Does the screensaver hurt the LCD monitor?

The core structure of the LCD (liquid Crystal Display) is a liquid crystal molecule filled with motion in the middle of two glass substrates. The signal voltage directly controls the switching state of the film Crystal, then uses the transistor to control the liquid crystal molecule, the liquid crystal molecule has the obvious optical anisotropy, can modulate the light emitted from the backlight lamp, realizes the image display. A complete display is made up of a number of pixel points, each pixel being like a transistor that can be switched on. This allows you to control the resolution of the display. If the resolution of an LCD can reach 1024 x 768 (XGA), it is represented by a 1024x768 pixel point to display. That is to say why the best resolution of the LCD is fixed, and why the LCD refresh rate is only 60Hz.

So a LCD is showing the image, the LCD molecule has been in the working state of the switch, for a response time of 20ms LCD work 1 seconds, the LCD molecule has been switched around hundreds of times. and the number of switches of liquid crystal molecules will naturally be limited by life, to the life of LCD will appear aging phenomenon, such as the bad points and so on. Therefore, when the computer stop operation also let the screen display colorful repeated movement of the screen saver will undoubtedly make the liquid crystal molecules are still in the repeated switch state.

Because many of the screen saver now in order to improve the performance and color changes, has been used as an animation to make, some even 3D animation, but also the graphics processor to deal with, so many large screen saver came into being, so the screensaver for the computer hardware has become a great burden, This is a serious departure from the original intention of maintaining the computer.

In addition to say a few digression, is due to cope with the changing, and color details rich screensaver, CPU, hard disk and display card workload may be higher than normal application, if the use of battery-powered notebooks, such a screensaver has undoubtedly become a battery killer.

In the final analysis, different principles of the display should use different maintenance methods, the best way to rest the liquid crystal display is to turn off the display.
