EN 120007:1992

Overview

EN 120007:1992 - titled Blank Detail Specification: Liquid crystal displays – Monochrome LCDs without electronic circuit - is a European/CLC reference standard (ICS 31.120) that defines a framework specification for monochrome liquid crystal display (LCD) modules which do not contain integrated electronic driving circuits. The document supersedes CECC 20 007 Issue 1:1991 and is published in the Slovenian edition as SIST EN 120007:2005. This standard provides manufacturers, designers and procurers with a common baseline for mechanical, optical and interchangeability aspects of bare monochrome LCD panels.

Key Topics

While the full standard text contains the authoritative requirements, EN 120007 typically addresses these high‑level technical topics and requirements relevant to monochrome LCDs without built-in electronics:

• Scope and definitions for blank (no-electronics) LCD assemblies, including intended use and product classification.
• Dimensional and mechanical specifications, such as outline drawings and mounting/connector location principles to support interchangeability.
• Optical characteristics and viewing performance, including basic descriptors for contrast, transmissive/reflective behavior and viewing angle considerations.
• Materials and finish guidance to ensure compatibility with housings and environmental exposures.
• Environmental and mechanical durability expectations (storage, operating temperature, vibration and shock considerations) for use in equipment.
• Inspection, sampling and test provisions to verify conformity with the specification.
• Marking, documentation and ordering information to make procurement and traceability consistent across suppliers.

(These topics reflect the typical structure of a blank detail specification for LCD modules and help stakeholders ensure compatibility and reliable interchangeability.)

Applications

EN 120007 is practical for organizations that design, manufacture or procure monochrome LCD panels where the electronic drive circuitry is separate from the display. Typical applications include:

• Instrumentation panels and industrial control displays
• Consumer devices using discrete driver electronics
• Replacement display modules for legacy or specialized equipment
• Suppliers preparing product data sheets and mechanical drawings for OEM customers

Who should use this standard

• OEMs and equipment designers specifying display modules
• LCD module manufacturers and fabricators producing blank panels
• Procurement and quality engineers managing supplier compliance and interchangeability
• Test laboratories validating dimensional and environmental requirements
