碩士 === 國立交通大學 === 電子物理系所 === 92 === The surface of substrate plays an important role in liquid crystal devices. Rubbed polymer layers are widely used to control the alignment of LC molecules, but the small area and multi-domain alignments can not be achieved.
If the alignment of small area can be achieved, the application of small LC components will be much further extended and the functionality of Micro-electromechanical system (MEMS) can be increased by including LC components
We develop a new LC alignment method (the fiber tip method) to align LC on a small specific areas
The single etched fiber tip is used to scribe the polyimide (PI) coated substrate to make grooves on PI. The fiber is fixed on a 3-axes linear stage. By controlling the speed of fiber movement , the distance and angle between the fiber and the PI surface, we can get grooves with various micro structures and periods.
In this work, we measure the anchoring strength, transmissions, and the pretilt angle in different conditions and determine the alignment effect with respect to the scribing conditions.
