look at the bottom of the timeline, it will provide you an overview of the past century and a half in a brief history of display technology.

A ground-breaking:

CRT ( cathode ray tube) and pave the way for early detection of

1897 – CRT birth

as a Nobel Prize winner, an outstanding physicist and inventor, as well as Karl Ferdinand Braun (Carl Braun), built the first to CRT (cathode ray tube). The CRT contains a can by electron beam hitting a phosphorescent surface to create the image of vacuum tubes. Later, the technology is used in the early images on TV and computer monitors.

1907 –

the discovery of electroluminescence

British radio researcher Henry Joseph found electroluminescence Round. Electroluminescence is a natural phenomenon, which laid the foundation for later development of LED technology. That same year, Russian scientists Boris course for the first time to use CRT to simple geometric image display on the TV screen.
