Google is your friend for a question like this. I started searching and, surprisingly(?) "cleanroom classes for lcd" produced a lot of relevant sounding hits.
I think try need to refine your question if you want a proper answer. What level would your research be operating at? "Clean" is a relative term (hence the many different classes) If you can afford some failures than you don't need the level of cleanliness of a complex manufacturing process. This link should equip you to make decisions about what you may want. But it's only a start.
 

1. What is a Cleanroom ISO Class?

A Cleanroom ISO Class is a classification system that measures the level of cleanliness and particle count in a cleanroom environment. It is based on the number of particles of a certain size per cubic meter of air.

2. Why is it important to use a cleanroom for Liquid Crystal research?

Liquid Crystal research involves highly sensitive materials that can easily be contaminated by particles in the air. A cleanroom with a controlled environment helps to minimize the risk of contamination and ensures accurate and reliable results.

3. What are the differences between different Cleanroom ISO Classes?

The main difference between Cleanroom ISO Classes is the maximum allowable number of particles per cubic meter of air. The lower the ISO Class, the cleaner the environment. For example, an ISO Class 1 cleanroom allows a maximum of 10 particles of size 0.1 micrometers per cubic meter of air, while an ISO Class 9 cleanroom allows a maximum of 9,000,000 particles of the same size per cubic meter of air.

4. Which Cleanroom ISO Class is suitable for Liquid Crystal research?

The recommended Cleanroom ISO Class for Liquid Crystal research is ISO Class 5 or higher. This means that the cleanroom environment should have no more than 100 particles of size 0.1 micrometers per cubic meter of air. However, the specific ISO Class may vary depending on the requirements of the research and the sensitivity of the materials being used.

5. How is the Cleanroom ISO Class determined?

The Cleanroom ISO Class is determined by conducting particle count tests in the cleanroom using a laser particle counter. The results of these tests are then compared to the ISO Class standards set by the International Organization for Standardization (ISO) to determine the appropriate classification.
