Embodiment one
With reference to Fig. 1, a kind of display control method of fast response time, including step：
After obtaining the image to be displayed of LCDs, according to signal decomposition look-up table, image to be displayed is decomposed into into first and is shown
Diagram picture and the second display image, specially：After obtaining the image to be displayed of LCDs, according to signal decomposition look-up table,
Each pixel is searched in obtaining image to be displayed in the first liquid crystal panel and the corresponding grey decision-making of the second liquid crystal panel, so as to will
Image to be displayed is decomposed into the first display image and the second display image.It is this step by the GTG display matrix of image to be displayed
It is converted into two GTG display matrixes, respectively the first display image and the second display image.
First display image and the second display image are respectively correspondingly sent to into the first liquid crystal panel and the second liquid crystal surface
Plate synchronizes display.Simultaneous display result is：L=A*B, wherein L represent grey decision-making of the pixel in image to be displayed, A and
B represents grey decision-making of the pixel in the first display image and the second display image respectively.
In the present embodiment, as shown in figure 3, the pixel of the pixel of the first liquid crystal panel and the second liquid crystal panel is in space
On align one by one, the wherein string pixel that the first liquid crystal panel and the second liquid crystal panel are illustrate only in Fig. 3 aligns pass one by one
Every string pixel of system, actually the first liquid crystal panel and the second liquid crystal panel aligns one by one.If liquid crystal display screen point
Resolution is 1366*768, and the resolution of image to be displayed is 1366*768, then the first display image A and second after decomposing shows
Image B, by 1366*768 pixel composition, horizontal direction N=1366 pixel arrangement, vertical direction M=768 pixel row
Row.
In this example, signal decomposition look-up table to set up process as follows：
Each pixel of the first liquid crystal panel and the second liquid crystal panel is tested respectively to any two grey decision-making between 0-255
GTG Ta（N1, m1）With T b（N1, m1）；Wherein n1 and n2 is initial GTG, and m1 and m2 is target gray scale, and this four
The span of individual parameter is（0--255）Or 2 systems（0 to 11111111）.
After obtaining the most short GTG of the first liquid crystal panel and the second liquid crystal panel respectively, both are added into work
For judgment threshold；
For each grey decision-making between 0-255, according to judgment threshold and default grey scale transformation condition, correspondence after its decomposition is calculated
First decomposition grey decision-making and second decompose grey decision-making；
The first each grey decision-making corresponding decomposition grey decision-making and the second decomposition grey decision-making are associated into storage, signal is generated
Decompose look-up table.
Wherein, for each grey decision-making between 0-255, according to judgment threshold and default grey scale transformation condition, calculate which
After decomposition it is corresponding first decompose grey decision-making and second decompose grey decision-making the step of, which is specially：
The span of two design factor j of setting and k, j and k is 0-255, for each grey decision-making between 0-255, according under
Formula carries out the lookup of binary numeration system and calculates to j and k, when result of calculation is equal to judgment threshold, design factor j and k is made
After decomposing for the grey decision-making, corresponding first decomposes grey decision-making and the second decomposition grey decision-making：
f(j,k) = | j* k/(11111111)2-L(m)/1111111111111111|
In above formula, f (j, k) represents result of calculation, and L (m) represents grey decision-making to be decomposed.
The looked-up sequence of design factor j and k is as follows：J proceeds by lookup from 0, for each value of j, k from 0 to
11111111 are sequentially searched, and are circulated successively., from the beginning of 0, k is from 0 to 11111111 for j first（2 system numeral systems）Begin look for,
After k searches a circulation, j+1 is made, the circulation searching of k is then proceeded to, then is made j+1, until j=11111111.It is right in search procedure
Each result of calculation f (j, k), is matched with judgment threshold, if equal to judgment threshold, then current j and k is the GTG
It is worth corresponding decomposition grey decision-making, now, after the grey decision-making k superpositions of the grey decision-making j and the second liquid crystal panel of the first liquid crystal panel, folds
Plus show result closest to grey decision-making L (m) to be decomposed.The grey decision-making of certain pixel of such as original image is 100, to be shown
The grey decision-making of the pixel of image is L0=100000, if directly displayed, gray scale variation is larger, and response time is long,
Easily there is hangover situation, after being decomposed by this method, the grey decision-making for the pixel being obtained in the first liquid crystal panel is L1=
10000, it is L2=100 in the grey decision-making of the second liquid crystal panel, finally realizes the brightness output of input picture.
Each pixel of image to be displayed is carried out after above-mentioned decomposition, the first display image and second is finally obtained and is shown
The Overlapping display result of image, the first display image and the second display image closest to image to be displayed, and, through decomposition
Afterwards, the GTG of each pixel of the first display image and the second display image realizes optimization, greatly carries
The response speed of liquid crystal display screen is risen.Because current data processing speed is quite quick, therefore the calculating catabolic process of this method
Impact to response speed is negligible.The present embodiment is by using two panels liquid crystal panel by finding minimum liquid crystal upset
Time GTG, realizes most short response time after image overlay, reaches the problem for mitigating streaking.
It is more than that the preferable enforcement to the present invention is illustrated, but the invention is not limited to the enforcement
Example, those of ordinary skill in the art on the premise of without prejudice to spirit of the invention can also be made a variety of equivalent variations or replace
Change, the modification of these equivalents or replacement are all contained in the application claim limited range.
