感謝D大把ISO 13406-2搬出來讓大家增廣見聞, 但經我查訊一下孤狗大神,發現其實 ISO for LCD Pinex Defects不只有 ISO 13406-2, 所謂的ISO for LCD Pinex Defects為 ISO 13406, 其下共分四個等級,為13406-1、13406-2、13406-3、13406-4, 品質要求從高至低便是13406-1(最高等級)至13406-4(最低等級)。
請容我小小糾正一下D大,並非ISO 13406-2下分四個品質等級唷~
13406-1是class 1,面板上是容不下任何亮暗點, 13406-2則是class 2,亮暗點的容許度誠如D大所說明。 那為什麼NB大廠不直接採用class 1,就可以免去消費者要賭爛自己買NB像買樂透彩一樣呢? 以下有一家LCD公司網站上解釋得很清楚: The highest-level ISO quality standard is ISO 13406-1. This standard allows no pixel defects (as determined by their method). Only a small portion of very high-resolution LCD panels can meet this requirement, and for economic reasons, it is generally reserved for only the most critical applications.
For high quality display applications, LCD units must meet ISO 13406-2*. This standard permits a small maximum number of defects, based on the number of physical pixels on the display (native resolution). source from:http://www.edldisplays.com/whitepapers/pixeldefects.php
