Comparison of photoalignment and rubbing

In this section we estimate the cost of new machines and maintenance when a photoalignment process replaces the present rubbing process. We assume the panel size to be 300 mm x 400 mm, and the light source is a high pressure mercury lamp. 

The cost of rubbing and photoalignment is therefore comparable. When the rubbing process is controlled well and no defects are found in the products, it works very well. However, once defects caused by the rubbing process are found, the 

This section summarizes some of the controllable characteristics of each alignment process.
