The history of television in the world is not particularly old. Today, those in their 40s and 60s know how fast the technology of television is changing. 4 decades ago people tied curtains in the middle of the road, watching movies with rented sixteen MM projectors. The film appeared and faded on both sides of the screen. As the wind blows and the curtains move, the size of the cast becomes thicker, thinner, longer, shorter. However, the road on both sides of the screen would be crowded with spectators. The picture was so blurry that the open air could only be taken at night. Another advantage is that the traffic problem is not particularly noticeable.
Many of the old TV boxes the size of Patara are remembered today. Some people get unhappily sad by playing ‘Jane kahan gaye wo din’. Of course, it was fun to sit together and watch TV and movies, but some people think that neither I love, I love summer, nor I love Hush. The reality is not so much that the best entertainment and recreational technology is rife around us that it is no longer worth it, but teenagers and young adults are still interested in the new technology. The tendency to acquire and discover this new thing is in the mind which keeps the world economy afloat. Mobile phones, televisions, movie projection, etc., have undergone such rapid and massive changes that man does not even have time to stay up to date with them.
Speaking of television screens, LCDs and plasmas came just a few years ago. Then the LEDs came and now OLED and other new type of TVs have come and some are coming so keep earning and keep getting it done. The way we are doing in the case of cellphones and motorcars. The image of LED TV is brighter and clearer with high definition. While the effect of colors and contrast of colors on the OLED screen seems more enjoyable. But the significant difference between the two is that the OLED TV screen does not have a light source at the back so its screen can be kept even thinner than the LED.
It looks like a sack that encloses with a drawstring. However the construction of OLED screen is more complicated than LED. That’s why OLED TVs are more expensive than LEDs. It costs twice as much as an LED of the same size. But people today buy a smartphone worth Rs 1.5 lakh and replace it using a maximum of 3 years, they will also need OLED TV. The difference between LED and OLED (OLED) is that LED is a liquid crystal (inorganic light emitting) diodes based technology whereas OLED is based on organic light emitting diodes. In simple language one of the diodes is inorganic while the other is organic.
Improvements in OLED and LED technology indicate that in the near future, television screens will be both round and fully transparent, like glass. This means that we can also stick a TV on a large frame of a photograph of a family member. When the TV is on, more colorful, clearer scenes can be seen on the TV, and when it is off, people can see family photographs (or anything else) on the wall. South Korea’s Samsung and TCL Electronics, the world’s largest maker of televisions, are focusing on electronics LED TVs. Against this, only South Korea’s LG has focused on OLED.
Together, the three companies account for more than 40% of the world’s television sales. The LED term or name does not fit scientifically for LED TV. In fact, the most important part of the screen is the ‘liquid crystal’. These crystals are very small, electronically controlled type of shutters (or shutters) that allow or block the required amount of light. What we call ‘pixels’ are the finer parts of a picture and they all come together to form a picture.
Each such individual pixel contains a trio of crystals mentioned above. These three different ways control the movement of the three colors, considered primary or base, red, green and blue. Behind this three color administration system is a bright and white backlight produced by today’s light emitting diodes. The technology previously housed white fluorescent bulbs as a source of light. OLED TVs, on the other hand, have no backlight or rear lighting system. The crystals in OLED are organic and each crystal glows when it is given an electric current.
But since those crystals are made of different types of organic matter, they emit light in different colors and shades. This is how many types of colors are mixed. There is another difference between OLED and LED. When the OLED pixel is switched off, its color changes to deep dark black, but on the other hand, even when the LED is turned off, its shutters allow some light to escape and so it appears in gray, not black. Thus, the published and unpublished pixels do not have as much contrast as the OLED. This means that the colors are brighter in OLED TVs while in LEDs it is gray or dull.
Micro-LED technology has now been developed as a solution to this backlight problem. Compared to normal LEDs, these micro LEDs are so subtle that they can be combined to form palette like OLEDs. Samsung has created a TV called ‘The Wall’. The distance between its two corners is more than 12 feet. On the other hand, Sony company from Japan has also developed TV panels with Micro-A LED system. A picture of a TV can also be seen in one of the panels of this panel and if you arrange the panels next to each other like the tiles of the bathroom wall, the picture will also get bigger.
Suppose you can make a large TV screen from a modular screen panel. It is being used in sports grounds and for other commercial purposes and will now be available in the market for home use. If you don’t want to take the tension of paying EMI, you can make the TV bigger and bigger by buying one more panel when you have the money. Samsung unveiled a 110-inch micro LED TV at the world-famous Consumer Electronics Gathering in Las Vegas last year.
Why go to the cinema if you have a TV 9 feet or bigger in the house? In this age of OTT, requests have to be made to no longer serve entertainment. Invitations to watch have to be turned down. If such TVs can be scratched like paper on the doors of the house, then the little bit of life that has survived in the cinema theaters will also be gone. However, the price of this 110 inch TV will be more than 1 crore 15 lakh rupees. However, as sales increase, so will the cost of production. It will happen that the middle class children will now go to the house of the rich just like the children of the neighbors used to go to the house of the TV house.
Initially expensive when it comes to new technology in electronics. In 1954, the Westinghouse Company launched the first color TV in the United States with a price tag of over Rs. If the new equipment is successful, the bulk of the production will be cheaper. By 1960, the price of a color TV had dropped from 200 to 300 300. However, micro LED LED TVs have about two and a half crore LEDs. So microscopic that its size is in microns. Properly arranged, it takes a lot of work to get the most out of it. It requires a lot of precision. But Samsung claims that the company has developed a technique for knitting these fine micro LEDs. Samsung has developed special chips for that by modifying the chips. Seeing Amitabh’s ‘wall’ on the wall, it will be necessary to ask, where did he go?
