Organic electroluminescence display panel generally sets pixel and power supply cabling using substrate.In the specific implementation, it is of the invention
The organic electroluminescence display panel that embodiment provides, which further includes, sets each pixel and the substrate of power supply cabling.The substrate can be glass
Substrate, flexible base board, silicon substrate etc., are not limited thereto.When organic electroluminescence display panel is applied in display device, generally
The devices such as camera, receiver can be also set, therefore in order to set the devices such as camera, receiver, in the specific implementation, in the present invention
In the organic electroluminescence display panel that embodiment provides, as shown in Fig. 2, first area a1 can include intermediate region a11, Yi Jiyou
The the first subregion a12 and the second subregion a13 that intermediate region a11 is spaced apart.Intermediate region a11 can show for organic light emission
Show the void region of the substrate in panel.In actual fabrication process, by the way that the intermediate region a11 of the substrate is cut away, with
Intermediate region a11 is set to become void region, for setting the devices such as camera, receiver in a display device.Certainly, middle area
Domain a11 can not also be cut, and be used for the cover sheet as devices such as camera, receivers, at this time, intermediate region a11
It could be provided as non-void region.Also, in order to make these proper device operations, which may be set to be transparent
Display area or non-display area.Certainly, specific set of the intermediate region of organic electroluminescence display panel is needed according to organic
The actual application environment of light emitting display panel is definite to set, and is not limited thereto.
Since organic electroluminescence display panel sets intermediate region a11, same row power supply cabling can be made directly to disconnect so that
The length of power supply cabling in the a1 of first area is less than the length of the power supply cabling in second area a2, so as to cause first area
The resistance of power supply cabling in a1 is less than the resistance of the power supply cabling in second area a2, therefore the power supply in the a1 of first area is walked
The influence of the IR Drop of line is likely less than the influence of the IR Drop of the power supply cabling in second area a2.In order to make the two areas
The IR Drop of power supply cabling in domain are identical in allowable range of error, can walk each power supply in the a1 of first area
The quantity of the corresponding via 300 of line 100 is less than the number of the 100 corresponding via 300 of each power supply cabling in second area a2
Amount, so that the resistance of the power supply cabling in the two regions can be identical in allowable range of error, so that the two regions
In power supply cabling IR Drop it is identical in allowable range of error.Wherein, in fig. 2, although in the second area a2 shown
The corresponding via 300 of partial power cabling 100 quantity be less than first area a1 in 100 corresponding mistake of partial power cabling
The quantity in hole 300, but it is only the set-up mode of schematically illustrate via, does not represent in actual setting often row power supply cabling
The quantity of 100 corresponding vias.In the specific implementation, often the quantity of the corresponding via of row power supply cabling can pass through analogue simulation
It is definite to calculate, so that the resistance after different electrical power cabling compensates cabling parallel connection with corresponding power supply can be in the model of error permission
Enclose interior identical.
