Are you tired of dealing with a touch screen that’s as responsive as a brick? Don’t worry, you’re not alone. Touch screen malfunctions are more common than you think, and in most cases, they can be fixed with a few simple tweaks or DIY repairs. In this article, we’ll take you through the steps to diagnose and fix common touch screen issues, so you can get back to swiping, tapping, and pinching your way through your favorite apps and games.
Understanding Touch Screen Technology
Before we dive into the troubleshooting process, it’s essential to understand how touch screens work. There are several types of touch screen technologies, but the most common ones are:
Resistive Touch Screens
Resistive touch screens consist of two flexible plastic sheets separated by a gap. When you touch the screen, the sheets make contact, and the point of contact is registered as a touch event. Resistive touch screens are relatively inexpensive and durable but can be prone to scratches and damage.
Capacitive Touch Screens
Capacitive touch screens, on the other hand, use a layer of glass or plastic with a conductive coating. When you touch the screen with your finger, your body acts as a conductor, allowing the screen to detect changes in capacitance. Capacitive touch screens are more responsive and accurate than resistive touch screens but can be more expensive and prone to interference.
Common Touch Screen Malfunctions
Now that we’ve covered the basics of touch screen technology, let’s take a look at some common malfunctions and their symptoms:
