lcd screen vs digitizer in stock

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.

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.

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.

LCD (Liquid Crystal Display) – is the part of iPad that respond for image. In most models it could be replaced without replacing the digitizer, but not in all.

When you Apple iPad Mini 5 looks like broken TV or has some lines, image is shaking or it doesn’t turn on you might need to get your LCD screen replaced.

I need to replace my cracked digitizer/glass on my OnePlus One and it seems changing only the digitizer is kinda hard so next thing is to get the full LCD to replace.

It seems logical that lcd + frame is easier but it seems it requires to move components/motherboard around which for me seems more prone to mistakes and problems then just buying an LCD and putting it into my old frame.

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.
