Overview
IEC TR 62728:2011 is a Technical Report from the IEC that provides an overview and explanation of differences in terminology used in flat panel display technologies - specifically liquid crystal displays (LCD), plasma displays (PDP) and organic light emitting diode displays (OLED). The report clarifies why the same or similar concepts are defined differently across the separate product standards. It is explanatory and non‑normative: it does not introduce new definitions or requirements but explains the background and reasons for the variations.
Key Topics
- Comparison of terminology used across display technology standards (LCD, PDP, OLED).
- Explanation of background and rationale for differences in wording - reflecting technology characteristics, historical development, and differing standardization work‑flows.
- Cross‑reference to normative definitions contained in individual IEC standards rather than replacing them:
- Guidance for interpreting terms when reading product standards, technical specifications, test reports, and procurement documents.
- Clarifies that the report is informational and does not change existing normative definitions.
Applications
Who uses IEC TR 62728:2011 and how it adds practical value:
- Standards developers and committees - to harmonize wording and understand why terms differ between display technology standards.
- Manufacturers and product engineers - to interpret requirements consistently across LCD, PDP and OLED documentation when designing or labeling displays.
- Test laboratories and certification bodies - to align test reports with the correct normative definitions and avoid misinterpretation of terms.
- Procurement specialists and spec writers - to ensure product specifications refer to the correct IEC normative definitions and avoid ambiguous language.
- R&D teams and technical writers - for clear communication in datasheets, white papers and regulatory submissions.
This Technical Report supports interoperability, consistent product documentation, and clearer communication across the display technology ecosystem by explaining terminology differences rather than redefining terms.
