There is a plurality of valid pixel row AP11、AP12(only illustrating two of which).Additionally, in order to transmit image smoothly, the first water can be set
White area HB out of the void1And the first vertical blank white area VB1The time transmitting data for switching is stopped as image when to transmit.The
One horizontal blank white area HB1Corresponding most horizontal blank pixel column HB11、HB12(only illustrating two of which), as transmitting valid pixel
The switching of row is used.First vertical blank white area VB1Corresponding most vertical blank pixel column VB11、VB12(only illustrating two of which),
Switching as different images is used.
Refer to Fig. 2, it is known that can be with one first clock signal PCLK in technology1Transmit image Fr, the first clock signal
PCLK1Comprise at least one first valid pixel time interval A1, at least one first horizontal blank time interval H1And one first hang down
Straight blank time interval V1.In the first valid pixel time interval A1The data of valid pixel row can be transmitted, and transmitting one
After valid pixel row, in the first horizontal blank time interval H1Do not transmit data, transmit next valid pixel row the most again
Data.As a example by Fig. 2, can be first at the first valid pixel time interval A1Transmit valid pixel row A11Data, then first
Horizontal blank time interval H1Do not transmit data, then then at the first valid pixel time interval A1Transmit next valid pixel
Row A12Data, other valid pixels row also can transmit in the same way.And after all valid pixels row have all transmitted, meeting
Pause the first vertical blanking time interval V1Do not transmit data, be then switched to next image.Therefore, each first valid pixel
Time interval A1Corresponding amount of pixels is each first valid pixel row (AP11、AP12...) amount of pixels, each first horizontal blank

Vertical blank interval is just opened.It is to say, should be that picture first shows that first image data is (the most aforesaid effectively in sequential
Pixel range), certain time point in first vertical blank interval opens backlight afterwards, ties in first vertical blank interval
The time point of bundle turns off backlight, then second image of display.Certain time point in second vertical blank interval is beaten afterwards
Opening backlight, the time point terminated in second vertical blank interval turns off backlight, and the rest may be inferred;So when backlight is opened
Wait, it is simply that the when that human eye experiencing image.Because the characteristic of liquid crystal itself, transfer between different pieces of information (such as from A data to
B data), the current potential of signal needs one section and climbs or complete fall time, so the image that human eye is experienced is A number in fact
According to the result mixing out with certain ratio of B data, optimal ratio is A=0%, B=100%, i.e. human eye will not be experienced
The image of front data.But because the relation of liquid crystal characteristic, it is impossible to so, this proportionate relationship is exactly so-called crosstalk
(cross-talk), therefore, if transmitting summation time (the aforementioned first clock signal PCLK of valid pixel1In all first have
Effect picture point time interval A1 and all first horizontal blank time interval H1Temporal summation) oversize, just may produce image
Crosstalk.

Fig. 4 is for only for ease of the image output action explained in Fig. 5, and non-limiting must there is such image data form
It it is just the scope of the present invention.Join Fig. 4 Yu Fig. 5 the most alternately more to understand present disclosure.
As it is shown in figure 5, the second clock signal PCLK2Comprise at least one second valid pixel time interval A2, at least one second
Horizontal blank time interval H2And one second vertical blanking time interval V2.Second valid pixel time interval A2, the second level
Blank time interval H2And the second vertical blanking time interval V2Effect and the first valid pixel time interval shown in Fig. 2
A1, the first horizontal blank time interval H1And the first vertical blanking time interval V1Effect identical.Each second valid pixel
Time interval A2Corresponding amount of pixels is each second valid pixel row (AP21、AP22...) amount of pixels, each second horizontal blank
White time interval H2Corresponding amount of pixels is each second horizontal blank pixel column (HB21、HB22...) amount of pixels, and second hang down
Straight blank time interval V2Corresponding amount of pixels is whole second vertical blank pixel column (VB21、VB22...) amount of pixels total
With.
Second clock signal PCLK2The second valid pixel time interval A2With the first clock signal PCLK1First effective
Picture point time interval A1Identical.But, the second clock signal PCLK2The second horizontal blank time interval H2Less than the first seasonal pulse
Signal PCLK1The first horizontal blank time interval H1.The most therefore, the second horizontal blank white area HB in Fig. 42In each second
Horizontal blank pixel column HB21、HB22Pixel count can be less than the first horizontal blank white area HB in Fig. 11In each first horizontal blank
White pixel row HB11、HB12Pixel count.
In one embodiment, the first effective pixel region AP1Pixel count, the first horizontal blank white area HB1Pixel count and
One vertical blank white area VB1The summation (the referred to as first pixel summation) of pixel count, with the second effective pixel region AP2Pixel count,
Two horizontal blank white area HB2Pixel count and the second vertical blank white area VB2The summation (the second pixel summation) of pixel count identical.
Therefore, the second horizontal blank white area HB2Compared to the first horizontal blank white area HB1Pixel count (the horizontal blank picture referred to as reduced reduced
Element) the second vertical blank white area VB can be moved2Compensate.To have embodiment describes how to determine the second vertical blank white area in detail below
The columns of the second vertical blank row.
By the way of Fig. 4 Fig. 5, due to the second valid pixel time interval A2With the first clock signal PCLK1First have
Effect picture point time interval A1Identical, but the second horizontal blank time interval H2Less than the first horizontal blank time interval H1, therefore make
With the second clock signal PCLK2Transmit temporal summation (all A of valid pixel2Add H2) the first clock signal PCLK can be used by ratio1
Transmit temporal summation (all A of valid pixel1Add H1) come few, therefore can improve the problem in known technology.
In some embodiments, it may be possible to have the horizontal blank pixel that minimizing cannot be fully allocated to the second vertical blank picture
The situation of element row.For example, if there being 1000 pixels to be intended to be assigned to the second vertical blank white area and each second vertical blank picture
The pixel count of element row is 100, then can increase by 10 row the second vertical blank pixel columns to compensate the horizontal blank pixel of minimizing is
1000.But, if there being 1020 pixels to be intended to be assigned to the second vertical blank white area and the pixel of each second vertical blank pixel column
Number is 100, then cannot distribute to the second vertical blank pixel column by complete for the horizontal blank pixel of minimizing and have remainder 20
Exist.Therefore the present invention more provides following content for such situation and processes.
Fig. 7 and Fig. 8 depicts and how to adjust the exemplary of columns of vertical blank pixel column according to residual pixel number and show
It is intended to.As it is shown in fig. 7, the pixel count that pixel count is the 1920, first horizontal blank white area pixel column of the first valid pixel row is
280, the pixel columns of the first valid pixel row is 1080, and the pixel columns of the first vertical blank white area pixel column is 45, therefore the
One pixel summation is (1920+280) x (1080+45)=2200x1125=2475000.If the pixel count of the second valid pixel row is still
Be 1920 and its pixel columns is still 1080, and the pixel count of the second horizontal blank white area pixel column is assumed to be 50, then second is effective
Pixel region AP2Pixel count and the second horizontal blank white area HB2The summation of pixel count be (1920+50) x1080=2127600.Cause
This pixel count having 247500-2127600=347400 is to be allocated to the second vertical blank white area VB2.In this example, second hangs down
The pixel count of straight clear area pixel column is the pixel count pixel plus the second horizontal blank white area pixel column of the second valid pixel row
Number, is therefore 1970.Therefore, if by the horizontal blank white area pixel that reduces divided by the pixel count of the second vertical blank white area pixel column:
347400/1970, then can obtain integer 176 and remainder 680.This integer 176 is the pixel of the second vertical blank white area pixel column
Number, remainder 680 is residual pixel number H_Red.
Fig. 8 depicts according to the schematic diagram processing image with the image treatment method of the present invention, and each parameter of its image is such as
Data shown in Fig. 7.According to the description of Fig. 7, when processing image 1, the pixel columns of the second vertical blank white area pixel column is 176
And remainder 680, the buffer 305 that this numerical value 680 can be kept in Fig. 3 is as residual pixel number H_Red, but 680 less than the
The pixel count 1970 of two vertical blank white area pixel columns, does not the most increase the columns of the second vertical blank white area pixel column.And processing
During image 2, still can obtain 176 the second vertical blank white area pixel columns and the remainder of 680, now residual pixel number H_Red meeting
Being added to buffer 305, therefore residual pixel number H_Red is 1360, but 1360 still less than the second vertical blank white area pixel column
Pixel count 1970, the most do not increase the columns of the second vertical blank white area pixel column.But when processing image 3,176 still can be obtained
Bar the second vertical blank white area pixel column and the remainder of 680, now residual pixel number H_Red can be added to 2040, exceedes
The pixel count 1970 of the second vertical blank white area pixel column, therefore the second vertical blank white area pixel column number of image 3 can be set
Become 176+1, and the pixel count 1970 that residual pixel number H_Red can deduct the second vertical blank white area pixel column becomes 70.Class according to this
Heap, the second vertical blank white area pixel column columns of image 4 is 176 and residual pixel number H_Red is 750, and the second of image 5 is vertical
Clear area pixel column columns is 176 and residual pixel number H_Red is 1430, but during to image 6, residual pixel number H_Red is
1430+680, more than the pixel count 1970 of the second vertical blank white area pixel column, therefore the second vertical blank white area pixel column of image 6
Number is configured to 176+1 once again, and residual pixel number H_Red can deduct the pixel count 1970 of the second vertical blank white area pixel column
Become 140.But after residual pixel number also can be allowed to be accumulate to the number more than X bar the second vertical blank pixel column, (X is more than 1
Positive integer), once increase X bar the second vertical blank pixel column.Also please noting that, the buffer of Fig. 3 can be located at any position, also may be used
It is integrated into controller 301 or buffer 303.
Therefore, the embodiment of Fig. 7 and Fig. 8 can be considered the row determining the second vertical blank white area pixel column according to following equation
Number:
Hd/Vt=M+Q
Wherein HdThe first clock signal PCLK for single cycle2Pixels corresponding to all first valid pixels row
Amount (the i.e. first effective pixel region AP1Amount of pixels), amount of pixels (the i.e. first water that all first horizontal blank time intervals are corresponding
White area HB out of the void1Amount of pixels) and amount of pixels (the i.e. first vertical blank white area HB corresponding to the first vertical blanking time interval1's
Amount of pixels) deduct the second clock signal PCLK of single cycle2Amount of pixels corresponding to all second valid pixels row (i.e.
Second effective pixel region AP2Amount of pixels) and all second horizontal blank time intervals (the i.e. second horizontal blank white area HB2Picture
Element amount) corresponding amount of pixels.VtFor this second vertical blank pixel column bag each that this second vertical blanking time interval is corresponding
The pixel count (being such as 1970 in Fig. 7 embodiment) contained, M is Hd/VtInteger, and Q is Hd/VtRemainder.If M more than or
During equal to 1, then this M arranging the number as this second vertical blank pixel column, if Q is not zero, then the value adding up this Q produces
One residual pixel value also stores this residual pixel value.
And, in time receiving this image with this first seasonal pulse and export this image with this second clock signal every time, will be every
The value of this Q once is added to this residual pixel value.If this residual pixel value is less than this VtValue then this M is arranged as this
The number (image 1,2,4,5 in such as Fig. 8) of two vertical blank pixel columns.If this residual pixel value exceedes this VtValue, then
The number of this second vertical blank pixel column is increased N row, and deducts this V from this residual pixel valuetIt is multiplied by the value of this N, wherein N
For the positive integer (image 3,6 in such as Fig. 8) more than or equal to 1.The first pixel summation in this type of embodiment, before adjustment
Will not be identical with the first pixel summation after adjusting, but its difference is smaller than a predetermined value.Therefore the sequential transmitted image is not
Too much influence can be caused.
According to aforesaid embodiment, flow chart as shown in Figure 9 can be obtained, it comprises the following step:
Step 901
With one first clock signal PCLK1Receive an image, this first clock signal PCLK1Tool at least one first effective picture
Element time interval A1, at least one first horizontal blank time interval H1And one first vertical blanking time interval V1。
Step 903
With one second clock signal PCLK2Export this image, this second clock signal PCLK2Tool at least one second effective picture
Element time interval A2, at least one second horizontal blank time interval H2And one second vertical blanking time interval V2。
Wherein the first valid pixel time interval A1And the second valid pixel time interval A2Corresponding pixel count is identical.
Second horizontal blank time interval H2Corresponding pixel count is less than the first horizontal blank time zone H1Between corresponding pixel count, and the
Two vertical blanking time district H2Between corresponding pixel count more than this first vertical blanking time interval H1Corresponding pixel count.
Other detailed technical characteristics have been described in previous embodiment, therefore repeat no more in this.
By shortening horizontal blank time interval, so that the climbing or decline and carry of signal potential between aforementioned different pieces of information
Early occur, so when backlight is opened once again when, the meeting that human eye is experienced is rear data (the most aforesaid B number that comparison is many
According to) and fewer front data (the most aforesaid A data), namely reduce crosstalk.Therefore, permissible by such mode
