Impact of Joule heating on the brightness homogeneity of organic light emitting devices
Joule heating and its impact on the brightness homogeneity are investigated since the luminance distribution is a key issue in large area organic light emitting diodes. In addition to previous reports, it is also important to consider the device temperature as a main factor for determining the lumin...

| description | Joule heating and its impact on the brightness homogeneity are investigated since the luminance distribution is a key issue in large area organic light emitting diodes. In addition to previous reports, it is also important to consider the device temperature as a main factor for determining the luminance homogeneity. At a luminance of
1000
cd
∕
m
2
the active area reaches an average temperature of
40.6
°
C
and a peak of
46.2
°
C
. The increased device temperature is leading to higher local current densities resulting in a reduced brightness homogeneity. Modeling confirms these results and can be used for further device layout optimization. |
