Problems solved by technology

However, it can be seen from actual implementation that this method cannot completely clear the previous image, and sometimes even the displayed new image will change back to the original previous image, which will inevitably affect the speed of image change, and Visual effects are greatly reduced

Embodiment Construction

[0026] The method for removing the image traces of the smectic liquid crystal display screen of the present invention is designed for the smectic liquid crystal display screen. Such as figure 1 with 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 base layer 11 and the second base layer 12 is provided a mixed layer 13 composed of a mixture of smectic liquid crystals and additives, namely Figure 5 The smectic liquid crystal molecules 131 shown in FIG. 1 are mixed with additive molecules 132. The smectic liquid crystal is a type A smectic liquid crystal (Smectic-A) organic compound, such as a compound with a silicon group, tetracyanotetraoctylbiphenyl, decyl tetraacetate tetracyanobiphenyl, and the like. Additives are compounds with conductive properties, such as compounds containing conduct...

Abstract

The invention discloses a method for getting rid of smectic state LCD image traces, comprising: respectively loading a pair of low-frequency high-voltage negative and positive pulses with same frequency amplitude and reverse phases onto M strip electrodes of a first electric conduction electrode layer and N strip electrodes of a second electric conduction electrode layer; after the first setting time, stopping loading; respectively loading a pair of high-frequency high-voltage negative and positive pulses with same frequency amplitude and reverse phases onto M strip electrodes of the first electric conduction electrode layer and N strip electrodes of the second electric conduction electrode layer; after the second setting time, stopping loading; repeating the above two steps for at least one time; respectively loading a pair of low-frequency high-voltage negative and positive pulses with same frequency amplitude and reverse phases onto M strip electrodes of the first electric conduction electrode layer and N strip electrodes of the second electric conduction electrode layer; and after the first setting time, stopping loading. The invention can get rid of the smectic state LCD image traces in an extremely short time so as to quickly display the next image.

Description

Technical field [0001] The invention relates to a method for removing image traces of a liquid crystal display screen, in particular to a method for removing image traces of a smectic liquid crystal display screen. Background technique [0002] Most of the traditional liquid crystal displays are transmissive. The image display of this traditional transmissive liquid crystal display is realized by using the optical phase change characteristics of liquid crystals under the action of an electric field, that is, when the electric field is energized, the The arrangement of the liquid crystal molecules is that the liquid crystal molecules form a phase difference of 90 degrees, and the light passes through the liquid crystal layer; when the electric field is not energized, the arrangement of the liquid crystal molecules returns to the original state, and the liquid crystal molecules form a phase difference of 0 degrees or 180 degrees. Light is blocked from passing through the liquid cry...
