The organic light emitting display panel that any one of the above embodiment provides has corresponding technical characteristic and technique effect, herein not
It repeats again.
By above-described embodiment it is found that the organic light emitting display panel and organic light-emitting display device of the present invention, reach
Following advantageous effect：
For loading small drive signal line, setting compensating electric capacity carries out load compensation, so that the driving letter of different loads
The organic illuminating element that number line is driven light emission luminance having the same under identical driving current is optionally mended in setting
It when repaying capacitance, will be extended out positioned at the first pole cabling of the first metal layer, offset is not present in the first pole cabling extended out, is located at first
Also there is no offsets to be carried to reduce the risk that compensating electric capacity breaks for the second pole cabling within the line width of pole cabling
The reliability of compensating electric capacity has been risen, the consistency that organic light emitting display panel is integrally shown is promoted.
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.
