It can be the grayscale of present frame picture.
In addition, the First Eigenvalue of former frame picture includes the characteristic value of each pixel in picture, the of present frame picture
Two characteristic values include the characteristic value of each pixel in picture；The grayscale of former frame picture includes each pixel in former frame picture
Grayscale value, the grayscale of present frame picture includes the grayscale value of each pixel of present frame picture.
In one embodiment, the First Eigenvalue of former frame picture and the Second Eigenvalue of present frame picture, packet are obtained
It includes:
The grayscale of each pixel of former frame picture is obtained, and is obtained in present frame picture each of with former frame picture
The grayscale of the identical pixel of location of pixels.
In one embodiment, each location of pixels phase of the position of each pixel of former frame picture and present frame picture
Corresponding, the grayscale of acquisition is respectively the grayscale value of corresponding same position pixel.
Step S202, judges whether the First Eigenvalue and the Second Eigenvalue meet preset condition.
In one embodiment, by the ash of the grayscale of each pixel of former frame picture and each pixel of present frame picture
Rank is compared, and obtains the first comparison result；Judge whether picture shown by display device is quiet by the first comparison result
State picture；The grayscale of the pixel of present frame picture same row is compared, the second comparison result is obtained, is sentenced according to the second comparison result
Whether disconnected present frame picture is target picture.
Wherein, preset condition includes: the difference of identical as Second Eigenvalue or both the characteristic value of the First Eigenvalue default poor
It is worth in range, preset difference value can be set according to display panel types；Pixel gray level in Second Eigenvalue in each column is
For grey scale between no identical or each column different pixels in preset gray scale difference range, preset gray scale difference can be according to aobvious
The resolution sizes or structure type for showing panel are set.
In one embodiment, judge whether the First Eigenvalue and the Second Eigenvalue meet preset condition, wrap
It includes:
The former frame picture is compared with the grayscale of the identical pixel in position in the present frame picture, judgement is worked as
Whether the picture of preceding display is tableaux；
The grayscale for being located at the pixel of same row in the present frame picture is compared, judges that the present frame picture is
No is target picture.
In one embodiment, if the first comparison result are as follows: former frame picture picture identical with position in present frame picture
The grayscale of element is identical or grayscale difference is within 5 grayscale, then determines the picture currently shown for tableaux；If second compares
As a result are as follows: the grayscale in present frame picture between the pixel of same row is identical or grayscale difference is within 5 grayscale, then sentences
Settled previous frame picture is target picture；If the picture of display is tableaux, present frame picture is target picture, then illustrates first
Characteristic value and Second Eigenvalue meet preset condition.
Wherein, the tableaux is the picture of generating state variation of not changing with time, in order to extend key
When the play time of frame picture, frequently with tableaux.
It should be noted that grayscale difference can be configured according to actual needs, it is not limited to which 5 grayscale are being divided
When resolution is higher, it is also possible to 8 or 10 grayscale, does not do specific restriction herein.
Step S203 determines that the present frame picture is target picture if meeting preset condition, is exporting the target
When picture, the timing of the signal of scan line and data line output is controlled.
In one embodiment, if the Second Eigenvalue of the First Eigenvalue of former frame picture and present frame picture meets in advance
If condition, then determine present frame picture for target picture；Target picture includes white picture, grey menu or pure color picture；Preceding
The broadcasting of one frame picture terminates, and obtains the image data of present frame picture, exports present frame picture, i.e. target picture.
The output signal is the scanning signal for controlling grid line, the control letter of the driving signal output timing of data line
Number；When exporting target picture, output control signal stops the scanning signal of output scan line and the driving letter of data line
Number, the voltage of data line is maintained into current value, and the polarity of voltage does not invert；So that pixel capacitance remains current
Voltage is constant, without the charge and discharge of capacitor, reduces the consumption of power.
It should be noted that then opening row crystalline substance when scanning signal is transmitted on a certain horizontal scanning line of display panel
Body pipe, while output drive signal, to data line, the voltage swing of driving signal changes, and the polarity of pixel can be made to occur anti-
Turn, it is positive polarity that voltage, which is greater than common electrode, and being less than common electrode is negative polarity, exports different voltage driving pixel capacitances and is filled
Electric discharge.It is tableaux detecting shown picture, will export is target picture, then in the same of output target picture
When, temporarily output drive signal, control grid electrode drive module do not export scanning signal temporarily, keep control source drive module
The current output voltage of source drive module makes output voltage that polarity reversion not occur, and pixel capacitance does not generate charge and discharge, reduces
The power consumption of display panel.
In one embodiment, the display device further includes grid electrode drive module and source drive module, the grid
Drive module is connect with the multi-strip scanning line, and the source drive module is connect with the multiple data lines；
If meeting preset condition, determine that the present frame picture is target picture, when exporting the target picture, control
The timing of scan line processed and the signal of data line output, comprising:
If the former frame picture is identical as the grayscale of the identical pixel in position in the present frame picture or grayscale difference
Within the scope of the first preset difference value, then determine the picture currently shown for tableaux；
If the grayscale in the present frame picture positioned at the pixel of same row is identical or grayscale difference is in the second preset difference value
In range, then determine that the present frame picture is target picture；
If the picture currently shown is tableaux, the present frame picture is target picture, then described in the output
When target picture, the grid electrode drive module and the source drive module are output control signals to, is driven with controlling the grid
Dynamic model block stops output scanning signal, controls the source drive module and stops output drive signal.
In one embodiment, the first preset difference value and the second preset difference value can be according to the specific pictures of being shown, aobvious
The type and practical application scene for showing panel are set, and can also be set according to the feature of tableaux and target picture
It is fixed.
The picture currently shown includes former frame picture and present frame picture, if the picture currently shown is static draws
Face, and present frame picture is target picture, then while exporting target picture, output control signal controls gate driving mould
The output timing of block scan signal and source drive module driving signal temporarily ceases output scanning signal and driving signal,
Or control grid electrode drive module and source drive module export in sequence.
In one embodiment, if meeting preset condition, determine that the present frame picture is target picture, in output institute
When stating target picture, the timing of the signal of scan line and data line output is controlled, comprising:
When exporting the target picture, first control signal is exported to the grid electrode drive module, controls the grid
