概述
In this course, we will go though the basic knowledge and skills to work with liquid crystals. The 1st part of the course is a series of introductory talks about the physical properties of liquid crystals. The 2nd part introduces the four typical liquid crystal operation modes, which are IPS, VA, ECB, and TN. We will analyze the cell structure, the materials, the assembly, the operation, and their characteristic properties.
