IEC EN 62341-5-3 Organic Light Emitting Diode (OLED) Displays - Part 5-3: Methods for Measuring Image Adhesion and Lifespan

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 62341-5-3 testing. IEC EN 62341-5-3 specifies standard measurement methods for determining the image adhesion and lifespan of organic light-emitting diode (OLED) display panels and modules, excluding final display products for end customers such as TV sets, monitor sets and mobile devices. The measurement method for the service life mainly applies to modules.

This edition includes the following important technical changes from the previous edition:

• The lifetime measurement tool is for the module only;
• Changing the measurement method for monitor or TV devices;
• Digital signage display is included as an example of OLED devices;
• Added metering method with HDR (high dynamic range) for image sticking;
• Analysis method is added with CIEDE 2000 for image splicing;
• The information method is modified to assess image adhesion.

Standard measurement ambient conditions specified in IEC EN 62341-6-1 will be applied. For image adhesion measurements, the ambient temperature should be controlled as 25°C ± 3°C, otherwise a temperature-controlled detector should be used. (The stability of the LMD will be less than 1/5 of the intended brightness and color perception difference levels.)

Warm-up time is defined as the time from the moment the supply voltage is turned on until repeated measurements of the display show a change in brightness of less than 2%/min. Repeated measurements should be made for a period of at least 15 minutes after starting. The brightness changes during the total measurement should also not exceed 5%.
