The Benefits of Resistive Touch Technology
What is resistive touch? Resistive touchscreens are basically touch sensitive resistors (or capacitors) that are built into the screen of your laptop or mobile computer. A resistive touch screen is simply a thin touch-sensitive surface made up of two flat sheets of thin resistive material covered by an invisible resistive barrier or air gap. The resistivity is measured in Ohm’s – one ohm is a diode voltage and the higher the Ohm value, the smaller the resistive barrier. This means a resistive touch screen has a much smaller footprint than the resistive LCD or plasma screen. Because resistive touch screens are thinner, lighter, and much less expensive, the resistive option becoming more common in portable and tablet computers.
Resistive touchscreens are available in two forms, capacitive and resistive. Capacitive touchscreens use the mechanical act of touching the screen to register the light from a stylus, scanner, or other device. This type of screen uses very tiny finger pressure to register a particular point of light. A resistive touch screen works based on the same principles but instead of using finger pressure, it relies on the presence of other active elements such as a resistive current, an electrical charge or even an infrared light. Capacitive touchscreens rely on the principle that the lighter a finger is, the faster the information can be processed.
While both types of touchscreen have their advantages, resistive is substantially more efficient than capacitive. Capacitive-based resistive touchscreens rely on a passive resistive current to activate the capacitance, meaning that the current doesn’t flow through holes in the resistive layer. However, resistive touchscreens must be charged, which increases the battery drain cycle. In contrast, resistive touch screens don’t require any additional steps to be taken during the charging process. If you are thinking of purchasing a touchscreen, resistive may be a better option.
Most touchscreen devices today come equipped with resistive screens. Some manufacturers, however, have started adding resistive touchscreens as an after-market feature. Although some manufacturers still include resistive touchscreens as standard equipment, this isn’t always the case. If you’re looking for one of these devices, your best bet is to go online and look for consumer reviews. Resistive touchscreens have consistently received high ratings, making them a great choice for many consumers.
There are several differences between resistive and capacitive touchscreens. For example, resistive touchscreens rely on the physical act of touching the screen to register a point of light. With capacitive touchscreens, you need to make contact with the screen with your finger. With a capacitive touch screen, you make contact by pressing the screen with your finger. This is why some people don’t prefer capacitive touchscreens; they have experienced too many “pressing and holding” when using their devices.
One of the main reasons resistive touch technology is becoming more popular is the availability. Capacitive touch technology is very difficult to find because it is only available in certain applications. However, resistive touch technology is widely available. This means that more consumers than ever before are opting to buy a resistive screen rather than a capacitive one.
Another advantage to resistive touch technology is the cost. Touch screen devices, especially those used for industrial applications, generally cost thousands of dollars. resistive touchpads, on the other hand, can be purchased for well under $100. This makes pcap technology a great choice for anyone looking for a cost effective alternative to resistive touch screens.
The final advantage to resistive touch technology is optical clarity. When using a resistive touch screen, the image displayed on your device is the result of a series of resistive contacts interacting with one another. There is no pixel where an optical fiber or other optical media could be used in order to display the image. This means that resistive touchpads provide a much clearer image than their capacitive counterparts. Capacitive screens often display images with streaking, chipping, or smearing. With resistive touchscreens, there is no streaking, chipping, or smearing, which means that you get an image with absolutely perfect resolution.
