The present invention provides a kind of driving method, which is applied to display panel 100, the display panel 100 packet
Include multiple display subregions 111.
This method can be applied to common display panel, be more suitably applied to the display surface of high refresh rate and high brightness
Plate.
Illustrate by taking display panel 100 shown in FIG. 1 as an example, which is one and is spliced by multiple sub-screens 110
Made of mosaic screen, each sub-screen 110 is further divided into multiple display subregions 111.
Display subregion 111 in the present embodiment can divide according to the actual situation, for example, each sub-screen 110 is drawn
It is divided into transversely arranged or longitudinal arrangement multiple display subregions 111, it is clear that the division mode not office of display subregion 111
Be limited to this, it is also possible to be divided into it is latticed etc., in addition, the display subregion 111 divided is also not limited to a sub-screen
110, for example, can be by the region division in different sub-screens 110 in a display subregion 111.
Obviously, display subregion 111 divides more complicated, then drives the control process of the display panel 100 also more multiple
It is miscellaneous, biggish load can be carried out to hardware strap, so when actual implementation, it can be in the extending direction along scan line or data line
Each sub-screen 110 is divided into multiple display subregions 111, facilitates simplified control process.
Referring to fig. 2, Fig. 2 is a kind of flow chart of driving method provided in an embodiment of the present invention, as shown in Fig. 2, the driving
Method the following steps are included:
Step 201, the display brightness for obtaining each display subregion.
The display brightness for obtaining each display subregion in the present embodiment first, then by the identical display sub-district of display brightness
The same management in domain, it is understood that be display subregion to be divided into different groups according to display brightness, then same group
Same management, refreshes in the same fashion, with simplified control process.
As shown in Figure 1, illustrating so that display brightness includes six grades as an example in the present embodiment, wherein display in Fig. 1
The arrangement mode in region 111 is exemplary only, and display brightness when actual implementation should be determined according to the picture of required display,
Different filling line densities represents different display brightness in Fig. 1, and filling line density is bigger, then represents the display subregion 111
Display brightness it is lower.
The division of display brightness can be carried out according to same standard, can also be carried out according to various criterion.Here, it presses
It is referred to determining display brightness according to unified standard in whole display panels according to same standard.According to different standards into
It is capable then refer to setting different standards in different zones.
For example, central area is the region that user's sight is mainly concentrated, and user is for side for display panel
The sight intensity in edge region is then relatively small, therefore, display sub-zone dividing can be divided for central area more
Accurately, such as six grades are divided into, and for the Relative Fuzzy that fringe region then divides, such as four grades are only divided, have
Help power consumption and load that display panel is reduced in the case where guaranteeing display effect.
Clearly for relatively unessential region, such as above-mentioned fringe region, simplified control can also be carried out, that is, is determined
When the grade of display brightness, it is determined still according to the identical mode of middle section, but during driving, use is identical
Mode drive the display subregions of different display brightness, for example, the display subregion that the display brightness of fringe region is most bright
It is driven with the most bright display subregion of display brightness time according to identical driving method, is equivalent to and simplifies driving process.
In the present embodiment, middle section and fringe region can be divided according to a certain percentage, specifically, can be according to one
Fixed Aspect Ratio, such as the various numerical value such as 20%, 15% or 10% divide fringe region and middle section.
Step 202, the electricity required supplementation with that the display subregion is determined according to the display brightness of the display subregion
Lotus amount.
Display subregion higher for display brightness, the quantity of electric charge of required supplement is less, and brightness lower region then needs
Repeatedly refresh increase energy storage, that is to say, that the quantity of electric charge supplemented needed for each display subregion is with the brightness for showing subregion
Increase and reduce.
Step 203, each display subregion of control refresh, and supplement electricity according to the identified quantity of electric charge required supplementation with
Lotus.
The quantity of electric charge of each display subregion is supplemented in refresh process, and during supplementing charge, identical display is bright
The refreshing mode of the display subregion of degree be it is identical, different display brightness display subregion due to required supplement the quantity of electric charge
Difference, so its refreshing mode may be identical, it is also possible to not identical.
The quantity of electric charge that the embodiment of the present invention is supplemented needed for being determined according to the brightness of each display subregion, display brightness are higher
The quantity of electric charge in region, required supplement is fewer, in such manner, it is possible to rationally control refresh process, avoids excessively refreshing to supplement the quantity of electric charge,
The power consumption for facilitating reduction display panel, additionally aiding reduces hardware handles load.
Please continue to refer to Fig. 3, Fig. 3 is the flow chart of another driving method provided in an embodiment of the present invention, and shown in Fig. 2
Embodiment is compared, and the present embodiment, which further passes through image, to be converted to obtain the display brightness of each display subregion.
As shown in figure 3, in the embodiment, driving method the following steps are included:
Step 301, the RGB rgb signal that will acquire are converted to optimization color video YCrCb signal.
In general, the format for the display signal that display panel is supported is rgb format, the general degree of rgb signal and is answered
It is also higher with range, rgb signal be red (R), green (G) and indigo plant (B) three kinds of Color Channels superposition, so can not directly embody
Luminance information.And YCrCb signal (or YUV signal) be then embodied by luminance information (Y) and colors of image saturation degree, wherein
Cr reflects the difference between RGB input signal RED sector and rgb signal brightness value, and Cb reflection is RGB input signal
Difference between blue portion and rgb signal brightness value.So the luminance information Y that can be extracted in YCrCb signal is used as display
The display brightness of subregion.
A kind of feasible image conversion formula are as follows:
Y=0.299*R+0.587*G+0.114*B；
Cr=-0.169*R-0.331*G+0.5*B；
Cb=0.5*R-0.419*G-0.081*B.
According to above-mentioned formula, RBG signal can be converted to YCrCb signal, it is clear that the formula of signal format conversion is not
It is confined to the formula, the conversion process of the signal format can not also be made herein with reference to other modes in the related technology into one
Step limits and description.
Step 302, the display by extraction luminance information Y in the YCrCb signal as the corresponding display subregion
Brightness.
After completing format conversion, Y value obtained can be used as the display brightness of corresponding display subregion.
Step 303, the electricity required supplementation with that the display subregion is determined according to the display brightness of the display subregion
Lotus amount.
When implementation, the absolute value of the quantity of electric charge is supplemented needed for each display subregion can be determined according to display brightness, i.e., specifically
Numerical value.
Further, it is also possible to the relative value of the supplement quantity of electric charge needed for determining.By the highest display subregion institute of display brightness
The quantity of electric charge that need to be supplemented is minimum, it is possible on the basis of the corresponding quantity of electric charge of the display brightness, on this basis, successively determine
The corresponding quantity of electric charge of display subregion of secondary display brightness, and complete the supplement of charge.
It should be understood that show that there are many quantity of subregion when actual implementation, included by each display panel, and by
In the content of display itself be continuous, it is possible to think there are it is multiple display subregions display brightness be continuous and gradient
Variation, change of gradient refers to that brightness improves step by step here, for instance it can be possible that improving step by step according to gray-scale intensity.Therefore, may be used
On the basis of the quantity of electric charge of the supplement needed for the highest display subregion of display brightness, each gradient is determined in such a way that gradient is incremented by
The quantity of electric charge, as corresponding display brightness display subregion needed for supplement the quantity of electric charge.
Step 304, each display subregion of control refresh, and supplement electricity according to the identified quantity of electric charge required supplementation with
Lotus.
In this way, the present embodiment further improves the convenience journey of versatility and control by converting to picture format
Degree.
In an optional embodiment, which may include:
Each display subregion is controlled to refresh with identical frequency.
In this specific embodiment, the refreshing frequency of the display subregion of different display brightness is all the same, bright except showing
It spends in other display subregions outside minimum display subregion, when refreshing at least once, the quantity of electric charge supplemented is 0.
It should be understood that the quantity of electric charge supplemented needed for subregion is most for display brightness minimum showing, so needing to mend
The quantity of electric charge filled is also most, so, the minimum display subregion of display brightness may require supplementation with charge every time, it is also possible to simultaneously
It does not need to supplement charge every time.When implementation, in order to avoid unnecessary refreshing, refreshing frequency is reduced, can control display sub-district
The minimum region of the display brightness in domain requires supplement charge in each refresh.
For the display subregion slightly higher for display brightness, the display minimum less than display brightness of the quantity of electric charge of supplement
Subregion, so, when refreshing at least once, the quantity of electric charge supplemented is 0.
The quantity of electric charge of the supplement as needed for display brightness higher display subregion is fewer, so with display subregion
The increase of display brightness, the number that each quantity of electric charge for showing subregion supplement is 0 are consequently increased.
When the quantity of electric charge required supplementation with is 0, although these display subregions need to maintain higher refreshing frequency,
It can send out sky, that is, send empty data " 0 ", and it is relatively low to send out empty load, therefore can reduce the power consumption of display panel.
In another optional specific embodiment, which may include:
Each display subregion is controlled to refresh with different refreshing frequencys.
As shown in figure 4, sequence controller can be passed through when each display subregion 111 is refreshed with different refreshing frequencys
401 control its refresh process.
Referring to Fig. 4, when the refreshing of display subregion of different display brightness is controlled in Fig. 4 by sequence controller 401
The refreshing timing of sequence, the display subregion 111 of different display brightness is different, for example, the display subregion 111 of the leftmost side
Display brightness highest, the specific embodiment Chinese Control device refresh at first, are next display of display brightness time level-one
Region 111.It is omitted some Flushing status in figure and refreshes timing, details are not described herein again.
It should be understood that the quantity of electric charge supplemented is equal, and the display that display brightness is lower every time in refresh process
The quantity of electric charge supplemented needed for subregion 111 is more, so the number refreshed needed for the lower display subregion 111 of display brightness is just
It is more, correspondingly, its refreshing frequency is also higher.The refreshing frequency of i.e. each display subregion 111 is with the aobvious of the display subregion
Show that brightness increases and reduces.
In this way, since the quantity of electric charge supplemented when different display subregions 111 refresh every time is identical, so each regional luminance
Variable quantity is also consistent, i.e. the brightness change of display panel is more uniform, simultaneously as entire display panel, scanning time
Several average value is less, it is understood that reduces for the refreshing frequency mean value of display panel entirety, helps to save power consumption.
Sequence controller 401 specifically refers to the relevant technologies, is not further qualified and describes herein.
Optionally, in above two specific embodiment, when each display subregion refreshes, with binary numeral
The quantity of electric charge supplement charge.
The corresponding brightness step variation of binary system charge value, characterizes luminance accuracy, when supplement amount of charge is identical every time,
(the supplementary number can also characterize luminance accuracy, in this way, facilitating simplified control process, reduce the occupancy for hardware load.
As shown in figure 5, may be summarized to be in the specific embodiment, is converted by format and be converted to the format of image
Then YCrCb format extracts luminance information Y therein as display brightness and saves, next determine a Benchmark brightness
Value, such as can be the display brightness of most bright display subregion, then according to call format layout display brightness array, finally
Refreshing is controlled the display panel to supplement charge.
In refresh process, first next transmission Benchmark brightness information sends supplement brightness to meet brightness initial value requirement
Information supplements the display subregion of each display brightness, and the process of transmission supplement luminance information may continue repeatedly repeatedly, such as
Supplemented in second of transmission process be first gradient luminance information, the display subregion of corresponding level-one display brightness,
Supplemented in n-th transmission process be the N-1 gradient luminance information, and so on, until last time transmission process in
