Facilitating improved luminance uniformity in organic light emitting diode device panels |
摘要 |
An apparatus facilitating luminosity uniformity across organic light emitting diode (OLED) device is provided. In one embodiment, the apparatus can include an organic light emitting diode (OLED) device including: an anode; a semiconductor material coupled to the anode; and a cathode coupled to the semiconductor material. The apparatus can also include a hollow heat sink coupled to the cathode and configured to reduce a temperature of the OLED device resulting in a first temperature of the OLED device being a first value in a first region of the OLED device and a second temperature of the OLED device being a second value in a second region of the OLED device. A temperature distribution characterized by a change in temperature from the first temperature to the second temperature to a third temperature is approximately Λ-shaped from the first region to the second region to the third region. |

1. An apparatus, comprising:
an organic light emitting diode (OLED) device comprising:
an anode;a semiconductor material coupled to the anode; anda cathode coupled to the semiconductor material; and an air-filled heat sink coupled to the cathode and configured to reduce a temperature of the OLED device resulting in a first temperature of the OLED device being a first value in a first region of the OLED device and a second temperature of the OLED device being a second value in a second region of the OLED device. |
