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.

Recent energy-efficient movements have made the LED quite popular. The light-emitting diode is a display that is incredibly energy efficient, but is limited in what it can be used for. The average LED is used in basic light operations- perhaps for an electronic banner or for a light bulb. LED lights are only recently becoming popular with consumers, who like the energy they save and enjoy the longer life span that the lights have as a result of being more efficient.

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.

At this point, the industry is looking more at innovation than a way to make current technologies smaller and more efficient. Focus has been put on technologies such as touch capability- which has exploded into the retail market. It has also been used dominantly in the mobile phone market, that has been able to create many innovative mobile phone designs as a result of trends in touch screen displays.

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.
