Column pulse dual-side driving method for smectic liquid crystal display screen

Abstract

The invention discloses a column pulse dual-side driving method for a smectic liquid crystal display screen, comprising the following steps: 1) initializing a smectic liquid crystal display screen; and 2) respectively carrying out row-column driving on the top half screen and the bottom half screen according to the respective set scanning driving way, thereby leading the top half screen and the bottom half screen to display the respective images; simultaneously respectively carrying out scanning driving on one row electrode of the top half screen and one row electrode of the bottom half screen during the row-column driving process of the top half screen and the bottom half screen; respectively applying the corresponding column pulse to each column electrode on the top half screen according to the image displayed by the row which corresponds to the row electrode while carrying out the scanning driving on one row electrode on the top half screen; and respectively applying the corresponding column pulse to each column electrode on the lower half screen according to the image displayed by the row which corresponds to the row electrode while carrying out the scanning driving on one row electrode on the lower half screen. The adoption of the column pulse dual-side driving method for the smectic liquid crystal display screen can improve the image refresh rate, and the display screen structure and the method are particularly suitable for the high-definition image display.

Description

technical field [0001] The invention relates to a driving method of a display screen, in particular to a column pulse bilateral driving method applied to 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 display control circui...

Problems solved by technology

However, in order to meet the improvement of people's requirements for image display, the resolution of the display screen has been continuously improved, and the corresponding amount of image data has also increased, and all column pulses must be provided from the unilateral column pulse drive circuit. When scanning a row, the column pulse drive circuit is required to provide a set of column pulses. Therefore, for a high-resolution smectic liquid crystal display, the time required to refresh a high-resolution image using the column pulse unilateral drive method will be greatly reduced. Increase
