Embodiment Construction

[0024] The arbitrary area display driving method of the present invention is applicable to various smectic liquid crystal screens. For example, the smectic phase liquid crystal screen may include first and second base layers, and a mixed layer comprising smectic phase liquid crystals and additives is arranged between the first and second base layers, and the smectic phase liquid crystals may be Class A smectic Phase liquid crystal, etc., the additive is a compound with conductive properties, such as hexadecyltriethylammonium bromide, etc. The first conductive electrode layer is plated on the side of the first base layer facing the mixed layer, and the second conductive electrode layer is plated on the side of the second base layer facing the mixed layer. The first conductive electrode layer consists of M strip rows arranged in parallel. Electrode composition (one row electrode is regarded as a row), the second conductive electrode layer is composed of N strip-shaped column ele...

Abstract

The invention discloses a method for display driving of any region of a smectic-phase liquid crystal screen. The method comprises: updating a rectangular region where a region is according to an image, dividing all rows into drive rows and non-drive rows and diving all lines into drive lines and non-drive lines; carrying out polishing initialization of the rectangular region; and performing scan driving of all the drive rows one by one, wherein during the process of scan driving of each drive row, a pair of high-frequency high-voltage pulses which are only oppositely phased are loaded on a drive row which is subjected to scan driving and a drive line which is corresponding to pixel points that are located on the drive row subjected to scan driving and within the rectangular region and need to be driven, and a pair of high-frequency low-voltage pulses which are only oppositely phased are loaded on the other rows and the other lines. The invention makes it possible to perform, on a smectic-phase liquid crystal screen, display driving of a rectangular region where any region with an image to be updated is located, without the need of full-screen display driving, thereby improving the refreshing speed and reducing the power consumption.

Description

technical field [0001] The invention relates to a display driving method applied to a smectic phase liquid crystal screen, in particular to a display driving method for a local area on the smectic phase liquid crystal screen that needs image updating. Background technique [0002] Smectic phase liquid crystal screen is one of the most promising flat panel display devices at present. With its unique film surface characteristics and reflective display principle, it has the advantages of simple structure, wide viewing angle, stable picture, real safety and environmental protection, power saving, and long-term memory. It has many advantages such as function and user fatigue, and is in a leading position in the ranks of monitors. [0003] At present, there are various display driving methods for smectic liquid crystal screens, such as progressive scan drive, line skip scan drive, dynamic scan drive, bidirectional scan drive, etc., although these display drive methods can make the...
