The brightness value of white is calculated, Date Conversion Unit before this is converted to RGBW signals without by rgb signal.
S62, calculate the display ratio of each color in preset time period.
In one embodiment of the invention, can be to all colours pair after brightness value corresponding to each color is obtained
The brightness value summation answered, calculates luminance total value.Then, brightness value corresponding to each color divided by luminance total value, calculate every
Kind color shows ratio accordingly.Continue upper example, it is assumed that the luminance total value of all sub-pixels is T in preset time period, then T=TR
+TG+TB+TW.So, red display ratio is RR=TR/T, and green display ratio is RG=TG/T, blue display ratio

In order to improve the accuracy of sensing, in another embodiment of the present invention, it is that two predetermined threshold values, which can be set,
Two threshold values and the 3rd threshold value.Second Threshold is more than 0, is more than or equal to 0 less than or equal to 1, the 3rd threshold value, less than 1, and Second Threshold is big
In the 3rd threshold value.Specifically, can respectively by the display ratio of tri- kinds of colors of RGB compared with Second Threshold and the 3rd threshold value,
The second comparative result set is obtained, then the sensing modes according to corresponding to determining the second comparative result set.As an example it is assumed that
Second Threshold is R2, and the 3rd threshold value is R3, is respectively RR by the display ratio of red, the display ratio of green is RG, blueness
Display ratio is RB compared with R2, R3.If RR is more than or equal to R2, SR=1 is exported, represents to need to accelerate red sub- picture
The sensing of element；If RR is less than R2, and is more than or equal to R3, then SR=2 is exported, represent that the sensing of red sub-pixel need not be accelerated；
If RR is less than R3, SR=3 is exported, expression need not sense red sub-pixel.Similarly, if RG is more than or equal to R2, export
SG=1, represent to need the sensing for accelerating green sub-pixels；If RG is less than R2, and is more than or equal to R3, then SG=2 is exported, represented
The sensing of green sub-pixels need not be accelerated；If RG is less than R3, SG=3 is exported, expression need not sense green sub-pixels.If
RB is more than or equal to R2, then exports SB=1, represents to need the sensing for accelerating blue subpixels；If RB is less than R2, and is more than or equal to
R3, then SB=2 is exported, represent that the sensing of blue subpixels need not be accelerated；If RB is less than R3, SB=3 is exported, expression need not
Sense blue subpixels.Tri- outputs of SR, SG and SB are combined into the second comparative result set.If the second comparative result collection is combined into
【3,1,2】, illustrate green sub-pixels aging, then its corresponding sensing modes senses the sensing modes of green sub-pixels for quickening.
In yet another embodiment of the present invention, if the signal of input is RGBW signals, need RGBW tetra- respectively
The display ratio of kind color obtains the 3rd comparative result set compared with first threshold, so as to according to the 3rd comparative result
Sensing modes corresponding to set determination.That is, tetra- outputs of SR, SG, SB and SW are combined into the 3rd comparative result set.Root
According to aforementioned four comparative result, to determine the sub-pixels ageing of which kind of color, accelerate the sensing of the sub-pixel.
, can be respectively by tetra- kinds of RGBW in yet another embodiment of the present invention in order to further improve the accuracy of sensing
The display ratio of color obtains the 4th comparative result set, then according to the 4th compared with Second Threshold and the 3rd threshold value
Sensing modes corresponding to comparative result set determination.Such as：4th comparative result collection is combined into【1,2,3,1】, illustrate red and white
Color it is sub-pixels ageing, it is necessary to accelerate to sense；Green sub-pixels sense without accelerating；Blue subpixels are without sensing.
S64, under sensing modes, display data is compensated using sensing mode corresponding with sensing modes, so that
Display data after display device display compensation.
It is determined that after sensing modes, sensing mode corresponding with sensing modes can be used to compensate display data,
So that the display data after display device display compensation.Such as：Sensing modes for accelerating sensing red sub-pixel, can be according to
Mode that red, red, green, blueness are circulated senses so that display device can quickly compensate red sub-pixel
Aging, eliminate the image retention of red.
Again for example：It is combined into the 4th comparative result collection【1,2,3,1】Go on to say, as shown in fig. 7, can be according to red, red
The mode that color, green, white, white ... are circulated senses so that display device can quickly compensate red sub-pixel and
The aging of white sub-pixels, eliminate red and white image retention.
The display control method of the display device of the embodiment of the present invention, by calculating the aobvious of each color in preset time period
Show ratio to determine the sensing modes of display device, then display data is mended using sensing mode corresponding with sensing modes
Repay, so that the display data after display device display compensation, can quickly and efficiently be eliminated because certain color long-time large area shows
Show and caused by image retention, lift the picture quality of display.
