At present, there are four kinds of display screens used by monitors in the medical industry:
1. Digital tube (LED display): can only display digital results, can not display waveform information, simple function, has been used in the early single-parameter monitor.
2.CRT display: this is a very common display. The utility model has the advantages of high resolution, low price, large volume, not easy miniaturization of the whole machine, high pressure radiation and easy heating.
3.LCD display screen: liquid crystal display screen. Its advantages are small size, low power consumption, no radiation, no heating. In the mid-1990s, the advent of color TFT technology overcame the shortcomings of low brightness and small viewing angle of monochromatic LCD, and because the color display is pleasing to the eye and intuitive, it has been widely used. At present, the mainstream monitors at home and abroad use LCD display screen.
4.EL display screen: before the emergence of TFT display, EL display screen was once used in high-end monitors. It not only has the advantages of LCD, but also has the advantages of high brightness and large viewing angle, but the disadvantage is that the cost is very high. Therefore, with the development of TFT display screen, the application of EL display screen in the monitoring field is gradually replaced by TFT display screen.
