Scratched touch screen

Types of Scratched Touch Screen

A scratched touch screen can happen on any touch screen – be it a phone, tablet, or a laptop. This is because users may apply more pressure on the screen when typing or scrolling, and over time, dust particles or sand in pockets can cause scratches on a soft glass surface. Generally, there are three main types of scratched touch screens:

• Capacitive Screens

  These screens work through the electric current of the human body. They have glass screens that detect touch through the change in capacitance at the point of contact. This screen is highly responsive, but the downside is that it can get scratched very easily. Capacitive screens are used on most smartphones and tablets. They are a preferred choice over resistive screens because they allow multi-touch functionalities. When scratches occur on a capacitive touch screen, the performance can be affected, especially in the detection of touches.

• Resistive Touch Screens

  Resistive screens have a softer touch screen with two layers of polyester that work together to detect touch by a pressure point on the screen. They are less responsive and, therefore, work well with a stylus pen or a little pointed finger. Although they work pretty much the same way as capacitive screens, resistive touch screens are below capacitive touch screens in functionality and performance. However, they are more durable, and the scratches will not affect touch sensitivity or functionality.

• In-Mold Decoration Touch Screens

  IMD touch screens are decorated and designed in the mold and then coated with glass. This gives the screen high durability and resistance to scratches. The touch screens are used on home appliances due to their high-quality finish and resistance to scratches. Since IMD screens are coated with glass, scratches on the surface will not affect the touch sensitivity or the functionality of the screen. It also retains its aesthetic appeal for long periods.

Functions and features of scratched touch screens

People put various functions and features on touch screens to make them stronger and better. Here are the main functions and features of scratched touch screens:

• Protection Against Scratches

  Coated touch screens protect against scratches that may be caused by pens or other tools. They enable the touch screen to stay smooth and responsive throughout its lifespan.

• Fast Touch Sensitivity

  Fast touch sensitivity on durable touch screens ensures instant response to every touch. This will improve the screen's performance and offer a good user experience. Strong touch screens with good response time function well in electronic devices that need high efficiency.

• Environmental Resistance

  Many kinds of scratched touch screens perform well in different kinds of environments. For example, inside industrial areas, outside in the weather, or even areas with a lot of germs. The good resistance can quickly handle issues like high temperatures, humidity, or exposure to chemicals. These touch screens are ideal for harsh environments.

• Multi-Touch Capability

  Durable touch screens with multi-touch capability allow more than one touch to be recognized at the same time. Games and apps function better because the multi-touch feature supports zooming and rotating gestures on the scratched touch screen. This feature makes it easy for people to use their devices and do more things at once.

• Stylus Compatibility

  Some touch screens allow styluses to be used. They offer better accuracy and control when users draw or write on the screen. Stylus compatibility is important for apps used for graphic design, taking notes, or doing calculations. These screens give users the exact and responsive input needed for professional jobs and creative tasks.

• Impact Protection

  The toughened glass panels stop cracks or shatters that can happen when the screens get hit. Devices that are used in fieldwork or in areas that are prone to sudden falls and impacts work well with these screens because they have good impact protection.

Applications of Scratched Touch Screen

Touch screens have a wide array of applications, from ATMs, and car dashboards to smartphones. In the aftermath of a scratch on a touch screen, the specific screen can be repaired depending on the technology used. For scratched screens on devices with capacitive touch screens, the following application can be used to repair the scratches and bring back the aesthetic value of the device.

• Liquid glass: Also known as liquid nano coating, this repair option is more preventive than curative. The repair option fills in the microscopic gaps on the screen's surface to create the illusion of a smoother and scratch-free screen. Liquid glass can be applied to a scratch touch screen to prevent further scratches. To apply liquid glass, the screen should first be cleaned with a microfiber cloth. Next, apply and spread the liquid glass solution evenly on the screen and allow it time to cure according to the manufacturer's instructions. Finally, buff the screen with another clean, dry microfiber cloth. The result of this application is a scratch-resistant touch screen that retains its original clarity. It is important to note that liquid glass only works on minor scratches.
• Screen protector: For minor scratches on a touch screen, a screen protector can be an instant fix. If a scratch touch screen has a screen protector, the protector's layer can mask the scratches providing an illusion of a smooth touch screen. Additionally, a screen protector provides a further protective layer against future scratches. There are different kinds of screen protectors available on the market. Choose a screen protector that is compatible with the device's model. This compatibility will ensure that the cutouts for buttons and camera placements align properly without interfering with the user's touch response. To apply, clean the screen first. Then, carefully align the protector with the screen's edges and any cutouts, and finally peel off the protective backing and press down on the adhesive side.
• DIY scratch filler kits: These kits often include a liquid solution, applicators, and a polishing cloth. The liquid solution is designed to fill in the scratch, and the process usually involves applying the solution to the scratch, wiping off any excess, and then polishing the area with the provided cloth. It's essential to follow the instructions carefully. The instructions may differ depending on the manufacturer.

  How to choose scratched touch screen

  It is essential to understand the type of raw materials used to make scratched touch screens when choosing one. Because not all touchscreens are created equally, the screen is more prone to scratches based on the type of glass.

  Look for screens that use Corning Gorilla® Glass (GEN) - Enhanced touch. The Corning® Gorilla® Glass touch screens respond well to casual touch, including gloved, stylus, and wet-hand touch, with a smooth surface like that of an untreated glass. They are three to five times stronger than traditional glass and have excellent scratch resistance. The company offers different screen sensitivity levels based on the application.

  If the scratched touch screen will be used for outdoor applications, consider the anti-glare touchscreens. They reduce the screen's surface reflectivity and maximize light transmission, ensuring good optical clarity.

  Another essential factor to consider when selecting the right scratched touch screen is to understand the kind of device it will be mounted on. Be sure to measure the mounting bezels well to ensure the scratched screen fits appropriately.

  Also, keep in mind that scratched touch screens tend to vary in thickness. The screen thickness ranges from 0.2 mm to 20 mm. Be sure to select the appropriate thickness to ensure the display device is not too thick or too thin.

  When selecting a scratched touch screen, it is also wise to consider the quantity. Multiple suppliers sell scratch-resistant touch screens in bulk; hence, purchasing in bulk might land buyers a better deal.

  Consider the lead time of the supplier. If the buyer wants the screen for urgent use, it would be wise to choose a supplier with a short lead time. Communicating with the supplier is critical in ensuring the buyer's needs are well met.

  Understand the supplier’s warranty terms. Be aware of how the supplier handles screens with defects. Do they send a new screen once a buyer proves there is a defect, or do they send a new screen if the buyer requests it after reviewing the first shipment?

  Finally, check reviews to ensure the supplier delivers high-quality scratched screens. Reviews often help reassure the buyer that they are making a sound decision to purchase from a specific supplier.
