touch digitizer vs lcd screen quotation

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.

• Perform highly diversified duties to install and maintain electrical apparatus on production machines and any other facility equipment (Screen Print, Punch Press, Steel Rule Die, Automated Machines, Turret, Laser Cutting Machines, etc.).

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.

I know this is really, REALLY old but just in case somebody else ends up here looking for an answer I thought this questions deserved one. On the Surface Pro 3, as in other Surface models, the digitizer comes as an assembly with the screen. They must be replaced together. This is not to be confused with earlier models that also had a separate digitizer BOARD that connected to the main board, that would go out occasionally and also need replacement (Rarely, many of these were replaced for no reason simply because it was the cheaper part).

Now, about that assembly I mentioned. You must be sure to purchase the correct version. The early LCDs that were released were faulty and would not run properly on the default resolution. You are looking for a V.1.0 or V.1.1. 99% sure it is a V.1.1. Anything lower than that is going to be a problem. They are a different make and not compatible unless you have a very early release unit. Shop around and pay attention. Not all LCDs are created equal. The same can be said of touchscreen digitizers. Some of them you will plug in, go to test, power it up and it won"t work. It will detect, load the numerous touch drivers(8 I think?) then nothing. Others seem like they have to "warm up" for some reason and will suddenly start working later.

The point of all this is to say you should buy an assembly from a reputable dealer and be sure that 1: the LCD is compatible and will display correctly and 2: the digitizer will function properly. I can not stress enough how important it is to get this right, because these assemblies are EXPENSIVE. At the time of writing this they are still around $300+. Thee is a reason you can find SP3s on ebay with cracked screens for under $100 all day. At that price, and because of the total unmitigated nightmare the SP3 is to open up and work on to begin with, and the fact that you may get all this right and still have issues because you don"t have a way to properly calibrate the darn thing and have to send it into Microsoft to anyway which you could.. NAY SHOULD have just done to begin with!!

However, if the digitizer or LCD is also damaged during a fall, that screen no longer carries value because it cannot be refurbished. Repair shops cannot sell broken LCDs to refurbishing companies; therefore, they cannot offset the cost of an LCD repair. That is why repair stores often charge a little extra if there is damage to the LCD or digitizer, to make up for that loss. Repair stores that don’t have an additional charge for an LCD repair typically inflate their glass repair price to make up for the loss from damaged LCDs. If they have one price, that means everyone is paying more to cover the cost of customers who have damaged LCDs and customers who only have cracked glass. This is why TCR separates the price of glass and LCD repairs for you! If you only have cracked glass, you only have to worry about paying to replace the cracked glass.

If your phone or tablet’s glass is shattered there will be cracks or chips on the screen itself. If it is just the glass that is damaged, the device may still function and you may be able to use it normally. If this is the case, it is likely that only the glass needs to be replaced. To prevent further damage to your device it is best to get it repaired quickly. For example, if liquids seep through the cracks it could cause permanent damage to the LCD.

Many people may continue to use their touchscreen with shattered glass and delay fixing the glass on their devices; however, if the touchscreen isn’t responsive, it could be a sign of more significant damage to the device’s digitizer which is integrated with the LCD screen.

A pixelated screen can indicate LCD damage. This would look like a patch of multicolored dots, a line or lines of discoloration, or a screen with rainbow colors. For many people, these colors are an easy way to know that their LCD is broken and that they should get it repaired.

Dropping your phone isn’t the only reason you’ll end up with a pixelated screen. Over time, your screen’s LCD may break down through regular use. This happens to other devices aside from your smartphone or tablet. Pixelation can happen to TVs and computers, too. People typically decide to buy a new device when this happens. Fortunately, with an LCD repair, you can fix the device without needing to replace it.

A black screen or black spots on your smartphone or tablet is an indication of a damaged LCD. Often with a bad LCD, a phone may still turn on and make noises, but there is no clear picture. This does not necessarily mean any other part of the phone is damaged and a simple screen replacement will get it functioning again. Sometimes it can mean a battery or other internal component is damaged. It is best to have a highly qualified phone repair technician diagnose what is wrong so the appropriate repair can be made.

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 FastPhoneRepair.com. Our qualified technicians will get your iPhone repaired and up and running again in record time and at reasonable rates.

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.
