ISO 13406-2

File:ISO 13406-2.jpg

ISO 13406-2 is an international standard that specifies the ergonomic requirements for the use of flat panel displays, particularly focusing on LCD monitors. This standard is part of the ISO 13406 series, which addresses various aspects of flat panel display technology.

Overview

ISO 13406-2 was developed by the International Organization for Standardization (ISO) to ensure that flat panel displays meet certain ergonomic criteria to enhance user comfort and reduce the risk of visual fatigue. The standard outlines requirements for image quality, including parameters such as pixel defects, luminance, contrast, and viewing angles.

Key Requirements

The standard specifies several key requirements for flat panel displays:

Pixel Defects

ISO 13406-2 categorizes pixel defects into three types:

• Type 1: Always lit pixels (bright dots)
• Type 2: Always unlit pixels (dark dots)
• Type 3: Stuck sub-pixels (partial pixel defects)

The standard defines acceptable limits for each type of defect to ensure a high-quality display experience.

Luminance and Contrast

The standard sets minimum requirements for luminance (brightness) and contrast ratios to ensure that displays are easily readable under various lighting conditions. It also specifies uniformity requirements to ensure consistent brightness across the entire screen.

Viewing Angles

ISO 13406-2 defines acceptable viewing angles to ensure that the display can be viewed clearly from different positions without significant color or brightness distortion.

Reflection and Glare

The standard addresses the issue of reflection and glare, specifying maximum allowable levels to minimize visual discomfort and enhance readability.

Compliance and Testing

Manufacturers of flat panel displays can test their products against the requirements of ISO 13406-2 to ensure compliance. Compliance with this standard is often used as a selling point to demonstrate the quality and ergonomic suitability of a display.
