Embodiment Construction

[0022] figure 1 A light emitting diode arrangement comprising a first diode 101 and a second diode 103 is disclosed. The first diode comprises one or more light emitting layers 105 , eg organic light emitting layers, arranged on a substrate layer 108 . Furthermore, a first electrode 107 is provided on the substrate layer 108 and a second electrode 109 is provided on the surface of the light emitting layer 105 . The first diode 101 can be sealed with a cover 111 .

[0023] The second light emitting diode 103 is arranged on the first light emitting diode 101 and accordingly comprises one or more light emitting layers 113 , eg organic light emitting layers, arranged on the substrate electrode 115 . The light emitting layer 113 is covered by an electrode 117, wherein a cover 119 is provided so as to seal or cover the second light emitting diode. The substrate electrode 115 is arranged on the substrate 121 . Such as figure 1 As depicted, substrates 108 and 121 are arranged bac...

Abstract

The invention relates to a light emitting diode arrangement comprising a first light emitting diode (101), in particular an organic light emitting diode, comprising a first light emitting layer (105) and a first electrode (109) arranged on the first light emitting layer (105), and a second light emitting diode (103), in particular an organic light emitting diode, being arranged upon the first light emitting diode (101), the second light emitting diode (103) comprising a second light emitting layer (113) and a second electrode (117) arranged on the second light emitting layer (113), the second electrode (117) being translucent.

Description

technical field [0001] The present invention relates to light emitting diodes, in particular organic light emitting diodes. Background technique [0002] Light-emitting diodes, in particular organic light-emitting diodes (OLEDs), are not only suitable for display or lighting, but can also be employed for signaling information in the form of illuminated signs, for example determined by a luminous pattern. However, known light emitting diodes enable the emission of only one pattern, eg representing some kind of information in one direction. Therefore, this light-emitting diode can only be used as a traditional sign. In order to emit different patterns representing different information, for example complex display means such as liquid crystal displays can be used. However, display devices are more expensive and require additional control devices. [0003] US 2005 / 0057149 A1 discloses a display electronic device having two OLED displays arranged on opposite sides of the same...
