| LCD Wall Brackets protect years of Innovation Television has revolutionised communication, education and how people spend their recreational time.� TV as we know it is quite a recent invention, many families only purchased their first set in the 1950s and 1960s.� Recently other technologies have been introduced to household TVs with the aim of further improving picture and sound quality.� In addition to this, new screen types can reduce the amount of space a large TV takes up in a room, especially when wall mounted (for example plasma screen and LCD wall brackets are easily obtainable).The history of the television is full of contributing scientists and inventors from different countries.� Their work, and later the work of electrical engineers, enabled the production of the very first TVs.� Although the concept of transmitting images telegraphically had been in existence for a while, Paul Nipkow enabled progression to be made through his invention, the ‘Nipkow disc’ in the 1880s.� This creation was utilised in a publically displayed mechanical television in 1926.� The machine was demonstrated in Soho, London, and had been made by Scottish inventor, John Logie Baird (13-08-1888 – 14-06-1946).� It is maybe not surprising that John Logie Baird showed an interest in similar technology from an early age.� Reputedly he performed experiments at his parent’s house as early as 1903, unsuccessfully attempting to construct a selenium photo electric cell.� By the 1920s, Alan A. Campbell-Swinton, an electrical engineer based in London proposed a new way of producing an electrical television using Cathode Ray Tubes as both transmitters and receivers.� At this point, several others were already experimenting on methods of producing electronic TVs.� Two of these were American born Philo Taylor Farnsworth, and Russian- American Vladimir K. Zworykin, the designer of the iconoscope.As CRT (Cathode Ray Tube) television was gradually becoming more and more efficient, so was another new technology that would one day surpass it.� Studies into Liquid Crystals had begun in the late 1800s, surprisingly, after Friedrich Reinitzer discovered that cholesterol extracted from carrots was crystalline in nature.� From this point onwards, experiments into the potential of Liquid Crystals continued, and in 1972, the first active-matrix Liquid Crystal Display (LCD) panel was produced in the US.� CRT televisions have been widely used since around the 1950s in many households.� More recently, the two concepts that had grown alongside each other for over a century have been combined, and LCD TVs have been available to consumers for a number of years.� It is said that at the end of 2007, worldwide sales of LCD TVs outnumbered those of CRT TVs for the first time.When sitting down to relax of an evening, watching your favourite show, it sometimes helps to remember all the hard work that went into making your viewing possible.� It is almost impossible for some generations to imagine a time before TVs, so important have they become to modern culture.� The latest flat screens have also been perfected over the years, and are a product of many great minds and hours of experiments and research.� Modern TVs are quite amazing (and expensive!) bits of equipment, so make sure they are correctly looked after, and fixed using LCD wall brackets when necessary.���� |
