With the rapid development of the medical field, people’s requirements for medicine are getting higher and higher. The appearance of LCD screens has improved the efficiency of hospital outpatient management, reduced errors and omissions, reduced the labor efficiency of medical staff, and improved the quality of patient service. As a key part of terminal equipment, medical liquid crystal display bears key responsibilities, directly endangering all its normal operation and characteristics. There are so many LCD screens on the market now, how should we choose?
1. Digital tube LED display information: only information data can be displayed, not information waveform information content. The system has simple functions and is used for the monitoring of a single main parameter in the initial stage.
2. CRT monitor: It is a very wide range of monitors. Its advantages are high screen resolution and relatively economical price. The disadvantage is that it is large in size, the whole machine is not easy to be miniaturized, and there is a high-pressure radiation source, which is easy to generate heat.
3. LCD screen: At present, most popular ECG monitors around the world use LCD screens. The utility model has the advantages of small size, low functional loss, no radiation and no thermal damage. The emergence of TFT-LCD display screens get rid of the shortcomings of pure color LCDs with low chromaticity and small angles. In addition, because the color display makes people relaxed and happy, and the brand image is visualized, it is quickly widely used in the field of diagnosis and treatment.
4. EL display: Before the TFT display appeared, the EL display was used as an ECG monitor. In addition to the advantages of LCD, it also has the advantages of higher brightness and greater angle. The disadvantage is that the cost is high. Therefore, with the development trend of TFT display, the application of EL display in the monitoring industry is gradually replaced by TFT display.
