone case.
Fixing and warming up the screen on a special stand.
Separation of the matrix and touchscreen with a special thin nylon thread.
Cleaning the matrix from glue.
Placing the matrix in a special stencil, applying photopolymer transparent glue.
Installation in stencil touch screen, removing excess glue between it and the matrix.
Irradiation of gluing with a UV lamp to polymerize the glue.
Installing the module into the housing.
Assembling a smartphone.

As you can see, without special equipment (a heating stand, stencils, transparent photopolymer and a UV lamp), you will not be able to replace the glass on the OGS screen yourself. Unfortunately, such screens are now installed in most Samsung smartphones, LG, Sony, Xiaomi, Meizu and, in general, almost all devices more expensive than 3000 UAH. Apple has been using OGS displays since the iPhone 4S. Therefore, independent attempts to change the sensor (without a matrix) on these devices are justified only if you have a lot of time, a desire to learn, and if you don’t mind the phone.

In the video you can see how an experienced person changes the sensor on an OGS display using a minimum of tools:

For the desperate: how to replace the glass on an OGS screen yourself

If your budget is limited and you don’t want to overpay again for a damaged matrix - this section Worth reading for general information only. It’s better to immediately purchase an assembled OGS screen module and not take risks. The editors are not responsible for broken screens, torn cables and other consequences of unsuccessful experiments.

Owners of some flagship smartphones(HTC One M series, Samsung Galaxy, released after 2015, and not only) independent intervention is contraindicated. Disassemble them without experience, without damaging the body parts, impossible.

For disassembly you will need the following tools and supplies:

Set of shaped screwdrivers(cross and star), for disassembling a smartphone.
Plastic card or mediator, spatula.
Hairdryer, capable of heating the screen to a temperature of 70-90 degrees (an ordinary one for hair is suitable).
Thin nylon thread or string to separate the module.
Gloves(workers and medical).
Rubber suction cup with ring.
Metal flat surface with holes(perforated sheet).
6-8 bolts with nuts(diameter depends on the diameter of the holes in the sheet, length - 2-3 cm).
Photopolymer glue, hardening under the influence of UV radiation.
Transparent atmospheric curing adhesive(eg B-7000).
UV lamp(you can use a regular carrier with an E27 UV lamp, or you can take a manicure UV camera for nail extensions).
Windshield cleaner, alcohol, wipes.

Screwdrivers, picks, paddles and a suction cup are often included with the new touchscreen as a bonus. You can use them for replacement.

To replace the glass on a phone with an OGS screen yourself, the procedure is as follows.

Modern touch phones and tablets have a high-quality screen with a large diagonal. They are comfortable to surf the Internet, play games, run various applications, watch photos and videos, and read books. All this can be done by a display module, which is at the same time glass, display and touchscreen. But this element is the most vulnerable part of the phone. If there is mechanical damage or a fall, it may crack like a cobweb or several unpleasant cracks may appear. Previously, in such cases, it was necessary to change the display module, the cost of which is usually half the cost of the phone itself. Now a similar problem can be solved by replacing only the glass.

What is a glass cut?

Separation is the process of separating the display from the glass when only the glass needs to be replaced. All modern smartphones are produced with glued glass and display. This allows the thickness of the display module to be reduced. Navigation becomes more comfortable, and the image is clear and realistic. Also in almost all modern models phones there is no air gap between these two elements, which is filled with special OCA glue, this gives the device even greater aesthetics. Separation allows you to divide the display module into individual components and replace damaged glass.

Depending on the phone model, it allows you to save on average about 1,000-15,000 rubles on repair costs. We can replace the glass on any phone in which the entire module needs to be replaced. The cost of such a service is affordable to everyone and will allow you to return the gadget to working condition much cheaper.

When do you need glass replacement on your phone?

1. The touchscreen broke, cracks, chips appeared on it, deep scratches and at the same time the screen shows. This often happens when the phone falls or other mechanical damage occurs.

2. The sensitivity of the touchscreen has decreased or completely disappeared, and blind spots have appeared. It may occur due to an impact, liquid getting inside the phone, or a manufacturing defect.

3. The protective glass is covered with a network of cracks, but the touchscreen works. U popular phones Double glass is often used.

For any of these problems, contact our service center and we will quickly replace the glass on your phone or tablet. The professionalism of our craftsmen and affordable prices will appeal to all clients.

How the glass is cut

Cutting glass is a complex procedure that is performed only by professionals using special technology. The work uses specialized equipment and consumables. Glass replacement in our service center takes place in several stages:

We disassemble the phone or tablet and carefully remove the display.

We layer it using a separator machine or use a special machine that cools the display to -150C

- Using special liquids, we remove the remnants of the old OCA glue, which connected the elements of the display module and removed the air space between the module and the glass.

In a dust-free room, we apply new OCA film and install new glass.

We laminate, pump out the air in a special laminator under a pressure of 5 atmospheres and remove air bubbles.

We collect the phone.

After completing the entire glass replacement procedure, your display is back in working order and free of cracks, and you can use it comfortably again. The cost of such a repair will be several times lower than installing a new display, and in some cases, it will be the only option to restore the phone.
