Embodiment
In order to make the purpose of the present invention, technical solution and advantage are clearer, below in conjunction with the accompanying drawings, to the embodiment of the present invention
The organic electroluminescence display panel of offer and the embodiment of display device are described in detail.It should be appreciated that following institute
The preferred embodiment of description is merely to illustrate and explain the present invention, and is not intended to limit the present invention.And in situation about not conflicting
Under, the feature in embodiment and embodiment in the application can be mutually combined.
Each layer film thickness, size and shape do not reflect the actual proportions of organic electroluminescence display panel, mesh in attached drawing
Simply schematically illustrate present invention.
Organic electroluminescence display panel provided in an embodiment of the present invention, as shown in Figures 2 and 3, organic electroluminescence display panel
Viewing area is provided with a plurality of power supply cabling 100 extended along column direction, and power supply cabling is used to provide power supply from driving IC to pixel
Voltage, viewing area are additionally provided with a plurality of power supply connection cabling 200 of line direction extension, cabling 200 are connected by power supply by power supply
100 lateral connection of cabling, so as to reduce IR drop.Viewing area includes the first viewing area a1 and the second viewing area (is not got the bid in figure
Go out), the first viewing area a1 is located at the corner of display screen, and edge contour is arc-shaped, and it is aobvious that described first is removed in viewing area
The other parts for showing area a1 are the second viewing area.Power supply cabling 100 includes the first sub- 101 and second sub- power supply cabling of power supply cabling
102, every first sub- power supply cabling 101 can be divided into Part I P1 and Part II P2, and Part I P1 is positioned at the first display
Area a1, Part II P2 are located at the second viewing area, and the line width x1 of the Part I P1 of the first sub- power supply cabling 101 is less than second
Divide the line width x2 of P2.
First viewing area of organic electroluminescence display panel provided by the invention is located at the corner of display screen, and edge contour
The other parts that the first viewing area a1 is removed to be arc-shaped, in viewing area are the second viewing area.First sub- power supply cabling
The line width of Part I is less than the line width of Part II, can so make the resistance of the Part I of the first sub- power supply cabling big,
The IR drop of Part I are made to become larger, the electric current of the pixel of the first viewing area diminishes, so that the first viewing area pixel light emission brightness
Less than the second viewing area pixel light emission brightness.So the present invention can be improved with the sawtooth sense near circle of confusion arc edge contour
Zigzag situation near showing edge profile, lifts display quality.And without changing the design of driving battery core, without for this
The individually designed drive circuit of scheme, technique are relatively simple.
As shown in figure 4, the edge contour of the first viewing area a1 is arc-shaped, the first viewing area is the adjacent circle in viewing area corner
The scope of the picture element matrix region of curved edge contour line B*C, wherein B and C are 2.5mm~5mm.Certainly, organic light emission is shown
Show that the specific of the first viewing area a1 of panel sets needs according to the actual application environment of organic electroluminescence display panel to set really
It is fixed, it is not especially limited herein.
In some optional embodiments, in organic electroluminescence display panel, the Part I P1 of the first sub- power supply cabling 101
Line width be gradually reduced along column direction, refer to Fig. 5, the Part I P1 of the first sub- power supply cabling 101 is along column direction
