Area c, the opening area of the 4th sub-pixel 204 is d, and the opening area of the 5th sub-pixel 205 is e, and the 6th sub-pixel 206 is opened
Open area is f, wherein, a:b:C=d:e:f.
Since special-shaped pixel unit is limited by heterotype edge, opening area is less than the first pixel unit (normal pixels
Unit) opening area.The special-shaped pixel unit of heterotype edge is arranged on during being lit, since its opening area is smaller,
Cause the current density that it is subject to relatively large, the brightness of unit area is higher, be easy to cause edge bright spot.And due to close
The special-shaped pixel unit of heterotype edge is during white light is shown, by the opening area and normal pixels of its sub-pixel included
The opening area of sub-pixel that unit (the first pixel unit) is included differs, and asking for colour cast easily occurs at heterotype edge
Topic.
In the present embodiment, due to the first sub-pixel 201, the second sub-pixel 202 and included by special-shaped pixel unit 220
The ratio between opening area of three sub-pixels 203, with the 4th sub-pixel 204, the 5th sub-pixel included by the first pixel unit 210
205 and the 6th sub-pixel 206 the ratio between opening area it is equal, therefore, special-shaped pixel unit 220 is wrapped during display
The brightness ratio one of sub-pixel that the brightness ratio of the sub-pixel contained is included with the first pixel unit 210 (conventional pixel cell)
It causes, so as to avoid that bright spot is generated at heterotype edge.Meanwhile the display effect of special-shaped pixel unit and the first pixel unit (conventional picture
Plain unit) display effect it is identical, i.e., special-shaped pixel unit will not generate colour cast during white light is shown, so as to avoid different
The generation of colour cast at shape side.
There are many arrangement modes of special-shaped pixel unit in the present embodiment, and following two are illustratively enumerated in the present embodiment
Kind arrangement mode,
In a kind of specific embodiment, as shown in fig. 6, its organic light emitting display for being provided by the embodiment of the present invention
Another structure diagram of panel, in the plane of special-shaped display area 22, the first sub-pixel 201,202 and of the second sub-pixel
Third sub-pixel 203 is arranged on same a line, and positioned at the first sub-pixel 201, the second sub-pixel 202 and third sub- picture with a line
The shape on the side of plain at least one of 203 sub-pixels is identical with the shape of heterotype edge 25.
Due to being limited along the special-shaped pixel unit of heterotype edge by heterotype edge, included by the first sub-pixel,
The opening area of at least one of two sub-pixels and third sub-pixel is small, in order to ensure the first sub-pixel, the second sub-pixel and
The ratio between opening area of third sub-pixel, with the ratio between the opening area of the 4th sub-pixel, the 5th sub-pixel and the 6th sub-pixel phase
Together, the first sub-pixel, the opening area of the second sub-pixel and third sub-pixel included by special-shaped pixel unit can be adjusted
It is whole.Illustratively, with reference to the arrangement mode of above-mentioned first sub-pixel, the second sub-pixel and third sub-pixel, in special-shaped pixel list
In member 22, sub-pixel (the second sub-pixel 202 and third sub- picture smaller or do not influenced by heterotype edge can will be influenced by heterotype edge 25
Element opening area 203) is adjusted, and makes opening for the ratio between opening area of three and three sub-pixels in the first pixel unit
The ratio between open area is identical.Specifically, as shown in fig. 6, in the plane of special-shaped display area 22, deviate from heterotype edge along line direction
On 25 direction, special-shaped pixel unit 220 includes the first sub-pixel 201, the second sub-pixel 202 and third sub-pixel 203 successively,
Wherein the second sub-pixel 202 is being less than the 5th sub-pixel 205 along the width m on line direction along the width x on line direction,
Third sub-pixel 203 is being less than the 6th sub-pixel 206 along the width n on line direction along the width y on line direction.
For example, the color of the 4th sub-pixel 204 is red in the first pixel unit 210, the color of the 5th sub-pixel 205 is
Green, the color of the 6th sub-pixel 206 is blue, and the ratio of the opening area of three is d:e:F=7:7:8；At this point, adjustment is different
The opening area of the second sub-pixel 202 and third sub-pixel 203 in shape pixel unit 220 so that the first sub-pixel 201,
The opening of three sub-pixels in the ratio and the first pixel unit 210 of the opening area of two sub-pixels 202 and third sub-pixel 203
Area is identical, i.e. a:b:C=7:7:8.Due to the opening face of the sub-pixel in special-shaped 22 and first display area 21 of display area
The ratio between product is identical, then during display, the brightness sent out in this display area is more balanced, avoids special-shaped display area
Bright spot in (edge of display area).Meanwhile the display effect of special-shaped pixel unit and the first pixel unit (normal pixels list
Member) display effect it is identical, i.e., special-shaped pixel unit will not generate colour cast during white light is shown, so as to avoid heterotype edge
The generation of the colour cast at place.
It should be noted that, although the second sub-pixel 202 and third sub-pixel 203 are adjusted in the width of line direction
It is whole, but its normal display can't be influenced.This is because the first sub-pixel in the present embodiment in special-shaped pixel unit 220
201st, the shape of the second sub-pixel 202 and third sub-pixel 203 is rectangle, wherein, the long side direction of three is column direction,
Therefore, the adjustment of the width to the second sub-pixel 202 and third sub-pixel 203 in the row direction, although increasing the second sub- picture
Spacing between element 202 and third sub-pixel 203, when luminous, light is for the second sub-pixel 202 and third sub-pixel 203
It spreads apart what is come around from opening, stain will not be caused, therefore display can't be impacted.
You need to add is that the multiple special-shaped pixel units 220 set along heterotype edge 25, due to by heterotype edge 25
Difference is influenced, opening area is also different, that is to say, that when being adjusted, second in each abnormity pixel unit
The adjusted value of sub-pixel and third sub-pixel is not a definite value, needs to carry out different adjustment according to different products, should
Adjusted value is subject to specific product.
