The Evolution Of Electronics Display Technologies Explained
Published by Fred at March 3rd, 2010Electronics have evolved quite a bit since the 1980’s, when electronics displays really started to make their mark on the world. It’s interesting to see the hardware and electronics behind each evolution, as we can use it to better understand where the industry came from and where it’s going.
When you use a simple calculator, you might notice that the display you are using is very basic. This display is a liquid crystal display, or LCD display. It comes in many forms, as you will see the same technologies present in current computer monitors. LCD technology has been around for many years and continues to evolve itself as a technology product.
The expensive high definition televisions that can be bought today are often using plasma as the display technology. Plasma is nothing new, believe it or not! Plasma was employed in older computer displays, but could only use one color due to limitations in technology back then. Plasma screens are much more advanced today, and are able to display millions of different hues and colors down to a single pixel.
As far as light efficiency goes, LED lights rank among the best in energy consumption. LED lights are used in practical applications for the most part since they are not as flexible as other display technologies. Often you will see LED lights in your computer as an indicator that your computer is on, for instance. LED lighting is making a huge stir in the home lighting sector as well, where consumers have found that these efficient lights also save money on energy bills.
CRT monitors are still very popular- especially among older folk. CRT monitors are referenced as cathode ray tube displays- something that is incredibly inexpensive in current markets but also very bulky. A 20-inch CRT monitor can easily weight as much as ten pounds or more, whereas current LCD monitors would weigh about half that. For that reason, CRT monitors have fallen out of favor. CRT monitors also do not support the level of resolution that newer types of monitors do.
It’s exciting to think of the new types of technologies that are emerging even now. New types of display technologies, such as the Apple iPad, make us rethink what an electronics display should be. Touch screens are playing a big part in future advances in electronics, and even more mind-blowing technologies are being developed as these are released. From outdated plasma displays to new touch screen technologies, the industry has come a long way.
In Conclusion
Displays will continue to evolve until we see something that can fit all needs. New displays will be more energy efficient, less expensive, support a wider range of functions, and give way to a more exciting time of innovation and inventions that will spur the technology industry completely.
