The quantity of the pixel cell 13 of the electrical connection of signal wire 2；The Part II of power signal line 2 corresponding with first area 101 is walked
Line 202 is snakelike cabling.
Specifically, as shown in figure 12, because the edge of viewing area 1 is round rectangle, consistent in the size of pixel cell 13
Under the premise of the quantity of a row pixel cell 13 in first area 101 be less than the number of a row pixel cell 13 in second area 102
Amount, and then make it that load is less than the electricity being located in second area 102 corresponding to the power signal line 2 in first area 101
Loaded corresponding to source signal line 2, in order that being loaded and positioned at second corresponding to the power signal line 2 in first area 101
Load is generally equalized corresponding to power signal line 2 in region 102, and does not influence the structure design of viewing area 1, can be by position
The Part II cabling 202 of power signal line 2 in first area 101 is designed as snakelike cabling, i.e. increase is located at the firstth area
The length of the Part II cabling 202 of power signal line 2 in domain 101, so as to increase the letter of the power supply in first area 101
Number line 2 loads, so that load and the electricity in second area 102 corresponding to the power signal line 2 in first area 101
Load is generally equalized corresponding to source signal line 2, after using above-mentioned design, can imitate the display of each opening position of display panel
Fruit is relatively uniform, so as to improve the display effect of display panel.
It should be noted that can also be in the Part II cabling 202 of the power signal line 2 in first area 101
Middle increase ohmic load or capacitive load, for example, in the Part II cabling of the power signal line 2 in first area 101
Increase polysilicon cabling in 202, the polysilicon cabling serpentine configuration, specific implementation side can also be designed to according to being actually needed
Formula is not especially limited herein according to setting is actually needed, certainly can also power signal line 2 corresponding with first area 101
Part II cabling 202 be arranged to other shapes, for example, polyline shaped or curve-like etc., to pass through increase and first area 101
The length of the Part II cabling 202 of corresponding power signal line 2 increases the power signal line 2 in first area 101
Corresponding load, the walks wire shaped on the power signal line 2 in first area 101 are not especially limited herein.
Alternatively, as shown in Figure 8 and Figure 9, the second of at least one power signal line 2 corresponding with first area 101
Part cabling 202A line width is less than the line width with Part I cabling 201.
Specifically, due to being additionally provided with other cablings in the film layer where anode block 8, it is located at first area to reduce
Occur the situation of short circuit when the Part II cabling 202A of power signal line 2 in 101 is set with anode block 8 with layer, as Fig. 8 with
Shown in Fig. 9, the Part II cabling 202A set with anode block 8 with layer line width can be set smaller than the Part II and walked

By Part III cabling 203 and it is in parallel with the Part II cabling 202A that anode block 8 is set with layer after, equivalent to increase with
The line width for the Part II cabling 202A that anode block 8 is set with layer, reduce Part II cabling 202A and be arranged on the institute of anode block 8
In the load of the power signal line 2 of layer, so as to reduce the gap of the load of the power signal line 2 in different zones, so as to
Lift the display effect of display panel.
Alternatively, as shown in figure 13, Part III cabling 203 with this at least one with 101 corresponding power supply of first area
The different layers of Part II cabling 202A of signal wire 2 are set.
Specifically, due to by the Part II cabling 202A and anode of the power signal line 2 in first area 101
When block 8 is set with layer, the space that can be connected up in the film layer where anode block 8 is relatively small, in order that Part III cabling 203
With certain line width, it can set Part III cabling 203 and the different layers of corresponding Part II cabling 202A, for example, as schemed
Shown in 13, Part III cabling 203 and Source and drain metal level 65 can be made to be set with layer, can also with thin film transistor (TFT) 6 other
Film layer is set with layer, is not especially limited herein.
Alternatively, as Figure 13, Part III cabling 203 are set with Part I cabling 201 with layer.
Specifically, as shown in figure 13, Part III cabling 203 is set with Source and drain metal level 65 with layer, and Part III is walked
Line 203 and Part II cabling 202A electrical connections in parallel, and all electrically connected with corresponding Part I cabling 201.
Alternatively, as shown in figure 12, the pixel cell 13 that power signal line 2 corresponding with second area 102 electrically connects
Quantity is more than the quantity of the pixel cell 13 of the electrical connection of power signal line 2 corresponding with first area 101；Part III cabling
203 and the Part II cabling 202 of at least one power signal line 2 corresponding with first area 101 be all snakelike cabling；Such as
Shown in Figure 13, the orthographic projection of Part III cabling 203 on a display panel and at least one electricity corresponding with first area 101
The orthographic projections of the Part II cabling 202A of source signal line 2 on a display panel are completely overlapped.
Alternatively, the Part II cabling 202A set on Part III cabling 203 and with anode block 8 with layer shape
Content corresponding to Figure 12 is referred to, is specifically no longer described in detail.When the orthographic projection of Part III cabling 203 on a display panel and
When the orthographic projection on Part II cabling 202A display panels set with anode block 8 with layer is completely overlapped, the 3rd can be made
The span for dividing cabling 203 and Part II cabling 202A to take up space is relatively small, so that can be more in display panel
Space is used to show, therefore is advantageous to improve the display area of display panel.
