How to Repair a Capacitive Touch Screen and Its Applications

Understand how to fix common issues with capacitive touch screens and explore their use in consumer electronics, automotive, and more.
Capacitive Touch Screen

A capacitive touch screen is a type of touch display that recognizes and responds to touch by measuring changes in capacitance. 

Unlike touch screens that depend on pressure to detect touch, capacitive screens work by sensing the charge of a conductive object, such as a finger or stylus. 

This technology offers benefits like high touch sensitivity, multi-touch capability, and durability.

Is the iPhone a capacitive touch screen?

Absolutely, the iPhone comes equipped with a capacitive touch screen. 

Apple transformed the smartphone market with the debut of the iPhone in 2007 highlighting the responsiveness and intuitive interaction made possible by capacitive touch technology. 

The iPhone’s capacitive touch screen enables users to navigate the device using gestures, like tapping, swiping, and pinching providing a user-friendly experience.

What are the two types of capacitive touch screen?

Touch Screens

Capacitive touch screen types are categorized into two, which are the projected and surface variations.

Projected Capacitive Touch Screens (PCT) consist of a layer of material applied on a glass substrate with electrodes positioned along the edges. 

This design allows for touch detection and supports multi-touch gestures. 

PCT screens are commonly found in smartphones, tablets, and various other consumer electronic devices.

On the other hand, Surface Capacitive Touch Screens (SCT) are constructed with a glass panel covered in a material, like indium tin oxide (ITO). 

The screen has electrodes placed at its corners and touch recognition is based on changes in capacitance resulting from the user’s touch. 

These screens are known for their durability. 

Moreover, you can find their applications in public kiosks, point-of-sale systems, and industrial settings. 

Capacitive Touch Screen Repair: Simple Steps to Follow

When it comes to fixing issues with touch screens, the approach varies depending on the type and severity of the damage. 

Problems commonly encountered include touch function, spots on the screen, and scratches. 

Here are some steps you can take to troubleshoot these issues:

Step 1

Clean the screen using a cloth and mild cleaning solution to remove dirt, fingerprints, and smudges. 

Step 2

Next, try restarting the device to check if this improves touch responsiveness. 

Some devices offer options to recalibrate touch screen settings for enhanced accuracy and responsiveness. 

Step 3

Additionally, it’s advisable to look out for firmware or driver updates that could potentially resolve any touch screen problems.

If, despite troubleshooting attempts, the touch screen remains physically damaged or unresponsive, it might be necessary to replace the screen. 

Seek professional repair services immediately.

Capacitive Touch Screen Parts

Touch Sensor

This component acts as the touch-sensitive layer that registers touch inputs. It is commonly crafted from a material, like ITO, and is situated on the screen’s top surface.


Responsible for processing touch input signals received from the touch sensor the controller interacts with the device’s operating system to interpret user interactions.


Serving as a support system for both the touch sensor and controller components the substrate is typically constructed from glass or plastic materials.


These conductive elements are strategically positioned along the edges or corners of the touch screen. 

They play a role in transmitting signals to the controller and aiding in touch input detection.

Where Are Capacitive Touch Screens Used

Capacitive touch screens are typically used in the field of consumer electronics including smartphones, tablets, laptops, and wearable technology devices.

This technology is also used in the automotive sector where touch screens are utilized for vehicle infotainment systems, navigation displays, and touch-sensitive controls.

Moreover, capacitive touch screens are crucial in the retail industry, especially in point-of-sale terminals, self-service kiosks, and digital signage solutions.

Additionally, some industrial applications including control panels, human-machine interfaces (HMIs), and various factory automation systems also use capacitive touch screens.

Lastly, the healthcare field also uses capacitive touch screens for patient monitoring systems and diagnostic equipment.
