Touch Screen Technology & All you Need to Know

Mobile and computer technology are constantly changing due to technological advancements. In the past, we accessed the main device using external gadgets such as a mouse, keyboard, and other peripherals. But the invention of touch screens made it easier to interact with mobiles, computers, and other devices.

What is a Touch Screen?

Simply speaking, a touch screen or touchscreen is an input device that allows users to interact with the main device. Users can manipulate their devices using single or multitouch gestures. A touch screen display has three main parts: the protective glass sheet, the digitizer sheet, and the LCD panel.

What is a Touch Screen Digitizer?

A touch screen digitizer is also known as an LCD digitizer. The digitizer is an integral part of every touchscreen display. A touch screen digitizer is a thin transparent sheet or piece of glass that converts analog touch into digital signals. When a user touches the display to process something, the display transfers the command to the digitizer, which converts it into a digital signal.

What is an LCD in Touch Screen?

The full meaning of LCD is Liquid Crystal Display, and LCD is one of the main components of touch screens. LCDs (Liquid Crystal Displays) are super thin and fragile components inside touch screens that display images. It is only possible to get to the LCD by disassembling the device.

Brief History of Touch Screen

According to Wikipedia, the LG Prada, which was released in May 2007, was the first mobile phone with a touch screen. However, after the iPhone was released in 2007, the touch screen became wildly popular. 

Different Types of Touch Screen

It is not necessary to use an external mouse and keyboard to operate the touch screen. Keyboards and mice are replaced by touch screens. However, there are five different types of touchscreen monitor technology. They are listed below

• 5-Wire Resistive Touch screen
• Surface Capacitive touchscreen
• Projected Capacitive (P-Cap) touchscreen
• SAW (Surface Acoustic Wave) touchscreen
• IR (Infrared) touchscreen

Use Cases of Touch Screen

In the last few decades, touchscreen technology has revolutionized the way we interact with technological devices. More and more devices are coming with touch screen displays nowadays, and we can see them everywhere. Below is a list of the most common touch screen devices:

• Mobile phones
• Laptops and Computers
• Tablet computers
• Watches
• ATM (Automated teller machine) machines
• Point-of-sale (POS) terminals
• Car navigation systems
• Medical monitors

It is possible to use touch screen displays anywhere. This is a very convenient way to interact with the machine.

When Should I Replace Touch Screen?

You can break your favorite phone with just a drop. However, if your phone screen is broken and not responding, you will need to replace the display screen with a digitizer assembly. If you are lucky and your touch screen works, then you only need to replace the front glass. A front glass replacement is less expensive and easier.
