| Popis: | 101 With the digital video around the world trend of the times, the display panel technology is constantly upgrading, we should use the "look" to deal with a lot of things need to meet all the needs and feelings visually. Consumers its quality requirements is increasingly high, the various displays gradually high brightness, uniform, thin volume and power saving. The area ratio of the brightness, viewing angle and color gamut is a focus buy LCD or other display device specifications, but also affect the performance of LCD color reference value, its importance is of course the ineffable. LCD panel products, high quality display can show the color capabilities, the monitor assembly of color filters (Color Filter, CF) is a critical components, plus CF process in the display material occupied. The cost of a very high proportion of its costs account for about 20 to 30 percent of the TFT-LCD material cost ratio. Therefore, in the enhancement of the production yield of CF considerable benefits on the profit of the whole display. Yield enhancement element is to identify the cause of the poor quality factors. Defect inspection of the color filters are divided into two categories, a macroscopic defects the check (Macro-Defect) other microscopic defects (Micro-Defect). This study will process for RGB primary colors often occurred microscopic defects; black defects, white defects automatic optical inspection system lighting parameters to adjust, optimization of the various types of defect detection. |
