LED Television: The Next Generation In Flat Screen Technology
The battle between plasma and LCD televisions was won some time ago by LCD of course; providing a comparable picture, at a lower cost, with lower energy consumption and with greater longevity. Job done you would have though then. But things are never that simple, and now we have the LED television to consider.
It is not at all surprising that this change is driven by the major players in the electronics, and most certainly monitor and TV screen industry. However, a quick look at the new technology demonstrates that they are certainly a step forward; rather than simply be a way to get the consumer to part with more cash.
To appreciate this however, it is necessary to understand where LED television technology differs from what has gone before. In the most basic of levels, LED technology is simply a progression from LCD; it uses the self same screens for a start; and works in much the same the way. The difference lies in how light is sent to the screen; with LEDs, this is done through backlighting or side lighting.
Having the lights set up in this way allows for greater control of the picture; lights can be dimmed and brightened independently of their neighbours; creating a richer content and feel and most important of all, creating true image black scale; they key to picture quality.
This is all fantastic of course, but what are the downsides to LED television technology? Increased power? Short Lifespan? Surprisingly, the opposite of each of these is true. The technology use less energy and, just as importantly uses this energy well with minimal wastage, which in itself drives up how long the TV itself will last for. Indeed, estimates suggest they could go on indefinitely if looked after well.
They are also a great deal thinner than there predecessors. Whilst regular LCD TVs are very slim; at just mere inches, an LED television will be measured with a depth given in millimetres. Indeed, the leading manufacturers are producing units that are a mere 6mm in depth.
Okay, this all sounds excellent but of course, it isn’t all good news. Whilst no limitations exist to the operation of an LED television, there is a limitation regards affordability. It is really no different to the large prices that LCD and most particularly plasmas were tagged with though.
The benefits then are quite significant with this new technology; better pictures, better lighting; better control, and all whilst having a positive impact on the environment. Indeed, the only downside remains the price.
The good news for LED television detractors then is that the prices will inevitably fall; and the benefits will still be there, (and probably improved upon even more). However, it is also likely that new technologies will just about be ready to launch by this point, as the wheels of progress continue to turn.
