The viscosity of liquid-crystal compounds, especially rotary viscosity γ1The response time after liquid crystal power-up is directly affected, either
Rise time (ton) or fall time (toff), all with the rotary viscosity γ of liquid crystal1It is proportional, rise time (ton) by
In related with liquid crystal cell and driving voltage, can be adjusted with reduction liquid crystal cell box thickness by the method for increasing driving voltage；And
Fall time (toff), mainly with the elastic constant of liquid crystal with liquid crystal cell box thickness related, the decline of box thickness unrelated with driving voltage
(t can be reduced fall timeoff), and under different display modes, the motion mode of liquid crystal molecule is different, tri- kinds of moulds of TN, IPS, VA
Formula respectively with average elastic constants K, distortion elastic constant, bend elastic constant inversely.
According to liquid crystal continuum theory, after a variety of different liquid crystal deform upon under external force (electric field, magnetic field) effect, meeting
By intermolecular interaction, original shape is returned in meeting " rebound "；Likewise, liquid crystal is also due to intermolecular interaction
Power forms " viscosity ".The minor change of liquid crystal molecule can make the conventional parameter performance of liquid crystal that apparent variation occur, these variations
Has plenty of certain rule, some seems to be not easy to find rule, and the interaction between liquid crystal molecule also will produce obviously
Influence, these influences are very delicate, so far also without forming very perfect theoretical explanation.
The viscosity of liquid crystal is related with liquid crystal molecule structure, studies the viscosity and liquid of the liquid crystal system that different liquid crystal molecules are formed
Relationship between brilliant molecular structure is one of the vital task of dispensing liquid crystal engineer.
