What is a touch screen?
A touch screen is an equipment that allows you to engage with devices by touching the screen. You can use a finger or stylus pen to perform different tasks on a touch screen device. It means you can input data using the display.
Why is the touch screen important?
Touch technology is useful for users who have little know-how of technology. It is much more manageable and straightforward as compared to traditional methods.
The touch screen excludes buttons and keys, thereby providing more screen size for the panels.
Using a button in the nighttime is difficult, but the touch screen eliminates all light issues nighttime.
What are the workings or components of a touch screen?
Components of touch screens commonly consist of a touch sensor, controller, and software driver.
The sensor is used to detect the signal when we touch the screen with a finger or stylus pen. It detects the exact location using a signal or electrical current sensing technology.
Touch Controller exists between the touch sensor and hardware part of the computer. Its responsibility is to receive a message from the sensor and translate it into a computer understandable form. Moreover, it detects what type of connection is required.
The software drivers’ responsibility is to allow hardware and touch screen panels to work collectively.
It informs the event of the controller to the operating system detected with touch.
The first most popular touch device is the resistive touch screen. It includes different wired models like 4,5,6,7, or 8 wired-resistive models, and the most common one are 4 wire resistive touch screen and 5 wire resistive touch screen. This is a more stylus-friendly touch, but a few resistive contacts are also finger-friendly. LG Optimus Android Smartphone and Palm Centro are examples of resistive touch screen sensing technology.
• A resistive touch does not cost much money.

• It can also be activated with finger, stylus, pen, or screen gloves.
• Moreover, its power consumption is low.
• It provides resistance from dust, oil, and moisture.
• It does not offer the functionality of multi-touch.
• Further, these provide lower image quality when compared with other types.
• Its outermost layer is vulnerable to Scratches, and damages occur.
Capacitive touch screen sensing technology
The second most popular technology is the capacitive touch screen. It is mostly used for industrial purposes. Capacitive touch provides multi-touch and finger-driven capability. The touch accepts the electrical charge and provides a location on the screen to work.
• These provide multiple functionalities and are easy to use.
• These are used in smartphones, and tablets such as IPad, Galaxy, and XOOM are examples of capacitive screens.
• The main advantage is the image clarity more than resistive touch. It provides resistance to scratching.
• It is activated using touch gloves.
• These screens are costly.
• You cannot use a touch stylus or fingernail for this technology.
Surface Acoustic Wave (SAW) consists of a reflector and two transducers placed on a glass surface. Touch is detected when waves absorb. Surface wave technology has advantages over capacitive technology and resistive screens. Parameters like image resolution, clarity, accuracy, and light transmission are better than others.
SAW monitors have high visibility and are easy to use.
• SAW (Surface Acoustic Wave) provides the best resolution, clarity, and durability.
• SAW (Surface Acoustic Wave) can be used with a stylus and gloves.
• SAW has better scratch resistance.
• SAW cannot be activated with hard items like pens and fingernails.
• Unwanted actions may be performed due to water droplets.
Infrared sensors are used in the Infrared touch to sense heat from the user’s finger. Infrared screens provide the best image quality.
• These provide the best light transmission and high clarity of the image.
• Surface scratches do not impact much in this technology.
• These cost higher and may be sensitive to rain and water.
So these were a few touching technologies that you can select. It is clear that these technologies have a significant impact globally and provide easiness to human beings.
It is important to decide that the software drivers supplied with the touch are well-suited. The latest version of the user’s operating system after the touch screen technology and controller has been selected.
Here I have listed the most significant factors that you should consider when purchasing a touch screen,
Durability and Scratch Resistance
Traditional touch screen panels were more vulnerable to scratches. That’s why they require costly protective glasses. Similarly, they are less durable. But the latest ultra touch screens can resist scratches and are more robust. So always go with ultra touch screens.
No other factor is more important than the response time. This depends on the processer being used in a device and the touch sensor. The processor determines the overall performance, but without a suitable touch sensor, it cannot do its job alone.
Another essential factor is water resistance. This is particularly important in the industrial setting. Because a capacitive touch screen might perform automatic functions if a drop of waterfalls on it. This may result in false command. So while purchasing a touch screen, make sure it is water-resistant. Particularly, when it is to be used in some sensitive industrial or medical situation.
Touch technology devices need more battery to run the display. Most smartphones require the frequent running of resources in the background. That is why these consume a lot of battery. Power consumption major source is watching videos on a larger display.
This feature involves the ability to use both fingers simultaneously to perform actions on the display unit. With different smartphones, you can perform a zoom-in and zoom-out using both fingers simultaneously.
Stylus and Pen Supportive
Some touch screens work with stylus pens, and others don’t. If you are a designer, you need to select touch screen devices that support a stylus pen. Mostly capacitive touch screens support this function.
In industrial devices, the standard operating procedures require gloves. So for industrial machines, when you select a touch screen, make sure it supports gloves. Gloves are specially designed for many touch screens. That is why it is crucial to keep in mind the availability of gloves for a particular touch panel.
