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.
