Extensive use of touchscreen can be noticed in various devices including smartphones, tablets, PCs. These touch screens, typically driven by touch in consumer electronics, use two types of technology. One is capacitive and the other is resistive; Resistive touchscreens are more commonly used in older and cheaper mobile phones. At present, capacitive technology is taking up most of the space for touchscreen smart devices. But what is the difference between these two types of screens? That is what we will discuss in this post.

Resistive touchscreen

Apart from modern smartphones, trackpads and tablets, a large part of the touchscreen we see has a resistive touchscreen. These depend on resistance to work

Law. A resistive touchscreen has more than two layers. At the top are two thin layers. Each of these has a special coating or coating and the two coated sides are set facing each other. There is a fine space between the two layers.

When you press on any part of the resistive touchscreen, these two layers come in contact with each other and electricity flows. Touch-sensitivity is created in the corresponding position by utilizing this signal. If there is not enough pressure on the resistive screen, it will not respond. That’s why

Most users feel comfortable with a capacitive touchscreen. Besides, they do not have multitouch gestures like ‘pinch to zoom’ etc. Having many layers also affects the display graphics quality.

Capacitive touchscreen

Although resistive displays can be seen in the devices with touch screens like earlier smartphones like Nokia N series, E-series, etc., it is surprising but true that the capacitive screen has been discovered earlier. Resistive screen innovation is almost 10 years ago The advent of capacitive screens. But at first their skills were not as good as they are now.

On the resistive touchscreen you can touch and operate with a finger, pen, stylus or anything. These mainly depend on the mechanical pressure.

But the current flow is used differently in capacitive touchscreens. These displays have a glass (transparent and hard) layer on the outside so that Capacitive sensing The technology is used. This part contains the conductive layer which changes its electrical properties when touched by any other conductive object. Capacitive touchscreen takes input with the signal from this change. Touching a capacitive touchscreen with an electrically conductive stylus or any other object does not elicit a response. However, at present some ‘super sensitive’ capacitive touchscreens can be operated even after gloves. For example, Nokia Lumia 920 smartphone Get this benefit. Nokia has not officially revealed the technology behind this.
