Color monitors using cathode rays picture tubes (CRT) and color monitors using liquid crystal displays (LCDS) differ in the principle of image reproduction, which uses a magnetic deflection drive to implement a field scan (also known as an analog drive), while the latter uses a dot-matrix driven approach (also known as a digital drive). As a result, the former often uses the view of electricity to define its sharpness, while the latter defines its resolution by the number of pixels.
The sharpness of the CRT monitor is mainly determined by the width of the monitor's channel band and the point spacing of the picture tube, as well as the convergence error, while the latter is determined by the number of pixels of the LCD screen used. CRT Monitor has the advantages of low price, high brightness, wide viewing angle and high service life, while LCD Monitor has the advantages of small size (flat shape), light weight, no flashing image without radiation, but the main disadvantages of LCD monitor are high cost, narrow angle of view (image dimming when viewing on the side, color drift is very anti-color), The service life is short (usually the LCD screen after 5,000 hours of the burner its brightness drops to less than 60% of the normal brightness, but the average life span of the CRT can be more than 30,000 hours) and other shortcomings.
