Reliability Test Conditions
The module undergoes high and low-temperature operation and non-operation tests to ensure reliability.

Environmental Testing Procedures

High Humidity Operation: The device is tested at 65°C and 90% relative humidity for 120 hours.
Thermal Shock (Non-operation): The device undergoes cycles between -40°C and 80°C with specific timing for each temperature and transition.
Vibration: Tested at frequencies between 5-50Hz with a scan rate of 1 octave/min for 2 hours per axis.
Drop Test: The device is dropped from a height of 120cm, covering all angles, edges, and faces.
ESD (Non-operation): Air discharge model at ±8kV, repeated 10 times.

Test and Measurement Conditions

Measurements begin after temperature stability is achieved.
Polarizer degradation is ignored for certain tests.
Evaluation Criteria: Functionality must be intact, no observable defects, luminance should be more than 50% of the initial value, and current consumption should be within ±50% of the initial value.

Inspection and Quality Control

Sampling Method: Follows MIL-STD-1916 with different levels for major and minor defects.
Inspection Conditions: Conducted at 25±5°C, 50±10% RH, and pressure between 860-1060 hPa.
Defect Classification: Major defects include non-display, line defects, and glass cracks. Minor defects include scratches and stains.
Outgoing Specification: Specific criteria for defects like glass scratches and polarizer bubbles are outlined with acceptable quality levels (AQL).

Appendices

Definitions: Includes chromaticity coordinate, contrast ratio, response time, and viewing angle.
Measurement Apparatus: Lists equipment used for luminance, contrast, response time, and viewing angle analysis.
Precautions for Handling: Emphasizes ESD precautions, handling guidelines to avoid damage, and proper assembly techniques.
Electrical Precautions: Highlights the importance of adhering to specified voltage and current settings, power on/off procedures, and power-saving techniques.

Image Sticking Prevention Strategies:

Utilize image scrolling or animation to balance pixel usage and consider sleep mode to reduce residual images and extend power capacity.
Avoid using full white backgrounds to prevent prominent image sticking; black backgrounds are recommended for power savings and better visibility.
Prevent static high-brightness displays by using auto fadeout technology.
For static logos, alternate between the original and inverse patterns to equalize pixel usage.

Mechanical Precautions:

Use cushion or buffer tape on the panel to protect against damage from external forces.
Ensure adequate space for IC placement and use a conductive layer for EMI/EMC protection.
Avoid excessive bending of films; follow specified guidelines for bending areas.

Storage and Reliability Test Precautions:

Store OLED modules at 25°C±5°C and 55%±10%RH, away from direct sunlight or UV light, and use within six months of receipt.
Reliability is guaranteed only under specified test conditions and durations.
