Embodiment Construction

[0032] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] Such as Figure 4 Shown, the present invention comprises the following steps:

[0034] 1) Using a subfield arrangement algorithm to achieve grayscale classification and generate a grayscale subfield arrangement table 401;

[0035] 2) Generate a grayscale driving waveform 402 through the grayscale subfield arrangement table;

[0036] 3) Applying the gray-scale drive waveform to the current row electrode and column electrode to be driven on the smectic liquid crystal display to drive the liquid crystal molecules in the smectic liquid crystal display to stay in different alignment states to show the Different gray scales 403 of the image are displayed.

[0037] In practical applications, the data of the image to be displayed on the display screen is sequentially stored in an image memory in row units, and each data is assigned an address. Take a smectic liqui...

Abstract

The invention discloses a method for realizing the gray scale of a smectic-phase liquid crystal display. The method comprises the following steps: 1) using a sub-field arrangement algorithm to realize the classification of gray scales and produce a gray scale sub-field arrangement table; 2) producing a drive waveform with the gray scale based on the gray scale sub-field arrangement table; and 3) applying the drive waveform with the gray scale to the currently row electrodes and column electrodes to be driven on the smectic-phase liquid crystal display to drive the liquid crystal molecules in the smectic-phase liquid crystal display to stay in different arrangement states so as to display the different gray scales of the image to be displayed. The invention can realize m+1 numbered gray scale states from 0 to m, wherein m is greater than or equal to 1 and is less than or equal to 511. The method for realizing the gray scale of the smectic-phase liquid crystal display successfully realizes the display of an image with the gray scale on the smectic-phase liquid crystal display.

Description

technical field [0001] The invention relates to a smectic liquid crystal display technology, in particular to a method for realizing the gray scale of a smectic liquid crystal display. 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 circuit" (patent...
