  LCDBoth LCD splicing screen displays and LCD splicing screen displays are devices, and their main principles are not much different. Both use current to stimulate liquid crystal molecules for imaging. However, the purpose of the monitor and is different. From the literal meaning, it can be seen that displays are used for computers and monitors are used for monitoring systems. In addition, there are other differences. Next, we will analyze the differences between LCD monitors and LCD splicing screen displays. The difference between LCD monitors and LCD splicing screen displays mainly lies in the degree of radiation: CRT monitors generally use a metal shell to shield electromagnetic radiation, while CRT monitors have a plastic shell that does not strongly suppress radiation. Monitors and displays generally do not emit electromagnetic waves, but LCD monitors typically have an all metal casing that is effective in shielding against external strong electric field interference.

Color reproduction ability:LCDWe will faithfully reproduce the monitored scene and strive for authenticity. The monitor will render the image, which is more suitable for viewing, so it cannot restore the real monitoring scene. Different resolutions: CRT monitors generally have up to 625 lines (interlaced)/1250 lines (progressive), and the number of CRT scanning lines is significantly lower. The resolution of LCD monitors of the same size is equivalent to that of LCD splicing screen displays. Different refresh rates: The refresh rate of a regular color monitor should be below 50Hz (analog), while a typical computer monitor can easily reach 75Hz. Different input signal interfaces: The monitor inputs AV analog video signals and is compatible with other signal sources such as VGA and YPbPr; Computer monitors generally only input VGA signals of RGB primary colors and are used to connect to computers.

And the performance of the core components applicable to LCD advertising machines is different: CRT monitors use dedicated cathode ray tubes with stronger color recognition and identification capabilities than CRT monitors, and LCD advertising machines can reproduce the collected source images more realistically. The LCD monitor uses a dedicated LCD panel, which has higher physical performance than equivalent displays, such as viewing angle, response time, brightness, etc
