Your iPod, iPhone and tabletare commonly known to have three key components: a glass panel, digitizer (aka touch screen) and LCD. What are the differences? Let’s clearly define these layers:

Digitizer –The digitizer is located just under the glass screen. It is the electrical force that senses and responds to touch. When you tap your fingertip or swipe it across the screen, the mere touch acts as data input to the device’s center. If your device fails to respond to touch, it’s time for a new digitizer. The digitizer is an electrical mechanism that is fused with the glass screen; so if you need to replace the digitizer, you’ll have to replace the glass, too, and vice versa. UEGoffers a Front Glass (Digitizer Touch Screen) Repair Service on tablets.

Touch Screen –  The term touch screen is interchangeable with the term digitizer. You’ll often see the combined terms Digitizer Touch Screen offered as a repair service.

LCD – LCD is an acronym for liquid crystal display. The LCD is the visual component underneath the glass that displays the image on the screen. UEGoffers LCD repairs on tablets, iPhonesand iPods.

The easiest repair for mobile phones to complete is the LCD assembly replacement. This repair takes less than an hour and requires the least amount of technical ability. For some devices the LCD assembly can be replaced simply by removing a few screws and cables. Also, as the assembly includes the glass, touch screen and the LCD, you can be confident it will fix all common screen issues.

For iPad and other tablets, if the screen parts aren"t fused, then you can do a glass touch digitizer only replacement. Otherwise, the full assembly is the easiest repair. Either way, it usually takes 1-2 hours.

While it can be significantly cheaper repair, If the screen parts are fused, the screens must be heated to loosen the adhesive between the screen and LCD and you need special equipment. This includes all iPhone and most other mobile phones and some iPads or tablets. A heat gun or hair dryer can be used for this. The screen is then gently and very slowly pried apart from LCD. DIYers need to use care to insure the LCD is not damaged in the process.

Tip: Transferring the home button on an iPhone or an iPad can be the most tricky part. It takes a little patience and heat. You can purchase screens that have the home button pre-installed (along with other small parts) and this is the easiest of all repair. This can take 15-30 minutes. However, Touch ID function only works with the original home button so you have to transfer if you want to retain it. Note: some of the iPads don"t have a screen replacement option that includes the home button like the iPad Pro and newer iPad Mini. iPad 1st Gen to 9th Gen screens, have a home button pre-installed option.

As an official phone repair provider who has been in the business for almost a decade, one unique question people ask when they visit our service centres to replace their phone screen is: "what"s the difference between original and copy phone screen?"

Well, the answer is, there are many differences between these two screens, which is mostly in their quality. And while “copy” phone screens are somewhat cheaper than the originals, it doesn’t justify the difference in quality. So, before you regret replacing your phone screen with a forbidden part, the tips below will tell you the critical differences between original and copy phone screens.

Generally, phone screens manufactured from your brand"s factory are the original ones while ‘Copy’screens are the ones designed and produced by third-party manufacturers and factories that are not related to your brand.

Many people usually like to go for copy screens because of their cheaper price. However, the "real" differences between original and copy screens lie in their quality, and here’s what you need to know about them.

One of the principal issues with "copied" phone screens and why it differs from the originals is touch and digitizer problems. And that"s a big problem since you"re going to control the device with the touchscreen anyway.

As far as we could remember, phone manufacturers build the touch panel/digitizer with the LCD itself, while the copied screen manufacturer build it separately on the surface glass. Hence, there"s a difference in touch sensitivity. Additionally, copied phone screens usually drop the high touch sampling rate, meaning your screen may not respond to your touches faster.

Here"s also another major issue with the digitizer on copied phone screens. When you crack a copied screen accidentally, the touchscreen stops working, stopping you from accessing the device until you fix it again. Meanwhile, the touch on the original phone screen works perfectly, even after undergoing severe cracking.

Besides having touch problems, most copy phone screens usually have poor display properties. That means you get lower brightness, colour accuracy, sharpness, contrast, etc. And when the display isn"t great, watching movies and viewing other content becomes boring.

For instance, if the original screen is supposed to have 480 nits of brightness, but the copy screen has just 200 nits, the screen becomes unusable under bright lights. Moreso, copied phone screen seems to have more blue light, which, in return, affect your sight and disrupts your sleep at night.

Among others, copied phone screens drop higher refresh rates, and that"s a bummer since most phones come with at least 90Hz refresh rate screens. What that means is the copied screen won’t feel smooth as it’s supposed to be.

It"s not all about the display quality. A copy phone screen may also affect other parts of the phone system if its specifications don"t tally with the original one. In such a case, it could drain your battery at an alarming rate, or at worse, damage your backlight.

If you happen to have a phone with an in-display fingerprint sensor, then replacing its screen with a copied one is not an option – it’s going to mess with your fingerprint accuracy.

We know copied phone screens for their poor quality, and it also extends to the fingerprint sensor. Hence, it takes a longer time to unlock your device. And in other cases, the security of the sensor is not accurate. We"ve seen situations where phones get unlocked with many unregistered fingers after replacing the screen with a copied one.

If you care about your phone"s security and you don"t want a sluggish fingerprint sensor, then we recommend you only go for the original phone screen replacement.

That brings us to the last difference we’re going to mention between copied and original phone screens. They manufacture copied phone screens with poor glass materials. Hence, they break quicker than the originals. And when they do, you’ll be left with only one option: to replace the screen again.

The major reason for choosing the official service centre over third-party/local repair shops summarizes what we"ve said earlier. The official service centre is the reliable place to get original phone screen replacement parts.

Why? As of today, smartphone phone manufacturers/brands release genuine spare parts only to the official service centres and affiliated repair centres. That means third party repair shops get their spare parts somewhere else: usually third-party factories/companies not related to your phones brand.

Besides offering you the original screen spare parts, the official service centres also have other advantages. These include certified and well-experienced technicians to fix the screen, the use of modern tools that won"t damage your phone further, and most importantly, a reliable warranty. Local repair shops usually don"t offer these features; most especially a reliable warranty, which means you"re on your own if the replaced screen gets faulty afterwards.

As far as choosing the official service centre is concerned for genuine screen replacement, then you shouldn"t shy away from Carlcare Service if you own a TECNO, Infinix, or itel phone with a cracked screen.

We"re the official service center for these three brands to cater for your mobile repair needs. And for screen replacement, Carlcare delivers excellently. Our brand-trained technicians replace your cracked screen with genuine OEM parts at affordable rates.

We understand you have a busy schedule; and yes, we"ll replace your screen in the shortest possible time. Start by checking how much it cost to fix your cracked phone screen, then you can book an online reservation service with us to reduce your waiting time and also become a VIP customer.

We have all heard of an LCD and touchscreen, some people do not know the difference, and some do not even know there is a difference, but what exactly is the difference? Many of us have had to deal with a broken touchscreen or LCD at one time or another, especially with smartphones. But how well do you know this device? You should know it pretty well since we use them everyday in our phones, laptops, and even radios!

A radio touchscreen is defined as "a display device which allows the user to interact with a computer by touching areas on the screen". In a radio, the touch screen or digitizer is the input portion of the radio. This thin piece of resistive or capacitive electrically charged glass is as thin as 1.1 mm. Using your finger allows for haptic responses to control the radio and some vehicle functions. A ribbon cable allows for integration into the main circuit board that powers the LCD, touch screen and any buttons built into the radio.

When the touchscreen is broken, you will still see what is on the screen, the screen should operate as normal. Like when you break your phone screen and can still operate the device. While it’s design may seem delicate and fragile, they are made to withstand the constant vibrations of daily driving. Any force greater than a finger tap is more likely to cause damage in the form of a spider web crack. Other foreign objects such as car keys, 2x4s, and the occasional matchbox race car can dent or completely shatter the touchscreen; even the LCD!

The Liquid Crystal Display (LCD) is the output portion of the radio that displays all radio functions and features. An LCD screen is what displays the image from inside of the device. Without the LCD, the radio brain or module cannot be used to its full potential. Today’s car and truck radios act as infotainment hubs providing both in-vehicle entertainment and live information.

When the LCD is broken and/or damaged, you may still be able to use the touchscreen depending on how bad the damage is. When broken, the panel will have dark blobs or a viscous substance and most likely will have a spider web type crack. While the touchscreen seems to act as a protective barrier, any defect can cause secondary damage to the LCD deeming both pieces scrap. Isolated LCD damage with no damage to the touch screen is possible and has been witnessed by our techs; the cause of which is due to some dropping or the impact from a car wreck. The LCD has a thin ribbon cable that connects into a circuit board that powers the LCD, touchscreen and any buttons built into the radio.

My T-Mobile Revvlry screen is broken & i want to fix it, but i am confused on which part of the screen module do i need to fix it. Do i need the Front Glass Only or the Touch Screen or the LCD Display or the LCD + Touch Combo?

The T-Mobile Revvlry screen module is known to have three key components: Glass Panel, Digitizer & Display. To know the differences between different type of parts available for T-Mobile Revvlry, we first need to know what is the function of each of these 3 components of the screen module.

* The Glass Panel or The Front Glass (Top Layer) - This is the top glass layer in the front, which you can touch and feel. Typically less than one millimeter thick, the glass panel does not have a functionality and mostly serves as a protective layer to the screen module.

* The Digitizer (Middle Layer) - A film like component, pasted just below the front glass. When you tap your fingertip or swipe it across the screen, the digitizer senses it and sends data to the phone processor. The digitizer pasted to the front glass together is called as a "Touch Screen".

* The Display or The LCD (Bottom Layer) - The bottom layer which produces the image. The display is the visual component underneath the glass that displays the image on the screen.

Front Glass Only:You need Front Glass when only the front glass is broken / cracked. Means When your phone is working perfectly fine and you can see the display clearly with no black spots & the touch is working fine for all portion of your screen, then you can just buy the front glass and get it replaced in your phone.

Replacing the front glass of a screen module is a very technical procedure and requires lots of experience and machinery. If you don"t know what you need, then better look for other product type.

Touch Screen Digitizer:You need to replace Touch Screen Digitizer for your T-Mobile Revvlry when the phone is working fine, but the phone stops responding to touch. This can happen when you broke the front panel of your phone and it together damaged the digitizer also. If the display your phone is working fine and there is no black spot on your screen, then replacing the Touch Screen is the best alternative.

Again, replacing the touch screen of T-Mobile Revvlry screen module requires technical know how. This procedure also needs some machinery to perform the procedure as the touch is closely pasted on top of the display.

LCD Display:In rare cases the T-Mobile Revvlry display stop functioning properly. This can be due to internal malfunction, water logging, manufacturing defect, etc. In this case, you can replace the LCD Display from the screen module.

Replacing LCD from the screen module will again require technical know how & set of machinery, as you again need to remove the pasted touch digitizer from the LCD display.

LCD with Touch Combo (Folder):This is the complete screen module, means LCD with Touch for T-Mobile Revvlry contains all components of the screen module and is ready for installation in your phone. You can use this part if the screen is broken / cracked or the display stops working.

Replacing Combo (folder) in your T-Mobile Revvlry is a much easier task and can be easily performed by a little technical know how or using some YouTube videos.

This sections lists some of the frequently asked questions about T-Mobile Revvlry. Mostly related to spare parts and accessories for the handset. If interested in knowing more about the same, just click on the question to read detailed answer.

A touch screen display is usually made with three main parts. The protective glass sheet, the digitizer sheet, and the LCD. The digitizer is a thin transparent sheet that is adhered to the protective glass sheet with a transparent conductive adhesive. The digitizer is the only part of the display assembly that is responsible for sensing touch. Since the human touch is conductive it allows the screen to sense the location you touch. The LCD is only responsible for displaying the image on the screen. If the screen is not responding to touch then usually the digitizer is damaged or faulty. Usually a damaged or cracked LCD will display a distorted image or no image at all. So if the phone displays a good image but does not respond to touch then you may have the option of only replacing the digitizer. It"s not as easy of a repair as replacing the whole display but is cheaper. A new digitizer part already has the digitizer sheet adhered to a protective sheet of glass. If a person can remove the faulty digitizer from the phone without damaging the LCD then it is surely more cost effective repair. Some displays have the digitizer fused to the LCD which makes it hard not to damage the LCD if trying to remove the digitizer. If that is the case with your phone"s display it is a lot easier to just replace the whole display. Hope this information is helpful.

LCD (liquid crystal display) is the technology used for displays in notebook and other automated industry computers. It is also used in screens for mobile devices, such as laptops, tablets, and smartphones.

Like light-emitting diode (LED) and gas-plasma technologies, LCDs allow displays to be much thinner than cathode ray tube (CRT) technology. LCDs consume much less power than LED and gas-display displays because they work on the principle of blocking light rather than emitting it.

Each LCD touch screen monitor contains a matrix of pixels that display the image on the screen. Early LCDs screen had passive-matrix screens, which controlled individual pixels by sending a charge to their row and column. Since a limited number of electrical charges could be sent each second, passive-matrix screens were known for appearing blurry when images moved quickly on the screen.

Modern LCDs display typically use active-matrix technology, which contains thin film transistors, or TFTs touch screen. These transistors include capacitors that enable individual pixels to "actively" retain their charge. Therefore, the active-matrix LCDs touch panel are more efficient and appear more responsive than passive-matrix displays.

The backlight in liquid crystal display provides an even light source behind the LCD screen. This light is polarized, meaning only half of the light shines through to the liquid crystal layer.

The touchscreen panel a display device that senses physical touch by a person’s hands or fingers, or by a device such as a stylus, and then performs actions based on the location of the touch as well as the number of touches.

Touch screen glass can be quite useful as an alternative to a mouse or keyboard for navigating a graphical user interface. Touch screens are used on a variety of devices such as computer and laptop displays, smartphones, tablets, cash registers, and information kiosks.

A touch-screen digitizer is one piece in a multilayered "sandwich." In modern devices, the screen that produces the images is found at the bottom layer; the digitizer is a transparent sheet that occupies a middle layer on top of the screen, and a thin sheet of hard, protective glass forms the top layer.

Touching the screen triggers touch sensors immediately under your fingertip; a specialized electronic circuit receives signals from these sensors and converts them into a specific location on the screen as X and Y coordinates. The circuit sends the location to software that interprets the touch and location according to the app you"re using.

For example, when you dial a phone number, your fingers touch the numbers on a virtual keypad on the phone"s screen. The software compares the locations touched against the keypad and generates a phone number one digit at a time.

Touch Screen Glass– The bottom layer is the ITO glass, typically thickness is between 1 and 3 millimetre. If you drop your device, the cracked glass ends up resembling an elaborate spiderweb.

Digitizer – The digitizer is located above the glass screen. It is the electrical force that senses and responds to touch. When you tap your fingertip or swipe it across the screen, the mere touch acts as data input to the device’s center. If your device fails to respond to touch, it’s time for a new digitizer.

The touch screen digitizer is an electrical mechanism that is fused with the glass screen; so if you need to replace the digitizer, you’ll have to replace the glass, too, and vice versa.

Touch Screen Panel- Touchscreen is the thin transparent layer of plastic, which reads the signal from the touch and transports it to the processing unit. It is the part that you can touch without disassembling the device.

LCD – LCD display is an acronym for liquid crystal display. The LCD is the visual component underneath the glass that displays the image on the screen. You can not get to the LCD without taking the device apart first.

1). Quality Control: Every LCD tested with special instruments or main boards before delivery to ensure working. Both Original and High quality OEM products available.

Some of the assembled screen combos work perfectly during quality inspection, however, after installation/being used for a certain period of time, the assemblies begin to separate from the frame, which affects customer satisfaction.

There are a few differences between Genuine OEM parts and high copy/OEM assembled parts. Although high copy products use OEM parts one as their mold, there are still possibilities that the OEM and high copy parts aren’t equal in terms of materials being used or manufacturing techniques. Because of these differences, high copy parts can potentially cause deformation of the front frame; which will cause other potential problems such as preventing screen assemblies from being able to be installed, gaps between the frame and the assembly or the screen assembly separating from the frame.

Let’s take the Nokia Lumia 520 OEM assembled touch screen assemblies for example. The digitizer and front frame of these assemblies are OEM parts, but the OEM factories use liquid adhesive applied by an adhesive dispenser instead of average 3M adhesive, which third party factories commonly use. There aren"t any visible or functional differences in the two assemblies, but after installation you will find small gaps between the OEM assembled assemblies and the front frame. After a period of use, the assemblies tend to separate from the frame.

These phones are the same model but different versions, and though these versions look the same in appearance there may be slight differences in some of the inner components, especially in the screen and the front frame. If you don"t know the parts compatibility in advance, you’re likely to get the wrong assembly.

When ETS tests any of the following parts including digitizers with front frames, digitizer assemblies with front frames or digitizers and LCD screen assemblies with front frames, the requirements are as follows:

①For assembly combos we buy directly from the factories, the adhesive applied and materials used for these assemblies are tested in order to avoid any issues.

If you need to repair your phone screen you may have been looking into different types of screen replacements. You’ve probably heard of the acronyms LCD and OLED in TVs before, but what are the differences between LCD and OLED screens and what will be best for your phone?

LCD or Liquid Crystal Display has been the standard for computer, tablet, and phone screens for the past decade. These screens offer great brightness, high definition, and are becoming relatively inexpensive. We tend to see LCD screens on the less expensive cell phone models, today. LCD screens can have great HD quality and have good performance in direct sunlight but tend to be more inefficient when it comes to power consumption compared to an OLED screen.

Over the past few years, many companies have been switching to newer screen technology: OLED displays. OLED, which stands for organic light-emitting diode, is being used on all of the latest flagship devices. They tout amazing contrast of color, they’re lighter and flexible and tend to be more efficient than LCDs. OLED technology is being used for curved edge phones like theGalaxy S10+and theGalaxy S20, S20+, and S20 Ultra 5G. OLEDs have also been used in folding smartphone displays like theSamsung Galaxy Fold, the newMotorola razrsmart flip phone, and theSamsung Galaxy Z Flip.

OLED displays are being used by Apple in their iPhone 11 Pro Max, 11 Pro, XS Max, XS, and X. iPhone X flagship series and newer will come with OLED. Both flagship Samsung Galaxy S and Note Series have OLED displays as the standard on all recent devices including the Samsung Galaxy S10 and Note 10 series, S9+, S9, Note 9, S8, S8+, Note 8, and so on. These phones also all have OLED displays: LG V40, LG V30, Huawei P30 Pro, Huawei Mate 20 Pro, OnePlus 6T, and the Motorola Moto Z2 Force Edition.

The iPhone 11 and the XR still use LCD displays as well as all other iPhones that came before the X series including the iPhone 8, iPhone 8 Plus, iPhone 7, iPhone 7 Plus, iPhone 6s, and so on. Basically, any iPhone with a Home Button will have a LCD screen on it. The LG G7 ThinQ, LG G6, Moto E5, and Moto E6 all have LCD displays as well.

When getting your device repaired, it is a good idea to use the display type that was originally installed on your phone. For example, if you have the iPhone X, which comes with an OLED display, ideally, you will want to get an OLED replacement. This will keep your phone running as efficiently as possible. If you need a more economical solution it is sometimes possible to get an LCD replacement, but keep in mind that they can drain your battery faster and may not have the same color contrast and may not be optimized for your phone.

One of the easiest ways to determine which display type you have is to go to a true black screen – you can search for this on Google Images. If your display type is LCD your pixels will still be displaying a dark gray light. If you have an OLED display the screen will be totally black. It is easier to tell when this experiment is performed in a dark room. You can also searchGSMArenafor your phone and then view its display type.
