What does a screen saver do?

The function of the screen saver is to save energy and protect the screen. Screen savers save power and, more importantly, protect your monitor. Screen protection is to prevent the screen from remaining static for too long. The color at a certain point must constantly change, otherwise it will easily cause the fluorescent material on the screen to age and shorten the life of the monitor.

The function of the screen saver is to save energy and protect the screen.

If you need to do some other things for a while while using the computer for work, thus interrupting the operation of the computer, you can start the screen saver to save the screen. The work status screen is hidden.

The screen saver has the function of saving power (because the screen brightness of some monitors is lower than the brightness during work when the screen saver is used, which helps save power), and more importantly, it can also protect your monitor. (When the screen saver is not activated) When you do not use the computer for a long time, the monitor screen displays the same picture for a long time, which will cause fatigue and discoloration of the screen light-emitting device/even burn out/eventually make the screen or a certain area biased. Color or darken.

The effect of screen saver on the monitor

The imaging principle of CRT (cathode ray picture tube) monitor is mainly to heat the cathode by the filament, the cathode emits electrons, and then in the accelerating electric field Under the action of the focusing pole, the electron beam is concentrated into a very thin beam. Under the action of the high voltage of the anode, it obtains huge energy and bombards the phosphor layer at an extremely high speed. The targets of these electron beam bombardments are the three primary colors on the fluorescent screen. For this reason, the electron gun emits not one beam, but three electron beams. They are controlled by the three primary color video signal voltages of R, G, and B of the computer graphics card to bombard their respective phosphor units, thereby displaying on the display screen. out the complete image.

For CRT, screen protection is to prevent the screen from maintaining a static image for too long. The color at a certain point must constantly change, otherwise it will easily cause the fluorescent material on the screen to age. This in turn shortens the life of the display.
