Color TV

“Television has proved that people will look at anything rather than each other.” by Ann Landers {Journalist}

Color TV or Television is a device who play color video image. It is improve device of the earliest television technology. Television broadcasting stations and networks in most parts of the world upgraded from black and white to color transmission in the 1960s and 1970s. The invention of color television standards is part of the history of television, and is described in the technology of television.

Color television is possible because the human brain can convert a grid of differently colored dots (usually known as pixels, short for picture elements) into a complete color image. Color television cathode ray tubes have three electron beams, as opposed to single electron beam in a black and white TV. The screen is coated with red, green and blue phosphor dots placed behind the holes of the tube’s shadow mask. All the observed colors are combinations of the red, green and blue signals (that is, if all dots are firing, the image appears white).

The fact that color television is essentially only three times more complicated than back and white television means that the basic invention processes for the two devices almost took place simultaneously. John Logie Baird (1888-1946) is recognized as a leading pioneer in the development of television, alongside Philo Farnsworth and in 1928 Baird first demonstrated the transmission of color images.
One of the early important commercial consideration was that the signals that transmitted the color pictures should not only result in color images on “Color TV” sets but should also be rendered as black and white images mono sets. Development was slow and sales of shadow-masked RCA cathode ray tube color TV sets only started in 1954. The sets were extremely expensive and typically cost more than $1,000. The 1961 Sunday evening transmission of “Walt Disney’s Wonderful World of Color” encouraged U.S. citizens to buy color TVs. Only by 1972 were color TV sales exceeding black and white.
