The IPS that level of application increases recently (switching in face) effects etc. are enough uses dielectric positivity and dielectric negative liquid crystal medium in the mode similar to " guest/master " indicating meter, this in-plane-switching mode (as DE4000451, DE0588568) is particularly useful for the LCD of the upper watch-dog of modern table, and is conceived to the display application for multimedia application.
Because the operating voltage of liquid-crystal display should be low as much as possible conventionally, because use the liquid crystal media with large dielectric anisotropy absolute value, this liquid crystal media is conventionally mainly with in most cases even substantially by the liquid crystalline cpd with the dielectric anisotropy of respective symbol, the in the situation that of dielectric positivity medium the compound of positive dielectric anisotropy and the in the situation that of dielectric negativity medium the compound of negative dielectric anisotropy form.In the medium of type (dielectric positivity or dielectric negativity) separately, the electroneutral liquid crystalline cpd that is situated between is used with significant quantity at the most conventionally.Have that liquid crystalline cpd with the dielectric anisotropy of the dielectric anisotropy contrary sign of medium is conventionally few to be used or do not use.
The liquid crystal media of prior art has relatively high operating voltage conventionally looks the time of response with relative, and these are unsuitable, particularly for the indicating meter that can form image.In addition, they are conventionally unsuitable for high service temperature and/or have unsuitable low-temperature stability, and relatively disadvantageous Δ n value, as US6348244B, and CN102153442, WO9919420, the Δ n of above-claimed cpd is less.
Up to now, do not have the known series of compounds with the middle phase of liquid crystal to comprise the single compound that meets all these requirements.The research and development in liquid crystal material field are still shouldered heavy responsibilities, and in order to improve the character of LCD element, are still making great efforts to develop the compounds that can optimize this class display.
