Medical device display technology is one of the important technologies in the field of modern medicine. Medical imaging technology is constantly advancing, and doctors can use imaging to diagnose and evaluate patients more accurately. Patients can also understand and comprehend doctors' explanations of their conditions more vividly through imaging. And medical display screens are playing the role of image presentation, usually using advanced TFT LCD screens, greatly improving doctor-patient communication, hospital information display, and medical center information transmission, etc. Especially after the COVID-19 epidemic, the global medical level is developing rapidly, and the demand for high-tech equipment by medical institutions is also growing. Regardless of the type of medical device, a display screen is required to present images and data. Therefore, the market demand for medical display screens is constantly increasing.
So what are the key features of medical display screens? The display scheme of medical equipment is very rigorous and has extremely high precision. Manufacturers of medical device display screens need to consider many issues and key points. For example, the reliability of the equipment cannot cause display failures during the surgical process, which will bring significant hidden dangers. The electromagnetic interference of the equipment, the adaptability of the equipment in a sterile environment, and so on. In addition, medical display screens must be able to withstand different harsh environments such as extreme temperature, humidity, and dryness. Below, we will provide a detailed explanation of the main attributes that medical display screens need to possess for these key features.
1、Medical standard electromagnetic compatibility (EMC)
We all know that in hospital wards or ICUs, there are many medical devices used to monitor and maintain patients' vital signs, such as heart rate, blood pressure, and blood oxygen saturation. This requires our medical equipment and medical display screens to work continuously 24 hours a day, which is an important manifestation of vital signs for patients. However, the operation of these devices may be subject to electromagnetic interference from other electronic devices in the environment, such as electromagnetic waves from wireless communication devices, radiation from computer equipment, electromagnetic radiation from high-voltage distribution rooms, radio waves from broadcasting equipment, and so on. In order to minimize the problems and impacts caused by electromagnetic interference, medical display devices must comply with the medical industry standards for electromagnetic compatibility (EMC). This is a unified industry standard that reduces the impact of electromagnetic interference on medical display devices to a very low standard. This will greatly reduce the generation of uncertain factors, lower the probability of medical accidents, and maintain the normal operation of medical equipment.
2、Touch surface antibacterial technology
Capacitive touch screens are widely used in various fields. Its main field lies in terminal devices, such as somoutdoor handheld devices, or personal devices such as mobile phones, PADs, etc. These are all personal devices, and now capacitive touch screens are widely used in public devices, such as shopping mall screens, library accessscreens, and so on. For our visual convenience, the problem of bacterial transmission also arises. Especially in thpost pandemic era, people's awareness of virus protection is increasing, especially in areas such as hospitals where bacteria and viruses are heavily affected. Manufacturers of medical display screens need to prioritize the issue of surface antibacterial properties in order to greatly reduce the harm of bacterial and viral transmission.
Surface antibacterial technology of LCD touch screen
How to achieve antibacterial technology on the surface of touch screens? When developing cover glass, display
manufacturers need to integrate ion silver into the glass. Trace amounts of silver ions can be lost to the surface,
killing up to 99% of bacteria and viruses. This is the glass cover plate that includes antibacterial technology. Because
silver ions are embedded in the glass composition, the antibacterial properties of the screen are continuously retained
and have the same service life as the screen, without the need for addition or maintenance during the process. Meanwhile,
trace amounts of silver ions do not affect the optical properties of the glass and have no impact on the display effect.
3、 Quality requirements for medical display screens
At present, medical institutions have increasingly high requirements for the image quality of medical equipment,
and medical display screens have stricter standards for image quality than consumer grade screens. Therefore, medical
display screens are usually equipped with image enhancement technology to ensure that the brightness displayed
remains consistent and does not deteriorate throughout the device's lifespan. At the same time, the image has no
noise, which can meet the standards of medical display.
For medical grade imaging, there are some image quality attributes: 1. High resolution - Medical equipment requires high-definition display to provide accurate images, precise details, and obtain correct diagnosis. High quality manufacturers will provide medical grade HD, 2K, 4K, and 3D display screens. 2. High brightness - Medical display screens require relatively high display brightness to enable the screen to display clear images in dark environments. 3. Ultra wide viewing angle - especially for medical equipment in operating rooms, medical staff usually need to move from multiple angles to observe data and images on the screen, which requires the ultra wide viewing angle function of the screen to support. In addition, there are requirements for attributes such as high contrast, wide color gamut, and low power consumption.
Only TFT LCD liquid crystal display products that meet the characteristics and important attributes analyzed above are recognized as qualified products by medical institutions. The medical industry is a very rigorous professional field. Only high-quality and socially responsible LCD display manufacturers can have room for development in the medical display industry.
