Modern Display Technology Has Come A Long Way Lately

Improvements in LCD technology over the years has been steady and, lately, even spectacular. Liquid crystal display screens are popping up everywhere in greater proportions than ever before. These modern ways of displaying information have come a great distance, to the point where very tiny LCD screens can be found in very common consumer electronics or in the most modern automobiles and aircraft. It would seem that the CRT tube and heavyweight TVs are going the way of the dinosaur.

As an example, consider some of the most popular LCD televisions these days. Some of the display screens and television casings are matched together to produce a TV that’s only about a half-inch in thickness. This is made possible by LED backlight technology, which is rapidly replacing more traditional fluorescent tube backlighting for an LCD television’s display screen. It also has made the TV extremely thin.

These light emitting diodes run along the edges of a typical LCD TVs display screen, hidden behind what’s called a ‘bezel, ‘ helping to brighten and sharpen the display in very useful ways. This is a classic example of how innovation and technology is used to improve a common consumer good like a modern LCD TV to the point where it is stunningly slim in its appearance.

This actually isn’t the only innovation that has begun to benefit display screens of all sizes, by the way. Currently, some really small custom LCD screens have been produced that are being used in a variety of ways, including for data display modules such as can be found in an aircraft or even more expensive automobiles. They cost less than 100 bucks and can really add not only good looks but also are a definite improvement over analog gauges.

Considering that they also use far less energy, on average, than older digital or analog gauges, it’s no wonder that custom liquid crystal display screens have made their way into aircraft cockpits or even personal automobiles and the like. This isn’t to mention how useful they’ve become in medical equipment applications as well as all manner of measuring tasks.

A sibling to the custom liquid crystal display is the graphic LCD module. Many of these small display units can interface easily with all manner of computer equipment through very handy USB or even serial port connections. All are capable of being programmed to display an extremely diverse amount of information and data and usually cost somewhere around $100 or thereabouts.

When it comes to innovation, it seems that some of the best work is being done in taking liquid crystal display technology — which actually has been around for decades — and improving it by leaps and bounds. The first big step for the LCD, when it came to consumer applications, was the flat-panel TV. Since then, a lot of work has gone into improving that display, and the televisions and other display technologies now available are a full order of magnitude better than units from just a few years ago.
