To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing to the present invention make into
It is described in detail to one step, it is clear that described embodiments are only a part of the embodiments of the present invention, rather than whole implementation
Example.Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
All other embodiment, shall fall within the protection scope of the present invention.
Due to the presence of RC loading in display panel, so that driving circuit is the scanning letter provided at the top of pixel array
Number pot life and the scanning signal provided for pixel array bottom pot life between can have larger difference.Fig. 1 is
A kind of display panel structure schematic diagram, as shown in Figure 1, display panel includes pixel array 1, control circuit 2 and driving circuit 3.
Driving circuit 3 includes multiple driving units 31, and each driving unit 31 passes through scanning signal with the one-row pixels in pixel array 1
Line connection.In display panel work, the driving unit 31 corresponding with row pixel to be scanned into driving circuit 3 of control circuit 2
Clock signal is provided, which generates scanning signal according to clock signal and be supplied to row pixel to be scanned, thus real
The scanning to row pixel is showed.
However, display panel structure as shown in Figure 1 is as it can be seen that multiple driving units 31 in driving circuit 3 are electric away from control
The distance on road 2 is not identical.Driving unit 31 at the top of display panel is relatively located at display panel away from the distance of control circuit 2
The driving unit 31 of bottom is much bigger away from the distance of control circuit 2, and therefore, reaching will exist at the top of display panel clock signal
More serious RC loading problem, and the scanning signal according to caused by clock signal also will receive shadow at the top of display panel
It rings.Fig. 2 is a kind of display panel different zones scanning signal schematic diagram, as shown in Fig. 2, the bottom of display panel, middle part, top
Due to RC loading problem, there is different degrees of deformation in the waveform of scanning signal, leads to different zones scanning signal
Pot life occurs different.So-called pot life refers to that scanning signal generates the time of control action to pixel.For scanning
For signal, it is used to change by low and high level the unlatching and closure of transistor in control pixel circuit, shown in Fig. 2
Scanning signal is the transistor opened in pixel circuit by low level, closes the crystal in pixel circuit by high level
Pipe.Since low level duration is different in scanning signal, so that transistor in the pixel circuit of display panel different zones
Opening time occur it is different, for example, transistor opening time in Fig. 2 in the pixel circuit of bottom just than middle part pixel circuit and
The opening time of transistor in top pixel circuit is long.Since the opening time of transistor in pixel circuit determines that data are believed
Number write time, therefore, existing display panel can cause middle part pixel and top pixel number due to RC loading problem
It is insufficient according to being written, reduce the homogeneity of display panel.
To solve the above-mentioned problems, display panel homogeneity is improved, the embodiment of the present invention provides a kind of pixel array control
Method, this method are applied to control device.When the control device is installed in display panel, display panel can be equivalent to
Control circuit.Fig. 3 is a kind of pixel array control method provided in an embodiment of the present invention, as shown in Figure 3, comprising the following steps:
S301: control device determines subregion to be scanned.
S302: control device controls driving circuit and sends the corresponding scanning letter of subregion to be scanned to subregion to be scanned
Number；The pot life of scanning signal extends with the increase of distance between subregion and control device.
In the pixel array control method provided by the embodiment of the present invention, control device has carried out region to pixel array
Change management, pixel array includes multiple subregions, and any subregion includes that at least one-row pixels, driving circuit is scanned by N item
Signal wire is connect with every one-row pixels in the pixel array respectively, and N is not less than 1.In order to make it easy to understand, Fig. 4 is that the present invention is real
Apply a kind of pixel array subregion schematic diagram of example offer, it should be appreciated that can not between all subregion in actual pixel array
There are apparent area limits, for example, there is no obvious in actual pixels array for the third line pixel and fourth line pixel in Fig. 4
Boundary, the division of subregion is realized in control device.
In S301, control device may determine that the line number scanned, row pixel to be scanned be determined, so that it is determined that wait sweep
The affiliated subregion of row pixel retouched is subregion to be scanned.For example, pixel array in such as Fig. 4, row 1 to row 3 belong to sub-district
Domain 1A, row 4 to row 6 belong to subregion 1B, then when control device 2 (when control device is applied in display panel, is equivalent to control
Circuit 2) confirmation scan line 2 when, confirmation row 2 belongs to subregion 1A, and subregion to be scanned is 1A, scans when control device 2 confirms
When row 4, confirmation row 4 belongs to subregion 1B, and subregion to be scanned is 1B.
In S302, control device controls driving circuit and sends the corresponding scanning of subregion to be scanned to subregion to be scanned
Signal；The pot life of scanning signal extends with the increase of distance between subregion and control device.For example, sub-district in Fig. 4
The distance of domain 1A distance control apparatus 2 is bigger than the distance of subregion 1B distance control apparatus 2, then the scanning signal of subregion 1A is available
Time can be longer than the pot life of the scanning signal of subregion 1B.It should be understood that scanning letter between subregion 1A and subregion 1B
For the difference of number pot life is only for control device 2, what the pixel in subregion 1A and subregion 1B was an actually-received
The pot life of scanning signal 2 can be reached unanimity due to RC loading.
In a kind of feasible implementation of S302, control device determines the corresponding clock signal of subregion to be scanned,
And it is supplied to driving circuit；Driving circuit is corresponding according to the corresponding clock signal generation of subregion to be scanned subregion to be scanned
Scanning signal, and scanning signal is sent to subregion to be scanned.
For example, being previously stored in control device in pixel array between multiple subregions and different clocks signal
Corresponding relationship, subregion 1A correspond to clock signal a, and subregion 1B corresponds to clock signal b.Control device is determining row picture to be scanned
When element is row 3, determines that subregion to be scanned is subregion 1A belonging to row 3, clock signal a is just supplied to row 3 in driving circuit
Corresponding driving unit, the pixel for making the driving unit generate scanning signal a according to clock signal a and being supplied in row 3.Due to
Clock signal corresponding to same subregion is identical, and therefore, driving circuit is the scanning letter that the pixel in same subregion provides
It is number also identical.
In existing display panel, driving circuit can generate scanning signal according to clock signal.The reality of above-mentioned S302
Existing mode allows control device by adjusting clock signal to change driving electricity on the basis of existing display panel structure
The pot life of scanning signal caused by road is realized compatible with existing display panel.
To sum up, due to the influence of RC loading, cause the pot life of the scanning signal provided at the top of pixel array with
There can be larger difference between the pot life of the scanning signal of pixel array bottom, influence the homogeneity of display panel.In Fig. 3
Shown in pixel array control method, the pixel array of display panel is divided into multiple subregions, by for each sub-district
The mode of different pot lifes is distributed to make up RCloading difference caused by scanning signal, to improve display panel in domain
Homogeneity, improve the display effect of display panel.
In the pixel array control method provided by the embodiment of the present invention, the different subregions of pixel array are corresponding with not
Same clock signal.In a kind of feasible implementation, the period of clock signal is fixed, and the duty ratio of clock signal is with sub-district
The increase of distance between domain and control device and extend；The duty ratio of clock signal be clock signal in the first level time and when
The ratio of clock signal period；First level time and the pot life of scanning signal are positively correlated.Fig. 5 provides for the embodiment of the present invention
A kind of feasible clock signal schematic diagram, be applied to display panel shown in Fig. 4, in Fig. 5, CLKa is corresponding with subregion 1A
Clock signal, CLKb be clock signal corresponding with subregion 1B, CLKc be clock signal corresponding with subregion 1C.Its
In, the low level of clock signal is the first level, as seen from Figure 5, CLKa, CLKb and CLKc cycle T having the same, but CLKa
The first level it is practical be t1, the first level time of CLKb is t2, and the first level time of CLKc is t3, wherein t1, t2,
T3 is sequentially reduced, i.e. the first level time t and the ratio of cycle T are sequentially reduced.Due to the first level time in clock signal
It is positively correlated with the pot life of scanning signal, therefore, according to the pot life of CLKa, CLKb and CLKc scanning signal generated
It can be sequentially reduced, make " pot life of scanning signal reduces with the reduction of distance between subregion and control device ", namely
" pot life of scanning signal extends with the increase of distance between subregion and control device ".
In the pixel array control method provided by the embodiment of the present invention, the different subregions of pixel array are corresponding with not
Same clock signal.In another feasible implementation, the duty ratio of clock signal is fixed, and the period of clock signal is with son
The increase of distance between region and control device and extend；The duty ratio of clock signal be clock signal in the first level time with
The ratio of clock signal period；Pot life in first level time and scanning signal is positively correlated.Fig. 6 is the embodiment of the present invention
The feasible clock signal schematic diagram of another kind of offer, is applied to display panel shown in Fig. 4, and in Fig. 6, CLKa is and subregion
The corresponding clock signal of 1A, CLKb are clock signal corresponding with subregion 1B, and CLKc is clock corresponding with subregion 1C letter
Number.Wherein, the low level of clock signal is the first level.As seen from Figure 6, the period of CLKa is T1, and the period of CLKb is T2,
The period of CLKc is T3, CLKa, CLKb and CLKc duty ratio having the same, therefore the ratio of the first level time t and cycle T
It is identical, and since T1, T2 and T3 are sequentially reduced, the first level of the first level time t1 of subregion 1A, subregion 1B
The first level time t3 of time t2 and subregion 1C can be also sequentially reduced, and be believed according to the scanning that CLKa, CLKb and CLKc are generated
Number pot life can also be sequentially reduced, make that " pot life of scanning signal subtracts with distance between subregion and control device
It is small and reduce ", namely " pot life of scanning signal extends with the increase of distance between subregion and control device ".
In above-mentioned feasible implementation, due to the change of clock signal period, different sons in display panel can be made
There is difference in the scan frequency of the scanning signal in region, and the frequency of scanning signal can be with distance between subregion and control device
Increase and reduces.Since data-signal needs to complete data write-in with scanning signal cooperation, control device also needs response to adjust
The frequency of entire data signal.Display panel as shown in Figure 4, control device 2 is also by M data signal wire and pixel array
Each column pixel connection；M is not less than 1.Optionally, control device 2 can also determine subregion to be scanned according to the scanning signal period
Data-signal data signal cycles, and provide data letter according to pixel of the data signal cycles into subregion to be scanned
Number, to guarantee that data-signal is synchronous with scanning signal.Generally, clock signal period is bigger, and the period of data-signal is bigger, example
