Sub-pixels row spyG and blue subpixel column spyB are set gradually, and in a pixel p, green sub-pixels spG is misplaced
Arrangement so that in the same pixel p, the distance between red sub-pixel spR and green sub-pixels spG will increase, adjacent pixel p
In, between red sub-pixel spR close to each other and green sub-pixels spG between be separated with blue subpixels spB, it is therefore, organic
It is not easy red green colour mixture occur in light emitting display panel on the whole, reduces red green colour mixture probability, promotes user experience.
Fig. 8 is the pixel arrangement schematic diagram of another organic light emitting display panel provided in an embodiment of the present invention, in one kind
In embodiment, as shown in figure 8, it is W1 that the width of red sub-pixel spR and green sub-pixels spG in a first direction on x is equal,
The width of blue subpixels spB is W2, for example, red sub-pixel spR and green sub-pixels spG are round rectangle, blue
Pixel spB is circle, or is alternatively other rules or irregular shape.
In the organic light emitting display panel that the embodiment provides, in a first direction on x, the width of blue subpixels spB
It is wider, the probability of red green colour mixture between adjacent pixel p can be further decreased, optionally, the area of blue subpixels spB can be big
In the area of red sub-pixel spR or the area of green sub-pixels spG, by increasing the area of blue subpixels spB, on the one hand
The wider width of blue subpixels spB easy to implement, reducing the probability of red green colour mixture between adjacent pixel p on the other hand can
It is low by the Area Compensation blue subpixels spB luminous efficiencies for increasing blue subpixels spB, promote organic light emitting display panel
Display effect.
It is the embodiment of organic light emitting display panel provided in an embodiment of the present invention above, it is aobvious that the present invention also provides one kind
Showing device, the display device include any one organic light emitting display panel provided by the invention, have its technical characteristic and phase
The technique effect answered, details are not described herein again.
The schematic diagram of Fig. 9 display devices provided in an embodiment of the present invention, optionally, in one embodiment, display device
Including the organic light emitting display panel b that shell a and shell a is surrounded, organic light emitting display panel b be this law it is bright provide it is arbitrary
A kind of organic light emitting display panel.
By above-described embodiment it is found that organic light emitting display panel provided by the invention and display device, at least realize
Following advantageous effect：
In each pixel, setting the distance between red sub-pixel and green sub-pixels are more than two adjacent sub-pixel columns
The distance between namely the distance between red sub-pixel and green sub-pixels it is relatively large so that red sub-pixel with
The probability that colour mixture occurs between green sub-pixels reduces, and human eye for the relatively red blue colour mixture of red green colour mixture and turquoise colour mixture more
Therefore sensitivity by reducing red green colour mixture, reduces display panel and the probability of color offset phenomenon occurs, can more promote use
It experiences at family.
Although some specific embodiments of the present invention are described in detail by example, the skill of this field
Art personnel it should be understood that example above merely to illustrating, the range being not intended to be limiting of the invention.The skill of this field
Art personnel are it should be understood that can without departing from the scope and spirit of the present invention modify to above example.This hair
Bright range is defined by the following claims.
