What is IEC 61747191Ed12018

IIntroductory Paragraph

The IEC 61747-1-9-1Ed1 2018 standard is an important document in the field of electronics and display technology. It provides guidelines for the characterization and classification of active matrix liquid crystal displays (LCDs), commonly known as TFT-LCDs. In this article, we will delve into the details of this standard, exploring its scope, key concepts, and applications.

IIUnderstanding the Scope

The IEC 61747-1-9-1Ed1 2018 standard primarily focuses on LCD modules used in consumer electronics such as televisions, laptops, and smartphones. It establishes criteria that manufacturers must adhere to when measuring and reporting various parameters related to the performance of these displays. The scope also extends to the measurement methods for determining pixel defects, color gamut, luminance, and other relevant characteristics.

IIIKey Concepts and Requirements

One of the key concepts addressed in this standard is the determination of pixel defects. Defects may manifest as stuck or dead pixels, bright or dark sub-pixels, or full pixel failures. The standard defines specific acceptance criteria based on pixel density, allowing manufacturers to assess the quality of their LCD displays accurately. Additionally, the standard outlines requirements for measuring color gamut, viewing angles, response time, contrast ratio, and other critical parameters that impact image quality and user experience.

IVApplications and Benefits

The IEC 61747-1-9-1Ed1 2018 standard serves several important purposes in the electronics industry. Firstly, it acts as a reference for manufacturers, ensuring consistency in testing procedures and reporting formats. Secondly, adherence to this standard enhances consumer confidence by providing accurate and comparable information about the quality of LCD displays. Finally, it stimulates healthy competition among manufacturers, encouraging them to continuously improve their products to meet the stringent requirements set by the standard.
