Since the evolution of modern science, television is the most revolutionized invention for mass communication. It has allowed us to see the limits of our imagination to become reality without even putting the effort. You can see what is happening in the world just by sitting in your house or office. You can gain knowledge, entertain yourself, look over the market currents, and know the deeply hidden histories of anywhere.
Let me enlighten you on how the television revolutionized from old times of the 80s and 90s to the new generation.
• Cathode ray tube
The cathode ray tube made televisions are the very first televisions that were made. The cathode ray tube is a vacuum tube that contains some number of electric guns that are accelerated and deflected to form the images. CRT televisions were basically lower-definition television. They did not have precise resolution and the images. These were only capable of analog broadcasting.
• Digital light processing
After the invention of CRT Televisions, the DLP projectors came into action. Some of the DLP projectors have TV tuners, and therefore, they are considered as a type of television. They are usually suitable for official work and educational purposes.
The plasma television was the enhancement in the household televisions. These are flat-screen TVs and have a width of not more than 30 inches. The plasma televisions have a standard-definition resolution because the improvisation was done with better display quality and so they are capable of analog as well as digital broadcasts.
• Liquid crystal display
The LCD television sets are the ones that use liquid crystal display technology for the image display. These television sets are much more thin and lighter than the CRT and plasma sets. The LCD TV sets are of two types, the ones which are simply called LCDs and the ones that use LED in backlight, known as LEDs. Since 2010, LCDs and LEDs are the most used television sets, and they have surpassed the sale of CRT TVs. LCDs are mainly high definition TVs, with higher resolution and better projection.
• Organic light-emitting diodeThe OLEDs are having an emissive layer of organic compound that emits light in response to electric current. This light due to the compound effect is responsible for the digital display over the screen. The OLEDs are used in all kinds of electronic devices with a screen like PCs, smartphones, tablets, etc. OLEDs are mainly the Ultra high definition televisions as they have the highest resolution and bright and clear projection that is capable of noticing every tiny detail. The OLEDs are mainly smart TVs, thus by their help, we can not only watch our DTH but also online programs as they work as a computer also.
The television we see now has the world in itself as we can see thousands of channels on it. From DD National to Netflix and Amazon prime, today’s television has everything. No wonder you can say that the television in our home has taken our expanded universe in a simple compact electronic box.
