Liquid-crystal displays (LCDs) are undoubtedly popular. They are used in countless consumer and commercial display applications. Aside from being popular, though, LCDs offer other benefits. Here are six benefits of LCDs, some of which may surprise you.
#1) No Refresh Rate Flicker
LCDs typically suffer from refresh rate flicker. Also known as screen flicker, refresh rate flicker is a phenomenon in which a display appears to “flicker” when changing frames. The pixels in LCDs retain their state during these frame changes, so LCDs are naturally protected against refresh rate flicker.
#2) Supports All Shapes
When most people think of LCDs, they envision rectangular-shaped TVs and computer monitors. Most LCDs are, in fact, rectangular. Nonetheless, you can find them in many other shapes. LCDs support all shapes. This is why smart wearables often feature LCD technologies. Smartwatches and other smart wearables may feature unique shapes, making LCD the ideal display technology for them.
#3) Produce Less Heat Other Display Technologies
Heat is a byproduct of all display technologies. To produce visible images, display devices must consume energy. They will inevitably generate heat as a byproduct of the consumption of energy. Fortunately, LCDs produce less heat than other display technologies. This is because they are energy efficient. LCDs consume less energy and, thus, produce less heat than other display technologies.
#4) Little or No Electromagnetic Radiation
Another benefit of LCDs is that they produce little or no electromagnetic radiation. It’s not uncommon for other displays to produce electromagnetic radiation. Cathode-ray tube (CRT) displays, for instance, produce a fair amount of electromagnetic radiation during use. LCDs, on the other hand, do not. They produce almost no noticeable amount of electromagnetic radiation.
#5) Available in Passive- and Active-Matrix Styles
LCDs are available in passive-matrix and active-matrix styles. Passive-matrix and active-matrix LCDs both use liquid pixels and backlighting to produce images. The difference lies in their construction. Passive-Matrix LCDs are constructed with a grid that applies a voltage to the pixels. Active-matrix LCDs are constricted with transistors and capacitors. The transistors and capacitors are able to hold a charge for a given period.
#6) Low Operational Cost
LCDs have a low operational cost. All displays consume energy during use. Energy, of course, costs money. LCDs, though, only consume about one-quarter of the energy of their CRT counterparts, which is responsible for their low operational cost. Because they cost less to use, LCDs are popular among consumers and businesses alike.
