From 3 inches box to LED

A 21-year-old Philo Taylor Farnsworth invented the world’s first electronic television.

If we were to ask where he drew his inspiration from- Philo Taylor Farnsworth lived in a house without electricity. From the age of fourteen, he imagined a system which would capture moving images. Philo Taylor Farnsworth’s invention was far better than any other television system invented to date because the system was highly capable of capturing moving images through beam of electrons.

A long line was the first sign transmitted by Farnsworth through his experiments conducted on the first television set devised by him.

John Baird emerged with the first commercially produced television set which was unveiled in 1928 to the public. Based on John Baird’s original invention, the first color television set was introduced by CBS.
When the decade of 1970 commenced, Sony introduced the first ever video cassette which was called the “U-Matic Series.” Being the first commercially produced videocassette prototype, it was a ¾ inch tape and had a maximum playing time of 60 minutes which later became extended to 80 minutes.

Following Sony’s lead, Philips Corporation introduced a home video cassette format in the same year which was made available for the home consumers.

The LCD Discovery

A botanist Friedrich Reinitzer accidently discovered a strange material that exhibited a mesophase during one of his experiments. The material discovered by him was cholesteryl benzoate.

Friedrich Reinitzer discovered that the liquid at the mesophase housed a characteristic of a crystal. As the material had the characteristics of both liquid and crystal, Friedrich Reinitzer named it “fliessende krystalle” and the English equivalent name “liquid crystal” was ultimately born. Thus came into existence “Liquid Crystal.”

The LCD theory was further developed at RCA laboratories. Richard William who was a RCA researcher discovered that liquid crystals exhibited some interesting electro-optic characteristics. Richard William generated stripe patterns in a thin layer of liquid crystal material by applying voltage. The patterns which were produced consisted of long parallel regions which he referred to as “domains.” Through his experiments, William was able to conclude possibility of liquid crystals as electro-optical elements for display devices.

When Play station entered the Home entertainment

Sony and Nintendo were in together to bring the Play station to the home consumers market.

By 1988 Nintendo was ruling the gaming market. Sony and Nintendo were partners in the development, but Nintendo was also involved in the development of CD-ROM drive with Philips Corporation.
