For friends - friends who do not know about the history of the monitor or even the layman altogether, I want to share information about technology about how the history of computers from the beginning until now. Monitor, what happens if we play a computer without a monitor? surely many people say mending do not have a computer toys time yes? Monitor can be defined Interface or visual screen that connects between human and computer. Monitor to date has been developed in two phases. The first phase in 1855 was marked by the discovery of cathode ray tubes by German scientist Heinrich Geibler. He is the father of the tube monitor. Then, 33 years later, Austrian chemist Friedrich Reinitzer laid the foundation for developing LCD technology by discovering liquid crystals. The tube technology since the beginning was developed for realizing monitors. However, liquid crystals are still a chemical phenomenon for the next 80 years. At that time, the display frame rate or even unthought. That was the second phase of the development of computer monitors. During this time, many consider that Karl Ferdinand Braun as the inventor of the cathode ray tube. Actually, he was the first application maker for the tube, the oscilloscope in 1897. It was this device that became the basis for the development of other devices, such as television. That same year, Joseph John Thomson invented the electrons, which accelerated the development of the tube technique.
Monitor progress to date
Monitor progress is very significant from year to year. Currently there are three types of monitor technology. The three classes of technology are CRT (Cathode Ray Tube), Liquid Crystal Display (LCD) and Plasma gas.
1. Cathode Ray Tube
Brown Tube Technology (CRT Display) was invented in 1897, but this technology was only adopted as a television broadcast receiver in 1926. The history of the invention of CRT technology has been more than 100 years and has a very good image quality. However, this technology has one weakness that is the bigger the display will be made, the larger the tube is used.
On a CRT monitor, the viewer screen used is a cathode ray tube. This technology raises the display on the monitor by emitting an electron beam to a point on the screen. The rays will be reinforced to show the bright side and be weakened for the dark side. CRT technology is the cheapest technology compared to the other two technologies. However, the resulting resolution is good enough for various purposes. It's just that the electrical energy required is quite large and has a fairly strong electromagnetic radiation.
2. Liquid Crystal Display (LCD) or Flat Display Panel (FDP)
LCD monitors no longer use electron tubes but use fluorescent liquid crystals that can fluoresce. This technology produces monitors known as Flat Panel Display with flat-shaped screens, and higher resolution capabilities compared to CRTs. Because of its flat shape, the flat type monitor uses a small amount of energy and is widely used on portable computers.
Another advantage of the LCD monitor is the brightness ratio that has touched the number 350: 1. Brigtness ratio is the ratio between the darkest display with the brightest display.
Liquid Crystal Display uses liquid crystals that can fluoresce. The liquid crystal is a viscous organic molecule that flows like a liquid, but has a spatial structure like a crystal. (discovered by the Austrian Botanist - Rjeinitzer) in 1888. By shining the light through a liquid crystal, the intensity of the outgoing rays can be electrically controlled so as to form flat panels.

The layers in an LCD:
- Polaroid back
- Rear electrode
- Rear glass plate
- Liquid Crystals
- The windshield plate
- Front electrode
- Polaroid front
Electrodes in the coating serve to create an electric field in liquid crystals, whereas polaroid is used to create a polarization. In terms of price, LCD monitors are much more expensive when compared with CRT monitors. And some weaknesses that still have such as less able to work in various resolutions, such as monitors with a resolution of 1024 X 768 will seem somewhat blurry if employed at a resolution of 640 X 420. But lately the weakness has begun to overcome with anti aliasing.
3. Gas Plasma or Organic Light Emitting Diode (OLED)
This type of monitor combines CRT technology with LCD. With the resulting technology, capable of making the screen with LCD-like thinness and viewing angle that can be as wide as CRT.
Plasma gas also uses phosphorus as well as on CRT technology, but the screen on plasma gas can be perpend without the help of light behind the scenes. It will make the absorbed energy not as big as the CRT monitor. The resulting color contrast is even better than LCD. This gas plasma technology can often be encountered during musical performances or spectacular sports events. There is a giant monitor screen mounted at certain corners of the arena. That is a monitor that uses plasma gas technology.
After we see the rapid development of LCD, we can now see the latest FDP development that we can say as Flat Panel Display Future. Why this latest FDP we call FDP the Future? Because the next 5-10 years may be LCD Technology will be replaced by this FDP Future. This Future FDP is based on active matrix technology Organic Light Emitting Diode (OLED).

maybe so much that I can tell about the history of the monitor
