Sub-pixel look-up table determines corresponding first grayscale of different input grayscale and the second grayscale.K point, it is assumed that K point is located at A point, B
The centre of point, D point and E point, corresponding first grayscale of current input grayscale of the sub-pixel of K point and the second grayscale, can be with
Interpolation fortune is carried out using corresponding first grayscale of current gray in the look-up table of A point, B point, D point and E point and the second grayscale
It calculates, so that corresponding first grayscale of current input grayscale and the second grayscale of the sub-pixel of K point are obtained, for example, can be by A
Point, B point, D point and corresponding first grayscale of E point current gray and the second grayscale are averaged respectively, which is made
For corresponding first grayscale of current input grayscale and the second grayscale of the sub-pixel of K point.The mode of other points is analogized, herein not
It repeats again.
S204, operation of being made up the difference according to the first grayscale and the second grayscale progress time and space.
Specifically, from above-mentioned steps it is found that needing when determining the first grayscale and the second grayscale of sub-pixel to positive value ash
Positive polarity grayscale in rank table and negative polarity grayscale carry out offset to obtain the first grayscale and the second grayscale, the first grayscale with
And second grayscale range may overflow positive value grayscale table range or lower than positive value grayscale table range.Therefore, it is necessary to
Time and space are carried out to liquid crystal display device to make up the difference operation, compensate this problem.
Time makes up the difference (FRC) operation to generate more grayscale effects by temporal mixed color effect.For example, original ash
Order range is 511 i.e. 9bits grayscale, increases FRC function, by temporal mixed color effect, can produce grey-scale range is
The 2048 i.e. effect of 11bits grayscale.The principle of work and power is as follows: in the time of continuous 4 picture frames, adjustment is black and white out
Existing time scale, available 1/4 ash of viewer, 2/4 ash and 3/4 these grey intermediate grayscale display effects.Although with regard to single frame
For be 9bits grayscale amount, but liquid crystal display device, in dynamic refresh data, viewer perceives out 11bits grayscale amount.
(Dithering) operation make up the difference to generate more grayscale effects by mixed color effect spatially in space.With phase
For adjacent 4 pixel spaces, adjustment black-and-white two color spatial position arrangement ratio, available 1/4 ash of viewer, 2/4 ash and 3/4
These grey intermediate grayscale display effects.

It is intended to.In 8 sub-pixels, wherein four corresponding first grayscale of sub-pixel input grayscale, remaining four sub-pixel input grayscale
Corresponding second grayscale.Wherein, corresponding four the first grayscale of four sub-pixels meet at least one grayscale and add one in space,
In the time, meets at least one grayscale and add one；Corresponding four the second grayscale of four sub-pixels meet at least in space
One grayscale adds one, in the time, meets at least one grayscale and adds one.For example, it is assumed that the first grayscale value of four sub-pixels is
100, then the first grayscale value of four sub-pixel at least one sub-pixels is 101 in space, in the time, i.e., in nth frame
In~the N+4 frame cycle of images, the first grayscale value of at least one sub-pixel is 101, and may finally obtain grayscale value is
100.25 the first grayscale；Assuming that the second grayscale value of four sub-pixels is 4, then in space four sub-pixels at least one
First grayscale value of sub-pixel is 5, in the time, i.e., in nth frame~N+4 frame cycle of images, and at least one sub-pixel
The first grayscale value be 5, may finally obtain grayscale value be 4.25 the second grayscale.
It is made up the difference operation, grey-scale range can be expanded by time and space, the time, which makes up the difference, to improve space and make up the difference resolution
Decline, space make up the difference improve the time make up the difference frame color range loss, the two perfection collocation, have complementary functions, to blend optimal ash
Rank effect, and grayscale transition is naturally smooth.
S205, corresponding positive polarity data voltage and negative polarity number are obtained according to the first grayscale and the second grayscale respectively
According to voltage.
Specifically, using the first grayscale and the second grayscale of each sub-pixel point determined in above-mentioned steps, pass through grayscale
The mapping relations of value and gamma curve, can determine the corresponding positive polarity data voltage of the first grayscale and the second grayscale pair
The negative polarity data voltage answered.The positive polarity data voltage subtract the positive polarity pixel voltage that Feedthrough voltage obtains with
And negative polarity data voltage subtracts the negative polarity pixel voltage that Feedthrough voltage obtains to compare Vcom symmetrical.
S206, output cathode data voltage and negative polarity data voltage are to picture element matrix 104.
