OLED device with macro extractor
摘要:
The invention relates to an OLED device with a stack comprising: a light emitting organic layer (2), a cathode layer (1), and a transparent anode layer (3), the organic layer (2) being arranged between the cathode layer (1) and the anode layer (3), wherein a macro extractor layer (5) is arranged on top of a transparent substrate (4), wherein the macro extractor in optical contact with the transparent substrate (4), and wherein the macro extractor (5) layer comprises a plurality of mirror surfaces which extend from the bottom to the top of the macro extractor layer (5), preferably embedded in a matrix which has a refractive index matching the one of the transparent substrate. Preferably, the macro extractor layer comprises a crash glass device with a pre-stressed crash glass pane (6) having air-filled cracks (9). Since these cracks (9) act as mirrors for the light emitted by the organic layer (2), trapping of light is avoided and, thus, light extraction from the device is enhanced.
