Touch screens are a familiar sight, from the smartphone in your pocket to the self-service supermarket checkout. Touch screens are intuitive and easy to use and make interactions with technology much quicker.
Laptops with touch screen technology are now a common option, but how do they work, and should you have this feature on your list of requirements next time you look for a new computer from the range of HP touch screen laptops?
How touch screens work
There are two main types of touch screen technology, resistive and capacitive.
Resistive technology touch screens work by detecting the pressure of an object, such as a finger or a pen, pressing against the screen. It does this by making the screen from two conductive layers with a separating layer of insulating material. Pressing on the outer layer reduces the space between the two layers, reducing the resistance. Circuitry attached to the screen detects this change and works out precisely where this change occurred.
Even if you are extremely careful with your hardware, it can be unavoidable at times to run into issues such as a cracked or broken computer screen. Just because you’re experiencing problems with your display doesn’t mean that your laptop is beyond saving, however.
