Backlights are used in a wide range of applications in which illumination is needed. This typically includes televisions, computer monitors, keypads, keyboards and similar applications. Up until 2010, however, cold cathode fluorescent lamp (CCFL) has been the preferred backlighting technology for liquid-crystal displays (LCDs). Today, light-emitting diode (LED) is the industry’s leading backlighting technology. There
Not to be confused with user interfaces, human machine interfaces (HMI) are complex control systems that allow a human operator to control, manage and monitor the processes of a machine or system. Manufacturing companies, for instance, often use HMIs to control the operations of robotic assembly lines. A typical HMI features data regarding the system’s

Benefits of UV-Coated Keypads

Are you looking for a new keypad solution? If so, you should consider choosing an ultraviolet (UV)-coated keypad. It features the same functionality as a traditional keypad but with a few added benefits. To learn more about UV-coated keypads and the benefits they offer, keep reading. Overview of UV-Coated Keypads UV-coated keypads are designed with

Silicone Rubber Keypad Guide

If you’re searching for a new keypad, you should consider silicone rubber. Also known as elastomeric keypads, they are used in a wide variety of applications, including both consumer and industrial applications. To learn more about silicone rubber keypads and the benefits they offer, keep reading. Overview of Silicone Rubber Keypads Silicone rubber keypads live
Not all keyboards fall under the category of flat-panel membrane or mechanical-switch. There’s also a hybrid type that combines elements from both. Known dome-switch, it uses two circuit board traces under a flexible keypad using either metal or polyurethane formed domes (hence the name). To learn more about dome-switch keyboards and whether or not they
Whether it’s a human machine interface (HMI), television, calculator or any other liquid crystal display (LCD) device, all LCDs use backlights. LCDs themselves do not produce light. This is in stark contrast to cathode ray tube (CRT) displays, which do produce light. And because of this, they require a separate component to illuminate the panel
Resistive touchscreen technology is often preferred over capacitive because it supports the use of both bare and gloves fingers. This is in stark contrast to capacitive, which only detects the presence of a bare finger. Since resistive touchscreen devices identify touch by pressure instead of change in capacitance, however, they can be used with a
More and more manufacturing companies are investing in human machine interfaces (HMIs). As the name suggests, an HMI is an interface through which a human operator controls a machine. Manufacturing companies typically use them to control various machines and systems. To learn more about HMIs and how they are used in the manufacturing industry, keep
Not all touchscreen devices use capacitive or resistive technology. While these are the two most popular types of touch-sensing technology, there are others available, including infrared (IR). So, what is an IR touchscreen exactly, and how does it work? Overview of Infrared Touchscreen Technology IR touchscreen devices support touch-based input just like any other touchscreen
When choosing a keypad, one of the decisions you’ll have to make is whether to choose a membrane or mechanical model. There are dozens of different keypads available, though most fall under one of these categories. So, which one is right for you? Overview of Mechanical Keypads Mechanical keypads are traditional keypads that provide a
