Title: (EN) DYNAMIC DRIVE METHODS AND APPARATUS FOR BISTABLE LIQUID CRYSTAL DISPLAY
(KO) 쌍안정의 액정 디스플레이용 다이나믹 구동 방법 및 장치
Abstract: front page image
(EN)

PURPOSE: An electronic driving system is provided to update display information swiftly with a bistable charily mantic liquid crystal material.

CONSTITUTION: A display state of the pixel under the polar(60a) is controlled by the voltage gap between the polar(80a) and the polar(60a), and three polars(80a,80b,80c) are connected with each other, because of the electronic lead connected to the input of the edge. According to the material of LCD, voltage gap between the polar(80a) and the polar(60a) is controlled and optical chracter of the pixels is controlled selectively.
