What might happen if the phosphor coating in a CRT is damaged?

If the phosphor coating in a CRT (Cathode Ray Tube) is damaged, image quality may degrade. The phosphor coating is responsible for emitting light when struck by electrons emitted from the CRT's electron gun. If this coating is compromised, it can result in uneven illumination, color inaccuracies, or a complete loss of image in certain areas of the screen. These issues directly affect the clarity and vibrancy of the display, leading to a subpar viewing experience. Therefore, a damaged phosphor layer can significantly impair the performance of the monitor, making it difficult to view images clearly.
