Description
Technical field
The present invention relates to a kind of liquid-crystal composition more particularly to a kind of liquid-crystal compositions applied to onboard system, belong to
Liquid crystal material technical field.
Background technique
It being significantly improved with the rapid development of our country's economy with national life level, automobile entered common people house,
More people are higher for performance and the comfort requirement of automobile, and former people get used to the mechanical instrument by orthodox car
Disk reads all data (such as speed per hour, oil consumption, mileage number) of automobile, and innovation and communication network now with science and technology
Fast development, people need terminal presentation facility that is more intuitive, more modernizing to meet the instant messaging of people, navigation and
Amusement.Therefore vehicle-mounted liquid crystal display is just ready to appear, is applied to the characteristics of its distinctive light, low power consuming and colorization
Replace old-fashioned mechanical display on automobile, realizes digitlization display function, the car running computer display screen on such as medium-to-high grade vehicle, for showing
Show the average fuel consumption of automobile, instantaneous oil consumption, outdoor temperature, average speed, driving time, single mileage travelled, service cycle leads
Boat and multimedia recreation.
Common liquid crystal display is divided into TN-LCD (Twisted Nematic-LCD, twisted nematic LCD), STN-LCD
(Super TN-LCD, super twisted nematic LCD), DSTN-LCD (Double layer STN-LCD, double layers super twisted nematic LCD)
With four kinds of TFT-LCD (Thin Film Transistor-LCD, thin film transistor (TFT) LCD).TFT screen point many kinds: VA (PVA,
SVA), S-IPS, TN etc., TN-TFT display contrast height due to its fast response time, to light and heat stability, temperature range
The advantages that wide, is extremely suitable for use in in-vehicle display system, can show under high and low temperature environment, good to light and thermally stable, display
Stability and high reliablity, in recent years, with the intelligence and multifunction of in-vehicle display system, for onboard system exploitation
TN-TFT liquid crystal material has been applied in onboard system, and foreign countries are mainly that Germany MERCK and Japan DIC supplies such product, state
Interior excellent product supply market not yet.
Summary of the invention
