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.
