Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] The line skip scanning driving method of the present invention is designed for a smectic liquid crystal display. Such as figure 1 and figure 2 As shown, the smectic liquid crystal display screen 1 includes a first base layer 11 and a second base layer 12, and the materials of the first base layer 11 and the second base layer 12 can be glass or plastic. Between the first matrix layer 11 and the second matrix layer 12, there is a mixed layer 13 formed by mixing smectic liquid crystals and additives, that is, by Figure 5 Smectic liquid crystal molecules 131 shown in are mixed with additive molecules 132 . The smectic liquid crystal is a class A smectic liquid crystal (Smectic-A) organic compound, such as a compound with a silicon group, tetracyanotetraoctylbiphenyl, decyl tetraacetate tetracyanobiphenyl, and the like. The additives are compounds with conduc...

Abstract

The invention discloses a line jump scanning drive method for a smectic state liquid crystal display screen, which comprises the following steps of: reading data of each line in turn by taking line as a unit, filtering the data of the line at the same time, and judging whether the line has display content, if so, storing a starting address corresponding to the data of the line in an address memory; storing a filter trailing flag after the last starting address; reading each starting address in turn; while reading one starting address, reading the data of the line corresponding to the starting address from an image memory, outputting a corresponding pulse on a strip electrode of a first conducting electrode layer corresponding to the line, and outputting the corresponding pulse according to the read data of the line on each strip electrode of a second conducting electrode layer; and when the filter tailing flag is read, stopping outputting the pulses. The line jump scanning drive method is suitable for the smectic state liquid crystal display screen, and can effectively improve the image refresh rate of the display screen.

Description

technical field [0001] The invention relates to a scanning driving method, in particular to a line skipping scanning driving method for improving the image refresh rate of a smectic liquid crystal display screen. Background technique [0002] Liquid crystal display is one of the most promising flat panel display devices at present. Traditional liquid crystal displays are passive displays, that is, transmissive displays, which can only be displayed under the condition of an external backlight, but the power consumption of the backlight is the liquid crystal itself. More than hundreds of times the power consumption, very energy-consuming. With the development of liquid crystal technology, various liquid crystal materials emerge in an endless stream, among which the reflective liquid crystal that does not require a backlight has an absolute advantage due to its low power consumption characteristics. The smectic liquid crystal display in the Chinese utility model patent "a disp...
