Optimal liquid crystal amount and sufficient margin control for best display quality

Abstract

The phenomenon of a liquid crystal (LC) display panel includes deterioration with time, the quality management being monitored, gap-induced faults in harsh conditions such as high temperature, depressurization with low temperature, and hitting on the panels to remove the possibility of any problems at anywhere in the world. Therefore, obtaining the LC amount margin is very important at up and down enough margins by any changes in the environment. In particular, we derive the main factors affecting for well-management of the LC amount margins due to the increasing complexity of the panel architecture and the development of materials when there are frequently a lot of changes. A method was found to approximate the three-dimensional structure in the panel to reflect the measured values as representative values; based on such values, a simulation system that automatically generates the structure based on the design file was built. To evaluate the consistency, we compared the actual LC amount for 14 products and the simulation calculated value and secured an accuracy of about 98.9% the result of the comparison between the real and simulation, including the margin section, secured a linear correlation of 92.6%, and its consistency was verified. It has been verified that the amount of LC drop can be automatically adjusted.
