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

• terrestrial
television (TVB)
• Cable TV
• Satellite TV
• Mobile TV
• Network 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.
