The monitor or computer screen, but it is also commonly called "screen" is a device output through an interface, shows the results of computer processing.

structure and operation of a CRT monitor.
An electron beam travels across the screen. The screen has a grid of phosphorus. If the color monitor is required 3 beams of electrons and 3 phosphors represented by point (red, green, blue)
A phosphor particle, when it is struck by the electron beam is ionized. Consequently shines. This glow is finite in time. This implies the need for a refresh to get a sense of static point (image).

reproduce or allow a greater variety of colors.
o Different resolutions can be set to monitor.
or opening in the grid monitors no vertical moire.
• CRT Disadvantages:
or occupy more space (the more thoroughly the better geometry).
or Older models have a curved screen.
or electric fields affect the monitor (the image vibrates).
or to enjoy a good image adjustments required by the user.
or opening in the grid monitors you can see several lines tensions very thin and difficult to see across the screen horizontally, you can see a white background.
• Advantages of LCD screens:

or Geometry is always perfect, is determined by the pixel size
• Disadvantages of LCD screens:
or only faithfully reproduce the native resolution, with the rest, is a black border, or is blurred by no means able repruducir pixels. O

o If you look inside the cone of visibility appropriate distort colors.
or the ADC and a DAC to reproduce color LCD monitor limits the number of representable colors.
o ADC (Analog Digital Converter) in the analog video input (number of colors to represent).
or DAC (Analog to Digital Converter) within each pixel (number of possible colors represented).
or the CRT is the graphics card in charge of doing this, the monitor does not influence the number of colors represented, except in the early models monitors that have digital inputs TTL instead of analog inputs.

o CRT can be progressive and interlaced mode , LCDs have another method of representation. In the CRT
or lose about 1 inch size, which is used to hold the tube in the CRT is pretty much occupied by the LCD.
or weight of an LCD is increased by the stand for stability, but the monitor itself weighs practically nothing.
or LCDs usually require a transformer external monitor, the CRT goes all the electronics inside the monitor.
or consumption in the LCD is smaller, and the tension of use by the electronics as well. o In the CRT can be problems of "burn" the phosphor screen, this happens when you leave a still image for long, as the word "insert coin" in the recreation in the LCD problems may be defective pixels ( always on or always off), in addition to other damages.
or blinking of both types of screens is due to the low refresh rate, coupled with persistent phosphor brightness, and the memory of each pixel on a CRT and LCD, respectively, which mitigate this defect.
o low refresh rate and a big time match persistence, no flashing, but the persistence of phosphorus is low and the soda is low, this problem occurs. Without emabargo this may cause a fade effect or blurred vision, to stay still on one point, the next screen refresh.
