2 Definition of rubbing strength To describe the rubbing strength quantitatively, a definition of rubbing strength is required. The structure of a rubbing machine is shown as Fig. 20. It consists of a rotating drum covered by a cloth whose surface is made of short fibres, and © 2005 Kohki Takatoh, Masaki Hasegawa, Mitsuhiro Koden, Nobuyuki Itoh, Ray Hasegawa and Masanori Sakamoto 24 Masaki Hasegawa Analyzer Polarizer φin Rubbing direction Y X IR light Z (a) X Z Y +θin IR light Rubbing direction Analyzer (b) Fig.
3 Applications Almost all of the present LCD manufacturers adopted the rubbing process to control the LC alignment. If the alignment of the LC is not uniform or the alignment strength is weak, alignment-related defects appear, such as disclination lines, reverse twist, and reverse tilt. These defects have large effects on the image quality of the LCDs because of light reflection from the defect interfaces or because of the electro-optical characteristic differences. Therefore, controlling the alignment defects is a very important issue for LCD manufacturing.
The relationship between the surface tension of the alignment layer and the pretilt angle of the LC does not always hold. The relationship holds only in the case of certain materials and certain conditions. The surface tension depends on the surface roughness. Rubbing increases the surface polarity because of merging of the side chains into the bulk and also increases the surface roughness in the case of strong rubbing. In this way, the surface tension increases as a result of rubbing, but this can be regarded as an unimportant side effect.
