CG-100

 

The CG-100 cell gap and twist angle measurement system is a powerful microscopic system.

It can be used to determine the cell gap and twist angle of an arbitrary twisted liquid crystal cell quickly and accurately.

The rubbing directions and twist sense can also be determined.

This measurement system can be used for transmittive, reflective as well as transflective LC cells.

It is based on several proprietary HKUST technologies.

EO-100

 

The EO-100 LCD electro-optical characterization measurement equipment is a microscopic based equipment. It serves to measure both static and dynamic properties of a LCD. There are four electrical driving schemes provided which include driving schemes with different multiplexing numbers (N) and bias ratios (S). The characteristic voltages such as V10, V50, V90 are automatically determined.
