Resistive Touch Screen Capacitive Touch Screen Advantages Inexpensive Higher touch sensitivity Better resistance to dust and water Supports mulit-touch Can be used with gloves Good visibility even in sunlight Disadvantages Low touch sensitivity Cannot be used with most gloves Unable to support multi-touch More expensive Poor visibility in sunlight Does not work well with pointed objects.
One striking difference between resistive and capacitive touchscreen devices involves their method of input. With capacitive devices, users are restricted to a single method of input: direct touch. But with resistive devices, users may control the device via direct touch, gloves, stylus and more. Because capacitive devices work by identifying the electrical charge produced by the operator, there must be a direct touch in order for the command to register. Although it requires direct touch to function, capacitive touchscreen devices support multi-touch controls.
Capacitive touchscreens were actually invented almost 10 years before the first resistive touchscreen. Nevertheless, today's capacitive touchscreens are highly accurate and respond instantly when lightly touched by a human finger. So how does it work? As opposed to the resistive touchscreen, which relies on the mechanical pressure made by the finger or stylus, the capacitive touchscreen makes use of the fact that the human body is naturally conductive.
Capacitive screens are made of a transparent, conductive materialusually ITOcoated onto a glass material. It's the glass material that you touch with your finger. In a surface capacitive setup, there are four electrodes placed at each corner of the touchscreen, which maintain a level voltage over the entire conductive layer. When your conductive finger comes in contact with any part of the screen, it initiates current flow between those electrodes and your finger.
Sensors positioned under the screen sense the change in voltage, and the location of that change. In a device that uses a projected capacitive setup, transparent electrodes are placed along the protective glass coating in a matrix formation. One line of electrodes vertical maintain a constant level of current when the screen isn't in use. Another line horizontal are triggered when your finger touches the screen and initiates current flow in that area of the screen. The matrix formation creates an electrostatic field where the two lines intersect.
This is one of the most sensitive types of touchscreens, and is how some phones can sense a finger touch even before you make contact with the screen itself. Projected capacitive technology also allows you to use the touchscreen even when you're wearing thin gloves. The choice to use a capacitive or resistive touchscreen depends largely on the application for the device. Most devices with resistive screens are used in manufacturing, ATMs and kiosks, and medical devices. Register fewer inadvertent touches: In many cases, users might prefer a capacitive touchscreen over a resistive screen for its responsiveness and sensitivity.
Yet, there are instances where users might not want a high-sensitivity display. Users might prefer a resistive touchscreen when inadvertent touches on the screen are anticipated — such as when liquids think rain fall on the touchscreen. A resistive touchscreen will not pick up light touches. Resistive has been the norm: Resistive technology has historically been the norm among rugged handhelds. Windows Mobile apps have been designed for resistive touchscreens, incorporating small icons that work well with a fine-tipped stylus, but not with a larger fingertip.
This major factor lead rugged handheld manufacturers to stick with resistive touchscreen technology. While software developers are designing apps that are capacitive touchscreen-friendly, we have provided an interim hold-to-zoom feature on the Archer 2. This feature accommodates for small icons and makes it easier to press them with your fingertip.
They are large and easy to access. Cheaper: Resistive touchscreens have been cheaper than capacitive touchscreens — another reason rugged handheld manufacturers stuck with resistive technology. However, capacitive touchscreens are becoming more prevalent and affordable. Durability: Generally, the display is the most vulnerable part of a handheld device.
One advantage of capacitive touchscreens is they tend to be more rugged than resistive touchscreens — especially under heavy use.
Heavy users may find frequently used areas on a resistive touchscreen wear down and become unresponsive. In particular, the touchscreen on the Archer 2 is especially rugged. Made with chemically strengthened glass, its touchscreen is incredibly resistant to scratches and other damage. The screen can shatter and continue to function. On the other hand, resistive touchscreens will often stop working if any part of the screen is damaged.
This is an important advantage of capacitive touchscreens because it allows a field worker to continue to collect data until they can get their screen repaired. With a resistive touchscreen, a field worker may have to forego further data collection until the screen is fixed. Future-proofed: The technology industry is leaning toward capacitive technology, but using a capacitive touchscreen on the Archer 2 will help ensure a smooth and compatible transition to future technologies.
Multi-touch capability: Capacitive touchscreens are better suited for multi-touch capability. This means they easily register more than one input at a time. Resistive touchscreens are extremely limited in this function.
