in fact, now many universal display technology in years ago to take root germination. At the thought of a 3 d film, for example, you can think of, like “avatar” visual masterpiece, but the 3 d movie technology can be traced back to the early 20th century. And hd 4 k (it is now 5 k) the emergence of the TV also has deep roots.
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.
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.
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.
1925-1928 – early TV function are
