What is the main difference between an LCD monitor and an LCD monitor?

The basic performance of the LCD monitor is mainly reflected in three degrees: image sharpness, color reproduction, and overall machine stability. This is determined by the application requirements and application environment of the monitor.

On the one hand, monitors often need to monitor still images. It must realistically reproduce the image information captured by the camera, including many details, such as the local characteristics of the subject. The details cannot be clearly reproduced and the monitoring is lost The purpose of this is to require the monitor to have high image sharpness; on the other hand, because the details usually include color characteristics, which truly reflects the color characteristics of the subject, which is also a key requirement of the monitor, the monitor must High color reproduction; in addition, because the monitor usually requires long-term uninterrupted work, product stability requirements are also much higher than other display devices. By grasping these three elements, you can basically distinguish the performance of the monitor.

Liquid crystal monitors and liquid crystal displays are display devices. The main principles of the two are not much different. Both use current to stimulate the imaging of liquid crystal molecules. However, the purpose of monitors and displays is different. It can be seen literally that the monitor is used for the computer and the monitor is used for monitoring the system.

The difference between LCD monitors and LCD monitors lies in the following seven points:

First, the degree of radiation is different

      CRT monitors generally use a metal case to shield electromagnetic radiation, and the CRT display plastic case does not have strong radiation suppression. LCD monitors and displays basically do not radiate electromagnetic waves, but LCD monitors are usually all-metal cases that are effective in shielding external strong electric field interference.

Second, color reproduction ability

      The monitor will realistically reproduce the monitored scene and strive to be realistic. The monitor renders the image, and the picture quality is more suitable for viewing, so it cannot restore the real monitoring scene.

Third, the resolution is different

      CRT monitors can generally reach 625 lines (interlaced) / 1250 (progressive) lines, and the number of CRT scan lines is significantly lower. The resolution of an equivalent size LCD monitor is comparable to that of an LCD monitor.

Fourth, the refresh frequency is different

      The refresh rate of ordinary color monitor should be below 50Hz (analog), and the average computer monitor can easily reach 75hz.

V. The input signal interface is different

      The monitor inputs AV analog video signals and is compatible with some other signal sources such as VGA and YPbPr; computer monitors generally only input RGB signals of the three primary colors for connection to a computer.

6, the core components have different performances

      The CRT monitor uses a special picture tube to recognize and recognize colors better than the CRT display, and can more accurately reproduce the collected source image. LCD monitors use special LCD panels, which have higher physical performance than equivalent displays, such as viewing angle, response time, and brightness.

7. Different components

      The components used in the monitor are designed to have greater current, power consumption, temperature and resistance to electrical interference, electrical shock and redundancy, and a higher average time between failures; therefore, the stability of the monitor is better.
