One of the major goals in the development of new types of technology finding ways to do things better. The term ‘better’ can mean a number of different things. ‘Better’ can mean cheaper, more efficient, bigger, smaller, more attractive to consumers, more durable, or lighter. But ideally it’s some combination of the above features. (Of course, having something be both bigger and smaller isn’t at all possible or desirable, but it is desirable for technology to be scalable to a number of different sizes for a number of different applications. One area in which technology has seen a lot of different changes over the past decade or so is with display technology. It used to be that the only type of screen that could be used for TV sets, computers, and other applications was the cathode ray tube. The cathode ray tube has a lot of advantages that include rich colors, quick response time, and low production cost. Cathode ray tubes also have a number of disadvantages including the fact that they’re bulky energy hogs that qualify as toxic waste when it comes time to dispose of them.

That said, there have been a number of different types of technology that have come along to replace the cathode ray tube, or at least function as an alternative to the bulky tubes. Most of us have heard of most of them: plasma screens, LCD displays, and digital light processing (DLP). These all have their own advantages and disadvantages. For example, plasma screens and LCD displays can be made in extremely thin panels that really reduce the bulk of a TV screen. But Plasma screens also hog energy and have a limited life expectancy, while LCD screens tend to blur and don’t have very good contrast ratios. DLP screens have quick response times, but hog energy because of the requirement of powerful light sources. It’s also debatable whether or not any of these technologies are any more environmentally friendly than the old fashioned cathode ray tube when it comes to disposal or production.

Now their’s a new display technology that’s gradually being developed and released in consumer goods that provides a lot of advantages over these others. It’s called organic light emitting diode technology or OLED for short. This new display technology takes advantage of placing organic substances that emit light in the screen itself. This in itself has a number of advantages. For example it eliminates the need for back-lighting, resulting in a significantly thinner display panel than is possible with LCD technology. (LCD technology requires room for fluorescent lights for back-lighting.)

OLED technology also gets around many of the other drawbacks of LCD technology. For one thing, OLED technology has a fraction of the response time of even the best LCD screens, which eliminates blurring as far as the human eye can see. It’s also highly efficient, and since it doesn’t have a source of back-lighting that has to be blacked out in order to produce black, it has ten times the contrast ratio that LCD screens are capable of.

While OLED screens still have to jump through a few hoops to prove themselves, they show a lot of promise as improvements on older technologies.
