LPT-4 Experimental System for LC Electro-Optic Effect
Experiments
1. Measure the electro-optic curve of the liquid crystal sample and obtain the electro-optic parameters such as threshold voltage, saturation voltage, contrast, and steepness of the sample.
2. The self equipped digital storage oscilloscope can measure the electro-optical response curve of the liquid crystal sample and obtain the response time of the liquid crystal sample.
3. Used to demonstrate the display principle of the simplest liquid crystal display device (TN-LCD).
4. Partial components can be used for polarized light experiments to verify optical experiments such as Marius’ law.
