Problems solved by technology

[0011] However, in the traditional unipolar driving method, four different potential values ​​must be provided on the common and segment wires, so it is necessary to use a four-level common and segment wire driver
The design of this kind of driver is more complicated and requires more power supplies

Embodiment Construction

[0031] Please refer to FIG. 3 , which shows a partial cross-sectional view of a fast multi-stable liquid crystal display in an embodiment of the present invention. The display 10 includes a first substrate 12 . The first substrate 12 is formed by an insulating material (such as glass, plastic or some other polymer material), which can be an indium tin oxide coated soda limestone glass substrate produced by Donnelly Applied Films. (ITO coated sodalime glass substrate), silicon glass substrate produced by Corning, ITO coated plastic substrate produced by Southwall Technology, or any of them combination. Substrate 12 has a first and second major surface 14 and 16 . A conductive material layer 18 is disposed on the first main surface 14 of the substrate 12 . The conductive material layer 18 must be transparent. Therefore, the electrode layer 18 can be a thin metal layer, such as silver, copper, titanium, molybdenum or a combination thereof, but its thickness must be extremely ...

Abstract

The present invention relates to a driving method for display, which is applied on a display. It comprises the following steps: apply a first signal on a common line, which is switched between a first electrical potential and the ground potential, so as to select the pixel; apply the second signal on the segment line of the selected pixel, which is different in phase with the first signal and which is switched between the second and third electrical potentials, so as to drive the selected pixel into a reflective state; apply the third signal on the segment line of the selected pixel, which has the same phase as the first signal and which is switched between the second and third electrical potentials, so as to drive the selected pixel into a transparent state; apply the fourth signal fixed at the fourth electrical potential on the common line of the selected pixel, so as to release the selected pixel; wherein the first, second, third, and fourth electrical potentials have the same polarity with respect to the ground potential, and their values are made such that the differential signal between the common line and segment line in each pixel is centered at the ground potential in each pixel.

Description

technical field [0001] The invention relates to a liquid crystal display, in particular to a fast multi-stable liquid crystal display using cholesterol liquid crystal material. Background technique [0002] In recent years, the research on liquid crystal display materials has led to the development of a new type of cholesteric liquid crystal structure material and components. This liquid crystal material has a periodically changing optical structure that can reflect light. It includes nematic liquid crystals with positive dielectric anisotropy and chiral dopants. This material is generally called polymer stabilized cholesteric texture (PSCT) or polymer free cholesteric texture (PFCT). [0003] Liquid crystal displays using reflective cholesteric liquid crystal structure materials are generally referred to as "fast multi-stable liquid crystal displays" (FMLCD). Reflective cholesteric liquid crystals (PSCT and PFCT) have two stable states at zero electric field. One is the...
