Active matrix is a type of addressing scheme used in flat panel displays. In this method of switching individual elements (pixels), each pixel is attached to a transistor and capacitor actively maintaining the pixel state while other pixels are being addressed, in contrast with the older passive matrix technology in which each pixel must maintain its state passively, without being driven by circuitry.
Liquid crystal composite and electro-optical display device comprising same
The invention provides a liquid crystal composite for an active-matrix-addressed electro-optical display device and application of the liquid crystal composite. The liquid crystal compound comprises a compound with a general formula (I) which occupies 10 percent to 30 percent of the total weight of the liquid crystal composite, a compound with a general formula (II) which occupies 5 percent to 30 percent of the total weight of the liquid crystal composite, a compound with a general formula (III) which occupies 10 percent to 40 percent of the total weight of the liquid crystal composite, and a compound with a general formula (IV) which occupies 10 percent to 60 percent of the total weight of the liquid crystal composite. The liquid crystal composite provided by the invention has a relatively high response speed and good low temperature storage stability. The invention further provides the active-matrix-addressed electro-optical display device comprising the liquid crystal composite.
