비주기적인 패턴을 이용한 moiré 개선 시트에 관한 연구

Nowadays, the display industry is an integral part of an electronics industry. There are many patterns of light accumulation sheet in display industry. And the patterns have a regularity which is a high frequency. That has a problem which is a moire looks like a movement of huge wave. The solution that is suggested is chaos patterns of sheet. And we used a piezo actuator to vibrate a manufacturing bite for roll-to-roll mass production. We made chaos patterns on sheet through a controlling the direction of vibration as a normal, parallel, and spiny. And we measured a moire and brightness for three conditions. So result of the third condition which is a condition of spiny direction was the best on brightness and reduction of moire. We suggest that engineers have to study about controlling a vibration frequency and displacement by a variable factor.
