An OLED tv is a tv that uses organic carbon based compounds which emit red, green and blue light. There are two types – small molecule and polymer. Sony, the creators of the world’s first organic led tv, used the small molecule type due to its longer lifespan.

		The tv’s work by compressing a layer of organic materials between an anode and a cathode, which are in also sandwiched between two glass plates – a top plate (seal) and a bottom plate (substrate). The panel is then supported by hard plexiglass which protects the inner materials and allows the oled tv to be mounted with tv wall mounts. An electric current is then passed between the two conductors, producing bright electro-luminescent light directly from the organic material. An OLED tv differs from an LCD TV in that no backlight is required to energise the organic colour compounds and there’s no ‘twisting’ of crystals. The result is a display that can be made extremely thin and uses considerably less power, saving the user considerable amounts on their electricity bills. The screens excel in black levels and contrast, with the latest Sony television quoting a massive 1,000,000:1 contrast ratio (and no that’s not a typo) compared to the highest tv lcd of 10,000:1. Since the tv’s don’t have a backlight, they don’t have to block light out when not required and also produce black levels never seen before.

The displays also have superior picture quality with deeper and more lifelike colours, with a colour gamut exceeding that of NTSC standards and as with an organic led tv every light is lit independently, they create light rather than blocking it as an lcd would. This means they can support almost perfect viewing angles up to 170 degrees!

The displays also dramatically enhance the viewing experience, coping with action and sports programmes better than any other tv and providing sharper frames that really pop out of the picture with refresh rates up to one thousand times that of an LCD.

In theory as an OLED requires very little power to operate, it should last for an extremely long time. However, the blue organic phosphor used has a short life of around 7,000 hours (yet to be tested) and the red and green may not last much longer. Time will tell and we’ll have to see how the first prototypes cope over the next few years.

The panels may also be at risk from screen burn due to the organic material being used. Again, time will tell but the effect is not expected to be as dramatic as plasmas.

OLED’s are still quite small in size as they’re new to the market, but have the potential to become huge – just image a 9 foot wide tv in the middle of your living room! With all this promise there’s no doubt that OLED will be leading tv technology for years to come, so stay tuned!

Sadly a cracked tv screen is not an easy fix and will need to be totally replaced, the cost of which can be almost as high as the tv itself. Retailer warranties generally don’t include accidental screen damage, so make sure you know the extent of the cover or your tv, and your wallet, may in danger.

So how do you prevent your display from being damaged? The answer is a screen protector, and there’s a great range now available.

Screen protectors are used to guard a wide range of displays from damage, from personal use to reinforced versions for public sector hospitals, corporations, and even the US military.

The protectors tend to be simple to use, light-weight pieces of high grade acrylic that hangs over the top of your display. They often require little to no assembly and are secured with straps around the back of your tv led. Many also include rubber grips to keep the screen in place and small felt spacers to absorb impacts and prevent the screen scratching the display.

Some protectors also come with more advanced features including non-glare optical grade plastic ensuring clarity and sharp, clear, and vivid high definition viewing. Others are even known to block very low levels of harmful UV light from plasma and LCD televisions, with one brand quoting their screens as blocking up to 92% of all Ultra Violet light in the UVA/UVB and some of the UVC spectrums (250nm to 400nm).

Of course, occasional cleaning of the screen protector will be necessary, but they’re much easier to clean than LED TV displays as they can be sprayed on and pressed down, and are likely to need cleaning less often that you do currently.

The only disadvantage to a screen protector may be that they do tend to reduce a tv screens brightness by about 5%, but that can be easily remedied by turning up the brightness up to accommodate.

For the personal consumer they’re available from around 19 inches to 55 inches diagonally and are available from a number of international retailers. Compared to the value of the tv the price of the screens is quite low at around £40 ($60) to almost £100 ($160) for the really big ones.

For the business consumer, complete screen enclosures are available for screens up to 65 inches, where the entire LCD TV is encased in strong aluminium extrusion and acrylic and hung using tv wall mounts. The enclosures are available in two colours; a black anodized frame with black matte acrylic, or a silver anodized frame with a frosted acrylic.

The enclosures also include air vents and guarded dual fans to keep the display cool, high quality sound option upgrades, and tamper proof screws.

As with any internet purchase, make sure you research your purchase beforehand and err on the side of quality rather than cost as the screen will be an investment for the future. Make the right choice and ensure you find a product that will protect your display for years to come.

Many of the new TV’s out there go by the name LED TV, but they’re actually not an LED TV as such – they’re actually an TV LCD with an LED backlight, and can cost almost twice as much as their LCD TV or plasma TV counterparts.

So why have a LCD TV with an LED backlight? Until now LCD TV’s used florescent tubes to light the screen. As these tubes are always on, some light would always leak through and so the TV had trouble producing deep blacks, which affected the perceived sharpness. The tubes also lacked a wide range of colours, meaning the colour saturation of the image could be limited.

An LED TV uses light emitting diode’s to illuminate the display by mounting tiny lights in rows either behind the display or around the edge of the display (known as ‘edge-lit’ displays).

It’s difficult to say which method is better as both have their own pros and cons. Edge-lit LED TV’s can be made ultra thin as the LED’s are on the side of the display. As they have fewer light emitting diodes in them they’re also less expensive than their backlit alternatives.

Backlit displays on the other hand can create deeper blacks by using ‘local dimming’, shutting off LED’s in dark areas of the image and preventing unwanted light shining through. Of course, these additional LED’s come at a price as backlit LED’s tend to be more expensive.

So backlit is better, right? Well not necessarily. The additional LED’s on backlit tv’s can’t be shut off individually and needed to be shut off in larger groups. This means that light areas that are next to dark areas can be darkened when they should stay light. The opposite is true too – by counteracting this darkening affect by lightening the image can cause blacks to be lighter in areas surrounded by lighter images.

A tv screen with every LED lit separately would be a true LED TV which, while possible, would be very expensive and currently only used for very large billboards.

But some there are some clear advantages of LED TV’s over LCD TV’s and plasmas. LED TV’s use less power than their LCD or plasma counterparts and do not use mercury, so are better for the environment. They also have more balanced colour contrast and stronger colours, making images sharper and more vivid.

At the end of the day the choice is really up to you and as with any big purchase it’s important to research it fully before you buy. Take a visit to your local retailer and compare the different tv’s against your budget. Make sure you choose one you loved watching and that meets your requirements – and once you’ve got it go home and enjoy it!

The most common type of ‘liquid’ crystal used in LCD TVs is twisted nematic – a naturally twisted crystal that reacts to electric currents by untwisting to various extents according to the voltage being passed through it.

By pressing this crystal between parallel panes of polarized glass, it’s possible to manipulate the intensity of light that passes through it, and change the display from light states (where the crystals are fully twisted) to dark states (where the crystals are fully untwisted), and grey states in-between.

A TV LCD display such as a Samsung LCD TV then, consists of thousands of arrays of tiny crystals called ‘pixels’, that are manipulated together to form images on the screen. The process of manipulating these crystals is called ‘addressing’, where each pixel is individually turned on or off to create a image for the viewer.

The light for the TV LCD is created with an array of florescent bulbs or (more recently) LED’s (light emitting diodes) that emit light through the polarized glass behind the liquid crystal, backlighting the display. As the crystals allow all wavelengths of light to pass through, the full spectrum of colour can be harnessed and manipulated to create the images required.

To display different colours, each pixel is divided into three sub-pixels – red, green and blue – that work together to achieve the hue. With each sub-pixel able to create up to 256 colours, the use of all three sub-pixels means a single pixel can produce up to an amazing 16.8 million colours – amazing!

So why choose a TV LCD?

With each pixel on an LCD display having it’s own transistor electrode, TV LCD’s can feature smooth, wide, saturated and evenly lit images with none of the lines that older projection TV’s used to suffer from, even on a 32 inch lcd tv or larger.

With all that light and so many pixels, it’s no surprise then that flat panel TV LCD displays also tend to be significantly brighter and have higher contrast ratios than the older CRT displays. This means that a TV LCD won’t wash out in brightly lit rooms, glare under direct light, or flicker, which can cause eye strain.

TV LCD’s also support wide viewing angles of up to 160°, allowing the display to be viewed from almost anywhere in the room. They’re also significantly thinner than older projection TV’s, allowing them to be mounted wherever they’re needed using tv wall mounts.

And last but not least, the average lifespan of a tv lcd display is around 60,000 hours – that 2500 days of constant watching or almost 7 years – so find some good lcd tv deals online and get yourself one!
