Liquid crystal display device Part 20-3.Visual inspection of active matrix color liquid crystals Display module1 ScopeThis part of GB/T 18910 gives the quality assessment process for visual inspection of transmissive active matrix color liquid crystal display modules with human eyes. Detailed requirements and general rules of the sequence, this section includes defect definitions and visual defect inspection methods. Note 1.This section does not include moiré, because it has not yet been clearly specified. Note 2.The limitation of defect type, quantity and size is stipulated in the quality contract (customer acceptance specification, warehousing inspection specification).2 Normative referencesThe following documents are indispensable for the application of this document. For dated reference documents, only the dated version applies to this article Pieces. For undated reference documents, the latest version (including all amendments) is applicable to this document. GB/T 18910.102-2021 Liquid crystal display device Part 10-2.Environmental, durability and mechanical test methods Durability (IEC 61747-10-2.2014, IDT) 3 Terms, definitions and abbreviations The following terms, definitions and abbreviations apply to this document. 3.1 General Visual inspection A method of displaying defect inspection by human eyes. Note. The requirements for displaying defects depend on the agreement between the customer and the supplier. Therefore, the limited sample size, under clear observation and operating conditions, it is obvious The defect level shown is for reference only. 3.2 Defect Any observable abnormal phenomenon that appears in the effective display area. (See Figure 1 for classification) Example. Figure 1 shows the division of defects into two categories. The first type of defects are defects with clear boundaries, and the second type of defects are defects with unclear boundaries. The latter category There is no clear definition of deficiencies, so it is difficult to assess. So the second category of defects is not included in this section. ...... |
