Requirements for Medical Display Modules

Medical displays are not simply “brighter and more expensive monitors”. They are system-level engineering products, covering optics, electronics, grayscale fidelity, long-term stability, and regulatory compliance.

This blog provides a technical, engineering-oriented breakdown, clearly distinguishing:

• Mandatory requirements
• Advanced requirements for high-end or diagnostic-grade displays

1. Classification of Medical Displays

Grade	Typical Use Cases	Stringency
Observation / Clinical Review	OR auxiliary displays, patient monitoring, endoscopy, PACU, bedside viewing	★★★☆☆
Clinical (General Clinical Use)	Routine clinical image review, department workstations	★★★★☆
Diagnostic	Radiology, mammography, pathology, image-based diagnosis	★★★★★

Important:
Most products marketed as “medical displays” only meet observation-grade requirements.
True diagnostic-grade displays are far more demanding, with a significant cost gap.

 

2. Optical & Display Core Requirements (Most Critical)

2.1 Resolution & Size Matching (Mandatory)

Principle:

• Image pixel resolution should match the native panel resolution
• Strong interpolation or upscaling that affects diagnostic fidelity is unacceptable

 

2.2 Luminance (Brightness) (Mandatory / Stricter for Diagnostic)

Grade	Typical Peak Luminance
Observation	≥ 300 cd/m²
Clinical	≥ 400 cd/m²
Diagnostic	≥ 1000 cd/m² (Mammography ≥ 2000 cd/m²)

Requirements:

• Long-term luminance decay ≤ 10–15%
• Stable operation under continuous use

Common Techniques:

• LED constant-current backlight driving
• Integrated luminance sensor (for closed-loop control)

 

2.3 Contrast Ratio & Black Level (Mandatory)

Typical Targets:

• Observation / Clinical: ≥ 1000:1
• Diagnostic: ≥ 1500–2000:1

Black level must be minimized, especially for lung and soft-tissue visualization.

 

2.4 Grayscale Performance & DICOM GSDF (Mandatory for Diagnostic)

This is one of the fundamental differentiators of medical displays.

• Diagnostic displays must comply with DICOM Part 14 (GSDF)
• Displays without DICOM GSDF compliance cannot legally be marketed as diagnostic displays

Technical Requirements:

• True 10-bit grayscale (1024 levels)
• Diagnostic-grade commonly uses 12-bit LUT + 10-bit panel
• Long-term grayscale consistency without drift
• Support for automatic or semi-automatic DICOM calibration

 

2.5 Color Performance (Application-Dependent)

Application	Color Requirement
Ultrasound / Monitoring	sRGB, 8-bit sufficient
Endoscopy / Surgery	High color gamut & color accuracy
Pathology	High color accuracy, ΔE ≤ 2

High-end configurations:

• Adobe RGB ≥ 90%
• True 10-bit color depth
• Long-term color stability

 

3. Stability & Reliability (Critical for Medical Use)

3.1 Long-Term Stability & Aging (Mandatory / Diagnostic Critical)

• 24/7 continuous operation
• Aging tests ≥ 10,000–50,000 hours
• Controlled drift in luminance, grayscale, and color

 

3.2 Luminance Uniformity (Mandatory / Diagnostic Critical)

Grade	Uniformity Target
Clinical	≥ 80–85%
Diagnostic	≥ 90–95%

Typical Techniques:

• Panel-level zone compensation
• Factory uniformity correction LUTs

 

3.3 Viewing Angle Consistency (Mandatory)

• IPS or equivalent wide-view technology
• No grayscale distortion with viewing angle changes (critical for diagnosis)

 

4. Hardware & Mechanical Design (Often Underestimated)

4.1 Electrical Interface (Mandatory)

Common Interfaces:

• DisplayPort (preferred)
• DVI (legacy systems)
• HDMI (not preferred for medical-critical use)

Requirements:

• Stable high-resolution output
• EMI robustness for medical environments

 

4.2 Surface, Housing & Medical Environment Compatibility (Mandatory)

• Easy to clean
• Resistant to disinfectants

Optional Enhancements:

• Liquid ingress protection (IPx1 / IPx2)
• White or medical-gray surfaces to reduce reflections

 

4.3 Power System Reliability (Mandatory)

• Medical-grade power design
• Strong EMI / ESD immunity
• Strict leakage current control

 

5. Software & Quality Control (Invisible Core)

QA / QC System (Mandatory for Diagnostic)

• Individual factory calibration report per unit
• Per-unit LUT calibration
• Full serial-number traceability

 

6. Regulatory & Compliance (Critical)

Category	Standard
Electrical Safety	IEC 60601-1
EMC	IEC 60601-1-2
Medical Software	IEC 62304
China	NMPA (formerly CFDA)
USA	FDA (Class I / II)
EU	CE / MDR

DICOM Compliance Declaration (Diagnostic Mandatory):

• Explicit statement of DICOM Part 14 support
• Test and validation documentation

 

7. Engineering Summary
