Modern Display Technology Has Come A Long Way Lately
For anyone who has plopped themselves down in front of the latest liquid crystal display TV, the quality of the picture being displayed can truly be astounding. It’s certainly the case that modern display technology has come a long way lately, especially when it comes to extremely tiny LCD screens that can be found, for example, in certain expensive automobiles or even in modern aircraft. CRT tubes and big, fat televisions have definitely left the scene, it seems.
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.
Whether these display screens are used in televisions or as part of another application, just about all of them use much less energy than typical display screen lighting technology is capable of producing. This is especially the case with LCD TVs and other display modules that take advantage of light emitting diodes. All use a great deal less energy, and are seen in everything from aircraft cockpits to medical equipment.
A relative to the custom liquid crystal display module is the graphic LCD unit. It interfaces extremely easily with most computers through use of a common USB 2.0 port or through an older style serial port connection. Just about all of them can be easily programmed to display a wide variety of data and information and normally cost somewhere around $100 for a unit that can carry out a great deal of functions.
Innovation is a fact of human existence. A lot of good work has been carried out in taking the common LCD display screen and turning it into something that is much better than it was when it first made its appearance in common wristwatches many years ago. As far as widespread consumer applications, the flat-panel LCD TV is probably best known, and the work that’s gone into it has been impressive and has turned out a TV that’s miles ahead of its older cousins.
