The invention of television In 1900, "television" the word has emerged. (John

Logie Baird), he was called "the Father of the TV. "Also in that year, Americans the Si Fuluo gold (Vladimir Zworykin) the invention of television, John Logie Baird television system with Sifu Luo gold has very different. The history of John Logie Baird's television system called mechanical television, Sifu Luo payment system is called the Electronic TV. This difference is mainly because of the transmission and reception of the principle of different.

Television Division• Black and white TV• Mechanical TV• Electronic TV• Color TV

Black and white TV

  One can only display black and white TV. In the earlier days of television

Mechanical television 1884 German inventor Nipkow (Paul

Nipkow) that visual residual principle invented the "scan turntable, the use of electronic scan images to photosensitive plane via selenium

Dynamic image, then dial more in the second scan objects many times in order to show the full action.

Electronic TV CRT monitors constructed mainly by the electron

gun, coil (Deflection coils), mask (Shadow mask), phosphate phosphor layer (phosphor) and glass screen

Color T V

Color TV is the subtractive color mixing red, blue, and green primary colors of light to a clever combination of color TV.

TV signal transmitting and receiving divided

By signal type: • Analog TV • Digital TV

Press the classification transmission:

• terrestrial television (TVB)

• Cable TV • Satellite TV • Mobile TV • Network TV • TV

Digital TV Able to directly receive and deal with foreign

TV digital TV signal, or built-in digital TV decoder TV, commonly referred to as "digital TV (IDTV).

Digital TV Digital TV refers to the type of television transmission,

reception for all aspects of digital television signals from the studio to the transmitter, or to spread the system all the signal propagation through the digital stream composed by 0,1 digit string. The loss of signal reception.

LCD monitors LCD monitors pixel of the liquid crystal display consists

of the following components: suspended between two transparent electrodes (indium tin oxide) of a nematic liquid crystal molecular layers on both sides of the outside of the mutually perpendicular directions of polarization of the two polarization filters.

Plasma Display Panel Plasma display (Plasma Display Panel, referred to as

plasma), also known as plasma display is a flat panel display screen,

3D TV The 3D TV using the visual characteristics of the

eye to produce three-dimensional. Cylindrical lens Lenticular This feature makes it the image has the role of

"compression" and "isolation" by many structural parameters and performance identical cylindrical lens. Cylindrical lenticular from different angles to many images recorded in the same picture on the stripe state.

Current state of television technology

the current TV technology, one of the most obvious feature is digitized.. In addition, the broadcasters are phasing out the traditional analog cameras and videotape, digital camera, and various emerging record carrier. This change greatly improved the quality of the image.

The status of the TV Now most people use the TV volume compared to a

decade ago and not much smaller. CRT technology is still the most commonly used display technology. The biggest drawback of this technique is the size of the screen and proportional to the volume. along with the digitization of television production and transmission technology, the receiving device Digitized also become inevitable., has more features, including thus breaking the tradition of the TV.
