LIGHT-EMITTING ELEMENT HAVING AN OLED OR QLED

The invention relates to a light-emitting element that comprises a planar OLED (organic light-emitting diode) or a planar QLED (quantum dot light-emitting diode) for producing a first light. Furthermore, the element comprises an optical influencing element (40) having a light-emitting surface (62) f...

More Information
Summary:The invention relates to a light-emitting element that comprises a planar OLED (organic light-emitting diode) or a planar QLED (quantum dot light-emitting diode) for producing a first light. Furthermore, the element comprises an optical influencing element (40) having a light-emitting surface (62) for emitting a second light, wherein the second light is formed from the first light by means of an optical influence caused at least in part by the optical influencing element (40). The optical influencing element (40) allows the light yield to be increased and the directional behavior of the second light to be influenced in a specific manner.
