1. Image processing: TVs usually watch rapidly changing moving images and have poor image processing capabilities for still images. Monitors mainly monitor still images, so they are more professional in image processing. Professional LCD monitors have bandwidth compensation and enhancement circuits, with video bandwidth reaching 20M, greatly improving clarity. Professional 3D digital comb filters enhance brightness, chromaticity digital noise reduction processing capabilities, and motion detection capabilities, significantly improving the smoothness of moving image edges, greatly enhancing the sense of hierarchy of the image, better representing details, and making the image more delicate and natural.
2. Color reproduction degree: If the clarity is mainly determined by the amplitude frequency characteristics of the video channel, the reproduction degree is mainly determined by the phase of the chromaticity signal and brightness signal of the three primary colors of red (R), green (G), and blue (B) in the monitor. Due to the fact that monitors usually observe static images, the requirement for color reproduction on monitors is higher than that on televisions. Therefore, professional LCD monitors should have precise compensation circuits and delay circuits in brightness, chromaticity processing, and R, G, and B processing to ensure phase synchronization between brightness/color signals and R, G, and B signals.
3. Stability of the whole machine: When forming a closed-circuit monitoring system, the monitor usually needs to be continuously powered on 24 hours a day, 365 days a year (while the television usually only works for a few hours a day), and some monitors may have harsh application environments, which requires higher reliability and stability of the monitor. Compared to televisions, in terms of design, monitors have much higher current, power consumption, temperature, resistance to electrical interference, electrical shock, margin, and mean time between failures. Additionally, monitors must use fully shielded metal casings to ensure electromagnetic compatibility and interference performance; In terms of component selection, the voltage resistance, current, temperature, humidity, and other characteristics of the components used in monitors are higher than those used in televisions; In terms of installation, debugging, especially for the aging process of components and the whole machine, the requirements for monitors are also higher. When manufacturing televisions, the aging of the whole machine is usually carried out on the assembly line at room temperature for about 8 hours, while the aging of the monitor needs to be carried out on the aging assembly line in a high-temperature, high humidity and sealed environment for more than 24 hours to ensure the stability of the whole machine.
