Referring to Fig. 8, Fig. 8 is the structural schematic diagram of another embodiment of the application display panel, Fig. 9 is abnormity in Fig. 8
The enlarged diagram of one embodiment of viewing area.The display panel further include: arc edge 70, each column repetitive unit 5a include four
A adjacent main pixel, the specific structure of repetitive unit 5a can be found in the related description in above-mentioned corresponding embodiment, herein not
It repeats again.First main pixel 72 in two main pixels adjacent to arc edge 70 of each column repetitive unit 5a deducts second
Sub-pixel 2e and third sub-pixel 2f, second main pixel 74 deduct the first sub-pixel 2d.In the present embodiment, above-mentioned arc-shaped edges
Edge 70 is the outer edge of display panel, and the viewing area adjacent with arc edge 70 can be referred to as special-shaped viewing area, and the abnormity is aobvious
Show that area includes special-shaped edge of display area 76, the main pixel 72 or 74 for constituting special-shaped edge of display area 76 is to lack the first sub-pixel
2d, the second sub-pixel 2e, any one in third sub-pixel 2f or two incomplete pixels, all incompleteness pixels are at its unfilled corner
It is adjacent to constitute special-shaped edge of display area 76 two-by-two.Since the second sub-pixel 2e, third sub-pixel 2f group become convex
Shape (matches) with the first sub-pixel 2d of recessed quadrangle, thus in special-shaped edge of display area 76 partial region by the second sub-pixel
2e, third sub-pixel 2f concave portion occupy, this reduces the gap between special-shaped edge of display area 76 and arc edge 70,
Be conducive to improve the area of light emitting region in display panel.Certainly, in other embodiments, special-shaped viewing area is also possible to groove
Area etc., the groove area include oblique edge, and the oblique edge and line direction X have first angle, and first angle is greater than 0 degree and is less than
90 degree, mode provided herein can also be used in the pixel arrangement mode of the viewing area adjacent with the oblique edge.
It is reflex angle that the first sub-pixel 2d, which is located at the angle inside main pixel, in embodiment given by above-mentioned Fig. 9.When first
Sub-pixel 4a is located at the angle inside main pixel when being obtuse angle, and the pixel arrangement mode close to arc edge 70a is as shown in Figure 10.
In the present embodiment, each column repetitive unit 5c include four adjacent main pixels, in repetitive unit 5c, the first sub-pixel 4a with
The mode of right angle splicing is adjacent two-by-two.First in two main pixels adjacent to arc edge 70a of each column repetitive unit 5c
A main pixel 72a deducts the second sub-pixel 4b and third sub-pixel 4c, second main pixel 74a deduct the first sub-pixel 4a.With
Fig. 9 is similar, and Figure 10 can equally reduce the gap between special-shaped edge of display area and arc edge, is conducive to improve display panel
The area of middle light emitting region.
When the angle inside the first sub-pixel 3a is located at main pixel is the straight angle, i.e. when the first sub-pixel 3a is triangle,
Pixel arrangement mode close to arc edge 70b is as shown in figure 11, and in the present embodiment, each column repetitive unit 5d includes four phases
Adjacent main pixel, in repetitive unit 5d, the first sub-pixel 3a is adjacent two-by-two in such a way that right angle splices.Each column repetitive unit 5d
Two main pixels adjacent to arc edge 70b in first main pixel 72b deduct the second sub-pixel 3b and third sub- picture
Plain 3c, second main pixel 74b deduct the first sub-pixel 3a.Similar with Fig. 9 and Figure 10, Figure 11 can equally reduce special-shaped display
Gap between area edge and arc edge is conducive to the area for improving light emitting region in display panel.
In an application scenarios, realize that the mode of above-mentioned special-shaped viewing area can be, in line direction X or column direction Y
On, single sub-pixel includes more than the first part at the non-display area edge close to special-shaped viewing area, if the area of first part
Area ratio with single sub-pixel is less than 1/2, then the sub-pixel retains, and otherwise scratches the sub-pixel and removes, ultimately forms display
The practical light emitting region of panel.
