Abstract
An OLED display comprising a substrate; at least one heat insulating layer disposed over the substrate; a first electrode located over the heat insulating layer and having a thermal conductivity higher than the heat insulating layer; a plurality of thermal contacts provided through the heat insulating layer between the first electrode and the substrate, the thermal contacts comprising material having a thermal conductivity higher than that of the heat insulating layer; one or more organic layers, at least one of which is a light emissive layer, disposed over the first electrode; and a second electrode disposed over the one or more organic layers.
Claims19
An OLED device, comprising:
- a) a substrate;
- b) at least one heat insulating layer disposed over the substrate;
- c) a first electrode located over the heat insulating layer and having a thermal conductivity higher than the heat insulating layer;
- d) a plurality of spatially separated thermal contacts for the first electrode, each formed in a separate corresponding via provided through the heat insulating layer between the first electrode and the substrate, the thermal contacts comprising material having a thermal conductivity higher than that of the heat insulating layer and extending from the first electrode through the via to the substrate or a layer formed on the substrate but which does not conduct current;
- e) one or more organic layers, at least one of which is a light emissive layer, disposed over the first electrode;
- and
- f) a second electrode disposed over the one or more organic layers.
