TFT-LCD panel measurement System   Model LCM-3

It is well known that elastic constant is one of the most important physical properties of liquid crystal materials. For obtaining elastic constant at high precision, high-precision measurement of driving voltage (Vth) of liquid crystals needs to be conducted. Model EC-1 measures K11 (Spray) and K33 (Bend) based on Fredericks transition by applying voltage of our company’s original waveform. Dielectric constant anisotropy (De), e⊥, and e∥ can also be measured.

– CV measurement with no influence from bias voltage can be conducted.

– The elastic constant of liquid crystals can be obtained with our company’s original fitting software.
