Electronics 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.
The liquid crystal display, or LCD, has been around for decades. Even in the 1970’s, there were innovative electronics devices that made use of monochrome colors to display basic data. As the industry was still relatively new to the consumer market, most of the displays were only put into the likes of calculators and other basic objects.
The high end televisions of today use plasma technology. It’s funny to think that this technology was one of the first innovations in display technologies- and was around back when computers could only display one color! The technology may not have been as advanced back then, as the computers that used them might only display the color green or orange. Today plasma screens can use millions of different colors.
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.
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.
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.
Final Thoughts
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.
