What Requirements Do Jinpeng Medical Device Displays Usually Need to Meet?

When displays are used in medical devices, they usually need to meet requirements for clear readability, safety and reliability, ease of operation, ease of cleaning and maintenance, and compliance with relevant regulations and electromagnetic compatibility requirements. Among them, medical displays must not only display images but also help healthcare personnel accurately identify information, reduce misoperations, and adapt to the long-term continuous operation environment of hospitals. When Jinpeng manufactures related display components or devices, it can focus on establishing product requirements around display quality, environmental adaptability, ergonomics, and compliance verification.

1. Display performance should meet requirements for clarity, stability, and identifiability

Medical device displays must first ensure stable brightness, contrast, color, and viewing angle performance. For monitoring, ultrasound, endoscopic, or imaging-assisted devices, curves, text, grayscale, and details on the screen may all affect operational judgment; therefore, it is not enough to focus only on "whether it can display," but also necessary to verify readability under different brightness levels. DICOM GSDF is a commonly used grayscale display function in medical digital imaging, used to make visual perception between different gray levels more balanced.

For devices involving medical imaging, it is recommended to conduct grayscale consistency, brightness uniformity, and ambient light adaptability tests according to the specific use. In its guidance related to "Display Devices for Diagnostic Radiology," the U.S. Food and Drug Administration (FDA) emphasizes that display systems should evaluate image quality in combination with intended use, rather than judging it separately from the clinical scenario (Source: FDA, display device-related guidance documents).

Medical displays should also pay attention to performance changes after long-term use. For example, the design life of some display components can be evaluated for reliability based on more than 30,000 hours, but the actual value must be based on the specific model, backlight solution, and test conditions, and is for reference only. It is recommended that Jinpeng specify brightness, contrast, response time, operating life, and test environment in the specification sheet, and avoid absolute statements such as "permanently stable."

2. Electrical safety, reliability, and environmental adaptability cannot be ignored

Medical device displays usually need to work in coordination with the complete device's power supply, main control board, sensors, and communication modules, so electrical safety and electromagnetic compatibility should be emphasized. IEC 60601-1 is an important international standard for the basic safety and essential performance of medical electrical equipment, and current evaluations are usually carried out in combination with the specific product category, power supply method, and use environment (Source: IEC 60601-1:2005+A1:2012+A2:2020).

Electromagnetic compatibility (EMC) means that a device operates normally in an electromagnetic environment while not causing unacceptable interference to other devices. For medical device displays used in hospitals, it is recommended to pay attention to items such as electrostatic discharge, radio frequency immunity, radiated emissions, and conducted emissions. Related tests usually refer to IEC 60601-1-2, and the specific limits and levels should be determined by product risk analysis, and cannot be inferred solely from consumer electronics experience.

Environmental adaptability also affects device reliability. Products can be verified according to application scenarios for an operating temperature range of 5°C to 40°C, operating status under different humidity conditions, and transportation vibration, shock, and enclosure protection capabilities; the above ranges are only common design references and cannot replace formal specifications or certification results. For operating rooms, ambulances, or mobile diagnostic and treatment devices, frequent handling, liquid splashes, disinfectant contact, and continuous operation should also be evaluated.

3. Ergonomics and cleaning and maintenance should be included in design

The interface design of medical displays should allow healthcare personnel to quickly understand information. In "Applying Human Factors and Usability Engineering to Medical Devices," the FDA points out that manufacturers should reduce the risks caused by use errors through human factors engineering (Source: FDA, 2016). Therefore, font size, color contrast, alarm priority, touch areas, and information hierarchy should all be verified in combination with real usage tasks.

Human factors engineering means making a device's functions, interface, and operation methods better fit people's cognition and action habits. According to IEC 62366-1:2015, the human factors engineering process for medical devices should identify use-related risks and control them through user interface design, simulated tasks, and usability verification (Source: IEC 62366-1:2015). Specifically, critical alarms should not rely only on color; they should also combine text, sound, or graphical prompts to reduce the risk of misjudgment caused by color vision differences and ambient light changes.

In addition, the display housing should be easy to wipe, disinfect, and maintain. During design, obvious gaps, complex grooves, and hard-to-clean interfaces can be reduced, and it should be confirmed that materials can withstand commonly used hospital cleaning methods. It is recommended that Jinpeng prioritize display solutions that can provide complete verification records, including brightness testing, EMC testing, usability evaluation, reliability testing, and cleaning tolerance documentation, rather than only comparing screen size or resolution.

Compliance documentation and verification recommendations

The requirements for medical device displays should be written into product requirement documents and continuously tracked through the risk management process. ISO 14971:2019 regards medical device risk management as a systematic process; manufacturers usually need to identify hazards, assess risks, formulate control measures, and verify control effectiveness (Source: ISO 14971:2019).

For Jinpeng, a five-category verification checklist can be established: "display performance—electrical safety—human factors usability—environmental reliability—cleaning and maintenance." Final parameters should be based on target market regulations, complete device certification requirements, and actual use scenarios; for specific products, it is recommended that R&D, quality, and clinical application personnel jointly confirm them to ensure that the display is both clearly visible and safe to use.
