5 Things to Consider When Choosing a Resistive Touchscreen
Resistive touchscreens are a popular alternative to capacitive touchscreens. They are able to detect and respond to touch commands -- just like all touchscreens. Resistive touchscreens, however, feature a unique design consisting of multiple electrically resistive...
How to Choose Light Guides: What You Should Know
For better light distribution -- as well as increased energy efficiency -- you should consider adding light guides to your device. Light guides are commonly used with keypads, switches, dome arrays, human machine interfaces (HMIs) and other devices. They are designed...
What Are Light-Emitting Diode (LED) Keyboards?
When researching keyboard technologies, you may come across light-emitting diode (LED). LED keyboards are built into many laptops, and they are sold separately as external peripherals. While available in the same key layouts as other keyboards, LED keyboards stan out...
5 Facts About OLEDs You Probably Didn’t Know
Organic light-emitting diode (OLED) has become a popular display technology. Most modern-day displays, in fact, now use either OLED or light-crystal display (LCD) technology. Also known as organic electroluminescent diode, OLED involves the use of an...
Frequently Asked Questions About Capacitive Switches
Switches are commonly used to control devices. A switch, of course, is an electrical component that can complete or break a circuit. While all switches are essentially controllable circuits, they are available in different types. In addition to mechanical switches,...
What’s the Best Backlighting for LCDs?
You can't choose a liquid-crystal display (LCD) without considering the backlighting. All LCDs require backlighting. The liquid pixels within them aren't electroluminescent, so they can't illuminate themselves. Instead, the liquid pixels require external illumination....
The Mechanics of SAW Touchscreens
Touchscreens have evolved over the years. In the past, nearly all touchscreens used one of two different technologies to detect touch commands: resistive or capacitive. While neither of these technologies has become obsolete, there are now other technologies...
Technology tips worth knowing
What Is a Super-Twisted Nematic (STN) Display?
Have you come across a display device that uses super-twisted nematic (STN) technology? If so, you might be wondering how it works. STN displays are capable of producing images just like all other displays. With STN technology, though, they offer some unique benefits....
What Is Temporal Performance in LCDs?
When researching specifications for liquid-crystal displays (LCDs), you may come across temporal performance. All LCDs have a temporal performance rate. Also known as the refresh rate, it plays an important role in the overall quality of an LCD's images. Temporal...
The End of Cathode-Ray Tube (CRT) Displays
It wasn't long ago when cathode-ray tube (CRT) dominated the display market. In the past, most displays -- televisions, computer monitors, etc. -- used CRT technology. CRT, in fact, has become synonymous with old-style displays. Like many other display technologies,...
5 Reasons to Choose a PCAP Touchscreen
Also known as PCAT, projected capacitive (PCAP) touchscreens have become increasingly popular. Like other capacitive touchscreens, they recognize touch commands by measuring capacitance. Touching the display interface causes a reduction in capacitance, which the...
What Is a Micro LED Display?
You've probably heard of light-emitting diode (LED) displays. In recent years, they've become one of the most popular types of electronic displays on the market. There are several different types of LED displays, however, one of which is micro. So, what is a micro LED...
Is a Touchscreen MacBook on the Way?
Ever since Apple released the first-generation MacBook over a decade ago, the Cupertino company has been reluctant to use touchscreen technology. Rather, Apple's long-running line of iOS-powered laptops have relied on traditional input methods, such as a keyboard and...
