Capacitive switches have become a popular alternative to mechanical switches. As their name suggests, they leverage capacitance. Capacitive switches measure changes in capacitance, and they use this information to open or close a circuit. Pressing a capacitive switch...
Frequently Asked Questions About SAW Touchscreens
There are other types of touchscreens besides capacitive and resistive. An alternative technology, for instance, is surface acoustic wave (SAW). SAW touchscreens support touch commands just like their capacitive and resistive counterparts. They are unique, however,...
How Liquid Crystal Displays (LCDs) Are Wired
Liquid crystal displays (LCDs) require wiring. All LCDs feature a pixel layer consisting of a liquid organic material. Depending on the resolution, it may have 6 million or more individual pixels. LCDs leverage these pixels to produce images. They must be wired,...
How to Choose Touchscreen Gloves
Do you own a capacitive touchscreen? Capacitive touchscreens are undoubtedly popular. When compared to resistive touchscreens, they are more responsive, longer-lasting and produce higher-quality images. Unfortunately, they don't support the use of regular gloves....
Why LCDs Have Two Polarized Layers
Liquid-crystal displays (LCDs) contain many different layers. They feature a pixel layer, for instance, that contains the liquid pixels. They also feature a backlighting layer that's responsible for illuminating the liquid pixels. LCDs, however, also feature two...
Pros and Cons of Vertical Alignment (VA) LCDs
Have you heard of vertical alignment (VA)? It's become one of the most popular types of liquid-crystal display (LCD) technologies on the market. You can find TVs, computer monitors, tablets and other display devices that feature a VA LCD. If you're thinking about...
What Is a Hall Effect Keyboard?
Have you heard of hall effect keyboard? If so, you might be wondering how they differ from other types of keyboards. All keyboards consist of switches. Each key is essentially a switch. Pressing a key will close the underlying circuit. Releasing a key will then open...
