Should You Choose a Capacitive or Resistive Tablet?
When shopping for a tablet computer, you'll need to choose the right touchscreen technology. Some tablets use capacitive technology to detect and respond to touch commands, whereas others use resistive technology for this purpose. Capacitive and resistive tablets aren't the same, however. They each use a different mechanism to detect and respond to touch commands, resulting in different benefits for capacitive and resistive tablets.
How Capacitive and Resistive Tablets Work
What's the difference between a capacitive and resistive tablet exactly? Capacitive tablets feature a capacitive touchscreen interface that leverages the human body's electrically conductive properties to identify touch commands. They emit an electrostatic field that changes in response to a conductive object, such as your bare finger. Capacitive tablets will register these changes as a touch command.
Resistive tablets work by using layers of an electrically resistive material, which contain embedded electrodes. Performing a touch command will press these layers together so that the electrodes touch each other.
Benefits of Capacitive Tablets
In terms of popularity, capacitive tablets are at the top of the list. Most tablets manufactured and shipped, in fact, use capacitive technology. One of the reasons for their popularity is a superior level of sensitivity. You don't have to press or touch them forcefully. Rather, you can gently place your finger on a capacitive tablet's touchscreen interface to perform a command.
Capacitive tablets also tend to last longer than resistive tablets. Resistive tablets have multiple layers. Each time you perform a touch command, these layers will move. Over time, the constant movement of a resistive tablet's layers can cause it to fail. Capacitive tablets don't have moving layers, nor do they have any other moving parts. As a result, they typically last longer than resistive tablets.
