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.
- Estimation of future defects via accelerated aging test
- Quick measurement and evaluation time
