Picture it… The year is 1951 and a large family eagerly gather around a small black and white screen that gives a look into a world they have never seen. For the decades thereafter the television was the definition of entertainment with many people planning their lives around viewing their favourite shows. At the click of a button, this box of colour and sound allowed them to travel to the North Pole, watch men walk on the moon, keep tabs on world events and enjoy stories played out, right in their living rooms. Many years have passed now and the television has evolved, with new technologies emerging at a rapid rate. Let’s take a walk through the various types of television technologies.
How TV’s have changed
The early televisions were sizable in depth and weight due to the use of Cathode Ray Tube (CRT) technology which was favoured for much of the 20th century. Although now viewed as old-school, this technology was in fact a remarkable breakthrough that made home television possible.
Plasma and LCD
In the late 1990’s flat screen television made its debut and was so well received because it is lighter, thinner and bigger and lounge space is freed up as they can be mounted discreetly on the wall. Initially the battle was on between two flat-panel technologies, Plasma and LCD, but LCD TV’s were favoured because they are more energy efficient.
Recently, LED LCD screens have gained popularity. This technology is similar to LCD but Light Emitting Diodes are used rather than the old CCFL lamps. Two variations exist, one is edge-lit with the LEDs around the edge of the screen which allows the screen to be thinner, while backlit LED’s have a panel of lamps across the back giving a more consistent picture.
These televisions have a much higher resolution giving a super-sharp image that is more colourful and finer details can be seen. Ultra HD or 4K refers to sets with a minimum resolution of 3840 x 2160 for blur-free images.
Organic Light Emitting Diode (OLED) technology is a variation on LED but without the backlighting and each pixel lights up individually giving impressively fast response times for action shots. These televisions can also be very flexible, giving the possibility of curved screens and ones that roll up!
High Dynamic Range (HDR) is currently being marketed as the next big step in image technology that gives more natural, true-to-life colours and preserves contrast. However, both the television and the content played have to be mastered for HDR quality viewing.
A few years ago 3D television entered the scene but despite marketing efforts it has not gained popularity. Special 3D glasses are needed and you have to sit in the right spot to get the full benefit. But, there are now rumours of virtual reality television coming onto the scene and we watch with interest.
Today, all our devices must have internet connectivity and the television is certainly no different. Smart TV’s are able to access live streaming content, run entertainment apps and share content seamlessly between other home devices. These televisions can be used like large screen computers, making the possibilities endless.
With all these incredible options available few homes are without an impressive television but what do you do when your expensive TV gives trouble after the warranty is over? A large television is a sizable investment and, with our current economy, it is definitely worth looking at repair rather than replacement.
