working principle monitor

The working principle of conventional monitors, CRT monitors (Cathode Ray Tube), together with the working principle of CRT-based televisions. Electrons are fired from the back of the picture tube toward the inside of the tube is coated element made of parts that have the ability to fluoresces. Electron beam passes through a series of strong magnets that bend-beam steered toward certain parts of the inner tube.

Once the beam is up to the glass tube TV or monitor, he would irradiate fluorescent coating, causing some places to glow temporarily.

Each pixel represents a certain specific place. By controlling the voltage of the beams, creating technology that can set the pixels to glow with a certain light intensity. From the pixels, the image can be formed.

In theory, to form an image, the beam was sweeping a horizontal line from left to right, causing the pixels had glowed with the light intensity according to a preset voltage. The process occurs in all the horizontal lines of pixels on the screen, and when it has to end, the ray will be dead while to repeat the same process to produce different images. So Bella can watch the object as if engaged in neither the television screen monitors.

During the early days of television, the scientists who designed the picture tube televisions and technical obstacles. As Belia know, old-fashioned TV is not yet as cool and sophisticated now, eh means not capable of displaying detailed images as it is now.

First, the fluorescent layer in the tube picture quality is not as good as now. So the quality of the resulting pixel is also not optimal as now. Now, along with the development of computer technology in need of quality tube TVs and monitors are better, fortunately the quality of phosphorescent coating inside the tube monitors have been better.

The results obtained picture tube capable of producing images with higher resolution. Fair wrote, because many computer dealing with a text, and it requires high image detail.

Unfortunately, the technology with tube CRT monitors are assumed to have many adverse effects to health users. Some research indicates that excessive exposure to monitor the eye can lead to decreased quality of vision. This is caused by electron beam radiation on the picture tube monitor or a television tube.

But people find new technologies that are ready to replace picture tubes as a means of visual display. That technology LCD (Liquid Crystal Display), which allows downsizing the dimensions and weight trimming device display monitor. In addition, one technology that is touted health familiar to users.
