Abstract
In recent years, the demand of touch panel increases rapidly. The new input interface is gradually affecting people's usage of various electronic products. Touch panel is often equipped with flat-panel displays, so it must be transparent well and invisible. The defect of touch panel appearance has to be inspected critically. At present, the appearance quality of touch panel has been determined subjectively by means of human visual inspection. However, large amount of various defects make opeartors hard to remenber, and different opeartors may judge the same defect with different defect code. As a result, it makes inspection outcomes faithless and increases the difficulty of inspector training.This research focuses on the improvement of touch panel inspection training and inspected process to increase inspector’s certificated ratio and reduce products scrapped ratio. Through factory on-site obervation and consulting with experienced and new inspectors, the training situation was realized. The training materials were reedited using the rule of memory. Such as “Classified defects”, “different color impression”, “illustration”, “different layout”, and “mulit-perception”. The modified training materials have been verified to be truly helpful for inspector’s learning and increase certificated ratio. At practical inspection workstation characteristics of visual perception ( different luminance contrast ) was applied to increase hit rate. The written test average score from 81.5 to 92.2, the operation test average score from 67.4 to 76.5. Besides, a new carrier and packaging have been designed to reduce product damage, the scrap ratio from 8.2% to 4.9%.This research provides a simple hybrid application case. Applying knowledge of human visual inspection on the modification of training program, a practical inspection problem has been solved. This improving process can be generalized to other inspection station.
