computer screen technologies

cathode ray tube (CRT) monitors
This type of screen uses CRT technology, which was considered the most used in television screens, and this technology uses a current of electrons, which is characterized by being highly energy-intensive; To help form images on the fluorescent screen, the basis of the cathode ray tube is an empty tube with an electron gun at one end, and a fluorescent screen at another end. This type of screen has disadvantages and advantages, which are the following:

Disadvantages of CRT monitors: This type of monitor has many drawbacks, as follows:

  1. Heavy weight.
  2. Large size.
  3. of high cost.

Advantages of CRT monitors: This type of monitor has many advantages, as follows:

  • It has a quick response.
  • It has multiple screen resolutions.

liquid crystal displays (LCD

This type of screen uses LCD technology, which is one of the most used technologies today, and usually includes a layer of color, or monochrome pixels arranged in lines between two transparent electrodes, two polarizing filters, and a mechanism for creating the optical effect in them. By polarizing light in multiple quantities and passing it through the liquid crystal layer, it is worth noting that LCD technology is divided into two parts: 

TFT Active Matrix, Passive Matrix Technology, Active Array Technology is known to generate better image quality, safer and more reliable, and one of the negatives of the passive matrix is ​​that it has a slow response time, in addition to being outdated, and this type of screen has disadvantages and advantages, which are as follows:

Disadvantages of LCD screens: This type of screen has many disadvantages, as follows:

  1. Its price is relatively high.
