When you drop your device, you may immediately pick it up and try to turn it on to see what happened. Sometimes, the screen will be completely cracked, but there’s still a display. Other times, the screen is cracked and there is no display. A few different things happen when an iPad or iPhone drops. Understanding what happens to the screen can help you know what type of repair you need.

When you drop your iPad or iPhone and the screen doesn’t come on (there is no display) or the display is distorted, it’s likely the LCD screen is broken. This screen has everything to do with seeing what you love about your device. Videos, games, email, and everything else depends on your LCD screen.

Sometimes, you may be able to see the screen, but when you touch it to do something, it won’t react to your touch. This is usually because the digitizer is damaged. Many times, this happens even when you can’t see a crack on your device. This is why many people don’t think they need a screen replacement, and actually, in some cases they still don’t need it. Other components may be damaged that cause the touch not to work, but when those are all working okay, it’s the screen.

There are some cases in which both the LCD and digitizer need to be replaced. If there’s no display or a distorted one AND there’s no touch response, the LCD and digitizer need to be replaced. This is usually what people need when they turn to us with a shattered iPad or iPhone.

If you still don’t know if you should have a LCD or digitizer repair, contact our certified technicians. They can look at your device for free to provide you a repair quote. You can trust our technicians to give you the truth, so you can save money when you may not need both screens replaced. If you do, you can be sure that you’ll receive a quality repair with quality parts.

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.

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.

Most of the time people don’t know the difference between a touchscreen and a LCD screen. When there are dark black blobs on your screen, it’s not because the display screen is damaged, it is the caused due to the damage in the LCD of your mobile phone whereas when there are cracks on your screen its mainly due to the damaged caused to your touchscreen and as compared to an LCD screen it is easier to fix as you only need to replace the display screen of you mobile phone.

An LCD is the part of a phone that displays the image we see on screen. It is the layer which produces and displays the image, therefore if the LCD is damaged you can still use the touchscreen although the panel would have either the aforementioned dark black blobs or the spider web type dark cracks on the display or both it would still function normally. To repair the LCD, a technician would have to pull apart the phone part by part to reach the LCD and assess the damage done which is not required for a touch screen. LCD, which is a liquid crystal display, is widely used in mobile phones as it uses low power and produces good quality images.

The images which are displayed in a LCD are produced through small elements which are called pixels. Pixel is a word everybody is familiar with but what exactly is a pixel? Pixel is made up of a layer of molecules lined up between two transparent electrodes and polarizing filters. There are several types of LCDs, reflective, transmissive and transflective, each has a specific function. A transmissive LCD can produce a clear and good quality image in low light while Reflective screen can produce a very good image in bright light. The transflective screen as the name indicates can produce a good quality image in both conditions, hence it is a mixture of both transmissive and reflective LCD.

Touchscreen is now a part of almost every digital gadget in the 21st century. From mobile phones and laptops to TVs and switch boards, it is now used almost everywhere your eyes fall on. But what exactly is a touchscreen? A touchscreen is basically a device which allows us to directly interact by using our fingers or a stylus. The stylus is a special kind of pen whose tip is covered with a unique coating which allows it to directly interact with the computer. We can use one finger or multiple gestures to interact with a touchscreen device. It doesn’t require a mouse or any alternative device such as a keyboard for navigation. A touchscreen can use several methods to sense our finger, it can use a grid which consists of infrared beams or it can use touch sensitive units to sense our gestures.

With touchscreen, there are several gestures that we can make which would be quite tiresome if we use a mouse or a keyboard like when we double tap the screen while using gallery or while reading a pdf file the screen tends to zoom in and when we double tap again it zooms out similarly we can easily drag different icons and swipe to scroll upwards, downwards even sideways. A touch screen is also referred to as an input device as it takes input directly from the user. The computers require a mouse which makes them hard to use but touchscreen is very simple to use as you are directly interacting with the icons, it is also cost efficient to manufacture touchscreen as it does not require buttons for each icon.

In conclusion it can be said that LCD and Touch Screen have very different functions which makes them different from each other. One deals with production of images and the other deals with receiving the input from the user directly. Although they are different, they are equally important for a digital device.

One of the most common misconceptions we see in the iPhone repair business is the true meaning and understanding of the definition of Non-Original LCD Screens and Original (OEM) LCD Screens.

Culture Differences – Most LCD screens are manufactured or reclaimed to be refurbished in the Asian market. Right out of the gate, there is a barrier of culture and language barriers that simply don’t align with other nations terms relating to cell phone replacement parts.

Marketing – Various marketing twists these terms just as much in an effort to advertise LCD screen parts in a manner that sounds more official and tends to keep the focus off some variant of the true condition.

For example: An “Original White LCD Display With Digitizer and Frame Assembly for iPhone 4S” listing title on eBay sounds like a 100% authentic LCD screen and must be “New” since the item condition reflects it being so.

– Other parts and components are reclaimed from broken LCD screens to make a refurbished LCD screen and could have other “aftermarket” parts used in re-manufacturing.

I scanned my inbox, Alibaba, eBay and Amazon for various sellers of iPhone LCD screens to get the most common terminology used in sellers’ offerings. I’ll list some of the most common terms used in product offerings below.

Terms like the above are mainly used to define one major component or part of the LCD screen rather than the word applying to all of the parts that make up an LCD assembly.

You get what you pay for. Most LCD suppliers are going to be in the same neighborhood in pricing. If you see a price that is significantly lower than another suppliers offering, you’re going to be giving up one of the following:

So if you went to buy the cheapest LCD screen from your supplier and asked “Are these new?,” they would most likely respond with “Yes.” In the example of Item #1, the LCD is new, but it’s a fake LCD that was made for the sole purpose of shaving cost. It will sacrifice something (if not a little bit of everything), including DPI and resolution, color brightness and quality of workmanship.

Asking very specific questions is half the battle when purchasing LCD screens from your supplier. The other half of the battle is getting an honest answer. Be very specific in the questions that you ask. I always try to use some common knowledge questions that don’t involve any of the terms used in conditions to eliminate any discrepancies in the answers you’ll receive. You should ask the following for questions specifically for all three major components of a typical LCD screen.

Digitizer – Is the Touch Panel manufactured by the same company that I would find on brand new in box phone that I purchased from an authorized Apple store?

The truth is: most buyers think they’re getting a new LCD screen when in fact 95% of the LCDs of replacement LCD screens for iPhone 4, 4s, 5, etc. are refurbished. The LCD screens that you purchase simply vary in the quality of the refurbishing process.

Toshiba and Sharpe are the only ones who made LCD screens for Apple iPhones and have not manufactured “new” ones for over a year. Those that they did manufacture were made for authorized service centers and over the counter replacements phones for post-paid carrier Asurion insurance customers only.

As of today’s date (Nov 11th), most LCD screen buyers are purchasing assemblies anywhere from $18-$26. A true new original would cost over $30 and actually be a bit hard to find. If you’re buying for under $30, you’re definitely buying a refurbished/reclaimed LCD screen.

When buying LCD screens and selling your broken LCD screens, many of the same terms are used, yet the industry treats these condition terms differently. Mainly, “Original” and “Non-Original” are used, yet the terminology of these conditions is different in regards to buying good screens and selling your bad ones.

Original– Never refurbished or reclaimed before. Example: if a retail customer bought a new iPhone 5 directly from Apple and it came to them brand new in the box, they cracked the screen, took it to your repair shop and you removed the screen to replace it; this LCD screen is original. Since the phone was opened and used as brand new in the box from official channels, the original (or FIRST) LCD screen that was on the phone has never been replaced.

Non-Original – The LCD screen has been refurbished or reclaimed from a broken LCD screen assembly at least one time. Non-Original does not mean fake. Illustrated below.

It can definitely start to get confusing when the same buying and selling words mean different things for the same product at a different stage in it’s lifecycle. When selling your smashed, cracked, damaged and broken iPhone and Android LCD screen assemblies, it’s usually best to translate “Original” and “Non-Original” to “Never Repaired or Refurbished” or “Has been Repaired or Refurbished” for easier understanding.

On most touchscreens there are usually two layers that make up just the digitizer. The glass on top that you touch and the actual digitizer sheet which consists of the touch matrix circuitry. The digitizer sheet is adhered to the glass so it often appears to be one piece. So you where correct to assume glass cover, digitizer and then lcd. The digitizer sheet and glass have a small gap that has an adhesive in it. On both the glass(bottom) and digitizer(top) is a transparent metallic conductive coating which is usually indium tin oxide. The human touch is conductive which allows for the electical sensors in the digitizer and glass sheets to sense the touch at a specific location.

Some of the newest technology such as Super AMOLED is able to get away from the two conductive sheets and has the touch sensors built into only one sheet, so these touchscreens would be an exception. So most forms of touchscreens consist of three or more layers.

Simply put, the digitizer is your iPhone’s touchscreen. In more detail, the digitizer is a glass panel that converts your touch into signals that your iPhone uses to do what you want. The digitizer is not actually the glass that you touch; it is underneath the top (protective) layer of glass. That’s why, generally, when you break the glass on your iPhone, your touchscreen still works. Check out Cell Phone City’s iPhone page for a quote to get your iPhone screen replaced.

On older iPhone models (4S and older) the digitizer was actually attached directly to the top layer of glass. That engineering (glass on glass) resulted in more cases of the touchscreen malfunctioning when the iPhone screen was broken. Newer iPhone models (iPhone 5 and newer) are built with the digitizer attached to the LED screen instead, leaving a few more layers on construction in between the top glass and the digitizer. This new construction offers better touch response, as well as some extra protection to the digitizer.

Most new aftermarket iPhone replacement screens have the old digitizer technology in them to cut down on costs. If you look at your iPhone screen replacement and it seems shinier than the original screen that cracked. Your eyes may not be playing tricks on you. When the digitizer is attached to the top glass it results in much more glare. The new replacement screens are responding well to touch, but do have subtle differences when compared to premium replacement and OEM screens. If you are having problems with the digitizer/touchscreen on your iPhone, contact Cell Phone City for a free inspection. We can let you know which kind of screen you have, and what can be done to improve the performance.

As often as you use your smartphone, it’s almost inevitable that you’ll eventually drop it. You may be extremely careful, but it only takes one fumble for your phone to tumble. While iPhone screens are designed to withstand impact, you might still end up with a shattered screen.

The good news: a broken screen doesn’t mean your phone is kaput. In fact, if only the glass is broken, the fix is quick and inexpensive. The bad news: if the LCD screen is broken, you’re looking at a pricier repair.

If you’ve looked into replacement parts, you’ve likely come across two very different options: a glass screen, and an LCD screen. While the first option is cheap, the second is definitely not. Here’s the difference:

1. The glass screen is the exterior layer on your phone’s display. While it is specially engineered for durability, it’s still just glass (between layers of plastic film), which is why it’s not very pricey to replace.

Most of the time, the damage to your screen will be pretty obvious. You’ll see the spider web patterns of shattered glass across the front of your iPhone. Occasionally, however, the glass screen will be intact, and you might not realize the damage until you try to use it. Whether the damage is visible or not, it’s a good idea to run a quick diagnostic to determine the extent of it.

If you encounter any of these problems, you’re dealing with a broken LCD screen. If the glass is shattered, but the display is clear and touch capability is working, that’s a good sign. The problem is probably just the glass screen.

Whether you’re dealing with cracked glass or a broken LCD screen, you can find a quick, reliable repair service at Our qualified technicians will get your iPhone repaired and up and running again in record time and at reasonable rates.
