Historical Development of Computer Monitors

Monitor is the most important interfaces that connect people and PC. At the time of the first computer to operate in 1938, the monitor was 83 years old. Its development is ongoing to this day.

History Monitor
Stage of development of Computer Monitors in use today is actually divided into two phases. The first phase in 1855 was marked by the discovery of cathode ray tube by scientists from Germany, Heinrich Geissler. He is the father of the monitor tube. Then, 33 years later, the Austrian chemist, Friedrich Reinitzer, laying the basis for developing LCD technology with discovered liquid crystals. Tube technology since it was originally developed to realize the monitor. However, the liquid crystals is still a chemical phenomenon during the next 80 years. At that time, the display frame rate or even yet thought of.

During this time, many thought that Karl Ferdinand Braun as the inventor of the cathode ray tube. Actually, he is the maker of the first applications for the tube, ie the oscilloscope in 1897. The device that is the basis for the development of other devices, such as television or radar screen. In the same year, Joseph John Thomson discovered the electron, which accelerates the development of the tube technique.

The first CRT Monitor (Cathode Ray Tube) was developed to receive television broadcasts. Milestone was the first television tubes from Wladimir Kosma Zworykin (1929), electronic full frame rate of Manfred von Ardenne (1930), and the development of the first cathode ray tube that can be reproduced by Allen B. Du Mont (1931).

In earlier generations of computers, not to use a special monitor as it is today. Computer time was connected with the family as a TV viewer screen of data processing is done. That is quite a problem is that the resolution of the TV monitor when it is only capable of displaying 40 characters horizontally on the screen.

Special monitors for computers issued by the IBM PC, which initially has a resolution of 80 X 25 with color capability "green monochrome". This monitor is capable of displaying the results of a brighter, clearer and more stable.
In the next generation of emerging mono graphics (MGA / MDA) which has a 720x350. Furthermore, in the early 1980s came with a CGA type of monitor resolutions range from 160x200 to 640x200 and color capabilities between 2 to 16 colors. EGA monitor comes up with a better resolution of 640x350. Monitor type is fairly stable until the advent of next-generation Windows computers.
