When the brightness of the LCD display is reduced to a certain time, less obvious scanning lines will appear. This is because the display automatically reduces the frequency of the lamp.

1. The resolution setting of the LCD display

Resolution refers to the number of pixels per unit area. The LCD panel is like a small door placed to allow light to pass through. The pixels that the LCD screen can reflect are determined by the number of "small doors" per unit area, which determines the LCD display. The physical resolution of the screen is fixed. In general, the CRT display only needs to adjust the deflection voltage of the electron beam to change different resolutions.

Whether it is an LCD display or a general CRT display, resolution is the primary parameter. The display must be able to support the resolution required by the application software and hardware, but the LCD only supports the so-called real resolution, which can be compared to the highest resolution of a general CRT display. The best image can only be displayed at the real resolution.

2. The relationship between resolution and lifetime

Generally, the default resolution of a 17-inch LCD display is 12801024. For example, if it is used for 1024768, it has no effect on the lifetime except for the clarity.

3. The use of LCD display matters needing attention

① It is recommended to operate under normal temperature / humidity environment. High temperature / high humidity will affect the life of LCD display. The severe temperature shake will affect the function of the LCD monitor, especially the low temperature will affect the brightness and response time. It is advisable to work in a stable and clean environment. Dust will cause internal circuit failure.

② Do not allow liquid to splash inside the monitor. If cleaning is required, turn off the power, spray the cleaner on a soft cloth, and then wipe it gently.

③ The LCD display is made of glass. Avoid collision and vibration when moving. There are multiple layers of film on the surface. It is strictly forbidden to scratch with sharp instruments. It is not necessary to turn off the power of the monitor and unplug it for a long time.

④ It is strictly forbidden to disassemble the LCD display at will. In case of failure, be sure to ask a professional to repair it. Displaying a fixed picture for a long period of time will reduce the brightness and increase the image sticking phenomenon. It is recommended to use a screen saver.
