TV sets range from black and white to color, from tube and transistor TV to integrated circuit TV, To today's intelligence. Today's TV has entered thousands of households, but how many people can understand the development of the TV? Let's walk into the development of the TV.
1925: Prototype of TV
Talking about the birth of the TV set, there is a British name that has to be mentioned. John Lodge Baird, the father of the TV set, used to get a clear image and increased the current to 2000 volts. I accidentally touched the cable and almost died of electric shock.
Of course, Baird's efforts were well rewarded in the end. In 1925, Baird showed a very practical TV set in the UK. From the current point of view, the mechanical equipment exhibited by Baird is very simple. This TV set is basically made of scrap.
Optical equipment is the lens of some bicycle lights. The frame is made of enamel pots, and the wires are a messy messy web of things. The biggest miracle is that these poor quality materials, once arranged, can produce images, and this has become the prototype of modern TV sets.
1939: The first black and white television set
After Baird invented a television device that could map images, the technology quickly developed rapidly. In 1939, the first black and white television set was born in the United States. On April 30, US President Franklin Roosevelt was in New York. The city of Frasin Square gave a speech at the opening ceremony of the New York World Expo. His audience includes tens of thousands of guests on the scene and a small number of other people in New York City. The latter number is less than 200, and they listen to the president's voice in a way that is familiar to modern people - watching live TV.
There are two protagonists at the opening ceremony of the New York World Expo: one is a leader who delivers a passionate speech, and the other is a television camera 50 feet away from him. At the New York World Expo, in addition to the highways, skyscrapers, etc. that were on display, television became the most popular protagonist.
1950: "Lazy bones" remote control available

1954: The first color TV set
In the 1950s, it was the era when televisions became popular. In 1953, American RCA set the national color TV standard, and in 1954, the first color TV was introduced. By 1964, 31% of American households had color. TV set. Although color TV technology has been around for more than a decade, the image quality at that time is still unflattering; the cost of the device is still high; people watching TV still like to watch black and white TV; cable TV networks rarely play color TV programs. . NBC broadcasts the largest number of color TV programs, just because its parent company RCA was the leader of color TV manufacturers at the time.
1958: China's first black and white television set
On March 17, 1958, this was the "birthday" of China's first black-and-white television set. After the founding of New China, China has never had a TV broadcast. In order to be in line with foreign countries, in 1957, New China decided to develop its own TV broadcasting business. At that time, the tenth bureau of the Second Ministry of Machinery Industry of the Ministry of Electronics Industry handed over the task of developing the TV launching center equipment to the Beijing Broadcasting Equipment Factory. The task of developing a television receiver was handed over to the state-owned Tianjin Radio Factory.
At that time, the state-run Tianjin Radio Factory set up a special research group with a total of 8 people, all of whom were top technicians and workers in the factory. On the evening of March 17, 1958, the TV center of China first broadcasted TV programs in Beijing.

prototype. At 7 o'clock in the evening, the image of the broadcaster appeared clearly on the first TV screen of China and accompanied by a loud voice. The prototype test passed 100%. China's first black and white TV set was successfully developed.
1960: In the first presidential debate on television, Marseille Senator J. F. Kennedy took the audience from the sweaty Vice President Nixon and won the election.
1967: The first Trinitron TV
In the 1950s, although Sony's black and white TV was sold, its technical competitiveness had no advantage. All of this changed in 1967, when a young member of the Sony engineering team cleverly solved the problem that color TVs have always had: image distortion and light divergence. Sony called the new product "Terry" (meaning a grid color picture tube).
In 1968, Sony sold the first "Terry" TV. Smart consumers realize that Trinitron is a super product, and the enthusiasm of consumers has contributed to the success of Trinitron. Between 1968 and 1988, Sony sold 1.8 billion Trinitron, and Trinitron also won the reputation of "the best selling model ever."
1977: The first portable TV
In the 1970s, it was still the era of rapid development of television sets. In 1973, first of all, digital technology was first used in television broadcasting, and experiments proved that digital television can be used for satellite communications. In 1976, the UK completed a study of the "TV Library" system, where users could search for news, books, or magazines directly from television. In 1977, the UK developed the first portable TV sets, which made consumers realize that in addition to being used in the living room, TV sets can be carried around during business trips.

2000: Health TV concept
In the late 1990s, the homogenization competition of domestic TV sets was very serious. At that time, some domestic manufacturers often used the cost performance of products as the focus of publicity, and attracted sales by price reduction. However, Skyworth was the first in China in 2000. Introducing the Healthy 1250 TV, this TV overcomes the shortcomings of analog TV field flash, line flash, and thick lines, and is compatible with HDTV.
2011: Cloud TV

It implements cloud-based, cloud services, cloud communities, cloud browsing, cloud search, cloud applications and other cloud-based personalized applications on TV, and can be used with mobile phones at any time. Mobile devices such as tablets are interconnected, and cloud servers provide data processing and resource integration for the background, allowing users to share various videos, photos, and materials anytime, anywhere.
2008: China's first domestically produced plasma screen TV
Since the 2007 Changhong officially launched the plasma screen project, Changhong, together with Rainbow and American MP, invested 675 million US dollars in the first phase of the plasma screen project; in July 2008, the annual output of plasma screen reached 2.16 million (in 42" ).
In the end, through the third phase of construction, the total investment exceeds 2 billion US dollars, forming an annual output of 6 million plasma modules, and entering the ranks of the world's top four. The first phase of the plasma project is expected to achieve mass production in 2008. This will be the first plasma screen multi-faceted production line in China, mainly producing plasma screens of 42, 50 inches and larger.
2011: Brainwave TV
Today, when TV display technology is very mature, will there be new changes in future TV products? Perhaps control will become a new breakthrough point. On July 18, 2011, the world's first brainwave TV was shocked at the "Shanghai Casadi News Conference". Haier's remote operation of this epoch-making TV is done through a brainwave headset.
This special brainwave headset detects the user's brainwave signal and recognizes the user's state and converts it into a digital signal that the TV can recognize. In the future, we no longer need a TV remote control. It is free to control the TV switch and switch channels with your own will.
2012 Year: 4K TV
On the last day of 2013, Skyworth released the first 4K home Internet TV in China. Earlier, its TVs controlled by WeChat were also introduced to the market.
