For anyone over the age of thirty, it is well known that electronics displays have changed drastically over the decades. The new display screens of today, that new generations enjoy, were not in existence even just ten years ago. It’s fun to see where the industry all got started by learning of past display technologies.

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.

Light emitting diode displays, known better as the LED, have also had their own separate evolution process. The LED display bloomed late in popularity, however. While the LED doesn’t have the color options and affordability of other technologies, it is extremely efficient when used in proper applications. An LED light, for instance, is much more energy efficient than your average light bulb currently in use by the average United States family.

The cathode ray tube, or CRT, is what fueled much of the evolution of computer displays and television displays. The CRT allowed for great resolution, it was affordable, and it could support a very wide range of colors seemingly in an instant. Even today, the CRT monitor is still in use since they are so inexpensive and can often be found second-hand at garage sales. They may be more bulky than newer technologies, but they work just the same for the average user.

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 From outdated plasma displays to new touch screen technologies, the industry has come a long way.

Closing Comments

The displays of the past are important to learn, so that we know where the electronics industry originated from. New technologies are often based or compared to these technologies, so they are also used as a meter stick in order to gauge the worth of new innovations in electronics displays.
