LIGHT-EMITTING DIODE ASSEMBLY Russian patent published in 2013 - IPC G09F13/22 

FIELD: physics.

SUBSTANCE: first organic light-emitting diode (LED) (101) has a first light-emitting layer (105), lying on an electrode of a first substrate (107), and an opaque first electrode (109), lying on the first light-emitting layer (105). A second organic LED (103) is placed on top of the first LED (101) and has a second light-emitting layer (113), lying on an electrode of a second substrate (115), and an opaque second electrode (117) lying on the second light-emitting layer (113). The electrode of the first substrate (107) has a shape which corresponds to a light image transmitted by the first LED (101). The electrode of the second substrate (115) has a shape which corresponds to a light image transmitted by the second LED (103). The first LED (101) lies on the first substrate (108). The second LED (103) lies on the second substrate (121). An adhesive (123) layer is provided between said first substrate (108) and said second substrate (121).

EFFECT: easier assembly.
