A Study on the Spot Inspection for LCD Modules
LCD모듈의 얼룩검사에 관한 연구
Abstract
This paper suggests an automatic spot-inspection algorithm for LCD modules. Usually, LCD module testing is classified by two categories. One is for uniform pattern testing and the other is Non-uniform testing. The uniform pattern testing is well defined and also fully automated in the factory. However non-uniform pattern testing is not defined well yet, so non-uniform testing is conducted by human operators. In this paper a spot-pattern, which is one of non-uniform pattern, inspection algorithms are proposed. The performance of the proposed algorithm is tested by extensive simulations using artificial slot-patterns and real ones in the LCD modules.
