Specifically, please further referring to Fig. 3, comprising: first step 111 and second step 112；First edge pixel group
2 are located at the first step 111；Second step 112 is adjacent with first step 111, and the step edge of second step 112 is located at the
Side of one step 111 close to viewing area；It is namely less in the sub-pixel quantity of step edge second step.Step interval 12
Including first step interval 121 and second step interval 122；First step interval 121 is located at the first step 111 and described
Between second step 112；Second step interval 122 is adjacent with first step interval 121, and is set to first step interval 121
Side far from first step 111；Second drive array 32 is set to second step interval 122.
Further, second step 112 include second edge pixel group 5 and with the second edge pixel group sub-pixel
The third drive array 33 to connect one to one；Third drive array 33 is set to the apex angle of second step 112；Second driving battle array
The drive array of same color sub-pixel is driven to share same data line in column 32 and the third drive array 33.It is exemplary
, drive the third drive array 33 of the third sub-pixel 23 in second edge pixel group 5 to transmit data-signal by data line D2；
The second drive array 32 of the third sub-pixel 23 in first edge pixel group 2 is driven to transmit data-signal by data line D1；Number
According to line D1 by connecting line L1 connection data line D2, and share same data line.Data line D2 extends along column direction for position
Data-signal is transmitted in the sub-pixel of same row.Due to different colours sub-pixel the data value signal under same grayscale not
It is identical, cause the range of the sub-pixel data signal value of different colours not identical.And there is parasitism in data line in drive array
Capacitor causes data-signal also to need to charge to parasitic capacitance while storage capacitance is written.And two frames before and after data-signal
The case where difference is bigger, and the charging time is longer, is more easy to appear undercharge.Due to the data-signal model of different colours sub-pixel
It encloses and differs bigger, therefore, same data line can be easy to make when charging to the corresponding drive array of the sub-pixel of different colours
At undercharge.In the present embodiment, the of same color sub-pixel will be driven in the second drive array and third drive array 33
Three drive arrays 33 share same data line, so that the range of data-signal will not change, avoid charging the second driving battle array
Undercharge caused by 32 charging time of column is too long.On the other hand, relative to the sub-pixel with the second drive array with a line,
The sub-pixel and drive array of two steps 112 are more, and data line corresponding with third drive array 33 drives battle array second
Corresponding row is arranged without driving corresponding sub-pixel, therefore can be used for driving the second drive array 32.And it is located at the second driving
The number of step corresponding drive array of the array 32 far from 111 side of first step is of the row less than third drive array
The corresponding sub-pixel number of step causes it to have the drive being correspondingly connected with its data line in the row where the second drive array 32
Dynamic array and sub-pixel.If it will cause the two, and short circuit occurs for shared data line therewith for the second drive array 32, can not be normal
Driving.Therefore, second drive array 32 of the present embodiment and columns are more, the drive array of step further from display zone position is total
With data line, avoid that short circuit phenomenon occurs.
In addition, the second drive array 32 is set to second step interval 122 rather than first step interval by the present embodiment
121.Theoretically, third sub-pixel 23 of the first step interval 121 in first edge pixel group 2 is closer, but if will
Second drive array is set to first step interval 121, then the second drive array 32 needs the drive array with second step 112
Positioned at same a line, that is, it needs to receive scanning signal simultaneously with the drive array of second step 112, and data-signal is written.
At this point, can if the sub-pixel of the second drive array 32 and driving same color in third drive array 33 shares same data line
It causes the two to share scan line and data line, is equivalent to the two and short circuit occurs.And the second drive array is set to by the application
Two step intervals 122 avoid sharing scan line so that it is located at different rows from third drive array, so as to share number
According to line.
It is another partial enlargement diagram of Fig. 1 in B area please continue to refer to Fig. 4 and Fig. 5, Fig. 5；Third sub-pixel 23

In compared to first step 111, third step interval 123 is located at the side closer to driving chip IC.Therefore defeated in sequence
Out when scanning signal, its signal can be coupled to the first connecting line 40 when scanning signal jumps, to influence first edge picture
The light that the third sub-pixel 23 of element group 2 emits.The application by the first connecting line 40 be set to 951 same layer of first electrode, can
To increase the spacing between the first connecting line 40 and the second connecting line 42, reduce coupled capacitor between the two, to subtract as far as possible
The small scanning signal jump influence luminous for the third sub-pixel 23 in first edge pixel group 2.
Further, there are the first overlapping region S1 for the first connecting line 40 and the second connecting line 42, in the first overlapping region
S1, the first connecting line 40 and the second connecting line 42 are overlapping；

Sub-pixels.According to the curve of driving transistor work, its slope of the relatively high region of electric current is big.Namely identical voltage difference
The case where can generate bigger current difference.Since the application is by the 5th sub-pixel and corresponding second drive array of the 6th sub-pixel
32 openings far from the 5th sub-pixel and the 6th sub-pixel, therefore it necessarily will cause voltage difference.Therefore, the application is sub by the 5th
Pixel is set as red sub-pixel, the 6th sub-pixel is set as green sub-pixels and can produce lesser current difference, so that
The variable quantity of light emission luminance reduces as far as possible.It should be noted that third sub-pixel can be in the embodiment of Fig. 3 and Fig. 5

Electric current and power supply signal PVDD are directly proportional to the difference of data-signal data in machine light emitting display panel, when data-signal is smaller
When, brightness is higher.For these reasons, in the present embodiment, since there are resistance to cause current reduction on the first connecting line 40,
Corresponding sub-pixel luminence decline.In the present embodiment, more by the capacitance setting of the second storage capacitance of the second drive array 32
Greatly, cause data-signal charging in 32 data line charging process of the second drive array that can seem compared to the first drive array 31
Undercharge.Undercharge causes data-signal relatively low, and the driving current that the second drive array 32 generates at this time is bigger than normal, just
It cancels out each other with current reduction caused by the resistance on the first connecting line 40, so that the sub-pixel of the second drive array 32 driving is bright
