How To Select the Optimum Touchscreen Technology For Your Organization

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?

Resistive Touchscreen 

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.

Capacitive Touchscreen

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.

Laser Cutting vs. Die-Cutting

Nameplates & Dials, Overlays, Panels

If you are in the nameplate business, you have probably heard the terms laser cutting or die-cutting before, but do you know when one cutting technology should be utilized over the other? Each method of cutting possesses its own set of advantages depending on the project.

Laser Cutting

Laser cutting is a form of cutting that utilizes a CO2 laser as a cost-effective alternative to steel rule die-cutting. Due to the narrowness of the laser beam, cutting with a laser can provide improved precision, and is a good choice to use for projects that require small and/or detailed cuts. The laser cuts all the way through the material, dropping out all internal cuts. Another benefit of laser cutting is the fact that the zone affected by heat is quite small compared to using die-cutting, which decreases the chance of the material warping where it is being cut.

Die-Cutting

Die-cutting requires die tooling which consists of cutting blades embedded in a wooden base surrounded by rubber cushions. Outside shapes and interior holes can then be die-cut in a single stroke. Hard tools (also known as Class A Tools) perform the same process; however they are made out of a harder steel and consist of both male and female tools. This results in a tighter tolerance and an extended tool life that can last millions of strikes before needing to be replaced. One area where die-cutting outperforms laser cutting is the quantity and speed at which it can cut materials. Since a die is able to cut multiple areas in a single stroke, it is able to perform at a much faster rate than a laser cutting machine.

While each form of cutting has its own list of pros and cons, ultimately the one you decide to go with depends on the specific product being cut. Always make sure to ask your manufacturer for their recommendation, and if cost is a factor be sure to take initial tooling charges into account when making your decision.

Designing a Touchscreen: Where to Begin

Touchscreens are gaining popularity with manufacturers as an alternative to other switching technologies, and it is easy to see why. When it comes to user interfaces, touchscreens have successfully changed the way electronic equipment is used by simplifying the user experience and eliminating the need for buttons or keys. If you are considering incorporating a touchscreen into the design of your product, there are key items that you should consider.

First you should understand the difference between a resistive touchscreen and a capacitive touchscreen.

Resistive TouchscreenResistive Touchscreen Illustration

A resistive touchscreen is constructed using two clear conductive layers (typically a glass or acrylic substrate and a polyester top sheet) that are separated by insulating dots. When the user touches the screen and compresses the top flexible layer, electrical contact occurs between the top and bottom layer.

Capacitive TouchscreenCapacitive Touchscreen IllustrationRGB

Voltage is applied to the corners of a capacitive touchscreen and distributed by a pattern of electrodes located around the touchscreen periphery. This creates a uniform electric field across the conductive surface. When the user touches the screen with a conductive object (such as their finger), they are drawing a minute amount of current from the surface. This change in capacitance is measured at each point on the touchscreen allowing the touch position to be located.

Before you actually sit down and design your touchscreen, there are at least four main considerations you need to take into account:

  1. Environmental conditions
  2. Software requirements
  3. Firmware requirements
  4. Appearance

These will help you determine the materials and types of technology to utilize in your touchscreen. For each consideration there are a number of questions you will need to ask yourself:

Let’s Explore the Possibilities

Think of every time you have purchased something in a dimly lit area. Maybe it was having a drink with a colleague during happy hour, or perhaps grabbing a bag of popcorn and a drink at the cinema concession stand before going to see the latest blockbuster? Possibly you hit the jackpot while playing slots at the casino? Every time the lights are low is a time for your product to shine. The possibilities are endless.

Monster Game Full Shot Smaller

Speaking of endless possibilities: why limit illumination to dimly lit spaces? Creative lighting could also be used to feature cosmetics and fragrances. Imagine walking into a space that feels clean and crisp. Using bright white LEDs under white acrylic with custom trim will make your product look flawless. Illumination can be used to highlight the characteristics of your product that you want customers to notice most, or it can be used to set the overall tone and feel of your unique brand. This can be accomplished by creating backlit signage, glorifiers, or something completely different that hasn’t yet been thought of.

Backlit signage can be created with very intricate detailing by using digital, screen, and litho printing techniques. This especially becomes important if your sign requires thin font types. Advanced printing technology & attention to detail is required to create sharp lines within the signage to create well-defined edges between colors.

Printed Electronics: Endless Possibilities for Innovation

Have you ever stopped to think about how many times you use something electronic in a day? Electronics have become a staple in people’s lives all over the globe, allowing us to communicate instantly with one another, make purchases online or in a store, and even get from Point A to Point B.

A great deal of engineering & design work can go into making these electronics, as well as complicated manufacturing processes. Thanks to advances in technology electronics are getting easier and cheaper to manufacture. One of the most efficient new manufacturing methods is the ability to print an entire electrical device on various substrates, a process resulting in Printed Electronics. Before we get into how these flexible devices can benefit you & your company, let’s first explain how they work.

What are Printed Electronics?

Various printing methods can be used to deposit electrically functional & optical inks onto a substrate. The inks can be deposited in any pattern to suit the type of application it is being made for. The result is a fully functional electronic device that can be thin & flexible, or more durable depending on what it’s for. Widths of traces can vary from super fine to broad.

Materials used for printed electronics can include polyester, polycarbonate, polyimide, and FR-4. Substrates can then be coated to protect the printed pattern. Top-performing inks, coatings, & plating include:

  • Silver
  • Copper
  • Aluminum
  • Nickel
  • Gold
  • Silver/Carbon

The printed electronic devices can then be molded, cut (laser or die), or formed into any required shape.
