The difference between LCD monitor and TV and monitor is mainly manifested in three degrees: image definition, color reduction and machine stability. This is due to the application requirements of the monitor and the application environment. On the one hand, the monitor often needs a static image. It must reproduce the image information of the camera, including a lot of details, such as the local features of the object, the details can not be clearly reproduced, and the purpose of monitoring is lost, which requires a high image sharpness of the monitor; On the one hand, because the details usually include color features, it is a key requirement of the monitor, so the monitor must have a higher degree of color reduction. Because the monitor usually needs to work for a long time, the requirement of the stability of the product is very high.
