From electronic wooden boxes to flat screens televisions, TVs have undergone massive changes in size, design, and technology over the last century. The first working TV was invented in 1924, by a Scotting engineer, and was nothing more than cardboards, bicycle lamps and wax scraped and put together to transmit images within a few feet. The model gained popularity and used a mechanical rotating disc to display images, and tickled everyone’s curiosity for TVs.
In the early 1940s, black and white televisions came in vogue and worked using the phosphor-coated screen which represented an image, when an electron beam painted that image on it resulting into a black and white image.
It was 4 years later, in 1928, that color TVs were invented. The colored TVs used cathode ray tubes technology whereby, three electron beams one for each additive primary colour (red, green, and blue) generated colored images on the TV. However, with the exorbitant prices, TVs remained a luxury until the 1950s when prices fell drastically, making TVs affordable for the masses. During this period, televisions came in wooden boxes with doors that hid the screens when not in use. They were also heavy and large in sizes to accommodate the CRT technology. It was in the 1950s, that the first electronic TV remote was invented to control televisions from a distance.
In the 1960s, LED TVs were introduced but were monochromatic in design and did not gain much popularity. LED TVs use light emitting diodes (LED) as backlight to transmit pictures, and can be sleeker in design compared to LCDs. Over the decades, however, LED TVs have undergone significant changes and advancements in technology and design, and have become the preferred choice for televisions in the 21st century.
In the 1970s came the flat screen LCD and plasma TVs. These TVs were sleeker than the older TV models since the screens were made of liquid crystals pressed between two sheets of glass and were used to display pictures with the help of a backlight and the control of electricity voltage.
Around 1997, the manufacture of OLED TVs was started, which used ‘organic light emitting diodes.’ OLED technology can be found in some premium models of TVs and smartphones.
The 4K TVs followed the OLED TVs in 2013 and provides a minimum resolution of 3,840 pixels wide and 2,160 pixels high, making it the equivalent of two 1080p screens in height and in length. These TVs are expensive since they come with the latest technology and provide better viewing experience than normal LEDs.
An important development among TVs was the invention of Smart TVs, which allowed your TV to connect to the internet and access online applications.
With the advancement of technology and the advent of ecommerce, now it is possible to buy a TV online, whether you are looking for a 4K LED TV, or a normal LED TV, and have it home delivered at no extra cost. You can also buy 4K TVs online that are equipped with OLED technology to have the optimal viewing experience.
