damage lcd screen by touching manufacturer

-“These chemicals are semi-liquid and can get into the environment at any time during manufacturing and recycling, and they are vaporized during burning,” said University of Saskatchewan environmental toxicologist and lead author John Giesy in a press release. “Now we also know that these chemicals are being released by products just by using them.”

-If you crack LCD screens and find the liquid crystal leakage, don’t panic. Just remember that the liquid crystal materials might not be more toxic than your detergents for stove or washroom. Just wash your hands with soup throughout. Never try to play with it or even worse to taste it. The liquid of the cracked computer screen will not evaporate, no emissions worries.

-Any electronics has environment impact and can’t be used landfills. If you want to get rid of old LCD monitors or LCD TVs, give them to electronic collection stations. Let’s the professionals to handle them. They will extract some precious metals/parts and make them into something useful or at least not hazard. FYI, liquid crystal materials are retrievable.

Accidental Damage is any damage due to an unintentional act that is not the direct result of a manufacturing defect or failure. Accidental damage is not covered under the standard warranty of the product. Such damage is often the result of a drop or an impact on the LCD screen or any other part of the product which may render the device non-functional. Such types of damage are only covered under an Accidental Damage service offering which is an optional add-on to the basic warranty of the product. Accidental Damage must not be confused with an occasional dead or stuck pixel on the LCD panel. For more information about dead or stuck pixels, see the Dell Display Pixel Guidelines.

No, accidental damage is covered for Dell computers or monitors which are covered under the Accidental Damage Service offering for that specific product.

For more information about Dell Limited Hardware Warranty and Dell"s Accidental Damage service offering, see the Dell Warranty & Support Services page.

NOTE: Other damages may be considered customer induced if determined by Dell Technical Support, an on-site field engineer, or at the mail-in repair center.

The LCD glass on the display is manufactured to rigorous specifications and standards and will not typically crack or break on its own under normal use. In general, cracked, or broken glass is considered accidental damage and is not covered under the standard warranty.

Internal cracks typically occur due to excessive force on the screen. This can be the result of some object hitting the screen, a drop, attempting to close the lid while an object is on the keypad area, or even holding the laptop by its screen.

Spots typically occur due to an external force hitting the screen causing damage to the LCD panel"s backlight assembly. While the top layer did not crack or break, the underlying area was compressed and damaged causing this effect.

If your Dell laptop LCD panel has any accidental damage but the laptop is not covered by the Accidental Damage service offering, contact Dell Technical Support for repair options.

Dell monitors cannot be repaired by an on-site field engineer or at the mail-in repair center. If you notice any damage to the monitor, you must purchase a new monitor.

Dark spots or patches may occasionally appear on some liquid crystal display (LCD) panels. This clouding phenomenon is recognized in the industry as YOGORE or "Mura", a Japanese term for "unevenness." This term is used to describe a low-contrast, irregular pattern or region that causes uneven screen uniformity under certain conditions. Mura is a result of the deterioration of the liquid crystal (LC) alignment layer; most commonly caused by long-term operation under high ambient temperatures. It is an industry-wide phenomenon and Mura is not repairable.

Elo Mura specificationsMura-like image retention is not covered by the Elo TouchSystems product warranty.The visual performance of liquid crystal displays (LCDs) has usually been evaluated by visual inspection. One of the visual problems hardest to recognize are regions of low contrast and non-uniform brightness or Mura. The accurate and consistent detection of Mura is extremely difficult as it can appear in various shapes and sizes and the inspection results tend to be subjective and based on opinion. As Mura does not lend itself to quantitative measurement, no specification for Mura is available.KB#000002625

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.

Fortunately, your mobile device is fixable whether you cracked the glass or damaged the LCD. Stop by or call TCR: Triangle Cellular Repair at (919) 263-2699 for a free diagnostic and quick, affordable cell phone repair in Chapel Hill and surrounding areas. We’re always happy to help!

Touchscreens are a popular type of LCD module that can be found in various devices these days. These are used by manufacturers of smartphones, computers, laptops, ATMs, navigation systems, and point-of-sale-terminals, among other devices.

There are two types of touchscreen technology: resistive and capacitive. Resistive is the one that uses pressure to draw a response while capacitive relies on the human body’s electrical properties. Given this, it takes light pressure applied by a finger or stylus for the resistive touchscreen to work. On the other hand, capacitive touchscreens won’t respond unless it senses energy from the human body.

Knowing the different types of a touchscreen LCD display moduleisn’t enough in deciding which to choose for your project or business. You also need to understand the different problems encountered by each technology and be prepared to handle them.

Proper calibration allows the touchscreen technology to sense where the screen is being touched so that it can accord the command to a screen’s response. When the screen loses proper calibration, it will not be able to provide the correct response. Sometimes the screen will not even be able to detect a touch. This negates the device’s purpose for consumers. To fix this problem, the screen must be re-calibrated.

Since touchscreens are mostly engaged by fingers or other means that are exposed to foreign substances, it’s prone to being scratched or damaged. Dirt and grease transferred through touch or the stylus may also appear on the screen and affect its function. When the screen is damaged, it will not be able to provide accurate responses. Some parts of the screen may not even function at all. You can prevent this by using screen protectors and cleaning the device regularly.

Even if you’re taking good care of the screen, the system itself may develop problems over time. The device system may not be able to register user inputs or become slow and unresponsive with age. When this happens, you can try re-calibrating the screen and refreshing the system to see if it helps.

These problems are common with touchscreen technology, even with proper maintenance. The key is in understanding the causes of these problems so that you can prepare for them and know what to do when they are encountered.

Even on screens that aren’t meant to be touched (e.g. not a touchscreen!) a simple tap or swipe with a fingertip, where the screen is not visibly deformed, won’t do any harm except maybe to leave behind a little skin oil.

But — of course! — if you press any screen with a sharp object, you may damage its covering; and if you press very hard even with your finger you may damage the internal components of the screen.

BTW: Most screens sold as “LEDs” are still actually LCDs, but with an LED backlight. Only “emissive” technologies, such as xOLED, are true LEDs with no backlight.

Superior optics for use in high ambient light conditions and high accuracy are important characteristics of touch screens used in the medical industry. It is also important that these units are properly sealed to protect against ingress of water, saline, gels, cleaning solutions and other liquids the unit may be exposed to in the healthcare environment.

Pressure damage usually happens by accident when transporting or cleaning an LCD screen. To avoid this type of damage, use extreme caution whenever moving a screen. If your screen is on a laptop, always place it in its carrying case when not in use. If your LCD screen is larger, like a television, try to avoid touching the LCD surface altogether during transport.

When cleaning an LCD screen, use a combination of water and isopropyl alcohol or vinegar. Harsher chemical cleaners can damage the screen. Never apply the solution directly to the LCD monitor; instead, apply it first to a soft cotton cloth. Gently wipe the screen in one direction. If you come across a spot that is harder to clean, resist the temptation to apply pressure. Instead, continue wiping the screen in one direction -- preferably from top to bottom -- until the spot comes off.

If you store your LCD, make sure never to place anything on top of the screen. Even light objects can, over time, apply enough pressure to leave a permanent mark on your screen.
