The use of touchscreen technology is booming in this day and age, and for good reason. Companies across a broad spectrum of industries have successfully harnessed the power of touch for a wide variety of implementations after having realized the value touchscreens could bring to employees and customers alike. Touchscreens can allow for better customer service, thus producing an influx in sales, as well as provide a surge in productivity by employees controlling an industrial process.
If you are considering implementing touchscreens within your company, you must first determine the differences between the two types, resistive and capacitive. Due to the manner and conditions in which the touchscreen will be utilized, you will want to identify which form of the device will better suit your needs. So how do resistive and capacitive touchscreens differ?
The resistive touchscreen is the prevalent form of touchscreen, and, as the name indicates, it relies on resistance to work. It is constructed using two clear layers, such as glass or acrylic substrate, separated by a thin gap. The inside of these two layers are coated in a conductive material, so when the two layers are pressed together, a voltage is passed between them, which produces an accurate measure of where the touch was made on the screen.
Surprisingly, capacitive touchscreens were developed prior to the resistive touchscreen. A capacitive touchscreen consists of two spaced layers as well, also coated with a conductor. Voltage is applied to the corners of a capacitive touchscreen and distributed by a pattern of electrodes located around the touchscreen’s perimeter, which creates a uniform electric field across the conductive surface. When a conductive object, such as a finger, makes contact with the screen, a small amount of current is drawn from the surface changing the capacitance and allowing for the touch to be registered in that precise location.
So why is it important to know the difference between resistive and capacitive touchscreens? Well, it is due to the fact that the differences in how they work create variances in how they perform and in what manner they must be used in order to work properly. Depending on the differing situations and environments where the touchscreen will operate, one type may be the better option over the other.
So let’s reflect on the distinction between resistive as well as capacitive touchscreens in order to uncover which of the two types may ultimately be the most advantageous for you and your business.
Reasons one may prefer Resistive to Capacitive:
- Resistive touchscreen technology is more affordable than that of the capacitive touchscreen alternative
- Resistive touchscreens have higher resolution (4096 x 4096 DPI or higher), providing more accurate touch control
- Unlike capacitive touchscreens, resistive touchscreen technology can detect a touch by fingers as well as other non-conductive materials such as a stylus or gloved fingers
- Resistive touchscreens provide higher resistance to water and dust
- Resistive touchscreens are not affected by Electromagnetic Interference, whereas capacitive touchscreens are susceptible to EMI
- Due to the fact that capacitive touchscreens are made with a glass panel, they are more likely to require an anti-glare or an anti-reflective coating than a resistive screen if it is to be used in a brightly lit area
- Resistive touchscreens are the better suited technology for handwriting recognition than the capacitive option
Reasons one may choose the Capacitive option to the Resistive:
- No physical pressure is required when using capacitive touchscreen technology
- Capacitive touchscreens are more responsive to touch than a resistive screen
- Capactive touchscreens support multi-touch
- Capacitive touchscreens are easier to clean
- Capacitive touchscreens provide higher resistance to scratches and impacts and, overall, tend to be more durable than its resistive counterpart
- About 90% of light is transmitted from the display monitor of a capacitive touchscreen, causing better contrast and clarity than resistive touchscreens, which transmit only 75% of light from the display monitor
- The display on a capacitive touchscreen looks brighter and sharper than the resistive option since the capacitive monitors use a layer of glass rather than plastic
- Capacitive touchscreens do not require occasional recalibration which is necessary for some resistive touchscreens
All in all, you will find that either type of touchscreen enhances and simplifies the user experience, but knowing the difference in the two versions will allow you to determine which is best suited for your particular application. In doing so, you are sure to come away with the touchscreen that will optimize capability as well as productivity when in use.
As might be expected, even when keeping all of the factors which we just covered in mind, there are still other concerns that may come into play when considering your distinct touchscreen needs. With the numerous ways that touchscreens can play a role in day-to-day tasks, it is always in your best interest to consult with your manufacturer for proposals and solutions to the challenges that you may specifically face with touchscreen utilization. Together, we are likely to come up with an appropriate custom touchscreen design to maximize efficiency, affordability, and effectiveness for you.
